Abstract
The invention discloses a compressed spring support column welding mould of a hermetically sealed refrigeration compressor. The mould comprises an upper mould seat and a lower mould seat. The upper mould seat comprises a connection plate and an upper electrode. The lower mould seat comprises lower electrodes, an electrode seat and a base plate. A lower connection plate is arranged on the upper surface of the base plate and is fixedly connected with the base plate. A limit column is fixedly installed on the lower connection plate and vertically stretches upward out of the lower connection plate. The electrode seat and the limit column form interference fit through a limit hole. A compressed spring is arranged between the electrode seat and the lower connection plate and is sleeved on the limit column. By means of the technical scheme, the surfaces of four lower electrodes are coplanar before the upper mould moves downwards to conduct welding, welding quality of the support column is improved, and invasion of welding slag is avoided. The mould is simple and compact in integral structure, effectively reduces working time in the mould debugging and maintenance process in the later period, improves working efficiency, prolongs service life of the mould, and simultaneously shortens manufacture period.
