Abstract
The utility model provides a mold emptier used for a product with full circle of under cuts. The mold emptier used for the product with the full circle of under cuts enables the product to be prevented from being damaged during demolding, ensures normal running of production, and enables production efficiency to be high. The mold emptier used for the product with the full circle of under cuts comprises a front mold core and a back mold core. The mold emptier used for the product with the full circle of under cuts is characterized in that the outer ring surface of a mold cavity is formed by the front mold core and the back mold core. The mold emptier used for the product with the full circle of under cuts further comprises two sliding blocks arranged symmetrically relative to the axis of the mold cavity, and two oblique bars arranged symmetrically relative to the axis of the mold cavity, wherein the sliding blocks and the oblique bars are arranged at intervals, the inner ring surface of the mold cavity is formed by outer ring surfaces of the upper portions of the sliding blocks and the oblique bars, the sliding blocks are capable of sliding along the horizontal radial plane of the mold cavity, a gap is reserved between end faces of inner sides of the two sliding blocks, space is reserved between end faces of inner sides of upper portions of the two oblique bars, outer lateral walls of the oblique bars are tightly attached to the inner wall of a guiding hole of the back mold core, and the inner wall of the guiding hole contracts inwards from bottom to top in a tilted mode.
Description
Technical field
The utility model relates to the technical field of injection mould mould structure, is specially the mould emptier that whole circle back-off is arranged on a kind of product.
Background technology
Product tends to run into such problem when making mould, there is the back-off of whole circle the product inboard, and back-off is darker, and existing Enforced stripping structure can't be suitable for, and causes the production efficiency of product low.
Summary of the invention
For the problems referred to above, the utility model provides the mould emptier that whole circle back-off is arranged on a kind of product, it makes product can not damage product when the demoulding, guaranteed to produce normally carry out, production efficiency is high.
the mould emptier of whole circle back-off is arranged on a kind of product, its technical scheme is such: it comprises front cavity, rear cavity, it is characterized in that: described front cavity, rear cavity has surrounded the outer ring surface of die cavity, it also comprises two slide blocks that are arranged symmetrically with about the die cavity axle center, two braces that are arranged symmetrically with about the die cavity axle center, described slide block, the brace interval is arranged, described slide block, the top outer ring surface of brace forms the inner ring surface of described die cavity, described slide block can slide along the horizontal radial horizontal plane of die cavity, leave the gap between the inner side end of two described slide blocks, leave spacing between the inner side end on the top of two described braces, the lateral wall of described brace is close to from bottom to top the inwardly inwall of the pilot hole of the rear cavity of gradient contraction.
After adopting said structure of the present utility model, during the demoulding, front cavity upwards detaches, two slide blocks are respectively to the axe movement of die cavity, back-off on slide block breaks away from product, latter two brace upwards eject respectively, because brace is subject to the restriction of pilot hole on gradient, when product is upwards ejected, also inwardly to the axe movement of die cavity, like this, the back-off on product is with regard to break away from moulds, it makes product can not damage product when the demoulding, guaranteed to produce normally carry out, production efficiency is high.
Description of drawings
Fig. 1 is top view structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 cuts open structural representation;
Fig. 3 is that the B-B of Fig. 1 cuts open structural representation.
The specific embodiment
see Fig. 1, Fig. 2, Fig. 3, it comprises front cavity 1, rear cavity 2, front cavity 1, rear cavity 2 has surrounded the outer ring surface of die cavity, it also comprises two slide blocks 4 that are arranged symmetrically with about die cavity axle center 3, two braces 5 that are arranged symmetrically with about die cavity axle center 3, slide block 4, brace 5 intervals are arranged, slide block 4, the top outer ring surface of brace 5 forms the inner ring surface of die cavity, be product 6 in die cavity, slide block 4 can slide along the horizontal radial horizontal plane of die cavity, leave clearance D between the inner side end of two slide blocks 4, leave spacing H between the inner side end on the top of two braces 5, the lateral wall of brace 5 is close to from bottom to top the inwardly inwall of the pilot hole 7 of the rear cavity 2 of gradient contraction.
