The disassembly and assembly component includes two slide bars 108, a handle 109, a protective layer 110, a fixed frame 111 and a fixed plate 112. The discharge component includes a hydraulic cylinder 114, a connecting member and a top plate 115. The connecting member includes a connecting column block 116 and a connecting sleeve 117. Through the foregoing solution, the problem that the prior art cannot replace the upper and lower molds 106, and if damage occurs, the whole needs to be repaired or replaced, resulting in a high cost is solved.

[0025] For this specific embodiment, the fixed mold base 102 is fixedly connected above the base 101 and is provided with two runners. The fixed seat 103 is slidably arranged above the fixed mold base 102. The upper template 104 is arranged below the fixed seat 103. The mounting frame 105 is fixedly connected to the surface of the upper template 104 and is detachably connected to the fixed seat 103 through a plurality of disassembly bolts 107. The lower mold 106 is slidably connected within the base 101 and is located below the two runners. The disassembly and assembly component is located on the surface of the lower mold 106, and the discharging component is located within the base 101. When processing the rear hub of an automobile, raw materials are injected into the lower mold 106 from the two runners. The fixed seat 103 is pressed downwards to make the upper template 104 enter the fixed mold base 102, and the lower mold 106 is pressed downwards for processing. When replacing the upper template 104, remove the plurality of disassembly bolts 107, take away the mounting frame 105 and the upper template 104, and then install a new upper template 104. When replacing the lower mold 106, reverse-start the discharging component, release the constraint of the lower mold 106 through the disassembly and assembly component, and after pulling out the lower mold 106, install a new lower mold 106 back into the fixed mold base 102.

[0026] Among them, the two sliding strips 108 are slidably connected to the fixed mold base 102 and are fixedly connected to both sides of the lower mold 106. The handle 109 is fixedly connected to one side of the lower mold 106. The protective layer 110 is fixedly connected to the surface of the handle 109. When replacing the lower mold 106, after reverse-starting the discharging component, grasp the handle 109 through the protective layer 110, and then pull out the lower mold 106 under the action of the two sliding strips 108. Under the action of the protective layer 110, the worker does not directly touch the handle 109 and the lower mold 106, and burns will not occur. Under the action of the two sliding strips 108, the sliding of the lower mold 106 is more stable.

[0027] Secondly, the fixed frame 111 is fixedly connected to one side of the fixed mold base 102. The fixed plate 112 is fixedly connected to the lower mold 106 and is slidably connected to the fixed frame 111, and is located on the side away from the handle 109. The fixed frame 111 and the fixed plate 112 are detachably connected by two fastening bolts 113. When installing the new lower mold 106, insert the lower mold 106 into the fixed mold base 102, and the fixed plate 112 moves with the lower mold 106. When the lower mold 106 is completely inserted into the fixed mold base 102, the fixed plate 112 is completely located within the fixed frame 111. At this time, screw the two fastening bolts 113 into the fixed frame 111 and the fixed plate 112, so as to fix the lower mold 106 through the fixed plate 112.

[0028] Meanwhile, the hydraulic cylinder 114 is fixedly connected within the fixed mold base 102. The connecting member is located at the output end of the hydraulic cylinder 114. The top plate 115 is slidably connected to the lower mold 106 and is located above the connecting member. When it is necessary to take out the rear wheel hub of the vehicle, start the hydraulic cylinder 114. The hydraulic cylinder 114 pushes the top plate 115 upward through the connecting member, so that the top plate 115 pushes the rear wheel hub in the lower mold 106 out of the fixed mold base 102.

[0029] Meanwhile, the connecting column block 116 is fixedly connected to the output end of the hydraulic cylinder 114. The connecting sleeve 117 is fixedly connected to the lower part of the top plate 115 and is sleeved on the surface of the connecting column block 116. The connecting column block 116 and the connecting sleeve 117 are detachably connected by a plurality of connecting bolts 118. When the top plate 115 needs to be replaced, reverse-start the hydraulic cylinder 114, unscrew the plurality of connecting bolts 118, then remove the connecting sleeve 117 and the top plate 115. After replacing the new top plate 115, reverse the above operations.

[0030] When processing the rear hub of an automobile, raw materials are injected into the lower mold 106 from the two runners. The fixed seat 103 is pressed downwards to make the upper template 104 enter the fixed mold base 102, and the lower mold 106 is pressed downwards for processing. When replacing the upper template 104, remove the plurality of disassembly bolts 107, take away the mounting frame 105 and the upper template 104, and then install the new upper template 104. When replacing the lower mold 106, start the hydraulic cylinder 114 in reverse, the connecting column block 116 and the connecting sleeve 117 descend, driving the top plate 115 to descend and leave the lower mold 106. Then unscrew the two fastening bolts 113, and grasp the handle 109 through the protective layer 110 to pull out the lower mold 106 from the fixed mold base 102. When installing the new lower mold 106, perform the above operations in reverse; under the action of the protective layer 110, workers do not directly touch the handle 109 and the lower mold 106, and burns will not occur; under the action of the two slide bars 108, the sliding of the lower mold 106 is more stable, avoiding the problem in the prior art that the upper and lower molds 106 cannot be replaced. If damaged, the whole needs to be repaired or replaced, resulting in a higher cost, and achieving the effects of being convenient for replacement and maintenance and reducing costs.

[0032] Please refer to Figures 5-6 , in which Figure 5 is the overall structural schematic diagram of the second embodiment of the present utility model; Figure 6 is the structural schematic diagram of the engaging mechanism of the second embodiment of the present utility model.

[0033] Based on the first embodiment, the automobile rear hub processing mold of this embodiment further includes two engaging mechanisms, and each engaging mechanism includes a convex block 201 and two clamping blocks 202.

[0034] Among them, the mounting frame 105 is provided with two engaging holes. Each of the engaging mechanisms is located in each of the engaging holes and is arranged oppositely. The convex block 201 is fixedly connected to the lower part of the fixed seat 103. Two of the clamping blocks 202 are fixedly connected to the surface of the convex block 201 and are coaxially arranged. When installing the upper template 104, align the two engaging holes of the mounting frame 105 with the two engaging mechanisms, and then push the upper template 104 and the mounting frame 105. The two convex blocks 201 and the four clamping blocks 202 are inserted into the mounting frame 105. The two convex blocks 201 quickly position the mounting frame 105. The four clamping blocks 202 are located in the screw engaging holes, making the mounting frame 105 more stable without shaking, facilitating fixation, and thus quickly and conveniently fixing the mounting frame 105 and the upper template 104, achieving the effect of conveniently installing the upper template 104.
