working principle
In injection molding, plastic particles are heated, melted, and plasticized under the action of a screw, and enter the mold cavity through a hot runner. The cavity formed by the splicing of mold kernels gives the plastic screw a specific shape, and the cooling system cools the cavity to solidify the plastic into shape. When opening the mold, the lower mold moves downwards with the mold core, and the mold core block moves outward under the guidance to open the mold cavity. Then, the screw is pushed out of the mold through the ejector mechanism such as the ejector pin.
