A combined plastic mould for compression moulding, extrusion moulding, injection moulding, blow moulding and low foam moulding, which mainly includes a variable cavity composed of a concave mould combined substrate, a concave mould assembly and a concave mould combined card board The concave mould is a convex mould with a variable core composed of a convex mould combined substrate, a convex mould assembly, a convex mould combined pallet, a cavity cutting component and a side cutting combined board. Coordinated change of mould convex, concave mould and auxiliary forming system. It can process plastic parts of different shapes and sizes. In the plastics processing industry, it is matched with plastic moulding machines to give plastic products complete tools and precise dimensions. Due to the variety of plastics and processing methods, the structure of plastic moulding machines and plastic products is also complicated, so the types and structures of plastic moulds are also diverse.


With the rapid development of the plastics industry and the continuous improvement in strength and other aspects of general and engineering plastics, the application range of plastic products is also expanding, and the amount of plastic products is also rising.



Plastic mould is a tool for producing plastic products. It is composed of several groups of parts, and there is a moulding cavity in this combination. During injection moulding, the mould is clamped on the injection moulding machine, the molten plastic is injected into the moulding cavity, and cooled and shaped in the cavity, then the upper and lower moulds are separated, and the product is ejected from the cavity through the ejection system to leave the mould, and finally the mould is closed. For the next injection, the entire injection process is cyclic.



The general plastic mould is composed of a movable mould and a fixed mould. The movable mould is installed on the moving mould of the injection moulding machine, and the fixed mould is installed on the fixed mould of the injection moulding machine. During injection moulding, the movable mould and the fixed mould are closed to form a pouring system and a cavity. When the mould is opened, the movable mould and the fixed mould are separated to take out the plastic product.



Although the structure of the mould may vary due to the variety and performance of plastics, the shape and structure of plastic products, and the type of injection machine, the basic structure is consistent. The mould is mainly composed of pouring system, temperature adjustment system, moulding parts and structural parts. Among them, the pouring system and the moulded parts are the parts that are in direct contact with the plastic, and change with the plastic and the product. They are the most complex and the most varied parts in the mould, which require the highest processing finish and precision.



The pouring system refers to the part of the flow path before the plastic enters the cavity from the nozzle, including the main flow path, the cold material cavity, the flow path and the gate. moulded parts refer to various parts that form the shape of the product, including moving mould, fixed mould and cavity, core, moulding rod and exhaust port.



Driven by the high-tech drive and application requirements of pillar industries, China's plastic moulds have formed a huge industrial chain, from upstream raw and auxiliary materials industry and processing, testing equipment to downstream machinery, automobiles, motorcycles, home appliances, electronic communications , Building materials, and other major application industries, plastic mould development is alive.
