[0016] A method for using a quick demolding device for plastic suction products includes the following steps:

[0017] S1: During operation, first place the flat plastic hard sheet on the top end of the bottom mold, and then drive the top mold to move downward through the cylinder, so that the convex part at the bottom end of the top mold presses the plastic hard sheet into the groove opened at the top of the bottom mold;

[0018] S2: During the downward movement of the top mold, the first clamping plate is driven to move downward through the first connecting shaft. The movement of the first clamping plate drives the movement of the first connecting plate, and the movement of the first connecting plate drives the movement of the wedge block. When the inclined surface at the bottom of the wedge block contacts the top end of the second connecting plate, it slides into the first connecting plate under force. At the same time, the first spring is deformed under force to store elastic potential energy. When the wedge block moves below the second connecting plate, the elastic potential energy is released through the first spring to reset the wedge block, causing the wedge block to move to the bottom end of the second connecting plate, thereby connecting the first clamping plate and the second clamping plate and clamping the edge of the plastic sheet.

[0019] S3: After thermoforming, the top mold is driven to move upward and reset by the air cylinder. Similarly, the movement of the top mold drives the first clamping plate and the second clamping plate to clamp the four sides of the plastic sheet and move upward through the first connecting shaft, so that it is separated from the bottom mold.

[0020] S4: At the same time, the movement of the second clamping plate drives the second connecting shaft to move upward. When the second connecting shaft moves upward, the third spring is deformed under force to store elastic potential energy.

[0021] S5: At the same time, the movement of the second connecting shaft drives the slider to slide inside the spiral groove, prompting the first rotating shaft to rotate. The rotation of the first rotating shaft drives the rotation of the first bevel gear, the rotation of the first bevel gear drives the rotation of the second bevel gear, the rotation of the second bevel gear drives the rotation of the second rotating shaft, the rotation of the second rotating shaft drives the rotation of the cam, and the protrusion of the cam contacts the movable plate to drive the movable plate to move upward. The movement of the movable plate drives the knocking rod to move upward and knock the inner wall of the bottom mold, thereby prompting the inside of the bottom mold to vibrate and assisting in demolding.

[0022] S6: At the same time, the movement of the first clamping plate drives the movement of the first connecting plate, the movement of the first connecting plate drives the movement of the moving plate, and the movement of the moving plate drives the movement of the convex block. When the convex block contacts the guiding block, it moves to one side under force. The movement of the convex block drives the movement of the wedge block through the movement of the moving plate, causing the wedge block to slide into the first connecting plate, facilitating the separation of the first clamping plate and the second clamping plate and loosening the plastic sheet.

[0023] S7: After the first clamping plate and the second clamping plate are separated, the elastic potential energy is released through the third spring to move the second connecting shaft downward, thereby moving the second clamping plate downward to reset.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention is provided with a clamping assembly and a connecting assembly cooperating with each other. During operation, first, the flat plastic sheet is placed on the top of the bottom mold. Then, the top mold is driven by a cylinder to move downward, and the convex part at the bottom of the top mold presses the plastic sheet into the groove opened at the top of the bottom mold. During the downward movement of the top mold, the first clamping plate is driven to move downward through the first connecting shaft. The movement of the first clamping plate drives the movement of the first connecting plate, and the movement of the first connecting plate drives the movement of the wedge block. When the inclined surface at the bottom of the wedge block contacts the top end of the second connecting plate, it slides into the first connecting plate under force, and at the same time, the first spring is deformed under force to store elastic potential energy. When the wedge block moves below the second connecting plate, the elastic potential energy is released through the first spring to reset the wedge block, causing the wedge block to move to the bottom end of the second connecting plate, thereby connecting the first clamping plate and the second clamping plate and clamping the edge of the plastic sheet. After thermoforming, the top mold is driven by the cylinder to move upward and reset. Similarly, the movement of the top mold drives the first clamping plate and the second clamping plate to clamp the four sides of the plastic sheet and move upward through the first connecting shaft, so that it can be separated from the bottom mold, facilitating rapid demolding and improving the demolding efficiency.

