| titleOfInvention | Mould-free manufacturing method of dry type clay sand casting mould |
| abstract | A method for manufacturing a dry clay sand casting mould without a mould comprises the steps of carrying out three-dimensional modeling according to the shape of a casting to be cast, completing casting process, casting mould and casting mould parting design, and respectively designing and processing sand mould cores after the casting mould is parted. And (2) making a sand blank, prefabricating one or more sand boxes for standby according to the size of the sand core of the sand mold, fully stirring and mixing water, a binder, additives, molding sand and the like by using a sand mixer according to a certain proportion, placing the mixed green sand into the sand box, using a sand pestle tool to tamp the green sand, using a scraper to strike off the green sand, placing the pestle tool into drying equipment for drying, and drying to obtain one or more sand blanks. And (3) using a die-free casting precision forming machine for machining and forming, wherein the machining process comprises sand blank milling, cavity milling, residual milling and contour milling of equal height. If multi-face machining is required, a five-axis die-less casting precision forming machine can be used for fixed-axis machining and five-axis machining, and multi-face machining is carried out by turning over a sand block. The mold-free manufacture of the dry clay mold can be realized. |
