Abstract

The invention discloses an injection molding method of a ceramic die core of a wire drawing die. The injection molding method comprises the following steps: (a) selecting and preparing materials; (b) roughly mixing; (c) finely mixing; and (d) carrying out injection molding. The invention discloses the injection molding method of the ceramic die core of the wire drawing die. The molding method is reasonably-arranged in procedures and moderate in cost; the technological parameters of the die core in the aspects of selection and preparation, material mixing, injection molding and the like are properly set and the method is convenient to implement, so that the molded die core has good and stable comprehensive mechanical properties; and especially, the performances in the aspects of toughness and thermal stability are prominent, so that the use performance of the ceramic die core is improved.

Description

technical field [0001] The invention relates to a molding method of a core of a wire drawing die, in particular to an injection molding method of a core of a ceramic wire drawing die, and belongs to the technical field of mold manufacturing. Background technique [0002] The wire drawing die is a tool for stretching metal wires (rods). Its body is mainly composed of a steel sleeve and a core. The steel sleeve is usually made of stainless steel. The core can be made of hard alloy, alloy steel, natural diamond, and artificial diamond. , ceramics and other materials. [0003] The shape of the wire drawing die core is relatively complex, the size is small, and the forming precision is high. Ceramic material has good wear resistance, high temperature resistance, corrosion resistance and high strength, and the preparation cost is moderate, but the current ceramic mold core is still insufficient in terms of thermal shock resistance and toughness, and it is difficult to process aft...
