Core, external mold are cylindric.
Described base is provided with annular boss, and the external mold bottom is positioned at the outer ring of boss, and the core bottom is positioned at the inner ring of boss.
Described forward and backward mould and left and right matrix top are equipped with the withdrawing pattern screw.
Four outer walls of described core central block are equipped with pattern draft and for inwardly shrinking from bottom to up, pattern draft is 5 °; The external mold inwall also is provided with pattern draft, and the top end diameter of external mold endoporus is less than external mold endoporus bottom diameter.
Described external mold and core are contour.
The groove of the outer surface of described core be round thread groove or the annular groove that is arranged above and below or square thread groove or along the border oval groove spaced apart up and down or uniform sphere pit.
The beneficial effects of the utility model are: 1, mould structure is flexible, can adapt to the making of various special-shaped cylinder jacket sand mold linings; 2, the raising of Mould Machining precision can guarantee sand mold lining precision, thereby guarantees foundry goods outward appearance and precision; 3, four faces of core central block from the bottom to the upper end all have pattern draft, are easy to carry out withdrawing pattern; 4, very high by mould production sand mold lining efficient.
