A plastic mould consists of two parts: the moving mould, which is mounted on the moving template of the injection moulding machine, and the fixed mould, which is mounted on the fixed template of the injection moulding machine. During injection moulding, the moving mould and the fixed mould are closed to form the pouring system and the cavity, and when the mould is opened, the moving mould and the fixed mould are separated in order to take out the plastic products.
Although the structure of the plastic mould may vary greatly due to the different plastic varieties and properties, the shape and structure of plastic products and the type of injection machine, the basic structure is the same.
