Once shaping mould for electrode contact blank

The utility model discloses a one-shot forming mould for an electrode contact blank, comprising an upper mould plate and a lower mould plate which are integrated through a locking device to form a hollow cavity which are penetrative from top and bottom; the inner part of the hollow cavity is provided with an upper mould pressing head and a lower mould pressing head which are matched with the hollow cavity and can move up and down in the hollow cavity; the upper mould plate and the lower mould plate are combined with the upper mould pressing head and the lower mould pressing head to form a truncated cone-shaped hollow cavity whose radius of both ends is smaller than the middle radius. After adopting the technical proposal, the mould of the utility model can make the graphite electrode contact blank formed by extruding at one time; not only the processing method has high rate of the finished products, but also the extraction rate of the finished product electrode contact per ton is more than 85%; in this way, the cost of the utility model is reduced, and energy consumption is economized in the production process; the produced electrode contact has the characteristics of high density, high compressive strength and transverse strength, low resistivity, etc.
