Abstract

A mold structure capable of forcedly releasing a mold comprises a female mold plate. A female mold core is arranged in the female mold plate, a male mold core is disposed below the female mold core and arranged in a male mold plate, the female mold plate and the male mold plate are connected by an opening and closing device when the mold is released, a cushion plate is disposed below the male mold plate, an insert is fixed onto the cushion plate, a draw bar is further arranged on the cushion plate, a spring matches with the draw bar so that the cushion plate is connected with the male mold plate, a foot pad is disposed below the cushion plate, and a plurality of ejector plates are arranged in the foot pad and used for fixing ejector pins. By the aid of the mold structure, the mold of barbs of products can be safely and conveniently released.

Description

Mould structure

Technical field

The utility model relates to a kind of mould structure, but and is particularly related to a kind of mould structure of forced stripper mechanism.

Background technology

In the last few years, along with being widely used of plastic product, the plastics industry had had the development of advancing by leaps and bounds, and had become indispensable part in the present industrial structure.As everyone knows; Produce plastic product and will design corresponding mould structure, yet the internal structure of some plastic product is complicated unavoidably, like overhead kick treatment systems such as slide block, taper pins; Desire wants pushing-off product must make finished product production elastic deformation; Produce the space that elastic deformation but must be out of shape, yet in the existing mould structure, eject at finished product and to go to toward can not giving the corresponding deformation space of finished product; Just finished product can't be ejected, and also just can not produce such as the finished product that overhead kicks such as slide block, taper pin are arranged.

By on can know, in fact be necessary to provide a kind of mould structure that is ejected the previous conviction forced stripper mechanism at finished product.

The utility model content

But the main purpose of the utility model is to provide a kind of mould structure of forced stripper mechanism.

For reaching above-mentioned purpose, but the utility model provides a kind of mould structure of forced stripper mechanism, and it comprises a caster, is provided with a mother module core in this caster; The below of mother module core is provided with a male model benevolence, and said male model benevolence is arranged in the male model plate, and caster and male model plate are connected through a derailing switch when the demoulding; The below of male model plate is provided with a backing plate, is fixed with one on the backing plate and goes into son, and also be provided with a pull bar on the backing plate; And have a spring to cooperate pull bar that backing plate is connected with the male model plate, the below of backing plate is provided with foot pad, is provided with some top boards in this foot pad; In order to fixing thimble,, can safe ready ground realize the smooth demoulding of product overhead kick through above-mentioned mould structure.

Compared to prior art, but the mould structure of the forced stripper mechanism that the utility model provides is not only realized the smooth demoulding of product overhead kick but also simple in structure, cheap for manufacturing cost, workable, safe and reliable.

Description of drawings

Fig. 1 is the generalized section of the utility model mould structure;

Fig. 2 is the demoulding step sketch map of the utility model mould structure.

The specific embodiment

See also shown in Figure 1; Be the generalized section of the utility model mould structure, the utility model mould structure comprises a caster 10, and there is a fixed head 900 top of this caster 10; And be provided with a mother module core 101 in this caster 10; Mother module core 101 belows are provided with a male model benevolence 201, and this male model benevolence 201 is arranged in the male model plate 20, and said caster 10 and male model plate 20 when the demoulding through being connected with shutter 3; This shutter is used to be implemented in the male model of die sinking for the first time plate 20 and caster 10, and the below of male model plate 20 is provided with a backing plate 30.Be fixed with one on this backing plate 30 and go into son 301, this child 301 arrives in the male model benevolence 201 through male model plate 20, and also is provided with a pull bar 40 on the said backing plate 30; And there is a spring 50 to cooperate pull bar 40 that backing plate 30 is connected with male model plate 20; Backing plate 30 belows are provided with foot pad 60, are provided with some top boards 70 in this foot pad 60, in order to fixing thimble 701; Foot pad 60 is fixed on the bottom plate 80 of below, and caster 10 is connected through an island master 90 with male model plate 20 and backing plate 30 in addition.

See also shown in Figure 2ly, be the demoulding step sketch map of the utility model mould structure, during the demoulding; Shutter 3 is held male model plates 20 and casters 10, so that male model plate 20 is connected with caster 10 is motionless, under self elastic force effect of spring 50; Backing plate 30 drives son 301 motions, accomplishes die sinking for the first time, when backing plate 30 drives son 301 and breaks away from finished product trip 7 fully; The binding force of male model plate 20 and caster 10 customer service shutter 3 under the active force of moulding board is accomplished die sinking for the second time, can see that the son 301 of coming in and going out breaks away from finished product trip 7 fully two this moments after; Then abdicated deformation space to finished product, worked as male model plate 20 then and move downward certain Chengdu, miss is 701 pushing-off products truly; Then trip 7 deforms under the extruding of male model benevolence 201, and forced stripper mechanism is accomplished smoothly.

The mould structure that the utility model provided is realized the order die sinking of three template dies with two template dies; Just between male model plate and foot pad, increase a backing plate; Then through the commonly used part lower link bar of three template dies and shutter control die sinking in proper order, compared with prior art the utility model is not only realized the smooth demoulding of product overhead kick but also is had simple in structure, cheap for manufacturing cost, workable, safe and reliable advantage.

Claims
