[0024] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0025] See also Figure 1-Figure 4 In order to solve the problems in the prior art, the utility model provides a car door panel stamping die 1, the stamping die 1 includes a die assembly 11, a positioning assembly 12, a mounting seat 13 and a bracket 14. The die assembly 11 includes an upper die 111 and a lower die 112. The mounting seat 13 is provided with two along the same vertical line. The upper die 111 and the lower die 112 are respectively installed on one of the mounting seats 13. The surface of the mounting seat 13 is provided with a slide groove 131. The surfaces of the upper die 111 and the lower die 112 are provided with a slide rail 113 slidably connected to the slide groove 131. A stamping drive member 141 is installed on the bracket 14. The output end of the stamping drive member 141 is fixedly connected to the mounting seat 13 on the upper die 111, and the stamping drive member 141 can drive the upper die 111 to buckle with the lower die 112; the positioning assembly 12 is provided with at least two groups, and the positioning assembly 12 is located on the side of the mounting seat 13 and abuts against the slide rail 113.

[0026] When using the stamping die 1 of the present invention, the door panel is first placed on the lower die 112, and then the stamping drive member 141 is controlled to descend so that the upper die 111 and the lower die 112 are engaged, and the door panel is stamped into a door panel under the stamping action of the upper die 111 and the lower die 112. When the upper die 111 or the lower die 112 is worn and the stamping accuracy of the door panel is affected, the positioning assembly 12 can be moved and the positioning assembly 12 is moved away from the surface of the slide rail 113 to make the upper die 1 The upper mold 111 and the lower mold 112 can slide along the slide groove 131 on the mounting seat 13, and then the upper mold 111 and the lower mold 112 can be removed from the mounting seat 13, so that the operator can repair and replace the removed upper mold 111 and the lower mold 112. Compared with the method of directly repairing the upper mold 111 and the lower mold 112 on the stamping mold 1, the stamping mold 1 of the present invention can reduce the limitations of the operator when repairing the upper mold 111 and the lower mold 112, and improve the repair efficiency.

[0027] In an embodiment of the present invention, the positioning assembly 12 includes at least two positioning plates 121, and a positioning groove 132 perpendicular to the slide groove 131 is opened on the surface of the mounting seat 13. The positioning plate 121 is inserted into the positioning groove 132 and abuts against the slide rail 113, so that after the positioning plate 121 is inserted into the positioning groove 132, it plays a role in limiting the slide rail 113, thereby preventing the slide rail 113 from being displaced in the slide groove 131 and affecting the stamping accuracy of the door panel.

[0028] See also Figure 3 and Figure 4 In an embodiment of the present invention, the positioning assembly 12 also includes a hinge plate 122, a positioning base 123, an elastic member 124 and a positioning rod 125. The positioning base 123 is fixed to one side of the mounting base 13 for hinged connection of the hinge plate 122. The elastic member 124 and the positioning rod 125 are respectively located on both sides of the positioning base 123, and under the elastic force of the elastic member 124, the hinge plate 122 is driven to press the positioning rod 125 against the slide rail 113, so as to prevent the slide rail 113 from moving under the pressing action of the positioning rod 125 on the slide rail 113, thereby improving the stamping accuracy of the stamping die 1 on the door panel.

[0029] In an embodiment of the present invention, positioning holes 114 are provided on the sides of the slide rail 113, and a through hole is provided on the positioning plate 121 for the positioning rod 125 to pass through. After the positioning rod 125 passes through the through hole, it is plugged into the positioning hole 114. Therefore, after the positioning rod 125 is inserted into the through hole and the positioning hole 114, the positioning plate 121 is restricted from being disengaged from the limiting groove under the action of the positioning rod 125 and the slide rail 113. At the same time, the slide rail 113 is restricted from being displaced under the action of the positioning rod 125 and the positioning plate 121, thereby preventing the upper mold 111 from changing its position on the mounting seat 13. Similarly, the position of the lower mold 112 on the mounting seat 13 can also be prevented from changing.

