DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a stamping die for the rear section of the left rear longitudinal beam that is easy to replace includes a lower die 1 and an upper die 2. The lower die 1 is composed of a first main body 5 and a first forming module 7. The upper die 2 is composed of a second main body 6 and a second forming module 8. A connecting component 3 and a fixing component 4 are installed on both the lower die 1 and the upper die 2. The connecting component 3 and the fixing component 4 connect the first main body 5 with the first forming module 7 and the second main body 6 with the second forming module 8. The connecting component 3 is composed of a base plate 13 and an insert 14. There are two inserts 14 that are symmetrically installed at one end of the base plate 13. The fixing component 4 is composed of a connecting plate 16, a connecting rod 17, and an elastic member 18. The connecting rod 17 is composed of a spring 18 and a square rod 19. There are two connecting rods 17 and they are symmetrically fixed on one end of the connecting plate 16. There are two springs 18 and they are respectively sleeved on the two connecting rods 17. There are two square rods 19 and they are respectively fixed on one end of the two connecting rods 17. One end of the first forming module 7 and the second forming module 8 is provided with a receiving groove 9. One end of the first forming module 7 and the second forming module 8 is symmetrically provided with two connecting grooves 10. The first forming module 7 and the second forming module 8 are symmetrically provided with two square holes 11 and two round holes 12. The square hole 11 is connected to the connecting groove 10, and the round hole 12 is connected to the connecting groove The receiving groove 9 is connected, and the square hole 11 and the round hole 12 are also connected to each other. When the stamping die is used to produce the rear section of the left rear longitudinal beam, the material for producing the rear section of the left rear longitudinal beam can be placed on the first forming module 7 first, and then the upper die 2 is pushed downward by the hydraulic equipment. Finally, under the extrusion of the first forming module 7 and the second forming module 8, the material will be processed into the required shape. When the first forming module 7 and the second forming module 8 are worn and need to be replaced, the square rod 19 on the fixing assembly 4 can be pulled out from the socket 15 opened on the plug block 14, and then the first forming module 7 and the second forming module can be replaced. The molding module 8 is removed, and then the new first molding module 7 and the second molding module 8 are installed on the connecting component 3, and the square rod 19 on the fixing component 4 is inserted into the socket 15. By arranging the connecting component 3 and the fixing component 4 on the upper mold 1 and the lower mold 2 so that they cooperate with each other, the first body 5 and the first molding module 7, the second body 6 and the second molding module 8 can be separated more simply and conveniently, thereby making the separation efficiency of the first body 5 and the first molding module 7, the second body 6 and the second molding module 8 higher, which is beneficial to improving the efficiency of the stamping die in producing workpieces.

[0021] Furthermore, the substrates 13 on the two connecting components 3 are respectively fixedly mounted on one end of the first main body 5 and the second main body 6, and the plug 14 on the connecting component 3 can be inserted into the connecting groove 10. A socket 15 is provided on the plug 14. When the first molding module 7 and the second molding module 8 are removed from the connecting component 3, the first molding module 7 and the second molding module 8 can be moved away from the connecting component 3, so that the plug 14 is passively moved out of the connecting groove 10. Conversely, when the first molding module 7 and the second molding module 8 need to be installed on the connecting component 3, the first molding module 7 and the second molding module 8 can be moved toward the connecting component 3, and finally the plug 14 is inserted into the connecting groove 10.

[0022] Furthermore, the two fixing components 4 are respectively installed in the first forming module 7 and the second forming module 8, the connecting plate 16 can be received in the receiving groove 9, the spring 18 is located in the square hole 11, the connecting rod 17 passes through the round hole 12 and the square hole 11, the square rod 19 on the fixing component 4 can be inserted into the socket 15 opened on the plug block 14, and the square rod 19 can be retracted into the square hole 11. When the first forming module 7, the second forming module 8 and the connecting component 3 are separated, the connecting plate 16 can be pulled outward. At this time, the connecting plate 16 will pull the square rod 19 through the connecting rod 17, so that the square rod 19 will eventually be completely removed from the socket 15. At this time, the square rod 19 will be in the square hole 11, and the spring 18 will be compressed by the square rod 19; when the first forming module 7 and the second forming module 8 are installed on the connecting assembly 3, the square rod 19 must first be completely retracted into the square hole 11. When the insert block 14 is inserted into the connecting groove 10, the connecting plate 16 is loosened. At this time, under the elastic force of the spring 18, the square rod 19 can be inserted into the socket 15.
