The Mould Composition Of Plastic Injection Mold
Aug 17, 2017

The injection mold is composed of two parts, the dynamic mode and the fixed die, the movable mould is installed on the moving template of the injection molding machine, and the fixed die is installed on the fixing formwork of the injection moulding machine. During injection molding, the casting system and the mold cavity are formed by closing the die and fixed die, and the mould is separated to remove the plastic products.

Although the structure of the mould may be changeable due to the variety and properties of plastic, the shape and structure of plastic products and the type of injection machine, the basic structure is consistent. The mold is mainly composed of pouring system, thermostat system, forming parts and structural parts. wherein the gating system and the molded parts are directly contacting with the plastic, and vary with the plastic and the products, is the most complex in the plastic mold, the change is the biggest, requires the processing smoothness and the highest precision part.

The pouring system refers to the flow passage part of the plastic from the nozzle into the cavity, including the main channel, the cold material hole, the Distributary channel and the gate. The forming part is a kind of various parts which form the shape of the product, including the movable mode, the fixed mode and the cavity, the core, the forming rod and the exhaust port.
