Description
Technical field
The utility model relates to valve manufacture industry, about a kind of centrifugal casting ball device, using which solves
When centrifugal casting steel ball body, the easy sticking mould of molten steel dismantles difficult problem, rationally determines centrifugal casting technological parameter, starts centrifuge
Turntable is driven, casting ball device high speed rotation is driven, water cooling switch is opened, infuses molten steel from cast gate, after the fast cooling solidification of molten steel,
The upper and lower hemisphere mold shut down in stripping device couples fastener, takes out sphere casting, and appearance forms smooth even, high-quality,
It is easy to operate, high production efficiency.
Background technique
Valve manufacture industry is all centrifugal casting to the sphere in ball valve body, when routine uses punching block, punching block heat resistance
It is low, it cracks vulnerable to thermal oxide modification, molten steel is easily Nian Jie with punching block, and General fasteners are because heated deformed threads, intensity decline, from pouring
Molten steel is infused on mouthful, after the fast cooling solidification of molten steel, the upper and lower hemisphere mold connection fastener shut down in stripping device is difficult, and low efficiency,
Large labor intensity.
Summary of the invention
The purpose of the utility model is to provide a kind of centrifugal casting ball devices, using which solves centrifugal casting steel
When sphere, the easy sticking mould of molten steel dismantles difficult problem, realizes fast mounting-dismounting, improve working efficiency, reduces labor intensity.
Technical solutions of the utility model are as follows: its structure fastens sphere with soket head cap screw (8) on centrifuge turntable (1)
Lower semisphere mold (2), couples episphere mold (3) with bolt (7) on lower semisphere mold (2), and episphere mold is used on (3)
Hex screw (5) fixed cast gate pressing plate (6) composition, at sphere casting (4) after being poured molten steel；Lower semisphere mold (2), episphere
Mold (3) its material is high-strength ductile cast iron；Connection hex screw (5), bolt (7), soket head cap screw (8) its material are
Martensitic stain less steel.
The positive effect of the present invention is:
When centrifugal casting steel ball body, the easy sticking mould of molten steel dismantles difficult problem, realizes fast mounting-dismounting, improves working efficiency, drop
Low labor intensity, mold heat resistance is high, indeformable, does not crack, long service life.

Specific embodiment
Sphere lower semisphere mold 2 is fastened with soket head cap screw 8 on centrifuge turntable 1, in lower semisphere mold 2
Upper bolt 7 couples episphere mold 3, is formed on episphere mould 3 with the fixed cast gate pressing plate 6 of hex screw 5, rationally really
Determine centrifugal casting technological parameter, starting centrifuge drives turntable 1, drives centrifugal casting present apparatus high speed rotation, opens water cooling and opens
It closes, injects molten steel from cast gate, after the fast cooling solidification of molten steel, shut down episphere mold 3, the lower semisphere mold 2 in stripping device
Connecting bolt takes out sphere casting 4, is put into interior, and storage is examined in impeller blasting processing.