[0026] 2. Through the setting of the guiding block in the present invention, after thermoforming, when the top mold moves upward, similarly, the movement of the top mold drives the first clamping plate to move through the first connecting shaft. The movement of the first clamping plate drives the movement of the first connecting plate, and the movement of the first connecting plate drives the movement of the moving plate. The movement of the moving plate drives the movement of the convex block. When the convex block contacts the guiding block, it moves to one side under force. The movement of the convex block drives the movement of the wedge block through the movement of the moving plate, causing the wedge block to slide into the first connecting plate, facilitating the separation of the first clamping plate and the second clamping plate, thereby releasing the plastic sheet and facilitating its removal.

[0027] 3. Through the setting of the vibration assembly in the present invention, when the top mold moves upward and resets, driving the first clamping plate and the second clamping plate to move upward, the movement of the second clamping plate drives the movement of the second connecting shaft. The movement of the second connecting shaft drives the slider to slide inside the spiral groove, prompting the first rotating shaft to rotate. The rotation of the first rotating shaft drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the second rotating shaft. The rotation of the second rotating shaft drives the rotation of the cam. The protrusion of the cam contacts the movable plate and drives the movable plate to move upward. The movement of the movable plate drives the knocking rod to move upward and knock on the inner wall of the bottom mold, thereby prompting vibration inside the bottom mold, which helps to break the tight contact between the product and the inner cavity of the bottom mold, making it easier for the product to be separated from the mold, thus improving the demolding efficiency.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] As Figures 1 to 6 shown, in the embodiment of the present invention, a rapid demolding device for plastic suction products includes a top plate 1. A cylinder 2 is installed at the top end of the top plate 1. The output end of the cylinder 2 is connected to a top mold 3. A bottom mold 4 is arranged below the top mold 3. A clamping assembly is arranged between the top mold 3 and the bottom mold 4. A vibration assembly is arranged inside the bottom mold 4. The top ends of the four corners of the bottom mold 4 are all fixedly connected with guide shafts 5. The four guide shafts 5 pass through the inner wall of the top mold 3 and are fixedly installed with the top plate 1. The top mold 3 is slidably connected with the guide shafts 5;

[0037] The clamping assembly includes a first clamping plate 6 and a second clamping plate 7 arranged between the top mold 3 and the bottom mold 4. The first clamping plate 6 and the second clamping plate 7 are connected by a connecting assembly. The top end of the first clamping plate 6 is fixedly installed with a first connecting shaft 8. The first connecting shafts 8 are evenly distributed. The top end of each first connecting shaft 8 is embedded inside the top mold 3;

[0038] The connecting component includes a first connecting plate 9 fixedly installed on the side wall of the first clamping plate 6. A moving plate 10 is slidably installed inside the first connecting plate 9. A first spring 13 is arranged on one side of the moving plate 10. A wedge block 11 is fixedly installed at the bottom end of the moving plate 10. A second connecting plate 16 is arranged below the wedge block 11. The second connecting plate 16 is fixedly installed on the side wall of the second clamping plate 7.

[0039] During operation, first place the flat plastic sheet on the top of the bottom mold 4, and then drive the top mold 3 to move downward through the air cylinder 2, so that the convex part at the bottom end of the top mold 3 presses the plastic sheet into the groove opened at the top of the bottom mold 4.

[0040] During the downward movement of the top mold 3, the first clamping plate 6 is driven to move downward through the first connecting shaft 8. The movement of the first clamping plate 6 drives the movement of the first connecting plate 9. The movement of the first connecting plate 9 drives the movement of the wedge block 11. When the inclined surface at the bottom of the wedge block 11 contacts the top end of the second connecting plate 16, the wedge block 11 slides into the first connecting plate 9 under force. At the same time, the first spring 13 is deformed under force to store elastic potential energy. When the wedge block 11 moves below the second connecting plate 16, the elastic potential energy is released through the first spring 13 to reset the wedge block 11, so that the wedge block 11 moves to the bottom end of the second connecting plate 16, thereby connecting the first clamping plate 6 and the second clamping plate 7 and clamping the edge of the plastic sheet.

