[background technology]
At present, slide fastener has the branch of plastic fastener, nylon zipper and metal zip fastener, and metal zip fastener has aluminium slide fastener, copper slide fastener and Zinc alloy slide fastener not again.The structure of Zinc alloy slide fastener generally comprises chain tooth, pull head and two chain belts, and two chain belt opposed side edges are embedded a row chain tooth respectively, the engagement of two row chain tooth mutual dislocation, and pull head is stuck on the chain tooth of chain belt relative side.
Existing Zinc alloy slide fastener is to adopt the die casting production technology to make, and its step is as follows: earlier corresponding mould is arranged on the Die casting machine, the chain belt that will be composed of conductive filament again passes mold cavity, injection kirsite behind the matched moulds, and cooling forms chain tooth section; Then, pull out the chain belt of described chain tooth section by the drawstring device, make follow-up chain belt enter die cavity through the demoulding, injection kirsite once more, circulation forms a row chain tooth thus, and through electroplating, scald band, slide fastener is made in assembling at last.There are the following problems for prior art processes: 1, conductive filament is woven on the chain belt, by compression molding process the metallic conduction silk is concatenated into one to the slide fastener teeth, reaches the purpose of transmission current when electroplating, therefore, after electroplating,, not only not attractive in appearance because conductive filament and teeth are electroplated simultaneously, and pliability is poor, 2, owing to adopt weaving, to the material property of conductive filament, and preparation method has very high requirement, at first, the tensile strength of conductive filament, electric conductivity will be got well; When next weaves, conductive filament to be pressed into flat filament earlier, then with flat filament around the fiber periphery, wasting time and energy has increased production cost.3, because conductive filament adopts weaving manner to be located on the band muscle of chain belt, thereby contact area between the two is little, causes poor electric conductivity and influences electroplating quality, and the product aberration after the plating is big, overlay coating thickness and fastness are inconsistent.The patent No. is that 200820145408.8 " the improvement structure of zinc alloy diecasting slide fastener " just belongs to this slide fastener.
[summary of the invention]
For overcoming the prior art above shortcomings, the present invention aims to provide a kind of production technology of die-casting zinc alloy zipper, and it is good to utilize the zinc alloy diecasting slide fastener of this explained hereafter to have pliability, advantage such as attractive in appearance and low production cost.
Realize that the above-mentioned purpose technical scheme is as follows, the step of this production technology of die-casting zinc alloy zipper is as follows: two chain belts are under the drawstring device of Die casting machine drives, the parallel mold cavity that enters, meanwhile, also under the effect of described drawstring device, parallel along two enter mold cavity at two conductive filaments between two chain belts with route chain belt; Have the chain tooth section of conductive filament through matched moulds, injection, cooling forming one, die sinking, eject described chain tooth section after, spur chain belt and conductive filament rapidly by the drawstring device, make the follow-up chain belt of die casting and the conductive filament treated enter mold cavity, carry out next mold pressing casting, circulation forms a row chain tooth thus; With the conductive filament between screw blade excision teeth, slide fastener is made in assembling after scalding band after electroplating.
During concrete enforcement, described two conductive filaments enter the route of mold cavity between the top and chain belt of teeth, and have the gap with the chain band edge.
During concrete enforcement, the route that described two conductive filaments enter mold cavity lays respectively on the tooth shoulder axis, chamber of mold cavity to tooth.
During concrete enforcement, the tooth shoulder axis, chamber of two conductive filaments of described admittance and the gap of chain band edge are the 0.3-0.9 millimeter.
Beneficial effect: compared with prior art, the present invention is in die casting chain tooth, adopt the technical scheme of conductive filament and chain tooth integral die-cast, thereby solved the problem of all many-sides: the one, changed and adopted weaving method that conductive filament is arranged on manufacture craft on the chain belt band muscle for a long time, after adopting this technology, can substitute original special process that adopts with common copper cash and make, the conductive filament that manufacturing cost is very expensive, thereby production cost is suddenly descended.The 2nd, electroplate the conductive filament between back employing screw blade excision teeth, the hard partially problem of slide fastener hardness is readily solved, product is attractive in appearance, pliability good.Moreover, because conductive filament of the present invention is independent of outside the chain belt, kirsite teeth after the die casting can be fully and conductive filament fastening, not only contact area is big, and both are in conjunction with abundant, thereby improved electric conductivity, made that product aberration after the plating is little, overlay coating is evenly firm, helps improving product specification.
[specific embodiment]
Production technology of the present invention adopts the horizontal type die-casting make-up machine to finish, difference is: the one, on Die casting machine, set up a cover conductive filament conveying device, the traction power of this conductive filament conveying device can utilize original drawstring device on the Die casting machine, this may guarantee the uniformity of conductive filament and chain Tape movement, certainly, to guarantee that in operation conductive filament moves under tensioned state.The 2nd, do corresponding improvement to the mold cavity that constitutes by dynamic model and quiet mould, make two conductive filaments can be in two chain band gaps the parallel mold cavity that enters.
During concrete enforcement, the route that two conductive filaments enter mold cavity can be to lay respectively at mold cavity on tooth (intermeshing two teeth) the tooth shoulder axis, chamber separately, and every conductive filament is responsible for all teeth on the chain belt are cascaded.Here also have a problem, that is: the distance between conductive filament and the chain band edge (gap in other words) problem, general principle is that conductive filament is good more the closer to chain band edge (the band muscle limit of chain belt in other words), like this conductive filament frangibility not.During concrete enforcement, the tooth shoulder axis, chamber of two conductive filaments of described admittance and the gap of chain band edge with the 0.3-0.9 millimeter for well.
Job step is as follows, is example with the Die casting machine of a 15-25 ton horizontal automatically (or vertical), through chain belt positioner, conductive filament positioner two chain belts, two metallic conduction silks is arranged on the Die casting machine.After the start, article two, chain belt is under the drawstring device of Die casting machine drives, the parallel mold cavity that enters, meanwhile, also under the effect of described drawstring device, parallel route (present embodiment adopts tooth shoulder axis, the chamber route in the mold cavity) with chain belt along two enters mold cavity at two conductive filaments between two chain belts; Have the chain tooth section of conductive filament through matched moulds, injection, cooling forming one, die sinking, eject described chain tooth section after, spur chain belt and conductive filament rapidly by the drawstring device, make the follow-up chain belt of die casting and the conductive filament treated enter mold cavity, carry out next mold pressing casting, circulation forms a row chain tooth thus; Electroplate the back with the conductive filament between screw blade excision teeth, after scalding band, assemble and make slide fastener, product.
