Abstract

The utility model discloses a mold seizing and air trapping prevention device for a front mold core of a plastic mold. The mold seizing and air trapping prevention device for the front mold core of the plastic mold comprises a front mold and a rear mold. A cavity is formed between the front mold and the rear mold. The mold seizing and air trapping prevention device for the front mold core of the plastic mold is characterized in that an installation groove is arranged on the front mold, and a popup device which can eject a product out of the front mold to prevent the product from being seized at the front mold and prevent air trapping from occurring during mold opening is arranged in the installation groove. The mold seizing and air trapping prevention device for the front mold core of the plastic mold provided by the utility model overcomes the defects in the prior art and has the advantages that the structure is simple, the problem that the product is seized at the front mold of the plastic mold can be effectively solved, the exhaust effect is ensured to be good and the product is prevented from being burned or unfilled.

Description

Die anti-sticking mould, the anti-device of air that is stranded before a kind of plastic mould
Technical field
The utility model relates to the preceding die anti-sticking mould of a kind of plastic mould, the anti-device of air that is stranded.
Background technology
Existing plastic mould generally can select to be made in the back mould when doing the position of bone, if because be made in the phenomenon that front mould causes the card front mould easily under the deep situation of the position of bone.Existing plastic mould tends to change product or changes the generation that die joint is avoided this phenomenon for the phenomenon that prevents the front mould snap gauge.This change meeting brings many inconvenience and increases cost to production, and also has a big chunk product can not do the forced darker position of bone of front mould of doing under the situation of above adjustment.So the problem of front mould snap gauge still need solve.
The utility model content
The purpose of the utility model is in order to overcome weak point of the prior art; Provide a kind of simple in structure, can effectively solve plastic mould card front mould, guarantee good exhaust effect; Make product can not occur burning, die anti-sticking mould, the anti-device of air that is stranded before the plastic mould of starved phenomenon.
In order to achieve the above object, the utility model adopts following scheme:
Die anti-sticking mould, the anti-device of air that is stranded before a kind of plastic mould; Include front mould and back mould; Form a die cavity between described front mould and the back mould; It is characterized in that: on described front mould, be provided with mounting groove, prevent that product from snapping into front mould and producing the device for ejecting that is stranded gas thereby can product be ejected front mould when in described mounting groove, being provided with die sinking.
Die anti-sticking mould, the anti-device of air that is stranded is characterized in that described device for ejecting comprises the position of bone mold insert that is movably arranged in the said mounting groove before aforesaid a kind of plastic mould, between described position of bone mold insert and mounting groove bottom, are provided with elastic component.
Die anti-sticking mould, the anti-device of air that is stranded is characterized in that described elastic component is a spring before aforesaid a kind of plastic mould.
Die anti-sticking mould, the anti-device of air that is stranded is characterized in that described elastic component is a shell fragment before aforesaid a kind of plastic mould.
Die anti-sticking mould, the anti-device of air that is stranded is characterized in that described front mould is fixedly connected on the solid plate before aforesaid a kind of plastic mould, on described solid plate, are provided with runner plate, on described runner plate, are provided with fixed clamping plate.
Die anti-sticking mould, the anti-device of air that is stranded before aforesaid a kind of plastic mould is characterized in that described back mould is fixedly connected on the moving platen.
In sum, the utility model with respect to its beneficial effect of prior art is:
The utility model is simple in structure, can effectively solve plastic mould card front mould, guarantees good exhaust effect, makes product can not occur burning the starved phenomenon.
Description of drawings
Fig. 1 is the sketch map of the utility model;
Fig. 2 is the enlarged drawing at B place among Fig. 1;
Fig. 3 is the sketch map of front mould; Fig. 4 is the generalized section of A-A among Fig. 3;
The sketch map of device for ejecting work when Fig. 5 is die sinking.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is further described:
Die anti-sticking mould, the anti-device of air that is stranded before a kind of plastic mould shown in Fig. 1 to 5; Include front mould 1 and back mould 2; Form a die cavity 3 between described front mould 1 and the back mould 2; On described front mould 1, be provided with mounting groove 4, prevent that product from snapping into front mould 1 and producing the device for ejecting 5 that is stranded gas thereby can product be ejected front mould 1 when in described mounting groove 4, being provided with die sinking.
Device for ejecting 5 described in the utility model comprises the position of bone mold insert 51 that is movably arranged in the said mounting groove 4, between described position of bone mold insert 51 and mounting groove 4 bottoms, is provided with elastic component 52.
First kind of embodiment of the elastic component 52 described in the utility model is spring.Second kind of embodiment of the elastic component 52 described in the utility model is shell fragment.
Front mould 1 described in the utility model is fixedly connected on the solid plate 6, on described solid plate 6, is provided with runner plate 7, on described runner plate 7, is provided with fixed clamping plate 8.Described back mould 2 is fixedly connected on the moving platen 9.
Plastic mould one mould one chamber, front mould has the deep position of bone need do mold insert, but this structure is easy to when moulds open, and mould made progress away in front of the product position of bone partly was easy to, and caused the product card front mould.Do an elastic component in position of bone mold insert bottom, when front mould was opened, elastic component can be the action of position of bone mold insert to an ejection of die joint direction; So front mould position of bone part front mould disengaging auxiliary action that ejects the position of bone in addition fully; Make it can not block front mould, product is ejected smoothly, front mould can not occur snapping into; The product that much need do the front mould mold insert can use this structure, can solve the card front mould fully with the problem of being stranded gas.
