Integrated device of hot injection molding technology

Abstract

The invention provides an integrated device of the hot injection molding technology. The integrated device of the hot injection molding technology comprises a stirring material preparing system, a die casting system and a machine shell. The stirring material preparing system comprises a stirring tank, a stirring machine and a lifting machine. A tank body of the stirring tank is arranged to have an inner layer and an outer layer, and a cavity is formed between the outer layer of tank body and the inner layer of tank body. The cavity is filled with heat conduction silicone oil, and a heater and a temperature sensor are arranged. A discharging opening is further formed in the bottom of the stirring tank. The die casting system comprises a material liquid pipeline, a material outlet, a support and a pressing device. The material liquid pipeline is arranged between the discharging opening and the material outlet. The material outlet is formed in the upper surface of the machine shell and is further formed in the central axis of the support. The support is arranged on the upper surface of the machine shell. The pressing device is arranged in the center of a beam of the support and corresponds to the material outlet. By means of the integrated device of the hot injection molding technology, it is ensured that the temperature of material liquid is uniform through oil bath heating of the stirring tank and a heating belt on the material liquid pipeline, and in addition, the automation degree of the device is relatively high.

Description

technical field [0001] The invention relates to the technical field of ceramic hot die casting equipment, in particular to an integrated hot die casting molding process equipment. Background technique [0002] Hot die-casting has been widely used in the production of industrial ceramics. It is a commonly used molding method, and it has obvious advantages in the production of small, complex and special-shaped ceramic products. The basic principle of hot pressing molding or hot pressing injection molding is to use the characteristics of paraffin wax to melt when heated and to solidify when cooled, to uniformly mix non-plastic barren ceramic powder with hot paraffin liquid to form a flowable slurry. Pour it into a metal mold to form, cool down and wait for the wax slurry to solidify, then demould and take out the formed body. The green body is properly trimmed, embedded in an adsorbent and heated for dewaxing treatment, and then the dewaxed green body is sintered into the fina...

AI Technical Summary

Problems solved by technology

[0003] 1. The degree of automation is not high, the workers work hard, and the production efficiency is low

[0004] 2. The uneven mixing of ceramic powder and paraffin will cause air bubbles in the green body

[0005] 3. Unbalanced temperature control during material liquid and injection, which affects the die-casting effect
