Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap production, in particular to a mold for a plastic beverage cap which is easy to demould. Background Art

[0002] The bottle cap has good sealing properties and can effectively prevent air from entering the bottle, thus preventing food, medicine and other easily contaminated items from coming into contact with ambient air. At the same time, the bottle cap can prevent dust, bacteria, insects, etc. from entering the bottle, thus preventing the items in the bottle from being contaminated by the outside world.

[0003] Because the bottle cap is provided with threads inside, the bottle cap cannot be directly removed from the mold during the production process like other general mold products. During the production process of some existing bottle caps, it is necessary to make the mold sleeved on the lower pressing block collide with a special plate, and the plate provides an obstacle for the bottle cap to rotate the bottle cap, so as to remove the bottle cap from the lower pressing block. However, when the device rotates at a fast speed in this way of removing the bottle cap, the collision generated when the bottle cap contacts the plate will be relatively large, which may cause certain damage to the bottle cap, thereby reducing the yield of the product. In order to solve this technical problem, the utility model proposes a mold for a plastic beverage cap that is easy to demould. Utility Model Content

The base 1 can fix the position of the motor 2 so that the motor 2 will not rotate when started. The base 1 can fix the position of the inclined plate 3, and the inclined plate 3 is a spirally rising plate.

[0024] The output end of the motor 2 is connected to a turntable 4, and the outer surface of the turntable 4 is connected to a limit block 5. The motor 2 will fix the position of the turntable 4, and when the motor 2 is started, the turntable 4 will rotate. The turntable 4 will fix the position of the limit block 5, and when the turntable 4 rotates, the limit block 5 will move.

[0025] The limit block 5 is internally connected to a rotating rod 6 for rotation, and a slide groove 7 is provided inside the rotating rod 6. The limit block 5 will limit the position of the rotating rod 6, and when the limit block 5 moves, the rotating rod 6 will move with it. The inner wall of the slide groove 7 is relatively smooth, and other objects will be subject to less friction when moving on the inner wall of the slide groove 7.

[0026] The outer surface of the rotating rod 6 is slidably connected to a gear 8, and the outer surface of the gear 8 is meshed with a toothed plate 9. The rotating rod 6 will limit the position of the gear 8, and when the rotating rod 6 moves, it will move with the gear 8. The gear 8 will rotate under the action of the toothed plate 9. A blocking cover is provided on the upper surface of the turntable 4, which will limit the position of the gear 8 and prevent the gear 8 from moving up and down.

[0027] The outer surface of the rotating rod 6 is slidably connected with a push plate 10, and the upper surface of the push plate 10 is connected with a limiting rod 11. The outer surface of the rotating rod 6 is rotatably connected with a mold 12. The push plate 10 can reduce the vibration generated when the rotating rod 6 rotates. The push plate 10 will fix the position of the limiting rod 11, and will rotate with the push plate 10 when the limiting rod 11 rotates. Under the action of the limiting rod 11, stripes will be formed on the surface of the bottle cap. After the bottle cap is cooled, the limiting rod 11 will rotate with the bottle cap, and the rotating rod 6 will contact the inner wall of the mold 12.

[0028] The upper surface of the turntable 4 is connected to a support column 13, and the outer surface of the support column 13 is connected to a transmission disk 14. A stamping mechanism 15 is arranged above the base 1. The turntable 4 will fix the position of the support column 13, and when the turntable 4 rotates, it will rotate with the support column 13. The support column 13 will fix the position of the transmission disk 14, and the transmission disk 14 will rotate through the rotation of the support column 13.

[0029] The stamping mechanism 15 includes a support plate 1501, the bottom surface of the support plate 1501 is connected to the upper surface of the support column 13, and a cylinder 1502 is installed on the upper surface of the support plate 1501. The support column 13 will fix the position of the support plate 1501, and when the support column 13 rotates, it will rotate with the support plate 1501, and the support column 13 will fix the position of the cylinder 1502.

[0030] The output end of the cylinder 1502 is connected to a pressing block 1503, and the outer surface of the pressing block 1503 is connected to a blocking plate 1504. The cylinder 1502 will fix the position of the pressing block 1503, and when the cylinder 1502 is started, it will move the pressing block 1503. The outer surface of the pressing block 1503 is provided with threads, and the threads inside the bottle cap are made by the threads prevented by the pressing block 1503. The pressing block 1503 will fix the position of the blocking plate 1504, and the blocking plate 1504 can prevent the raw material from overflowing from the mold 12.

[0031] The upper surface of the inclined plate 3 is slidably connected to the bottom surface of the rotating rod 6, and the outer surface of the limit block 5 is slidably connected to the inside of the base 1. When the rotating rod 6 moves on the inclined plate 3, the rotating rod 6 will move upward along the inclined plate 3, and the bottle cap will be pushed out of the mold 12 by the movement of the rotating rod 6, and the base 1 will limit the position of the limit block 5.

[0032] The interior of the gear 8 is slidably connected to the inner wall of the slide groove 7, and the outer surface of the gear 8 is meshed with the outer surface of the tooth plate 9. When the gear 8 rotates, the slide groove 7 can lead the rotating rod 6 to rotate, and the tooth plate 9 can cause the gear 8 to rotate.

[0033] The outer surface of the push plate 10 is connected to the inner rotation of the mold 12, the outer surface of the limit rod 11 is connected to the inner rotation of the mold 12, the outer surface of the rotating rod 6 is connected to the outer surface of the limit rod 11 in a sliding manner, and the mold 12 will limit the position of the push plate 10 so that the push plate 10 can only rotate but cannot move upward. The mold 12 will limit the position of the limit rod 11, and a plate is provided above the rotating rod 6, and the limit rod 11 is rotated by rotating the plate.

[0034] The outer surface of the transmission disk 14 is slidably connected to the outer surface of the mold 12, and the outer surface of the base 1 is slidably connected to the outer surface of the mold 12. The position of the mold 12 is limited by the transmission disk 14 and the base 1, so that the moving position of the mold 12 will not deviate.

[0035] Working principle: When using the device, first, it is necessary to put it into the mold 12, and then the cylinder 1502 above the mold 12 will start, so that the lower pressure block 1503 is pressed into the mold 12, and then the motor 2 will make the turntable 4 move with the limit block 5, and the movement of the limit block 5 will move the rotating rod 6, and the rotating rod 6 will move with the mold 12 and the gear 8. When the gear 8 moves to the position meshing with the tooth plate 9, the gear 8 will rotate, and the rotation of the gear 8 will rotate with the rotating rod 6. At the same time, the rotating rod 6 will move upward under the action of the inclined plate 3, and the cylinder 1502 will rise with the rise of the rotating rod 6. When the rotating rod 6 rotates, it will rotate with the limit rod 11, so that the bottle cap is twisted off the lower pressure block 1503, and then the rotating rod 6 pushes out of the mold 12, thereby completing the demolding of the bottle cap.
