[0028] Embodiment 1

[0029] Refer to Figure 2 and Figures 4 to 7, which is the first embodiment of the present utility model. This embodiment provides a demolding cylinder with adjustable pressure. The demolding cylinder with adjustable pressure includes a rotating assembly 200, which comprises a support tube 201a, a positioning sleeve 201b, a rotating rod 201c, a connecting rod 201d, a compression spring 201e, a positioning block 201f, a limiting block 201g, an inclined surface card slot 201h, a support rod 201i, a gear 201j, a rotating block 201k, a fixed block 201l, a helical gear 201m, a rotating column 201n, a movable block 201o, a control spring 201p, a fixed rod 201q and a spherical valve 201r. The positioning sleeve 201b is fixed inside the support tube 201a. The rotating rod 201c is rotatably connected inside the positioning sleeve 201b. The connecting rod 201d is fixed to one end of the rotating rod 201c. The compression spring 201e is fixed to one side of the positioning sleeve 201b. The positioning block 201f is fixed to one side of the positioning sleeve 201b. The limiting block 201g is fixed to one side of the positioning block 201f. A sliding groove V is formed on the surface of the rotating rod 201c. The limiting block 201g is arranged inside the sliding groove V. The inclined surface card slot 201h is fixed inside the rotating rod 201c. The support rod 201i is arranged on one side of the rotating rod 201c. The gear 201j is fixed to the surface of the support rod 201i. The gear 201j can meshingly rotate with the inclined surface card slot 201h. The rotating block 201k is fixed to one end of the support rod 201i. The fixed block 201l is fixed inside the support tube 201a. The helical gear 201m is arranged inside the rotating block 201k. The rotating column 201n is located inside the helical gear 201m. The movable block 201o is rotatably connected inside the rotating column 201n. The movable block 201o meshingly rotates with the helical gear 201m. One end of the control spring 201p is fixed inside the rotating column 201n. The other end of the control spring 201p is fixed to one side of the movable block 201o. The fixed rod 201q is fixed to one side of the rotating column 201n. The spherical valve 201r is fixed to one side of the fixed rod 201q.

[0030] The support tube 201a is used to ensure the normal operation of the entire rotating assembly 200, so as to ensure that the rotating assembly 200 can adjust the air pressure in the cylinder. The positioning sleeve 201b is used to support the position of the rotating rod 201c, ensuring that the rotating rod 201c will not deviate when it rotates. The connecting rod 201d is used to drive the rotating rod 201c to rotate. The compression spring 201e is used to control the position of the rotating assembly 200, so as to ensure the normal operation of the rotating assembly 200. The positioning block 201f is used to fix the position of the limiting block 201g, so as to ensure that when the rotating rod 201c is driven by the connecting rod 201d to rotate, through the mutual cooperation of the sliding groove V and the limiting block 201g, the rotating rod 201c can rotate in one direction. When the rotating rod 201c rotates, it can simultaneously drive the gear 201j to rotate through the inclined plane card slot 201h, so that the gear 201j can drive the support rod 201i to rotate.

The fixing block 201l is used to support the position of the rotating block 201k, ensuring that the rotating block 201k will not shake when it rotates. Because the helical gear 201m meshes with the movable block 201o, when the rotating block 201k rotates, it can drive the movable block 201o to rotate through the helical gear 201m, so as to ensure that the movable block 201o can drive the rotating column 201n to rotate. The control spring 201p is used to ensure that the movable block 201o can mesh with the helical gear 201m. When the helical gear 201m rotates in the reverse direction, the helical gear 201m will squeeze the position of the movable block 201o, so that the helical gear 201m cannot mesh with the movable block 201o. When the helical gear 201m rotates forward, due to the push of the control spring 201p, it is ensured that the movable block 201o can mesh with the helical gear 201m, so as to ensure that the rotating column 201n can drive the fixed rod 201q to rotate only in one direction, so that the fixed rod 201q can drive the spherical valve 201r to rotate, so that the spherical valve 201r can control the air pressure in the demoulding cylinder, ensuring that the force during the demoulding process can act on the mold stably and precisely.

[0031] Embodiment 2

[0032] Referring to Figure 3 、 Figure 5 and Figure 6 , this is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0033] Specifically, it further includes a pushing assembly 300, which is arranged in the support tube 201a and includes a moving rod 301a and a pushing block 301b. The moving rod 301a slides in the support tube 201a. One end of the moving rod 301a is fixed to one side of the compression spring 201e, and the pushing block 301b is fixed to the other end of the moving rod 301a.

[0034] When the moving rod 301a moves, it can squeeze the compression spring 201e, thereby ensuring that the compression spring 201e can push the moving rod 301a to reset, so as to ensure that the pushing component 300 can cooperate with the rotating component 200. The pushing block 301b is used to push the moving rod 301a to move. After the pushing block 301b moves a certain distance, the pushing block 301b can contact the connecting rod 201d, and at the same time, the connecting rod 201d is also pushed to move, so that the connecting rod 201d can drive the rotating rod 201c to move, so as to ensure that the rotating component 200 can operate normally.

[0035] Specifically, a support block 301c is arranged on the surface of the moving rod 301a.

