1. Process analysis of plastic products Before mold design, the designer should fully analyze and study whether the plastic product conforms to the principle of injection molding processing. It is necessary to carefully negotiate with the product designer and reach a consensus. This includes conducting necessary discussions on the geometric shape, dimensional accuracy and appearance requirements of the product, and avoiding unnecessary complexity in mold manufacturing as much as possible. 2. Mold structure design A set of high-quality molds not only requires good processing equipment and skilled mold manufacturing workers, but another very important factor is to have good mold design, especially for complex molds, whether the mold design is good or bad It accounts for more than 80% of the mold quality.

A good mold design is: under the premise of meeting the requirements of customers, the processing cost is low, the processing difficulty is small, and the processing time is short. To do this, we must not only fully digest the customer's requirements, but also have an understanding of the injection molding machine, mold structure, processing technology and mold factory's own processing capabilities. Therefore, in order to improve the design level of injection molds, the following points should be done: ① understand every detail in the design of each set of molds, and understand the purpose of each part in the mold.

②When designing, refer to previous similar designs, and understand the situation in mold processing and product production, and learn from the experience and lessons. ③ Learn more about the working process of the injection molding machine to deepen the relationship between the mold and the injection molding machine. ④ Go to the factory to understand the process of processed products, and understand the characteristics and limitations of each processing.

⑤Know the results of the mold trial and the situation of the mold modification of the mold designed by yourself, and learn lessons. ⑥ Try to adopt the mold structure that was more successful in the past when designing. ⑦ Learn more about the impact of water entering the mold on the product.

⑧Research on some special mold structures and understand new mold technologies.
