Description

Technical Field

[0001] This utility model belongs to the technical field of bottle cap surface treatment processing device, specifically a bottle cap surface treatment positioning mold. Background Technology

[0002] In the bottle cap manufacturing process, in order to achieve a better gloss on the bottle cap surface, after the bottle cap is finished, it needs to be placed on a bottle cap positioning mold, and an oil-based paint is applied to its outer surface. Then, a polishing cloth wheel is used to wipe the outer surface of the bottle cap to give it a better gloss.

[0003] See Figure 3 The existing bottle cap surface treatment positioning mold is a cylindrical part that matches the bottle cap. During processing, the bottle cap is fitted onto the positioning mold with its sidewalls pressed tightly against it. Then, an oil-based paint is applied, and a polishing roller is used to wipe the outer surface of the bottle cap. Because there is a certain gap between the bottle cap and the positioning mold, the oil-based paint will flow down through the opening at the bottom of the bottle cap due to gravity. During the wiping process, the polishing roller will squeeze the bottle cap, causing the gap between the bottle cap and the positioning mold to be compressed and then widened, creating a suction-like effect. As a result, some oil-based paint will enter the bottle cap, requiring workers to manually wipe away the oil-based paint inside the bottle cap after the wiping process is completed. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a bottle cap surface treatment positioning mold that effectively prevents oily coatings from entering the bottle cap during processing.

[0005] To solve the aforementioned technical problems, this utility model provides the following technical solution: a bottle cap surface treatment positioning mold, comprising a mold head whose outer wall matches the inner wall of the bottle cap, and a connecting part with an outer diameter smaller than the mold head and connected to the bottom of the mold head. A step is formed between the connecting part and the mold head, and after the bottle cap is fitted into the mold head, the opening side is lower than or flush with the bottom surface of the mold head. During the processing of this bottle cap surface treatment positioning mold, oil-based paint will not enter the bottle cap, and a polishing cloth wheel can wipe the opening end face of the bottle cap. After processing, there will be no oil-based paint residue inside the bottle cap, effectively improving processing efficiency.

[0006] In the above technical solution, preferably, both the connecting part and the mold head are cylindrical, and the connecting part is concentrically connected to the bottom of the mold head.

[0007] In the above technical solution, preferably, the mold head and the connecting part are integrally formed.

[0008] In the above technical solution, preferably, the die head includes an upper die head and a lower die head. The upper die head is integrally formed with the connecting part, and the connecting part is provided with external threads. The lower die head is threadedly screwed onto the connecting part. This structure allows for height adjustment by rotating the lower die head on the connecting part, making the overall height of the die head adjustable, thus suitable for producing bottle caps of the same diameter but different heights.

[0009] In the above technical solution, preferably, the die head further includes a replaceable pad fitted on the connecting part between the upper die head and the lower die head. Since the polishing roller contacts the lower die head when wiping the opening face of the bottle cap, the lower die head may tend to rotate, or may rotate at all. By setting the pad, the lower die head cannot rotate upwards. By setting the direction of the polishing roller, the tendency of the lower die head to rotate is made upwards, thus ensuring the high stability of the die head formed by the upper die head, the pad, and the lower die head during production. When processing bottle caps with the same diameter but different heights, pads of different heights can be replaced to adapt to bottle caps of different heights. At the same time, the pad avoids a hollow space between the upper and lower die heads, preventing the polishing roller from bending the bottle cap when wiping its outer wall.

[0010] Compared with the prior art, this utility model has the following advantages: during the processing of this bottle cap surface treatment positioning mold, oily paint will not enter the bottle cap, and the polishing cloth wheel can wipe the opening end face of the bottle cap. After processing, there will be no oily paint residue inside the bottle cap, which effectively improves processing efficiency. Attached Figure Description

[0011] Figure 1 This is a cross-sectional structural diagram of Embodiment 1 of the present invention.

[0012] Figure 2 This is a cross-sectional structural diagram of Embodiment 2 of the present invention.

[0013] Figure 3 This is a cross-sectional structural diagram of the background technology of this utility model. Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figure 1 Example 1: A bottle cap surface treatment positioning mold includes a mold head 1 whose outer wall matches the inner wall of a bottle cap 3, and a connecting part 2 with an outer diameter smaller than the mold head 1 connected to the bottom of the mold head 1. A step is formed between the connecting part 2 and the mold head 1. After the bottle cap 3 is fitted into the mold head 1, the opening side is lower than or flush with the bottom surface of the mold head 1. During the processing of this bottle cap surface treatment positioning mold, oily paint will not enter the bottle cap 3, and the polishing cloth wheel can wipe the opening end face of the bottle cap 3. After processing, there will be no oily paint residue inside the bottle cap 3, effectively improving processing efficiency.

[0015] In this embodiment, both the connecting part 2 and the mold head 1 are cylindrical, and the connecting part 2 is concentrically connected to the bottom of the mold head 1.

[0016] In this embodiment, the mold head 1 and the connecting part 2 are integrally formed.

[0017] See Figure 2 Example 2: A positioning mold for bottle cap surface treatment. The difference between Example 2 and Example 1 is that the mold head 1 includes an upper mold head 11 and a lower mold head 12. The upper mold head 11 is integrally formed with the connecting part 2, and the connecting part 2 is provided with external threads. The lower mold head 12 is threadedly screwed onto the connecting part 2. Using this structure, the height of the mold head 1 can be adjusted by rotating the lower mold head 12 on the connecting part 2, making the overall height of the mold head 1 adjustable, thus suitable for the production of bottle caps 3 with the same diameter but different heights.

[0018] In this embodiment, the die head 1 also includes a replaceable pad 13 fitted onto the connecting part 2 between the upper die head 11 and the lower die head 12. Since the polishing roller contacts the lower die head 12 when wiping the opening end face of the bottle cap 3, the lower die head 12 may tend to rotate, or may rotate at all. By setting the pad 13, the lower die head 12 is prevented from rotating upwards. By setting the direction of the polishing roller, the tendency of the lower die head 12 to rotate is made upwards, thereby ensuring that the die head 1, formed by the upper die head 11, the pad 13, and the lower die head 12, is highly stable during production. When processing bottle caps with the same diameter but different heights, pads of different heights can be replaced to adapt to bottle caps of different heights. At the same time, the pad 13 prevents a hollow space between the upper die head 11 and the lower die head 12, preventing the polishing roller from bending the bottle cap 3 when wiping its outer wall.

[0019] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
