Water-cooled plastic product forming mold and forming method

Abstract

The invention relates to the technical field of plastic products, in particular to a water-cooled plastic product forming mold and method.The water-cooled plastic product forming mold comprises an upper mold body and a lower mold body, the outer wall of the top of the lower mold body is in movable contact with the outer wall of the bottom of the upper mold body, and a containing groove is formed in the outer wall of the top of the lower mold body; an injection molding opening is formed in the middle of the outer wall of the top of the upper mold, and a mold core is movably inserted into the lower mold. The water-cooling tank has the beneficial effects that the water-cooling tank is divided into a plurality of cells by the partition plates in the water-cooling tank, and the height of the cells is the same as that of the mold core, so that after the cells are filled with cold water, the outer surface of the mold core can be uniformly cooled, and the influence on the appearance quality of a product due to non-uniform cooling of each part during molding of the plastic product is avoided; correspondingly, the height of the water cooling tank is the same as that of the mold core, and the whole outer wall of the mold core can fully exchange heat with cold water in the water cooling tank, so that a product in the mold core can be uniformly cooled.
