Demolding ejecting device of double-color mold and demolding method of demolding ejecting device

Abstract

The invention discloses a demolding ejecting device of a double-color mold. The demolding ejecting device comprises a base plate, a rotating shaft, first sliding block cores, second sliding block cores, a first sliding block sleeve, a second sliding block sleeve, a front shifting block and a back shifting block; the base plate comprises a front-side plate surface, a back-side plate surface, a left-side plate surface, a right-side plate surface, a bottom plate surface and a top plate surface; the rotating shaft is arranged on the bottom plate surface; the first sliding block cores and the second sliding block cores are arranged on the top plate surface; the first sliding block sleeve is mounted on the first sliding block cores; the second sliding block sleeve is mounted on the second sliding block cores; a first demolding shaft and a first positioning shaft are arranged on the first sliding block sleeve; a second positioning shaft and a second demolding shaft are arranged on the secondsliding block sleeve; and the front shifting block and the back shifting block are arranged on one side of the left-side plate surface respectively. By the aid of the demolding ejecting device of thedouble-color mold, products can be ejected directly by the sliding block sleeves, demolding can be completed, ejecting pins can be saved, the mold structure can be optimized, and the mold manufacturing cost can be reduced effectively.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a demoulding and ejecting device for a two-color mold and a demoulding method thereof. Background technique [0002] Double-material injection mold is an injection mold that molds hard plastic and soft plastic into double-material composite injection products through double-material injection molding machine. Usually, double-material injection mold is also called two-color mold, and double-material composite injection molding is called two-color molding. Double-material composite injection products are called double-color products. [0003] The existing two-color mold adopts two-color machine injection molding two-color products. When in use, the fixed mold of the two-color mold is installed at the fixed workbench of the two-color machine, and the movable mold of the two-color mold is fixed at the rotating movable workbench of the two-color machine. When working, The rot...

AI Technical Summary

Problems solved by technology

Because the two-component machine is expensive, the operating cost is high, and the rotating movable table carries the entire movable mold, the rotation speed is slow, the efficiency is low, and the mold structure is complicated. Therefore, the existing technology has the problems and shortcomings of high cost and low efficiency. The injection mold industry There is an urgent need for a stripping and ejecting device that can simplify the structure of the two-color mold
