Description

A mold structure for an airtight zipper Technical Field

[0001] This utility model relates to the field of zipper manufacturing technology, and more specifically, it relates to a mold structure for an airtight zipper. Background Technology

[0002] Zippers are common items in people's lives, mainly used in clothing, shoes, hats, and various bags. Zippers are usually composed of fabric tape, chain teeth, and a zipper pull. The chain teeth are arranged continuously on the edges of two fabric tapes. By sliding the zipper pull, the chain teeth on the two fabric tapes can be engaged or disengaged, thus achieving the function of opening and closing. In order to improve the waterproof and airproof effect when sealing, airtight zippers are used as sealing components.

[0003] An airtight zipper, as the name suggests, is a zipper that is both waterproof and airtight. It forms a sealed layer through the interlocking teeth of the zipper, preventing the flow of gas and liquid inside and outside the zipper.

[0004] Our company has previously applied for a zipper processing technology and device, publication number CN119704532A. During the production process, it was found that the groove of the fabric strip and the lower template could not be aligned in real time. As a result, when the lower template moves down, it may press down on the fabric strip or cause it to shift, which will result in injection molding failures, affect the product yield, and cause economic losses. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mold structure for an airtight zipper, which can ensure that the groove and the fabric tape are always aligned, thereby improving the product yield.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold structure for an airtight zipper, comprising a lower template and a lifting component, wherein the lifting component is used to drive the lower template to move up and down, and grooves are symmetrically arranged on both sides of the lower template. A first linkage component and a second linkage component are respectively arranged at both ends of the lower template along the conveying direction of the fabric belt. The first linkage component and the second linkage component are used to rise and fall together with the lower template, so that the fabric belt is level with and aligned with the grooves.

[0007] The present invention is further configured to include a feeding mechanism and a discharging mechanism, wherein the first linkage member is disposed on the side of the lower template near the feeding mechanism, and the second linkage member is disposed on the side of the lower template near the discharging mechanism.

[0008] The present invention is further configured such that: the first linkage component includes a first lifting block, and the first lifting block is connected to the lifting component.

[0009] The present invention is further configured such that: the first linkage component includes a second lifting block, and the second lifting block is connected to the lower template.

[0010] The present invention is further configured such that: the second linkage component includes a third lifting block, the third lifting block being connected to the upper end of the lower template.

[0011] The present invention is further configured such that the third lifting block is arranged in a strip-shaped structure and is connected to the center of the lower template.

[0012] The present invention is further configured such that the width of the third lifting block is consistent with the gap between the two chain teeth.

[0013] The present invention is further configured to include an upper mold assembly, an injection molding machine, and a controller. The lower mold plate and the upper mold assembly are both mounted on the injection molding machine, and the controller is electrically connected to the injection molding machine, the upper mold assembly, and the lifting component, respectively.

[0014] In summary, the present invention has the following beneficial effects: the design of the first linkage and the second linkage can simultaneously push the two ends of the fabric belt to rise and fall when the lower template moves up and down, so that the fabric belt is always aligned with the groove and level, ensuring the stability between the lower template and the fabric belt when the lower template moves down, ensuring the stability of subsequent injection molding, and improving the yield rate of the product.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] Referring to Figures 1 to 3, in order to achieve the above objectives, the present invention provides the following technical solution: a mold structure for an airtight zipper, including a lower template 1 and a lifting component. The lifting component is used to drive the lower template 1 to move up and down. Grooves 11 are symmetrically arranged on both sides of the lower template 1. A first linkage component 2 and a second linkage component 3 are respectively arranged at both ends of the lower template 1 along the conveying direction of the fabric belt. The first linkage component 2 and the second linkage component 3 are used to rise and fall together with the lower template 1, so that the fabric belt is level with and aligned with the grooves 11.

[0021] The design of the first linkage 2 and the second linkage 3 can simultaneously push the two ends of the fabric strip to rise and fall when the lower template 1 moves up and down, so that the fabric strip is always aligned with and level with the groove 11, ensuring the stability between the lower template 1 and the fabric strip when it moves down, ensuring the stability of subsequent injection molding, and improving the yield rate of the product.

[0022] The lifting component can use existing cylinders, electric cylinders, and motor assemblies, etc. Due to the variety of choices, they will not be described in detail here.

[0023] This utility model is further configured to include a feeding mechanism 4 and a discharging mechanism 5. A first linkage 2 is disposed on the side of the lower template 1 near the feeding mechanism 4, and a second linkage 3 is disposed on the side of the lower template 1 near the discharging mechanism 5. The feeding mechanism 4 and the discharging mechanism 5 can convey the fabric belt from left to right for punching and injection molding operations in sequence.

[0024] Example 1 of the first linkage component 2: The first linkage component 2 includes a first lifting block, which is connected to the lifting component.

[0025] Embodiment 2 of the first linkage component 2: The first linkage component 2 includes a second lifting block, which is connected to the lower template 1.

[0026] The difference between the two embodiments is that the lifting block is connected to the lower template 1 or the lifting component is connected.

[0027] The lifting block can be connected to the upper surface of the lower template 1, or it can be connected to the internal lifting component through the base. Both implementations can drive one end of the cloth belt to align with the groove 11 when the lower template 1 is raised and lowered.

[0028] The present invention is further configured such that: the second linkage 3 includes a third lifting block, and the third lifting block is connected to the upper end of the lower template 1.

[0029] The third lifting block is arranged in a strip shape and is connected to the center of the lower template 1.

[0030] The width of the third lifting block is the same as the gap between the two chain teeth. This design ensures that the belt can move up and down, and also cooperates with the injection-molded chain teeth to ensure stable movement without positional deviation.

[0031] The present invention is further configured to include an upper mold assembly 6, an injection molding machine 7, and a controller 8. The lower mold plate 1 and the upper mold assembly 6 are both installed on the injection molding machine 7, and the controller 8 is electrically connected to the injection molding machine 7, the upper mold assembly 6, and the lifting component, respectively.

[0032] In summary, this structure is based on the applicant's prior application for an automatic injection molding device, and is optimized and improved upon based on the flow structure of the automatic injection molding device.
