the following detailed description will be made in conjunction with embodiments of the present invention with reference to the accompanying drawings.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, a casting model structure for reducing product air holes and slag hole defects comprises a pouring cup 1, wherein an outlet at the bottom of the pouring cup 1 is connected with a vertical pouring gate 3, a horizontal slag filter 2 is arranged in the middle of the pouring cup 1, the bottoms and the two sides of the vertical pouring gate 3 are respectively connected with a lapping plate 7, the lapping plate 7 is far away from one side of the vertical pouring gate 3 and is connected with a horizontal cross pouring gate 6, the top of the cross pouring gate 6 is vertically connected with a plurality of water inlet plates 4, the cross pouring gate 6 is respectively connected with a casting 10 and a riser 8 through the water inlet plates 4, the riser 8 is close to one side of the casting 10 and is provided with a riser neck 9, the riser 8 is connected with the casting 10 through the riser neck 9, and the tail end of the cross pouring gate 6 is connected with an overflow block 5.

Particularly, the upper part of the vertical section of the pouring cup 1 is trapezoidal, the lower part of the vertical section of the pouring cup is triangular, and the slag filter 2 is positioned between the trapezoidal section and the triangular section of the pouring cup 1.

In particular, the filter residue sheet 2 is double-layered.

In particular, the overflow block 5 has a trapezoidal cross section.
