Injection mold is an important process equipment for the production of various industrial products. With the rapid development of the plastic industry and the promotion and application of plastic products in aviation, aerospace, electronics, machinery, ships and automobiles and other industrial sectors, the requirements of products on molds are also increasing. With the coming of age, the traditional mold design method has been unable to 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 intensity. On the other hand, they have great advantages.
In the processing of injection molds, all kinds of CNC machining are used. The most widely used are CNC milling and machining centers. The application of CNC wire cutting and CNC EDM in mold CNC machining is also very common. Wire cutting is mainly used in the processing of various straight-walled molds, such as concave and convex dies 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.
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.
In order to adapt to market diversification and trial production of new products, it should be the development trend of mold production technology in the next 5 to 20 years by applying rapid prototyping technology and rapid molding technology to rapidly manufacture molding dies, plastic injection molds or die-casting molds.
