Abstract

The invention discloses a quick release device for an air cap used in the production of injection molds, and relates to the technical field of injection molds. The invention comprises a fixed mold fixed plate, a movable mold fixed plate, a fixed mold base, a movable mold base, an upper mold core, a lower mold core and an air cap device. The present invention aims at the problems of difficult demoulding between the existing deep-cavity products and the injection mold, and a high rate of defective products. The air cap device composed of the air pipe, the third air pipe and the air pump, after injection molding, the air pump starts to deliver gas to the first air pipe, and the first motor drives the first air pipe to rotate, so that the first rotating rod is in the first sliding position. Sliding in the groove, the gas blows from the first air delivery hole to the side wall of the deep cavity product; thus loosening the side contact surface between the deep cavity product and the lower mold core; the first ejector plate rotates accordingly, making the deep cavity product The top contact surface with the lower mold core is loose, which improves the demoulding efficiency of deep cavity products.

Description

technical field [0001] The invention belongs to the technical field of injection molds, and in particular relates to an air cap rapid demoulding device for production of injection molds. Background technique [0002] Injection molding is a common method for producing injection molded products. Specifically, it refers to injecting heated and melted materials into the mold cavity under high pressure, and after cooling and solidifying, molded products are obtained. In the process of injection molding, in order to make the product fall out of the mold cavity smoothly after molding, an ejector mechanism is usually used to push the product out. In injection molding products, container products such as barrels, boxes, and boxes with closed walls, bottoms, and cavity depths greater than five times the wall thickness are called deep cavity products, such as battery shells; the gap between the product and the mold core The large covering force, combined with the effect of stickiness ...
