A stamping type automotive hinge production mold

Abstract

This utility model relates to the field of automotive accessory processing technology and discloses a stamping-type automotive hinge production mold, including a lower mold base. A lower mold is fixedly installed in the middle of the upper surface of the lower mold base. Guide rods are fixedly installed on both sides of the upper surface of the lower mold base, and an upper mold base is fixedly installed at one end of each guide rod. This stamping-type automotive hinge production mold, through the coordinated arrangement of a guide channel, a water tank, a water pump, a liquid inlet pipe, a return water pipe, a semiconductor cooling plate, and a heat sink, allows the water pump to deliver coolant from the water tank to the guide channel via the liquid inlet pipe, thereby cooling the lower mold.

Description

Technical Field

[0001] This utility model relates to the field of automotive accessory processing technology, specifically a stamping automotive hinge production mold. Background Technology

[0002] Automotive hinge mounting plates are typically installed on the left and right sides of a car frame to mount the left and right doors, allowing the doors to hinge to the frame for easy opening. During manufacturing, these plates require punching using stamping dies. After stamping, a coating is applied to the surface to improve performance, reduce corrosion, and extend service life.

[0003] Most existing stamping automotive hinge production dies cannot be cooled down, causing the die temperature to rise with processing time. However, excessively high die temperature will reduce the hardness of the die material, affecting the wear resistance and strength of the die. Furthermore, the current dies cannot quickly eject the hinge from the die during use. Therefore, this utility model provides a stamping automotive hinge production die. Utility Model Content

[0010] (III) Beneficial Effects Compared with the prior art, this utility model provides a stamping type automotive hinge production mold, which has the following beneficial effects: This stamping-type automotive hinge production mold, through the coordinated arrangement of a guide channel, water tank, water pump, inlet pipe, return pipe, semiconductor cooling plate, and heat sink, allows for efficient operation. During use, the water pump delivers coolant from the water tank to the guide channel via the inlet pipe, cooling the lower mold. The coolant is then returned to the water tank via the return pipe, where the semiconductor cooling plate further cools the tank, thus effectively cooling the mold and ensuring its wear resistance and strength. The electric push rod, connecting plate, and ejector pin, combined with the design of an electric push rod, pushes the ejector pin to eject the hinge workpiece from the mold during stamping, thereby improving production efficiency.

Detailed Implementation

[0013] 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.

[0014] Please see Figure 1-2This utility model provides a technical solution: It includes a lower mold base 1, a lower mold 2 fixedly mounted on the middle of the upper surface of the lower mold base 1, guide rods 3 fixedly mounted on both sides of the lower mold 2 on the upper surface of the lower mold base 1, an upper mold base 4 fixedly mounted at one end of each guide rod 3, a sliding plate 5 slidably connected to the surface of each guide rod 3, an upper mold 6 fixedly mounted at the bottom of the sliding plate 5, and a drive cylinder 7 fixedly mounted on the upper surface of the lower mold base 1. One end of the drive cylinder 7 slidably passes through the upper mold base 4 and is fixedly connected to the sliding plate 5. Both sides of the interior of mold 2 are provided with connecting guide channels 8. A water tank 9 is fixedly installed on the upper surface of the upper mold base 4 on one side of the drive cylinder 7. A water pump 10 is fixedly installed on one side of the water tank 9. The output end of the water pump 10 is fixedly connected to the water inlet of the guide channel 8 through a liquid delivery pipe 11. The water outlet of the guide channel 8 is fixedly connected to the water tank 9 through a return water pipe 12. A semiconductor cooling plate 13 is fixedly installed at the bottom of the water tank 9. A heat sink 14 is fixedly installed at the bottom of the semiconductor cooling plate 13. The flow channels 8, water tank 9, and water pump 10 are connected to the guide channel 8. The coordinated arrangement of the infusion pipe 11, return pipe 12, semiconductor cooling plate 13, and heat sink 14 allows the water pump 10 to be activated during use. The water pump 10 delivers the coolant from the water tank 9 through the infusion pipe 11 to the guide channel 8, thereby cooling the lower mold 2. The coolant is then returned to the water tank 9 through the return pipe 12, and then cooled by the semiconductor cooling plate 13. This effectively cools the mold while ensuring its wear resistance and strength. The lower mold 2 has an internal opening... An installation groove 15 is provided, and an electric push rod 16 is fixed inside the installation groove 15. A connecting plate 17 is fixedly installed at one end of the electric push rod 16, and an ejector pin 18 is fixedly installed on the upper surface of the connecting plate 17. Through the cooperation of the electric push rod 16, the connecting plate 17 and the ejector pin 18, when the hinge workpiece is stamped, the electric push rod 16 pushes the ejector pin 18 to push the workpiece out of the mold, thereby improving production efficiency. A spring 19 is sleeved on the outer wall surface of the guide rod 3, and a slider 20 is installed at one end of the spring 19.

[0015] In summary, this stamping automotive hinge production mold, through the coordinated arrangement of the guide channel 8, water tank 9, water pump 10, liquid inlet pipe 11, return water pipe 12, semiconductor cooling plate 13, and heat dissipation plate 14, allows the water pump 10 to deliver coolant from the water tank 9 to the guide channel 8 via the liquid inlet pipe 11, thereby cooling the lower mold 2. Subsequently, the coolant in the guide channel 8 is returned to the water tank 9 via the return water pipe 12, and then the semiconductor cooling plate 13 cools the water tank 9, thus cooling the mold and effectively ensuring its wear resistance and strength. Through the coordinated arrangement of the electric push rod 16, connecting plate 17, and ejector pin 18, when the hinge workpiece is stamped, the electric push rod 16 pushes the ejector pin 18 to eject the workpiece from the mold, thereby improving production efficiency.
