Automatic pick-up actuator of disc injection molding machine

The utility model provides an automatic pick-up actuator of a disc injection molding machine. The automatic pick-up actuator comprises a pneumatic actuator support, a pneumatic actuator and a sensor; the pneumatic actuator comprises an annular rotating cylinder, a pick-up horizontal telescopic cylinder, a pick-up vertical lifting cylinder and a double-vacuum chuck; one end of the pick-up horizontal telescopic cylinder is connected with the annular rotating cylinder, while the other end of the pick-up horizontal telescopic cylinder is connected with the pick-up vertical lifting cylinder, and the pick-up vertical lifting cylinder is connected with the double-vacuum chuck; the pneumatic actuator support is T-shaped and comprises a vertical support and a horizontal support; one end of the vertical support is fixed on the ground, while the other end of the vertical support is connected with the annular rotating cylinder; one end of the horizontal support is fixed with the vertical support, while the other end of the horizontal support is connected with the sensor. The automatic pick-up actuator of the disc injection molding machine has the advantages that injection-molded workpieces in the die do not need to be picked up manually after the upper cover of the die is opened, and instead, the automatic actuator is used for automatically completing the operating of picking up the workpieces; the automatic pick-up actuator is simple in structure and low in cost, and also capable of achieving the effect of improving the production efficiency.
