Abstract

The invention discloses a kind of plastic mould of automatic demoulding, including:Moving platen and solid plate; punch insert is provided with the moving platen; die plate insert corresponding with punch insert is provided with the solid plate; the punch insert external concentric is provided with a stripper rings; the depression bar for pointing to moving platen is provided with the solid plate, indent is provided with spring eye corresponding with depression bar on the moving platen, and spring is provided with the spring eye; the spring end is provided with the floating post for pointing to depression bar, is provided with connecting plate between the stripper rings surrounding and floating post and is fixed.By the above-mentioned means, the plastic mould of automatic demoulding of the present invention, during die sinking, floating post ejects under the action of the spring, and stripper rings promote product edge and come off from punch insert, realize automatic demoulding, job stability is high, and operation and maintenance is more convenient.

Description

A kind of plastic mould of automatic demoulding
Technical field
The present invention relates to mould applications, more particularly to a kind of plastic mould of automatic demoulding.
Background technology
Injection mold is relatively common plasthetics production mould, is generally made up of dynamic model and cover half, carries out folding And injection molding.
Because the temperature of injecting products is high, plastic cement products easily remain on mould and can not automatic demoulding, it is necessary in addition Stripper apparatus is installed, the driving of stripper apparatus is carried out using hydraulic stem, is stripped after die sinking, but the control of hydraulic stem needs To be matched with open time, complex designing, stability in use is poor, and maintenance cost is high.
The content of the invention
The present invention solves the technical problem of a kind of plastic mould of automatic demoulding is provided, realize automatic after die sinking The demoulding, cost is reduced, lift job stability.
In order to solve the above technical problems, one aspect of the present invention is:A kind of plastic cement of automatic demoulding is provided Mould, including:Moving platen and solid plate, punch insert is provided with the moving platen, be provided with the solid plate and punch insert Corresponding die plate insert, the punch insert external concentric are provided with a stripper rings, sensing moving platen are provided with the solid plate Depression bar, indent is provided with spring eye corresponding with depression bar on the moving platen, and spring, the bullet are provided with the spring eye Spring end set has the floating post for pointing to depression bar, is provided with connecting plate between the stripper rings surrounding and floating post and is fixed.
In a preferred embodiment of the present invention, the guiding slide bar of connecting plate is provided through on the moving platen.
In a preferred embodiment of the present invention, the lead for pointing to solid plate is provided with the moving platen, it is described fixed Guide sleeve corresponding with lead is provided with template.
In a preferred embodiment of the present invention, the floating post end set has cushion pad.
In a preferred embodiment of the present invention, the cushion pad is nylon6 chips or sheet rubber.
In a preferred embodiment of the present invention, the depression bar annular array is distributed in the surrounding of die plate insert.
The beneficial effects of the invention are as follows:A kind of plastic mould for automatic demoulding that the present invention points out, during matched moulds, depression bar promotes Floating post is retreated so that stripper rings are contacted and fixed with moving platen, are then molded, and are molded after cooling, work of the floating post in spring With lower ejection, stripper rings promote product edge and come off from punch insert, realize automatic demoulding, job stability is high, uses Be easily serviced.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, make required in being described below to embodiment Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for For those of ordinary skill in the art, on the premise of not paying creative work, it can also be obtained according to these accompanying drawings other Accompanying drawing, wherein:
Fig. 1 is a kind of structural representation of the preferred embodiment of plastic mould one of automatic demoulding of the present invention.
Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation Example is only the part of the embodiment of the present invention, rather than whole embodiments.It is common based on the embodiment in the present invention, this area All other embodiment that technical staff is obtained under the premise of creative work is not made, belong to the model that the present invention protects Enclose.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of plastic mould of automatic demoulding, including:Moving platen 1 and solid plate 2, punch insert 6 is provided with the moving platen 1, It is provided with die plate insert 5 corresponding with punch insert 6 on the solid plate 2, during matched moulds, punch insert 6 combines to form product with die plate insert 5 Die cavity.
The external concentric of punch insert 6 is provided with a stripper rings 7, is provided with the solid plate 2 and points to moving platen 1 Depression bar 9, indent is provided with spring eye 10 corresponding with depression bar 9 on the moving platen 1, and spring is provided with the spring eye 10 11, the end set of spring 11 has the floating post 8 for pointing to depression bar 9, is provided between the surrounding of stripper rings 7 and floating post 8 Connecting plate 13 is fixed.During matched moulds, depression bar 9 promotes floating post 8 to retreat so that and stripper rings 7 are contacted and fixed with moving platen 1, Then be molded, molded after cooling, floating post 8 ejects in the presence of spring 11, stripper rings 7 promote product edge and from punch insert Come off on 6, realize automatic demoulding.
The guiding slide bar 14 of connecting plate 13 is provided through on the moving platen 1, improves connecting plate 13 and stripper rings 7 The moving stability, avoid the situation of deflection.
The lead 3 for pointing to solid plate 2 is provided with the moving platen 1, is provided with and lead 3 on the solid plate 2 Corresponding guide sleeve 4, improve the stability height of the fit precision of moving platen 1 and solid plate 2, die sinking and matched moulds.
The end set of floating post 8 has cushion pad 12, and the cushion pad 12 is nylon6 chips or sheet rubber, reduces and floats Noise and impact when post 8 hits with depression bar 9, lift durability.
The annular array of depression bar 9 is distributed in the surrounding of die plate insert 5 so that than more uniform, reduction moves the stress of stripper rings 7 Skew problems during dynamic.
In summary, the plastic mould for a kind of automatic demoulding that the present invention points out, the work(of automatic demoulding when realizing die sinking Can, job stability is high, and operation and maintenance is more convenient, reduces production cost.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair The equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks Domain, it is included within the scope of the present invention.