[0030] See also Figure 4 In the embodiment of the present invention, the slide groove 131 is a T-shaped slide groove 131, comprising a transverse groove and a vertical groove perpendicular to each other. The diameter of the positioning rod 125 matches the diameter of the transverse groove, so that after the positioning rod 125 is inserted into the positioning hole 114, it is aligned with the through hole. Under the action of the hinge plate 122 and the elastic member 124, the positioning rod 125 is squeezed into the through hole, thereby fixing the position of the slide rail 113. In other words, the upper mold 111 and the mounting seat 13 are relatively fixed. Similarly, the lower mold 112 and the mounting seat 13 are also relatively fixed. At the same time, the transverse groove can limit the vertical displacement of the positioning rod 125, and the positioning hole 114 and the through hole can limit the left and right displacement of the positioning rod 125. In addition, the positioning rod 125 can prevent the positioning plate 121 from disengaging from the positioning groove 132, thereby improving the connection stability between the upper mold 111 and the mounting seat 13, and improving the connection stability between the lower mold 112 and the mounting seat 13.

[0031] When the positioning plate 121 is in the position corresponding to the vertical slot, the positioning plate 121 can be pulled out of the positioning slot 132, thereby improving the convenience of use of the positioning assembly 12 and thereby improving the efficiency of disassembly and assembly of the upper mold 111 or the lower mold 112.

[0032] See also Figure 1 and Figure 2 In an embodiment of the present invention, protruding guide portions 133 are provided on both sides of the mounting seat 13 in the length direction, and guide posts 142 are provided at positions corresponding to the guide portions 133 on both sides of the bracket 14. The guide posts 142 pass through the guide portions 133 to provide guidance for the movement of the upper mold 111, so as to improve the movement stability when the upper mold 111 and the lower mold 112 are covered. Since the upper mold 111 and the mounting seat 13 are connected by means of the slide rail 113 and the slide groove 131, when the upper mold 111 and the mounting seat 13 need to be disassembled and assembled, it is only necessary to remove the guide rod on one side so that the upper mold 111 can be inserted into the mounting seat 13, and the upper mold 111 and the mounting seat 13 can be positioned under the action of the positioning assembly 12.

[0033] Similarly, when the lower mold 112 and the mounting seat 13 need to be disassembled and assembled, it is only necessary to remove the guide rod on one side so that the lower mold 112 can be inserted into the mounting seat 13 and positioned under the action of the positioning assembly 12.

[0034] In an embodiment of the present invention, a gripping hole is provided on the positioning plate 121, the length of the gripping hole ranges from 10cm to 15cm, and the width of the gripping hole ranges from 4cm to 8cm, so that the operator can grab the positioning plate 121 from the gripping hole when disassembling and assembling the positioning plate 121, thereby improving the disassembly and assembly efficiency of the positioning plate 121.

[0035] In an embodiment of the present invention, a cutting knife 1111 is provided around the upper mold 111, and a cutting groove 1121 is provided around the lower mold 112. When the upper mold 111 and the lower mold 112 are covered, the cutting knife 1111 is inserted into the cutting groove 1121 to cut the door panel, thereby avoiding the situation where the stamped door panel has burrs and burrs around it. There is no need for secondary processing of the burrs, thereby improving the stamping efficiency of the door panel.

[0036] In an embodiment of the present invention, cutting knives 1112 are provided on both sides of the cutting knife 1111, and cutting grooves 1122 are provided on both sides of the cutting groove 1121. When the upper mold 111 and the lower mold 112 are covered, the cutting knife 1112 is inserted into the cutting groove 1122 to cut the cut door panel into two halves, so that the operator can move the two halves of the door panel out from both sides of the lower mold 112 respectively, avoiding the cut door panel being surrounded by the lower mold 112, which makes it difficult for the operator to remove the door panel.
