[specific embodiment]
Please jointly consult shown in Fig. 1, Fig. 2 and Fig. 3, wherein Fig. 1 has illustrated caster detent mechanism of the present invention and has illustrated caster detent mechanism of the present invention in another angle schematic diagram of mould matched moulds state in an angle schematic diagram of mould matched moulds state, local enlarged diagram and Fig. 3 that Fig. 2 has illustrated Fig. 1.
Caster detent mechanism of the present invention, be applied in three plate moulds, this three plate mould comprises: upper mounted plate 100, stripper plate 110, caster 120, male model plate 130, upper ejector plate 140, lower liftout plate 150, bottom plate 160 and be located at two foots pad 170 between described male model plate 130 and described bottom plate 160, take mould die sinking direction as vertical direction, in the present embodiment, caster detent mechanism of the present invention comprises:
Two pinball structures 400, it is corresponding being located in two described lateral apertures 320 respectively, this pinball structure 400 has the flexible member 430 in hoodle 420 and the shell 410 in shell 410, shell 410, described flexible member 430 is located at shell 410 inner bottom parts against described hoodle 420, in the present embodiment, this hoodle 420 is steel ball, and this flexible member 430 is spring, in caster 120 die sinkings, before range, described flexible member 430 is in compressive state.
Refer to shown in Fig. 4, it has illustrated caster detent mechanism of the present invention in the schematic diagram of mould the first die opening state.When after three plate mould die sinkings, when originally the male model side of mould is subject to the pulling force of injection machine, between male model plate 130 and caster 120 due to shutter 180 being housed, and between stripper plate 110 and caster 120 without any link and hinder, at this moment under the pulling force effect of injection machine, first stripper plate 110 separates with caster 120, caster 120 is along with male model plate 130 together motion backward, caster 120 drives board 300 to move simultaneously, while moving to setpoint distance, caster 120 is blocked by the limited block of lower link bar (not shown).
Refer to shown in Fig. 5, it has illustrated caster detent mechanism of the present invention in the schematic diagram of mould the second die opening state.After caster 120 is blocked by lower link bar limited block, under the pulling force effect of injection machine, caster 120 drives board 300 to continue motion backward with injection machine, lower link bar is also driven like this, lower link bar drives again stripper plate 110 setpoint distance that moves, to stub bar is laid, after setpoint distance has moved, lower link bar and all stop motions of caster 120, the now draw-in groove 210 on positive corresponding the guide rod 200 of pinball structure in board 300 400, flexible member 430 in pinball structure 400 stretches hoodle 420 is ejected, and this hoodle 420 is stuck in draw-in groove 210 caster 120 is positioned, only in the time that external force is greater than the screen resilience of this flexible member 430, hoodle 420 just can depart from draw-in groove 210 returns, and the screen resilience of caster 120 is not enough to flexible member 430 to push back, thereby prevent that rebound phenomenon from appearring in caster 120.
Refer to shown in Fig. 6, it has illustrated caster detent mechanism of the present invention in the schematic diagram of mould three-part pattern state.When after lower link bar and caster 120 stop motions, injection machine continues motion backward, and pulling force constantly increases, and exceedes shutter coupling mechanism force.Caster 120 separates with male model plate 130, slack while being separated into setpoint distance.
In the time of mould matched moulds, under the promotion of injection machine, the lateral movement of male model side direction master mold, because caster 120 is positioned, has guaranteed male model plate 130 and the first matched moulds of caster 120; Then injection machine continues to promote mould matched moulds, because the pressure of injection machine is far longer than the screen resilience of flexible member 430, hoodle 420 departs from draw-in groove 210 and is forced to push back, caster 120 starts action, caster 120 does revert action jointly with male model plate 130, until the complete matched moulds of mould starts injection mo(u)lding next time.
The foregoing is only preferred embodiment of the present invention, architectural feature of the present invention is not limited to this, for example, in other embodiment of the present invention, in order to prevent the normal work of this three plate mould of draw-in groove 210 effect of attrition, on this guide rod 200, can establish two draw-in grooves 210, wherein a draw-in groove 210 gives over to this board 300 for subsequent use, corresponding with this two draw-in groove 210 and is provided with four lateral apertures 320, and wherein two lateral apertures 320 give over to for subsequent use.
Compared to prior art, master mold detent mechanism of the present invention, in the time that range is arrived in caster 120 die sinkings, flexible member 430 ejects hoodle 420, hoodle 420 is stuck in draw-in groove 210 caster 120 is positioned, thereby while having solved in three plate moulds male model plate 130 with caster 120 die sinking there is the phenomenon of resilience in caster 120, guarantee that caster 120 opening strokes are consistent with design load, facilitate the taking-up of stub bar, and in the occasion that master mold position is had to requirement, insert molding as automatic in robot, if when setting program is master mold location, can satisfy the demands and can realize the fully-automatic production of robot.
