A kind of turbine case casting mould, including casting, die holder and with the die holder matching closed die, the die holder
For the casting between the die holder and mold, the cast(ing) surface has several casting boss, the mold and institute
The contact surface for stating casting boss is provided with chill, and chill inner chamber forming surface is identical with casting boss outer surface, the chill system
Into left and right sides opposite opened, if there is dried layer chill piece, the table that the chill piece is in contact with the casting boss per side chill
Face is provided with lines；The upper surface of the die holder is provided with multiple raised and grooves, each raised surface, die holder upper surface and
Each groove floor declines in staged successively, forms stopper slot between raised, spacing preiection is formed between groove.
On the basis of above-mentioned technical proposal, the utility model can also improve as follows：
Further, the side of the upper surface of the die holder is provided with first raised and the second projection, in the upper of the die holder
The opposite side on surface is provided with the first groove and the second groove, and stopper slot, the first groove are formed between the first projection and the second projection
And second form spacing preiection between groove.
Further, along being looked perpendicular to the upper surface direction of die holder, the stopper slot is identical with spacing preiection shape.
Further, the upper surface of the die holder is provided with locating dowel, and the mold is provided with to match with the locating dowel
Locating slot.
Further, the positioning convex being engaged with the stopper slot and spacing preiection and positioning are respectively equipped with mold
Groove.
Further, there is two layers of chill piece per side chill.
The beneficial effects of the utility model are compared with prior art：
1st, the utility model is provided with multiple raised and grooves in the upper surface of die holder, and stopper slot is formed between raised, casts
Liquid is guided in the multiple workpiece of the upper surface of die holder flowing casting by the stopper slot, will not everywhere scatter, limit is formed between groove
Position is raised, ensures accurate positioning.The locating dowel of die holder and the locating slot of mold can interfix, and be further ensured that positioning is accurate
Really.
2nd, for the utility model by being provided with chill in the contact surface of mold and the casting boss, left and right two is made in chill
Side opposite opened, chill inner chamber have forming surface identical with casting boss outer surface, casting boss is in chill and largely coat
State, contact area is big, and casting boss cooling velocity is accelerated, while has Multi-layer iron chill piece, chill piece and casting per side chill
The surface that boss is in contact is provided with lines, further increases contact area, can strengthen chilling action so that cast product can reach
Solidify simultaneously, and eliminate issuable fire check and cracking at thermal center.It is very convenient clear during cleaning and chill is opposite opened
Except recovery.
