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. In addition to the absence of microcosm, trapped air, and strain, the finish must be very high.

Since the auto lamp mould is a large mold and the parting surface is complex,

Commodity mould is a kind of mold.
