Spring-return plastic molding die with force deformation, top shrinkage and stripping of support group

Abstract

The invention discloses a spring-return plastic molding mold which is deformed by force, deforms and ejects materials by a spring, and its structure includes: guide post holes, guide posts, fixed templates, fixed mold seats, water inlet holes, forming and stripping devices, and forming and stripping devices. The material device is located on the lower end surface of the fixed mold seat, and the two are fit and connected. The inner special-shaped block is pushed upward through the movable column below, and the adjustment frame above is displaced and deformed, so that one side of the inner movable column is pushed upward slightly, and the other side is pushed upward. One side is retracted to match the inside of the unloading rack, thereby forming a stripping slope, without forceful jacking by the rod body, which can make the unloading more stable and ensure the safety of the finished product. The magnetic blocks are repelled by permanent magnets to cooperate with the magnetic blocks, and through the sliding cooperation between the sliding block and the chute, the block can be displaced stably along the arc-shaped column, so that the force can push the lifting column It can be smoother and more stable, and there will be no difficulty in ejecting due to aging.

Description

technical field [0001] The invention relates to the field of plastic moulds, in particular to a spring-returning plastic molding mould, which is deformed and ejected by a support group under force. Background technique [0002] The current molding die device usually uses two rods to push the gears and rollers on one side with racks of different heights to engage with each other, so that the rods are pushed out of different heights to achieve the release slope, so as to complete Plastic parts come off the film, but in this way it is easy to cause: [0003] During the demoulding work, the plastic parts attached to the mold core are simultaneously pushed out through two rods of different heights, which will turn the finished product out and drop it, increasing the probability of damage to the finished product, and at the same time, it is easy to make the plastic part on the top When moving, the finished product is scratched due to the viscosity of the plastic parts.

[0002] The current molding die device usually uses two rods to push the gears and rollers on one side with racks of different heights to engage with each other, so that the rods are pushed out of different heights to achieve the release slope, so as to complete Plastic parts come off the film, but in this way it is easy to cause:

[0003] During the demoulding work, the plastic parts attached to the mold core are simultaneously pushed out through two rods of different heights, which will turn the finished product out and drop it, increasing the probability of damage to the finished product, and at the same time, it is easy to make the plastic part on the top When moving, the finished product is scratched due to the viscosity of the plastic parts. At the same time, with the gear meshing activities, the internal gears will age after a long time of work, which makes the ejection difficult and increases the labor intensity of the staff.