[0036] The support block 301c is used to support the position of the entire pushing component 300, so as to ensure that the pushing component 300 can operate normally.

[0037] Specifically, a positioning rod 301d is fixed on one side of the support block 301c.

[0038] The positioning rod 301d is used to ensure that the pushing component 300 can operate normally, so that the pushing component 300 can cooperate with the rotating component 200 for use.

[0039] Specifically, a limiting plate 301e is arranged on the surface of the positioning rod 301d, and the limiting plate 301e is rotatably connected to the surface of the positioning rod 301d.

[0040] The limiting plate 301e is used to limit the position of the moving rod 301a, so as to ensure that the moving rod 301a will not move under external force, so as to ensure that the rotating component 200 can operate normally.

[0041] Specifically, a compression spring 301f is fixed on one side of the limiting plate 301e.

[0042] The compression spring 301f is used to control the position of the limiting plate 301e. Therefore, the limiting plate 301e can limit the position of the moving rod 301a, so that the moving rod 301a will not move independently.

[0043] Embodiment 3

[0044] Refer to Figure 1 and Figure 2 , which is the third embodiment of the present utility model. This embodiment is based on the first two embodiments.

[0045] Specifically, it further includes a main body component 100, which is arranged on one side of the support block 301c and includes a cylinder 101 and a first piston surface 102. The cylinder 101 is fixed on one side of the support block 301c, and the first piston surface 102 is arranged in the cylinder 101.

[0046] The air cylinder 101 is used to convert pneumatic energy into mechanical energy for realizing the motion control, positioning, and force driving of mechanical devices. The first piston surface 102 is used to compress the air pressure inside the air cylinder 101 to meet different process requirements.

[0047] Specifically, a limiting rod 103 is provided on the surface of the first piston surface 102. The first piston surface 102 is fixed to the surface of the limiting rod 103, and the spherical valve 201r is rotatably connected inside the limiting rod 103.

[0048] The limiting rod 103 is used to support the position of the first piston surface 102 to ensure that the first piston surface 102 does not shake and can cooperate with the spherical valve 201r to control the air pressure inside the air cylinder 101.

[0049] Specifically, a fixed plate surface 104 and a second piston surface 105 are fixed to the surface of the limiting rod 103. The fixed plate surface 104 is fixed to the surface of the limiting rod 103, and the second piston surface 105 is fixed to the surface of the limiting rod 103.

[0050] The fixed plate surface 104 is used to slowly release the air pressure inside the first piston surface 102 to ensure the normal operation of the air cylinder 101. The second piston surface 105 can cooperate with the first piston surface 102. When multiple air pressures are required, the air pressure can be discharged from the first piston surface 102 to the second piston surface 105 through the cooperation of the spherical valve 201r and the limiting rod 103, thereby increasing the air pressure inside the air cylinder 101 and improving the production quality and stability of the products by the air cylinder 101.

[0051] Specifically, a support plate 106 is fixed to the top of the limiting rod 103.

[0052] The support plate 106 is used to fix the position of the air cylinder 101 to ensure the normal use of the air cylinder 101.

[0053] During use, when it is necessary to adjust the air pressure in the demolding cylinder, first squeeze the limit plate 301e to release the limit of the limit plate 301e on the moving rod 301a, and then push the moving rod 301a to move by the pushing block 301b, so that the moving rod 301a compresses the compression spring 201e. After the pushing block 301b moves a certain distance, the pushing block 301b can contact the connecting rod 201d, so that the connecting rod 201d moves, and the connecting rod 201d can push the rotating rod 201c to move. When the rotating rod 201c moves, through the cooperation of the sliding groove V opened on the surface and the limit block 201g, the rotating rod 201c can rotate, so that the rotating rod 201c can drive the support rod 201i to rotate through the inclined surface clamping groove 201h, and the support rod 201i can drive the rotating block 201k to rotate, so that the helical gear 201m in the rotating block 201k can drive the rotating column 201n to rotate through the movable block 201o, so that the rotating column 201n can drive the fixed rod 201q to rotate, and the fixed rod 201q can drive the spherical valve 201r to rotate in the limit rod 103 at the same time, so as to control the air pressure in the cylinder 101. When the pushing of the pushing block 301b to move is cancelled, at this time, the compression spring 201e can push the moving rod 301a to move, so that the moving rod 301a slides outwards, and the pushing block 301b is disengaged from the contact with the connecting rod 201d, so that the connecting rod 201d can drive the rotating rod 201c to move outwards, so that the sliding groove V opened on the surface of the rotating rod 201c can rotate reversely through the limit block 201g, and the inclined surface clamping groove 201h drives the support rod 201i to rotate reversely at the same time, and the support rod 201i drives the rotating block 201k to rotate reversely, so that the helical gear 201m in the rotating block 201k rotates reversely. When the helical gear 201m rotates reversely, the helical gear 201m will squeeze the position of the movable block 201o, so the helical gear 201m cannot mesh with the movable block 201o, and the movable block 201o will not rotate reversely and cannot drive the rotating column 201n to rotate, so as to ensure the control of the air pressure in the cylinder 101 by the spherical valve 201r, ensure that the force during the demolding process can act on the mold stably and accurately, and improve the production quality and stability of the product.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
