[0002] An automatic retrieving robot for an injection molding machine is an automated device used in the production process of injection molding machines. It can replace manual tasks such as retrieving, turning, placing, and collecting materials, greatly improving production efficiency and safety. This device typically includes a robotic system, a robotic fixture, an automated turning table, and a robot base.

[0003] In the prior art, during the injection molding production process of plastic pallets, the size and weight of the plastic pallets are relatively large. The injection molding machines for producing plastic pallets on the market are generally designed to open and close left and right. After the injection molding is completed, the injection molding machine is separated into left and right, and a material-retrieving aisle appears in the middle. Usually, it is necessary to manually enter the interior of the injection molding machine to retrieve the materials. Although there are various safety protection measures, for the operator, entering the interior of the giant injection molding machine still requires bearing huge safety risks and psychological pressure. For this reason, the utility model proposes an automatic material-retrieving device for an injection molding machine robot to solve the above problems. Utility Model Content

A bearing is installed in the U-shaped frame 12, so that the rotation of the worm shaft 13 is more stable.

[0028] By controlling the rotation of the rollers on both sides of the electric chassis 2, the entire device is moved under the limiting action of the limit rail 10, so that the entire device can be driven into the injection molding machine without manual entry, avoiding safety problems for operators. The support plate 11 is fixedly installed on the electric chassis 2, thereby supporting and fixing the entire device. The hydraulic shearing lift 3 fixedly installed on the upper surface of the support plate 11 can adjust the height of the clamping claw 9, so as to facilitate clamping of plastic pallets at different heights. By starting the motor 14, the motor 14 drives the worm shaft 13 to rotate in the U-shaped frame 12, so that the worm shaft 13 engages with the worm gear 15 for transmission, and then the worm gear 15 drives the threaded rod 5 to rotate.

[0029] A threaded rod 5 is provided in the L-shaped frame 4 for rotation. An upper movable plate 6 is provided on the upper side of the threaded rod 5, and a lower movable plate 7 is provided on the lower side of the threaded rod 5.
