Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mould, in particular to a bending mould for washing machine control seat. BACKGROUND

[0002] The drum washing machine originated in Europe, and the washing method is designed by imitating the principle of hammering clothes. The control seat is one of the important components of the drum washing machine. The control seat of the drum washing machine needs to be bent during production. Figure 1 As shown in Figure, it is a structure diagram of the control seat of the drum washing machine. Due to the limitation of the shape of the control seat of the drum washing machine, the stroke of the corner bending punch of the existing bending mould for the control seat of the drum washing machine is different from the stroke of the side bending punch. Therefore, the bending mould for the control seat of the drum washing machine has a height difference between the corner bending punch and the side bending punch during design. Although it can solve the problem caused by the different strokes of the two punches and has the characteristics of simple structure and convenient manufacturing, the side of the product is easily damaged during specific bending due to the height difference between the corner bending punch and the side bending punch, which affects the product quality. Therefore, it is urgent to solve the problem. SUMMARY

[0003] The present application relates to the technical field of mould, in particular to a bending mould for washing machine control seat.

[0004] The present application relates to the technical field of mould, in particular to a bending mould for washing machine control seat.

[0005] The present application relates to the technical field of mould, in particular to a bending mould for washing machine control seat.

[0006] As a preferred scheme of the present application, the elastic member is a nitrogen spring.

[0007] As a preferred embodiment of the present invention, the corner bending punch has a guide groove arranged in a vertical direction, and the lower end of the upper pad is provided with a limit block on the outside of the corner bending punch, and the limit block is provided with a guide block that cooperates with the guide groove.

[0008] In a preferred embodiment of the present invention, there are two guide grooves, and correspondingly, there are two guide blocks.

[0009] In a preferred embodiment of the present invention, the guide block and the limiting block are an integral structure.

[0010] The beneficial effects of the present invention are that the bending die of the washing machine control seat is provided with an elastic element so that the corner bending punch and the side bending punch are flush. During bending, the elastic element is compressed under the action of the lower die, and the corner bending punch will not interfere with the workpiece, thus solving the problem of the product side being scratched and effectively ensuring product quality.

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0019] Please refer to Figures 2 to 5 As shown, Figure 2 This is a schematic diagram of the bending die for a washing machine control base in its initial state. Figure 3Another view structure schematic diagram of a bending die for a washing machine control seat in an initial state; Figure 4 Structure schematic diagram of a bending die for a washing machine control seat in another state; Figure 5 Cooperation structure schematic diagram of a corner bending punch and a limiting block.

[0020] In the embodiment, a bending die for a washing machine control seat comprises an upper die seat, a lower die seat, an upper backing plate, a lower backing plate, an upper fixed plate 1, a lower fixed plate, a pressing plate 2, a bending convex die and a bending concave die. The upper backing plate is connected to the lower end of the upper die seat. The pressing plate 2 and the upper fixed plate 1 are connected to the lower end of the upper backing plate. The lower backing plate is connected to the upper end of the lower die seat. The lower fixed plate is connected to the upper end of the lower backing plate. The bending concave die is connected to the upper fixed plate. The bending convex die is installed on the upper fixed plate, and the bending convex die comprises a side bending punch 3 and a corner bending punch 6. The upper part of the corner bending punch 6 is connected with a nitrogen spring 5. The lower end of the nitrogen spring 5 is pressed against the upper end face of the corner bending punch 6, and the upper end of the nitrogen spring 5 is pressed against the lower end face of the upper backing plate. In the initial state, the corner bending punch 6 extends downward under the action of the nitrogen spring 5 so as to be flush with the side bending punch 3.

[0021] In order to ensure that the corner bending punch 6 does not deviate when moving up and down, in the embodiment, a guide groove is formed in the corner bending punch 6. The guide groove is arranged in the vertical direction. A limiting block 4 is arranged outside the corner bending punch 6 at the lower end of the upper backing plate. A guide block 7 is arranged on the limiting block 4 and cooperates with the guide groove. In the embodiment, the guide groove is two, and the guide block 7 is two correspondingly.

[0022] In order to facilitate production and manufacturing, in the embodiment, the guide block 7 and the limiting block 4 are an integral structure.

[0023] The bending die for the washing machine control seat sets the nitrogen spring 5 so that the corner bending punch 6 is flush with the side bending punch 3. When bending, the nitrogen spring 5 is compressed under the action of the lower die so that the corner bending punch 6 moves upward relative to the side bending punch 3. The corner bending punch 6 does not interfere with the workpiece, which solves the problem that the product side is scratched and effectively ensures the product quality.

[0024] The above embodiments only illustrate the basic principles and characteristics of the present application. The present application is not limited by the above embodiments. Various changes and modifications can be made without departing from the spirit and scope of the present application. These changes and modifications fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims.
