Abstract
The present invention relates to a zipper and its manufacture method. In particular, it is a kind of hook-shaped alternative teeth injection moulded zipper. The front surface of the described zipper every tooth is made into the hook form, and its back surface is made into the curved form, after the zipper tooth are engaged, the engagement is a standard alternative teeth arrangement, and between the zipper teeth a mutual engagement zone is retained. Said invented manufacture method adopts a 'zigzag type face-parting technique'. Said invention also provides the concrete steps of said method.
Description
Technical field
The present invention is a kind of slide fastener and preparation method, particularly a kind of hook-type malposed tooth injection molding zipper and preparation method.
Background technology
The malposed tooth injection molding zipper is at the beginning of the slide fastener industry is introduced the injection molding zipper technology, and is once all the fashion, adopts dislocation to arrange between positive and negative (upper and lower) of every miaow tooth of its slide fastener, and utilizes dislocation to form mutual miaow tooth engagement.
The malposed tooth structure requires very strict to the high gap of mouth of zipper head, because the dislocation plane of action of upper and lower miaow tooth is positioned at same plane (the same die joint of mould), so when engagement, the field of conjugate action there is no the gap each other in theory, so there is the shortcoming of poor, the light slippery difference of slide fastener pliability in the malposed tooth slide fastener.
When (slide fastener wearing and tearing when fit clearance is bigger on the high direction of mouth of slide fastener and pull head, due to pull head distortion and the pull head mismachining tolerance), when the slide fastener drawing, just easily take place to block dental phenomenon between the miaow tooth, existence because of the card dental phenomenon, make slide fastener that the bad and disengagement that causes of engagement (upper and lower to) take place, be commonly called as quick-fried tooth.
Because of the limitation of malposed tooth structure, along with the appearance of miaow head location new construction, malposed tooth few production to the utmost at present.
But when adopting special miaow thread form shape, when particularly producing slide fastener with the asymmetric special miaow thread form shape in the left and right sides, reason because of moulding, can not adopt the structure of miaow head location, and can only adopt traditional malposed tooth structure, and this makes the dependability of special miaow shape slide fastener, light slippery, pliability all relatively poor, the production difficulty increases, Just because of this, special miaow shape slide fastener is used actually rare in actual production.
Summary of the invention
The objective of the invention is for, the Yi Kami problems such as (quick-fried teeth) poor that overcome that some that exist on the special miaow shape injection molding zipper technology are difficult to overcome and develop a kind of novel hook-type malposed tooth injection molding zipper and preparation method as light slippery, pliability.
The present invention realizes as follows:
Slide fastener miaow thread form shape of the present invention, its obverse and reverse is different, it is the positive hook shape that is, its reverse side is the garden camber, positive hook shape is the garden camber that little by little carries out the transition to reverse side, and miaow tooth engagement back is the malposed tooth layout of standard, maintains the district that is meshing with each other between the miaow tooth.
The preparation method of hook-type malposed tooth injection molding zipper of the present invention, taked " meander configuration die joint " technology, owing to adopted the meander configuration die joint, make the miaow tooth after the moulding, at above-below direction one high low head is arranged, when the slide fastener drawing, gap between slide fastener and pull head is generally 0.2mm-0.3mm, when two chain teeth are each positioned at the high-low limit position in pull head, under the drawing state, also can mesh smoothly, and can not block dental phenomenon.
In meander configuration die joint shape is selected, interior inclined-plane (being positioned at miaow tooth central authorities) should be chosen in the thinnest connecting place of upper and lower half miaow tooth, and outer inclined-plane (between two miaow teeth) should be chosen in the gap between the miaow tooth, so just can make the inclined-plane miaow thread form shape not constituted influence.
It is very important whether the quality of die joint produces burr, overlap during to injection moulding, and in order to ensure the adaptation of the upper and lower intermode of die joint, the meander configuration die joint should adopt the silk thread excision forming of being careful.
Consider that die width is generally about 100mm, can require to adopt bigger wire cutting machine type during this online cutting and increase line cutting man-hour, so miaow tooth moulding section should adopt the in-mode inserts formula, the width of mold insert is more appropriate with 40-50mm, for avoiding anti-heat treatment distortion, the technology in reprocessing meander configuration die joint and miaow tooth form chamber after the mold insert employing heat treatment.
Good effect of the present utility model is as follows: slide fastener of the present invention is when drawing, there is not the positively engaging phenomenon in its region of engagement, so light slippery is splendid during drawing, upper and lower between the slide fastener miaow tooth after the drawing simultaneously, left and right direction all is provided with fit clearance, so pliability significantly improves, avoided strong sense fully by the malposed tooth slide fastener existence of common process production.
Description of drawings
Fig. 1 is the front miaow tooth form figure of slide fastener of the present invention.
Fig. 2 is the reverse side miaow tooth form figure of slide fastener of the present invention.
Fig. 3 is the miaow tooth region of engagement schematic diagram of slide fastener of the present invention.
Fig. 4 is mould meander configuration die joint figure of the present invention.
Among the figure, miaow tooth front, 2 miaow tooth reverse side, 3 miaow tooth region of engagements, 4 meander configuration die joints, 5 high low heads.
The specific embodiment
As shown in Figure 1, miaow tooth positive 1 is a hook shape; As shown in Figure 2, miaow tooth reverse side 2 is the garden camber.The hook shape in miaow tooth front 1 is the garden camber that little by little carries out the transition to miaow tooth reverse side 2, and miaow tooth engagement back is the malposed tooth layout of standard, as shown in Figure 3, maintains the district 3 that is meshing with each other between the miaow tooth.
As shown in Figure 4, the preparation method of hook-type malposed tooth injection molding zipper of the present invention has been taked " meander configuration die joint " technology, curved portion is a mould meander configuration die joint 4 among the figure, owing to adopted meander configuration die joint 4, make the miaow tooth after the moulding, the high low head 5 of above-below direction 0.24mm is arranged.
In meander configuration die joint 4 selected, interior inclined-plane (being positioned at miaow tooth central authorities) should be chosen in the thinnest connecting place of upper and lower half miaow tooth, and outer inclined-plane (between two miaow teeth) should be chosen in the gap between the miaow tooth.
The meander configuration die joint should adopt the silk thread excision forming of being careful.
Miaow tooth moulding section should adopt the in-mode inserts formula, and the width of mold insert is more appropriate with 40-50mm.
Mold insert should adopt the technology of reprocessing meander configuration die joint and miaow tooth form chamber after the heat treatment.
