[0035] Specifically, the flange 11 is embedded in the mounting groove 14 and fits against the inner wall of the mounting groove 14, a rubber pad is bonded to the end of the support column 12, the lower mold 13 is connected to the flange 11 by bolts, and the bolts are fixed by waist-shaped holes; the lower surface of the hanger 29 is also provided with a flange 11 and a support column 12, the upper surface of the upper mold 211 is also provided with a mounting groove 14, the lower surface of the upper mold 211 is provided with a protrusion adapted to the sealing groove 15, and the lower surface of the upper mold 211 is also provided with a shell groove 16.

[0036] In this embodiment, the lower mold 13 is connected to the top of the base 1 through the flange 11, and the bolts are connected through the waist-shaped holes on the side of the lower mold 13 to provide the lower mold 13 with a small space for up and down movement. The lower inner wall of the lower mold 13 contacts the support column 12 through the rubber pad. The elasticity of the rubber pad provides a buffer for the small movement of the lower mold 13, thereby reducing the impact generated during the clamping process of the upper and lower molds. During the process of the lower mold 13 and the upper mold 211 being fitted together, the protrusion on the lower surface of the upper mold 211 is embedded in the sealing groove 15, increasing the contact area between the lower mold 13 and the upper mold 211, thereby improving the sealing. The lower mold 13 is engaged with the shell groove 16 on the upper mold 211, and the shell core on the upper mold 211 is embedded in the inner side of the engaged shell groove 16, and cooperates with the inner wall of the shell groove 16 to enclose and form an inner cavity that conforms to the shell of the pneumatic component for injection molding.

The positioning bar 2202 is provided to position and support the support frame 2, thereby improving the stability of the support frame 2 and preventing the support frame 2 from deviating sideways as the threaded rod 21 rotates. The drive motor 23 drives the threaded rod 21 to rotate during operation, and pushes the support frame 2 to slide back and forth on the base 22 through the action of the thread, thereby assisting in positioning the upper mold 211. When the upper mold 211 is misaligned with the lower mold 13, it is convenient to disassemble and clean the upper mold 211 and the lower mold 13.

[0039] Specifically, the top of the support frame 2 is slidably connected with a push rod 201, a spring is arranged between the push rod 201 and the support frame 2, the connecting sleeve 24 is nested on the top of the support frame 2 and fits tightly with the push rod 201, a waist-shaped hole is arranged on the side of the connecting sleeve 24 and bolts are connected through the waist-shaped hole, and the connecting sleeve 24 is connected to the support frame 2 through the above-mentioned bolts.

The front positioning hook 32 is provided to fix the front edges of the first pad 3 and the second pad 4. Since the second pad 4 is narrower in width and the contact surface with the desktop 5 is smaller than that of the first pad 3, a rear positioning hook 33 is provided behind the second pad 4 to form a second positioning structure behind the second pad 4, thereby improving the positioning stability of the second pad 4 on the desktop 5.

[0045] When in use, place the first pad 3 in the middle of the desktop 5, and make the front positioning hook 32 on the first pad 3 fit with the front edge of the desktop 5, turn the adjusting bolt 34, make the wear-resistant pad 36 on the pressing plate 35 fit with the lower surface of the desktop 5, complete the positioning of the first pad 3, place the lower mold 13 above the base 1, make the flange 11 embedded in the mounting groove 14, bolt it in, place the two second pads 4 on both sides of the first pad 3, respectively, sleeve the connecting sleeve 24 on the upper end of the support frame 2, make the top rod 201 fit with the inner wall of the connecting sleeve 24, bolt it in the side of the connecting sleeve 24, complete the support plate 25.
