dimensional shape. The mold generally includes two parts, a movable mold and a fixed mold (or a punch and a concave mold), which can be divided and closed. The mold is a precision mold with complex shape, which bears the expansion force of the blank, and has high requirements on structural strength, rigidity, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important signs of the level of machinery manufacturing.

Plastic mould is the abbreviation of a combined mold for compression molding, extrusion molding, injection molding, blow molding and low foam molding. The coordinated changes of the mold convex, concave mold and auxiliary molding system can process a series of plastic parts of different shapes and sizes. It mainly includes a concave die with variable cavity composed of a concave die combination substrate, a concave die assembly and a concave die combination card plate. A punch with a variable core composed of side-cut composite panels. In order to improve the performance of plastics, various auxiliary materials, such as fillers, plasticizers, lubricants, stabilizers, colorants, etc., must be added to the polymer to become a plastic with good performance. Among them, synthetic resin is the main component of plastic, and its content in plastic is generally 40% to 100%. Due to the large content and the properties of resins that often determine the properties of plastics, people often regard resins as synonymous with plastics. For example, polyvinyl chloride resin is confused with polyvinyl chloride plastic, phenolic resin and phenolic plastic. In fact, resin and plastic are two different concepts. Resin is an unprocessed raw polymer. It is not only used to make plastic, but also a raw material for coatings, adhesives and synthetic fibers. Except for a very small part of plastic, it contains 100% In addition to resin, most plastics need to add other substances besides the main component resin.

The appearance requirements of medical molds are relatively high.Since the auto lamp mould is a large mold and the parting surface is complex, the forming part and the template adopt an integrated structure, that is, the fixed mold A plate of the mold is the fixed mold forming part, and the movable mold B plate of the mold is the moving mold formingCommodity mould is a kind of mold. The design of thin-wall daily necessities mold needs to consider the following points: product parting surface, product wall thickness design, exhaust design of daily necessities mold, waterway design of daily necessities mold, and blowing position of daily necessities mold With the direction design, these problems directly determine the success or failure of a thin-walled daily necessities mold. Commodity molds need to realize fully automatic production: thin-walled products are an industry with small profits but quick turnover. Equipping with a manipulator can make the production run faster. The manipulator can help you stack directly, and the belt can be directly packaged and shipped. The daily necessities molds for all stamping parts on automobiles are called "automotive stamping daily necessities molds".
