Description

Technical Field

[0001] This utility model relates to a head-piercing device, and more specifically to a head-piercing device for an invisible zipper strap. Background Technology

[0002] Currently available concealed zipper pull devices mainly achieve this by combining an upper and lower mold. During the pull process, an external zipper pull conveyor automatically transports the zipper pull into the lower mold. Then, the lower mold rises and joins with the upper mold to clamp and position the zipper pull. Finally, a pull clamping device holds the concealed zipper pull and passes it between the lower and upper molds, allowing the zipper pull to be pulled onto the concealed zipper pull. However, the size of the groove opened at the bottom of the existing upper mold is fixed, which limits the applicable zipper pull sizes. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a zipper pull device that can be applied to a wider range of zipper pull models and sizes.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a concealed zipper pull device, comprising an upper pull mold and a lower pull mold, wherein the lower pull mold is mounted below the upper pull mold in a lifting manner to rise and close with the upper pull mold. The upper pull mold includes an upper mold support and an upper module, the upper module being slidably mounted on the upper mold support. The lower end of the upper module has a notch, and the upper end of the lower pull mold has a stop block. When the lower pull mold rises and closes with the upper pull mold, the upper module slides on the upper mold support, causing the notch and the stop block to combine and limit the zipper pull.

[0005] As a further improvement of this utility model, a slide rail is fixed on the upper mold support, and a slider is fixed on the side of the upper module. The slider is slidably mounted on the slide rail so that the upper module can be slidably mounted on the upper mold support. A sliding cylinder is fixed on the upper mold support, and the push rod of the sliding cylinder is connected to the upper module so as to push the upper module to slide back and forth along the slide rail below the upper mold support.

[0006] As a further improvement of this utility model, the lower mold for threading the head includes a fixed mold and an adjusting mold, the fixed mold and the adjusting mold are spaced apart from each other, the abutment block is provided at the upper end of the fixed mold, the upper end of the adjusting mold is provided with a support block, and the adjusting mold and the fixed mold are arranged to be raised and lowered relative to each other, so that when the upper mold for threading the head and the lower mold for threading the head are closed, the upper end of the adjusting mold abuts against the lower side of the pull head.

[0007] As a further improvement of this utility model, the upper end of the adjusting mold is fixed with a stop plate, and the middle part of the upper side of the stop plate is provided with a groove for accommodating the pull head, so that the pull head is accommodated in the groove when the upper mold and the lower mold are closed.

[0008] As a further improvement of this utility model, the upper end of the adjustment mold is also provided with a guide ramp, one end of which extends into the groove.

[0009] As a further improvement of this utility model, a pull tab baffle is fixed to the side wall of the fixed mold by a corner plate. The pull tab baffle is located between the fixed mold and the adjusting mold to block the pull tab on the pull head.

[0010] The beneficial effects of this utility model are:

[0011] Compared to existing concealed zipper pull devices in the background art, the groove size of the existing upper mold is fixed, limiting the types of zipper pulls that can be used. In contrast, the upper module of the upper mold of this invention is slidable, combining with the stop block of the lower mold to limit the zipper pull's position. This allows for the insertion of zipper pulls of different models and specifications. Furthermore, the adjusting mold and the fixed mold of the lower mold are relatively adjustable, with various structures such as grooves and guide ramps on the adjusting mold. The adjustment mold's movement allows for further positioning of the zipper pull during insertion. The fixed mold has a pull tab baffle, effectively preventing the pull tab from swinging left and right and affecting the operation of other components. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0017] Reference Figure 1As shown, this embodiment of a concealed zipper pull device includes an upper pull mold 1 and a lower pull mold 2. The lower pull mold 2 is movably mounted below the upper pull mold 1 to rise and close with it. The upper pull mold 1 includes an upper mold support 11 and an upper module 12. The upper module 12 is slidably mounted on the upper mold support 11. The lower end of the upper module 12 has a notch, and the upper end of the lower pull mold 2 has a stop block 24. When the lower pull mold 2 rises and closes with the upper pull mold 1, the upper module 12 slides on the upper mold support 11, causing the notch and the stop block 24 to combine and limit the zipper pull. This design allows the device to adjust the space for limiting the zipper pull by sliding the upper module 12 according to the size of different zipper pulls. Compared with the upper mold with a fixed groove size in the prior art, it can accommodate more zipper pull sizes, solving the problem of limited zipper pull models.

[0018] Furthermore, refer to Figure 2 As shown, a slide rail is fixed on the upper mold support 11, and a slider is fixed on the side of the upper module 12. The slider is slidably mounted on the slide rail to allow the upper module 12 to be slidably mounted on the upper mold support 11. A sliding cylinder 13 is fixed on the upper mold support 11, and the push rod of the sliding cylinder 13 is connected to the upper module 12 to push the upper module 12 to slide back and forth along the slide rail below the upper mold support 11. Through the cooperation of the slide rail, the slider, and the sliding cylinder 13, the sliding of the upper module 12 can be controlled more accurately and conveniently, further improving the adaptability to different slider limiters and effectively solving the problem in the background art where the fixed upper mold groove restricts the applicable slider models.

[0019] Furthermore, refer to Figure 3 As shown, the lower die 2 for threading the pull head includes a fixed die 21 and an adjusting die 22, which are spaced apart from each other. The abutment block 24 is located at the upper end of the fixed die 21, and the upper end of the adjusting die 22 is provided with a support block 221. The adjusting die 22 and the fixed die 21 are vertically adjustable relative to each other, so that when the upper die 1 and the lower die 2 for threading the pull head are closed, the upper end of the adjusting die 22 abuts against the lower side of the pull head. In this way, when the die is closed, the adjusting die 22 can support and limit the pull head from below, which, in conjunction with the limiting function of the upper die 12, allows for better threading operation.

[0020] Furthermore, refer to Figure 4 As shown, a stop plate is fixed to the upper end of the adjusting mold 22. A groove for accommodating the slider is formed in the middle of the upper side of the stop plate, so that the slider is accommodated in the groove when the upper die 1 and the lower die 2 are closed. The groove further improves the positioning accuracy of the slider, making the slider more stable during the threading process and avoiding threading failure due to slider position deviation. This improves the problem in the prior art where inaccurate slider positioning affects the threading effect.

[0021] Furthermore, the upper end of the adjusting mold 22 is provided with a guide ramp, one end of which extends into the groove. The guide ramp facilitates the retraction of the zipper strap, enabling the insertion of the concealed zipper.

[0022] Furthermore, a pull tab baffle 23 is fixed to the side wall of the fixed mold 21 via a corner plate. The pull tab baffle 23 is located between the fixed mold 21 and the adjusting mold 22 to block the pull tab on the pull head. The pull tab baffle 23 can prevent the pull tab from swinging during the threading process, ensuring the smooth progress of the threading operation and solving the problem in the prior art that the threading may be affected by the displacement of the pull tab.

[0023] In summary, this concealed zipper pull device, through a series of designs including the sliding upper module 12 of the upper mold 1, the adjustable lower mold 22 of the lower mold 2, and the groove, guide ramp, and pull tab baffle 23 on the adjustable mold 22, can adapt to more zipper pull sizes and models compared to the concealed zipper pull devices in the prior art that rely solely on a fixed groove upper mold. It improves the positioning accuracy of the zipper pull and the convenience and stability of the pull operation, effectively solving problems such as limited applicable zipper pull models, inaccurate zipper pull positioning, inconvenient operation, and easy displacement of the pull tab. It demonstrates significant advancements.
