DETAILED DESCRIPTION

[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] The specific problem addressed by this specific embodiment is to solve the problem that when the two-color injection molding device rotates, there is a lack of structure to firmly clamp the first color product. The centrifugal force generated by the rotation will cause the first color product to loosen and deviate. Therefore, when the second color is applied to the first color product, it will also deviate, affecting the coloring quality of the product. After the first color product is injected on the surface of the injection mold 3, the driving motor 41 drives the positive and negative screws 42 fixed at its output end to rotate. The clamping structure 44 fixed on the surface of the positive and negative screws 42 by the moving block 43 is synchronously in opposite directions and protrudes from the inside of the sliding port on the side of the injection mold 3, thereby fixing the first color product and preventing it from deviating during rotation.

[0025] The clamping assembly 4 includes a driving motor 41 fixedly connected to the inside of the two-color injection molding equipment 2, and the output end of the driving motor 41 is fixedly connected to a forward and reverse screw rod 42, and the two ends of the forward and reverse screw rod 42 are axially symmetrically threadedly connected to a moving block 43, and the top surface of the moving block 43 is provided with a clamping structure 44. In this specific embodiment, the clamping structure 44 includes a moving rod 441 fixedly connected to the top surface of the moving block 43, and the side of the moving rod 441 is fixedly connected with a plurality of sleeves 442 in sequence from top to bottom. A slidable slide rod 443 is provided inside the sleeve 442, and the slide rod 443 is fixedly connected to the side of the sleeve 442 by a spring 444, and a clamping plate 445 is fixed to the side of the slide rod 443. After the injection molding of the first color product on the surface of the injection mold 3 is completed, the driving motor 41 drives the positive and negative screws 42 fixed at the output end to rotate, and the moving blocks 43 with axially symmetrical threaded connections on the surfaces of the positive and negative screws 42 move away from each other, which drives the moving rod 441 fixed on the top surface to move synchronously. After the sleeve 442 set on the side of the moving rod 441 protrudes from the side sliding opening of the injection mold 3, the sleeve 442 drives the clamping plate 445 fixed on the side to move through the slidable slide rod 443 set by the fixing spring 444, and the clamping plate 445 is squeezed and fixed inside the first color product, so that the first color product can be squeezed and fixed firmly, which prevents the first color product from loosening and deviating during rotation, thereby affecting the injection molding effect of the second color of the first color product.

[0026] In this specific embodiment, a cavity is provided inside the injection mold 3, and a semiconductor cooling sheet 7 for cooling is provided inside the cavity, a device box 8 is provided on the top surface of the rotating table 1, and a controller 9 for temperature control is sleeved inside the device box 8;
