What is the role of injection mould? What are the components? What is the role of each? The structural composition of the injection moulding mould can be divided into the following parts: moulding part, mould clamping guide part, product ejection part, core extraction part, heating and cooling part of the mould body, supporting part of the mould body and pouring melt channel, row Stomata etc.

(1) moulding part. That is, after the mould is assembled and closed, the cavity part of the plastic product is directly formed as a component part, such as a punch, a concave mould, a core, a rod, or an insert.
(2) Clamping guide part. It is a part that is set up so that the center axis can be correctly aligned when the moving and fixed moulds are closed. There are guide columns, guide hole sleeves or tapered cones.
(3) Product launch part. It is the parts used to push the moulded injection products out of the mould cavity, such as ejector rods, fixed plates, push plates and pads.
(4) The core extraction part. When injection moulding plastic products with pits or side holes are demoulded, the core mechanism parts used for forming pits and side holes are first extracted, such as frequently used oblique guide posts,
Core pulling mechanism such as slider and bending pin.
(5) The heating and cooling part of the mould body. Refers to the control system that adapts to the temperature of the injection moulding process of plastic products, such as resistance heating plates, rods and their electronic control components; the cooling part uses circulating cooling water pipes.
(6) The supporting part of the mould body. Refers to the auxiliary parts to ensure that the mould body can work correctly, such as moving and fixed mould backing plates, positioning rings, lifting rings and various fastening screws.
(7) Pouring molten material channel. Refers to the flow channel that can lead the molten material injected through the nozzle to the cavity of the forming mould. It can usually be divided into a main channel, a split channel, a bushing (gate), and a cold material tank.
(8) Exhaust holes. Refers to the part that can discharge the air in the mould cavity. Generally, small products do not need special vents, and the air in the cavity can be discharged from the gap of each fitting; for large injection products, the vents must be provided.
