We all know that there are so many parts in a car, and each one is very important. And auto reflective part mold is also very important.

When the front side is in an emergency and needs to brake quickly, observe the center rearview mirror to know if there is a car that is closely following behind. This way, according to the distance from the front, you can properly relax the brakes to avoid rear-end vehicles.

When driving, every driver should be mindful and pay attention to the conditions around the car, especially the center rearview mirror. The distance of the car behind can be judged through the center rearview mirror. It just happens to be seen in the center rearview mirror. When the rear car is on the front wheel, the front-to-rear distance is about 13 meters, when you see the center grid, it is about 6 meters, and when you just can’t see the center grid, it is about 4 meters front and rear.

For auto radiator tank plastic mould , it also has its role.

Most people have only heard of plastic pipe fitting injection mould , but they are not very familiar with it. So what are the production standards of plastic pipe fitting injection mould?

When making plastic pipe fitting injection mould, we should avoid using a grinder to polish the mold as much as possible. If you must use a grinder to process, you must use oil stone to save light (parting surface). The surface treatment of the inner mold surface must be Follow the form or other officially notified technical requirements. The processing lines (wire cutting, milling machine, gong bed, spark machine) on the non-adhesive plane should also use oilstone to save brightness. Inner mold materials and mold blank grade requirements must be purchased according to the order or the technical requirements formally confirmed during the design review process. The material certificate must be provided, and if it is a hard mold, a heat treatment report must be provided. Relevant proof. The front and rear inner molds, inserts, row positions, inclined tops, straight tops (push blocks), shoveling chickens, etc. of the mold need to be processed with a waist circular pit on the bottom or side to engrave the material name and hardness.

It is difficult for children to resist the temptation of toys, and sometimes adults have to compromise with them, but children are very fragile, so we also need to choose blocks with good safety performance when choosing blocks. If you want the performance of the building blocks to be good, then first of all the child building blocks mould must be good. So how do we choose children’s building blocks or molds?

When we buy building block toys for children, we must choose toys that are suitable for children of this age. Do not choose high-end and complex toys for young children, and use learning tools for any age group. Don’t think about buying a high-end toy and using it for many years, saving money and trouble. This is tantamount to facilitating growth, which is not a good thing. However, when economic conditions do not allow it, this is also a helpless move.

The second most important thing is the safety performance of the toy, that is, the material used in the toy. Some toys have relatively small particles, so they are not suitable for younger children to play for fear of accidental ingestion; while some toys are large, but they are not edible materials and are not suitable for children to play; other toys may It’s sharper, it will hurt the child by mistake, and it’s not very suitable. Therefore, when choosing toys for children, everything should be child-oriented.

Many drivers know that when the temperature of the car’s water tank is too high, it must stop. The car radiator water tank and the auto radiator tank plastic mould are very important.

After the temperature of the water tank increases, we first need to check. At the beginning of the engine operation, the water temperature is thousands of quick; when the water temperature gauge indicates 80, the heating rate slows down, indicating that the thermostat is working normally. On the contrary, if the water temperature has been rising rapidly, when the internal pressure reaches a certain level, the boiling water suddenly overflows, which indicates that the main valve is stuck and suddenly opened.

When the water temperature gauge indicates 70℃-80℃, open the radiator cover and the radiator drain switch, and feel the water temperature with your hands. If they are hot, the thermostat is working normally; if the water temperature at the water inlet of the radiator is low and the radiator is filled There is no water or very little water flowing out of the water inlet pipe of the chamber, indicating that the main valve of the thermostat cannot be opened.

Every part of a car is very important, as is the mirror made by the auto reflective part mold .

We all know that plastic chair injection mould test molds are generally a whole, only there is a small hole at the bottom of the test mold. How to drag the test mold out intact and undamaged is the most concerning issue. Here are some simple steps to teach you:

First, apply oil to the inside of the test mold before injection molding to facilitate the later removal of the mold; secondly, after brushing the oil, put a small piece of waste paper on the small hole of the test mold to protect the small hole of the test mold from being blocked by concrete; Finally, the air pump is connected with the test mode, so that a complete test mode can be dragged out.

If there is no air pump, it can only be pushed out or knocked out from the bottom hole with steel bars, etc., put a cloth on the edge of the trial mold or a certain platform, and then invert the plastic mold. Don’t use force when knocking the plastic mold. Too large, otherwise it will damage the test mold.

The electrical appliance mould can also use this method.

My country’s plastic mold industry has gone through a long time from its inception to the present, and naturally, it has also made great development, so the level of molds has also been improved to a certain extent. The plastic box mold is constantly improving the quality of the mold. Today we take a look at the gate location of the plastic box mold.

