Abstract
The utility model discloses an elastic sheet mould of a polyvinyl chloride packaging box fastener. The elastic sheet 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 and the right arc surface are respectively movably connected to two sides of the middle ring surface through flanges, the flanges are internally tangent to the inner side surface of the middle ring surface, a V-shaped elastic sheet is fixed on the inner side surface of the middle ring surface, two free ends of the V-shaped elastic sheet are respectively hinged in the centers of the inner sides of the left arc surface and the right arc surface. Compared with the prior art, the elastic sheet mould has the beneficial effects that the inner mould comprises the left arc surface, the right arc surface and the middle ring surface, during demoulding, the left arc surface and the right arc surface 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 V-shaped elastic sheet when the extruding force disappears, continuous production is performed, and thus the elastic sheet mould is convenient and practical.
Description
Technical field
The utility model relates to a kind of shell fragment mould 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 shell fragment mould 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 shell fragment mould 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 both sides of anchor ring in the middle of left arc surface and right arc surface are movably connected in by flange respectively, the medial surface of anchor ring in the middle of flange is inscribed within, on the medial surface of middle anchor ring, be fixed with V-type shell fragment, two free ends of V-type shell fragment are hinged on respectively the central authorities of left arc surface and right arc surface inner side.
Half of width of anchor ring in the middle of the width of described flange is less than or equal to.
Compared with prior art, the beneficial effects of the utility model are: internal mold comprises left arc surface, right arc surface and middle anchor ring, during the demoulding, left arc surface 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 pulling force disappearance rear left arc surface and right arc surface restore to the original state again under the elastic force of V-type shell fragment, continue to produce, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the shell fragment mould 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, flange, 7, V-type shell fragment, 8, fixed support.
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 shell fragment mould of plastic packing box fastener, comprise external mold 1, internal mold 2 and fixed support 8, described internal mold 2 comprises left arc surface 3, right arc surface 4 and middle anchor ring 5, the both sides of anchor ring 5 in the middle of left arc surface 3 and right arc surface 4 are movably connected in by flange 6 respectively, in the middle of flange 6 is inscribed within, the medial surface of anchor ring 5 is fixed with V-type shell fragment 7 on the medial surface of middle anchor ring 5, and two free ends of V-type shell fragment 7 are hinged on respectively the central authorities of left arc surface 3 and right arc surface 4 inner sides.
Half of width of anchor ring 5 in the middle of the width of flange 6 is less than or equal to, guarantee left arc surface 3 and right arc surface 4 can shrink completely in the middle of anchor ring 5 inside.
The shell fragment mould of plastic packing box fastener of the present utility model, internal mold 2 comprises left arc surface 3, right arc surface 4 and middle anchor ring 5, during the demoulding, left arc surface 3 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, when pulling force disappearance rear left arc surface 3 and right arc surface 4 restore to the original state again under the elastic force of V-type shell fragment 7, continue to produce, convenient and practical.
Claims (2)
