Background

As is known, injection molding is an efficient method for manufacturing plastic parts, and the guarantee for realizing high-efficiency molding is an injection molding mold. The injection molding process comprises four stages of mold closing, injection, pressure maintaining and cooling, wherein in the whole injection molding cycle, the cooling takes the longest time, and the cooling takes about 3/4 times of the whole cycle. Therefore, the key to improving the production efficiency is how to reduce the cooling time, so the cooling efficiency needs to be improved. In addition, the different cooling rates at different parts can cause uneven shrinkage of the plastic parts due to different structures of the plastic parts. To obtain more uniform cooling, the temperature of the mold cavity must be kept substantially uniform at all locations, and therefore, the uniformity of the temperature distribution of the mold cavity is another key factor controlling the cooling of the plastic part, and this factor mainly affects the performance of the plastic part.

The traditional cooling water channels (such as jet flow type, bushing type and clapboard type) can not realize the uniform cooling of parts, and the processing is realized by drilling or adopting a mosaic type mould structure, the drilling can only process linear cooling water channels, and plastic products often have complex curved surface structures, so the distances between the linear cooling water channels and the surface of a cavity are unequal, the uniform cooling of the parts is difficult to realize, and the formed products have poor performance.
