Novel combined water cooling die

Abstract

The invention discloses a new type combined water-cooling mold, which mainly includes seamless steel pipes, side channels, side channel sealing plates, water inlets, water outlets and movable parts. The seamless steel pipes are arranged flush from bottom to top and welded as a whole, the two ends of the seamless steel pipe extend into the cavity of the side waterway and form a rectangular frame with the side waterway, the contact position between the seamless steel pipe and the side waterway is fully welded and sealed, and the side waterway sealing plate seals the two sides The water channel is sealed and welded, and the bottom and top of the side channel sealing plate are respectively provided with water inlets and water outlets, and the water barriers are alternately welded left and right between every 3-5 seamless steel pipes in the horizontal direction in the two side channel cavities. The movable part is detachably arranged at the bottom of the rectangular frame body. The invention uses a movable and replaceable template bottom to realize the replacement of the damaged bottom plate, and other parts can continue to be used, thereby improving the maintenance efficiency and reducing the mold use cost.

Description

technical field [0001] The invention relates to a water-cooled mold, in particular to a water-cooled mold for cooling molten steel or alloy liquid in a vacuum melting furnace, an open melting furnace, and the like. It is widely used in the cooling and forming of various metal liquids such as hydrogen storage alloys, vanadium aluminum alloys, magnetic material alloys, and intermediate alloys, and can realize rapid cooling of high-temperature metal liquids. Background technique [0002] At present, vacuum melting furnaces, open melting furnaces and other casting molten steel or alloy liquid cooling molds generally use water-cooled discs, or sealed and fixed water-cooled molds. These two methods have poor thermal conductivity. On the low side. Therefore, prolonging the cooling time is usually used to achieve the required furnace temperature, and the production cycle of the equipment is relatively long. Usually, the bottom of the water-cooled mold is in contact with the alloy ...

AI Technical Summary

Problems solved by technology

Usually, the bottom of the water-cooled mold is in contact with the alloy liquid first, and the bottom of the mold is most likely to corrode. After the bottom of the mold is corroded, the entire mold must be scrapped.

Therefore, the existing water-cooled mold has long cooling time, low equipment production capacity, too much loose metal material, low product qualification rate, low mold service life, and increased maintenance costs.
