Technical Field

[0001] The utility model relates to the technical field of mold production and processing, in particular to a grinding device for mold production and processing. Background Art

[0002] Mold processing refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. Usually, a mold consists of an upper die and a lower die. The steel plate is placed between the upper and lower dies, and the material is formed under the action of a press. When the press is opened, the workpiece determined by the shape of the mold is obtained or the corresponding waste is removed.

[0003] The existing utility model patent with the authorization announcement number CN220178942U discloses a mold grinding device, which includes a processing table and a back plate detachably connected and fixed to the rear end face of the processing table. A grinding assembly is arranged inside the processing table. A chute is opened on the upper end face of the processing table. A mounting table for fixing the mold is slidably connected to the chute. A transmission assembly fixed to the mounting table is arranged inside the processing table. The grinding assembly includes a grinding vertical plate movably connected to the processing table and a grinding horizontal plate movably connected to the grinding vertical plate. This application can simultaneously polish the upper end face and the circumferential surface of a cylindrical mold through the cooperation of the grinding assembly and the transmission assembly. This polishing process greatly improves the efficiency of mold grinding and polishing. Compared with the traditional manual grinding method, it reduces the manual labor intensity.

[0004] After analysis, it is found that this grinding device fixes the mold through a mounting table with a fixed shape. Limited by the shape of the mounting table, the grinding device cannot grind a part of the mold inside the mounting table, seriously affecting the grinding quality. Even if the unground part is continuously ground later, it greatly increases the processing steps and the operation is cumbersome. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a grinding device for mold production and processing to solve the problems raised in the above background.

[0006] To solve the above technical problems, the utility model provides a grinding device for mold production and processing, which includes an operating table and an I-shaped plate arranged below the operating table. The operating table and the I-shaped plate are connected by four groups of support legs. A grinding plate is slidably arranged on the upper surface of the operating table. A clamping assembly is arranged in the middle of the operating table. The clamping assembly includes a mounting table rotatably connected to the operating table and a cross plate rotatably connected to the mounting table. Four groups of driving rods are connected to the end of the cross plate, and clamping blocks are connected to the end of the driving rods.

[0007] Further, a second motor is connected to the middle of the upper surface of the mounting table, and the output end of the second motor is connected to the cross plate.

[0008] Furthermore, four sets of arc-shaped chutes are provided at the end of the cross plate. The arc-shaped chutes are slidably connected with connecting rods, and a driving rod is connected below the connecting rods.

[0009] Furthermore, four sets of guiding blocks are provided at the four corners of the mounting table. The guiding blocks are hollow, and the driving rod passes through the guiding blocks and is slidably connected with the guiding blocks.

[0010] Furthermore, the clamping block is detachably connected to the end of the driving rod. The end of the clamping block is arc-shaped, and the material is an elastic rubber pad.

[0011] Furthermore, the operating table is slidably connected with a fixing plate through a lead screw. A grinding plate is detachably connected to one side of the fixing plate close to the clamping assembly, and the end of the lead screw is connected to the output end of the first motor.

[0012] Furthermore, a third motor is connected to the upper surface of the I-shaped plate, and the output end of the third motor is connected to the mounting table.

[0013] Furthermore, multiple sets of balls are provided on the inner wall of the guiding block, and four sets of grooves are provided on the driving rod to cooperate with the balls.

[0014] The beneficial effects of the present utility model are as follows:

[0015] By driving the driving rod to move through the cross plate, the clamping block can be used to support and fix the inner embedding of the mold, and the mold can be clamped from the inside of the mold, so that the outer wall of the mold can be effectively polished during the polishing process.

Four groups of driving rods 206 are connected to the end of the cross plate 203. A clamping block 208 is connected to the end of the driving rod 206. The cross plate 203 can drive the driving rod 206 to slide, and the mold can be fixed by the clamping block 208. A third motor 3 is connected to the upper surface of the I-shaped plate 101, and the output end of the third motor 3 is connected to the installation table 201. Starting the third motor 3 can drive the installation table 201 to rotate.
