Abstract

The invention provides a fluidity measuring device and measuring method based on a serpentine flow channel. The device comprises: at least one mold assembly, which is arranged on a rack, and comprisesan upper mold plate and a lower mold plate, wherein the upper mold plate is arranged on the lower mold plate, the serpentine flow channel is formed in the face, close to the upper mold plate, of thelower mold plate, a flow channel opening is formed in the upper mold plate, and the flow channel opening is communicated with a pouring inlet of the serpentine flow channel; a pouring cup, which is arranged on the upper mold plate, is communicated with the pouring inlet through the flow channel opening; and a heating device, which is arranged on the rack. According to the fluidity measuring deviceand measuring method based on the serpentine flow channel, a straight flow channel is changed into the serpentine flow channel, the length of the flow channel is increased under the condition that the size of the mold assembly is not changed, the upper mold plate is made of a transparent material, and the experiment phenomenon can be conveniently observed in the testing process.

Description

technical field [0001] The invention relates to the technical field of investment casting teaching, in particular to a fluidity measuring device and a measuring method based on a serpentine flow channel. Background technique [0002] Casting is one of the basic processes of modern basic machinery manufacturing industry. Fluidity is one of the casting properties of the alloy, which directly affects the filling ability of the liquid alloy. The better the fluidity of the alloy, the stronger the filling ability, the more clear-cut, thin-walled and complex castings can be poured out, and it is also conducive to the floating and discharge of inclusions and gases and the shrinkage of the solidification process; and the poor fluidity It is difficult for the alloy to fill the cavity, and the filling ability is poor, and defects such as insufficient pouring, cold shut, pores, and slag inclusions are prone to occur. [0003] With the development of technology, investment casting tech...
