无模铸型制造技术是以树脂砂为成型材料,利用快速成型技术的离散/堆积成型原理,对三维CAD实体模型进行分层切片处理,得到不同高度截面层的信息,采用截面扫描、喷射固化工艺,直接获得树脂砂铸型或铸造模具的一种方法。在复杂铸件快速制造的实际应用中,无模铸型制造技术表现出造型材料易得、制造时间短、制造成本低、铸件质量好等优点,体现了快速敏捷制造的优势,也为快速成形技术在铸造中的应用开辟了一个新领域。
The technology of moldless manufacturing is based on the resin sand as the forming material. By using the principle of discrete molding and rapid prototyping, the 3D CAD solid model is sliced and sliced to get the information of cross-section layers. The cross-section scanning, Process, a direct access to resin sand casting mold or casting a method. In the practical application of rapid manufacturing of complex castings, die-less manufacturing technology shows the advantages of easy-to-obtain molding materials, short manufacturing time, low manufacturing cost and good casting quality, which shows the advantages of rapid agile manufacturing and rapid prototyping technology The application of foundry opened up a new area.
