Description

Technical Field

[0001] This utility model relates to the field of zipper production technology, specifically to an integrated zipper template. Background Technology

[0002] Traditional zipper manufacturing typically employs separate injection molding or metal stamping to produce the zipper teeth, which are then fixed to the zipper tape via sewing or riveting. This production method suffers from complex processes, low efficiency, and high costs, and the resulting zipper teeth exhibit poor consistency, making them prone to deformation or breakage due to stress concentration. While existing one-piece molding technology simplifies the process to some extent, it still suffers from defects such as uneven material injection, insufficient cavity filling, and difficulty in demolding, affecting the zipper's molding quality and mechanical properties. Furthermore, traditional molds lack effective positioning and stress dispersion designs, resulting in low assembly accuracy and short service life, making it difficult to meet the manufacturing requirements of high-performance zippers.

[0003] Therefore, there is an urgent need for an integrated zipper template that can achieve efficient injection molding, improve the quality of zipper teeth molding, enhance the stability of the mold structure, and facilitate assembly and positioning. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated zipper template to overcome the shortcomings of the above-mentioned technology.

[0005] To achieve the above objectives, this utility model provides an integrated zipper template, including a base plate module, an injection module, a stress dispersion module, and a positioning assembly module;

[0006] The base plate module is a supporting base plate. The top surface of the supporting base plate is provided with a matrix-arranged zipper tooth forming cavity group. The zipper tooth forming cavity group includes several evenly distributed single zipper tooth cavities and fabric cavities. The inner wall of each single zipper tooth cavity is provided with a micro-protrusion structure to enhance the adhesion of the zipper tooth material during filling and to improve the zipper demolding quality. The fabric cavity is connected to the single zipper tooth cavity. The bottom surface of the supporting base plate is provided with mounting holes.

[0007] The injection module includes an injection plate located above the supporting base plate. The injection plate has an internal injection channel connected to the chain tooth forming cavity assembly. The injection channel has a tree-like branching structure, including a main channel and multiple secondary branch channels. The end of each secondary branch channel is connected to a single chain tooth cavity. The top surface of the injection plate also has an injection port connected to the main channel. A lifting connector is provided at the top of the injection plate.

[0008] The stress dispersion module is embedded inside the bearing base plate and includes multiple cross-distributed reinforcing ribs, which are interconnected to form a grid-like support structure.

[0009] The positioning assembly module includes multiple positioning holes on the top surface of the supporting base plate and multiple assembly protrusions on the bottom surface of the injection plate.

[0010] Preferably, the position of the mounting protrusion corresponds to the positioning hole, and the outer diameter of the mounting protrusion is smaller than the inner diameter of the positioning hole.

[0011] Preferably, the injection port has a funnel-shaped flared structure.

[0012] Preferably, the depth of the positioning hole is 1 / 3 of the thickness of the bearing base plate.

[0013] The beneficial effects of this utility model are: 1. By using a matrix arrangement of chain tooth forming cavities and a tree-like branch-shaped injection channel, the molten material is evenly distributed, reducing material shortages or air bubbles, and improving the shape consistency and mechanical properties of the chain teeth.

[0014] 2. The built-in stress dispersion module effectively disperses the internal stress during the injection molding process through the grid-like reinforcing rib structure, preventing substrate deformation or cracking and extending the service life of the mold.

[0015] 3. The tree-like branched injection channel design optimizes the material flow path, and the funnel-shaped injection port facilitates injection and reduces overflow, further improving production efficiency and yield.

[0016] 4. The positioning holes and assembly protrusions enable rapid and accurate alignment of the injection module and the base plate module, reducing assembly errors and improving production speed and mold reusability. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] Reference Figure 1-5 This embodiment provides an integrally molded zipper template, including a base plate module, an injection module, a stress dispersion module, and a positioning assembly module;

[0026] The substrate module is a support base plate 1. The top surface of the support base plate 1 is provided with a matrix arrangement of chain tooth forming cavities. The chain tooth forming cavity group includes several evenly distributed chain tooth single cavities 2 and fabric cavities 3. The inner wall of each chain tooth single cavity 2 is provided with a micro protrusion structure 4 to enhance the adhesion of the chain tooth material during filling and to improve the demolding quality of the zipper. The fabric cavity 3 is connected to the chain tooth single cavity 2. The bottom surface of the support base plate 1 is provided with mounting holes 5.

[0027] The injection module includes an injection plate 6, which is located above the supporting base plate 1. The injection plate 6 has an injection channel inside that communicates with the chain tooth forming cavity assembly. The injection channel has a tree-like branch structure and includes a main channel 7 and multiple secondary branch channels 8. The end of each secondary branch channel 8 is connected to a chain tooth single cavity 2. The top surface of the injection plate 6 is also provided with an injection port 9 that communicates with the main channel. The top of the injection plate 6 is provided with a lifting connector 10.

[0028] The stress dispersion module is embedded inside the bearing base plate 1 and includes multiple cross-distributed reinforcing ribs 11, which are interconnected to form a grid-like support structure.

[0029] The positioning assembly module includes multiple positioning holes 12 on the top surface of the supporting base plate 1 and multiple assembly protrusions 13 on the bottom surface of the injection plate 6.

[0030] The position of the mounting protrusion 13 corresponds to the positioning hole 12, and the outer diameter of the mounting protrusion 13 is smaller than the inner diameter of the positioning hole 12.

[0031] Injection port 9 has a funnel-shaped flared structure.

[0032] The depth of the positioning hole 12 is 1 / 3 of the thickness of the supporting base plate 1.

[0033] When the one-piece molded zipper template is in operation, the zipper fabric is first placed in the fabric cavity 3. The injection module and the base plate module are precisely aligned and assembled through the positioning assembly module. The fabric is pressed and fixed, and the injection channel is connected to the zipper tooth forming cavity group. The molten material is injected from the injection port 9 and evenly distributed to each zipper tooth cavity 2 through the main channel 7 and the secondary distribution channel 8. During the injection process, the grid-like reinforcing ribs 11 of the stress dispersion module effectively absorb and disperse the injection pressure to prevent the base plate module from deforming.

[0034] After the material cools and solidifies, the micro-protrusion structure 4 in the single cavity 2 of the chain tooth helps to separate the formed chain tooth from the cavity. Finally, the injection module is separated from the base plate module by the lifting connector 10, and the chain tooth is demolded by the fabric edge. Throughout the process, the tree-like branch structure of the injection channel ensures the uniformity of injection, and the positioning assembly module ensures the repeatability accuracy for multiple uses, thereby achieving efficient and high-precision integrated zipper chain tooth forming.

[0035] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
