[0020] like Figure 1 As shown, a support frame 2 is fixedly installed on the lower surface of the processing table 1, and a reinforcing rod 3 is fixedly installed between the inner walls of the support frame 2 to support the device.

[0021] like Figure 1 As shown, a mounting rod 10 is fixedly mounted on the upper surface of the upper template 7 , and the material storage box 11 is fixedly mounted on the top of the mounting rod 10 , which can ensure the stability of the material storage box 11 .

[0022] like Figure 2 ,3 4, the positioning ejection assembly 4 includes a mounting plate 401, two pressing plates 408, and a side plate 411. The mounting plate 401 is fixedly mounted on the side of the processing table 1, and the two pressing plates 408 are movably installed on the support frame 2. The side plate 411 is fixedly mounted between the inner walls of the support frame 2. A positioning rod 402 is fixedly mounted on the lower surface of the mounting plate 401, and a first fixed disk 405 and a second fixed disk 406 are fixedly mounted in the middle of the positioning rod 402. A support rod 407 is slidably mounted in the middle of the positioning rod 402. The support rod 407 is located between the first fixed plate 405 and the second fixed plate 406, and a through rod 403 is fixedly installed on the upper surface of the support rod 407. The top end of the through rod 403 can move through the mold box 5, and a rising plate 404 is fixedly installed on the top end of the through rod 403. The rising plate 404 is slidably installed inside the mold box 5. A connecting rod 409 is fixedly installed between one ends of the two pressing plates 408, and a plurality of return springs 410 are fixedly installed on the surface of the connecting rod 409 at equal intervals, and the top end of the return spring 410 is arranged on the surface of the side plate 411.

[0023] The working principle of this kind of wire protection box processing vertical injection molding machine:

[0024] During use, when the device is performing injection molding, the raw materials are stored in the material storage box 11. At this time, the raw materials in the material storage box 11 will fall from the material storage box 11 to the screw injection barrel 12. At this time, the output end of the hydraulic cylinder 9 is extended and retracted, and the upper template 7 can be driven to move downward, so that the upper template 7 and the mold box 5 are fitted together. At this time, the screw injection barrel 12 works to melt and inject the raw materials, and the raw materials are injected into the mold box 5. When the upper template 7 moves downward, the second fixed plate 406 is pressed on the support rod 407, so that the support rod 407 moves downward, and at the same time, the penetration rod 403 can be moved downward, so that the rising plate 404 is reset to the lowermost surface of the mold box 5, which will not affect the injection of the mold, and when the support rod 407 moves downward, the staff pulls the connecting rod 409 outward at the same time. At the same time, the two pressing plates 408 can be pulled backwards. When the support rod 407 moves to a suitable height, the staff loosens the connecting rod 409, and the pressing plate 408 is reset due to the reset spring 410, so that the pressing plate 408 is pressed on the upper surface of the support rod 407, which plays a role in positioning the support rod 407. After the injection is completed, the output end of the hydraulic cylinder 9 is extended and retracted backwards to move the upper template 7 upwards. When the first fixed plate 405 contacts the lower surface of the support rod 407, the upper template 7 can be separated from the mold box 5. The staff observes whether the model inside the mold box 5 is formed. When the model is formed, the staff pulls the connecting rod 409 backward to separate the pressure plate 408 from the upper surface of the support rod 407. At this time, the output end of the hydraulic cylinder 9 is extended and retracted upward, and the support rod 407 can be driven to move upward. At the same time, the penetrating rod 403 can be driven to move upward, so that the rising plate 404 at the top of the penetrating rod 403 moves upward. At this time, the mold formed inside the mold box 5 can be pushed out. This device can easily take out the mold, thereby improving the efficiency of injection molding.

[0025] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
