Description

Technical Field

[0001] The present invention relates to the field of molds, and in particular to a mold based on a splicing template. Background Art

[0002] With the improvement of people's living standards, people's requirements for comfort are also getting higher and higher. Massage chairs installed in places where people gather, such as cinemas or railway stations, are very popular.

[0003] However, the electrical installation boxes of massage chairs when sitting are mostly plate-like structures with a relatively large area. Reinforcing ribs and convex hulls for connecting screws are often provided on the installation plate to improve the mechanical properties of the installation plate. However, for the installation plate with reinforcing ribs and convex hulls being reverse protrusions, during the bending process of the installation plate, there is no protective structure for the double-sided protrusions, which easily causes deformation of the protrusion structure during the stamping process, affecting the quality of the product. Moreover, for the protective structure of multiple scattered protrusions, it is difficult to achieve with a single structure. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned defects in the prior art that during the bending process of the installation plate, there is no protective structure for the double-sided protrusions, which easily causes deformation of the protrusion structure during the stamping process, affecting the quality of the product, and for the protective structure of multiple scattered protrusions, it is difficult to achieve with a single structure, and to provide a mold based on a splicing template for protecting the double-sided protrusions of the installation plate.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A mold based on a splicing template includes an upper mold base and a lower mold base. The mold further includes an upper template and a lower template. The upper template is fixed on the upper mold base. The upper module is provided with a first groove whose shape matches the protruding shape of the reinforcing rib. The lower template includes a plurality of spliced sub-modules fixed on the lower mold base. Each sub-module is provided with a protruding accommodation hole that matches the protruding shape. The distribution of the protruding accommodation holes on the lower template corresponds to the distribution of the protrusions on the installation plate.

[0007] Further, the lower template includes a first sub-template, a second sub-template, and a third sub-template. One end of the first sub-template is clamped with the second sub-template, and the other end is clamped with the third sub-template. The protruding accommodation holes are distributed on the first sub-template, the second sub-template, and the third sub-template corresponding to the distribution of the protrusions on the installation plate.

[0008] Further, both the second sub-template and the third sub-template are provided with connecting blocks in a trapezoidal structure. The first sub-template is provided with a card slot at the corresponding position that matches the connecting block, and the connecting block is clamped in the card slot.

[0009] Further, the lower template further includes a lower die pressing block. A pressing block hole matching the shape of the lower die pressing block is provided on the first sub-template. The lower die pressing block is located in the pressing block hole and fixed on the lower die base.

[0010] Further, the lower template further includes a fourth sub-template. A notch base matching the internal bending structure on the mounting plate is provided on the fourth sub-template. The fourth sub-template is snap-connected to one end of the first sub-template.

[0011] Further, a connecting end head with a T-shaped structure is provided on the fourth sub-template. A limiting groove matching the shape of the connecting end head is provided on the first sub-template. The connecting end head is located in the limiting groove.

[0012] Further, the lower template further includes a bending block. A fixing groove matching the bending block is provided on the lower die base. The bending block is fixed in the fixing groove. The position of the fixing groove corresponds to the position of the part to be bent on the mounting plate.

[0013] Further, the mold further includes a positioning member with an L-shaped structure. The positioning member includes a positioning section and a connecting section connected perpendicularly to each other. A positioning block groove matching the shape of the connecting section is provided on the lower die base. The positioning member is fixed in the positioning block groove. The number of the positioning members is multiple, and each positioning member contacts and connects the four sides of the lower template.

[0014] Further, an upper cushion block and an upper supporting plate are further provided on the upper die base. One end of the upper cushion block is connected to the upper die base, and the other end is connected to the upper supporting plate. The number of the upper cushion blocks is multiple.

[0015] Further, a lower cushion block and a lower supporting plate are provided on the lower die base. One end of the lower cushion block is connected to the lower die base, and the other end is connected to the lower supporting plate. The number of the lower cushion blocks is multiple.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] (1) In this solution, the mounting plate to be bent is placed above the lower template, and the protrusions on the mounting plate are located in the corresponding protrusion receiving holes. Then, the protruding parts corresponding to the reinforcing ribs on the mounting plate are located inside the first groove on the upper template. With the bending structures of the upper template and the lower template, the mounting plate is bent. The first groove on the upper template cooperates with the protrusion receiving holes on the lower template to protect the double-sided protruding parts on the mounting plate, ensuring that the protruding parts will not be deformed during the bending process and guaranteeing the product quality. At the same time, the lower template with a splicing structure is adopted, and the protrusion receiving holes are separately arranged on multiple sub-templates. Through different combinations of sub-templates, the bending of mounting plates with different protrusion distributions can be realized, reducing the manufacturing cost of the device and expanding the application range of the mold.

[0018] (2) In this solution, trapezoidal connecting blocks are provided on the second and third sub-templates, and a card slot matching the shape of the connecting blocks is provided on the first sub-template. Other sub-templates can be directly snapped into the card slot. The installation method by cooperation connection is convenient and has high relative position accuracy. In addition, it cooperates with the lower die pressing block to fix the lower template on the lower die base, improving the reliability of the connection.

[0019] (3) In this solution, positioning members with an L-shaped structure are provided around the lower template, ensuring the accuracy of the position of the lower template on the lower die base, ensuring that the protrusions on the mounting plate can be accurately matched with the protrusion receiving holes, and ensuring the accuracy of the forming of the mounting plate.
