Description

technical field [0001] The invention relates to the technical field of production of honeycomb ceramics, in particular to a combined extrusion molding processing tool of honeycomb ceramics and an implementation method thereof. Background technique [0002] Honeycomb ceramics is a new type of ceramic product with a honeycomb-like structure. It was first used in the purification of exhaust gas from small cars. The wider the area, the more promising the development prospects. At present, the industry mainly adopts the method of extruding ceramic materials in honeycomb processing tooling to produce honeycomb ceramics. [0003] However, the traditional extrusion molding processing tooling generally adopts an integral structure, which is directly installed on the extrusion molding machine through fasteners. During the disassembly process, it will inevitably cause certain wear and tear on the fasteners and hole grooves, which affects the tightness. The matching accuracy between t...

Problems solved by technology

[0003] However, the traditional extrusion molding processing tooling generally adopts an integral structure, which is directly installed on the extrusion molding machine through fasteners. During the disassembly process, it will inevitably cause certain wear and tear on the fasteners and hole grooves, which affects the tightness. The matching accuracy between the firmware and the hole groove reduces the connection stability between the processing tool and the extrusion molding machine, and the replacement needs to be disassembled as a whole, which makes maintenance difficult, time-consuming and laborious, and increases the maintenance cost of the processing tool. At the same time, most of the processing tools do not have a cooling function, and the hot-melt ceramic materials can only be slowly solidified by air cooling, which inevitably affects the forming efficiency of honeycomb ceramics
