Description
Technical field
The utility model relates to technical field of mold, particularly relates to a kind of cavity core pulling structure.
Background technology
Along with improving constantly of scientific and technological level, people are also more strict to the requirement of product appearance quality.In the process of plastic mould design; some product side is fluted or perforation is not consistent with ejecting direction and die sinking direction; therefore mould needs to do slide block or the normal demoulding of slant-top core-pulling ability; because product appearance requires that high surfaces can not have the clamp of slide block, under causing a lot of situation, cover half slide block can only be done.Common way is that cover half leaves a mould to realize slipper block loose core more, and whole process mould structure is complicated, and cost is high, the production cycle long (especially large mould).
Utility model content
The purpose of this utility model is to provide a kind of cavity core pulling structure for the deficiencies in the prior art, and this structure has structure and simply, greatly reduces Mold Making cost, adds die life.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of cavity core pulling structure, include oil cylinder, the axle head of described oil cylinder is equiped with the slide block be installed in cover half template, slide block is by being connected with the axle head of described oil cylinder in criss-cross oil cylinder connector, described oil cylinder connector side is provided with locating piece, described locating piece and slider side end are equiped with the slider layering of band groove, and described slide block, oil cylinder connector, locating piece and slider layering are installed in described cover half template upper end.
Wherein, described oil cylinder is installed in described cover half template by cylinder bracket.
Wherein, described locating piece is provided with two and with the axis of described oil cylinder connector for symmetry axis.
Wherein, the corner of described locating piece is provided with chamfering.
Wherein, described slide block is provided with two and with the axis of described slide block for symmetry axis.
The beneficial effects of the utility model are: a kind of cavity core pulling structure described in the utility model, include oil cylinder, the axle head of described oil cylinder is equiped with the slide block be installed in cover half template, slide block is by being connected with the axle head of described oil cylinder in criss-cross oil cylinder connector, described oil cylinder connector side is provided with locating piece, described locating piece and slider side end are equiped with the slider layering of band groove, described slide block, oil cylinder connector, locating piece and slider layering are installed in described cover half template upper end, it is simple that the utility model has structure, greatly reduce Mold Making cost, add the advantage of die life.
Accompanying drawing explanation
Utilize accompanying drawing to be further detailed the utility model below, but the embodiment in accompanying drawing is not formed any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is close-up schematic view of the present utility model.
Include in Fig. 1-2:
1---oil cylinder 11---cylinder bracket
2---cover half template 3---slide block
4---oil cylinder connector 5---locating piece
51---chamfering 6---slider layering
61---groove.
Detailed description of the invention
Below in conjunction with concrete embodiment, the utility model is described.
As shown in Figure 1, a kind of cavity core pulling structure, include oil cylinder 1, the axle head of described oil cylinder 1 is equiped with the slide block 3 be installed in cover half template 2, slide block 3 is by being connected with the axle head of described oil cylinder 1 in criss-cross oil cylinder connector 4, described oil cylinder connector 4 side is provided with locating piece 5, and described locating piece 5 and slide block 3 side are equiped with slider layering 6, and described slide block 3, oil cylinder connector 4, locating piece 5 and slider layering 6 are installed in described cover half template 2 upper end.
Further, described oil cylinder 1 is installed in described cover half template 2 by cylinder bracket 11.
Further, described locating piece 5 is provided with two and with the axis of described oil cylinder connector 4 for symmetry axis.
Further, as shown in Figure 2, the corner of described locating piece 5 is provided with chamfering 51.
Further, described slide block 6 is provided with two and with the axis of described slide block 3 for symmetry axis.
Need further explain, the utility model operationally, described oil cylinder 1 outward movment is loosed core with oil cylinder 1 toward interior motion reset two states, when described oil cylinder 1 outward movment is loosed core, first oil cylinder connector 4 is driven to shrink back by oil cylinder 1, make oil cylinder connector 4 no longer withstand locating piece 5, continue locating piece 5 past slide block 3 middle slip under the effect of chamfering 51 under the driving of oil cylinder 1.The realization that continues to shrink back together under the driving of described oil cylinder 1 of described slide block 3, oil cylinder connector 4 and locating piece 5 is loosed core; Reset toward interior motion, described slide block 3, oil cylinder connector 4 and locating piece 5 back move under the driving of described oil cylinder 1, finally making locating piece 5 just block is positioned at inside described slider layering 6 at the whole like this slide block 3 of groove 61 inner position of described slider layering 6, ensure that the injection pressure sliding block 3 when injection moulding does not shrink back., therefore the utility model to have structure simple, mold actions is simplified, greatly reduces Mold Making cost, add the advantage of die life.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
