Abstract
The utility model relates to a molten metal level position sensor in a casting mold. The molten metal level position sensor in the casting mold comprises a sensing temperature measuring point, a built-in thermocouple, an insulating ceramic layer, a stainless steel outer shell, a fixing screw and two high temperature resistant connecting wires. The stainless steel outer shell is externally connected to the end of a screw rod of the fixing screw, the built-in thermocouple is arranged in the stainless steel outer shell, the insulating ceramic layer is arranged between the inner wall of the stainless steel outer shell and the built-in thermocouple, the end, away from the fixing screw, of the built-in thermocouple is externally connected to the sensing temperature measuring point, and a through hole is formed in the fixing screw. According to the molten metal level position sensor in the casting mold, the position where molten aluminum arrives is detected through several molten metal level position sensing and composite sensing devices embedded in assigned positions in the mold, and information is fed back to a digitized pressurization system, and automatic adjustment is carried out through a digital control system to meet the requirements of process conditions.
