A through-hole is opened on the top surface of the bottom demolding template 2, and an elastic element is slidably connected to the inner side of the through-hole. A lower silicone mold body 4 is fixedly connected to the top surface of the demolding reset plate 3. Through the action of the demolding assembly, after the model is injected, the lower silicone mold body 4 is pressed down, and the demolding boss 15 is used to quickly demold the model.

[0023] Furthermore, the mold closing guide assembly includes a guide sliding sleeve 5 and a guide sliding rod 6. The guide sliding sleeve 5 is fixedly connected to the inner side of the guide mounting groove 14, and the guide sliding rod 6 is slidably connected to the inner side of the guide sliding sleeve 5. The top surface of the guide sliding rod 6 is fixedly connected to an upper silicone support plate 7. Through the action of the mold closing guide assembly, the upper silicone mold body 10 and the lower silicone mold body 4 can be directly, quickly and accurately aligned and closed.

[0024] Furthermore, the top surface of the lower silicone mold 4 is provided with an injection groove 16 that penetrates the bottom, and the top surface of the upper silicone mold 10 is provided with an injection hole that penetrates the bottom. A demolding boss 15 is slidably connected to the inner side of the injection groove 16. A mold closing assembly is provided on the inner side of the injection groove 16 and the injection hole.

The upper fluororubber mold 17 is fixedly connected to the bottom inner side of the injection hole. The injection molding fluororubber mold 11 is fixedly connected to the inner side of the lower fluororubber mold 12 and the upper fluororubber mold 17.

[0026] Working principle: When this utility model is needed, a bottom demolding template 2, a demolding reset plate 3, a lower silicone mold body 4, and a guide sliding sleeve 5 are installed on the inner side of the top surface of the lower silicone support base plate 1. Simultaneously, a lower fluororubber mold 12 is installed on the inner side of the injection groove 16 inside the lower silicone mold body 4, and an injection molding fluororubber mold 11 is installed on the inner side of the lower fluororubber mold 12. The guide sliding rod 6 on the bottom surface of the upper silicone support top plate 7 guides and cooperates with the guide sliding sleeve 5 to complete the mold closing between the lower silicone mold body 4 and the upper silicone mold body 10. During mold closing, the injection hole opened on the top surface of the upper silicone mold body 10... The inner side is equipped with a fluororubber pipe 8 and an upper fluororubber mold 17. After the mold is closed, the fluororubber is injected into the inner side of the injection molding fluororubber mold 11 from the inner side of the top fluororubber pipe 8. At the same time, the heat inside the injection molding fluororubber mold 11 is quickly dissipated through the interaction of the mold closing heat dissipation hole and the heat dissipation hole 9, which accelerates the cooling and molding process. When demolding is required, the upper silicone support plate 7 and the upper silicone mold body 10 are removed. Then, the lower silicone mold body 4 is pressed down, causing the lower silicone mold body 4 and the demolding reset plate 3 to move downward. At the same time, the mold is ejected by the demolding boss 15, and the mold is reset by the elastic element at the bottom of the demolding reset plate 3.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
