Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper processing, specifically to a quick-change device for zipper shaping molds. Background Technology
[0002] A zipper is a connecting device that uses continuously arranged teeth to open and close items. It is widely used in clothing, bags, shoes and other fields. Its core components include teeth, zipper pull, fabric tape and top and bottom stops. Zipper processing refers to the complete manufacturing process of turning raw materials into finished zippers, covering design, mold making, injection molding / die casting, assembly, and testing.
[0003] In the existing technology, zipper shaping adopts traditional processes, which require a pre-processed mold plate. The mold plate is made by precision machining and heat treatment according to the zipper design specifications, with high dimensional accuracy. During production, the selected plastic raw material (such as nylon or polyester) is heated and melted, and then injected into the mold plate cavity with a certain pressure and speed using injection molding equipment. After cooling and solidification, the finished zipper part that meets the requirements is formed.
[0004] After long-term use, zipper forming molds are usually integral structures. After long-term use, the surface wears down and the whole mold needs to be replaced. Traditional mold fixing methods rely on screw tightening or manual pressing. Disassembly requires professional tools and technicians, which is time-consuming and costly. Utility Model Content
[0005] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a quick-change device for zipper shaping molds. Through two separate installation structures, the mold placement slot and mold components can be replaced separately, reducing the cost required for mold replacement. By using separate installation and two threaded connectors to limit the mold components, stable installation of the mold is achieved with fewer installation and fixing structures, thus improving the stability of use.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A quick-change device for zipper shaping molds includes a placement platform; it also includes a mold placement slot, a flip plate, and a mold assembly. The upper end of the placement platform has two first placement slots, into which a mold placement slot is inserted. A connecting frame for quick change is placed on the mold placement slot. The connecting frame has multiple rotating mounting slots, on which the flip plate is rotatably placed. A second bolt mounting hole is formed through the flip plate. The mold assembly is mounted on the flip plate. The mold assembly includes a first connecting mold that is installed through the second bolt mounting hole using a threaded connector; first sliding grooves at the left and right ends of the first connecting mold; a second connecting mold inserted into the first sliding groove; and limiting strips connecting the left and right ends of the second connecting mold. The limiting strips and the first sliding grooves are mutually compatible. A trapezoidal platform is fixed to the upper end of the mold placement slot. A first bolt mounting hole is formed at the upper end of the trapezoidal platform. The second connecting mold is installed in the first bolt mounting hole on the trapezoidal platform using a bolt connector.
[0008] In one optional embodiment, the upper end of the first placement groove is provided with three second slots, and two first slots are provided through the first placement groove. The lower end of the mold placement groove is fixedly connected with two second limiting sleeves, and the lower end of the mold placement groove is fixedly connected with three inserts. The inserts and second slots are mutually compatible.
[0009] In one alternative embodiment, two first limiting sleeves are fixed to the lower end of the placement platform, and a second limiting sleeve extends to the lower end of the placement platform after passing through the first slot.
[0010] In one optional embodiment, two support frames are fixedly connected to the lower end of the placement platform, and a connecting platform is fixedly connected to the lower end of the two support frames. A double-headed cylinder is fixedly connected to the upper end of the connecting platform, and U-shaped connecting arms are connected to the two output ends of the double-headed cylinder. The upper end of the U-shaped connecting arm passes through the first limiting sleeve and is inserted into the second limiting sleeve.
[0011] In one optional embodiment, the upper end of the connecting frame is provided with multiple injection molding connecting grooves, and the integral structure formed by the insertion of the first connecting mold and the second connecting mold is provided with a mold groove, and the mold groove and the injection molding connecting groove are connected to each other.
[0012] In one optional embodiment, a trapezoidal block is fixed to the upper end of the first connecting mold, and the straight end of the trapezoidal block near the flipping plate and the corresponding straight end on the flipping plate are in contact with each other.
[0013] In one alternative embodiment, a first groove is provided at the end of the second connecting mold away from the flipping plate, and the shapes of the first groove and the trapezoidal platform are complementary.
[0014] In one alternative implementation, the upper end of the flip plate is flush with the upper end of its threaded connector.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. By using two separate installation structures, the mold placement slot and mold components can be replaced separately, reducing the cost required for mold replacement. The separate installation, combined with two threaded connectors to limit the mold components, achieves stable installation of the mold with fewer installation and fixing structures, thus improving the stability of use.
[0017] 2. By setting up structures such as a double-headed cylinder, a U-shaped connecting arm, a first limiting sleeve, and a second limiting sleeve, opening the double-headed cylinder causes the two telescopic ends to move the two U-shaped connecting arms away from each other, which allows the second limiting sleeve at the lower end of the mold placement slot to be unsecured, thereby quickly removing it from the mold placement slot and improving the overall efficiency of disassembly and assembly of the mold placement slot.
[0018] 3. When replacing a mold component on the mold placement slot, first remove the threaded connector of the second connecting mold installed in the first bolt mounting hole, then flip the flip plate, push the mold component upward, and pull the second connecting mold out from the first connecting mold along the first slide groove to replace the second connecting mold; removing the threaded connector from the second bolt mounting hole on the flip plate can also remove the first connecting mold from the connecting frame, thereby completing the replacement of the mold component and realizing the rapid individual replacement of the mold component.

