Further, the first pouring cup is made of steel, and the second pouring cup is made of precoated sand.
Furthermore, a stop block is fixedly arranged on the outer side of the second pouring cup, and the second pouring cup is clamped in the through hole of the upper die through the stop block.
Furthermore, the vertical section of the upper channel is in a trapezoid shape with a wide upper part and a narrow lower part, the vertical section of the lower channel is in a trapezoid shape with a narrow upper part and a wide lower part, and the filter screen is arranged at the joint of the upper channel and the lower channel.
Furthermore, the stop block is annular and is coaxially arranged with the second pouring basin.
Further, the middle part of the first pouring cup is provided with a middle channel, and the middle channel is communicated with the upper channel.
Further, the diameter of the filter screen is larger than that of the lower end of the upper channel, and the diameter of the filter screen is smaller than that of the lower end of the upper channel.
The utility model has the advantages that: the utility model discloses a split type concatenation pouring basin, first pouring basin forms with the concatenation of second pouring basin, and the first pouring basin that is located the upper end is steel pouring basin, and the second pouring basin that is located the lower extreme adopts the sand mould structure, places the filter screen in second pouring basin. The utility model discloses saved tectorial membrane sand cost, when the sand mould volume reduces, mould composing quantity increases, and curing time shortens, and preparation efficiency improves. The sand mould volume reduces, and is reduced than former sand matter pouring basin degree of depth, puts into the filter screen degree of difficulty and also reduces, puts into efficiency improvement.
