[0011] Figure 2 This is a split diagram of the present invention. Detailed Implementation

[0012] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0013] The specific technical solution of this utility model is as follows: like Figure 1 and Figure 2 As shown, a molding die for irregularly shaped automotive parts includes a base plate 1, a pressure plate 2, and a core 3. A lower template 5 is detachably mounted on the base plate 1. A core groove 31 is formed on the top surface of the lower template 5. A portion of the core 3 is embedded in the core groove 31. An upper template 5 is detachably mounted on the bottom surface of the pressure plate 2. The upper template 5 is provided with a corresponding cavity through groove 51. An injection hole 6 communicating with the cavity through groove 51 is provided on the upper part of the pressure plate 2. The core 3 and the cavity through groove 51 are molded together to form a molding space for irregularly shaped automotive parts.

[0014] At least two positioning posts 11 are provided on the top surface of the base plate 1, and two corresponding positioning holes 41 are provided on the bottom surface of the lower template 4. The positioning posts 11 are inserted into the corresponding positioning holes 41. Specifically, the two positioning posts 11 and the two positioning holes 41 cooperate with each other to facilitate the detachable connection between the base plate 1 and the lower template 5.

[0015] The bottom surface of the pressure plate 2 is provided with a positioning protrusion 21, and the positioning protrusion 21 is provided with a first magnet 22. The top surface of the upper template 5 is provided with a corresponding positioning groove 52, and the bottom surface of the positioning groove 52 is provided with a second magnet 53. The positioning protrusion 21 is embedded in the positioning groove 52, and the magnetic poles of the first magnet 22 and the second magnet 53 are opposite. Specifically, the first magnet 22 of the positioning protrusion 21 and the second magnet 53 of the positioning groove 52 cooperate with each other to facilitate the detachable connection between the pressure plate 2 and the upper template 5.

[0016] The base plate 1 is provided with a support frame 8, and the support frame 8 is provided with a lifting cylinder 9. The output end of the lifting cylinder 9 is fixedly connected to the pressure plate 2. Specifically, the lifting cylinder 9 drives the pressure plate 2 to move up and down.

[0017] A set of guide posts 7 are provided on both sides of the base plate 1. The pressure plate 2 is provided with corresponding guide holes 71. The guide posts 7 are inserted into the guide holes 71. The top of the guide holes 71 is provided with a limiting head 72. Specifically, the stability of the lifting and moving of the pressure plate 1 is improved by the cooperation of the guide posts 7 and the guide holes 71.

[0018] In use, the corresponding upper template 5, lower template 4 and core 3 can be selected according to the irregular parts to be processed. After the selected lower template 4 is placed on the base plate 1, the two positioning holes 41 of the lower template 4 are inserted into the positioning posts 11 on the base plate 1 to complete the installation of the upper and lower templates 4 on the base plate 1. Then the lower part of the core 3 is embedded in the core groove 31 of the lower template 4. After that, the positioning protrusion 21 on the bottom surface of the pressure plate 2 is inserted into the positioning groove 52 of the upper template 5. The first magnet 22 on the positioning protrusion 21 and the second magnet 53 in the positioning groove 52 are magnetically attracted to each other, so that the upper template 5 is installed on the bottom surface of the pressure plate 2. When processing and producing irregularly shaped automotive parts, the lifting cylinder 9 is activated, which causes the pressure plate 2 to move along the guide post 7 towards the base plate 1. This allows the cavity through groove 51 of the upper mold plate 5 to move to the position of the core 3 on the lower mold plate 4. The cavity through groove 51 and the core 3 close to form the required molding space. At this time, the material can enter from the injection port 6, and the irregularly shaped automotive parts can be formed in the molding space, thus completing the processing and production of irregularly shaped automotive parts.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
