[0002] At present, with the rapid development of the automobile industry, the demand for automobile parts is increasing. The use of lightweight automobile parts in automobiles can save fuel to a certain extent, promote environmental protection and the recycling of resources. Some parts can use plastics instead of expensive metal materials. The use of plastic injection moldings in automobiles is becoming more and more common. Now automobile injection molding parts need to be cast and molded using injection molding machines. However, the existing injection molding machines are prone to incomplete filling of the gate and large shrinkage during casting, resulting in concave surface of the injection molding machine structure and low product qualification rate.
