[0030] As shown in the figure, the three-color mold forming device 100 comprises a moving plate 10, a bearing plate 20, a rotating device 30 and a driving device 40; the moving plate 10 is provided with a shovel base 11 on the side facing the bearing plate 20, and is provided with an upper mold meat 12 of a first injection mold, an upper mold meat 13 of a second injection mold and an upper mold meat 14 of a third injection mold around the shovel base 11, and is provided with an injection tube 15 at the position corresponding to the upper mold meat 11, 12 and 13 on the top surface of the moving plate 10, which communicates with the upper mold meat 11, 12 and 13 respectively, and is used for injection molding of the to-be-injection-molded mold 50; the bearing plate 20 is provided with a first installation groove 21, and is provided with a first injection mold meat 24, a second injection mold meat 24 and a third injection mold meat 24 around the first installation groove 21, and is provided with a first installation hole 25 relative to the shovel base 11 in the first installation groove 21; the rotating device 30 comprises a rotating platform 31 and at least one rotating component, the rotating platform 31 is arranged in the first installation groove 21, the rotating component is arranged on the rotating platform 31 relative to the first injection mold and is movably connected with the shovel base 11, and is used for installing the to-be-injection-molded mold 50; the driving device 40 comprises a connecting rod 41, the connecting rod 41 is connected with the rotating platform 31 through the first installation hole 25, the connecting rod 41 can be lifted under the driving of an external power device to complete the mold closing and mold opening of the moving plate 10 and the bearing plate 20, at the same time, the connecting rod 41 can also be rotated under the driving of the external power device to make the rotating component rotate between the first injection mold, the second injection mold and the third injection mold to complete the injection molding of the to-be-injection-molded mold 50.

[0031] Among them, the to-be-injection-molded mold 50 can be a toothbrush handle cylinder, when the toothbrush handle cylinder is injection molded, it is generally divided into three processes, first, the toothbrush handle cylinder is injection molded to form an LED lamp cover on the toothbrush handle cylinder, then the LED lamp cover and the handle cylinder are injection molded again to encapsulate the LED lamp cover and the handle cylinder, and finally the handle cylinder is injection molded with soft glue to complete the entire forming process. The first injection mold, the second injection mold and the third injection mold in the present application correspond to the above three processes respectively, it is worth mentioning that although the toothbrush handle cylinder is taken as an example, the present application can also be applied to products similar to the toothbrush handle cylinder which also need to be injection molded in three steps, the toothbrush handle cylinder is taken as an example for illustration.

[0032] The movable plate 10 is sized to match the support plate 20. A base 11 is provided on the movable plate 10, for example, at its center. Around this base 11 are spaced upper mold plates 12, 13, and 14, representing the upper molds of a first, second, and third injection mold. Correspondingly, the support plate 20 has lower mold plates 22, 23, and 24, representing the lower molds of a first, second, and third injection mold. The spacing between the first, second, and third injection molds can be 120°, meaning they are evenly distributed around the base 11. When the movable plate 10 and support plate 20 are closed, the upper mold plates 12 and 22 of the first injection mold combine to form a cavity. The injection tube 15, located above this cavity, can inject the mold 50 to be injection molded within the cavity. Figure 5 and Figure 6 As shown, the upper mold core 12 and lower mold core 22 of the first injection mold are specifically provided with corresponding grooves on the moving plate 10 and the supporting plate 20 respectively. The shape of the groove matches the mold 50 to be injected. When the upper mold core and the lower mold core are combined together, a space is formed, which is the cavity.

[0033] A first mounting groove 21 can be provided at the center of the bearing plate 20. A mounting hole is provided in the first mounting groove 21 at a position corresponding to the shovel base 11. The rotating platform 31 is provided in the first mounting groove 21, and a structure connected to the connecting rod 41 is provided at the bottom of the rotating platform 31. The connecting rod 41 can drive the rotating platform 31 to rise under the drive of an external power device. The rotating component is connected to the shovel base 11 of the moving plate 10, so it can drive the moving plate 10 to rise synchronously. The external power device is provided by other equipment. For example, the drive rod 42 of the drive device 40 is fixed to other power devices, and the drive rod 42 is driven to rotate or rise by the power device, thereby driving the connecting rod 41 to rotate or rise.

[0034] like Figure 1 As shown, Figure 1 This describes the state when the movable plate 10 and the support plate 20 are closed. When the movable plate 10 and the support plate 20 are closed, the movable plate 10 and the support plate 20 are attached together, and the injection tube 15 injects the corresponding injection mold 50 into the mold to be injected. Figure 2 As shown, it can be done through Figure 2To understand the structure when the moving plate 10 and the bearing plate 20 are opened, the connecting rod 41 in the driving device 40 can be lifted by the driving of the external power device to drive the rotating platform 31 connected thereto to rise, and then drive the whole rotating device 30 to rise, and the rotating assembly is movably connected with the shovel base 11, and then can drive the moving plate 10 to rise, so as to complete the opening of the mold. After that, the connecting rod 41 is driven by the external power device to descend slightly, so that the rotating assembly is separated from the shovel base 11. When the rotating assembly is separated from the shovel base 11, the rotating device 30 is separated from the moving plate 10, and the connecting rod 41 can be rotated by the driving of the external power device, and then drive the rotating platform 31 to rotate. Taking clockwise rotation as an example, the rotating assembly is rotated from the position of the first injection mold to the position of the second injection mold, and then the connecting rod 41 is continuously lifted by the driving of the external power device until the rotating assembly is connected with the shovel base 11 again. Then the connecting rod 41 is driven by the external power device to descend until the moving plate 10 and the bearing plate 20 are closed again, that is, in the state shown in the figure, the injection tube 15 above the second injection mold performs injection molding on the to-be-injection-molded mold 50. When the to-be-injection-molded mold 50 completes the injection molding in the second injection mold, the above opening process is repeated, the rotating assembly is rotated to the third injection mold, and then the above closing process is repeatedly performed, so that the to-be-injection-molded mold 50 is located in the third injection mold. When the to-be-injection-molded mold 50 completes all injection molding, the above opening and closing processes are repeated to return to the first injection mold, and then the to-be-injection-molded mold 50 is taken out by the rear equipment and reinstalled. Figure 1

When the first rotating assembly 32 rotates to the second injection mold, the third rotating assembly 34 rotates to the first injection mold to start injection, and the second rotating assembly 33 rotates to the third injection mold to wait to rotate to the first injection mold to start injection. In addition, the injection tube 15 can be connected with the related injection equipment to control the injection of the injection tube 15 by the injection equipment.
