Method and equipment for manufacturing gradient material mould

Abstract

The invention relates to a method and equipment for manufacturing a gradient material mould. By adopting the technology of outer-field compounding, molding, forcible temperature control, sequential growth, and whole welding forming, a double metal gradient material is subjected to in-situ alloying, and the gradient material mould is manufactured in a near net way; and in the method, an electromagnetic stirring action, an electromagnetic metallurgical action and an ultrasonic welding action are produced, the large-volume welding pool liquid metal solidification process is comprehensively controlled, and the gradient material mould is manufactured by matching a high-speed wire feed system, a mould forcible temperature control system, a near net forcible sequential growth whole forming system, and an in-situ alloying gradient material. The equipment is formed by integrating and combining an electromagnetic welding system, an ultrasonic welding system, and an efficient welding system. By the method and the equipment for quickly manufacturing the gradient material mould by a non-layered welding structure in a low-cost way, a manufacturing period is reduced, production efficiency is improved, and the high reliability and the long service life of the mould are guaranteed.
