Hub die-casting molten aluminum anti-overflow device

Abstract

The invention discloses a hub die-casting molten aluminum anti-overflow device and belongs to the field of hub manufacturing. Through the hub die-casting molten aluminum anti-overflow device, when aluminum overflow does not occur, an anti-overflow aluminum wire surrounds a die. When aluminum overflow occurs, molten aluminum breaks an insulated skin of the anti-overflow aluminum wire to be in contact with an internal lead wire, a 0V voltage on the ground is connected with the internal lead wire and transmitted to an aluminum overflow input contact, the 0V voltage of the aluminum overflow inputcontact and a 24V voltage of a common terminal form a pressure drop loop, and the aluminum overflow input contact is effectively triggered through a low level. Under the action of input signals, the aluminum overflow input contact of a PLC module outputs a signal to the signal input end of a furnace body exhaust valve, the furnace body exhaust valve is turned on, and the pressure in a furnace bodyis rapidly relieved. The hub die-casting molten aluminum anti-overflow device greatly reduces the jet energy and jet range of molten aluminum and effectively guarantees the safety of working staff. Meanwhile, the hub die-casting molten aluminum anti-overflow device effectively protects peripheral devices against damage due to aluminum overflow. Thus, the hub die-casting molten aluminum anti-overflow device has the characteristics of guaranteeing the safety of working staff and equipment safety.

Description

technical field [0001] The invention relates to the field of wheel hub manufacturing, in particular to a wheel hub die-casting anti-running aluminum liquid device. Background technique [0002] In the manufacture of aluminum alloy wheels for automobiles, the most widely used is the die-casting process. The die-casting process is to press the liquid aluminum in the furnace body into the wheel hub mold, and then shape the wheel hub after air cooling and water cooling. Specifically, such as figure 1 As shown, the mold is erected and fixed above the furnace body. There is a riser pipe between the upper mouth of the furnace body filled with aluminum liquid and the lower mouth of the mould, and the lower part of the riser pipe passes through the furnace and extends to the bottom of the furnace body. And leave a certain distance from the bottom surface of the furnace body, and the furnace body adopts a sealed structure design. When working, the inside of the furnace body is injec...

AI Technical Summary

Problems solved by technology

The temperature of the molten aluminum during die-casting the wheel hub is as high as 700 degrees Celsius. If it splashes on the skin of the personnel, it will cause severe burns and burns, which seriously threatens the safety of the staff. In addition, the molten aluminum sprayed out will also cause serious damage to the peripheral equipment of the mold.
