The invention provides a casting pouring system and a casting production method. The casting pouring system comprises a sand box, a bottom quartz sand layer arranged in the sand box, precoated sand molds overlaid on the bottom quartz sand layer, grid screen pieces located besides the inner wall in the sand box, a side quartz sand layer arranged between the grid screen piece and the precoated sand molds in a filling manner, a pressing bar detachably connected with the sand box and an adjusting block located between the pressing bar and the top of the precoated sand molds. According to the casting production method, the precoated sand molds are overlaid on the bottom quartz sand layer in the sand box one by one, and a precoated sand molten iron stopper is arranged in the bottom end of a spure of the precoated sand mold on the lowest layer; when the precoated sand molds are overlaid to be close to the upper surface of the sand box, the four grid screen pieces are placed all around the inner walls of the sand box correspondingly, the gap between the precoated sand molds and the grid screen pieces is filled with quartz sand with the mesh number being 20-40, and the quartz sand is compacted; and one end of the pressing bar is placed in a fixed pressing buckle, the gap adjusting block is placed in a gap between the pressing bar and the precoated sand molds, a movable pressing buckle presses the other end of the pressing bar, and the movable pressing buckle is fixed to the sand box.
Description
technical field [0001] The invention relates to the field of casting technology, in particular to a pouring system for small castings and a production method for small castings. Background technique [0002] Generally, the production method of small castings is out-of-box molding or leaky mold molding. These molding methods occupy a large area, consume a lot of molding materials, use more casings and weights, and have complicated processes; and small castings are light in weight and single The demand for molten iron for piece products is small, and the pouring must be subcontracted, and the pouring time is relatively long, which is likely to cause spheroidization of the spheroidized molten iron, gestation decline, and unstable product quality. [0003] CN1951596 disclosed a kind of heat-coated sand stack casting process on April 25, 2007, including steps such as mold making, molding sand preparation, core mold making, core mold forming, mold closing, pouring, sand cleaning, ...
