Embodiment 1

[0044] like Figure 1-2As shown, the technical solutions of this embodiment and the comparative embodiment are basically the same, the difference is that: the position of the riser 2 is set on the inner side of the outermost flange 3 of the exhaust manifold, the riser neck 4 is arranged laterally, and the riser 2 The bottom is connected with the cavity of the outermost hot spot of the casting through the riser neck 4 . This setting moves the riser 2 that originally occupied the outer space of the flange plate 3 to the inner side of the sand box, and the amount of sand eaten is increased from about 30mm to 100mm, which effectively ensures the safe amount of sand eaten.

[0045] In this embodiment, the riser 2 is arranged on the rear side of the hot joint position on the edge of the sand box, and is connected to the rear side of the flange 3 through the L-shaped riser neck 4, thereby increasing the amount of sand eaten to 100mm, which can make the original Type 1 / mold is increa...

Embodiment 2

[0047] The technical solutions of this embodiment and Embodiment 1 are basically the same, the difference is that the molding sand includes the following raw materials in parts by weight: 95% of quartz sand, 4% of zircon sand, 0.5% of polyacrylamide, 3% of starch, 5% of coal powder, and 5% of lignin fiber , Kaolin 1, aluminum powder 0.2, vegetable oil 0.4.

[0048] After the molding sand is mixed, the moisture content is measured, and the moisture content is adjusted by measures such as drying, ventilation or spraying and watering. The final moisture content is controlled at 3.5% by weight to ensure the compactability, fluidity and air permeability of the molding sand. Finally, the air permeability of the prepared molding sand was measured to be 140, and the hot-wet tensile strength was 25Kpa. During the casting process, the molding sand structure is stable, there are no sand hole defects, and the surface of the casting is smooth and does not stick to the sand.

Embodiment 3

[0050] The technical solutions of this embodiment and Embodiment 2 are basically the same, the difference being that the molding sand includes the following raw materials in parts by weight: 85% of quartz sand, 6% of zircon sand, 0.8% of polyacrylamide, 5% of starch, 3% of coal powder, and 7% of lignin fiber , kaolin 2, aluminum powder 0.5, vegetable oil 0.6. The final moisture content is controlled at 4.5% by weight to ensure the compactability, fluidity and air permeability of the molding sand. The prepared molding sand has an air permeability of 100 and a hot and wet tensile strength of 28kpa. During the casting process, the molding sand structure is stable, there are no sand hole defects, and the surface of the casting is smooth and does not stick to the sand.

Abstract

The invention discloses a casting mold for increasing mold thickness. The casting mold comprises a sand box, molding sand, a pouring cup and a riser, wherein the riser is arranged at the rear side ofthe hot joint position at the edge of the sand box, so that an original mold with one cavity is changed into a mold with two cavities, or the mold with two cavities is changed into a mold with four cavities; the safe mold thickness is sufficiently ensured; the running-out phenomenon of a casting during casting process will not occur; and the safe pouring without running-out is ensured while the utilization of the sand box is improved.

Description

technical field [0001] The invention relates to a casting device, in particular to a casting mold with increased sand consumption. Background technique [0002] The sand intake refers to the thickness of the molding sand from the inner wall of the sandbox to the outer wall of the cavity, and the thickness of the molding sand from the top or bottom of the sandbox to the mold cavity. [0003] When casting thin-walled steel castings, due to the thin wall thickness, the liquid steel temperature drops rapidly, it is difficult to fill the cavity, and it is prone to insufficient pouring and cold shut. Now it is generally in production, which can avoid insufficient pouring and cold shut defects. At the same time, The process control is stable and the yield is high. However, the special sand-covered iron mold production line needs to use the sand box matching the production line, but sometimes the size of the casting does not match the size of the sand box. When the foundry product...
