Description

Forced pre-reset anti-collision die structure

Technical Field

The invention relates to the technical field of dies, in particular to a forced pre-reset anti-collision die structure.

Background

Some goods are for the needs of structure, the mould is in the compound die, the guide pillar inserts the downthehole that removes the seat to one side, the messenger removes the seat and resets, constitute the shaping chamber, be convenient for follow-up to the shaping intracavity raw materials of moulding plastics, if remove the seat and fail in time to reset this moment, the guide pillar will be hit to one side and remove the seat, the guide pillar that then inclines hits absolutely lightly, heavy then remove the seat and hit badly for the unable normal use of mould, and still need carry out the drawing of patterns after the shaping, work efficiency is low, for this reason, we release a force anticollision mould structure that resets in advance.

Disclosure of Invention

The invention aims to provide a forced pre-reset anti-collision mould structure to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a force anticollision mould structure that resets in advance, includes base and upper die base, be equipped with the die holder in the upper end recess of base, the die holder includes that bilateral symmetry sets up the removal seat in base upper end recess, controls two sets ofly remove to be connected with the spring between the seat, controls two sets of the upper end inboard of removing the seat all is equipped with into die cavity recess, and is two sets of die cavity recess combination is into the die cavity, the protruding platform both sides of upper die base lower extreme are equipped with oblique guide pillar, the lower extreme both sides of upper die base are equipped with the release link, the upper end outside of removing the seat is equipped with the slope open slot that is used for inserting the release link, the upper end of removing the seat still is equipped with.

Preferably, a transverse sliding rail is arranged in the groove at the upper end of the base, and the sliding groove at the bottom of the movable seat is connected to the transverse sliding rail in a sliding manner.

Preferably, two ends of the spring are correspondingly inserted into positioning round holes on the inner sides of the left and right groups of moving seats.

Preferably, the sliding connection bulges on the two sides of the upper die base are movably connected with rollers through pin shafts, and the rollers are in sliding connection with vertical sliding grooves in the inner side wall of the support.

Preferably, the two sides of the lower end of the support are connected to the upper end of the base, the top of the support is connected with a supporting plate, a hydraulic cylinder is arranged at the top of the supporting plate, and a piston rod of the output end of the hydraulic cylinder penetrates through the supporting plate and is connected to the middle of the upper end of the upper die base.

Compared with the prior art, the invention has the beneficial effects that: under the action of the elastic force of the spring, the two groups of moving seats move towards the two ends of the transverse sliding rail along the transverse sliding rail until the moving seats are contacted with the side wall of the groove at the upper end of the base, so that the inclined open slot is just positioned under the reset rod;

a piston rod at the output end of the hydraulic cylinder extends out to enable the upper die base to move downwards, and at the moment, as the sliding connection bulges at the two sides of the upper die base are movably connected with the roller through the pin shaft, and the roller is in sliding connection with the vertical sliding groove on the inner side wall of the bracket, the deviation in the horizontal direction can not occur in the downward moving process of the upper die base, and the resetting rod can be accurately inserted into the inclined open slot;

the upper die base continuously moves downwards, the lower end of the reset rod is just contacted with the inclined open slot, then the lower end of the reset rod enters the inclined open slot, and the lower end of the reset rod props against an inclined surface on the inner side of the inclined open slot, so that when the reset rod moves downwards, the reset rod can push the moving base to move inwards along the transverse sliding rail;

in the process that the reset rod pushes the movable seat to continuously move inwards along the transverse sliding rail, the lower end of the inclined guide post is inserted into the inclined hole, at the moment, the upper die seat, the reset rod and the inclined guide post integrally move downwards, and then under the condition that the reset rod pushes the movable seat to continuously move inwards along the transverse sliding rail until the inclined guide post is completely inserted into the inclined hole, at the moment, the inner sides of the two groups of movable seats just contact to enable the two groups of forming cavity grooves to be combined into a forming cavity, so that the die assembly of the upper die seat and the lower die seat is completed, and the upper die seat enables the forming cavity to be sealed;

in the process that the inclined guide post is inserted into the inclined hole, the reset rod continuously pushes the movable seat to move inwards along the transverse slide rail, so that the phenomenon that the inclined guide post is broken due to impact generated when the inclined guide post is inserted into the inclined hole to cause that the die cannot be normally used is avoided;

after the shaping, the piston rod of pneumatic cylinder output contracts back, make the upper die base rebound, when the lower extreme of release link left the slope open slot gradually, under the spring action of spring, make two sets of removal seats move to its both ends along transverse sliding rail, simultaneously, the lower extreme of oblique guide pillar also leaves the inclined hole gradually, leave the inclined hole until oblique guide pillar takes precedence, the release link also leaves the slope open slot afterwards, under the spring action of spring, make two sets of removal seats move to its both ends along transverse sliding rail, remove the upper end recess lateral wall contact of seat and base, thus, two sets of removal seats separate the back, the formed part has also broken away from the shaping chamber, the drawing of patterns has been accomplished.
