Abstract
The invention discloses a spring mould of a plastic-adsorption packing box fastener. The spring 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 is movably connected with the left side of the middle annular surface through a left arc surface convex edge, and the right arc surface is movably connected with the right side of the middle annular surface through a right arc surface convex edge; the left arc surface convex edge and the right arc surface convex edge are mutually connected in a sleeving way, and the width of each of the left arc surface convex edge and the right arc surface convex edge is less than that of the middle annular surface; a spring is arranged between the left arc surface and the right arc surface. Compared with the prior art, the spring mould of the plastic-adsorption packing box fastener has the benefits that during demoulding, the left arc surface and the right arc surface of the inner mould can be gathered towards the interior of the middle annular surface under the action of 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 spring, the production is performed continuously, and convenience and practicability are realized.
Description
Technical field
The present invention 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 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 floating die assembly 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 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, be 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 inboard corresponding position of middle anchor ring, is respectively equipped with first projection suitable with the first chute.
Be arranged with the second chute of two levels on described left arc surface chimb, the second chute two ends are provided with rib, in the inboard corresponding position of right arc surface chimb, are respectively equipped with second projection suitable with the second chute.
Compared with prior art, the invention has the beneficial effects as follows: 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, restore to the original state again under the elastic force at spring when extruding force disappearance rear left arc surface and right arc surface, continue to produce, convenient and practical.
The accompanying drawing explanation
Fig. 1 is the structural representation of the floating die assembly 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, 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
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 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 the width of anchor ring 5 in the middle of the width of left arc surface chimb 6 and right arc surface chimb 7 is less than, be 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, be arranged with the first chute 10 of two levels on right arc surface chimb 7, the first chute 10 two ends are provided with rib, be respectively equipped with first projection 11 suitable with the first chute 10 in the inboard corresponding position of middle anchor ring 5, the right arc surface chimb 7 of the first 11 pairs of projections carries out spacing, makes right arc surface chimb 7 can not break away from middle anchor ring 5.
Be arranged with the second chute 12 of two levels on left arc surface chimb 6, the second chute 12 two ends are provided with rib, be respectively equipped with second projection 13 suitable with the second chute 12 in the inboard corresponding position of right arc surface chimb 7, the left arc surface chimb 6 of the second 13 pairs of projections carries out spacing, makes left arc surface chimb 6 can not break away from right arc surface chimb 7.
The floating die assembly of plastic packing box fastener of the present invention, 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, continue to produce, convenient and practical.
