[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] like Figure 1-4 As shown, this utility model provides an auxiliary positioning component for an automotive mold, including a support plate 1. A hydraulic cylinder 16 is fixedly connected to one side of the support plate 1. One end of the hydraulic cylinder 16 passes through the support plate 1 and is fixedly connected to a top plate 3. Sleeves 2 are fixedly connected to both sides of the top plate 3. A positioning sleeve 8 is provided below the sleeve 2. Inclined blocks 4 are fixedly connected to all four ends of the top plate 3. A positioning block 6 is provided below each inclined block 4. An inclined groove 5 is opened inside the positioning block 6. A connecting block 7 is fixedly connected to one end of the positioning block 6. One end of the connecting block 7 is fixedly connected to one side of the support plate 1. A positioning rod 9 is threaded inside the positioning sleeve 8. One end of the positioning rod 9 is fixedly connected to one side of the support plate 1. A lower template 10 is fixedly connected to the other side of the support plate 1. An upper template 11 is fixedly connected to one side of the top plate 3.

[0025] During the processing of automotive parts, the hydraulic cylinder 16 drives the top plate 3 and the upper template 11 to move. During the mold closing process of the upper template 11 and the lower template 10, the center lines of the positioning sleeve 8 and the sleeve 2 are on the same axis. The two positioning sleeves 8 are embedded inside the sleeve 2. The positioning block 6 has a groove 5 that fits with the inclined block 4. At the same time, the inclined block 4 is inserted into the groove 5. The inclined edge of the inclined block 4 fits with the inclined edge of the groove 5. Through the cooperation between the inclined block 4 and the groove 5, and the cooperation between the positioning sleeve 8 and the sleeve 2, double positioning is achieved, which realizes the precise positioning of the upper template 11 and the lower template 10 during mold closing. At the same time, the positioning sleeve 8 is threaded to one end of the positioning rod 9. When the positioning sleeve 8 wears out after long-term use, the positioning sleeve 8 can be replaced.

[0026] Example 2

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, pressure rods 15 are fixedly connected to both sides of the top plate 3, and a second pressure block 14 is fixedly connected to one end of the pressure rods 15. A first pressure block 13 is provided below the second pressure block 14, and a pressure plate 12 is fixedly connected to one end of the first pressure block 13. A telescopic rod 20 is fixedly connected to one side of the pressure plate 12, and one end of the telescopic rod 20 is fixedly connected to one side of the support plate 1. A spring 21 is sleeved on the outside of the telescopic rod 20, and the two ends of the spring 21 abut against one side of the pressure plate 12 and one side of the support plate 1. Fixed rods 17 are fixedly connected to both ends of one side of the pressure plate 12, and a detection block 18 is fixedly connected to one end of the fixed rod 17. A pressure sensor 19 is provided below the detection block 18, and one end of the pressure sensor 19 is fixedly connected to one side of the support plate 1.

[0028] When the upper template 11 closes with the lower template 10, the second pressure block 14 gradually moves to fit against the first pressure block 13, pushing the first pressure block 13 and the pressure plate 12 downwards. The telescopic rod 20 retracts, the spring 21 is compressed, and the detection block 18 presses down on the pressure sensor 19. Since the center line of the second pressure block 14 is on the same axis as the center line of the first pressure block 13, the pressure sensor 19 is connected to an external display screen to view the pressure values ​​detected by the pressure sensors 19 at both ends of the pressure plate 12. By checking whether the pressure values ​​are consistent, it can be determined whether the second pressure block 14 has shifted during the pressing process, so as to repair and replace the positioning mechanism in time, improve the positioning accuracy, and reduce production losses.

[0029] The usage and working principle of this device are as follows: During the processing of automotive parts, the hydraulic cylinder 16 drives the top plate 3 and the upper template 11 to move. Two positioning sleeves 8 are embedded inside the sleeve 2, and at the same time, the inclined block 4 is inserted into the inclined groove 5. Through the cooperation between the inclined block 4 and the inclined groove 5, and the cooperation between the positioning sleeve 8 and the sleeve 2, the upper template 11 and the lower template 10 are accurately positioned for mold closing. When the positioning sleeve 8 wears out after long-term use, it can be disassembled and replaced. When the upper template 11 closes with the lower template 10, the second pressure block 14 gradually moves to fit against the first pressure block 13, pushing the first pressure block 13 and the pressure plate 12 downward. The telescopic rod 20 retracts, the spring 21 is compressed, and the detection block 18 presses down on the pressure sensor 19. The pressure sensor 19 is connected to an external display screen, which can view the pressure values ​​detected by the pressure sensors 19 at both ends of the pressure plate 12. By checking whether the pressure values ​​are consistent, it can be determined whether the second pressure block 14 has shifted during the downward pressing process, so as to repair and replace the positioning mechanism in a timely manner.
