Injection molds are important process equipment for the production of various industrial products. With the rapid development of the plastics industry and the popularization and application of plastic products in aviation, aerospace, electronics, machinery, ships, automobiles and other industrial sectors, the requirements for molds are also increasing. More and more, traditional mold design methods can no longer meet today's requirements. Compared with traditional mold design, computer-aided engineering (CAE) technology can improve productivity, ensure product quality, or reduce costs and labor. In terms of strength, they have great advantages.

1. Basic classification of injection molds

Injection molds are divided into two types: thermosetting plastic molds and thermoplastic plastic molds according to their molding characteristics; , Among them, the hot pressing mold can be divided into three types: overflow type, semi-overflow type and non-overflow type according to the overflow method. The injection mold can be divided into cold runner mold and hot runner mold according to the gating system. According to the way of loading and unloading, it can be divided into two types: mobile type and fixed type.

2. Application of injection mold in CNC milling and machining center

In the processing of injection molds, various CNC machining are used. The most widely used are CNC milling and machining centers. CNC wire cutting and CNC EDM are also widely used in mold CNC machining. Wire cutting is mainly used in Processing of various straight-walled molds, such as concave and convex molds in stamping, inserts and sliders in injection molds, electrodes for EDM, etc. For mold parts with high hardness, machining methods cannot be used, and EDM is mostly used. In addition, EDM is also used for sharp corners, deep cavity parts, and narrow grooves of mold cavities. The CNC lathe is mainly used to process the standard parts of the mold rod, as well as the mold cavity or core of the rotary body, such as the injection mold of the bottle body and the basin, and the forging mold of the shaft and disc parts. In mold processing, the application of CNC drilling machine can also play a role in improving processing accuracy and shortening processing cycle.

3. Application of injection molds in modern manufacturing

Molds are widely used, and almost all the forming and processing of product components in modern manufacturing require the use of molds. Therefore, the mold industry is an important part of the national high-tech industry and an important and valuable technical resource. Optimize the structural design of the mold system and make it more intelligent, improve the injection molding process and mold standardization level, improve the precision and quality of mold manufacturing, and reduce the surface grinding and polishing workload and manufacturing cycle of molded parts; research and application are aimed at high-performance, easy-cutting special materials used in mold-like parts to improve the performance of molds; in order to adapt to market diversification and new product trial production, rapid prototyping technology and rapid molding technology are applied to rapidly manufacture molding dies, plastic injection mold or die-casting mold, etc., should be the development trend of mold production technology in the next 5 to 20 years.
