Specific embodiment
It is with reference to the accompanying drawings and embodiments, new to this practicality in order to illustrate more clearly of the technical solution of the utility model
The technical solution of type is further elaborated, it should be apparent that, some implementations of only the utility model are described below
Example, for those of ordinary skill in the art, without creative efforts, can also be according to these embodiments
Obtain other embodiments.
Referring to figs. 1 to Fig. 4, a kind of auxiliary positioning mechanism of double coloured plastic injection machine mold turn-table device, the mold turn-table device
Including bottom plate 10 and the turntable 20 being rotatably arranged on the bottom plate 10；Auxiliary positioning mechanism includes being set on 20 outer rim of turntable extremely
Few one is preset the matched locating notch 21 of rotation angle and the fastening screw 30 on bottom plate 10 with turntable 20；Work as turntable
After 20 rotate to predetermined angle, fastening screw 30 acts the locating notch 21 for being caught in turntable 20；When turntable 20 move in next step
When making, the action of fastening screw 30 is detached from the locating notch 21 of turntable 20.The auxiliary positioning mechanism and mold turn-table device are original
Inductor is used cooperatively, and during injection molding operation, turntable 20 is rotated with mold by predetermined angle, when inductor senses turntable
20 when being rotated in place, and turntable 20 stops rotating static.At this point, the locating notch 21 on turntable 20 is just right with fastening screw 30
Together, when turntable 20 stops rotating static, the action of fastening screw 30 is caught in the locating notch 21 of turntable 20, and turntable 20 is formed
Mechanical caging ensures that 20 stationary state of turntable is stablized.After mold completes current work step, rotation is needed to next station；
At this point, 30 counteragent of fastening screw is detached from the locating notch 21 of turntable 20, turntable 20 is unlocked, then turntable 20 can carry out
It rotates into and acts in next step.
