Rapid die changing mould

Abstract

The invention discloses a rapid die changing mould. The rapid die changing mould is characterized in that a front die core bottom plate is arranged on a front die core, the front die core is flexibly arranged on a rear die core, and the rear die core is arranged on a rear die core bottom plate; a surface needle plate is fixedly arranged on a bottom needle plate, the surface needle plate is provided with a thimble and a resetting rod, the thimble passes through the rear die core bottom plate and stretches into a die cavity of the rear die core, and the resetting rod is sleeved with a resetting spring; the resetting rod passes through the rear die core bottom plate and is inserted into the rear die core, and the front die core bottom plate, the front die core, the rear die core, the rear die core bottom plate, the surface needle plate and a bottom needle plate are connected into a whole; a die frame B plate is arranged on a die leg, the die leg is arranged on a bottom plate, a hollow cavity is formed in the die leg, and the resetting rod, the resetting spring, the thimble, the surface needle plate and the bottom needle plate are placed in the hollow cavity; and the front die core bottom plate and a die frame A are arranged in a demountable manner, and the rear die core bottom plate and the die frame B plate are arranged in the demountable manner. The rapid die changing mould provided by the invention can take the whole inner die structure out in one-step operation to realize rapid die changing, and the injection molding production efficiency is improved.

Description

technical field [0001] The invention relates to an injection mold, in particular to a quick mold change mold. Background technique [0002] Injection molds in the prior art generally include a mold base A plate, a front mold core base plate, a front mold core, a rear mold core, a rear mold core base plate, a reset lever, a reset spring, a thimble, a face needle plate, a bottom needle plate, and a mold frame B. Plate, mold foot and bottom plate; the bottom plate of the front mold core is installed on the mold base A plate, and the front mold core is installed on the mold base; the thimble and reset lever are installed on the bottom needle plate, and the thimble passes through the bottom plate of the rear mold core and extends into the rear In the mold cavity of the mold core, the return spring is sleeved on the reset rod, and the reset rod passes through the bottom plate of the rear mold core and extends into the rear mold core; the rear mold core and the bottom plate of the ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, in the mold of the prior art, its inner mold structure and the mold base are integrated, and a pair of inner mold structures corresponds to a pair of mold bases, one-to-one correspondence. Both the front mold core and the rear mold core are installed on the mold base, and the inner mold structure and the mold base must be replaced as a whole. That is, when different products are injected, the inner mold structure and the mold base must be replaced at the same time. The replacement of the inner mold structure affects the production efficiency of injection molding
