Mold surface TD treatment raw material pre-mixing stirring apparatus

Abstract

The invention relates to the field of mold manufacturing, particularly to a mold surface TD treatment raw material pre-mixing stirring apparatus, which comprises a wide-mouth pre-mixing barrel for holding a raw material, wherein a material inlet and a material outlet are respectively arranged in the side walls of the pre-mixing barrel, a sealing cover is movably embedded on the inner edge of the wide mouth of the pre-mixing barrel, the upper end surface of the sealing cover is provided with a frustum type rack, the upper end of the rack is provided with a flat end surface, the upper end of a rotation shaft is rotatably installed in the flat end surface of the rack, the lower end of the rotation shaft penetrates through the sealing cover, and extends into the pre-mixing barrel, a pluralityof pre-mixing paddle blades are uniformly arranged on the outer edge of the lower end portion of the rotation shaft at intervals, and the upper end portion of the rotation shaft is connected to the output end of a power output device.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a premixing and stirring device for TD treatment raw materials on the mold surface. Background technique [0002] Surface TD treatment is an important process in mold processing, and the effect of surface TD treatment directly affects the quality of the mold. [0003] The existing mold surface TD treatment device generally includes a premixing device, but in the process of use, there are certain problems in the existing premixing device. The existing premixing device includes a tank body, and a stirring device is installed in the tank body. During use, since most of the materials used are borax molten salt, borax molten salt will accumulate in the tank under the influence of impurities and temperature after long-term use, resulting in blockage of the connecting pipe with the surface treatment device, while other parts attached to the stirring device The borax molten salt on the...
