Key technologies of die closing machine

The clamping mechanism must be able to provide enough clamping force to prevent the overflow of products. Therefore, the role of force amplification in the clamping process must be considered in the design. On the other hand, the injection molding machine is a kind of intermittent working equipment. Previous research has realized that its molding cycle is an important factor determining the production efficiency of the injection molding machine, and the mold closing process usually takes a long time. Therefore, improving the speed of mold opening and closing is an effective way to improve the efficiency of the injection molding machine, but when the mold is close to closing, too fast mold closing speed may cause mold damage. It can be seen that the clamping mechanism of the injection molding machine can be divided into three processes: rapid clamping - improving efficiency; Low-speed mold closing - protect the mold; High-pressure mode locking - realize force amplification.
In the theoretical analysis of the mechanism, because the overall structure and stress state of the clamping mechanism are very complex, it is very difficult to consider the influence of all factors. This requires finding out the main factors affecting the accuracy, ignoring the secondary factors, and making necessary simplification of the overall structure to make the analysis smooth.
