A vacuum diffusion welding mold, comprising a mold body (1), characterized in that: the mold body (1) is composed of an upper plate (11) and a lower plate (12), and a snake is provided on the upper plate (11) A curved hot oil flow channel (2) and a straight cooling flow channel (3), the lower plate (12) is provided with a matching hot oil flow channel (2) and a cooling flow channel (3), The upper plate (11) and the lower plate (12) are fixed by screws. 2. A vacuum diffusion welding mold according to claim 1, characterized in that: a cooling water transport inlet (5) and a cooling water transport outlet (4) are provided on one side of the upper plate (11), and The cooling water inlet (5) and the cooling water outlet (4) are communicated with both ends of the cooling channel (3). 3. A vacuum diffusion welding mold according to claim 1, characterized in that: the upper plate (11) is provided with a cooling water transport inlet (5) and a cooling water transport outlet (4) adjacent to a A hot oil outlet (6) and a hot oil inlet (7) are arranged on the side, and the hot oil outlet (6) and the hot oil inlet (7) are communicated with the hot oil flow channel (2).

Molds, various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In a nutshell, a mold is a tool used to make a shaped item, this tool is made up of various parts, and different molds are made up of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The current mold has insufficient welding and high welding temperature. To this end, a vacuum diffusion welding mold is proposed. The purpose is to provide a vacuum diffusion welding mold to solve the above-mentioned problems in the background art. , provides the following technical scheme: a vacuum diffusion welding mold, including a mold body, the mold body is composed of an upper plate and a lower plate, the upper plate is provided with a serpentine curved hot oil flow channel and a linear cooling A flow channel, the lower plate is provided with a matching hot oil flow channel and a cooling flow channel, and the upper plate and the lower plate are fixed by screws. Preferably, a cooling water transport inlet and a cooling water transport outlet are provided on one side of the upper plate, and the cooling water transport inlet and the cooling water transport outlet communicate with both ends of the cooling channel. [Preferably, a hot oil outlet and a hot oil inlet are provided on the side of the upper plate adjacent to the cooling water inlet and the cooling water outlet, and the hot oil outlet and the hot oil inlet are connected to the hot oil flow channel. connected. Technical effects and advantages of the present invention: the vacuum diffusion welding mold product has the advantages of high welding strength, small deformation, seamlessness, etc., and can manufacture large-sized molds and related products; vacuum diffusion welding is a vacuum or protective atmosphere. The material is heated to 0.5~0.8 times of its thermodynamic melting point, and through a certain pressure and holding time, the microscopic contact points on the surface of the material to be welded will undergo creep deformation to achieve large-area close contact, and further use of atomic diffusion, Recrystallization and other metallurgical processes to achieve precise and reliable welding of welded materials
