Spring-reset plastic molding mould for pushing and retracting stripping by forced deformation of support group

Abstract

The invention discloses a spring-reset plastic molding mould for pushing and retracting stripping by forced deformation of a support group. The spring-reset plastic forming mould comprises a guide column hole, a guide column, a fixed die plate, a fixed die holder, a water inlet hole and a molding stripping device, wherein the molding stripping device is positioned on the end face of the lower sideof the fixed die holder and is in fit connection with the fixed die seat. A special-shaped block in the inner part is pushed upwards by a movable column at the lower part, and a regulating bracket onthe upper part moves to deform, so that one side of a pushing column in the inner part is pushed out slightly, the other side of the pushing column is retracted into and matched with the inner part of an unloading bracket, and therefore demoulding gradient is formed. Forced pushing by a rod body is not adopted, so that unloading is more stable, and the safety of finished products is ensured. A permanent magnet repelling a magnetic block is arranged in the inner part of a sliding block and is matched with the magnetic block, and the sliding block is matched with a sliding groove in a sliding mode, so that a block body can move stably along an arc-shaped column, the pushing column rising by forced pushing can be more smooth and stable, and difficult push-out due to aging cannot occur.

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.
