Abstract
Description
Technical Field
[0001] This invention relates to a universal, low-cost, springless material ejection and flattening mold, belonging to the field of mold technology. Background Technology
[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the object's shape by changing the physical state of the material being molded. Copper braided wire, often called the "mother of industry," plays an important role in many fields due to its excellent conductivity, flexibility, and corrosion resistance, especially with the continuous development of the new energy industry. The pressing of copper braided wire and copper tubes of various specifications is increasing, and flattening molds are needed when processing copper braided wire and copper tubes.
[0003] Existing flattening dies suffer from a severe "one-to-one" adaptation limitation. Products of different widths and thicknesses require individually designed and manufactured flattening dies of corresponding dimensions. This forces companies to repeatedly invest significant funds in the development and production of flattening dies when facing the production needs of multiple product specifications. This not only significantly increases upfront equipment procurement costs but also incurs high additional costs for mold storage, management, and maintenance due to the wide variety of mold types, significantly increasing the burden on production and operations. Furthermore, the dies suffer from insufficient structural strength and limited adaptability. For example, flattening dies using spring unloading structures require a substantial increase in unloading force when processing narrow and thick special-specification products. This increase necessitates replacing the springs with larger ones and expanding the spring clearance space inside the mold. This adjustment directly weakens the effective load-bearing structure of the mold body, reducing its overall strength. During long-term high-pressure stamping operations, this can easily lead to deformation, cracking, and other malfunctions, shortening the mold's lifespan and limiting its stable processing capability for narrow and thick special-specification products.
[0004] To address this, a universal, low-cost, spring-free material flattening mold is proposed. Summary of the Invention
[0005] In view of this, the present invention provides a universal, low-cost, springless stripping and flattening mold to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.
[0006] The technical solution of the present invention is implemented as follows: a universal low-cost springless flattening mold includes an upper template and a lower template. The top of the lower template is provided with a tension block, a pad block, and a replaceable pad block. The top of the pad block is provided with a replaceable stop block. The bottom of the upper template is provided with an upper mold groove plate. The surface of the upper mold groove plate is connected to front and rear stop blocks by bolts and threads. The surfaces of the front and rear stop blocks are engaged with replaceable pressing blocks. The top of the replaceable pad block is where the product to be pressed is placed.
[0007] More preferably, the surface of the lower template is threaded with a lower hexagonal socket screw, and the top of the lower hexagonal socket screw is threaded to the inner surface of the pad.
[0008] More preferably, the surface of the tensioning block is threaded with a plug screw, which is threaded onto the inner surface of the pad block.
[0009] More preferably, the top of the upper template is threaded with an upper hexagonal screw, and the bottom of the upper hexagonal screw is threaded to the inner surface of the upper mold groove plate.
[0010] More preferably, the adjustment component includes a replaceable stop block, a replaceable pressure block, and a replaceable pad block. The replaceable stop block and the replaceable pad block cooperate to limit the lateral displacement of the product. The replaceable stop block, the replaceable pressure block, and the replaceable pad block are all designed to be "replaceable" and are connected to corresponding positions through V-grooves. They can be flexibly replaced according to different product sizes. A floating gap is reserved between the tension block and the replaceable pad block for fine-tuning the position during loading and width maintenance.
[0011] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:
[0012] I. This invention features replaceable pressure blocks, replaceable pads, and replaceable stops, all of which are detachable structures. Simply replacing the corresponding parts allows for adaptation to products of different sizes, improving the mold's versatility. Simultaneously, the width difference between the held-width and open-width states allows for product relaxation, solving the problem of traditional molds requiring spring unloading. The replaceable pressure blocks, pads, and stops are all detachable structures, enabling quick-change structures and allowing a single mold to adapt to multiple product specifications. This saves 80% on new mold development costs, reduces overall mold operating costs by 50%, and mold changes take only five minutes, increasing production efficiency by 40%. The spring-free design preserves the mold's complete load-bearing structure, increasing strength by 60% and extending lifespan by two to three times. It can stably process narrow and thick special products, and mechanical unloading is unaffected by environmental conditions or spring aging, achieving an unloading success rate of over 99.9%, eliminating the risk of jamming and product damage. Standardized components and simplified structure reduce maintenance frequency and difficulty.
