Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

It should be noted that it can be directly on another component when component is referred to as " being fixed on " another component Or there may also be components placed in the middle.When a component is considered as " connection " another component, it, which can be, is directly connected to To another component or it may be simultaneously present component placed in the middle.When a component is considered as " being set to " another component, it It can be and be set up directly on another component or may be simultaneously present component placed in the middle.Term as used herein is " vertical ", " horizontal ", "left", "right" and similar statement for illustrative purposes only.

Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein includes Any and all combinations of one or more related listed items.

Referring to Fig. 1, in one preferred embodiment of the utility model zipper latch, a kind of zipper latch 100 includes straight body 10 And two fin 20.

Straight body 10 includes interconnecting piece 11 and two plug divisions 12.Two plug divisions 12 be fixed on the opposite sides of interconnecting piece 11 and with Interconnecting piece 11 forms receiving portion 13.Two plug divisions 12 are parallel to each other and perpendicular to interconnecting pieces 11.Each fin 20 is fixed on grafting Portion 12.Fixed part 21 is formed between two fins 20, fixed part 21 is connected to receiving portion 13.It is parallel to each other between two fins 20.Two The distance between fin 20 is less than the distance between two plug divisions 12.Each fin 20 is parallel with plug division 12.Fin 20 and insert Socket part 12 is located at Different Plane.Fin 20 with a thickness of 0.35-0.5mm.The length of fin 20 is smaller than the length of plug division 12 0.5-1mm.The width of fin 20 is 2-3mm.

When using zipper latch 100, rubberizing is contained in fixed part 21 and receiving portion 13, and fin 20 encases rubberizing, completes patch After glue assembling, is pushed on the plug division 12 of straight body 10 and fin 20, tackle two-winged shots on plug division 12 and beat 3-6 on fin 20 A point fixes rubberizing.Since the position that rubberizing interts is encased by fin 10 completely, avoids rubberizing and is contacted with the direct of pull head, The cracking phenomena for avoiding rubberizing in round-trip intert in this way, substantially increases the service life of zipper.

Please continue to refer to Fig. 2 to Fig. 8, the utility model further relates to a kind of zipper latch mold 200, the zipper latch mold 200 for manufacturing above-mentioned zipper latch 100.Zipper latch mold 200 includes upper cores 210, lower mode 220 and core pulling 230.On Mode 210 is equipped with nozzle 211 and several casting slots 212.Each casting slot 212 is equipped with straight body slot 213, wing tank 214 and guidance Slot 215.Wing tank 214 is between straight body slot 213 and guiding groove 215.Wing tank 214 and straight body slot 213 and guiding groove 215 connect It is logical.Lower mode 220 is equipped with several casting slots 221.Core pulling 230 includes grip part 231 and the type core positioned at 231 end of grip part 232.Type core 232 includes straight body core 233, airfoil core 234 and guide portion 235.Straight body core 233 and guide portion 235 are individually fixed in The opposite sides of airfoil core 234.

When using above-mentioned zipper latch mold 200, upper cores 210 are closed up with lower mode 220, the casting slot of upper cores 210 212 are located in type chamber with the 221 shape forming cavity of casting slot of lower mode 220, the type core 232 of the core pulling 230, type core 232 and type Mold cavity is formed between chamber.Liquid material enters mold cavity by nozzle 211.After zipper latch 100 is cooled and shaped, to core pulling 230 grip part 231 applies external force, slides type core 232 along guiding groove 215 by guide portion 235, makes type core 232 and zipper Bolt 100 separates.

The zipper latch 100 of the utility model increases the stationary plane of zipper latch 100 and rubberizing by increasing fin 20 Product keeps zipper latch 100 and rubberizing fixation stronger.And fin 20 has encased the interspersed position of rubberizing, avoids rubberizing With directly contacting for pull head, the cracking phenomena of rubberizing is avoided in round-trip intert in this way, substantially increase zipper uses the longevity Life.

It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the utility model claims Within the scope of.
