The bottom mold clamping base includes a fixing seat 10 and an adsorption seat 12. A clamping seat 7 is provided on the fixing seat 10 near the connecting plate 11. The clamping seat 7 has multiple sets of fixing pins and bolts on its inner side, which are detachably connected to the mounting box 1 and the connecting plate 11. The adsorption seat 12 is located above the fixed seat 10. The lower end of the adsorption seat 12 is provided with a mounting seat 13. The adsorption seat 12 is detachably connected to the mounting seat 13 by bolts. The mounting seat 13 is fixedly connected to the fixed seat 10 by a connecting rod. The lower end of the mounting seat 13 is fixed with a pipeline interface B14. The pipeline interface B14 is located below the adsorption seat 12 and is connected to the pipeline interface A5 through a flexible hose for adsorbing and clamping the bottom mold, facilitating the processing of the workpiece. An installation slide rail can be added to the mounting box 1 near the clamping seat 7 to facilitate the installation and fixation of multiple bottom mold clamping seats.
[0017] The mounting box 1 has an internal cavity, and a control valve is fixed inside the cavity. The control valve has pipes at both ends connected to pipe interfaces A5 and B14, respectively, for controlling the use of compressed gas. A gauge 6 is fixed to the upper end of the gas storage chamber 4 for detecting the internal pressure of the gas storage chamber 4. The bottom mold clamping base also includes a leveling seat 9, which is located at the upper end of the mounting base 13 and is detachably connected to the mounting base 13 by bolts. There are two adsorption seats 12, symmetrically arranged on both sides of the leveling seat 9, which are used to adjust the overall balance when the bottom mold is placed. A lifting rod 8 is fixed to the lower end of the mounting base 13. The mounting base 10 has a cylindrical cavity inside for sliding connection with the lifting rod 8. One side of the mounting base 10 has a pipe connected to the control valve, and one end of the control valve is connected to the cylindrical cavity for controlling the height of the mounting base 13 in conjunction with the lifting rod 8. There are two sets of lifting rods 8, symmetrically arranged with the axis of the mounting base 13 as the reference. Guide rods 15 are provided on both sides of the lifting rods 8.

The height of the sealing strip is higher than the height of the leveling seat 9. The materials of the leveling seat 9 and the adsorption seat 12 can be replaced with nylon, bakelite, or other materials according to usage requirements. When leveling is required, the installation position of the adsorption seat 12 can be adjusted by sliding bolts to make its upper surface parallel to the leveling seat.
[0019] When in use, a workpiece with a regular shape can be placed directly on the upper end of the leveling seat 9 and the adsorption seat 12. At the same time, the height of the lifting rod 8 can be adjusted through the control terminal to keep it on a relatively flat plane. Then, the control valve is activated to change the direction of compressed air flow, so that the adsorption seat 12 adsorbs and fixes the workpiece. After fixing, processing can be carried out.
