Description

Technical Field

[0001] The utility model relates to the technical field of material taking manipulators, in particular to a material taking manipulator for an adsorption type injection molding machine. Background Technique

[0002] An injection molding machine, also known as an injection molding machine or an injection machine, is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies. In order to assist the injection molding machine in stably taking materials during the processing of plastic products, a material taking manipulator for an adsorption type injection molding machine is required.

[0003] During the use of traditional material taking manipulators for injection molding machines, most of them dock the bottom of the suction cup with the top of the material, and then use the upward movement of the sliding rod inside the suction cup to assist in evacuating the air between the suction cup and the material. Then, the sliding rod drives the grippers on both sides of the suction cup to rotate, so as to assist the inner wall of the grippers to clamp and feed the material. However, during the use of traditional devices, only the bottom of a single suction cup is docked with the top at the center of the material, resulting in difficulty for the device to stably adsorb the material, and further causing the material to fall before the grippers clamp the material, thus affecting the stable use of the device.
