Description

A kind of demoulding cant

Technical field

The utility model relates to the mould manufacturing, relates in particular to a kind of demoulding cant.

Background technology

Cant is a kind of mould emptier of mould manufacturing field, a kind of mold releasability mechanism that particularly often uses during the inner fluted or endoporus of product.In die industry, use various forms of cants at present, its stripping means is that cant is when ejecting, the cant top skids off from the groove of product inwall or endoporus as mold cores, thereby reach the purpose of the demoulding, but, if run into the inboard wall groove of product or endoporus when dark, because it is interior to tightening force that product injection moulding produces, when perhaps the ejection resistance of inboard wall groove or endoporus was big, after the cant pushing tow, product still can adhere to the cant tip motions, make the demoulding can not be complete, cant loses demoulding effect, and therefore, the stripping result of prior art is bad.

Summary of the invention

The demoulding cant that provides a kind of stripping result good is provided the purpose of this utility model, to overcome the incomplete shortcoming of product stripping in the prior art.

The technical scheme that the utility model adopted is, this demoulding cant comprises " 7 " font cant plate, and this cant plate top is horizontal push pedal, it is characterized in that: be provided with through hole in the described horizontal push pedal, also comprise second push pedal, described through hole is inserted in described second push pedal;

Described through hole is along the horizontal direction break-through of horizontal push pedal;

Described second push pedal is a bifoldable plate, and a flanging of this bifoldable plate inserts described through hole;

The perpendicular type bifoldable plate that described bifoldable plate is structure as a whole;

Two flangings of described bifoldable plate are vertical mutually, between by assigning pin to connect as one.

The beneficial effects of the utility model are: in the utility model, comprise the cant plate and second push pedal, cant plate ejection product wherein, product is deviate from from mould, carry out the demoulding first time, simultaneously, because under the effect of mould angle pin, the horizontal flanging of second push pedal can relatively pass through the stripping direction motion of the through hole of cant plate to the product inwall, stops product adhesion cant plate, realize the demoulding for the second time, product is broken away from from mould fully, solved that product still can adhere to the cant tip motions in the prior art, the incomplete problem of the demoulding, therefore, the utility model stripping result is good.

In the utility model, (vertically) bifoldable plate is adopted in second push pedal, in the process of ejection product stripping, can guarantee that the cant plate and second push pedal are synchronized with the movement, under an ejection action, realize the complete demoulding, simple to operate, overall structure is simple, compact, has improved practicality of the present utility model.

In the utility model, assign pin between two flangings, in use, can change, use the horizontal flanging of different length as required, further improved practicality of the present utility model.

The specific embodiment

With embodiment the utility model is described in further detail with reference to the accompanying drawings below:

Embodiment 1

According to illustrated in figures 1 and 2, the utility model comprises the cant plate 1 and second push pedal 2, and cant plate 1 is " 7 " font, comprises the horizontal push pedal 11 that is positioned at the top and along the through hole 12 of the horizontal direction break-through of horizontal push pedal 11, wherein, and horizontal push pedal 11 pushing tow products 3.

As shown in Figure 1, second push pedal 2 is the bifoldable plate structure, and this bifoldable plate comprises horizontal flanging 21 and vertical flanging 22, and the through hole 12 of cant plate 1 is passed in the outer end of horizontal flanging 21, and pin 20 is assigned in the junction of horizontal flanging 21 and vertical flanging 22.

As shown in Figure 3, with the utility model mould 4 of packing into, upper plate 51 is replaced in the bottom of cant plate 1, and vertically the bottom of flanging 22 is passed top board 51 and replaced lower roof plate 52, and upper plate 51 pastes mutually with lower roof plate 52, is provided with below upper plate 51, the lower roof plate 52 and injects top rod 6.

As shown in Figure 4, mould 4 is provided with one at horizontal flanging 21 places of second push pedal 2 and escapes dead slot 40, this is set escapes dead slot 40 horizontal flanging 21 can be moved up and down.

Use knockout course of the present utility model as follows:

During the demoulding, as shown in Figure 5, ejection injection top rod 6, upper plate 51 and lower roof plate 52 are moved upward, and further drive cant plate 1 and second push pedal 2 moves upward, cant plate 1 moves upward along the angle pin of mould 4, promote product 3 and break away from mould 4, realize the demoulding for the first time; Since the effect of mould 4 angle pins, in the process that cant plate 1 moves upward, the horizontal flanging 21 of second push pedal 2, relatively, the through hole 12 by cant plate 1 moves prevention product 3 adhesion cant plates 1 to the stripping direction of product 3 inwalls, make product 3 break away from cant plate 1, realize the demoulding for the second time.So, product 3 demoulding fully from mould 4.

In the present embodiment, be directed to different product 3, can change, use the horizontal flanging 21 of different length as required, strengthened practicality of the present utility model by loading and unloading pin 20.

Embodiment 2

According to shown in Figure 5, the difference of present embodiment and embodiment 1 is: in the present embodiment, the perpendicular type bifoldable plate that second push pedal 8 is structure as a whole, the horizontal flanging of this bifoldable plate inserts in the through hole 12 of cant plate 1.

Other structure and knockout course and the foregoing description are described same or similar, repeat no more herein.

In above-mentioned all embodiment, the through hole 12 of cant plate 1 is along the horizontal direction break-through of horizontal push pedal 11, in fact can make through hole 12 have certain oblique angle, and, the structure of second push pedal 2 can adopt other distressed structure, for example arc-shaped transition etc. is adopted in the bending place, main points of the present utility model are that passing through hole 12 by second push pedal 2 realizes the demoulding for the second time, according to the above, can not need to pay creative work to those skilled in the art can implement, and repeats no more herein.
