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 process, and its step is following: 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 said chain tooth section by the drawstring device, make follow-up chain belt get into die cavity through the demoulding, injection kirsite once more, circulation forms a row chain tooth thus, and through electroplating, scald band, slide fastener is processed in assembling at last.There is following problem in prior art processes: 1, conductive filament is woven on the chain belt, through 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 electroplated with the teeth while; And pliability is poor, 2, owing to adopt weaving, to the material property of conductive filament; And preparation method has very high requirement, and at first, the tensile strength of conductive filament, electric conductivity will be got well; When next weaves, will conductive filament be pressed into flat filament earlier, then that flat filament is peripheral around fiber, 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 above-mentioned deficiency that prior art exists, 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, advantages such as attractive in appearance and low production cost.
Realize that the above-mentioned purpose technical scheme is following; The step of this production technology of die-casting zinc alloy zipper is following: two chain belts are under the drawstring device of Die casting machine drives; Parallel entering mold cavity; Meanwhile; Also under the effect of said drawstring device, get into mold cavities at two conductive filaments between two chain belts along two routes that are parallel to chain belt; Have the chain tooth section of conductive filament through matched moulds, injection, cooling forming one, die sinking, eject said 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 get into mold cavity; Carry out next mold pressing casting, circulation forms a row chain tooth thus; Electroplate the back and excise the conductive filament between teeth with screw blade, slide fastener is made in assembling after scalding band.
During practical implementation, described two conductive filaments get into the route of mold cavity between the top and chain belt of teeth, and have the gap with the chain band edge.
During practical implementation, the route that described two conductive filaments get into mold cavity lays respectively on the tooth shoulder axis, chamber of mold cavity to tooth.
During practical implementation, the gap of the tooth of two conductive filaments of said admittance shoulder axis, chamber and chain band edge is the 0.3-0.9 millimeter.
Beneficial effect: compared with prior art; The present invention adopts the technical scheme of conductive filament and chain tooth integral die-cast in die casting chain tooth, thereby has solved the problem of many aspects: the one, and changed and adopted weaving method that conductive filament is arranged on the 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 process, the conductive filament that manufacturing cost is very expensive, thereby production cost is suddenly descended.The 2nd, electroplate the back and adopt the conductive filament between 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, the kirsite teeth after the die casting can be fully and conductive filament fastening, not only contact area is big; And both combine fully; 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 accomplish; Difference is: the one, on Die casting machine, set up a cover conductive filament transport; The traction power of this conductive filament transport can utilize original drawstring device on the Die casting machine; This possibly guarantee the uniformity of conductive filament and chain Tape movement, certainly, will 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 parallel entering mold cavity.
During practical implementation, the route of two conductive filament entering mold cavities 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 frangible not.During practical implementation, the gap of the tooth of two conductive filaments of said admittance shoulder axis, chamber and chain band edge with the 0.3-0.9 millimeter for well.
Job step is following, 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; Parallel entering mold cavity; Meanwhile; Also under the effect of said drawstring device, parallel route (present embodiment adopts tooth shoulder axis, the chamber route in the mold cavity) with chain belt along two gets into 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 said 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 get into 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.
