[0020] The specific implementation of the present utility model will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-3 As shown, a fixture for mold processing includes a box body 1, an electric turntable 2 is welded to the lower part of the box body 1, and a clamping assembly 3 is fixedly installed on the upper part of the electric turntable 2;

[0022] The clamping assembly 3 includes a clamping table 301 fixedly mounted on the upper part of the electric turntable 2, a support plate 302 is welded to the upper center of the clamping table 301, a slide bar 303 is welded to the lower center of the support plate 302, a sliding sleeve 304 is sleeved on the slide bar 303, first rotating supports 305 are fixedly mounted on both sides of the sliding sleeve 304, and a first connecting rod 306 is rotatably connected to the outer side of the first rotating support 305, second rotating supports 307 are fixedly mounted on both sides of the clamping table 301, and the inner rotating support 307 of the clamping table 301 is rotated. A connecting frame 309 is installed, and a hydraulic push rod 308 is installed in the lower part of the clamping table 301. Through the setting of the hydraulic push rod 308 and the design of the connecting frame 309, the clamping force and stability of the clamp can be better controlled, thereby improving the processing quality. The middle part of the connecting frame 309 is rotatably connected to the first rotating support 305, the extended end of the connecting frame 309 is rotatably connected to the first connecting rod 306, and the two ends of the lower part of the connecting frame 309 are rotatably connected to the two ends of the hydraulic push rod 308. The design of the connecting frame 309 can more effectively transmit the clamping force, improve the clamping efficiency and stability of the clamp, a clamp head 311 is slidably installed on the clamping table 301, a through hole 314 is opened in the middle of the inner side of the clamp head 311, and the second connecting rod 310 is rotatably connected to the two sides of the clamp head 311.
