注射模随形冷却水道的真空扩散焊工艺研究

Investigation on vacuum diffusion welding technology of CCC for injection mould

以电动机后盖注射模随形冷却水道的设计和加工为研究对象,结合机械加工和真空扩散焊技术,对随形冷却水道的制造工艺进行研究。结果表明,采用真空扩散焊技术焊接的随形冷却水道镶件的焊缝两侧的组织均匀,焊缝硬度与母材硬度接近,未出现波动现象,焊接质量良好。

Taking the design and processing of conformal cooling channel （CCC） for the injection mould of the motor rear cover as the research object, the manufacture process of the CCC was studied by combining the mechanical processing technology with the vacuum diffusion welding technology. The results showed that the weld structure was uniformity on both weld sides of the waterway inserts by means of vacuum diffusion welding. Besides the hardness of the weld was close to the base material, and there was no fluctuations phenomenon.