[0041] After thermoforming, the top mold 3 is driven to move upward and reset through the air cylinder 2. Similarly, when the top mold 3 moves, the first clamping plate 6 and the second clamping plate 7 clamp the four sides of the plastic sheet and move upward through the first connecting shaft 8, so that it is separated from the bottom mold 4, which is convenient for rapid demolding and improves the demolding efficiency.

[0042] As Figure 2 shown, the first connecting shaft 8 is slidably connected to the top mold 3.

[0043] When the bottom end of the first clamping plate 6 contacts the top end of the second clamping plate 7 after the top mold 3 moves downward, the top mold 3 continues to move so that the first connecting shaft 8 can slide inside the top mold 3.

[0044] As Figure 2 shown, a second spring 17 is arranged at the top end of the first connecting shaft 8. The second spring 17 is installed inside the top mold 3.

[0045] Due to the elastic potential energy of the second spring 17, the first connecting shaft 8 always maintains a downward movement trend. At the same time, when the first clamping plate 6 and the second clamping plate 7 are in contact and clamp the plastic sheet, due to the elasticity of the second spring 17, it can prevent the clamping force between the first clamping plate 6 and the second clamping plate 7 from being too tight during the deformation of the plastic sheet, and the edge of the plastic sheet is prone to cracking.

[0046] As Figures 1 to 3As shown, a convex block 12 is fixedly installed on one side of the wedge block 11. A guiding block 14 is arranged at one end of the convex block 12. The top end of the guiding block 14 is fixedly connected with a mounting plate 15, and the mounting plate 15 is fixedly installed at the bottom end of the top plate 1.

[0047] After thermoforming, when the top mold 3 moves upward, similarly, the movement of the top mold 3 drives the movement of the first clamping plate 6 through the first connecting shaft 8. The movement of the first clamping plate 6 drives the movement of the first connecting plate 9. The movement of the first connecting plate 9 drives the movement of the moving plate 10. The movement of the moving plate 10 drives the movement of the convex block 12. When the convex block 12 contacts the guiding block 14, it is forced to move to one side. The movement of the convex block 12 drives the movement of the wedge block 11 through the movement of the moving plate 10, so that the wedge block 11 slides into the first connecting plate 9, facilitating the separation of the first clamping plate 6 and the second clamping plate 7, thereby releasing the plastic sheet and facilitating its removal.

[0048] As Figure 2 and Figure 4 shown, the bottom end of the second clamping plate 7 is fixedly connected with a second connecting shaft 18, and the second connecting shaft 18 is slidably installed inside the bottom mold 4.

[0049] Limit the movement track of the second clamping plate 7 moving up and down.

[0050] As Figure 2 、 Figure 4 and Figure 6 shown, a third spring 19 is arranged on the outer wall of the second connecting shaft 18.

[0051] When the top mold 3 moves upward and resets, the first clamping plate 6 and the second clamping plate 7 clamp the plastic sheet and move upward. The movement of the second clamping plate 7 drives the second connecting shaft 18 to move upward. When the second connecting shaft 18 moves upward, the third spring 19 is deformed under force and stores elastic potential energy;

[0052] After the first clamping plate 6 and the second clamping plate 7 are separated, the elastic potential energy is released through the third spring 19 to make the second connecting shaft 18 move downward, so that the second clamping plate 7 moves downward and resets.

[0053] As Figure 2 and Figure 4As shown in the figure, the vibration assembly includes a movable plate 27 disposed inside the bottom mold 4. The movable plate 27 is slidably connected to the bottom mold 4. Limiting plates 30 are evenly installed inside the movable plate 27. A knocking rod 28 is fixedly connected to the top end of the limiting plate 30. A second rotating shaft 25 is disposed below the movable plate 27. A cam 26 is fixedly installed on the outer wall of the second rotating shaft 25. One end of the second rotating shaft 25 is fixedly connected to a second bevel gear 24. The top end of the second bevel gear 24 is meshed with a first bevel gear 23. A first rotating shaft 20 is fixedly installed at the top end of the first bevel gear 23. A spiral groove 21 is formed inside the first rotating shaft 20. A slider 22 is slidably connected to the inner wall of the spiral groove 21. The slider 22 is fixedly installed on the inner wall of the second connecting shaft 18.

