The specific embodiment

For describing technology contents of the present utility model, structural feature, the object of reaching and effect in detail, below hereby exemplify embodiment and coordinate accompanying drawing to be explained in detail.

Refer to Fig. 1, a kind of injection mold 1 of the utility model, is arranged on injection moulding machine, comprises a caster 10, a male model plate 20 and a barb apparatus 30, caster 10 in order to male model plate 20 phase matched moulds, barb apparatus 30 is arranged in male model plate 20 and some is exposed male model plate 20 surfaces.

Described caster 10 lower surfaces arrange a mother module core 11, interior at least one runner 12, the runner 12 connection lower surface of mother module core 11 and the upper surfaces of caster 10 of arranging of mother module core 11.

Described male model plate 20 upper surfaces arrange a male die core 21, male die core 21 extends upward the module 22 of a projection, in order to stretch into, in mother module core 11, carry out injection mo(u)lding, male model plate 20 upper surfaces have at least one

mounting groove

23, 23 pairs of upper surfaces of mounting groove form opening, and extend to male die core 21 by male model plate 20 surfaces, in module 22, there is at least one

chute

220, 23 one-tenth of chute 220 and mounting grooves are vertical and be connected, chute 220 and the common groove that is roughly L-type that forms of mounting groove 23, mounting groove 23 arranges an installing hole 230 at relative chute 220 bottom faces, installing hole 230 extends through male model plate 20 bottoms downward vertically, installing hole 230 forms in male model plate 20 bottoms the under shed 231 that a width is larger, under shed 231 forms a support surface 232 with the junction of installing hole 230.

Described barb apparatus 30 comprises a cylinder 31, be arranged at male model plate 20 bottom surfaces and be positioned at installing hole 230 belows, connect gas with injection moulding machine and obtain an air pressure (not shown), there is a telescopic guide rod 32, flexible by air-pressure controlling guide rod 32, guide rod 32 connects a top-facing pin 33, what top-facing pin 33 slided is arranged in installing hole 230, bottom has a limited block 34, limited block 34 is located under shed 231, width is greater than top-facing pin 33, limited block 34 controls with support surface 232 distance that top-facing pin 33 moves, guide rod 32 is to be connected in limited block 34 bottoms, top-facing pin 33 tops compress an inner slide 35, inner slide 35 has a turning arm 350, be arranged in mounting groove 23, turning arm 350 ends have a vertically extending barb slide block 351, be arranged in chute 220, turning arm 350 is roughly orthogonal, adjacent to barb slide block 351 places, one latch 352 is set, latch 352 runs through two relative walls of mounting groove 23, pivot point as inner slide 35, turning arm 350 bottoms have an inclined plane 353 near barb slide block 351 ends, inclined plane 353 extends to this end, so as to when turning arm 350 bottom surfaces and mounting groove 23 offset, the space that inclined plane 353 and mounting groove 23 keep angles, wherein, when turning arm 350 bottom surfaces and mounting groove 23 bottom surfaces offset, turning arm 350 end faces and male model plate 20 and male die core 21 end faces are with high, refer to Fig. 2 and Fig. 3, barb slide block 351 tops have a forming part 3510, in forming part 3510, there is at least one hook groove 3511, runner 12 borders and plastics when forming part 3510 becomes injection moulding jointly with module 22 fill up hook groove 3511, so as to forming the overhead structure (as Fig. 5) of product 40, wherein, when turning arm 350 is horizontally disposed with, 220 of barb slide block 351 and chutes are a spacing distance.

Forming process please refer to Fig. 1, Fig. 4, Fig. 5 and Fig. 6 injection mold 1 is as follows, first after matched moulds, inner slide 35 makes firm being fixed on of barb slide block 351 by male model plate 20 and exerting pressure of male die core 21 in chute 220, (now the position of hook groove 3511 as shown in Figure 5, use the barb that injection moulding forms product 40), the stationary state that inner slide 35 is formed before injection moulding; After injection moulding during die sinking, cylinder 31 is controlled guide rod 32 mortgage turning arms 350 by air pressure, and then make barb slide block 351 put rotation centered by latch 352, until limited block 34 compresses support surface 232, make the hook groove 3511 of forming part 3510 exit the barb (exiting the position of the hook groove 3511 after product 40 as shown in Figure 6) of product 40, so as to taking off smoothly product 40, and inner slide 35 is replied stationary state when upper once matched moulds.

Whereby, injection mold 1 is no matter through moulding several times, barb apparatus 30 still can completely exits product 40 barbs, the utility model is easily manufactured the time of therefore saving many making and mold developing, more save time and the cost of later stage mold repair, and be applicable to multiple kinds of molds, therefore real have practicality and durability, in this proposition utility model application that carries out.
