A tooling structure for solving cracks in products with buckle sealing strips

Abstract

The present application discloses a tooling structure for solving the problem of cracks in products with snap-on sealing strips, including: a core for molding products with snap-on sealing strips, which is half mounted in an upper template and a lower template. There are also upper templates and lower templates, wherein half of the core is installed in the upper template, and the other half of the core is installed in the upper template. The core, the upper template, and the lower template form a cavity for molding products with snap-on sealing strips. When molding products with snap-on sealing strips in the upper template or lower template area, the large end is above and below the large end and does not exceed two sides, thereby avoiding the situation where the products with snap-on sealing strips contact the upper template on three sides to produce strong adsorption. When demolding, the upper template, the lower template and the core of the products with snap-on sealing strips are separated first, and then the products with snap-on sealing strips are separated from the core, thereby solving the problem that cracks are easily formed when the products with snap-on sealing strips need to be buckled off from the upper template with tools.

Description

Technical Field

[0001] The utility model relates to a tooling structure for solving cracks in products such as sealing strips with buckles, and belongs to the technical field of tooling for producing sealing strips. Background Art

[0002] When the buckle seal strip products are produced by tooling, the core 2 of the existing tooling is clamped in the lower template 3. When demolding, the lower template 3 is separated from the upper template 1 with the core 2. Since the buckle seal strip products 4 are in contact with the upper template 1 on three sides to generate strong adsorption, the buckle seal strip products 4 will be stuck in the upper template 1, such as Figure 5 When the buckle sealing strip product 4 is buckled off from the upper template 1 by a tool later, the buckle sealing strip product 4 may easily have cracks. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a tooling structure for solving cracks in products with snap-on sealing strips.

[0004] The utility model is realized through the following technical solutions.

[0005] The utility model provides a tooling structure for solving cracks in products with buckle sealing strips, comprising:

[0006] Products with snap-on sealing strips are molded in half on the core of the upper and lower templates.

[0007] It also includes an upper template and a lower template. Half of the core is installed in the upper template, and the other half of the core is installed in the upper template. The core, the upper template and the lower template form a cavity for molding products with snap-on sealing strips.

[0008] The upper template is provided with a positioning hole A for positioning and installing the upper half of the large end of the core.

[0009] The lower template is provided with a positioning hole B for positioning and installing the upper half of the large end of the core.

[0010] It also includes products with snap-on sealing strips, wherein the upper and lower ends of the products with snap-on sealing strips correspond to the upper and lower templates.

[0011] The upper template and the lower template are fixedly connected with a handle for operating the upper template and the lower template to close or separate the molds.

[0012] The upper template and the lower template are positioned and matched by positioning pins.

[0013] There are four positioning pins corresponding to the four corners of the upper template and the lower template.

[0014] The beneficial effect of the utility model is that when the products with snap-on sealing strips are formed in the upper template or lower template area, the large end is above and the large end is below and does not exceed two sides, thereby avoiding the situation where the three sides of the products with snap-on sealing strips contact the upper template to produce strong adsorption. When demolding, the upper template, the lower template and the core of the products with snap-on sealing strips are separated first, and then the products with snap-on sealing strips are separated from the core, thus solving the problem that cracks are easy to occur when tools are needed to buckle the products with snap-on sealing strips from the upper template.

[0021] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0022] like Figures 1 to 3 shown.

[0023] The present application discloses a tooling structure for solving cracks in products with buckle sealing strips, including:

[0024] The core 2 is installed in half in the upper template 1 and the lower template 3. The upper template 1 is provided with a positioning hole A11 for positioning and installing the upper half of the large end of the core 2; the lower template 3 is provided with a positioning hole B21 for positioning and installing the upper half of the large end of the core 2. Half of the core 2 is installed in the upper template 1, and the other half of the core 2 is installed in the upper template 1. The core 2, the upper template 1, and the lower template 3 form a cavity for molding a product 4 with a buckle seal strip. The cavity does not exceed two sides in the upper template 1 or the lower template 3 area, so that the upper 41 and the lower 42 of the large end of the product 4 with a buckle seal strip after molding correspond to the upper template 1 and the lower template 3.

[0025] The upper mold plate 1 and the lower mold plate 3 are fixedly connected with a handle 6, and the upper mold plate 1 and the lower mold plate 3 are closed or separated by the handle 6.

[0026] The upper template 1 and the lower template 3 are positioned and matched at four corners by four positioning pins 5 .

[0027] When the snap-in sealing strip product 4 forms a cavity with the core 2 and the upper template 1 and the lower template 3, the snap-in sealing strip product 4 is not more than two sides in the upper template 1 or the lower template 3, and the upper side 41 of the large end and the lower side 42 of the large end of the snap-in sealing strip product 4 correspond to the upper template 1 and the lower template 3, thereby avoiding the situation that the snap-in sealing strip product 4 contacts the upper template 1 on three sides to produce strong adsorption. When demolding, the upper template 1 and the lower template 3 are separated from the core 2 with the snap-in sealing strip product 4 first, and then the snap-in sealing strip product 4 is separated from the core 2, thereby solving the problem that the snap-in sealing strip product 4 is prone to cracks when it is necessary to use tools to buckle it off from the upper template 1.
