As shown in fig. 1-4, the plastic-absorbing part jacking mechanism of the plastic-absorbing forming machine of the present invention comprises a base 1. The base 1 is internally provided with an installation cavity, and the top of the base 1 is provided with an opening 11 communicated with the installation cavity. The mounting chamber is used for mounting components such as a mold base, a lifting mechanism, a vacuum pumping device and the like. The periphery of the opening 11 is provided with a flange 2 facing the outside of the base 1. The flanging 2 is perpendicular to the side wall of the base 1. The upper surface of the flanging 2 is provided with a fixed frame 3. The opening 11 is placed in the fixed frame 3. The fixed frame 3 is a rectangular frame structure surrounded by frame edges and made of heat-resistant rubber materials. A movable frame 4 is mounted below the flange 2, and the shape of the movable frame 4 is substantially the same as that of the fixed frame 3, and the movable frame 4 is a rectangular frame mechanism. The base 1 is placed in a moving frame 4. The movable frame 4 is connected with the base 1 in an up-and-down sliding manner, specifically, sliding rails are installed on the side walls of the base 1 and are arranged along the vertical direction. The moving frame 4 is slidably mounted on a slide rail. The base 1 is provided with a driving mechanism for driving the movable frame 4 to slide up and down. Each frame edge of the fixed frame 3 is distributed with a through hole 31. The central axis of the through hole 31 extends in the vertical direction. The moving frame 4 is provided with a jack 41 corresponding to each through hole 31. The jack 41 is vertically fixed to the moving frame 4. The upper end of the mandril 41 movably penetrates through the flanging 2 and is in inserted fit with the through hole 31. As shown in fig. 4, the flange 2 is likewise provided with a through-hole corresponding to the through-hole 31, so that the plunger 41 projects from the through-hole into the through-hole 31.

The driving mechanisms are installed at opposite sides below the moving frame 4 and include a guide bracket 5, a moving rod 51, an upper wedge 53 and a lower wedge 52. The guide bracket 5 is provided with a plurality of guide brackets which are fixed on the outer side wall of the base 1. The specific structure of the guide bracket 5 is shown in fig. 7. The moving bar 51 has an elongated structure, is arranged in the front-rear direction, and is slidably mounted on the guide frame 5 in the front-rear direction. The upper wedge blocks 53 are fixed to the bottom of the moving frame 4. The lower wedge 52 is fixed to the moving rod 51. The upper wedge block 53 and the lower wedge block 51 correspond to each other up and down, and the wedge surface of the upper wedge block 53 is connected with the wedge surface of the lower wedge block 52 in a sliding fit manner. The movable rods 51 on two sides move synchronously towards the front side, and then the lower wedge block 51 is driven to move towards the front side, and the upper wedge block 53 and the movable frame 4 are driven to move upwards integrally through the cooperation of the upper wedge block 53 and the lower wedge block 51. The upper wedge 53 and the lower wedge 51 may be arranged in plurality according to actual needs. The moving frame 4 can be moved downward by its own weight by synchronously moving the moving rods 51 of both sides toward the rear side. In order to enable the moving frame 4 to smoothly move downwards, a plurality of springs 54 are arranged between the flanging 2 and the moving frame 4, one end of each spring 54 is connected with the flanging 2, and the other end of each spring 54 is connected with the moving frame 4.