[0054] When the top mold 3 moves upward to reset and drives the first clamping plate 6 and the second clamping plate 7 to move upward, the movement of the second clamping plate 7 drives the movement of the second connecting shaft 18. The movement of the second connecting shaft 18 drives the slider 22 to slide inside the spiral groove 21, prompting the first rotating shaft 20 to rotate. The rotation of the first rotating shaft 20 drives the rotation of the first bevel gear 23. The rotation of the first bevel gear 23 drives the rotation of the second bevel gear 24. The rotation of the second bevel gear 24 drives the rotation of the second rotating shaft 25. The rotation of the second rotating shaft 25 drives the rotation of the cam 26. The protrusion of the cam 26 contacts the movable plate 27 and drives the movable plate 27 to move upward. The movement of the movable plate 27 drives the knocking rod 28 to move upward and knock the inner wall of the bottom mold 4, thereby prompting vibration inside the bottom mold 4, which helps to break the close contact between the product and the inner cavity of the bottom mold 4, making it easier for the product to be separated from the mold, and thus improving the demolding efficiency.

[0055] As Figure 2 and Figure 4 shown, the second connecting shaft 18 is sleeved outside the first rotating shaft 20.

[0056] As Figure 4 shown, the limiting plate 30 is slidably connected to the movable plate 27, and a fourth spring 29 is disposed on the outer wall of the limiting plate 30.

[0057] During the knocking process, the elastic setting can absorb part of the impact force, reduce the direct collision between the knocking rod 28 and the bottom mold 4, thereby protecting the bottom mold 4 and the knocking rod 28 from damage, helping to extend the service life of the equipment, and reducing the maintenance cost.

[0058] A method for using a rapid demolding device for plastic - blister products includes the following steps:

[0059] S1: During operation, first place the flat plastic sheet on the top end of the bottom mold 4, and then drive the top mold 3 to move downward through the cylinder 2, so that the protrusion at the bottom end of the top mold 3 presses the plastic sheet into the groove formed at the top of the bottom mold 4;

[0060] S2: During the downward movement of the top mold 3, the first clamping plate 6 is driven to move downward through the first connecting shaft 8. The movement of the first clamping plate 6 drives the movement of the first connecting plate 9. The movement of the first connecting plate 9 drives the movement of the wedge block 11. When the inclined surface at the bottom of the wedge block 11 contacts the top of the second connecting plate 16, it slides into the first connecting plate 9 under force. At the same time, the first spring 13 is deformed under force to store elastic potential energy. When the wedge block 11 moves to the bottom of the second connecting plate 16, the elastic potential energy is released by the first spring 13 to reset the wedge block 11, so that the wedge block 11 moves to the bottom end of the second connecting plate 16, thereby connecting the first clamping plate 6 and the second clamping plate 7 and clamping the edge of the plastic hard sheet;

[0061] S3: After the vacuum forming, the top mold 3 is driven by the cylinder 2 to move up and reset. Similarly, the top mold 3 moves through the first connecting shaft 8 to drive the first clamping plate 6 and the second clamping plate 7 to clamp the four sides of the plastic hard sheet and move it up to separate it from the bottom mold 4;

[0062] S4: At the same time, the second clamping plate 7 moves the second connecting shaft 18 upward, and when the second connecting shaft 18 moves upward, the third spring 19 is deformed by force to store elastic potential energy;

[0063] S5: At the same time, the movement of the second connecting shaft 18 drives the slider 22 to slide inside the spiral groove 21, causing the first rotating shaft 20 to rotate, and the rotation of the first rotating shaft 20 drives the rotation of the first bevel gear 23, and the rotation of the first bevel gear 23 drives the rotation of the second bevel gear 24, and the rotation of the second bevel gear 24 drives the rotation of the second rotating shaft 25, and the rotation of the second rotating shaft 25 drives the rotation of the cam 26, and the protrusion of the cam 26 contacts the movable plate 27 to drive the movable plate 27 to move upward, and the movement of the movable plate 27 drives the knocking rod 28 to move upward to knock the inner wall of the bottom mold 4, thereby causing the bottom mold 4 to vibrate inside and assist demoulding;

