[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a flanging tool for automobile molds includes a tool 1, a connecting part 2 and a flanging part 3. A mounting groove 11 is provided at the lower end of the tool 1. The connecting part 2 is movably sleeved in the mounting groove 11. Slots 12 are provided on the inner walls on both sides of the mounting groove 11. A slide groove 8 is provided on the connecting part 2. A partition is fixedly provided in the middle of the slide groove 8. Reset springs 10 are fixedly connected on both sides of the partition. Blocks 9 are fixedly connected at the other ends of the two reset springs 10. The two blocks 9 are movably sleeved in two slots 12 respectively. Disassembly bolts 13 are threadedly sleeved on both sides of the tool 1. One end of the disassembly bolt 13 passes through the slot 12.

[0024] In this embodiment, the two return springs 10 are movably sleeved in the slide groove 8, and the upper ends of the two clamping blocks 9 protrude from one side of the slide groove 8 and are made of an inclined structure, so that when the connecting part 2 is installed, the clamping blocks 9 are automatically pushed into the slide groove 8.

[0025] In this embodiment, the opposite ends of the two disassembly bolts 13 penetrate the tool 1 and are fixedly sleeved with a rotating cap. The opposite ends of the two disassembly bolts 13 are respectively arranged at the side positions of the opposite ends of the two clamping blocks 9, so that the disassembly bolts 13 can be driven to rotate by the rotating cap.

[0026] In this embodiment, fixed plates 4 are fixedly connected to the outer walls on both sides of the tool 1, and buffer spring pins 5 are fixedly connected to the lower ends of the two fixed plates 4. The lower ends of the two buffer spring pins 5 are fixedly connected to pressure plates 6, and the pressure plates 6 are used to assist in pre-pressing the mold to avoid warping when the mold is stamped.

[0027] In this embodiment, the two buffer spring pins 5 each include a buffer pin and a buffer spring, and the buffer spring is movably sleeved on the outer end of the buffer pin, so that the impact force generated by stamping is buffered by the buffer spring pin 5 .

[0028] In this embodiment, condensers 7 are fixedly provided on both sides of the tool 1, and the condensers 7 on both sides of the tool 1 are connected, and the water inlet and outlet of the condenser 7 pass through the tool 1 and are connected to the outside. The water inlet and outlet of the condenser 7 are connected to an external coolant circulation device through a hose, and the tool 1 is cooled by the circulation of the coolant in the tool 1, and then the flange part 3 is cooled through the connecting part 2.

[0029] In this embodiment, the condenser 7 is arranged in an S-shaped structure distribution to increase the contact area, thereby improving the cooling effect, and two disassembly bolts 13 are arranged between two adjacent upper and lower pipes of the condenser 7.

[0030] It should be noted that the utility model is a flanging knife for automobile molds. When in use, the flanging part 3 is driven by the tool 1 to perform flanging stamping. At the same time, the condenser 7 is connected to an external coolant circulation device to supply coolant, thereby realizing cooling of the tool 1, and then cooling of the flanging part 3 is achieved through the connecting part 2, to prevent the flanging part 3 from being overheated due to frequent stamping, thereby affecting production. When it is necessary to stamp different flanging molds, the disassembly bolt 13 is rotated to press the clamping block 9 out of the clamping groove 12, and the connecting part 2 can be removed from the mounting groove 11, thereby performing corresponding replacement of the flanging part 3. After the replacement is completed, the corresponding flanging part 3 will be installed into the mounting groove 11 through the connecting part 2. When the clamping block 9 moves to the position of the clamping groove 12, under the action of the reset spring 10, the clamping block 9 extends into the clamping groove 12 to engage, thereby fixing the connecting part 2 in the mounting groove 11, and completing the rapid installation of the flanging part 3.
