The pallet is a relatively common item in our daily life. It is also a very long night in industrial production. In mold making, Industrial tray molding technology is becoming more and more perfect.
There are four ways to mold pallets, one of which is injection molding, and this method requires an injection molding machine. The injection molding machine can be divided into a clamping device and an injection device. The mold clamping device is a direct pressure method that opens and closes the mold to perform the demolding operation and uses a hydraulic cylinder to directly open and close the mold. The injection device heats and melts the resin and then injects it into the mold. At this time, the screw is rotated, and the resin put into the hopper stays at the front end of the screw as shown in the figure, and it is stored after a stroke equivalent to the amount of resin required. Projected. When the resin flows in the mold, the moving speed of the screw is controlled and the pressure (holding pressure) is used to control after the resin is filled. When it reaches a certain screw position or certain injection pressure, it switches from speed control to pressure control.
Some simple introduction and understanding of the above injection molding machine. If you want to use the injection molding machine well and make a good mold, more experience is needed.