[0064] S6: At the same time, the movement of the first clamping plate 6 drives the movement of the first connecting plate 9, the movement of the first connecting plate 9 drives the movement of the moving plate 10, the movement of the moving plate 10 drives the movement of the protrusion 12, when the protrusion 12 contacts the guide block 14, it is forced to move to one side, the movement of the protrusion 12 drives the movement of the wedge block 11 through the movement of the moving plate 10, so that the wedge block 11 slides into the first connecting plate 9, so as to separate the first clamping plate 6 and the second clamping plate 7, and loosen the plastic hard sheet;

[0065] S7: When the first clamping plate 6 and the second clamping plate 7 are separated, the elastic potential energy is released by the third spring 19 to move the second connecting shaft 18 downward, thereby causing the second clamping plate 7 to move downward and reset.

[0066] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.

A method for using a rapid demoulding device for blister products, the method being applicable to the rapid demoulding device for blister products as claimed in claims 1 to 9, characterized in that: The following steps are involved: S1: When working, firstly place a flat plastic sheet on the top of the bottom mold (4), then drive the top mold (3) downward through the cylinder (2), so that the raised part at the bottom of the top mold (3) presses the plastic sheet into the groove opened at the top of the bottom mold (4); S2: During the downward movement of the top mold (3), the first clamping plate (6) is driven to move downward through the first connecting shaft (8), the movement of the first clamping plate (6) drives the movement of the first connecting plate (9), and the movement of the first connecting plate (9) drives the movement of the wedge block (11). When the inclined surface at the bottom of the wedge block (11) contacts the top of the second connecting plate (16), it slides into the first connecting plate (9) under force, and at the same time, the first spring (13) is deformed under force to store elastic potential energy. When the wedge block (11) moves to the bottom of the second connecting plate (16), the elastic potential energy is released by the first spring (13) to reset the wedge block (11), so that the wedge block (11) moves to the bottom of the second connecting plate (16), thereby connecting the first clamping plate (6) and the second clamping plate (7) and clamping the edge of the plastic hard sheet; S3: After the vacuum forming, the top mold (3) is driven by the cylinder (2) to move upward and reset. Similarly, the top mold (3) moves through the first connecting shaft (8) to drive the first clamping plate (6) and the second clamping plate (7) to clamp the four sides of the plastic hard sheet and move upward, so that it is separated from the bottom mold (4); S4: At the same time, the second clamping plate (7) moves with the second connecting shaft (18) upward, and when the second connecting shaft (18) moves upward, the third spring (19) is deformed by force to store elastic potential energy; S5: At the same time, the movement of the second connecting shaft (18) drives the slider (22) to slide inside the spiral groove (21), causing the first rotating shaft (20) to rotate, and the rotation of the first rotating shaft (20) drives the rotation of the first bevel gear (23), and the rotation of the first bevel gear (23) drives the rotation of the second bevel gear (24), and the rotation of the second bevel gear (24) drives the rotation of the second rotating shaft (25), and the rotation of the second rotating shaft (25) drives the rotation of the cam (26), and the protrusion of the cam (26) contacts the movable plate (27) and drives the movable plate (27) to move upward, and the movement of the movable plate (27) drives the knocking rod (28) to move upward and knock the inner wall of the bottom mold (4), thereby causing the inside of the bottom mold (4) to vibrate and assist in demoulding; S6: At the same time, the movement of the first clamping plate (6) drives the movement of the first connecting plate (9), the movement of the first connecting plate (9) drives the movement of the moving plate (10), the movement of the moving plate (10) drives the movement of the protrusion (12), when the protrusion (12) contacts the guide block (14), it is forced to move to one side, the movement of the protrusion (12) drives the movement of the wedge block (11) through the movement of the moving plate (10), so that the wedge block (11) slides into the first connecting plate (9), so as to facilitate the separation of the first clamping plate (6) and the second clamping plate (7), and loosen the plastic hard sheet; S7: When the first clamping plate (6) and the second clamping plate (7) are separated, the elastic potential energy is released by the third spring (19) to move the second connecting shaft (18) downward, thereby causing the second clamping plate (7) to move downward and reset.
