[0002] The outer frame bracket for securing the battery is typically made of steel or aluminum alloy to ensure that the battery is securely fixed inside the vehicle's battery compartment, preventing damage from shaking or collisions during driving.

[0003] A search revealed that utility model patent CN213134539U discloses an extrusion die for aluminum profiles of a new energy vehicle battery pack outer frame. The die includes an upper die with flow-diverting holes inside. A lower die is fixedly mounted at the lower end of the upper die. A feed inlet is fixedly located at the center of the upper surface of the upper die. A die cavity is formed between the flow-diverting holes inside the upper die. An extrusion head is fixedly mounted inside the die cavity of the upper die. A positioning component is fixedly mounted inside the lower die. A welding chamber is formed on one side of the positioning component. The material supply of the flow-diverting holes needs to be arranged according to the shape of the profile cross-section, following the principle of supplying more when demand is high and less when demand is low, to reduce the lateral pressure on the die. The bridge widths of the flow-diverting holes are as consistent as possible to ensure uniform stress on the bridges and reduce flow obstruction of the aluminum rod, thereby effectively ensuring that the mechanical properties of the extruded profile from this new energy vehicle battery pack outer frame aluminum profile extrusion die meet the required standards.

[0004] However, current molding dies require guide pillars for guidance during mold closing. The repeated opening and closing of these guide pillars causes significant wear, affecting the accuracy of subsequent mold closing. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a molding die for fixing the outer frame bracket of a battery. This solves the problem that when using current molding dies, guide pillars are needed to guide the mold during mold closing. However, the repeated opening and closing of the guide pillars causes significant wear, which affects the accuracy of subsequent mold closing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a molding die for fixing a battery outer frame bracket, comprising a base and a top plate, wherein a lower die is fixedly installed at the upper end of the base, and an upper die is fixedly installed at the bottom of the top plate, the upper die and the lower die abutting against each other, a guide post one is fixedly connected to the bottom edge of the top plate, and a guide post two is fixedly installed at the upper edge of the base, the guide post two being slidably connected to the guide post one.

[0007] Preferably, the second guide post has a guide groove inside, and a guide rod is slidably connected to the inner side of the guide groove. A pad is fixedly connected to the top of the guide rod, and the pad is slidably connected inside the second guide post. The pad abuts against the first guide post. A sealing ring is embedded in the side of the pad, and the sealing ring is slidably connected to the inner wall of the second guide post. A spring is sleeved on the outer side of the guide rod, and a piston is fixedly connected to the bottom of the guide rod, and the piston is slidably connected to the inner side of the guide groove. After entering the second guide post through the first guide post, it applies a downward thrust to the pad, the guide rod, and the piston.

[0008] Preferably, one end of the first spring is fixedly connected to the pad, and the other end of the first spring is fixedly connected to the inner surface of the second guide post. By providing the first spring, the elastic force can be applied to the pad, which has an auxiliary resetting effect on the pad and the guide rod.

[0009] Preferably, the second guide post has an internal oil passage and an oil outlet, which are connected. The oil passage is connected to the guide groove.

[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 A mold for fixing a battery outer frame bracket includes a base 1 and a top plate 3. A lower mold 2 is fixedly installed on the upper end of the base 1, and an upper mold 4 is fixedly installed on the bottom of the top plate 3. The upper mold 4 and the lower mold 2 abut against each other. A guide post 5 is fixedly connected to the bottom edge of the top plate 3, and a guide post 6 is fixed to the upper edge of the base 1. The guide post 6 is slidably connected to the guide post 5.

[0022] Please see Figure 4The guide post 2 6 has a guide groove 61 inside. A guide rod 62 is slidably connected to the inner side of the guide groove 61. A pad 63 is fixedly connected to the top of the guide rod 62 and is slidably connected inside the guide post 2 6. The pad 63 abuts against the guide post 1 5. A sealing ring 64 is embedded in the side of the pad 63 and is slidably connected to the inner wall of the guide post 2 6. A spring 1 65 is sleeved on the outer side of the guide rod 62. A piston 66 is fixedly connected to the bottom of the guide rod 62 and is slidably connected to the inner side of the guide groove 61. After the guide post 1 5 enters the guide post 2 6, it will apply a downward thrust to the pad 63, the guide rod 62, and the piston 66. One end of the spring 1 65 is fixedly connected to the pad 63, and the other end of the spring 1 65 is fixedly connected to the inner surface of the guide post 2 6. The spring 1 65 can apply elastic force to the pad 63, which has an auxiliary restoring effect on the pad 63 and the guide rod 62.

[0023] Please see Figure 4-5 The guide post 6 has an internal oil passage 7 and an oil outlet 8, which are connected. The oil passage 7 is also connected to the guide groove 61. A threaded adjusting rod 9 is threadedly connected to the top of the guide post 6, extending into the inner side of the oil passage 7. A sliding rod 10 is slidably connected inside the threaded adjusting rod 9, and a float 11 is fixedly connected to the end of the sliding rod 10. The float 11 is slidably connected to the inner side of the oil passage 7, and its position corresponds to the oil outlet 8. When the lubricating oil in the oil passage 7 is compressed, it pushes the float 11 upwards, causing it to misalign with the oil outlet 8, thus releasing the lubricating oil and lubricating the connection between the guide post 5 and the guide post 6, ensuring smooth mold closing. A spring 13 is installed inside the threaded adjusting rod 9. One end of the spring 13 is fixedly connected to the sliding rod 10, and the other end is fixedly connected to the inner surface of the threaded adjusting rod 9. The spring 13 allows the reaction force to be applied to the float 11 via the slide rod 10. A guide block 12 is fixedly connected to the slide rod 10, and the guide block 12 is slidably connected to the threaded adjusting rod 9. The guide block 12 guides the relative sliding between the slide rod 10 and the threaded adjusting rod 9.

[0024] The specific implementation process of this utility model is as follows: In use, the upper mold 4 and the lower mold 2 are guided by the first guide post 5 and the second guide post 6 during mold closing. When the first guide post 5 is inserted into the second guide post 6, the first guide post 5 will apply a downward pushing force to the pad block 63. Subsequently, the pad block 63 drives the guide rod 62 and the piston 66 to slide in the guide groove 61. The piston 66 then applies pressure to the lubricating oil in the oil circuit 7 through the guide groove 61. The lubricating oil then pushes the float ball 11 upward. The float ball 11 then moves upward through the slide rod 10 and is misaligned with the oil outlet 8. In this way, the lubricating oil can overflow through the oil outlet 8 and lubricate the connection between the first guide post 5 and the second guide post 6, thereby reducing the wear of the two and ensuring smooth mold closing.
