[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1:

[0023] This application provides a sewing machine mold, including an upper template 1. Below the upper template 1, from top to bottom, are arranged an upper module 2, a lower module 3, a positioning block 4, a lower template 5, and a base 6. An injection port 8 is provided in the inner cavity of the upper module 2. The lower module 3 is fixedly installed at the bottom of the upper module 2. Upper mold inserts 11 are symmetrically arranged in the inner cavity of the upper module 2. An upper mold core 12 is provided in the inner cavity of the lower module 3. The upper module 2, the lower module 3, the upper mold inserts 11, and the upper mold core 12 form a mold cavity. An injection port 8 is opened in the inner cavity of the upper template 1, and the injection port 8 is through-connected to the two sets of upper mold inserts 11.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during the use of the device, the material is input through the injection port 8 into the upper module 2, lower module 3, upper mold insert 11, and upper mold core 12 to form a mold cavity. After injection molding inside the mold cavity formed by the upper module 2, lower module 3, upper mold insert 11, and upper mold core 12, it becomes a sewing machine. After injection molding is completed, when the upper module 2 and lower module 3 separate, the sewing machine can be ejected from the mold cavity by the ejector pin 13 on the surface of the top plate 7 through the buffer mechanism 9. This allows for the rapid completion of the injection molding process of the sewing machine. This utility model uses an injection mold to integrally mold the sewing machine, eliminating the need for manual assembly, reducing manpower consumption, and lowering the labor intensity of workers. It also eliminates the need for personnel to use precision machining, precision casting, welding, and other technologies to process the sewing machine, while greatly improving production efficiency and meeting the needs of modern high-speed production. Furthermore, the integrally molded sewing machine has better quality and is less prone to damage, thus improving the service life of the sewing machine to a certain extent.

[0025] Furthermore, a top plate 7 is provided in the inner cavity of the lower mold plate 5, and a buffer mechanism 9 is symmetrically provided on the top of the top plate 7. The buffer mechanism 9 includes a positioning rod 901, a spring 902 and a slider 903. The positioning rod 901 is symmetrically provided on the surface of the top plate 7, the spring 902 is installed on the surface of the positioning rod 901, and the slider 903 is slidably installed above the spring 902. A lower mold core 10 is installed in the inner cavity of the positioning block 4, and the slider 903 is provided below the lower mold core 10. Ejector pins 13 are provided at equal intervals on the surface of the top plate 7, and the ejector pins 13 are correspondingly provided with the mold cavity.

[0026] Specifically, such as Figure 1 , Figure 2 As shown, when the device completes the injection molding of the sewing machine, and the upper module 2 and the lower module 3 are separated, the lower mold core 10 will be compressed by the spring 902 above the positioning rod 901 on the surface, which will drive the slider 903 and the lower mold core 10 to move upward. At the same time, since the ejector pin 13 corresponds to the mold cavity, the sewing machine in the mold cavity can be quickly pushed up by the ejector pin 13, thereby further improving the working efficiency of the device in processing the sewing machine.

[0027] Working principle: The material is fed into the upper module 2, lower module 3, upper mold insert 11, and upper mold core 12 through the injection port 8 to form a mold cavity. After injection molding inside the mold cavity formed by the upper module 2, lower module 3, upper mold insert 11, and upper mold core 12, it becomes a sewing machine. After injection molding is completed, when the upper module 2 and lower module 3 separate, the sewing machine can be ejected from the mold cavity by the ejector pin 13 on the surface of the top plate 7 through the buffer mechanism 9. This allows for the rapid completion of the injection molding process of the sewing machine. This utility model uses an injection mold to integrally mold the sewing machine, eliminating the need for manual assembly, reducing manpower consumption, lowering the labor intensity of workers, and eliminating the need for personnel to use precision machining, precision casting, welding, and other technologies for processing, while also greatly improving production efficiency.

[0028] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
