Abstract
A one-step injection moulding method for forming the upper and lower stops of nylon zipper includes positioning the zipper, closing mould, injection, cooling, opening mould and ejecting product out.
Description
The present invention relates to material production nylon zipper goods, particularly its upper and lower method and device that ends moulding with mecystasis.
Nylon zipper is people's article of living and often using now, and going up of one of its critical component ends and end down, seems simple, and its production technology is not up to expectations always.Once used the metal wire compacting, but outward appearance is relatively poor, and the user is existed unsafe factor and environmental issue; Then use ultrasonic technology instead, compacting nylon is upper and lower to end moulding, but does not overcome shortcomings such as outward appearance is relatively poor, undercapacity yet.A kind of direct use ductile material injection mo(u)lding of rising in recent years makes that nylon zipper is upper and lower to be ended, and has naturally that attractive in appearance, practical, safety, the cost of raw material are low, advantage such as have no side effect.But this explained hereafter efficient is low, percent defective is high, particularly upper and lowerly only must be divided into twice injection moulding, and the location trouble is used two injection machines, all wastes especially during machine with manually.
The present invention overcomes above-mentioned the deficiencies in the prior art part to propose a kind of new forming method, abandon backward side opening door formula type, and the use to ejector retainner plate is improved on vertical injection molding machine, add being used of mold thimble, form upper and lower novel molding method and the device of ending, not only average personal efficiency improves more than ten times, and yield rate reaches more than 98%, and economic benefit is considerable.
Purpose of the present invention can be by reaching by the following technical solutions:
Design, the upper and lower one-step moulding method that ends of a kind of closed type nylon zipper of employing, installation mold and lower position-arresting thimble on vertical injection molding machine have following job step:
A. slide fastener is located; B. matched moulds; C. injection;
D. cooling; E. die sinking; F. eject;
Especially the initial position of described lower position-arresting thimble is arranged to upper surface a little more than lower bolster.
Design, the upper and lower one-shot forming apparatus that ends of a kind of closed type nylon zipper of manufacturing, comprise vertical injection molding machine and mould, according to cyclic program P operation, especially described injection machine is provided with the lower position-arresting thimble, and its upper end is the upper surface a little more than described lower mould plate in starting stage of injection cycle.
With described one-step moulding method and device, be used for the upper and lower manufacturing process of ending of closed type nylon zipper.
Brief description of drawings of the present invention is as follows:
Fig. 1 is the upper and lower one-shot forming apparatus structure chart that ends of closed type nylon zipper of the present invention;
Fig. 2 is a lower bolster duty vertical view;
Fig. 3 is the periodic duty program P flow chart that described one-shot forming apparatus uses.
Below in conjunction with accompanying drawing in detail most preferred embodiment of the present invention is described in detail:
The upper and lower one-step moulding method that ends of a kind of closed type nylon zipper, installation mold 1 and lower position-arresting thimble 21 on vertical injection molding machine have following job step:
A. slide fastener is located; B. matched moulds;
C. injection; D. cooling;
E. die sinking; F. eject;
Especially the initial position of described lower position-arresting thimble 21 is arranged to upper surface a little more than lower bolster 16.
Described steps A has step by step following again:
A1. the section of closing up of slide fastener 7 to be processed is placed the strip groove 11 of mould 1;
A2. make end 71 that slide fastener 7 closes up near lower position-arresting thimble 21, and make separately that the both ends 72 of section place going up of mould 1 to end die cavity position 13.
More than two step by step at present by manually finishing.
Described a2 step by step has following fine division step again:
A21. start position-sensing switch, make cover plate 27 press to the last plane of described groove 11;
A22. the separately section that manually spurs slide fastener 7 makes the end 71 of the section of closing up near lower position-arresting thimble 21;
A23. making separately, the end 72 of section places going up of mould 1 to end die cavity position 13.
At this moment, the slide fastener position fixing process is finished.
Make described lower position-arresting thimble 21 affixed with the top board 23 of injection machine through ejector retainner plate 22;
Described matched moulds step B comprises step by step following again:
B1. start periodic duty program P, make the cope match-plate pattern of mould 1 descending;
B2. eject oil cylinder 25 releases, the parts of this oil cylinder control are in passive running status;
B3. end thimble 21 down and be in free state, descending with cope match-plate pattern;
B4. eject oil cylinder 25 decompressions, drag control assembly, make lower position-arresting thimble 21 descending with injection machine top board 23;
B5. lower position-arresting thimble 21 ends are positioned at when only die cavity 12 bottoms are neighbouring down, and working procedure P makes this thimble keep current position, and carries out locked mode.
Afterwards, die sinking after injection, cooling, lower position-arresting thimble 21 ejects the upper and lower of moulding with the upper position-arresting thimble to be ended, and finishes the one action circulation.At this moment lower position-arresting thimble 21 resides in default initial position, that is, the upper end of lower position-arresting thimble is prepared against when working cycles begins next time, as the witness marker of the slide fastener section of closing up to be processed end 71 a little more than the upper surface 1-5mm of lower bolster.
The upper and lower one-shot forming apparatus that ends of a kind of closed type nylon zipper, comprise vertical injection molding machine 2 and mould 1, according to cyclic program P operation, especially described injection machine 2 is provided with lower position-arresting thimble 21, and its upper end is the upper surface a little more than described mould 1 lower bolster 16 in starting stage of injection cycle.
Described lower position-arresting thimble 21 is positioned at mould 1 time to be ended near die cavity 12 outward flanges, so that establish the position of the section of closing up end 71, makes following this end 71 that only encases after the moulding.
Described lower position-arresting thimble 21 is affixed through ejector retainner plate 22 and injection machine top board 23; After matched moulds begins, according to periodic duty program P, the descending and regression of described lower position-arresting thimble 21 with cope match-plate pattern;
Described lower position-arresting thimble 21 is the regression downwards with liftout tank decompression before locked mode, until its upper end arrive described end near die cavity 12 bottoms down till.Like this, after the beginning injection, end die cavity down and fill with the nylon sizing material, be not subjected to the influence of lower position-arresting thimble 21 substantially.
The upper and lower one-shot forming apparatus that ends of a kind of nylon zipper comprises its upper end a little more than mould 1 lower bolster 16 surfaces, is positioned at and ends die cavity 12 outer peripheral lower position-arresting thimbles 21 under this mould, and this thimble is affixed through ejector retainner plate 22 and injection machine top board 23; Especially this one-shot forming apparatus is in the upper and lower application that ends in making of single-ended monimostyly nylon zipper, to improve work efficiency and yield rate.
The present invention is with respect to the advantage of prior art: adopt the lower position-arresting thimble a little more than the counterdie upper surface, Locked mode retreats and walks to down the only method and apparatus of cavity bottom, and vertical injection molding machine can make the closed type nylon zipper Upper and lowerly end one-shot forming, significantly improve efficient, when reducing machine and cost of labor, have very high economic benefit.
