Abstract
The invention discloses a movable mould of a plastic-adsorption packing box fastener. The movable mould comprises an outer mould and an inner mould, wherein the upper end of the inner mould is spherical and 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; one or more springs are arranged between the left arc surface and the right arc surface; movable bars are respectively hinged to the centers of inner sides of the left arc surface and the right arc surface; the two movable bars are mutually connected, and a pull rod is hinged to the connecting part of the movable bars; the lower end of the pull rod is internally tangent to a hole of a column at the lower end of the inner mould. Compared with the prior art, the movable mould of the plastic-adsorption packing box fastener has the benefits that the upper end of the inner mould is spherical and comprises the left arc surface, the right arc surface and the middle annular surface, and the left arc surface and the right arc surface can be pulled by the pull rod to be gathered towards the interior of the middle annular surface, so that the formed fastener can realize demoulding easily, and when the pulling force disappears, the left arc surface and the right arc surface are recovered under the elastic force of the springs, the production is performed continuously, and convenience and practicability are realized.
Description
Technical field
The present invention relates to a kind of flexible 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 flexible 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 flexible mould of plastic packing box fastener, comprise external mold and internal mold, the upper end of described internal mold is spheroidal, comprise 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 provided with at least one spring between left arc surface and right arc surface, center in left arc surface and right arc surface inboard is hinged with respectively motion bar, between two motion bars, interconnect, and be hinged with pull bar in junction, the lower end of described pull bar is inscribed within the cylindrical hole of internal mold lower end.
In the middle of described, the width of anchor ring equals the width of cylinder.
The length of described motion bar equals the radius of the upper end ball of internal mold.
Compared with prior art, the invention has the beneficial effects as follows: the internal mold upper end is spherical shape, comprise left arc surface, right arc surface and middle anchor ring, left arc surface and right arc surface are under the pulling of pull bar, 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 pulling 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 flexible 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, spring, 7, motion bar, 8, pull bar, 9, cylinder, 10, flange.
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 flexible mould of plastic packing box fastener, comprise external mold 1 and internal mold 2, the upper end of internal mold 2 is spheroidal, comprise 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 10 respectively, the medial surface of anchor ring 5 in the middle of flange 10 is inscribed within, be provided with at least one spring 6 between left arc surface 3 and right arc surface 4, center in left arc surface 3 and right arc surface 4 inboards is hinged with respectively motion bar 7, between two motion bars 7, interconnect, and be hinged with pull bar 8 in junction, the lower end of described pull bar 8 is inscribed within cylinder 9 holes of internal mold 2 lower ends.
In the middle of the width of anchor ring 5 equal the width of cylinder 9, make the eck of the fastener after moulding and the in the same size of middle anchor ring 5, conveniently stripped.
The length of motion bar 7 equals the radius of the upper end ball of internal mold 2, between two motion bars 7 and spring 6, cooperatively interacts, and keeping the upper end of internal mold 2 is spheroidal.
The flexible mould of plastic packing box fastener of the present invention, internal mold 2 upper ends are spherical shape, comprise left arc surface 3, right arc surface 4 and middle anchor ring 5, left arc surface 3 and right arc surface 4 are under the pulling of pull bar 8, can be to 5 gathering in middle anchor ring, 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 spring 6, continue to produce, convenient and practical.
