The invention discloses a split forming nozzle for a carbon electrode extruder, and relates to the technical field of extruder accessories, in particular to a split forming nozzle with a replaceable nozzle core and for the carbon electrode extruder. A nozzle core of the split forming nozzle is a rotary body, and a linear section and a curve section are machined on the inner surface of the nozzle core; the nozzle core and a nozzle sleeve are in transition fit to be assembled into the forming nozzle; a heat-conducting oil spiral channel A and a heat-conducting oil spiral channel B are arranged in the mold nozzle; a sealing assembly is assembled between the nozzle core and the nozzle sleeve; a groove is formed in the bottom of the nozzle sleeve, and the forming nozzle can be pulled out and replaced through a matched forming nozzle pulling-out device; an electric heater is mounted at an outlet of the nozzle sleeve through a screw and is tightly attached to the forming nozzle; and one end of a temperature sensor is provided with threads and screwed into the nozzle sleeve. According to the technical scheme, the problems that in the prior art, the inner wall of a forming nozzle is abraded quickly, the overall replacement cost is high, heat-conducting oil is prone to leaking to cause safety accidents, the temperature of an outlet of the forming nozzle cannot be controlled, the product quality is poor, the head lowering phenomenon of the forming nozzle affects the quality of a green body, and the nozzle is inconvenient to replace and hoist are solved.
Description
technical field [0001] The invention relates to a split die for a carbon electrode extruder, and relates to the technical field of extruder accessories, in particular to a split die with replaceable nozzle cores for a carbon electrode extruder. Background technique [0002] At present, the existing carbon electrode extrusion machine nozzle is an integral nozzle, and the outside of the nozzle body is designed with a heat transfer oil channel, an insulation layer and a temperature sensor. [0003] The existing carbon electrode extruder nozzles have the following problems: [0004] 1. The inner wall of the nozzle wears quickly, the wear is serious, and the cost of spare parts is high; [0005] 2. The heat transfer oil is easy to leak, which is prone to safety accidents; [0006] 3. There is no temperature control measure at the outlet of the nozzle, and the product quality is poor; [0007] 4. The mold mouth lacks effective support, and it is easy to "bow its head", which af...
