Abstract

The invention provides a demolding device and a demolding method, which belong to the technical field of injection molding and are used for demolding an injection workpiece in a mold. The demolding device comprises a base, a stop block, a driving assembly and an ejector pin, wherein the base is arranged on one side of the mold and can move up and down relative to the mold; the stop block is arranged between the mold and the base, is fixedly connected with the base and is provided with a through hole, and the size of the through hole is smaller than that of the end, which is in contact with the stop block, of the injection workpiece; the driving assembly is fixedly connected with one end, outside a cavity of the mold, of an insert pin of the mold, the insert pin can penetrate through the through hole in the stop block to stretch into the cavity of the mold and can horizontally move relative to the base; the ejector pin is fixedly connected with the bottom of the base. With the demolding device and the demolding method, the molded injection workpiece can be successfully separated from the mold, and the surface damage or deformation of the injection workpiece can be avoided.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a demoulding device and a demoulding method. Background technique [0002] The demoulding method of the injection molded workpiece is generally to separate the upper and lower mold cores of the mold, or to increase the slider through the lower mold core to move left and right, back and forth by the inclined guide column, and then directly eject the injection molded workpiece from the cavity through the ejector pin of the lower mold. out to achieve the purpose of demoulding the injection molded workpiece. [0003] The cavity of the original mold for processing fully threaded parts and such injection molded workpieces with particularly high appearance requirements is composed of upper mold core, lower mold core and insert pins. The thimble of the lower mold is arranged on the side of the full circle of screw teeth of this type of injection molding workpiece, and the thim...
