[0002] Castings refer to the process of pouring liquid metal into a mold cavity with a shape and size that is suitable for the part, and then cooling and solidifying it to obtain a blank or part. The molded products need to go through the step of cutting the gate. The common gate removal method is physical cutting, including thermal cutting methods such as flame, plasma, laser, and cold cutting methods such as band saws, circular saws, and milling cutters. The most commonly used method is to use a vertical band saw to remove the gate of a casting. When removing the gate of existing castings, most workers need to manually push the workpiece to remove the gate.

Especially for smaller castings, it is inconvenient for workers to manually pick up, so that the workers' hands can easily touch the saw belt after fatigue. At the same time, when cutting the gate, the product may be damaged due to the operator's mistakes. Therefore, a device that can solve the above problems, reduce labor intensity, realize standardized gate cutting, and improve production efficiency is now needed. Utility Model Content

[0034] The working principle and use process of this utility model:

[0035] When in use, the worker places the upper cover workpiece 17 between the lower clamping plate 601 and the upper clamping plate 602, and makes the upper gate of the upper cover workpiece 17 face outward, and the bottom end of the upper cover workpiece 17 is located in the placement groove 603, and the electric telescopic rod 604 drives the upper clamping plate 602 to move downward, and the upper cover workpiece 17 is clamped and fixed between the upper clamping plate 602 and the lower clamping plate 601.

Under the drive of the threaded screw 5, the slider 4 moves to the front of the grinding assembly 9 and stays for a while. Since the gate of the upper cover workpiece 17 has cut-off marks, the convex The raised gate will squeeze the grinder 904, and the squeeze of the grinder 904 will cause the movable column 902 to slide in the pressure regulating cylinder 901, and the spring 903 will be compressed. As the grinder 904 grinds, the gate of the upper cover workpiece 17 gradually becomes flat, and the spring 903 gradually returns to its initial state. During this period, the vacuum cleaner 16 will remove the dust generated during grinding through the dust suction plate 15. After the grinding process is completed, the slider 4 moves to the front of the unloading wheel 13 under the drive of the threaded screw 5. At this time, the electric telescopic rod 604 drives the upper clamping plate 602 to lift, and the upper cover workpiece 17 loses the clamping force. The second motor 12 drives the unloading wheel 13 to rotate, and the unloading plate 14 on the unloading wheel 13 will move the upper cover workpiece 17, causing the upper cover workpiece 17 to break away from the placement groove 603 and fall into the placed workpiece box, and then the clamping assembly 6 moves back to the initial position, waiting for the next workpiece to be processed.
