Problems solved by technology

If the casting is taken out too early, the internal stress of the casting will increase, and the risk of cracking will easily occur; if the casting is taken out too late, although it is beneficial to the stress release of the casting, it will greatly reduce the turnover of the production sand box and affect the production efficiency

Abstract

The invention discloses an internal temperature monitoring device for a heavy casting in the cooling process. The internal temperature monitoring device for the heavy casting in the cooling process comprises a temperature controller, a thermocouple arranged at the temperature measuring point and a compensating wire which is connected with the thermocouple and the temperature controller, and the thermocouple is pre-buried in molding sand in a sand box. According to the internal temperature monitoring device for the heavy casting in the cooling process, the thermocouple and external equipment are used for measuring the temperature of the heavy casting in the cooling process, the temperature change of the casting in the cooling process is known, the reasonable taking time of the casting is determined, and therefore the deformation and stress problems of the casting can be effectively controlled, and the turnover efficiency of the production sand box is improved. The invention further discloses an internal temperature monitoring method for the heavy casting in the cooling process.

Description

technical field [0001] The invention belongs to the technical field of full mold casting, in particular, the invention relates to a monitoring device and a monitoring method for the internal temperature of a large casting cooling process. Background technique [0002] At present, the domestic solid mold casting industry still uses traditional empirical methods to determine the take-out time of castings, and the take-out time of castings is calculated according to the weight of the castings. Due to the different structures and wall thicknesses of automobile stamping dies, the temperature of the castings varies greatly when they are taken out. If the casting is taken out too early, the internal stress of the casting will increase, and the risk of cracking will easily occur; if the casting is taken out too late, although it is beneficial to the stress release of the casting, it will greatly reduce the turnover of the production sand box and affect the production efficiency.
