[0031] like Figure 1 As shown, an injection molding machine that can rotate 360° for loading and unloading includes an injection molding machine body 5, a 360° rotating platform 1 is installed at the center position of the upper end of the injection molding machine body 5, and a support column 2 is installed above the 360° rotating platform 1. The support column 2 can rotate 360° relative to the injection molding machine along with the 360° rotating platform 1, thereby increasing the activity space during the loading and unloading process and thus improving work efficiency.

[0032] A lifting arm 3 is installed on the top of the support column 2, and the other end of the lifting arm 3 extends to the external space of the injection molding machine body 5, which is convenient for transporting molds, materials, etc. A crane 4 is slidably installed on the lifting arm 3 for lifting materials.

[0033] like Figure 2-3As shown, the 360° rotating platform 1 includes a fixed base 101, on which a rotating track 102 is fixedly mounted, and a rotating body 103 is rotatably mounted at the inner center position of the rotating track 102. A transmission gear 104 is in frictional contact with the outer wall of the rotating track 102, and the transmission gear 104 is meshed with the outer gear ring 107 on the rotating track 102. That is, the present application adopts a gear transmission, and its transmission efficiency is very high, usually reaching more than 98%. Therefore, during the energy transfer process, there is only a small amount of energy loss, which is very useful in the hoisting operation of the injection molding machine that requires precise control of the speed and torque, ensuring the stable operation of the mechanical equipment. The transmission gear 104 is driven to rotate by a reduction motor 105, and the reduction motor 105 is mounted on a support connecting plate 106, and the other end of the support connecting plate 106 is fixedly connected to the hoisting arm 3. The support connecting plate 106 is an L-shaped structure, and the reduction motor 105 is installed on the upper end surface of the horizontal distribution thereof, and is protected by the vertical distribution structure to prevent the reduction motor 105 from being damaged after the crane 4 over-travels, and also to play the role of beautiful appearance. In addition, the reduction motor 105 in the present application adopts a forward and reverse motor, which is convenient for frequent changes in the direction of rotation during transportation, improving efficiency while reducing unnecessary operating steps. Specifically, the reduction motor 105 is started, and the transmission gear 104 rotates on the rotating track 102 to perform a rotational motion. During rotation, the top lifting arm 3 is driven by the support connecting plate 106 to perform a 360° rotational motion with the central axis of the rotating track 102 as the center of the circle, meeting the large-space operation of the injection molding machine loading and unloading process, improving efficiency, and reducing the labor intensity of workers.

[0034] like Figure 4 As shown, the lifting arm 3 includes an arm body 301, and a reinforcing rib 302 is integrally formed on the upper end surface of the arm body 301 to strengthen the force-bearing capacity of the arm body 301, improve the stability and load-bearing capacity of the structure, and at the same time, the bending direction of the arm body 301 can be determined in advance to prevent the arm body 301 from buckling and deforming when subjected to external force.

[0035] like Figure 5 As shown, the crane 4 includes a crane body 401. A crane motor 402 is mounted on one side of the crane body 401, driving the sling up and down. A hook 403, fixedly connected to the end of the sling, is mounted below the crane body 401. Travel wheels 404, symmetrically mounted on the upper end of the crane body 401 and cooperating with the lever arm 3, are controlled by a controller 405. By activating the crane motor 402, the hook 403 moves up and down, facilitating material loading and unloading. The controller 405 controls the travel distance and direction of the travel wheels 404, enabling material transportation.

[0036] like Figure 6 As shown, the injection molding machine 5 includes a workbench 501, a body 502 is mounted on the upper end of the workbench 501, and a mold 503 is mounted between the body 502. A control cabinet 504 electrically connected to the body 502 is mounted on one side of the workbench 501.

[0037] like Figure 7-10 As shown, an injection port 505 is provided at the center of the upper top of the mold 503. The upper end of the injection port 505 is in an inverted cone shape, which is used to speed up the injection speed and thus improve efficiency. An injection nozzle 506 that matches the injection port 505 is provided at the center of the bottom of the body 502. The lower end opening of the injection nozzle 506 is larger than the upper end opening. This design solves the problem that the silicone rubber after cooling is difficult to remove due to the same upper and lower opening size of the traditional injection nozzle and requires the use of matching tools. The design of the injection nozzle 506 in this application, which is narrow at the top and wide at the bottom, makes the weight of the cooled silicone rubber at the lower end opening greater than the weight at the upper end opening. Under the action of its own gravity, the silicone rubber at the injection nozzle 506 can be easily cleaned without the use of tools.

[0038] The action process of the present invention is as follows:

[0039] First, according to the needs, a suitable mold 503 is selected. When loading or replacing the mold, the crane 4 is used to move it to the appropriate position, and the hook 403 lifts it. Then, the walking wheel 404 moves along the lifting arm 3, and the reduction motor 105 drives the transmission gear 104 to rotate on the outer ring gear 107 to adjust the angle of the mold 503 to facilitate the operator to replace the mold. Then, the mold is installed on the main body 502 of the injection molding machine. The crane 4 and the 360° rotating platform 1 continue to cooperate with each other to transport the raw materials to the injection molding machine body 5. Finally, the control cabinet 405 is started and the program controls the heating of the silicone rubber into a liquid state. Then, it is pressurized by the pressure pump and injected into the mold 503 through the nozzle. Then, the silicone rubber is cooled to solidify and form. In the above process, operations such as changing the mold and transporting and loading and unloading can be carried out by the crane in conjunction with the 360° rotating platform 1 around the injection molding machine body 5 to perform a small 360° operation. This not only saves space and labor, but also improves efficiency and reduces processing costs.

[0040] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
