Abstract
The invention discloses a spring plate mould of a plastic-adsorption packing box fastener. The spring plate mould comprises an outer mould, an inner mould and a fixed bracket, wherein the inner mould comprises a left arc surface, a right arc surface and a middle annular surface; the left arc surface and the right arc surface are respectively and movably connected with two sides of the middle annular surface through flanges, and the flanges are internally tangent to the inner side surface of the middle annular surface; a V-shaped spring plate is fixed on the inner side surface of the middle annular surface; two free ends of the V-shaped spring plate are respectively hinged to the centers of the inner sides of the left arc surface and the right arc surface. Compared with the prior art, the spring plate mould of the plastic-adsorption packing box fastener has the benefits that the inner mould comprises the left arc surface, the right arc surface of the middle annular surface, during demoulding, the left arc surface and the right arc surface can be gathered towards the interior of the middle annular surface under the action of the extrusion force, and the formed fastener can realize demoulding easily, and when the extrusion force disappears, the left arc surface and the right arc surface are recovered under the elastic force of the V-shaped spring plate, the production is performed continuously, and convenience and practicability are realized.
Description
Technical field
The present invention 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 the 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; perhaps infringement fastener when the demoulding, go back the push rod structure assisted demoulding usually.
Summary of the invention
The problems referred to above that the present invention 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 used in the present invention 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, be fixed with the V-type shell fragment on the medial surface of middle anchor ring, two free ends of V-type shell fragment are hinged on respectively the central authorities of left arc surface and right arc surface inboard.
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 invention has the beneficial effects as follows: 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.
The accompanying drawing explanation
Fig. 1 is the structural representation of the shell fragment mould of plastic packing box fastener of the present invention;
Wherein, 1, external mold, 2, internal mold, 3, left arc surface, 4, right arc surface, 5, middle anchor ring, 6, flange, 7, the V-type shell fragment, 8, fixed support.
The specific embodiment
Describe the preferred technical solution of the present invention in detail below in conjunction with accompanying drawing.
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 inboards.
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 fully in the middle of anchor ring 5 inside.
The shell fragment mould of plastic packing box fastener of the present invention, 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)
