Description

Technical Field

[0001] This utility model relates to the field of bag manufacturing, and more specifically, to an automatic zipper shaping mold. Background Technology

[0002] A zipper consists of zipper teeth and fabric straps on both sides. During the production and processing of leather bags, the fabric straps on both sides of the zipper are sewn to the opening of the bag. The existing bag opening is U-shaped, and the corresponding zipper must also be U-shaped. Because zippers are flexible, it is difficult to control the position when sewing the zipper to the bag opening. The operation is extremely time-consuming and it is easy to cause the fabric straps on both sides to be misaligned with the bag opening, resulting in rework or even scrap. In order to quickly sew the zipper to the bag opening, it is necessary to pre-shape the zipper so that it is U-shaped before sewing. Therefore, there is an urgent need for a mold that can shape the zipper into a U-shape. Utility Model Content

[0003] This invention provides an automatic zipper shaping mold, which aims to solve the problem of how to shape zippers into a U-shape.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic zipper shaping mold, comprising a driving cylinder, a U-shaped base and a pressure block, wherein the pressure block is inserted into the base, the base has two cavities at two corners, and a slider is slidably disposed in the cavity, the piston rod of the driving cylinder is connected to the slider, a first sliding plate and a second sliding plate are installed on the two end faces of the slider, and movable limiting blocks are provided on both sides of the base near the opening.

[0005] Furthermore, the base groove has built-in slots on both sides, and springs and clearance blocks are installed in the built-in slots.

[0006] Furthermore, the base has sliding grooves on both sides of the opening, the limiting block is slidably placed in the sliding groove, and handles are provided on both outer sides of the base. The handles are hinged to the sliding shaft, and the end of the sliding shaft is connected to the limiting block.

[0007] Furthermore, the first slide has a notch, and the second slide has an extension. When the first slide and the second slide move closer or apart, the extension is inserted into or removed from the notch.

[0008] Furthermore, a fixing groove is provided on the inner side of the base.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model discloses an automatic zipper shaping mold with a simple and ingenious design. It includes a drive cylinder, a U-shaped base, and a pressure block. The pressure block is inserted into the base, which has two cavities at its two corners. Sliding blocks are slidably mounted within these cavities. The piston rod of the drive cylinder connects to the sliding blocks. A first sliding plate and a second sliding plate are mounted on the two ends of the sliding blocks. Movable limiting blocks are positioned on both sides of the base near the openings. In use, the pressure block first presses the zipper teeth against the inner wall of the base's groove. The limiting blocks extend to both sides of the base's groove to block the pressure block. Then, the drive cylinder pushes the sliding blocks, causing the first and second sliding plates on both ends to move towards the center of the base, folding the fabric strips on both sides of the zipper. Finally, the entire base is heated and shaped on both sides. After shaping, the limiting blocks are moved to remove the pressure block, achieving a U-shaped zipper shaping. The cooperation between the pressure block and the base groove enables rapid positioning, making operation simple and convenient, and improving practicality. Attached Figure Description

[0022] Example

[0023] Reference Figure 1-5As shown, this utility model discloses an automatic zipper shaping mold, including a drive cylinder 107, a U-shaped base 10, and a pressure block 20. The pressure block 20 is inserted into the base 10. Specifically, a fixing groove is opened on the inner side of the base 10. When the zipper teeth are aligned with the fixing groove, the pressure block 20 is pushed into the groove of the base 10 to press the zipper into the fixing groove of the base 10, making the zipper U-shaped. Further, there are built-in grooves on both sides of the groove of the base 10. Springs and avoidance blocks 106 are set in the built-in grooves. When the zipper is placed in the groove of the base 10, the zipper pull faces the avoidance block 106. When the pressure block 20 is inserted into the groove of the base 10, the side of the pressure block 20 will push the pull head against the avoidance block 106. The avoidance block 106 compresses the spring, that is, the zipper pull is placed in the built-in groove, which plays the role of storing the zipper pull and making the insertion of the pressure block 20 into the groove of the base 10 smoother.

[0024] Reference Figure 1-5 As shown, movable limiting blocks 104 are provided on both sides of the base 10 near the opening. Specifically, the base 10 has sliding grooves on both sides of the opening, and the limiting blocks 104 are slidably placed in the sliding grooves. Handles 105 are provided on both outer sides of the base 10. The handles 105 are hinged to sliding shafts, and the ends of the sliding shafts are connected to the limiting blocks 104. When the pressure block 20 enters or exits the groove of the base 10, the handles 105 are manually pushed to drive the limiting blocks 104 to extend out of the sliding grooves and lock onto the end face of the pressure block 20 to prevent the pressure block 20 from falling out of the groove of the base 10.

[0025] Reference Figure 1-5 As shown, the base 10 has two cavities at its two corners. A slider 101 is slidably mounted in each cavity. The piston rod of the drive cylinder 107 is connected to the slider 101. A first sliding plate 102 and a second sliding plate 103 are mounted on both ends of the slider 101. Specifically, when the pressure block 20 presses the zipper teeth into the groove of the base 10, the fabric strips on both sides of the zipper extend out from the groove of the base 10. The drive cylinder 107 is controlled to push the slider 101 to move the first sliding plate 102 and the second sliding plate 103 toward the center of the base 10, folding the fabric strips on both sides of the zipper. Finally, the overall mold is preheated and shaped to complete the positioning of the zipper.

[0026] Furthermore, the first slide plate 102 has a notch 1021, and the second slide plate 103 has an extension 1031. When the first slide plate 102 and the second slide plate 103 move closer or apart, the extension 1031 is inserted into or removed from the notch 1021. When the two drive cylinders 107 retract their piston rods, they move the first slide plate 102 and the second slide plate 103 on the same end face of the base 10 toward the side closer to the drive cylinder 107, and the extension 1031 separates from the notch 1021. When the drive cylinder 107 pushes the first slide plate 102 and the second slide plate 103 toward the center of the base 10, the first slide plate 102 and the second slide plate 103 come together and fit together, and the extension 1031 inserts into the notch 1021 to form a U-shaped plate in the same direction as the groove of the base 10, which can fold the fabric strips on both sides of the zipper.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
