[0027] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0028] Reference Figure 1-5 The utility model embodiment is a stamping forming mold for a side beam reinforcement plate of an automobile, which includes an upper support plate 1, a positioning column 3 is fixedly connected to the lower surface of the upper support plate 1, and the lower end of the positioning column 3 is fixedly connected to the lower support plate 2, and the lower surface of the upper support plate 1 is fixedly connected to the hydraulic cylinder 4, and the output end of the hydraulic cylinder 4 is fixedly connected to the upper pressure plate sleeve 5, and the upper side of the upper pressure plate sleeve 5 is threadedly connected with a pin 7, and the two sides of the upper pressure plate sleeve 5 are fixedly connected with sliders 11, and the slider 11 is slidably connected to the positioning column 3. A groove 12 is opened on the inner side of the lower surface of the upper pressure plate sleeve 5, and the groove 12 is slidably connected to the upper pressure plate 6, and pin sockets 63 are opened on both sides of the upper pressure plate 6, and a second positioning hole 62 is opened in the middle of the upper pressure plate 6, and upper pressure block positioning holes 61 are opened on both sides of the middle of the upper pressure plate 6, and a mold protrusion 64 is fixedly connected to the lower surface of the upper pressure plate 6.

[0029] The above structure can make the upper pressure plate sleeve 5 move up and down by the drive of the hydraulic cylinder 4. By providing a slider 11, the upper pressure plate sleeve 5 can be limited so that the upper pressure plate sleeve 5 will not move left and right when descending. By providing a pin 7, the upper pressure plate sleeve 5 and the upper pressure plate 6 can be combined together so that the upper pressure plate 6 will not move forward and backward during operation.

[0030] The upper surface of the lower support plate 2 is fixedly connected with a lower pressure plate sleeve 8, the upper surface of the lower pressure plate sleeve 8 is fixedly connected with a first positioning pin 10, the upper surface of the lower pressure plate sleeve 8 is provided with a lower pressure plate 9, lower pressure block positioning openings 91 are provided on both sides of the upper surface of the lower pressure plate 9, a second positioning pin 93 is fixedly connected in the middle of the upper surface of the lower pressure plate 9, and a mold groove 92 is provided on the upper surface of the lower pressure plate 9.

[0031] The above structure can fix the lower pressing plate 9 by providing the first positioning pin 10, so that it will not move when placed in the lower pressing plate sleeve 8, thereby ensuring the stability of the lower pressing plate 9 during the stamping process. By providing the second positioning pin 93, both ends of the raw material are inserted therein, so that the raw material will not fail to be stamped due to displacement during the stamping process.

[0032] The first positioning pin 10 fixedly connected to the upper surface of the lower pressure plate sleeve 8 corresponds to the lower pressure block positioning hole 91 opened through the lower pressure plate 9 and the upper pressure block positioning hole 61 opened on the upper pressure plate 6, and the second positioning pin 93 fixedly connected to the lower pressure plate 9 corresponds to the second positioning hole 62 of the upper pressure plate 6.

[0033] In the above structure, each positioning pin corresponds to the positioning opening, which ensures that the upper pressing plate 6 and the lower pressing plate 9 are completely fitted together during the stamping process, thereby ensuring the accuracy of the stamping.

[0034] Working principle: Before using the automobile side beam reinforcement plate, first, insert the upper pressure plate 6 corresponding to the side beam reinforcement plate into the groove 12, and then insert the pin 7 therein to stably fix the upper pressure plate 6 in the upper pressure plate sleeve 5. Second, completely insert the lower pressure plate 9 corresponding to the side beam reinforcement plate into the first positioning pin 10. The preparation work is now complete. When using the automobile side beam reinforcement plate, first, open holes at both ends of the raw material and insert them into the second positioning pin 93. Then, turn on the switch of the hydraulic cylinder 4, and drive the upper pressure plate sleeve 5 under the drive of the hydraulic cylinder 4. Move downward, and under the limitation of the slider 11, the upper pressure plate sleeve 5 will not shake left and right, and keep vertical descent. When the second positioning pin 93 is inserted into the second positioning port 62 and the first positioning pin 10 is inserted into the upper pressure block positioning port 61, the stamping process begins. When the upper pressure plate 6 fits the lower pressure plate 9, the stamping is completed. Adjust the switch of the hydraulic cylinder 4 so that the hydraulic cylinder 4 drives the upper pressure plate sleeve 5 to rise. When the upper pressure plate sleeve 5 rises to the upper dead point, turn off the switch of the hydraulic press. At this time, take the stamped automobile side beam reinforcement plate out of the mold groove 92.
