Abstract
The invention provides a demolding mechanism with a product provided with a whole circle of inverted buckles. During demolding, the product is not damaged, normal production is guaranteed, and the production efficiency is high. The mechanism comprises a front mold core and a rear mold core and is characterized in that an outer circular surface of a cavity is defined by the front mold core and the rear mold core. The mechanism also comprises two sliding blocks which are symmetrical to an axis of the cavity and two inclined rods which are symmetrical to the axis of the cavity, the sliding blocks and the sliding rods are arranged at intervals, upper portion outer circular surfaces of the sliding blocks and the inclined rods form an inner circular surface of the cavity, the sliding blocks can slide in a horizontal plane along a radial direction of the cavity, gaps exist between inner side end faces of the two sliding blocks, distances are reserved between inner side end faces of the upper portions of the inclined rods, the inclined rods on the lower portion of an inclined top are supported in a guide hole of the rear mold core which is retracted inwards in an inclined mode from bottom to top.
Description
Technical field
The present invention relates to the technical field of injection mould mould structure, be specially the mould emptier that whole circle back-off is arranged on the 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 invention provides the mould emptier that whole circle back-off is arranged on the product, it not be so that product can damage product when the demoulding, guaranteed to produce normally carry out, production efficiency is high.
The mould emptier that whole circle back-off is arranged on the 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 bottom brace of described oblique top is supported on from bottom to top in the pilot hole of the rear cavity that inside gradient shrinks.
After adopting said structure of the present invention, during the demoulding, front cavity upwards detaches, two slide blocks are respectively to the axe movement of die cavity, back-off on the slide block breaks away from product, oblique two oblique tops upwards eject respectively afterwards, because oblique top 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 the product is with regard to break away from moulds, it not be so that product can 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 invention;
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 the 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 bottom brace of oblique top 5 is supported on from bottom to top in the pilot hole 7 of the rear cavity 2 that inside gradient shrinks.
