On the top side of the support base 402, there is a toothed bar 405. On the top side of the toothed bar 405, there is a swing rod 406. On the top side of the swing rod 406, there is a telescopic hinge rod 407 connected by a hinge, and the top end of the telescopic hinge rod 407 is slidably connected to the limit slide rail 408.

[0023] The pneumatic telescopic rod 409 and the hinge base 4010 are symmetrically distributed with respect to the central axis of the swing rod 406.
[0024] In this embodiment, when positioning is required, the pneumatic telescopic rod 409 on one side of the hinge base 4010 outputs power to drive the output end to operate. The operation of the pneumatic telescopic rod 409 causes the swing rod 406 on the toothed bar 405 to operate, and the mechanical fixture 4012 on one side of the pneumatic swing seat 4011 clamps the mold component 2. After clamping, the injection mold box 202 is aligned with the injection mechanism 3. Then, the pneumatic clamping tooth 404 on the inner side of one end of the pair bar 403 positions the swing rod 406.

The carrying roller 106 is wound with a conveyor belt 107. Inside the conveyor belt 107, there is a bearing rod group 108.
[0026] In this embodiment, the driving motor 104 on one end side of the transmission case 103 is then used to output power to drive the output end to operate, so that the transmission wheel set 105 in the transmission case 103 performs output operation, and the output operation of the transmission wheel set 105 enables the mold assembly 2 to run to a suitable position under the mutual cooperation of the carrying roller 106 and the conveyor belt 107.

[0029] The injection mechanism 3 includes an end frame 301, a top seat 302, a hydraulic cylinder 303, a lifting rod 304, a cross beam 305, an alignment cover 306, an injection nozzle 307, a flexible pipe 308, a valve block 309, a compression pump 3010, and a raw material tank 3011. The end frame 301 is arranged above the periphery of the trough-shaped base 102. The top seat 302 is arranged on the top side of the end frame 301, and the lifting rod 304 connecting the output end of the hydraulic cylinder 303 is arranged on the inner bottom side of the top seat 302. The cross beam 305 is arranged below the lifting rod 304.
[0030] In this embodiment, when injection molding is required, the hydraulic cylinder 303 on the top seat 302 is used to output power to drive the output end to operate, so that the hydraulic cylinder 303 outputs power to expand and contract, and the lifting rod 304 drives the cross beam 305 to run to a suitable height.
[0031] An alignment cover 306 for installing the injection nozzle 307 is arranged on the side of the cross beam 305. The valve block 309 is sleeved and connected above the alignment cover 306 through the flexible pipe 308. The output end of the valve block 309 is provided with a compression pump 3010, and the output end of the compression pump 3010 is provided with a raw material tank 3011.
[0032] In this embodiment, the valve block 309 is then opened. After opening, the compression pump 3010 is started to output power to drive the output end to operate, so that the raw material tank 3011 inputs the raw material into the injection nozzle 307 through the pipeline and then into the injection mold box 202 to achieve the injection molding effect.
[0033] The working principle of the optical mold with a quickly switchable runner is as follows: When in use, place the injection mold box 202 on the top side of the insertion slot 201, and place the insertion slot 201 and the injection mold box 202 on the conveyor belt 107. Then, use the driving motor 104 on one end side of the transmission box 103 to output power to drive the output end to operate, so that the transmission wheel set 105 in the transmission box 103 performs output operation. The output operation of the transmission wheel set 105 enables the carrying roller 106 and the conveyor belt 107 to cooperate with each other to move the mold assembly 2 to a suitable position. When positioning is required, use the pneumatic telescopic rod 409 on one side of the hinge base 4010 to output power to drive the output end to operate. The output operation of the pneumatic telescopic rod 409 enables the swing rod 406 on the toothed rod 405 to operate, and the mechanical clamp 4012 on one side of the pneumatic swing seat 4011 clamps the mold assembly 2. After clamping, align the injection mold box 202 with the injection mechanism 3. Then, use the pneumatic clamping teeth 404 on the inner side of one end of the alignment bar 403 to position the swing rod 406. When injection is required, use the hydraulic cylinder 303 on the top seat 302 to output power to drive the output end to operate. The output power of the hydraulic cylinder 303 expands and contracts to make the lifting rod 304 drive the cross beam 305 to a suitable height. Then, open the valve block 309. After opening, use the starting compression pump 3010 to output power to drive the output end to operate, so that the raw material tank 3011 inputs the raw material through the pipeline into the injection nozzle 307 and then into the injection mold box 202 to achieve the injection effect.
