[0002] In the automotive manufacturing industry, automotive gears are key components, and their production quality and efficiency have a significant impact on the overall performance and production cycle of automobiles. Stamping dies are the core equipment for automotive gear production, and their performance directly determines the quality, production efficiency, and manufacturing cost of gears.

[0003] Traditional automotive gear stamping dies have several shortcomings in practical applications. For example, the replacement process of the moving and fixed dies is complex, requiring the use of multiple tools for disassembly and installation, and it is difficult to ensure the consistency of the installation position each time, leading to a decrease in stamping accuracy. Frequent die changes not only prolong production preparation time and reduce production efficiency but also increase production costs. Because the dies are subjected to significant pressure and impact during stamping, traditional positioning methods cannot ensure the accurate relative position between the moving and fixed dies, thus affecting the stamping accuracy of the gears and resulting in unstable product quality. The control and adjustment methods of traditional stamping dies are relatively complex, requiring a high level of technical skill from operators, increasing the risk of human error, and reducing production safety and reliability.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for an automotive gear stamping die with an ejector mechanism: it includes a stamping machine body 1, an ejector rod 2, and a pressure plate 3. The stamping machine body 1 provides power support for the entire stamping process and ensures the stability of the entire die system. The ejector rod 2 is slidably connected to the top of the stamping machine body 1. The ejector rod 2 is controlled by a sensor and can eject the processed workpiece from the die, thereby achieving the demolding effect. One end of the ejector rod 2 is fixed with a pressure plate 3. The main function of the pressure plate 3 is to support the upper die, ensure that the upper die is evenly stressed during the stamping process, and guarantee the stamping quality.

[0022] The bottom end of the pressure plate 3 is fixed with a mold carrier 4. The main function of the mold carrier 4 is to quickly connect and replace the moving mold. The bottom end of the mold carrier 4 is slidably connected to the moving mold 5. The moving mold 5, through cooperation with the mold carrier 4 and the positioning pin 6, can achieve quick replacement and simple and fast operation. The bottom end of the mold carrier 4 is provided with a sliding groove, and the top end of the moving mold 5 is fixed with a slider. The slider matches the sliding groove at the bottom end of the mold carrier 4. Through the cooperation of the sliding groove and the slider, the operator can quickly replace the moving mold. The slider is provided with a through hole, and one side wall of the mold carrier 4 is provided with a through hole. The inner wall of the through hole is slidably connected with the positioning pin 6. The positioning pin 6 can ensure the consistency of the moving mold 5's installation position each time, and ensure that the relative position between the moving mold 5 and the mold carrier 4 is accurate, thereby ensuring stamping accuracy.

[0023] A fixed mold 7 is provided below the moving mold 5. The main function of the fixed mold 7 is to match the moving mold and extrude the workpiece to form it. A fixing member 8 is fixed at the bottom of the fixed mold 7. A sliding groove is provided at the connection between the fixed mold 7 and the stamping machine body 1. The sliding groove allows the fixing member 8 at the bottom of the fixed mold 7 to slide inside itself. An extrusion positioning member is slidably connected to one side of the fixing member 8. The extrusion positioning member can apply the pressure it receives to the fixing member 8 to extrude and position it.

[0024] The extrusion positioning component includes an extruder 9, one side of which is attached to one side wall of a fixing component 8. A connecting rod 10 is fixed to the side of the extruder 9 away from the fixing component 8. The connecting rod 10 cooperates with the extruder 9 to apply pressure to the fixing component 8 to fix it. An elastic element 12 is sleeved on the outer wall of the connecting rod 10. The main function of the elastic element 12 is to assist the extruder 9 and the connecting rod 10 in resetting, preparing for the next mold change. A resisting element 13 is fixed to one side of the elastic element 12. The function of the resisting element 13 is to counteract the reaction force of the elastic element 12, so that it can better drive the extruder 9 and the connecting rod 10 to reset.

[0025] The outer wall of the extrusion positioning component is fitted with a first limiting member 11, and the outer wall of the extrusion positioning component away from the first limiting member 11 is fitted with a second limiting member 14. The function of the first limiting member and the second limiting member is to ensure that the connecting rod 10 always moves left and right on a horizontal line during operation, so as to ensure the stable fixation of the fixing member 8. The side of the extrusion positioning component away from the first limiting member 11 is slidably connected to a transmission rod 15. The end of the transmission rod 15 that contacts the connecting rod 10 is wedge-shaped. When the transmission rod 15 moves upward, the wedge-shaped structure can push the connecting rod 10 to the designated position.

[0026] A third limiting member 16 is sleeved on the outer wall of the transmission rod 15. The main function of the third limiting member 16 is to limit the left and right displacement of the transmission rod 15, so that it can only move up and down. An eccentric wheel 17 is attached to the bottom end of the transmission rod 15. The eccentric wheel 17 is rotated by the control hand. When the eccentric wheel 17 rotates, it will fix the fixing member 8 through the transmission rod 15 and the connecting rod 10.

[0027] Working Principle: When using an automotive gear stamping die with an ejection mechanism, the moving die 5 must first be placed in the designated position, ensuring the slide at the top of the moving die 5 is level with the groove at the bottom of the die holder 4. Then, the moving die 5 is pushed into the bottom of the die holder 4 through the engagement of the groove and the slide, creating a sliding connection. Next, the locating pin 6 is inserted through a through hole on one side wall of the die holder 4, tightly fixing the die holder 4 and the moving die 5. Then, the fixed die 7 is placed in the designated position, ensuring the fixing member 8, which is fixedly connected to the fixed die 7, is level with the groove in the stamping machine body 1. Finally, the fixed die 7 is connected to the slide through the fixing member 8... The groove is pushed into the designated position, and then the control hand is rotated. The control hand drives the eccentric wheel 17 to rotate. Because the eccentric wheel 17 is biased to one side, it will push the transmission rod 15 that is in contact with it upward when it rotates. Since the end of the transmission rod 15 that contacts the connecting rod 10 is wedge-shaped, the connecting rod 10 will move left and right due to the wedge shape when the transmission rod 15 moves upward. When the connecting rod 10 is pushed, it will transmit the pushing force to the extrusion part 9, so that the extrusion part 9 will press and fix the fixing part 8. At this time, the mold installation is completed. After fine calibration, the workpiece can be stamped.

[0028] When it is necessary to change the mold, the positioning pin 6 should be removed from the through hole on the side wall of the mold base 4. Then, the moving mold 5 should be slowly pulled out from the mold base 4 through the slider and the slide. Then, the control hand should be rotated to drive the eccentric wheel 17 to rotate. At this time, the eccentric wheel 17 no longer applies upward thrust. The transmission rod 15 returns to its original position due to the loss of thrust. The connecting rod 10 also returns to its original position due to the elastic force of the elastic element 12. The extrusion part 9 will release the extrusion fixation of the fixing part 8. At this time, the fixed mold 7 can be slowly removed and replaced.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
