[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0026] Reference Figures 1-8 A molding die for automotive parts includes a platform 1. A U-shaped plate is fixedly installed on the upper surface of the platform 1. A hydraulic cylinder 2 is fixedly installed on the upper surface of the U-shaped plate. An mounting plate is fixedly installed on the drive shaft of the hydraulic cylinder 2. A stamping plate 3 is fixedly installed on the lower surface of the mounting plate. A forming groove 4 is formed on the upper surface of the platform 1. A collecting groove 5 is formed on the surface of the platform 1. An opening communicating with the collecting groove 5 is formed at the bottom of the forming groove 4. A pair of hollow rods 6 are fixedly installed on the left and right side walls of the collecting groove 5. Insert rods 7 are slidably inserted into the hollow rods 6. The insert rods 7 are connected to the groove wall of the collecting groove 5 through a telescopic component. The telescopic component includes a telescopic spring 15. The two ends of the telescopic spring 15 are fixedly connected to the ends of the insert rods 7 and the groove wall of the collecting groove 5, respectively. A bearing plate 8 is fixedly installed at the ends of each pair of insert rods 7.

[0027] L-shaped rods 9 are fixedly sleeved on every two insertion rods 7. Rectangular openings 10 are symmetrically opened on the upper surface of the platform 1. The top ends of the two L-shaped rods 9 pass through the two rectangular openings 10 respectively, and inclined plates 11 are fixedly installed on each. U-shaped abutment rods 12 are symmetrically fixedly installed on the surface of the mounting plate. Through openings 13 for the abutment rods 12 to pass through are opened on the surface of the inclined plate 11. A rotating shaft is rotatably installed in the through opening 13. A baffle 14 is fixedly sleeved on the rotating shaft. The surface of the baffle 14 is connected to the opening wall of the through opening 13 through an elastic component. The elastic component includes a torsion spring 16 sleeved on the rotating shaft. The two ends of the torsion spring 16 are fixedly connected to the surface of the baffle 14 and the opening wall of the through opening 13 respectively. The rotation direction of the baffle 14 is limited by a rotation limiting component. The rotation limiting component includes a sliding rod 17 fixedly installed on the surface of the baffle 14. An arc-shaped sliding opening 18 is opened on the surface of the inclined plate 11 with the rotating shaft as the center. The sliding rod 17 is slidably arranged in the sliding opening 18.

[0028] When the stamping plate 3 is at its highest position, the two supporting plates 8 will abut against each other. At this time, the two abutting rods 12 will correspond to the positions of the two through holes 13 respectively. Then, the sheet material to be stamped is placed in the forming groove 4, and the lower surface of the sheet material will abut against the upper surfaces of the two supporting plates 8. Then, the hydraulic cylinder 2 is activated to control the stamping plate 3 to move downward. During the downward movement, the two abutting rods 12 will move downward together, and the lower surfaces of the two abutting rods 12 will abut against the upper surfaces of the two baffles 14 respectively. Under the pressure of the abutting rods 12, the baffles 14 will rotate. At this time, the sliding rod 17 will also slide in the sliding opening 18 until the abutting rods 12 move down to no longer contact the baffles 14. Then, the baffles 14 will quickly rotate and reset under the elastic potential energy of the torsion spring 16, and the sliding rod 17 will quickly slide into the sliding opening 18 and abut against the opening wall of the sliding opening 18. Then, when the stamping plate 3 completes the stamping of the sheet material, When the hydraulic cylinder 2 moves the stamping plate 3 upward and resets, the two abutment rods 12 will abut against the lower surfaces of the two baffles 14 respectively. However, due to the restriction of the sliding rod 17 and the sliding opening 18, the end of the baffle 14 away from the rotating shaft cannot rotate upward. As a result, the abutment rod 12 will slide into contact with the lower surface of the baffle 14, and then slide into contact with the inclined surface of the inclined plate 11. Under the action of the inclined surface, the two bearing plates 8 will move away from each other, and the multiple telescopic springs 15 will contract together until the bearing plate 8 moves to the point where it no longer contacts the plate. At this point, the bearing effect on the plate disappears, and the plate will fall into the collection trough 5, thus completing the automatic unloading. When the stamping plate 3 moves upward and resets, the two abutment rods 12 will no longer contact the inclined plate 11. The two bearing plates 8 will then move and reset rapidly under the elastic potential energy of the multiple telescopic springs 15 and abut against each other, so that the plates to be processed later can be placed in the forming trough 4.

[0029] The insert rod 7 is slidably and sealed inside the hollow rod 6. An air inlet pipe 19 is fixedly installed on the lower surface of the hollow rod 6, and an air outlet pipe 20 is fixedly installed on the upper surface of the hollow rod 6. The top end of the air outlet pipe 20 passes into the platform 1, and multiple air vents 21 are fixedly installed on the surface of the top end of the air outlet pipe 20. The ends of the multiple air vents 21 away from the air outlet pipe 20 are distributed around the walls of the forming groove 4. Both the air outlet pipe 20 and the air inlet pipe 19 are equipped with one-way valves. The one-way valve in the air outlet pipe 20 is directed from inside the hollow rod 6 to the multiple air vents 21, and the one-way valve in the air inlet pipe 19 is directed from the outside to inside the hollow rod 6.

[0030] When the two supporting plates 8 move away from each other, the sheet material formed in the forming groove 4 needs to be unloaded. At this time, the insert rod 7 will move into the hollow rod 6. The volume of the space inside the hollow rod 6 will decrease and the pressure will increase. The gas inside the hollow rod 6 will enter the multiple ventilation pipes 21 from the air outlet pipe 20 and be ejected, injecting compressed air into the space between the side wall of the sheet and the wall of the forming groove 4 to form an air film, reducing the friction of the contact surface, so that the sheet can be separated from the forming groove 4 under the action of gravity. After the stamping is completed, the wall of the forming groove 4 and the sheet are tightly attached due to plastic deformation, making it difficult to complete the automatic unloading under its own gravity.

[0031] When the two support plates 8 approach each other, the insert rod 7 moves outward from the hollow rod 6, the volume of the space inside the hollow rod 6 increases, the pressure decreases, and the gas located outside will enter the hollow rod 6 through the air inlet pipe 19.

[0032] The bottom of the collection tank 5 is bonded with a protective pad 22. The protective pad 22 is made of rubber. The rubber protective pad 22 has good elasticity and adhesion, which can play a certain buffering role and prevent the plate from directly colliding with the bottom of the collection tank 5 and being damaged.

[0033] In this invention, when the stamping plate 3 completes the stamping of the sheet material located in the forming groove 4, during the upward movement, the two bearing plates 8 located at the bottom of the forming groove 4 will move away from each other, so that the formed sheet material will automatically fall into the collection groove 5, completing the automatic unloading without manual unloading, thus avoiding the safety hazards of manual unloading.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