[0013] Second, by setting the lower hexagonal screw, the present invention can facilitate the disassembly and assembly of the lower template and the pad, thus improving the convenience of mold assembly. By setting the plug screw, the connection between the tension block and the pad can be realized, which improves the convenience of disassembly and assembly between the two. By setting the upper hexagonal screw, the connection between the upper template and the upper mold groove plate can be realized, which facilitates the assembly of the two.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0022] Example 1
[0023] like Figure 1-3As shown, this embodiment of the invention provides a universal, low-cost, springless flattening mold, including an upper template 7 and a lower template 1. The top of the lower template 1 is provided with a tensioning block 2, a pad block 10, and a replaceable pad block 3. Each pad block 10 has a replaceable stop block 4 on its top. The bottom of the upper template 7 is provided with an upper mold groove plate 6. Front and rear stop blocks 12 are connected to the surface of the upper mold groove plate 6 by bolts and threads. Replaceable pressure blocks 5 are engaged with the surfaces of the front and rear stop blocks 12. The product to be pressed 11 is placed on top of the replaceable pad block 3. The adjustment assembly includes the replaceable stop block 4, the replaceable pressure block 5, and the replaceable pad block 3. The replaceable stop block 4 cooperates with the replaceable pad block 3 to restrict the lateral displacement of the product to be pressed 11. All three components—the replaceable stop block 4, the replaceable pressure block 5, and the replaceable pad block 3—are replaceable. The design allows for flexible replacement of different product sizes by connecting to the corresponding positions via V-grooves. A floating gap is reserved between the tension block 2 and the replaceable pad block 3 for fine-tuning the position during loading and width maintenance.
[0024] The replaceable pressure block 5, replaceable pad block 3, and replaceable stop block 4 are all detachable structures. Simply replacing the corresponding parts allows for adaptation to products of different sizes, improving the mold's versatility. Simultaneously, the width difference between the held-width and open-width states allows for product relaxation, solving the problem of traditional molds requiring spring unloading. The replaceable pressure block, replaceable pad block, and replaceable stop block are all detachable structures, allowing for adaptation to products of different sizes by simply replacing the corresponding parts. This saves 80% on new mold development costs, reduces overall mold operating costs by 50%, and mold changes take only five minutes, increasing production efficiency by 40%. The springless design preserves the mold's complete load-bearing structure, increasing strength by 60% and extending lifespan by two to three times. It can stably process narrow and thick special products, and mechanical unloading is unaffected by environmental conditions or spring aging, achieving an unloading success rate of over 99.9%, eliminating the risk of jamming and product damage. Standardized components and simplified structure reduce maintenance frequency and difficulty.
[0025] Example 2
[0026] like Figure 2-3 As shown, in one embodiment, the surface of the lower template 1 is threaded with a lower hexagonal screw 8, the top of the lower hexagonal screw 8 is threaded to the inner surface of the pad 10, the surface of the tension block 2 is threaded with a stop screw 9, the stop screw 9 is threaded to the inner surface of the pad 10, the top of the upper template 7 is threaded with an upper hexagonal screw 13, the bottom of the upper hexagonal screw 13 is threaded to the inner surface of the upper mold groove plate 6.
[0027] By setting the lower hex screw 8, the lower template 1 and the pad 10 can be easily disassembled and assembled, which improves the convenience of mold assembly. By setting the plug screw 9, the tension block 2 and the pad 10 can be connected, which improves the convenience of disassembly and assembly between the two. By setting the upper hex screw 13, the upper template 7 and the upper mold groove plate 6 can be connected, which facilitates the assembly of the two.
[0028] When this invention is in operation: the mold completes the product forming process by switching between three states: "open - width retention - closed". The specific process is as follows:
[0029] On status
[0030] The upper mold assembly is lifted upwards, and the replaceable pad 3 and tension block 2 of the lower mold assembly are in a relaxed state. At this time, the product to be formed 11 can be placed into the positioning area surrounded by the replaceable pad 3 and replaceable stop block 4 of the lower mold to complete the loading.
[0031] Maintain width status
[0032] When the upper mold assembly moves downward and does not fully close, the replaceable pressure block 5 initially contacts the product 11 to be pressed. At the same time, the position of the tension block 2 is adjusted by the upper mold groove plate 6 to achieve precise positioning of the product and "width protection", that is, to ensure the dimensional accuracy of the width direction of the product molding.
[0033] Closed state
[0034] The upper mold assembly continues to move downwards, and the upper mold groove plate 6 and the tension block 2 are completely in contact. The replaceable pressure block 5 completely presses the product 11 to be pressed. At this time, the various parts of the mold form a closed cavity, and the product molding and mold closing are completed.
[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
