[0025] Please see Figure 1-4 This utility model provides a technical solution: a resettable automotive parts mold structure, including a lower mold 1, an ejector mechanism 5, and a cooling mechanism 4. An upper mold 2 is placed on the top of the lower mold 1. A set of forming grooves 3 are provided on the top of the lower mold 1 and the bottom of the upper mold 2. The two sets of forming grooves 3 together form a forming cavity. The ejector mechanism 5 is set on the lower mold 1 and is used to assist in product unloading. A feed pipe 6 that communicates with the inside of the forming grooves 3 on the upper mold 2 is fixedly installed on the top of the upper mold 2. A set of handle grooves 7 are provided on both sides of the upper mold 2. A connecting line 8 is fixedly connected to the rear outer surface of the lower mold 1. At least two sets of limiting posts 9 are fixedly installed on the top of the lower mold 1. The bottom of the upper mold 2 has a number of limiting grooves equal to the number of limiting posts 9. Each set of limiting posts 9 is inserted into the corresponding limiting groove.

[0026] Cooling mechanism 4 is provided on lower mold 1 and upper mold 2. Cooling mechanism 4 includes spiral pipe 44, connecting pipe 45, sealing ring 46, docking groove 47 and connecting port 48. Both lower mold 1 and upper mold 2 have a set of spiral pipe 44 inside. The bottom of upper mold 2 is fixedly installed with connecting pipe 45 communicating with spiral pipe 44 on upper mold 2. Sealing ring 46 is fixedly installed at the bottom of connecting pipe 45. The top of lower mold 1 has docking groove 47. The top of lower mold 1 also has connecting port 48 communicating with spiral pipe 44 on lower mold 1. Connecting pipe 45 is inserted into docking groove 47.

[0027] The cooling mechanism 4 also includes an inlet pipe 41, an outlet pipe 42, and connectors 43. The inlet pipe 41, which communicates with the spiral pipe 44 on the upper mold 2, is fixedly installed on the front outer surface of the upper mold 2. The outlet pipe 42, which communicates with the spiral pipe 44 on the lower mold 1, is fixedly installed on the front outer surface of the lower mold 1. A set of connectors 43 is fixedly installed at one end of both the inlet pipe 41 and the outlet pipe 42. Through the cooling mechanism 4, the cooling water passes through the upper mold 2 and then enters the lower mold 1, making full contact with the forming grooves 3 on the lower mold 1 and the upper mold 2 to cool the product in all directions. This solves the problem that in some existing molds, the cooling structure is only located in one of the upper and lower molds and cannot cover all mold areas, resulting in insufficient cooling effect on the product. This improves the practicality of the structure.

[0028] The ejector mechanism 5 includes a servo motor 51, a threaded rod 52, a square cylinder 53, and an ejector plate 54. A groove is provided at the bottom of the lower mold 1, and a square groove is provided at the bottom inner side of the forming groove 3 on the lower mold 1. The servo motor 51 is fixedly installed at the top inner side of the groove, and the threaded rod 52 is rotatably installed at the bottom inner side of the square groove. The shaft of the servo motor 51 is connected to the threaded rod 52 via a transmission connection. A square cylinder 53, which fits against the inner wall of the square groove, is threaded onto the threaded rod 52. An ejector plate 54, which fits against the inner wall of the forming groove 3 on the lower mold 1, is fixedly installed at the top of the square cylinder 53. Through the ejector mechanism 5, after the product is formed in the forming groove 3, it can be ejected to assist in unloading and automatically reset. Compared to the existing manual operation, this saves time and effort, ensures the effectiveness of the structure, and is conducive to the promotion and use of the device.

[0029] Working principle: The water inlet pipe 41 and the water outlet pipe 42 are connected to the external water pipe through the connector 43. The molten raw material is introduced into the molding cavity through the feed pipe 6. The water flows through the water inlet pipe 41 into the spiral pipe 44 in the upper mold 2, and then through the connecting pipe 45 into the connecting port 48. After flowing through the spiral pipe 44 on the lower mold 1, it flows out from the water outlet pipe 42. After cooling the product, the upper mold 2 is removed. The servo motor 51 is started, which drives the threaded rod 52 to rotate, which drives the square cylinder 53 and the top plate 54 to move upward, ejecting the product and resetting it after the product is removed.
