[0011] Preferably, the movable mold base and the second baffle are fixedly installed by bolts, and the fixed die core is located inside the movable mold base. Through the detachable installation of the movable mold base and the second baffle, it is convenient to replace the fixed die core. Different shapes or sizes of tubular parts may require different fixed die cores. When the fixed die core is damaged or needs to be repaired, the fixed die core can be quickly replaced, which can reduce the downtime without replacing the entire mold, improve the production efficiency, and thus improve the flexibility of the production line.

[0012] Preferably, a molding cavity is formed between the fixed mold base, the movable mold base and the fixed mold core. Different-sized molding cavities can be formed according to the replacement of the fixed mold core, improving the flexibility of the production line.

[0013] Preferably, a fixed plate is fixedly installed at the top of the base. An electric push rod is fixedly installed on one side of the fixed plate.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] Please refer to Figures 1-3 , the present utility model provides a technical solution: a die-casting mold structure for a tubular part, including a base 1 and a replacement component. A fixed mold base 2 is fixedly installed on the top of the base 1. The replacement component is arranged on the base 1. The replacement component includes a movable mold base 4, a second baffle 5 and a fixed mold core 6. A second baffle 5 is arranged on one side of the movable mold base 4, and a fixed mold core 6 is fixedly installed on one side of the second baffle 5.

[0026] Furthermore, a first baffle 3 is arranged on one side of the fixed mold base 2. The fixed mold base 2 and the first baffle 3 are fixedly installed by bolts, which is convenient for disassembling the first baffle 3, thereby facilitating the cleaning of the inside of the fixed mold base 2.

[0027] Furthermore, the movable mold base 4 and the second baffle 5 are fixedly installed by bolts. The fixed mold core 6 is located inside the movable mold base 4. Through the detachable installation of the movable mold base 4 and the second baffle 5, it is convenient to replace the fixed mold core 6. Tubular parts of different shapes or sizes may require different fixed mold cores 6. When the fixed mold core 6 is damaged or needs to be repaired, the ability to quickly replace the fixed mold core 6 can reduce downtime without having to replace the entire mold, improving production efficiency and thus increasing the flexibility of the production line.

[0028] Moreover, a forming cavity 7 is formed between the fixed mold base 2, the movable mold base 4 and the fixed mold core 6. Different-sized forming cavities 7 can be formed according to the replacement of the fixed mold core 6, improving the flexibility of the production line.

[0029] Most importantly, a fixing plate 11 is fixedly installed at the top of the base 1. An electric push rod 8 is fixedly installed on one side of the fixing plate 11. The free end of the electric push rod 8 is fixedly installed with a connecting plate 9. The connecting plate 9 is arranged on the other side of the second baffle 5 and is fixedly installed by bolts. A plurality of ejector pins 10 are fixedly installed on one side of the fixing plate 11 and are distributed in an annular array. A through hole is opened on one side of the second baffle 5. The other end of the ejector pin 10 is located in the through hole. By controlling the contraction of the electric push rod 8, the movable mold base 4 is driven to move to the left, so that the ejector pin 10 ejects the formed mold. The fixed installation of the ejector pin 10 facilitates the ejection operation of the formed mold when the movable mold base 4 moves, avoiding manual removal.

[0030] Secondly, a pouring gate 12 is opened between the fixed mold base 2 and the movable mold base 4. Cooling grooves 13 are opened inside both the fixed mold base 2 and the movable mold base 4. During the die-casting process, the inside of the mold will be affected by high temperature. After pouring is completed, cooling water is conveyed into the cooling grooves 13 to cool the poured mold. By opening the cooling grooves 13 inside the fixed mold base 2 and the movable mold base 4, a cooling medium can be introduced to effectively reduce the mold temperature and keep the mold within a suitable working temperature range, making the die-casting cycle shorter, thus improving production efficiency. At the same time, it can help avoid quality problems such as deformation or cracks in the tubular parts during die-casting. A stable mold temperature helps ensure the consistency of the part size and shape, improving product quality.

[0031] Secondly, the other end of the fixed mold core 6 is in contact with one side of the first baffle 3, facilitating the subsequent die-casting of tubular parts.

[0032] Working principle: When in use, start the electric push rod 8. The push rod of the electric push rod 8 pushes the second baffle 5 and the movable mold base 4 to move towards the fixed mold base 2, so that the movable mold base 4 fits with the fixed mold base 2. Then, pour into the inside of the molding cavity 7 through the pouring port 12. After pouring is completed, convey cooling water into the inside of the cooling tank 13 to cool the poured mold. Then, start the electric push rod 8, and drive the movable mold base 4 to move to the left by controlling the contraction of the electric push rod 8, so that the ejector pin 10 ejects the molded mold, and the molded mold can be taken out.
