The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1, the mould 100 that the utlity model has core-pulling mechanism is used for the plastic components that the moulding inner surface is provided with fluting.This mould 100 with core-pulling mechanism has male model plate 10, be arranged at male model benevolence 20, slide block 31, spring 32, caster 40, the mother module core 50 on the male model plate 10 and be arranged at pilot pin 60 on the caster 40.

See also Fig. 1, Fig. 2 and Fig. 3, described male model benevolence 20 is fixed on the male model plate 10, male model plate 10 upper surfaces in a side of male model benevolence 20 offer a chute 12 and the width that is communicated with chute 12 bottoms greater than the stopper slot 13 of chute 12 width.Mother module core 50 is fixed on the caster 40, can surround a die cavity 11 when mother module core 50 and male model benevolence 20 matched moulds.Chute 12 is communicated with die cavity 11.Male model benevolence 20 1 sides (being the fluting place of corresponding product) offer a short slot 21 that is communicated with die cavity 11.

Slide block 31 has the slider body 311 of a bulk and stretches into piece 312 by what slider body 311 1 end surfaces protruded out, stretches on the piece 312 terminal sides and convexes with projection 314, and projection 314 is provided with the forming blocks 313 of extending to slider body 311 directions.Offer a storage tank 3111 on the other end surface of slider body 311, the upper surface of slider body 311 convexes with a cross section and is the trapezoidal piece 3112 of leading, and slider body 311 upper surfaces offer a guide groove 3113 that tilts downwards.The flank 3114 that extends about both side surface lower end, slider body 311 front and back convexes with.

When this had mould 100 assemblings of core-pulling mechanism, the cunning that the lower end of slide block 31 can move horizontally placed in the chute 12, flank 3114 sliding placing in the stopper slot 13.In addition, be fixed with a slide block baffle plate 70 at the other end of male model plate 10, slide block baffle plate 70 offers a hole slot (indicating among the figure) corresponding to chute 12 places, and spring 32 is placed between the storage tank 3111 of hole slot and slide block 31.Offer a pin-guide hole 41 on the caster 40, pilot pin 60 is placed in the pin-guide hole 41, and is tilted to down the lower surface that stretches out caster 40.

In the present embodiment, acting as of spring 32 do not having external force to do the time spent, replaces slide block 31 to the right, replaces male model benevolence 20 and forming blocks 313 is stretched out outside the die cavity 11 to guarantee slide block 31 right sides.

See also Fig. 2 and Fig. 3, before the matched moulds, slide block 31 is replaced male model benevolence 20 to the right under the elastic reaction of spring 32, stretch into piece 312 and stretch in the short slot 21, and forming blocks 312 is replaced male model benevolence 20 and is not stretched in the die cavity 11.

During matched moulds, caster 40 and male model plate 10 closures, mother module core 50 surrounds die cavity 11 with male model benevolence 20 closures, the lower end of pilot pin 60 is tilted to down stretches into guide groove 3113, slide left thereby drive slide block 31, promptly slide, make forming blocks 312 stretch in the die cavity 11 to the mould outside.

Then, will pour into behind the plastic molting in the die cavity 11, back to be formed cooling die sinking can mold the required fluting of a product in 312 places of the forming blocks in the die cavity 11.During die sinking, caster 40 moves up, and pilot pin 60 tilts to protrude upward guide groove 3113, and drive slide block 31 and slide to the right, slide block 31 slides to the right under the elastic reaction of spring 32 simultaneously, promptly to the mould inner slide, forming blocks 313 is stretched out outside the die cavity 11, can take out the plastic components of forming.

In sum, the mould 100 that the utlity model has core-pulling mechanism is provided with the forming blocks 313 of extending to slider body 311 directions by slide block 31, and under the drive of pilot pin 60, make slide block 31 when mold closing, slide and forming blocks 313 is stretched in the die cavity 11 to the mould outside, slide block 31 is to the mould inner slide when die sinking, make forming blocks 313 stretch out die cavity 11, thereby plastic its inner surface is provided with the plastic components of fluting.
