Be applicable to the mould of production safety air cell covering
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of mould for the production of the airbag cover on vehicle steering.
Background technology
The mould of existing production safety air cell covering, master mold carries out the demoulding after removing, and at least needs the action of more than three times, eject often and complicated operation, cause unitary mould volume larger, cost increases greatly, and after die sinking, need hand adaptation pickup, reduce production efficiency.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of structure simple, the mould of the production safety air cell covering of the demoulding can be completed for twice.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
Be applicable to the mould of production safety air cell covering, comprise: upper die and lower die and the die cavity be positioned between the two, described patrix is from top to bottom provided with successively: upper mounted plate, hot runner manifold, caster, arranges a mother module core in described caster; Described counterdie is provided with from the bottom to top successively: oil hydraulic cylinder, be provided with the bottom plate of cooling water pipe, be provided with the male template of male die core, form spatial accommodation between described bottom plate and male template and periphery is supported by mould pin, in described spatial accommodation, be provided with support column, ejector retainner plate guide pillar, ejector retainner plate, thimble and push rod; Described push rod and thimble all stretch in die cavity, on push rod, cover has the elastic component outwards ejected by push rod, the end of push rod is connected with a product cover core rod, thimble by oil hydraulic cylinder driving and end is positioned at product cover core rod, described product cover core rod is formed for thimble through thus make the through-hole structure of product stripping.
Aforementioned caster is provided with guide pillar, described male template is formed with the guide frame coordinated with guide pillar.
Aforementioned push rod is a pair, parallel arranged and through same push rod bundle block.
Aforementioned elastic parts is helical spring.
Aforementioned thimble is two, is divided into the both sides of push rod.
Usefulness of the present invention is: mould of the present invention, and after master mold is removed, push rod outwards ejects by the elastic force that automatically resets of elastic component, realizes once ejecting, and product has distortion simultaneously; Oil hydraulic cylinder drives thimble to eject subsequently, makes product stripping, ejects can realize the demoulding, quickness and high efficiency through twice, and without the need to product of manually taking.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
See Fig. 1, the mould being applicable to production safety air cell covering of the present invention, comprising: upper die and lower die and the die cavity be positioned between the two.Particularly, patrix is from top to bottom provided with successively: upper mounted plate 1, hot runner manifold 2, caster 3, arranges a mother module core 4 in caster 3; Counterdie is provided with from the bottom to top successively: oil hydraulic cylinder 5, be provided with the bottom plate 7 of cooling water pipe 6, be provided with the male template 9 of male die core 8.Form spatial accommodation between bottom plate 7 and male template 9 and periphery is supported by mould pin 10, as shown in Figure 1, in spatial accommodation, be provided with support column 11, ejector retainner plate guide pillar 12, ejector retainner plate 13, thimble 14 and push rod 15; Wherein, push rod 15 and thimble 14 are the core components for being ejected by product 21, and end is all stretched in die cavity.In order to realize automatically, ejecting product 21 efficiently, on push rod 15, cover has the elastic component 16 push rod 15 outwards being ejected (namely once ejecting), be preferably helical spring, the end of push rod 15 is connected with a product cover core rod 17, thimble 14 by oil hydraulic cylinder 5 driving and end is positioned at product cover core rod 17, product cover core rod 17 is formed for thimble 14 through thus make the through-hole structure of product 21 demoulding (i.e. Double-ejection).
Further, in order to realize accurate location, caster 3 being provided with guide pillar 18, male template 9 being formed with the guide frame 19 coordinated with guide pillar 18.
Preferred as one, push rod 15 is a pair, parallel arranged and through same push rod bundle block 20, off normal does not occur when guaranteeing to eject.Preferably, thimble 14 is two, is divided into the both sides of push rod 15.
More than show and describe general principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
