Description

Technical Field

[0001] This utility model relates to the field of automotive structural component processing technology, and in particular to a casting and venting device for a die-casting mold for automotive structural components. Background Technology

[0002] Automotive structural components are essential parts of automobiles, including engines, chassis, bodies, electrical equipment, and tires. With the continuous improvement of economic levels, the die-casting industry has developed significantly. Pressure casting involves filling a mold cavity with molten metal under high pressure and high speed to form the desired shape. The die-casting mold is an indispensable tool in pressure casting. During the die-casting process, it is necessary to expel the gas from the mold cavity; failure to do so will affect the quality of the workpiece.

[0003] Chinese Patent CN218693748U discloses an exhaust device for an aluminum alloy die-casting mold, including a cooling box, a lower mold, and an exhaust groove. An upper mold is mounted on the top of the lower mold, and an exhaust groove is provided between the lower and upper molds. An exhaust port is installed on one side of the exhaust groove, and exhaust pipes are installed on both sides of the exhaust port. A cooling box is located at one end of each exhaust pipe. The cooling box has detachable structures at both ends of its top side, and an outlet pipe is installed on one side of its bottom. A filter structure is located at the top of the cooling box, and a cooling structure is located inside the cooling box. This invention utilizes a cavity within the cooling box into which cold water is added. When the high-temperature gas is exhausted, it exchanges heat with the cold water as it passes through the cooling pipes, achieving cooling and preventing the high-temperature gas from directly escaping and damaging items around the mold. After heat exchange, the cold water becomes hot water, which can be used for other purposes.

[0004] Existing venting devices for die-casting molds use heat exchange between cold water and high-temperature gas in the cooling tank to prevent damage to the mold. However, when the die-casting mold is working continuously, the cold water in the cooling tank is affected by the high-temperature gas, requiring the injection of new cooling water for reuse. This makes it difficult to continuously supply high-temperature gas for exchange. As a result, after the upper and lower molds complete the work of the first set, they need to stop and wait for the cold water to be injected. This operation reduces the processing efficiency of automotive structural parts and reduces the practicality of the venting device. Utility Model Content

[0023] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0024] Example 1

[0025] like Figure 1 - Figure 3 As shown, this utility model proposes a casting venting device for a die-casting mold of automotive structural parts, comprising: a support platform 1, a lower mold 2, an upper mold 3, an venting pipe 4, a cooling assembly, and three support frames 10; the cooling assembly is connected to the outlet end of the venting pipe 4; the cooling assembly includes a gas valve a5 and a connecting pipe 7; the gas valve a5 is connected to a cooling box a6; two connecting pipes 7 are provided and are respectively connected to both sides of the venting pipe 4, the two connecting pipes 7 are respectively connected to gas valves b8, and the gas valves b8 are respectively connected to two cooling boxes b9; three support frames 10 are provided and are respectively connected to the cooling box a6 and the two cooling boxes b9 for support; the internal structure of the cooling box a6 and the two cooling boxes b9 is identical, for continuous supply of high-temperature gas for heat exchange. After the cooling box a6 is used, the internal cooling temperature of the cooling chamber is affected, and then the high-temperature gas can be exchanged using any one of the cooling boxes b9, allowing the three cooling boxes to be used interchangeably, facilitating continuous supply of high-temperature gas exchange, enabling continuous operation of the venting device, improving the processing efficiency of automotive structural parts, and improving the performance of the casting venting device for die-casting molds of automotive structural parts.

[0026] Further explanation: A filter frame 601 is connected to the upper end of the inner wall of the cooling box a6. A filter plate is connected to the inner wall of the filter frame 601, and sliders are connected to both sides. The sliders are connected to slide grooves 602, which are located on both sides of the inner wall of the cooling box a6. A handle 608 is connected to one end of the filter frame 601, which passes through an opening, allowing the filter frame 601 to be movably connected inside the cooling box a6. The opening is located on one side of the cooling box a6. A partition 603 is connected inside the cooling box a6, and the partition 603 is connected to an air inlet pipe 604. The air inlet end of the air inlet pipe 604 is connected to the bottom of the filter plate, and the air outlet end passes through the partition 603 and connects to the cooling pipe 605. The air outlet end of the cooling pipe 605 is connected to the air outlet pipe 606, and the air outlet end of the air outlet pipe 606 passes through the cooling box a6 and connects to the outside. The gas is filtered by the filter plate to prevent the emission of toxic pollutants that could cause air pollution, thus conveniently improving the environmental friendliness of the casting venting device for automotive structural component die-casting molds.

[0027] To further explain, a tube 607 is connected inside the cooling box a6. The tube 607 is hollow inside, and its lower end passes through the cooling box a6 and connects to the outside and the water inlet pipe. It is used to cool the water inside the cooling box a6. After the high-temperature gas flows out through the cooling box, the temperature of the water inside the cooling box is affected. Cooling water is then added to the tube 607 through the water inlet pipe, which reduces the temperature change of the water inside the cooling box during use and facilitates improved secondary use efficiency.

[0028] Example 2

[0029] like Figure 1 and Figure 2 As shown, the present invention proposes a casting and venting device for a die-casting mold for automotive structural components. Based on the above embodiments, this embodiment also details the specific components of the lower mold 2, the upper mold 3, and the venting pipe 4, as well as their assembly method.

[0030] To further explain, the lower mold 2 is connected to the support platform 1; the lower mold 2 is connected to the upper mold 3 for die casting automotive structural parts; the exhaust pipe 4 is connected to the lower mold 2 and also to the upper mold 3; the exhaust pipe 4 is connected to the exhaust groove 401, and connecting grooves 402 are respectively connected to both sides of the exhaust groove 401, and the exhaust groove 401 and connecting grooves 402 are set on the lower mold 2 and the upper mold 3. The two ends of the upper mold 3 are connected to hydraulic cylinders and other vertical driving equipment, which facilitates the downward movement of the upper mold 3 and its connection with the lower mold 2 to achieve die casting of automotive structural parts. During the processing operation, the exhaust pipe 4, the exhaust groove 401, and the connecting groove 402 work together to discharge gas from the mold, thus improving the die casting quality of automotive structural parts.

[0031] The working principle of this utility model is as follows: The exhaust pipe 4 is connected to the exhaust channels 401 of the lower mold 2 and the upper mold 3. The exhaust channels 401 are connected to the connecting channel 402. When the lower mold 2 and the upper mold 3 are joined together, a large amount of gas that needs to be discharged is generated. The gas enters the exhaust pipe 4 through the connecting channel 402 and the exhaust channel 401. Then, by activating the gas valve a5, the gas enters the cooling box a6 and is finally discharged through the exhaust pipe 606. During use, cold water is added to the cooling box a6. When the gas enters the cooling pipe 605 inside the cooling box a6, it can exchange heat with the cold water, cooling the gas. After the exchange of quantities, the cold water becomes hot water, which can be used for other purposes. However, when the cooling box a6 is used, the temperature of the cooling pipe 605 inside the cooling box a6 cavity is affected, making it inconvenient to continuously coordinate the venting of the lower mold 2 and the upper mold 3. Therefore, the connecting pipe 7 on either side of the venting pipe 4 is used. The connecting pipe 7 is connected to the cooling box b9 through the gas valve b8. The gas valve b8 is activated, so that the gas is delivered into the cooling box b9. The high-temperature gas exchange between the cooling box b9 and the cooling box a6 is the same, achieving the exchange of the three cooling boxes for operation. This facilitates the improvement of the die-casting processing efficiency of automotive structural parts and the use of the venting device for the casting mold of automotive structural parts.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
