Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap processing and molding, in particular to a molding die for processing high-strength bottle caps. Background Art

[0002] Bottle caps are used in cans of various beverages, medicines, etc. to seal the bottles. In the existing molding technology for bottle cap processing, compression molding and injection molding are mostly used.

[0003] In the compression molding process, the mixed material is first placed in the compression molding machine, where it is heated to a semi-plasticized state. The material is then extruded into a predetermined amount through a feeding mechanism into a mold. The upper and lower molds are then closed and compressed into bottle caps. The lower mold is then removed, leaving the compression-molded bottle caps in the upper mold. The bottle caps pass through a rotating disk, where the rotation of the rotating disk and the bottle caps removes the bottle caps from the upper mold. After compression molding, the bottle caps rotate on the anti-theft ring processing assembly, where a blade cuts the edge of the bottle caps into anti-theft rings connected by multiple points. The bottle cap processing is completed. When producing high-strength, thicker bottle caps, during the above operation, when the bottle caps pass through the rotating disk, due to their thickness, the rotation of the rotating disk and the bottle caps alone cannot ensure that all the produced bottle caps are removed from the upper mold. The bottle caps may remain stuck to the upper mold, affecting processing efficiency. At the same time, when processing the anti-theft rings on the bottle caps, a separate transmission mechanism is required to control the rotation of the upper mold, which increases the complexity of the internal circuit of the mold and reduces practicality.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 5 As shown in this embodiment, a high-strength bottle cap processing forming mold includes a fixed base 1, a rotating base 2 is rotatably installed in the middle of the fixed base 1, a lower mold 3 is installed in the middle of the rotating base 2 in a ring array with the central axis of the rotating base 2 as the axis, and the lower mold 3 can be lifted and lowered, and an upper mold 4 is fixedly installed in the top of the rotating base 2 in a ring array with the central axis of the rotating base 2 as the axis, and a connecting rod 5 is rotatably and slidably installed in the middle of the upper mold 4, and a push block 6 is fixedly installed at the bottom of the connecting rod 5, and the push block 6 can be lifted and lowered. A rubber wheel 7 is fixedly installed on the top of the connecting rod 5, and an arc-shaped rubber block 8 is installed on the top of the fixing seat 1. The arc-shaped rubber block 8 is in friction contact with the rubber wheel 7. After the bottle cap is demoulded, the rubber wheel 7 on the top of the connecting rod 5 will be in friction contact with the arc-shaped rubber block 8. The friction force between the rubber wheel 7 and the arc-shaped rubber block 8 will drive the connecting rod 5 to rotate, and the push block 6 will frictionally rotate the bottle cap placed on the platform of the anti-theft ring processing assembly to achieve synchronous processing of the anti-theft ring, reduce the complexity of the device, and improve the practicality of the device.

[0022] like Figures 1 to 5 As shown, a fixed block 9 is fixedly installed on the top of the fixed seat 1, and an extrusion rod 10 is fixedly installed on one end of the fixed block 9. The bottom end of the extrusion rod 10 is provided with a first extrusion fillet 11, and the top of the connecting rod 5 is provided with a second extrusion fillet 12. The first extrusion fillet 11 is in extrusion contact with the second extrusion fillet 12.

[0023] After being pressed into the bottle cap in the mold, as the rotating seat 2 rotates, when the bottle cap passes the rotating disk, the upper mold 4 will move to the extrusion rod 10, and the extrusion of the first extrusion fillet 11 and the second extrusion fillet 12 will drive the connecting rod 5 to move downward, and the pushing block 6 will push the bottle cap, and the bottle cap will be removed from the upper mold 4, thereby improving the stability of the bottle cap demoulding.

[0024] like Figures 1 to 5As shown, a receiving groove 13 for receiving the push block 6 is provided at the bottom of the upper mold 4 .

[0025] The receiving groove 13 can receive the pushing block 6 to prevent the pushing block 6 from interfering with the forming of the bottle cap during the extrusion forming of the bottle cap.

[0026] like Figures 1 to 5 As shown, a piston hole 14 is provided at the bottom of the upper mold 4 corresponding to the upper position of the receiving groove 13 , and a sealing piston 15 is installed at the bottom end of the connecting rod 5 corresponding to the position of the piston hole 14 .

[0027] The inner space of the upper mold 4 can be sealed by the sealing piston 15 to prevent cooling water from flowing out from the bottom of the upper mold 4 .

[0028] like Figures 1 to 5 As shown, a fixed circular plate 16 is fixedly installed at the end of the connecting rod 5 corresponding to the upper position of the sealing piston 15, and a return spring 17 is sleeved at the outer side of the connecting rod 5 corresponding to the lower position of the fixed circular plate 16. The top of the return spring 17 is fixedly connected to the fixed circular plate 16, and the bottom end of the return spring 17 is fixedly installed with a connecting circular plate 18, which is slidably installed on the outer side of the connecting rod 5.

[0029] When the connecting rod 5 is controlled to move downward, the return spring 17 will be compressed. After the bottle cap is demoulded from the upper mold 4, the return spring 17 will lift the connecting rod 5 and drive the connecting rod 5 to return to its original position.

[0030] like Figures 1 to 5 As shown, a water cavity 19 is opened inside the upper mold 4, and a water inlet pipe 20 and a water outlet pipe 21 are symmetrically installed on the top of the water cavity 19.

[0031] Cooling water is filled into the water cavity 19 through the water inlet pipe 20. At the same time, the used cooling water in the water cavity 19 is discharged through the water outlet pipe 21 to achieve cooling of the bottle cap after compression molding. The circulation principle of the cooling water is the same as the circulation principle of the cooling water in the existing compression molding mold.

[0032] The utility model provides a high-strength bottle cap forming die, the specific working principle is as follows:

[0033] When the device is in use, the melted raw material is squeezed into the lower mold 3 through the feeding mechanism. As the rotating base 2 rotates, the lower mold 3 is controlled to move up and close with the upper mold 4, and the bottle cap is pressed into the mold. As the rotating base 2 rotates, the lower mold 3 moves down, and the molded bottle cap remains in the upper mold 4. When the bottle cap passes the rotating disk, the upper mold 4 will move to the extrusion rod 10. The extrusion of the first extrusion fillet 11 and the second extrusion fillet 12 will drive the connecting rod 5 to move down, and the push block 6 will push the bottle cap, and the bottle cap will be removed from the upper mold 4.

[0034] After the bottle cap is demoulded, the rubber wheel 7 on the top of the connecting rod 5 will come into friction contact with the arc-shaped rubber block 8. The friction force between the rubber wheel 7 and the arc-shaped rubber block 8 will drive the connecting rod 5 to rotate, and the push block 6 will frictionally rotate the bottle cap placed on the platform of the anti-theft ring processing assembly to achieve synchronous processing of the anti-theft ring.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
