[detailed description of the invention]
For having further understanding to object of the present invention, function and technological means, be now described with reference to the accompanying drawings as follows:
Refer to shown in Fig. 1 to Fig. 3, in a preferred embodiment, the double color mould mechanism of shaping three look products of the present invention, it comprises:
Male model 300, this male model 300 comprises male template 310 and male die core 320, pull bar 330 is provided with in this male template 310 and male die core 320, the avoiding hollow groove 340 corresponding with pull bar 330 is provided with in described male die core 320 and male template 310, described pull bar 330 is provided with step surface 350, and after mould die sinking, this step surface 350 to be stuck in above-mentioned avoiding hollow groove 340 thus to make this pull bar 330 this end be located in male template 310 be stuck in male die core 320;
First master mold 100, this first master mold 100 comprises the first upper mounted plate 110, first stripper plate 120, first caster 130 and the first mother module core 140 sequentially set up, jacking block 150 is provided with in this first mother module core 140, described jacking block 150 is in L-type, empty avoiding is left between this jacking block 150 and first caster 130, elastic component 160 is provided with between this jacking block 150 one end and the first caster 130, described elastic component 160 is spring, this jacking block 150 other end and the first look product 410 support, and this first master mold 100 is provided with first flow 170 with shaping first look product 410;
Second master mold 200, this second master mold 200 comprises the second upper mounted plate 210 sequentially set up, second stripper plate 220, second caster 230 and the second mother module core 240, lower liftout plate 250 and upper ejector plate 251 is provided with in this second caster 230, this upper ejector plate 251 is provided with taper pin 252 to be ejected by the product after shaping, this upper ejector plate 251 is also fixed with return pin 253, this return pin 253 drives above-mentioned lower liftout plate 250 and upper ejector plate 251 to move, the first shutter 260 is provided with between this return pin 253 and above-mentioned pull bar 330, top board pilot pin 290 is also provided with in this second caster 230, this top board pilot pin 290 from above-mentioned lower liftout plate 250 and upper ejector plate 251 through with eject and return time play the guiding role, this top board pilot pin 290 is outer is also provided with top board leader pin bushing 291, this second master mold 200 is provided with the second runner 270 and the 3rd runner 280, described 3rd runner 280 is located in the second caster 230, this second runner 270 does not contact with the 3rd runner 280, second side, master mold sky (second penetrates mould top side) is provided with and penetrates seat, this is penetrated seat and enters glue by the 3rd runner 280 and complete the shaping of the 3rd look product 430.
Wherein, being equipped with material grasping pin 121 in described first master mold 100 and the second master mold 200 makes first flow 170, second runner 270 and the 3rd runner 280 be left to respectively when first time die sinking in the first stripper plate 120 and the second stripper plate 220.
Please again consult shown in Fig. 2, after penetrating mould matched moulds first, shaping first look product 410, the elastic component 160 described in during matched moulds is in confined state, and jacking block 150 supports the first look product 410;
After first look product 410 is shaping, first penetrates mould die sinking, die sinking order is the same with conventional three template die die sinking orders, then the first master mold 100 maintains static, male model 300 rotary motion, now jacking block 150 flicks due to the effect of elastic force by elastic component 160, first look product 410 pushes up down by jacking block 150, the first look product 410 is made to stay in male model 300, prevent sticky first master mold 100 of the first look product 410, this first master mold 100 only has elastic component 160 and jacking block 150 first look product 410 can be ejected, and does not need the complicated ejecting structures such as top board.
Refer to shown in Fig. 3, male model 300 revolves turnback and moves to the second master mold 200 place, and coordinates with the second master mold 200 and become second and penetrate mould, second penetrate mould matched moulds after, second to penetrate mould the same with common double-color mold for this, and the second runner 270 enters the conventional shaping second look product 420 of glue; This second master mold 200 days sides increase by one and penetrate seat and enter glue by the 3rd runner 280 and carried out the shaping of the 3rd look product 430, and described second look product 420 and the 3rd look product 430 can not contact, and are separated by described first look product 410.
After three look product 400 injection mouldings complete, second penetrates mould die sinking, originally male model 300 is subject to the pulling force of injection machine, can not separate owing to being equipped with the second shutter 500 between male template 310 with the second caster 230, now the second stripper plate 220 and the first die sinking of the second caster 230, then the second stripper plate 220 separates with the second upper mounted plate 210, completes front twice die sinking that second penetrates mould.
Refer to shown in Fig. 4, second penetrates mould continues third time die sinking, between male template 310 and the second caster 230, pulling force constantly increases, more than the second shutter 500 coupling mechanism force, second caster 230 separates with male template 310, and because pull bar 330 and male model 300 do not have resistance in die sinking direction, male template 310 moves downward, corresponding pull bar 330 moves upward along avoiding hollow groove 340, until the step surface 350 of pull bar 330 is blocked by avoiding hollow groove 340 simultaneously.
Refer to shown in Fig. 5, after the step surface 350 of pull bar 330 is blocked by avoiding hollow groove 340, male template 310 and the second caster 230 continue die sinking, male template 310 starts drag pull bar 330 and moves downward, pull bar 330 pulls return pin 253 to move downward thus drives upper ejector plate 251 and lower liftout plate 250 to move, start ejecting of master mold side, this upper ejector plate 251 and lower liftout plate 250 start to eject motion, and three look products 400 are ejected.
Refer to shown in Fig. 6, male template 310 and the second caster 230 continue die sinking, when pulling force between pull bar 330 and return pin 253 is more than the first shutter 260 coupling mechanism force, pull bar 330 and the first shutter 260 start separately, and then three look products 400 take out by manipulator.
Compared to prior art, the double color mould mechanism of shaping three look products of the present invention, male model coordinates shaping first look product with the first master mold, then male model revolves turnback and coordinates conventional shaping second look product with the second master mold, and increase by one the 3rd runner in the second master mold, second side, master mold sky increase by is simultaneously penetrated seat and is completed the shaping of the 3rd look product, second look product can not contact with the 3rd look product, the first look product must be had to separate, penetrate mould and second with double color mould first like this and penetrate the board of this two mold of mould and dual-color forming machine and molding cycle just can produce three look products.
