The invention belongs to the technical field of additive manufacturing, particularly belongs to the technical field of sand mould casting 3D printing, and relates to a sand clearing device for a sandmould 3D printing model. The sand clearing device comprises a worktable, an inclined rotating table and a movable gas gun, wherein the inclined rotating table is arranged on the worktable; the movablegas gun is movably arranged above the inclined rotating table; movement of the movable gas gun is controlled by a crossed type motion mechanism; the crossed type motion mechanism is arranged on a motion platform defined by four guide rails by two guide rails which are connected with each other in a crossing manner; a gas gun mounting platform is arranged at an intersection part of the two crossedguide rails; a plurality of gas gun spray nozzles are formed in the gas gun mounting platform and are connected with an external gas source through pipelines. According to the sand clearing device disclosed by the invention, an automatic sand clearing operation of the sand mould 3D printing model can be realized, the efficiency is high, and environmental pollution is little.
Description
technical field [0001] The invention belongs to the technical field of additive manufacturing, in particular to the field of 3D printing of sand mold casting, and relates to a sand cleaning device for a sand mold 3D printing model. Background technique [0002] With the gradual development of industrial technology, the demand for complex parts and personalized customization has become stronger and stronger, and the application of additive manufacturing technology has emerged. Additive manufacturing technology has become the most popular technology in the 21st century due to its fast speed, high efficiency and intelligent operation. 3D printing technology is a branch of additive manufacturing. Using 3D printing technology to print sand molds or sand molds for casting can realize the rapid production of complex parts, shorten the research and development cycle, reduce research and development costs, and improve research and development efficiency. However, the 3D printed sand...
