Abstract

The invention discloses a small-specification horizontal machine PCD enamelling mold, and relates to the field of high-speed horizontal machine enamelling molds and powder metallurgy processes. The small-specification horizontal machine PCD enamelling mold is characterized in that a PCD composite sheet is cut into a needed shape through laser, ultrasonic shaping and polishing are carried out to obtain a needed hole pattern and size, and a mold core is obtained; and a mold seat is fixed through a graphite mold sleeve, the mold core is placed in a mold body, sintering raw materials are added the a space between the mold seat and the mold core, then the mold body is placed on a hot pressing sintering machine to be sintered, the mold core is fixed to the center of the mold seat through a powder metallurgy process in a hot pressing sintering mode, and the enamelling mold is obtained. According to the small-specification horizontal machine PCD enamelling mold, the PCD composite sheet material is used for replacing a traditional tungsten steel material, the wear resistance is obviously improved, and the surface roughness is obviously reduced, so that the situation that in the enameled wire enamelling process, mold clamping and wire breaking are prone to happen is improved; the mold seat and the mold core are tightly connected through the sintering process, so that the problems that quality of the enameled wires is poor and defective products are produced due to rejection of the mold caused by the fact that the mold core can fall off after a long time or paint leaks from joints due to the fact that the mold core is abraded and consumed quickly are solved.

Description

technical field [0001] The invention relates to the field of high-speed horizontal machine painting molds and powder metallurgy technology, in particular to a small-sized horizontal machine PCD painting mold. Background technique [0002] The enameled wire painting process involves high-speed horizontal machine painting molds. At present, the mold cores used in high-speed vertical machines are tungsten steel cores. The disadvantages are: the wear ratio of tungsten steel is small, and the wear and consumption are fast during the production process. Often, the die jamming rate is high, the amount of wire waste is large, the parallelism of the paint film is poor, the production efficiency of the workers is low, time-consuming, and power-consuming, etc.; [0003] Therefore, in order to improve production efficiency, reduce energy consumption, and improve product quality, the present invention proposes a small-sized horizontal machine PCD painting mold to solve the above problems...
