A preparation equipment for powder injection molding feed

Abstract

The invention discloses powder injection molding feeding manufacturing equipment which comprises a kneading device, an extruding device and a grain cutting device. A discharge outlet of the kneading device is communicated with a barrel inlet end of the extruding device, the grain cutting device is connected to a barrel outlet end of the extruding device, and powder materials are kneaded by the kneading device, then are directly fed into the extruding device, pass the extruding device and then are directly fed into the grain cutting device to be subjected to hot-cutting air-cooled granulation. The powder injection molding feeding manufacturing equipment for realizing powder injection molding feeding manufacturing effects has the advantages that large-scale continuous operation with high production efficiency can be carried out; the hot-state materials can be directly fed into follow-up machining links, accordingly, reheating temperature rise required by granulation procedures can be reduced, and energy consumption can be greatly decreased; labor can be saved, the efficacy of the equipment can be improved, the productivity can be enhanced, and the production cost can be reduced; crushing procedures which are carried out after intermediate cooling and solidifying can be reduced, dust can be prevented in material crushing procedures, and accordingly operation environments can be improved.

Description

technical field [0001] The invention relates to the technical field of powder injection molding, in particular to a device for preparing feed materials for powder injection molding. Background technique [0002] Powder injection molding mainly includes metal powder injection molding (Metal Powder Injection Molding, referred to as MIM) and ceramic powder injection molding (Ceramic Powder Injection Molding, referred to as CIM), the traditional powder injection molding feed preparation process is: batching→mixing → crushing → extrusion granulation, and the equipment used includes at least two or more of kneaders (or internal mixers, high-speed mixers), crushers, screw extruders, and granulators, and each equipment is independent Working, transferring materials between multiple devices in each process not only reduces production efficiency, but also easily causes material pollution during the transfer process, which leads to unfavorable factors such as changes in the physical an...
