Description
Technical field
The utility model relates to the slide fastener technical field of processing equipment, relates in particular to a kind of at the upper and lower equipment that ends button of nylon zipper injection moulding.
Background technology
Known upper and lower only deduction of points is not the buckle with the bonding jumper bending forming, because two end is not sealed, thereby the easy clothing that scratches near it in these two ends, if this slide fastener is installed on pillow, two ends of the buckle that does not seal are also clamped people's hair easily.Moreover, end button or when only detaining down,, buckle is opened, cause slider slippage from the tooth chain because two ends of buckle are not sealed when slider clashes into repeatedly.Many producers injection machine is also arranged now, adopt Shooting Technique that the direct pressure injection of plastics fusion is detained to the upper end or the ending of bottom formation closed type of zipper strip, this button that ends not only is connected firmly, and is not easy to scratch the clothing near it, uses more safe and reliable.But, only to buckle with this device fabrication slide fastener, its yield rate is lower, and the quality instability has limited the promotion and application of this slide fastener.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of slide fastener only to buckle injection machine, only to buckle in the injection moulding process yield rate low to solve slide fastener, the quality problem of unstable.
For solving the problems of the technologies described above, the technical solution of the utility model is: slide fastener is only buckled injection machine, comprise two guide upright posts that are installed on frame, be fixed in the upper die body of top mold frame and be fixed in the lower mold body of mould bases down, described top mold frame is fixedlyed connected with guide upright post, and described down mould bases is installed on guide upright post and is connected with and can make down mould bases along the guide upright post power set that realization die sinking, matched moulds move that endwisely slip; Described upper die body is provided with plastics fusion coupler, can form the only upper and lower buckling die chamber of ending in buckling die chamber when upper and lower die body is respectively equipped with matched moulds; The die face of described lower mold body has a groove that can hold fastener stringer, described groove extends to and describedly ends down the buckling die chamber and be provided with a projection that can lean the fastener stringer end at groove with the intersection of ending the buckling die chamber down, and described lower mold body is provided with the elasticity clamping and pressing device that slide fastener can be pressed in the lower mold body die face.
Because the die face of lower mold body has one to ending the groove that extend in the buckling die chamber, before injection moulding begins, can be earlier the tooth chain of slide fastener be placed in the groove, the end of tooth chain leans the projection that is arranged at groove and ends the junction in buckling die chamber, thereby slide fastener is located on lower mold body reliably, and slide fastener is pressed on the mold cavity surface of lower mold body by the elasticity clamping and pressing device.Like this, when matched moulds, slide fastener can not move, and has guaranteed only to be buckled in the position consistency of injection moulding on the slide fastener, has improved the yield rate that slide fastener is only buckled.
As a kind of improvement, described lower mold body comprises cope match-plate pattern and the lower bolster that is fixed together, when having matched moulds in the corresponding position, plastics fusion coupler position with upper die body, described cope match-plate pattern can form the hole that the chamber is injected in the plastics fusion with plastics fusion coupler, a pin is installed in the described hole, an otch has been cut in the upper end of described pin, the vertical section of described otch tilts to pin is inboard, and described pin connects one can will solidify the pin control device that plastics fusion in described hole ejects described lower mold body die face when the die sinking campaign finishes; The die face of described lower mold body has the plastics melt channel that ends buckling die chamber and described plastics fusion injection chamber under the connection.
Described pin control device can adopt following concrete structure to realize: described pin control device comprises a push pedal that is connected in described pin end, and described push pedal is arranged within the cope match-plate pattern and the space between the lower bolster of described lower mold body, and can move axially along guide upright post; Be arranged between cope match-plate pattern and the push pedal and be nested in the spring of described guide upright post; One is fixedly connected on described push pedal, and stretches out the push rod of lower mold body and following mould bases downwards, be fixed in described frame and with the corresponding stopping means in described push rod position.
After the plastics fusion cooling, inject the chamber and the plastics fusion meeting that ends in the buckling die chamber links together at plastics melt channel, plastics fusion, during die sinking, if plastics fusion coupler and the adhesion of plastics melting and solidification body, will pull and draw the only button of injection formed just, influence ends the injection moulding quality of button.After plug structures is set,, during injection moulding, also can there be the plastics fusion in this otch because the pin upper end is provided with the otch of vertical section to the inboard inclination of pin.Reduction along with temperature, the plastics melting and solidification, when the die sinking campaign begins, this pin will hook the plastics melting and solidification body in the plastics fusion injection chamber, even plastics fusion coupler and the adhesion of plastics melting and solidification body, plastics melting and solidification body also can constantly remain on lower mold body with slide fastener under the effect of mould opening force; When the die sinking campaign finished, push rod will lean stopping means, thereby makes push pedal upwards compress spring along guide upright post, and drove pin and move upward, and the plastics fusion is ejected the die face of described lower mold body, and the plastics fusion of being convenient to will solidify in the pin otch is taken out.
As further improvement, the hand-hole that is arranged at described plastics fusion coupler is a bellmouth.Like this, when die sinking, can reduce the die sinking resistance between the plastics fusion of plastics fusion coupler and curing.
