The slider is a mold component that can slide perpendicular to the mold opening and closing direction or at a certain angle to the mold opening and closing direction during the mold opening action of the mold. When the product structure makes it impossible for the mold to be demolded normally without the use of the slider, the slider must be used. The material itself has the appropriate hardness, wear resistance, and enough to withstand the friction of movement. The hardness of the cavity part or core part on the slider should be the same level as the other parts of the cavity core. The slider should move a certain distance during the mold opening process. After the front and rear molds are completely separated, the slider should be able to return safely.
Mold is important to 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 for molds are becoming more and more important. High, traditional mold design methods have 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, which have great advantages.
Using CAE technology, the entire injection molding process can be simulated and analyzed on the computer before the mold is processed to accurately predict the filling, pressure holding, and cooling of the melt, as well as the stress distribution, molecular and fiber orientation distribution in the product, and the product's Shrinkage and warpage, etc., so that designers can identify problems early and make changes in time, rather than wait until the mold is tried and then repair the mold. This is not only a breakthrough in traditional mold design methods but also has great technical and economic significance in reducing or even avoiding mold repair and scrap, improving product quality, and reducing costs.
The design of plastic molds should not only use CAD technology but also use CAE technology, which is an inevitable trend of development. Mold is important to process equipment for industrial production. Due to the use of molds to process and form parts, has a series of advantages such as high production efficiency, good quality, saving raw materials and energy, and low cost. It has become an important means and process development direction of contemporary industrial production. Mold manufacturing is a complex production process with urgent production cycle requirements and high technical requirements. In short, the mold has the characteristics of complex structure, complex profile, high precision requirements, high hardness of materials used, and short manufacturing cycle. Applying CNC machining for mold manufacturing can greatly improve processing accuracy, reduce manual operations, improve processing efficiency, and shorten the mold manufacturing cycle. At the same time, the CNC machining of molds is typical and has higher requirements than the CNC machining of ordinary products. In the processing of molds, all kinds of CNC machining are used. The most used ones are CNC milling and machining centers. The application of CNC wire cutting and CNC EDM in the CNC machining of molds is also very common. Wall mold processing, such as concave and convex dies in stamping, inserts, 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 molded 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 a CNC drilling machine can also play a role in improving processing accuracy and shortening the 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, in countries with developed manufacturing industries, the mold market is extremely broad; in countries with developed molds, the manufacturing industry must also be very developed and prosperous. 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 the CAD/CAE/CAM of the mold parts, make them more intelligent, improve the mold forming process and mold standardization level, improve the mold manufacturing accuracy and quality, and reduce the surface grinding, Polishing workload and manufacturing cycle; research and apply high-performance, easy-cutting special materials for various types of mold parts to improve the performance of molds; to adapt to market diversification and new product trial production, apply rapid prototype manufacturing technology and Rapid mold making technology, to rapidly manufacture molding dies, plastic injection molds or die casting molds, should be the development trend of mold production technology in the next 5 to 20 years.
