[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] See also Figure 1 and Figure 2 , a fender forming punching die, comprising an upper cover die core 1 and a lower cover die core 2 which are interlocked;

[0022] In a specific embodiment, the lower cover mold 2 is fixedly installed, and the upper cover mold 1 is engaged with or separated from the lower cover mold 2 by a lifting device, such as a telescopic cylinder.

[0023] The upper cover mold core 1 includes an upper cover support frame 101, in which an upper cover circulating water cooling pipe 102 is laid, and lifting support rings 103 are installed at the four vertices of the outer side of the upper cover support frame 101. A plurality of ejector pins 104 are installed on the outer side wall of the upper cover support frame 101.

[0024] The upper cover support frame 101 includes a plurality of upper cover support ribs 105 , and the plurality of upper cover support ribs 105 are respectively arranged at intervals along the length direction and the width direction of the upper cover support frame 101 .

[0025] The upper cover circulating water cooling pipe 102 is connected to the upper cover supporting rib 105 .

[0026] In a specific embodiment, a plurality of upper cover support ribs 105 are staggered in intervals in the frame of the upper cover support frame 101, so that the accommodation space in the frame of the upper cover support frame 101 is divided into a plurality of upper cover accommodation spaces, which can enhance the firmness of the upper cover support frame 101;

[0027] The upper cover circulating water cooling pipe 102 is laid on the surface of the upper cover supporting rib 105 . In order to enhance the stability of the upper cover circulating water cooling pipe 102 , the upper cover circulating water cooling pipe 102 can penetrate the upper cover supporting rib 105 .

[0028] The ejector pin 104 is used to fix the die material to be punched, and the die material is formed into a fender after being punched by the fender forming mold.

[0029] The upper cover circulating water cooling pipe 102 is used to cool the punching die material.

[0030] The lower cover mold 2 includes a lower cover support frame 201, and the lower cover support frame 201 includes a plurality of lower cover support ribs 202. The plurality of lower cover support ribs 202 are respectively arranged at intervals along the length direction and the width direction of the lower cover mold 2, thereby dividing the inner side of the lower cover mold 2 into a plurality of lower cover accommodating spaces.

[0031] See also Figure 3 The lower cover mold core 2 also includes a lower cover circulating water cooling pipeline, and the lower cover circulating water cooling pipeline 202 is distributed in the lower cover mold core 2.

[0032] In a specific implementation, the lower cover circulating water cooling pipeline passes through the lower cover supporting rib 202 from one lower cover accommodating space and enters the adjacent lower cover accommodating space, which is reasonably distributed and enhances the stability of the lower cover circulating water cooling pipeline.

[0033] The lower cover circulating water cooling pipeline is connected to the lower cover supporting rib 202 .
