Abstract

The invention discloses a novel casting mold testing device. The novel casting mold testing device comprises a casting mold, a thermocouple and a data collector. The casting mold is provided with a cavity, a liquid inlet channel, a dead head and a pouring system, the liquid inlet channel is communicated with the bottom of the cavity, the cavity is provided with a plurality of sub-cavities, the apertures of the sub-cavities are gradually increased, the dead head is communicated with the sub-cavity with the largest aperture, the pouring system is communicated with the liquid inlet channel, and a cavity is formed between the pouring system and the cavity. The thermocouple is installed on the casting mold and extends into the sub-cavity, and the input end of the data collector is connected with the thermocouple. The invention further discloses a control method of the novel casting mold test device for shrinkage porosity. According to the novel casting mold test device and the shrinkage porosity control method thereof, a single influence factor, namely the cooling rate, can be generated in the solidification process of a metal material, so that the influence rule of the cooling rate on the shrinkage porosity morphology, size and distribution can be researched, and the shrinkage porosity defect can be regulated and controlled in practical application.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a novel casting mold test device and a method for controlling shrinkage porosity. Background technique [0002] During the casting process, high-temperature liquid metal flows to fill the mold cavity. When the temperature is lowered to room temperature, a casting depending on the shape of the casting mold cavity is obtained. During the cooling and solidification process of liquid metal, due to the influence of various factors, casting defects such as pores, shrinkage porosity, shrinkage cavities, inclusions, and cold shuts will occur, which will deteriorate the mechanical properties of the material. [0003] Among them, shrinkage porosity depends largely on the solidification range, volume shrinkage and process conditions of the alloy. From the perspective of alloy solidification characteristics, the wider the solidification interval of the alloy, the greater the volume shrinka...
