Abstract
The invention discloses a mould clamping prevention mechanism for a front mould, which comprises a front mould and a rear mould. A cavity is formed between the front mould and the rear mould. The mould clamping prevention mechanism is characterized in that an installation groove is positioned on the front mould, and a popping device is arranged in the installation groove. The popping device can push products out of the front mould to prevent products from being clamped on the front mould to generate gas trap effect. The mould clamping prevention mechanism for the front mould aims at overcoming defects in the prior art, is simple in structure, can effectively resolve the problem that plastic moulds are prone to be clamped on the front mould, guarantees good air exhaust effect and prevents products from being burned and lacking glue.
Description
Technical field
The present invention relates to a kind of front mould anti-clamping mould mechanism.
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.
Summary of the invention
The objective of the invention is provides a kind of simple in structure in order to overcome weak point of the prior art, can effectively solve plastic mould card front mould, guarantees good exhaust effect, makes product the front mould anti-clamping mould mechanism of starved phenomenon can not occur burning.
In order to achieve the above object, the present invention adopts following scheme:
A kind of front mould anti-clamping mould mechanism; 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 the device for ejecting of front mould thereby can product be ejected front mould when in described mounting groove, being provided with die sinking.
Aforesaid a kind of front mould anti-clamping mould mechanism is characterized in that described device for ejecting comprises the position of bone mold insert that is movably arranged in the said mounting groove, between described position of bone mold insert and mounting groove bottom, is provided with elastic component.
Aforesaid a kind of front mould anti-clamping mould mechanism is characterized in that described elastic component is a spring.
Aforesaid a kind of front mould anti-clamping mould mechanism is characterized in that described elastic component is a shell fragment.
Aforesaid a kind of front mould anti-clamping mould mechanism is characterized in that described front mould is fixedly connected on the solid plate, is connected with fixed clamping plate on described solid plate.
Aforesaid a kind of front mould anti-clamping mould mechanism is characterized in that between described solid plate and fixed clamping plate, being provided with runner plate.
Aforesaid a kind of front mould anti-clamping mould mechanism is characterized in that described back mould is fixedly connected on the moving platen.
In sum, the present invention with respect to its beneficial effect of prior art is:
The present invention 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 a sketch map of the present invention;
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 present invention is further described:
A kind of front mould anti-clamping mould mechanism 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 present invention 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 present invention is spring.Second kind of embodiment of the elastic component 52 described in the present invention is shell fragment.
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.
