In this device, the hopper is tilted downward, and the end outlet of the hopper is located directly above the waste collection box. The waste generated during the trimming process is collected and recycled through the groove, hopper and waste collection box. The hopper can speed up the waste collection rate. The main body of the device is rectangular. This setting will cause metal debris to accumulate in the corners around and be difficult to clean. Moreover, the debris inside the collection box is in a loose state, which is not conducive to collection by the staff. Summary of the Invention

[0004] The purpose of the present invention is to provide an aluminum alloy die casting trimming device in order to solve the above-mentioned problems.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: comprising a work cabinet, a mounting frame fixedly mounted on the upper end of the work cabinet, an upper clamping device and a trimming device mounted in the middle of the work cabinet, the trimming device being slidably connected to the mounting frame, a lower clamping device used in conjunction with an upper holding device mounted in the middle of the work cabinet, a compression device and a conveying device for compressing metal scraps mounted inside the work cabinet, a protective device mounted between the compression device and the conveying device, and a taking port for cooperating with the conveying device being opened on one side of the work cabinet;

[0009] Furthermore, the compression device includes a material receiving hopper and a second fixed block, the upper end of the second fixed block is fixedly provided with a second hydraulic telescopic rod, the upper end of the second hydraulic telescopic rod is fixedly connected to the working cabinet, the lower end of the fixed block is fixedly provided with a pressing block, the lower end of the material receiving hopper is hingedly provided with a bottom plate, the lower end of the bottom plate is hingedly provided with a third hydraulic telescopic rod, the conveyor belt is located directly below the bottom plate, and the lower end of the third hydraulic telescopic rod is hingedly provided with the bottom of the working cabinet.

[0010] Furthermore, a slope is provided on one side of the receiving hopper for use with a spiral baffle.

[0011] Furthermore, the lower clamping device includes a motor installed inside the work cabinet through a fixed plate, the output shaft of the motor is installed with a conical plate through a connecting shaft, and a lower clamping plate used in conjunction with the clamping piece is fixedly provided in the middle position of the conical plate.

[0012] Furthermore, a plurality of water filtering holes are provided on the surface of the bottom plate, and reinforcing ribs are fixedly provided on the bottom surface of the bottom plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, when the first hydraulic telescopic rod and the second hydraulic telescopic rod are synchronously moved downward, the annular cover will be driven down, and the connecting rod will be synchronously driven down at the same time. The connecting rod drives the movable rod to move, and the movable rod drives the rack to move to the left. Since the rack is meshed with the gear, it will drive the gear to rotate. Since a one-way bearing is provided between the gear and the rotating shaft, the rotating shaft will not rotate. On the contrary, the movable rod drives the rack to move to the right, so the gear drives the rotating shaft to rotate, and the rotating shaft drives the belt to move, thereby transporting the compressed block at the upper end of the belt to the outside of the work cabinet, thereby facilitating the staff to collect the waste metal and improving work efficiency.

[0015] 2. In the present invention, when the first hydraulic telescopic rod and the second hydraulic telescopic rod are synchronously moved upward, the annular cover will be driven to rise, thereby blocking the metal debris inside the annular cover through the annular cover, and at the same time, the metal debris and coolant are synchronously collected into the receiving hopper through the spiral baffle, thereby facilitating the collection of debris by the staff and effectively avoiding the splashing of metal debris.

[0016] 3. In the present invention, when the first hydraulic telescopic rod and the second hydraulic telescopic rod move downward synchronously, the annular cover will be driven down. The second hydraulic telescopic rod will drive the pressing block to move down through the second fixed block, thereby compressing the metal fragments. A gravity sensor is provided at the upper end of the bottom plate. When it is detected that the compressed metal fragments inside the receiving hopper reach a set weight, the gravity sensor does not work during the compression process, and the third hydraulic telescopic rod contracts, so that the bottom plate rotates open, and the compression block slides to the belt surface under the action of gravity. By compressing the metal fragments into blocks, it is convenient for the staff to recycle them, and the volume increase caused by the fluffy metal fragments can be avoided.

The two sides of the rotating shaft 6062 are rotatably connected to the side plates, which are fixedly connected to the work cabinet 1, and the rack 605 is slidably connected to the side plates. In actual application, when the first hydraulic telescopic rod 601 and the second hydraulic telescopic rod 403 move downward synchronously, the annular cover 302 will be driven downward, and at the same time, the connecting rod 603 will move downward synchronously, and the connecting rod 603 will drive the movable rod 604 to move, and the movable rod 604 will drive the rack 60 5 moves to the left. Since the rack 605 is meshed with the gear 6063, the gear 6063 is driven to rotate. Since a one-way bearing is provided between the gear 6063 and the rotating shaft 6062, the rotating shaft 6062 does not rotate. On the contrary, the movable rod 604 drives the rack 605 to move to the right. Therefore, the gear 6063 drives the rotating shaft 6062 to rotate. The rotating shaft 6062 drives the belt 6061 to move, thereby transporting the compressed block on the upper end of the belt 6061 to the outside of the work cabinet 1, thereby facilitating the collection of waste metal by the staff and improving work efficiency.

[0030] Working principle: first, the workpiece is placed on the upper end of the lower clamping plate, and then the upper clamping device works to stabilize the workpiece. Then, the first hydraulic telescopic rod 601 and the second hydraulic telescopic rod 403 move upward synchronously, which will drive the annular cover 302 to rise, and then the trimming device works. At this time, the motor 502 starts to work, and the motor 502 drives the conical plate 501 to rotate slowly. The trimming device can move laterally according to the state of the workpiece.
