Abstract
The invention discloses a multi-contact sand pressing mechanism. The multi-contact sand pressing mechanism comprises a sand box; an auxiliary framework is arranged on the inner wall of the sand box; a casting mold piece is arranged at the bottom in the sand box; the sand box is filled with casting sand; a pressing plate is arranged over the sand box; downward-pressing contacts distributed at equal intervals are arranged on the lower surface of the pressing plate; the lower end portions of the downward-pressing contacts right face the casting sand in the sand box; the upper end portions of the downward-pressing contacts are connected with driving rods; the driving rods extend out of the upper surface of the pressing plate and are connected with driving cylinders correspondingly; the driving cylinders control the corresponding downward-pressing contacts to press downwards the casting sand through the driving rods; and the driving cylinders are fixed to the upper surface of the pressing plate. According to the multi-contact sand pressing mechanism, the cylinders are adopted to control the multiple contacts to automatically press downwards the sand for casting, force borne by the casting sand is uniform, the forming quality of a sand core is guaranteed, time and labor are saved, the structure is simple, implementation is easy, and good application prospects are achieved.
