Mechanism for automatically detecting complete demolding of product

The utility model discloses an automatic detection product complete demolding mechanism and relates to the field of injection molding product detection. The device comprises an air cylinder, an air cylinder support, a clamp, a relay set, an infrared light emitting element and an infrared light receiving element. One end of a clamp for clamping materials is connected with a piston rod of an air cylinder fixed on the air cylinder bracket; the infrared light emitting element and the infrared light receiving element are oppositely arranged, the clamp is driven by the piston rod to go in and out between the two supporting arms, the mechanism detects whether a product is completely demolded or not through the infrared emitting element and the infrared light receiving element, if the product completely cuts off an infrared loop, it shows that the product is complete, and if not, it is considered that the product has defects. By utilizing the detection mechanism, whether the product is completely separated from the m
