Abstract
The utility model discloses a spring mould of a polyvinyl chloride packaging box fastener. The spring mould comprises an outer mould, an inner mould and a fixing bracket, wherein the inner mould comprises a left arc surface, a right arc surface and a middle ring surface, the left arc surface is movably connected to the left side of the middle ring surface through the convex edge of the left arc surface, the right arc surface is movably connected to the right side of the middle ring surface through the convex edge of the right arc surface, the convex edge of the left arc surface and the convex edge of the right arc surface are mutually sleeved, the width of the convex edge of the left arc surface and the right arc surface is less than that of the middle ring surface, and a spring is arranged between the left arc surface and the right arc surface. Compared with the prior art, the spring mould has the beneficial effects that during demoulding, the left arc surface and the right arc surface of the inner mould can be gathered together in the middle ring surface under the action of an extruding force, the formed fastener can be easily demoulded; and the left arc surface and the right arc surface restore under the elastic force of the spring when the extruding force disappears, continuous production is performed, and thus the spring mould is convenient and practical.
Description
Technical field
The utility model relates to a kind of floating die assembly of plastic packing box fastener.
Background technology
At the opening part of plastic packing box, be typically provided with up and down the moving fastening of being easy to open of coordinating and fastening, this fastener comprises a protruding fixture block and a narrower eck.In existing production process; use internal mold and an external mold of a fixed profile; after external mold matched moulds, compressed air is blown into plastic sheet, internal mold is enveloped, after formed product; external mold is opened; machine clips the fastener demoulding of moulding, but because the eck of fastener is narrower, is not easy the demoulding; or when the demoulding, damage fastener, conventionally go back push rod structure assisted demoulding.
Utility model content
The problems referred to above that the utility model need to solve are for above-mentioned the deficiencies in the prior art, and a kind of floating die assembly of plastic packing box fastener is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of floating die assembly of plastic packing box fastener, comprise external mold, internal mold and fixed support, described internal mold comprises left arc surface, right arc surface and middle anchor ring, the left side of anchor ring in the middle of left arc surface is movably connected in by left arc surface chimb, the right side of anchor ring in the middle of right arc surface is movably connected in by right arc surface chimb, left arc surface chimb and right arc surface chimb are socketed mutually, and in the middle of the width of left arc surface chimb and right arc surface chimb is less than, the width of anchor ring, is provided with spring between left arc surface and right arc surface.
Described left arc surface chimb is socketed in right arc surface chimb, is arranged with the first chute of two levels on right arc surface chimb, and the first chute two ends are provided with rib, in the corresponding position, inner side of middle anchor ring, is respectively equipped with first projection suitable with the first chute.
The second chute that is arranged with two levels on described left arc surface chimb, the second chute two ends are provided with rib, and inside right arc surface chimb, corresponding position is respectively equipped with second projection suitable with the second chute.
Compared with prior art, the beneficial effects of the utility model are: during the demoulding, the left arc surface of inner membrance and right arc surface are under the effect of extruding force, can in middle anchor ring, gather, the just demoulding easily of the fastener of forming, when extruding force disappearance rear left arc surface and right arc surface, under the elastic force at spring, restore to the original state again, continue to produce, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the floating die assembly of plastic packing box fastener of the present utility model;
Wherein, 1, external mold, 2, internal mold, 3, left arc surface, 4, right arc surface, 5, middle anchor ring, 6, left arc surface chimb, 7, right arc surface chimb, 8, spring, 9, fixed support, 10, the first chute, the 11, first projection, the 12, second chute, the 13, second projection.
The specific embodiment
Below in conjunction with accompanying drawing, describe optimal technical scheme of the present utility model in detail.
As shown in Figure 1, a kind of floating die assembly of plastic packing box fastener, comprise external mold 1, internal mold 2 and fixed support 9, internal mold 2 comprises left arc surface 3, right arc surface 4 and middle anchor ring 5, the left side of anchor ring 5 in the middle of left arc surface 3 is movably connected in by left arc surface chimb 6, the right side of anchor ring 5 in the middle of right arc surface 4 is movably connected in by right arc surface chimb 7, left arc surface chimb 6 and right arc surface chimb 7 are socketed mutually, and in the middle of the width of left arc surface chimb 6 and right arc surface chimb 7 is less than, the width of anchor ring 5, is provided with spring 8 between left arc surface 3 and right arc surface 4.
Left arc surface chimb 6 is socketed in right arc surface chimb 7, on right arc surface chimb 7, be arranged with the first chute 10 of two levels, the first chute 10 two ends are provided with rib, in the corresponding position, inner side of middle anchor ring 5, be respectively equipped with first projection 11 suitable with the first chute 10, the right arc surface chimb 7 of the first 11 pairs of projections carries out spacing, makes right arc surface chimb 7 can not depart from middle anchor ring 5.
On left arc surface chimb 6, be arranged with the second chute 12 of two levels, the second chute 12 two ends are provided with rib, in right arc surface chimb 7 corresponding positions, inner side, be respectively equipped with second projection 13 suitable with the second chute 12, the left arc surface chimb 6 of the second 13 pairs of projections carries out spacing, makes left arc surface chimb 6 can not depart from right arc surface chimb 7.
The floating die assembly of plastic packing box fastener of the present utility model, during the demoulding, the left arc surface 3 of inner membrance 2 and right arc surface 4 are under the effect of extruding force, can in middle anchor ring 5, gather, the just demoulding easily of the fastener of forming, the reinstatement again under the elastic force of spring 8 when extruding force disappearance rear left arc surface 3 and right arc surface 4, continues to produce, convenient and practical.
