发明名称 Method of manufacturing dies and molds by melting-spray
摘要 A method of manufacturing die and mold by melting-spray relates to a method of manufacturing die and mold used for plastic or metal shaping, in which there is no need for the operating procedure of replicating a melting-sprayed prototype from a prototype or from a rubber die which is reproduced from the prototype. The present invention includes the following steps: (1) directly manufacturing the melting-sprayed prototype; (2) forming a melting-spray layer on the surface of the melting-sprayed prototype; (3) reinforcing the melting-spray layer; and (4) removing the melting-sprayed prototype and then obtaining the die or mold. With this invention, the fast manufacturing speed, the low cost and the improved precision are obtained, and the existent operating procedure for manufacturing die and mold by melting-spray is shortened, thereby it is suitable for manufacturing die and mold used for plastic or metal shaping.
