Mould surface TD (Thermal Diffusion) treatment pre-mixing production device

Abstract

The invention relates to the field of mould manufacturing, in particular to a mould surface TD (Thermal Diffusion) treatment pre-mixing production device. The mould surface TD treatment pre-mixing production device comprises a premixing device and a surface TD treatment device; the premixing device comprises a wide mouth premixing tank; a premixing sealing cover is movably embedded into the inneredge of a wide mouth which is formed in the wide mouth premixing tank; a machine frame is mounted on the upper end surface of the premixing sealing cover; the upper end of a rotating shaft is rotatably mounted in a flat end surface which is formed on the machine frame; the lower end of the rotating shaft penetrates through the premixing sealing cover and extends into the wide mouth premixing tank;the upper end part of the rotating shaft is connected with an output end of a power output device; the mould surface TD treatment pre-mixing production device comprises a hollow tank body which is provided with an opening; at least two air inlets are uniformly formed in the side wall of the hollow tank body at an interval; an air inlet is mounted in each of the air inlets; an exhaust end of eachair inlet pipe is positioned at the bottom of the inner side of the hollow tank body; an air inlet end of each air inlet pipe communicates with an exhaust end of an air compressing pump.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a premix production device for mold surface TD treatment. 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 and a surface TD treatment device, but in the process of use, there are certain problems in the existing premixing device. The existing premixing device includes a tank body. A stirring device is installed. During use, since most of the materials used are borax molten salt, the 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. And other borax molten salts attached to the surface of the stirring device will affect...

Problems solved by technology

[0003] The existing mold surface TD treatment device generally includes a premixing device and a surface TD treatment 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 the tank body A stirring device is installed. During use, since most of the materials used are borax molten salt, the 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. However, other borax molten salt attached to the surface of the stirring device will affect the speed of the stirring device, resulting in insufficient premixing

[0004] And above-mentioned insufficient premixed borax molten salt enters in the downstream surface TD treatment device, because the effect of gravity the distribution of borax molten salt and special medium must not be uniform enough, it is likely to cause uneven process of metal carbide diffusion coating, thus Affect the quality of the mold, resulting in an increase in the defective rate
