Structural parts of injection molds include various parts of guide, release, core extraction and parting. Such as front and rear splints, front and rear buckle templates, pressure plates, pressure columns, guide columns, de-templates, release rods and return rods. 1. Guide parts: In order to ensure that the moving and fixed molds can be accurately paired in the die, the guide parts must be set in the mold. In the injection molding mold is usually used four sets of guide posts and guide sleeves to form the guide parts, and sometimes on the dynamic and fixed molds to set each other’s internal and outer cones to assist in positioning. 2. Launching agency: In the mold opening process, it is necessary to introduce the plastic products and their condensation in the runner to push out or pull out. Introduce a retaining plate and push plate to hold the pushrod. In the pushrod is generally fixed with a reset rod, the reset lever in the movement, fixed die-fitting mold to reset the push plate. 3. Side pumping mechanism: some plastic products with side concave or side holes, before being pushed out must be side-by-side profile, pull out the side core can be smoothly released, at this time need to set up side pumping mechanism in the mold.
