[0034] Example 1

[0035] like Figs. 1 to 3 As shown, this embodiment provides a stamping and deburring die for an induction cooker mounting plate. The induction cooker mounting plate 1 is provided with mounting holes 11, and the die includes an upper template, a lower template 2, and a limiting component.

[0036] The lower template 2 is provided with a positioning groove 21 that matches the shape of the induction cooker mounting plate 1. The positioning groove 21 includes a rectangular part 22 and an arc part 23 connected to each other. The positioning groove 21 is provided with a deburring punch 24 that corresponds to the position of the mounting hole 11 and matches its shape.

[0037] A limiting groove 25 is provided at the edge of the positioning groove 21. The limiting groove 25 is distributed around the positioning groove 21. The limiting member is installed in the limiting groove 21, and the side of the limiting member close to the positioning groove 21 is tangent to the edge of the positioning groove 21.

[0038] Working principle: The induction cooker mounting plate 1 is placed in the positioning groove 21. The limiting parts set around the positioning groove 21 limit the plane position of the induction cooker mounting plate 1 in the positioning groove, so that the mounting hole 11 on the induction cooker mounting plate 1 is aligned with the corresponding deburring punch 24 in the positioning groove 21. Then, the workpiece is pressed down by the upper template, and the deburring punch 24 enters into the mounting hole 11 to complete the deburring process of the mounting hole 11.

[0039] The induction cooker mounting plate 1 is positioned and plane-limited by the positioning groove 21 and limiting component set on the lower template 2, ensuring that the mounting hole 11 is aligned with the corresponding deburring punch 24 set in the positioning groove 21, thus ensuring the accuracy of deburring the mounting hole 11. Moreover, the lower deburring punch 24 pushes the debris generated by deburring the mounting hole to the upper surface of the workpiece. Compared with the existing mold with deburring punch on the upper template, there is no need to set a special debris collection structure, which simplifies the mold structure, reduces the mold cost, and avoids the residue of debris located under the workpiece, which would cause scratches on the workpiece and damage the product quality.

[0040] In a preferred embodiment, the deburring punch 24 includes a deburring section and a frustum section connected to each other;

[0041] The deburring section is vertically fixed at the bottom of the positioning groove 21, and the frustum section is located at the end of the deburring section away from the lower template. The frustum section is clearance-fitted with the mounting hole 11, and the deburring section is transition-fitted with the mounting hole 11.

[0042] When the induction cooker mounting plate 1 is placed into the positioning groove 21, the frustum section at the upper end of the deburring punch 24 can be initially positioned within the mounting hole 11. This, in conjunction with the limiting component at the edge of the positioning groove 21, provides planar limiting and positioning for the induction cooker mounting plate 1 and the mounting hole, thereby improving the positioning accuracy of the mounting hole 11 and the deburring quality of the subsequent deburring section in the deburring punch 24 on the mounting hole 11.

[0043] In a preferred embodiment, the limiting member is a cylindrical rod structure.

[0044] A cylindrical rod structure is used to limit the periphery of the induction cooker mounting plate 1. The limiting component is in line contact with the induction cooker mounting plate 1. Compared with the existing rectangular structure, it can reduce the possibility of over-limiting the induction cooker mounting plate 1 due to the edge processing precision, thus ensuring the reliability of the limiting and reducing the possibility of deformation of the induction cooker mounting plate 1.

[0045] Optionally, a reset spring is provided at the bottom of the positioning groove 21. One end of the reset spring is fixed on the lower mold base, and the other end movably contacts the induction cooker mounting plate 1.

[0046] Furthermore, the distance between the end face of the return spring away from the lower mold base 3 and the bottom of the positioning groove 21 is less than the distance between the end face of the deburring punch 24 away from the lower mold plate and the bottom of the positioning groove 21.

[0047] The number of reset springs is multiple, and each reset spring is evenly distributed at the bottom of the positioning groove 21.

[0048] By setting a return spring at the bottom of the positioning groove 21, and cooperating with the frustum section at the upper end of the deburring punch 24, when the upper mold is not closed, the induction cooker mounting plate 1 is initially stuck on the frustum section. The return spring contacts the lower end face of the induction cooker mounting plate 1, but is not compressed, thus avoiding interference with the positioning of the induction cooker mounting plate 1 and ensuring its accuracy. After the mold is closed and the induction cooker mounting plate 1 is deburred, the return spring is compressed and reset, pushing the induction cooker mounting plate 1 out of the deburring punch 24, facilitating its removal and improving work efficiency.

[0049] Specifically, the mounting hole 11 includes a circular hole and a square hole, and the deburring punch 24 includes a square column punch and a cylindrical punch. The square column punch mates with the square hole, and the cylindrical punch mates with the circular hole.

[0050] Furthermore, the square cylindrical punches are symmetrically distributed at both ends of the rectangular portion 22, and the cylindrical punches have a triangular structure and are located inside the circle of the arc portion 23.

[0051] Specifically, the mold also includes guide pillars, an upper mold base, and a lower mold base. The guide pillars are fixed on the lower mold base, and the upper mold base has guide holes in which the guide pillars can be movably inserted. A limiting pillar is provided between the upper and lower mold bases to ensure the direction of movement and relative position between them, improving the deburring accuracy and reliability of the mounting plate.

[0052] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
