Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding machine blanking equipment, in particular to an automatic clamping device for blanking of an injection molding machine. Background Art

[0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. In the process of unloading the injection molding machine, the traditional method is to manually remove the unloading, which is time-consuming and labor-intensive, and has low production efficiency. The existing injection molding field is also gradually realizing automated unloading. Multiple plastic products are injection molded at the same time, and usually a fixture is used to unload them one by one, which has low unloading efficiency. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide an automatic clamping device for unloading materials from an injection molding machine, which effectively solves the problem of low production efficiency.

[0004] The technical solution is to include a robotic arm, a mounting plate fixed to the moving end of the robotic arm, a first support rod and a second support rod connected in a forward and backward sliding manner in the mounting plate, a first linear push rod installed at the front end of the mounting plate, the first linear push rod is connected to the front end of the first support rod, a second linear push rod is installed at the rear end of the mounting plate, the second linear push rod is connected to the rear end of the second support rod, a plurality of first negative pressure suction cups are evenly fixed on the first support rod, the plurality of first negative pressure suction cups are connected via a first negative pressure tube, a plurality of second negative pressure suction cups are evenly fixed on the second support rod, the plurality of second negative pressure suction cups are connected via a second negative pressure tube.

[0005] Preferably, a T-shaped slot is provided in the mounting plate, and a sliding block inserted into the T-shaped slot is fixed to the first support rod and the second support rod.

[0006] Preferably, a negative pressure pump is fixed on the mounting plate, and the first negative pressure pipe and the second negative pressure pipe are both connected to the negative pressure pump.

[0007] The utility model has the following advantages over traditional equipment: 1) The structure is ingenious. Through the first linear push rod and the second linear push rod structure, the linear movement of the first support rod and the second support rod can be accurately controlled, so the position of the first negative pressure suction cup and the second negative pressure suction cup can be easily adjusted. The spacing can be adjusted flexibly with high precision and a wide adjustment range, which is helpful for the injection molding machine to clamp or loosen the material; 2) Multiple first negative pressure suction cups and second negative pressure suction cups work simultaneously, which improves the material clamping efficiency of the injection molding machine, saves time and effort, and has a high degree of automation.
