Structural parts of injection mould

It refers to the structure of the mold components, including: guidance, demoulding, core-pulling and classification of the various parts. Such as the front and rear plywood, front and rear buckle formwork, bearing plate, bearing column, guide column, Demoulding Plate, demoulding rod and return rod, etc. .

1. Guide parts, in order to ensure that the dynamic mold and the fixed mold in the mold can be accurate alignment, must be set in the mold guide parts. In the injection mold, four groups of guide posts and guide sleeves are usually used to form the guide parts. Sometimes, the inner and outer conical surfaces are set on the moving mold and the fixed mold respectively to assist the positioning.

2. A push mechanism is required to push or pull the plastic product and its condensate in the runner during the opening process. The fixed plate and the push plate are pushed out to clamp the push rod. A reset rod is generally fixed in the push rod, and the reset rod makes the push plate reset when the movable and fixed mould is closed.

3. Some plastic products with side concave or side hole of side core-pulling mechanism must be divided laterally before being pushed out, and the side core-pulling mechanism should be set in the mould.