[0030] Please refer to Figures 1-5 This utility model provides an embodiment of a quick-change device for zipper shaping molds, including a placement platform 1; it also includes a mold placement groove 2, a flip plate 303, and a mold assembly. The upper end of the placement platform 1 has two first placement grooves 101, into which the mold placement groove 2 is inserted. A connecting frame 3 for quick replacement is placed on the mold placement groove 2. The connecting frame 3 has multiple rotating mounting grooves 301, on which the flip plate 303 is rotatably placed. A second bolt mounting hole 304 is provided through the flip plate 303. A mold assembly is mounted on the flip plate 303. The mold assembly includes a first connecting mold 4 installed by a threaded connector passing through the second bolt mounting hole 304, first sliding grooves 402 at the left and right ends of the first connecting mold 4, and more. The second connecting mold 403 is inserted into the first slide groove 402, and the limiting strips 404 are connected to the left and right ends of the second connecting mold 403. The limiting strips 404 and the first slide groove 402 are mutually compatible. The upper end of the mold placement groove 2 is fixedly connected to a trapezoidal platform 201. The upper end of the trapezoidal platform 201 is provided with a first bolt mounting hole 202. The second connecting mold 403 is installed in the first bolt mounting hole 202 on the trapezoidal platform 201 through bolt connectors. By setting a split-type disassembly and assembly structure that can be threaded on the mold assembly, the damaged mold can be replaced individually. It is fixed by rotation and two threaded connectors, which limits the range of mold movement and reduces the cumbersome installation operation of mold fixing. It solves the problem that molds are usually integral structures, and when the mold is damaged, it is easy to have to replace the whole plate, which is costly.
[0031] Please refer to Figures 1-3In a preferred embodiment of this utility model, three second slots 105 are provided at the upper end of the first placement groove 101, and two first slots 104 are provided through the first placement groove 101. Two second limiting sleeves 203 are fixedly connected to the lower end of the mold placement groove 2, and three inserts 204 are fixedly connected to the lower end of the mold placement groove 2. The inserts 204 and the second slots 105 are mutually adapted. Two first limiting sleeves 106 are fixedly connected to the lower end of the placement platform 1. The second limiting sleeves 203 extend to the lower end of the placement platform 1 after passing through the first slots 104. Two support frames 1 are fixedly connected to the lower end of the placement platform 1. 02. The lower ends of the two support frames 102 are fixedly connected to a connecting platform 103. The upper end of the connecting platform 103 is fixedly connected to a double-headed cylinder 107. The two output ends of the double-headed cylinder 107 are connected to U-shaped connecting arms 108. The upper end of the U-shaped connecting arm 108 passes through the first limiting sleeve 106 and is inserted into the second limiting sleeve 203. The first limiting sleeve 106 can limit the sliding trajectory of the U-shaped connecting arm 108. The U-shaped connecting arm 108 is inserted into the second limiting sleeve 203. The double-headed cylinder 107 can control whether the mold placement groove 2 is fixed in the first placement groove 101.
[0032] Please refer to Figures 3-6 In a preferred embodiment of this utility model, the upper end of the connecting frame 3 is provided with multiple injection molding connection slots 302. The integrated structure formed by the insertion of the first connecting mold 4 and the second connecting mold 403 is provided with a mold groove. The mold groove and the injection molding connection slots 302 are connected to each other. After injection molding is completed, two adjacent injection molded parts can be connected through the injection molding connection slots 302, which facilitates subsequent removal. A trapezoidal block 401 is fixedly connected to the upper end of the first connecting mold 4. The straight end of the trapezoidal block 401 near the flip plate 303 and the corresponding straight end on the flip plate 303 are in contact with each other. The second connecting mold 403 has a first groove 405 at the end away from the flip plate 303. The shape of the first groove 405 and the trapezoidal platform 201 are complementary. The upper end of the flip plate 303 is flush with the upper end of its threaded connector. The inclined ends of the first groove 405 and the trapezoidal platform 201 fit together to improve the installation of the threaded connector in the first bolt mounting hole 202. When the flip plate 303 is not rotating, an upper limit strip 404 can be inserted into the first sliding groove 402 to restrict the sliding direction of the second connecting mold 403, thereby preventing the second connecting mold 403 from sliding out.
[0033] Two types of disassembly and assembly methods are provided for the main body of the device. First, when it is necessary to disassemble and assemble the mold placement slot 2, the double-headed cylinder 107 is opened, so that the two telescopic ends of the double-headed cylinder 107 drive the two U-shaped connecting arms 108 to move away from each other, so that the second limiting sleeve 203 at the lower end of the mold placement slot 2 is no longer fastened by the U-shaped connecting arms 108, thereby quickly disassembling the mold placement slot 2.
[0034] When it is necessary to replace the mold assembly on the mold placement slot 2 individually, firstly, the threaded connector installed in the first bolt mounting hole 202 on the second connecting mold 403 is removed. Then, the flipping plate 303 is flipped over, and the mold assembly is pushed upward. Next, the second connecting mold 403 is pulled out from the first connecting mold 4 along the first slide groove 402, thereby replacing the second connecting mold 403 on the first connecting mold 4. The first connecting mold 4 is removed from the connecting frame 3 by removing the threaded connector from the second bolt mounting hole 304 on the flipping plate 303, thus replacing the mold assembly.
[0035] Through the above steps, the mold placement slot 2 and the mold assembly can be replaced separately using two separate installation structures, reducing the cost required for mold replacement. By using separate installation and two threaded connectors to limit the mold assembly, stable installation of the mold is achieved with fewer installation and fixing structures, thus improving the stability of use.
[0036] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.
[0037] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
