DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] Embodiment 1, refer to Figures 1-3 A processing mould with anti-misplacement structure, including fixedly connected with the fixed die holder 2 of support frame 1 top outer wall.

[0026] In the embodiment, the top four corners of the outer wall of the fixed die holder 2 are welded with positioning shafts 3, the top ends of the four positioning shafts 3 are welded with the same X-shaped support frame 4, the top center of the outer wall of the X-shaped support frame 4 is fixedly installed with a hydraulic cylinder 5, the bottom end of the piston rod of the hydraulic cylinder 5 is fixedly connected with a lifting plate 6, and the bottom outer wall of the lifting plate 6 is fixedly installed with a movable die 7.

[0027] Further, the four corners of the lifting plate 6 are fixedly embedded with linear bearings 8, and the four linear bearings 8 are movably connected with the four positioning shafts 3. Through the precise guiding cooperation of the linear bearings 8 arranged at the four corners of the lifting plate 6 and the four positioning shafts 3, the dislocation of the plastic shell processing mold during the closing process can be effectively prevented, thereby ensuring the forming quality of the plastic shell.
