[0002] As the core of the manufacturing industry, a mold is a cavity tool with a certain shape and size, which is used in conjunction with various systems or auxiliary mechanisms in the mold to fill various high-temperature liquid materials (such as plastics or metal alloys) into the mold cavity, and industrial parts with specific shapes, sizes, functions, and qualities can be produced.

[0003] During the molding process of some bottle caps, it is necessary to print specific marks or structures on the bottle caps. These specific marks or structures have relative angle requirements with the starting point of the thread of the bottle cap. After the bottle cap is tightened with the bottle body, the specific marks or structures on the bottle cap can be aligned with the front of the bottle body. When assembling such molds, they need to be fixed to the compression molding machine according to specific angle standards. Currently, the assembly process of the existing compression molding molds for bottle caps takes a long time, and the positioning accuracy of the molds is poor. Therefore, there is an urgent need for a compression molding mold for bottle caps that can meet the mass production of bottle caps with specific marks or structures, achieve rapid assembly, and improve the positioning accuracy at the same time.

[0030] Embodiment 1:

[0031] Please refer to Figures 1-5 , this embodiment provides a bottle cap compression molding die, including a die core assembly 20 and a fixing assembly 10.

[0032] The fixing component 10 is used to fix the core component 20 in a compression molding machine; the fixing component 10 includes an upper mold base 11 and a power shaft sleeve 12; both ends of the power shaft sleeve 12 respectively form a first end 121 and a second end 122, an installation cavity 123 is axially formed inside the power shaft sleeve 12, and the installation cavity 123 communicates with the first end 121 and the second end 122; the first end 121 of the power shaft sleeve 12 is fixed to the upper mold base 11 by bolts.

[0033] The core component 20 is inserted into the installation cavity 123; a positioning component 30 is arranged at the connection between the core component 20 and the power shaft sleeve 12, and the positioning component 30 slidably connects the core component 20 in the installation cavity 123 at a preset angle, and restricts the rotation of the core component 20 in the installation cavity 123 through the positioning component 30.

[0034] Based on the above structure, by arranging the positioning component 30 between the fixing component 10 and the core component 20; the fixing component 10 installs and fixes the bottle cap compression molding die in the compression molding machine, and the core component 20 performs the compression molding of the bottle cap; the positioning component 30 slidably connects the core component 20 in the installation cavity 123 at a preset angle, and at the same time restricts the rotation of the core component 20 relative to the fixing component 10, so that the starting point of the thread of the bottle cap is formed at a preset position according to requirements, so that after the bottle cap is tightened with the bottle body, the specific mark or structure on the bottle cap can be consistent with the front of the bottle body. During installation, the core component 20 can be fixed in the compression molding machine according to a specific angle standard through the connection of the positioning component 30, without repeated debugging and alignment, realizing rapid assembly, and at the same time improving the positioning accuracy.

[0035] Specifically, the positioning component 30 includes a chute 31 and a positioning block 32, the chute 31 is opened on the inner wall of the installation cavity 123, and the length direction of the chute 31 is consistent with the axial direction of the power shaft sleeve 12; the positioning block 32 is fixed to the core component 20; the positioning block 32 is in clearance fit with the chute 31, so that the positioning block 32 can slide along the length direction of the chute 31. An installation port 311 is formed at the end of the chute 31, the installation port 311 is arranged close to the first end 121, and a guiding part is arranged at the installation port 311. During use, the positioning block 32 enters the chute 31 from one end of the installation port 311, which is convenient for disassembly. One side of the positioning block 32 close to the power shaft sleeve 12 is rectangular, and the other side is wedge-shaped. Arc-shaped round corners are arranged around the positioning block 32. Through the cooperation of the arc-shaped round corners and the guiding part, the positioning block 32 is smoothly guided into the chute 31 from the installation port 311, improving the assembly efficiency.

[0036] The core assembly 20 includes a core rod 21, a mold sleeve and a demolding sleeve 23. The mold sleeve includes an outer mold sleeve 221 and an inner mold sleeve 222. Among them, the core rod 21 is responsible for abutting against the top inside the bottle cap, the outer mold sleeve 221 is responsible for pressing the thread of the bottle cap, and the inner mold sleeve 222 is responsible for pressing the inner plug of the bottle cap.

[0037] The core assembly 20 further includes a pneumatic assembly. The pneumatic assembly includes a nozzle and a power shaft 241. The nozzle is fixedly connected to the power shaft 241. The core rod 21 penetrates into the axis of the power shaft 241. One end of the power shaft 241 is fixedly connected to the outer mold sleeve 221. A cylinder can be connected to the nozzle, and the power shaft 241 is driven by the cylinder.

[0038] In this embodiment, the installation groove is opened on the outer side of the power shaft 241. By fixing the positioning block 32 in the installation groove, the power shaft 241 is slidably connected to the installation cavity 123, and at the same time, the rotation of the power shaft 241 in the installation cavity 123 is restricted. The starting point of the thread pressed by the outer mold sleeve 221 is set at a preset angle in the compression molding machine.

[0039] The core assembly 20 further includes a reset assembly 25. The reset assembly 25 includes a first spring, a connecting sleeve and a second spring. The first spring is arranged on the outer wall of the power shaft sleeve 12. The power shaft sleeve 12 and the outer mold sleeve 221 are located inside the connecting sleeve. One end of the first spring abuts against one end of the connecting sleeve. The second spring is located between the inner wall of the connecting sleeve and the outer wall of the outer mold sleeve 221.

[0040] When demolding the bottle cap, there is a clamping groove on the demolding sleeve 23. The demolding sleeve 23 is connected to the guide rod assembly in the compression molding machine through the clamping groove. The guide rod assembly provides power to the demolding sleeve 23, and the demolding sleeve 23 moves downward. At the same time, the outer mold sleeve 221, the inner mold sleeve 222 and the bottle cap also move downward under the drive of the pneumatic assembly. When moving to the limit position (10 mm), the outer mold sleeve 221, the inner mold sleeve 222 and the power shaft 241 no longer move downward. Then, the demolding sleeve 23 continues to move downward by 15 mm. Since the demolding sleeve 23 contacts the bottle cap, the bottle cap is detached from the outer mold sleeve 221 and the inner mold sleeve 222. Finally, the outer mold sleeve 221, the inner mold sleeve 222 and the power shaft 241 are reset by the first spring and the second spring. After the demolding sleeve 23 continues to move downward by 3 mm, the guide rod assembly is also responsible for resetting the demolding sleeve 23.

[0041] The core assembly 20 further includes a cooling assembly 26. The cooling assembly 26 includes a first water nozzle, a second water nozzle and a water pipe. The water pipe penetrates into the core rod 21. The first water nozzle is arranged at the top of the water pipe, and the second water nozzle is arranged at the side of the water pipe. Among them, the first water nozzle is the water inlet, and the second water nozzle is the water outlet. Both the water pipe and the core rod 21 penetrate into the upper mold base 11.

[0042] The fixing component 10 of this embodiment further includes an upper die fixing bushing 13, the upper die fixing bushing 13 is sleeved outside the power shaft sleeve 12, and the end of the upper die fixing bushing 13 is fixedly connected to the upper die base 11.
