Support plates are symmetrically arranged at the midpoint of both ends of the top of the mold base. A placement plate is arranged on the top of the two sets of support plates. Mounting blocks are symmetrically arranged at the midpoint of both sides of the top of the mold base. This utility model device, through the cooperation of the placement plate, first sliding rod, sleeve block, rotating handle, clamping block, bidirectional threaded rod, second sliding rod, mounting block, clamping rod, and support plate, can clamp the mobile phone shell, allowing for more complete polishing and preventing incomplete polishing due to instability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 As shown, a plastic casing polishing mold for precision mobile phones includes an operating table 1, support feet 4, mounting columns 5, cylinders 6, and mounting shells 7. It also includes a casing fixing assembly 2 and a casing polishing assembly 3. The support feet 4 are fixedly installed on the lower part of the operating table 1, the mounting columns 5 are fixedly installed on the upper part of the operating table 1, the cylinders 6 are fixedly installed on the upper part of the mounting columns 5, and the mounting shells 7 are located on the lower part of the mounting columns 5. The movable end of the cylinder 6 passes through the upper part of the mounting columns 5 and is fixedly connected to the outer surface of the mounting shells 7. The casing fixing assembly 2 is located on the upper part of the operating table 1, and the casing polishing assembly 3 is installed inside the mounting shells 7. The designed casing fixing device can simultaneously position and fix multiple mobile phone casings to be polished, which is convenient for subsequent polishing.

[0025] like Figure 2As shown, the housing fixing assembly 2 includes a movable plate 201 disposed on the upper part of the operating table 1. The movable plate 201 has a placement groove inside, and a slide rod 202 slides inside the placement groove. An arc-shaped groove 203 is formed on the upper part of the operating table 1, and a rod 204 slides inside the arc-shaped groove 203. A rubber block 205 is rotatably connected to the top of the rod 204, and the lower part of the rod 204 is fixedly connected to the outer surface of the slide rod 202. A bidirectional lead screw 2 is rotatably connected between the inner and outer walls of the movable plate 201. 06. The slide rod 202 is internally screwed onto the outer surface of the double-acting screw 206. A knob is fixedly installed at one end of the double-acting screw 206. A sliding groove is provided on the upper part of the operating table 1. A threaded rod 207 is rotatably connected inside the sliding groove. A moving block 208 is screwed onto the outer surface of the threaded rod 207. The upper part of the moving block 208 is fixedly connected to the lower part of the moving plate 201. An elongated groove is provided on the upper part of the operating table 1. A guide rod 209 is fixedly installed inside the elongated groove. The outer surface of the guide rod 209 slides... The device has a slider, the lower part of which is fixedly connected to the lower part of the moving plate 201. A crank is installed on the side wall of the operating table 1, one end of which is fixedly connected to one end of the threaded rod 207. When the user polishes the phone case, the user places the phone case to be polished on the moving plate 201. At this time, the user rotates the knob to drive the bidirectional lead screw 206 to rotate. As the bidirectional lead screw 206 rotates, the sliding rods 202 on both sides move away from each other. As the sliding rods 202 move away from each other, the rods 204 move away from each other. As the rods 204 move away from each other, the rubber blocks 205 on both sides move away from each other and are locked in place on both sides of the phone case. The internal fixing method can reduce the problem of paint peeling caused by the internal and external fixing of the phone case. At the same time, as the sliding rods 202 move away from each other, multiple rods 204 and multiple rubber blocks 205 can simultaneously limit multiple phone cases, thereby alleviating the problem that multiple phone cases cannot be fixed at the same time, which requires repeating the single fixing process and greatly reduces work efficiency.

[0026] like Figures 1-5As shown, the housing polishing assembly 3 includes a dual-axis motor 301 fixedly installed inside the mounting housing 7. A shaft 302 is rotatably connected to the side wall of the mounting housing 7. A side bevel gear 303 is fixedly installed on the outer surface of the shaft 302. A drive shaft 304 is rotatably connected between the inner and outer walls of the mounting housing 7. A lower bevel gear 305 is fixedly installed at the upper end of the drive shaft 304, and the lower bevel gear 305 meshes with the side bevel gear 303. The output end of the dual-axis motor 301 is fixedly connected to one end of the shaft 302. The side wall of the mounting housing 7 has heat dissipation holes. A polishing wheel 306 is fixedly installed at the lower end of the drive shaft 304. As the phone case is fixed on the moving plate 201... At this point, by turning the crank, the moving block 208 is moved. As the moving block 208 moves, the moving plate 201 moves to the polishing wheel 306. Then, by activating the cylinder 6, the mounting shell 7 is adjusted in height. After the adjustment is completed, the dual-axis motor 301 is activated, which drives the shaft 302 to rotate. As the shaft 302 rotates, the side bevel gear 303 rotates. As the side bevel gear 303 rotates, the lower bevel gear 305 rotates. As the lower bevel gear 305 rotates, the transmission shaft 304 rotates. As the transmission shaft 304 rotates, the polishing wheel 306 rotates. As the polishing wheel 306 rotates, the exterior of the phone case can be polished.

[0027] In use, when polishing a phone case, the user places the phone case to be polished on the moving plate 201. Turning the knob rotates the bidirectional lead screw 206, causing the sliding rods 202 on both sides to move away from each other. This movement in turn causes the rods 204 to move away from each other, and the rubber blocks 205 on both sides to move away from each other, securing them to the sides of the phone case. This internal fixing method reduces paint chipping caused by internal and external fixing of the phone case. Once fixed, the dual-axis motor 301 is activated, causing the shaft 302 to rotate. This rotation of the shaft 302 drives the side bevel gear 303, which in turn drives the lower bevel gear 305. The lower bevel gear 305 then drives the transmission shaft 304, which in turn drives the polishing wheel 306. The rotation of the polishing wheel 306 polishes the exterior of the phone case.
