Specifically, a leaded light post forming die's theory of operation with subassembly cuts: after the light guide column melt is injected into the mold cavity 221, under the action of the overflow groove 224 and the diversion chamber 230, the light guide column melt overflowing from the mold cavity 221 can be recycled through the overflow groove 224 and the diversion chamber 230, so that raw materials can be saved as much as possible, meanwhile, the overflow groove 224 enables the light guide column melt in each mold cavity 221 to form an isolated state, the light guide column melt is prevented from being connected with each other after being cooled and formed, the upper mold 210 is pressed downwards, the upper mold 210 is enabled to move downwards along the first chute 130 and the second chute 140, in the process, because the connecting block 212 and the support rod 316 fixedly installed on the upper mold 210 are fixedly connected, and the sliding plate 315 fixedly connected below the support rod 316 is hermetically slid on the first cooling box 311 and the guide column 312, the sliding plate 315 moves downwards in the first cooling box 311, and because the bottom of the first cooling box 311 is communicated with the pipeline 320, this enables the cooling liquid in the first cooling tank 311 to flow into the pipe 320, and the pipe 320 passes through the lower mold 220 and surrounds the mold cavity 221 (see fig. 13), and then is communicated with the bottom of the second cooling tank 331, so that the cooling liquid at this time respectively surrounds all the light guide column melts along the pipe 320, and finally flows into the second cooling tank 331 under the pressure of the sliding plate 315 pressing down the first cooling tank 311, in this process, the heat of the light guide column melt in the mold cavity 221 is caused to be cooled and formed rapidly, the design of the buckle 318 enables the upper mold 210 and the lower mold 220 to be locked after completing the closed state, and in the process of being locked after the upper mold 210 and the lower mold 220 completing the closed state, because the annular blade 213 mounted at the bottom end of the upper mold 210 has a clearance fit with the outer wall of the mold cavity 221, therefore, the light guide column melt inside the mold cavity 221 and the light guide column melt inside the overflow groove 224 are divided, the molded light guide column is further directly made to be an independent individual body, the upper mold 210 is controlled to automatically reset, after the light guide column is molded, the locking state of the buckle 318 is unlocked, the sliding plate 315 is exerted with upward force by utilizing the gravity of the cooling liquid inside the second cooling box 331 and the elasticity of the elastic member 317, so that the upper mold 210 is automatically lifted and reset, the cooling liquid flows back into the first cooling box 311 from the second cooling box 331 through the pipeline 320, the opening design of the second cooling box 331 is convenient for the volatilization of heat carried in the cooling liquid, when the light guide column needs to be taken out after being molded, the upper mold 210 is automatically reset under the action of the elastic member 317 and the cooling liquid, and the cooling liquid in the second cooling box 331 passes through each mold cavity 221 again in the process, further cooling the formed light guide column, so that the temperature of the formed light guide column is further lowered, and scalding of workers after subsequent taking out is avoided, at the moment, the rotating handle 414 is rotated to drive the connecting shaft 412 to rotate, the first gear 415 is rotated, the two second gears 416 are rotatably installed on the U-shaped shell 411 and meshed with the first gear 415, so that the two second gears 416 rotate synchronously and in opposite directions, the rack 417 is slidably installed on the U-shaped shell 411 and meshed with the two second gears 416, so that the rack 417 slides on the U-shaped shell 411 at the moment, the movable plate 420 is displaced, the fixed plate 435 is fixedly installed on the inner wall of the supporting shell 100, the guide block 434 is fixedly arranged on the fixed plate 435, the guide block 434 is matched with the spiral bar 433, the spiral bar 433 is rotatably installed on the rotating seat 431 through the bearing block 432, the rotating seat 431 is fixedly installed on the fixed plate 435, so that when the movable plate 420 is driven by the rack 417 to ascend, the spiral bar 433 is forced to rotate along with the ascending of the movable plate 420 under the action of the guide block 434, and then the top mold plate 223 fixed at the top end of the spiral bar 433 ascends while rotating, so that the molded light guide column in the mold cavity 221 is subjected to axial and radial forces, the light guide column is taken out of the mold more easily, and the probability of non-smoothness of the side surface of the light guide column is reduced.

It should be noted that the specific model specifications of the upper die 210, the lower die 220, the threaded column 314, the elastic member 317, the first gear 415, the second gear 416, and the rack 417 need to be determined by model selection according to the actual specification of the device, and the specific model selection calculation method adopts the prior art in the field, and therefore details are not described again.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application.
