[detailed description of the invention]
Refer to shown in Fig. 1, it to depict in double injection mould mother plate sliding block mechanism of the present invention the schematic diagram that first penetrates master mold and male model matched moulds state.
Double injection mould mother plate sliding block mechanism of the present invention, with mould die sinking direction for vertical direction, this double injection mould mother plate sliding block mechanism comprises:
First penetrates master mold, it comprises caster 100 and mother module core 110, this caster 100 is fixed with slide block bundle block 200 and block 300, this block 300 is located at the bottom of described slide block bundle block 200, it is the projection 210 at angle of inclination that this slide block bundle block 200 is provided with vertical direction, this projection 210 slides and is located in the chute 410 of slider body 400 one end, this slider body 400 other end connection sliding block enters son 500, this slide block enters son 500 and coordinates shaping first to penetrate product 10 with mother module core 110, flexible member 600 is provided with between this slider body 400 and caster 100, the bottom of this slider body 400 is sequentially provided with draw-in groove 420 and the first tray 700, described first tray 700 is provided with the first drag hook 710,
Second penetrates master mold, and this second is penetrated mother module core that master mold is provided with and slide block and enter son and coordinate shaping second to penetrate product, this second penetrate master mold except mother module core and slide block enter except son all the other structures and described first to penetrate master structure identical;
Two male models, this male model comprises male template 800 and male die core 810, this male template 800 is sequentially provided with holding tank 820 and the second tray 900, described first tray 700 is movable to be located in this holding tank 820, this second tray 900 is provided with the second drag hook 910, and this second drag hook 910 fastens with described first drag hook 710.
Wherein, in order to make projection 210 slide in chute 410 more easily, described projection 210 is T-shaped piece, and correspondingly described chute 410 is T-slot.
Wherein, described flexible member 600 can be spring, can certainly be other flexible member.
Refer to shown in Fig. 2, it to depict in double injection mould mother plate sliding block mechanism of the present invention the schematic diagram that first penetrates master mold and male model first die opening state.After product 10 is penetrated in injection mo(u)lding first, first penetrates master mold and male model die sinking, because the first drag hook 710 fastens with described second drag hook 910, under the pulling force of the first tray 700, second tray 900 and the elastic force effect of flexible member 600, slider body 400 is tilted to lower left (shown in arrow direction) motion along the projection 210 of described slide block bundle block 200, and the first tray 700 departs from described second tray 900 gradually under the drive of slider body 400 simultaneously.
Refer to shown in Fig. 3, it to depict in double injection mould mother plate sliding block mechanism of the present invention the schematic diagram that first penetrates master mold and male model second die opening state.When slider body 400 moves to the first tray 700 and the second tray 900 is separated from, male model continues motion, simultaneously slider body 400 continues to be tilted to lower left along projection 210 and moves under the elastic force effect of flexible member 600, until the draw-in groove 420 of slider body 400 sticks described block 300, slider body 400 is stopped by block 300 and no longer continues motion, and now slide block enters son 500 and under the drive of slider body 400, exited first penetrate the similar structures such as the barb of product 10.
Refer to shown in Fig. 4, it to depict in double injection mould mother plate sliding block mechanism of the present invention the schematic diagram that first penetrates master mold and male model three-part pattern state.After slider body 400 stop motion, male model continues motion, and when after the certain stroke of motion, first penetrates master mold and the complete die sinking of male model.Then, two identical male models respectively rotate 180 °, penetrate male model that master mold coordinates before rotate to second and penetrate master mold place with first, and penetrate master mold coordinate injection mo(u)lding second to penetrate product with second, injection moulding complete second penetrate product after, second penetrates master mold and product is taken out in male model die sinking.Because second penetrates master mold to penetrate the structure of master mold different except mother module core and slide block enter son and first, it is identical that all the other structures all penetrate master mold with first, and therefore male model and second is penetrated operation principle and first that master mold coordinates to penetrate the principle of master mold identical.
Male model and first penetrate master mold or second penetrate master mold matched moulds time; after slider body 400 encounters male template 800; under the effect of mould mold clamping force; slider body 400 is tilted to upper right (arrow rightabout) motion along the projection 210 of slide block bundle block 200; first tray 700 engages gradually with the second tray 900, until complete matched moulds.
Compared to prior art; double injection mould mother plate sliding block mechanism of the present invention; when the product adopting the shaping volume of hot runner larger; first penetrates before master mold or second penetrates master mold and male model die sinking; first penetrates master mold or second penetrates master mold and does not need to carry out die sinking action, can realize the shaping of bicolor plastic product.
