The invention discloses a vacuum degreasing sintering furnace. The furnace comprises a furnace body, and a thermal insulation cylinder and thermal insulation doors which are arranged inside the furnace body, wherein the thermal insulation doors are arranged at the two ends of the thermal insulation cylinder, and a heating body is arranged inside the thermal insulation cylinder; furnace doors are hinged to the two ends of the furnace body, any one of the two furnace doors is provided with a cooling system, a gas inlet pipe is arranged on the furnace body and is communicated with a gas source; the furnace body is connected with a graphite guide rail through a stand column, the graphite guide rail is used for supporting and conveying a work bin and is provided with a plurality of rolling needle bearings, and the work bin can move on the graphite guide rail; a gas inlet valve and a cooling hole are arranged on the work bin, and the cooling hole can be closed by a movable upper cover on thefurnace body; a gas exhaust flange is arranged at the lower part of the furnace body, is communicated with a vacuum pump, and is connected with a lower degreasing pipe and an upper degreasing pipe insequence, and the upper degreasing pipe is driven by a lifting mechanism to move in the lower degreasing pipe and is communicated or separated from a gas discharging hole of the work bin. The vacuumdegreasing sintering furnace has the advantage of high production efficiency.
