[0022] like Figure 1 As shown, the technical scheme adopted by the utility model is as follows: the demoulding device for mold processing proposed by this party includes a base 1, a hydraulic cylinder 3, an upper die 4, a lower die seat 5 and a demoulding assembly 6, the upper end of the base 1 is provided with a support frame 2, the hydraulic cylinder 3 is arranged on the top of the support frame 2, and a lifting plate 7 is slidably provided at the upper end of the top of the support frame 2, the output shaft of the hydraulic cylinder 3 is connected to the upper end of the lifting plate 7, and buffer columns 8 are arranged around the lower end of the lifting plate 7. The upper die 4 is installed with the lifting plate 7 through the buffer columns 8, and a mounting platform 9 is provided at the lower end of the support frame 2. The lower die seat 5 is installed on the mounting platform 9 and is located below the upper die 4.

A mold cavity 10 is provided in the lower die seat 5, and the demoulding assembly 6 is arranged on the base 1 and the upper end extends into the mold cavity 10.

[0023] like Figure 1 and Figure 2As shown, the demoulding assembly 6 includes a guide slide 11 and a support positioning tube 13, the guide slide 11 is slidably arranged at the lower end of the inner part of the support frame 2, and the lower end of the lifting plate 7 is symmetrically provided with a pull rope 17, and the lower end of the pull rope 17 is connected to the upper end of the guide slide 11, and the lower ends of the two sides of the support frame 2 are connected with a telescopic spring 18 through the support plate, and the upper end of the telescopic spring 18 is connected to the lifting plate 7, and the support positioning tube 13 is symmetrically arranged on both sides of the upper end of the guide slide 11, and the bottom of the lower mold base 5 is provided with guide grooves. The upper end of the positioning tube 13 extends through the guide groove into the mold cavity 10, and a supporting plate 12 is provided on the upper end of the supporting positioning tube 13.
