Description

Technical Field

[0001] This utility model relates to the technical field of vacuum negative pressure casting equipment, and more precisely to a vacuum negative pressure casting trough liquid level control device. Background Technology

[0002] Vacuum negative pressure casting is a process for casting aluminum alloy round ingots. It utilizes vacuum technology to create negative pressure within a mold cavity, guiding the molten aluminum alloy into the cavity. This process effectively removes gas from the mold cavity, thereby eliminating or significantly reducing gas and dissolved gases within the die-cast parts. This significantly improves the mechanical properties and surface quality of the die-cast parts, making it an advanced die-casting technology.

[0003] Vacuum negative pressure casting systems incorporate a runner level control system. This system monitors, regulates, and adjusts the molten metal level in the runner during the vacuum negative pressure casting process, ensuring a stable level throughout the filling and crystallization stages. This guarantees the stability of the casting process and the quality of the castings. Existing runner level control systems are categorized by their operating principles, including ultrasonic, radar, float-type, and hydrostatic systems. However, these systems generally suffer from low measurement accuracy, poor environmental adaptability, and low durability. These issues can negatively impact the performance and lifespan of aluminum alloy castings and may also lead to splashing or leakage of molten aluminum due to poor level control, compromising production safety. Therefore, existing vacuum negative pressure casting runner level control systems are insufficient to meet the current production requirements of vacuum negative pressure casting.

[0004] In summary, there is a need in this field to improve the existing vacuum negative pressure casting channel level control system in order to enhance detection accuracy, system stability and reliability, and production safety. Utility Model Content

[0022] Specifically, the support assembly includes a first support 11 and a second support 12. Both ends of the flow channel assembly 20 are connected to the first support 11 and the second support 12, respectively. The laser liquid level detection device 4 is installed in conjunction with the first support 11. One end of the flow channel assembly 20 connected to the first support 11 is connected to the casting zone flow channel, and the other end of the flow channel assembly 20 connected to the second support 12 is connected to the liquid storage area. Several baffle assemblies are installed in conjunction with the first support 11 and the second support 12, respectively. During operation, the baffle assemblies change the on / off state of the flow channel assembly 20, adjusting the flow rate of the molten metal entering the casting zone flow channel.

[0023] The flow channel assembly 20 is segmented, with fixed flow channels 21 at both ends. The two fixed flow channels 21 are connected by a flexible flow channel 22. The flexible flow channel 22 is connected to a lifting flow channel 23 on its side. The ends of the two fixed flow channels 21 away from the flexible flow channel 22 have a first docking plate 201 and a second docking plate 202, respectively, which are connected to the casting area flow channel and the liquid storage area.

The liquid storage servo cylinder is installed in conjunction with the second bracket 12, and the liquid storage baffle is installed on the output end of the liquid storage servo cylinder. When the liquid level rises to a certain level, the liquid storage baffle automatically opens under the drive of the liquid storage servo motor, allowing excess liquid to flow into the storage area; when needed, this liquid can be redirected back into the flow tank to ensure the continuous operation of the casting process.
