[0005] Among them, the snap connection structure between the movable mold top block and the side surface of the boss on the back of the guide plate injection molded part is located on one side of the movable mold top block close to the edge of the guide plate injection molded part, and the auxiliary release suction cup is adsorbed on the front side of the guide plate injection molded part and is located on the other side of the movable mold top block.

[0006] During operation, the main suction cup and the auxiliary release suction cup are respectively adsorbed on the front side of the guide plate injection molded part, and the main suction cup is adsorbed on the middle part of the front side of the guide plate injection molded part, and the auxiliary release suction cup is adsorbed on the front side of the guide plate injection molded part at a position offset toward the main suction cup by a distance relative to the front part of the boss part on the back side of the guide plate injection molded part.

[0007] In the present invention, an area on the guide plate injection molded part located between the movable mold top block and the movable mold ejector pin adjacent to the movable mold top block is an arc-shaped convex surface that is arc-shaped and protrudes toward the front direction of the guide plate injection molded part, and the auxiliary release suction cup is adsorbed on the arc-shaped convex surface position on the front side of the guide plate injection molded part.

[0008] In the present invention, bosses are respectively arranged at the left and right ends of the back side of the guide plate injection molded part, and the movable mold top blocks are in a pair and are respectively pressed against the left and right ends of the back side of the guide plate injection molded part, and snap-on connection structures are respectively arranged between the side surfaces of the bosses at the left and right ends of the back side of the guide plate injection molded part.

[0009] Preferably, the number of the main suction cup and the number of the auxiliary tripping suction cup are two each, and the two auxiliary tripping suction cups are disposed on both sides of the two main suction cups.

When the pick-up force measured by the tension pressure sensor exceeds a set value, the pick-up manipulator will issue an alarm to notify the on-site operator to perform emergency processing.

[0016] A method for removing components of a guide plate removing device with a movable mold top block buckle, comprising the following steps: (1) Preparation: Install the injection mold of the automobile deflector on the injection molding machine, and set up a pick-up robot with a main suction cup and an auxiliary release suction cup next to the injection molding machine, wherein the auxiliary release suction cup is set at the front end of the piston rod of the auxiliary release cylinder of the pick-up robot; (2) Injection molding and mold opening: The injection mold is used for injection molding, and the mold is opened after injection molding, so that the movable mold and the fixed mold are separated, and the guide plate injection molded part stays on the movable mold; (3) Ejection of injection molded parts: The ejector block and ejector pin on the movable mold of the injection mold are driven to eject together, so that the guide plate injection molded part is separated from the cavity surface of the movable mold. After the guide plate injection molded part is separated from the cavity surface of the movable mold, it stays on the ejector block and ejector pin of the movable mold; (4) Preparation for picking up: start the picking up robot provided next to the injection mold, and use the main suction cup and the auxiliary release suction cup at the front end of the picking up robot to suck up the front side of the injection molded part of the guide plate; wherein the auxiliary release suction cup sucks up the curved convex surface of the front side of the injection molded part of the guide plate; (5) Disengagement: The auxiliary release cylinder is driven to move, so that the piston rod of the auxiliary release cylinder moves forward a certain distance. Under the action of the auxiliary release cylinder, the guide plate injection molded part is deformed by force, so that the snap connection structure between the movable mold top block and the side surface of the boss on the back of the guide plate injection molded part is disengaged; (6) Removing parts: The removing robot moves back and removes the guide plate injection molded part from the injection mold; after removing the part, the auxiliary release cylinder is reset.