When determining the gate position, the following principles should adhere to  1. The rubber injected into each part of the mold cavity should be as even as possible.  2 The rubber injected into the mold should be uniform and stable at all stages of the injection process.  3. The possible occurrence of weld marks, bubbles, cavities, vacant positions, insufficient injection, and spraying, etc. should be considered.  4. The operation of the dewatering port should be made as easy as possible, preferably automatic operation.  5. Pour The position of the mouth should be coordinated with all aspects.

Many molds have different gate options, and plastic dustbin mould is the same.

We all know that the production requirements of the mold are still very high, and the production requirements of the plastic dustbin mould are equally high.

To make trash can molds, you need to choose HDPE (low-pressure high-density polyethylene) with high impact strength; all plastic trash cans we see are colored, especially after the implementation of garbage classification, different colored trash cans represent different Sorting garbage ensures that the color of the product is uniform and the gloss is good; the price of the new mold is relatively high. Generally, each part of the plastic trash can needs to be mold, such as the barrel body, the lid, and the handle. The injection molding process is to Molten plastic is injected into plastic product molds by pressure, and cooled and molded to obtain various plastic trash cans. Printing is to add exquisite patterns or text to the plastic trash can. Note that there are two parts, one is a large piece of printed paper. Printing on plastic products, the other is small-area spray printing, which is done by hand; the finished parts are assembled and ready to leave the factory.

The production process of plastic box mold is similar, but there will be some slight differences.

The pallet is a horizontal platform device used for consolidating, stacking, handling, and transporting goods and products as a unit load. It is generally made of wood, metal, fiberboard, and PP plastic, which is convenient for loading, unloading, handling, and storing unit materials and small quantities of materials. The industrial pallet is usually heavy, large in area, and its carrying capacity is many times larger than that of daily pallets, and it can carry several tons of goods. Today we are talking about Industrial tray molding .

Traditional forming simulation software is based on the central layer model of the product. The user first abstracts the product into approximate planes and curved surfaces. These surfaces are called the central layer. Generate two-dimensional planar triangular grids on these central layers, use these two-dimensional planar triangular grids to perform finite element calculations, and display the final analysis results on the midplane. The injection molding product models mostly use three-dimensional solid models. Due to the inconsistency of the two models, secondary modeling is inevitable.

Because the shapes of injection molded products are complex, diverse and ever-changing, it is difficult to extract the center layer from the three-dimensional entity. The extraction process is very cumbersome and time-consuming. Therefore, designers are afraid of simulation software. This has become a bottleneck in the promotion and application of forming simulation software.

As mobile phones and computers are getting faster and faster, in addition to pursuing experience and quality upgrades, people also have more and more requirements for appearance and importance. With the development of thin wall plastic mold and other thin-walled parts, thin-wall injection molding technology is highly valued by people, which promotes product design, mold design, injection molding machine, and material selection, and thin-wall injection molding numerical simulation technology in thin-wall injection molding. Research and application development.

Technology The filling process and cooling process of conventional injection molding are intertwined. When the polymer melt flows, the melt front meets the relatively low-temperature core surface or cavity wall, and a layer of condensation is formed on the surface. The melt continues to flow forward in the condensation layer, and the thickness of the condensation layer has a significant effect on the flow of polymer. It is necessary to conduct a more in-depth and comprehensive study on the properties of the condensate layer in thin-wall injection molding. Therefore, the numerical simulation of thin-wall injection molding still needs to do a lot of other work.

In fact, the technology of plastic pipe fitting injection mould is relatively not very mature, and we still need to make certain improvements in many aspects. But with the continuous advancement of science and technology, I believe we will do better and better.

Home appliances are indispensable in our lives. Many electrical appliances can bring us a lot of conveniences, such as mobile phones, computers, refrigerators, TVs, etc., can bring great convenience to our lives. Only a few, most electrical appliances need electrical appliance mould to complete.

A mold is not a part but is different from a tool. The mold is a set of molding equipment that integrates parts. Modern manufacturing not only requires molds with high precision and long life but also requires molds with ingenious structural design, well-studied molding mechanism, good use performance, and funny manufacturing performance, and other comprehensive functions.

On-site mold inspection technology The development of precision molds has increasingly higher requirements for measurement. The precision three-coordinate measuring machine has been restricted by the environment for a long time and is rarely used in the production site. The new generation of three-coordinate measuring machines have temperature compensation and adopt anti-vibration materials, improve dust-proof measures, improve environmental adaptability and use reliability so that they can be easily installed in the workshop to realize the characteristics of measuring on-site.

In addition to household appliance molds, plastic chair injection mould also require good performance.
