Quick powder forming method for parts

The invention belongs to the technical field of part forming, and particularly relates to a quick powder forming method for parts. The method comprises the following four steps: mixing and granulating, crushing and screening, preparing a green body and demolding and sintering. Compared with the prior art, the technical scheme provided by the invention has the following advantages that a mixture of a powder material and an adhesive can form a product green body with a smooth surface and few internal pores through a mode of matching a silicon rubber mold with heating and vacuumizing, a plurality of products used as samples can be quickly obtained through simple procedures such as demolding and sintering, and a long-period mold machining process and large-scale trial production equipment are not needed. 本发明属于零部件成型技术领域，具体涉及一种零部件快速粉末成型方法。所述方法包括混炼造粒，粉碎筛分，制作生坯和脱模烧结4个步骤。本发明提供的技术方案与现有技术相比具有如下优势：本发明提供的技术方案通过硅橡胶模具配合加热抽真空的方式使得粉末材料与粘合剂的混合物可以成型表面光滑与内部孔隙少的产品生坯，再通过脱模烧结等简单工序就可以快速获得作为试样使用的多个产品，无需周期冗长的模具加工过程和使用大型试产设备。
