[0031] like Figure 1 As shown, an injection molding machine capable of rotating 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, a support column 2 is installed above the 360° rotating platform 1, and 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 the 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 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, a rotating track 102 is fixedly installed on the fixed base 101, and a rotating body 103 is rotatably installed at the inner center position of the rotating track 102. A transmission gear 104 is frictionally contacted on 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 gear transmission is adopted in this application, and its transmission efficiency is very high, which can usually reach more than 98%. Therefore, there is only a small energy loss during the energy transfer process, 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 installed 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 in an L-shaped structure, and the reduction motor 105 is installed on its upper end surface distributed laterally, and is protected by the vertically distributed structure to prevent the reduction motor 105 from being damaged after the crane 4 over-travels, and also to achieve a 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, which meets the large-space operation of the injection molding machine loading and unloading process, improves efficiency, and reduces 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 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 for driving the sling to move up and down is installed on one side of the crane body 401, and a hook 403 fixedly connected to the end of the sling is installed below the crane body 401. A walking wheel 404 matching the lever 3 is symmetrically installed on the upper end of the crane body 401, and the walking wheel 404 is controlled by a controller 405. By starting the crane motor 402, the hook 403 moves up and down, which facilitates loading and unloading, and the running distance and direction of the walking wheel 404 are controlled by the controller 405 to realize the transportation of materials.

[0036] like Figure 6 As shown, the injection machine body 5 comprises 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 the efficiency. An injection nozzle 506 matching the injection port 505 is provided at the center of the bottom of the body 502. The lower opening size of the injection nozzle 506 is larger than the upper opening size. This design solves the problem that the silicone rubber after cooling is difficult to remove due to the same upper and lower opening sizes of the traditional injection nozzle and requires the use of matching tools. The design of the injection nozzle 506 in the present application, which is narrow at the top and wide at the bottom, makes the weight of the silicone rubber at the lower opening after cooling greater than the weight at the upper opening. Under the action of its own gravity, the silicone rubber at the injection nozzle 506 can be easily cleaned without the help of tools.

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

[0039] First, according to the needs, select a suitable mold 503. When the mold is installed or replaced, the crane 4 is used to move it to a suitable position, and the hook 403 lifts it. Then the walking wheel 404 moves along the lifting arm 3, and the transmission gear 104 is driven by the reduction motor 105 to rotate on the outer gear ring 107, and the angle of the mold 503 is adjusted to facilitate the operator to replace the mold; then, the mold is installed on the main body 502 of the injection molding machine, and 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, and then the pressure pump is pressurized and injected into the mold 503 through the nozzle, and then the silicone rubber is cooled to solidify and form. In the above process, the operations of replacing the mold and transporting and loading and unloading can be carried out by the crane in cooperation with the 360° rotating platform 1 around the injection molding machine body 5 in a small range of 360°, which not only saves space, but also saves labor, improves efficiency, and reduces processing costs.

[0040] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
