Description
Technical field
The utility model relates to a kind of injection mold auxiliary reset mechanism, particularly a kind of jacking block antecedence reposition mechanism of injection mold.
Background technology
Plastic cement products is produced by injection mold mostly, and the performance direct relation of injection mold production efficiency, the quality of plastic cement products.At present, in injection mold, the jacking block fundamental sum mold integral of being located on ejector retainner plate resets simultaneously, and the wedge angle face of jacking block is easy to bump with die cavity and cause damage, thereby affects die life.
Summary of the invention
The purpose of this utility model is to provide a kind of jacking block antecedence reposition mechanism of injection mold, the problem of easily colliding die cavity to solve the wedge angle face of the jacking block that prior art exists.
In order to address the above problem, the utility model provides following technical scheme:
A kind of jacking block antecedence reposition mechanism of injection mold, for being arranged on the side of injection mold, the jacking block of injection mold is resetted at first, described injection mold comprises die cavity and the moving platen of mutual correspondence, lower compound plate, be located at the mould pin between described lower compound plate and described moving platen, the ejector retainner plate and the thimble compound plate that between described moving platen and described lower compound plate, move, be located at the jacking block on described ejector retainner plate, wherein, the jacking block antecedence reposition mechanism of described injection mold comprises: release link, the side of described die cavity is fixed in one end, the other end points to described ejector retainner plate direction and end is fillet, limited block, inboard side is flat face, is fixed on the side of described mould pin, back-up block, inboard side is flat face, be fixed on the side of described ejector retainner plate and thimble compound plate, the inboard side of described limited block and the inboard lateral vertical of described back-up block also intersect, and the other end end of described release link is corresponding with the intersection of the inboard side of described back-up block and the inboard side of described limited block, when described ejector retainner plate and thimble compound plate move up and down, described back-up block moves along the inboard side of described limited block, fork, one end is articulated with the side of described moving platen, and the other end slides on the inboard side of described limited block, back-up block.
Preferably, the inboard side of described limited block is a chamfering near the position of described moving platen.
Analyze knownly, the utility model is applied to mould, when matched moulds, resetting block, under clamping pressure effect, can drive fork to rotate by limited block, forces back-up block to return by force initial point, make jacking block antecedence reposition, thereby guarantee that jacking block wedge angle face contacts with after die cavity, increases die life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the matched moulds state of the applied injection mold of the utility model embodiment;
Fig. 2 is the structural representation of the mold closing state of the applied injection mold of the utility model embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1 and Figure 2, the utility model embodiment comprises release link 81, fork 82, limited block 83, back-up block 84.During application, the present embodiment is arranged on the side of a plurality of parts of injection mold, the jacking block 4 of injection mold is resetted at first, again as shown in Figure 1 and Figure 2, this injection mold comprises the die cavity 1 of mutual correspondence and moving platen 2, lower compound plate 7, be located at mould pin 3 between lower compound plate 7 and moving platen 2, between moving platen 2 and lower compound plate 7 mobile ejector retainner plate 5 and thimble compound plate 6, be located at jacking block 4 on ejector retainner plate 5 etc.
Particularly, the side of die cavity 1 is fixed in one end of release link 81 by screw 91, and the other end points to ejector retainner plate 5 directions, and this other end end 811 be fillet, is also the comparatively sharp-pointed corner angle of end 811 nothing.The inboard side 832 of limited block 83 is flat face, is fixed on the side of mould pin 3 by screw 92.The inboard side 841 of back-up block 84 is flat face, and this back-up block 84 is fixed on the side of ejector retainner plate 5 and thimble compound plate 6 simultaneously by screw 93.The inboard side 832 of limited block 83 is vertical with the inboard side 841 of back-up block 84 and crossing, and the intersection of the other end end of release link 81 and the inboard side 841 of back-up block 84 and the inboard side 832 of limited block 83 is corresponding.When ejector retainner plate 5 and thimble compound plate 6 move up and down, back-up block 84 moves along the inboard side 832 of limited block 83.One end of fork 82 is articulated with the side of moving platen 2 by bearing pin 822, other end end 821 in the inboard side 832 of limited block 83, slide on the inboard side 841 of back-up block 84.
In order to be slided smoothly along the inboard side 832 of limited block 83 in the end 811 of release link 81, the inboard side 832 of limited block 83 is a chamfering 831 near the position of moving platen 2.
When the injection mould closing of application the present embodiment, the end 811 of release link 81, under clamping pressure effect, squeezes fork 82 by limited block 83 and rotates around bearing pin 822, forces back-up block 84 to return by force initial point, makes jacking block antecedence reposition.Guarantee that jacking block wedge angle face contacts with the rear of die cavity 1, increases die life.
In sum, the utility model can time injection mold jacking block when matched moulds, prior to the mechanism such as die cavity, reset, avoid jacking block first to contact with die cavity, thus prolongation die life.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not depart from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, and is not only.All changes within the scope of the utility model or within being equal to scope of the present utility model are all included in the utility model.
