What is plastic processing of moulds?

Answer:

Although the structure of the mold may be varied because of the variety and performance of plastics, the shape and structure of plastic products and the type of injection machine, but the basic structure is consistent. The mold is mainly composed of pouring system, temperature regulating system, molding parts and structural parts. The gating system and molding parts are in direct contact with the plastic parts and products as plastics and change, is the most complex in the mold, the biggest change, part of the processing requirements of the highest accuracy and smoothness.Pouring system refers to the flow of plastic from the nozzle into the mold cavity, including the main road, cold material hole, diversion channel and gate. Forming parts are parts of the shape of the product, including moving die, fixed mold and cavity, core, forming rod and exhaust port, etc..China plastic mould in promoting high technology driven and pillar industry application requirements, formed a huge industrial chain, from upstream raw materials industry and machining and testing equipment to the downstream machinery, automobile and motorcycle, household appliances, electronic communications, building materials and other major industrial applications, the development of a plastic mold vitality.With the rapid development of China's automotive, home appliances, electronic communications, building materials.
With the rapid development of plastic industry and the continuous improvement of general and engineering plastics in the field of strength, the range of application of plastic products is also expanding, and the consumption of plastic products is also rising.A plastic mold is a tool for the manufacture of plastic products consisting of a number of parts in which the molding cavity is formed. Injection molding, mold clamping in injection molding machine, the molten plastic is injected into the molding cavity, and cooling in the cavity shape, and then die down to separate out the system through the top products from the top of the left mold cavity, the mold is closed again for the next injection, the injection molding process is carried out of the cycle.The general plastic mould is composed of two parts, the moving die and the fixed mould. The moving die is installed on the moving template of the injection molding machine, and the fixed die is installed on the fixed template of the injection molding machine. In the injection molding, the moving die and the fixed die are closed to form a casting system and a mold cavity. When the mold is opened, the moving die and the fixed die are separated so as to remove the plastic product.
For a combined plastic mold, injection molding, compression molding, extrusion blow molding and low foaming, which mainly comprises a die having a variable cavity composed of concave die and die combination of substrate components and die combination lock plate, the convex die combination substrate, punch assembly, punch card has a convex combination the composition of the core mold variant plate, cavity blocking assembly and side cutting plate. The coordinated change of die, punch, die and auxiliary forming system. Can be processed in different shapes, different sizes of series of plastic parts. Plastic processing industry and plastic molding machine matching, give plastic products with complete configuration and precise size tools. Because of the plastic varieties and processing methods of various plastic molding machine and plastic product structure is simplified, so the plastic mold of the type and structure is various.
