Description
Technical Field
The utility model belongs to the technical field of the casting technique and specifically relates to a shedder of riser ring is used in wind-powered electricity generation product casting.
Background
Most of wind power product castings are large in size, and pouring gates and air holes involved in the casting process are more, used riser rings are more, and used riser rings are also larger. The riser ring can delay the solidification speed of the riser neck when in use, so that slag floating above the casting can be discharged out of the cavity as much as possible. In the manufacturing process of the riser ring, because the sand consumption is large, the pressure in the pressing process is large, and the bonding between the molding sand and the cavity of the riser ring is firm. The traditional manual demoulding is difficult, the manual forced demoulding is difficult, the operation difficulty is high, and the riser ring is easy to damage.
Disclosure of Invention
In order to solve the above-mentioned problem that exists among the prior art, the utility model provides a wind-powered electricity generation product casting is with stripper of riser ring, concrete technical scheme is as follows:
a stripper of a riser ring for casting a wind power product comprises a rack and a riser ring mold; the riser ring mould is arranged on the rack and is provided with a plurality of identical cavities, and a core rod is arranged in the center of each cavity; the cavity is a circular truncated cone-shaped cavity with a large upper part and a small lower part, and the core rod is a circular truncated cone-shaped columnar structure with a small upper part and a large lower part; the cavity and the core rod are of a coaxial structure;
the top surface of the cavity is open, and the bottom plate of the cavity and the side wall of the cavity are of a separation structure;
the bottom surface of the bottom plate of each cavity is connected with the same lifting support, the bottom of the lifting support is connected with a piston rod of an air cylinder, and a cylinder body of the air cylinder is connected to the rack;
and air springs are connected between each bottom plate and the lifting support, the air inlet ends of the air springs are respectively connected with a compressed air source through pulse inflation electromagnetic valves, and the air outlet ends of the air springs are respectively connected with a pressure release valve.
When the air spring is used, after the riser ring is formed, the pulse air inflation electromagnetic valve is started, and the air spring vibrates in the vertical direction under the action of the pressure release valve. Because the material of air spring is elastic rubber, and the air pressure unit effort comes from compressed air moreover, and air spring is more gentle to the riser ring application of force on it, is difficult for bringing the damage to riser ring structure. Through the vibration of short time, can be shaken loose and break away from the back between riser ring and the mould, restart cylinder, jacking riser ring. The air cylinder and the air spring can adopt the same set of compressed air source.
When the engineering is realized, the bottom of the core rod is connected to the dead head ring die through a plurality of cross rods, the top end of each cross rod is connected with the core rod, and the cross rods are symmetrical around the axis of the core rod; the bottom plate is in a ring shape, and the core rod penetrates through the hollow part of the ring; the bottom surface of the bottom plate is connected to the air spring through a plurality of vertical rods, and each vertical rod is arranged in a hollow space between the adjacent cross rods. Interference between the connection mechanisms is avoided.
The bottom surface of lifting support is connected with many bearing diagonal poles, and the bottom of each bearing diagonal pole is connected in the piston rod of cylinder, and the top of each bearing diagonal pole is connected in lifting support's bottom surface, and the axis of air spring passes the top that corresponds the bearing diagonal pole. Each supports the down tube of down tube direct transmission holding power and gives every riser ring below, avoids the adverse effect that structural component deformation brought.
Each cavity is symmetrical about the same axis.
This shedder of riser ring is used in wind-powered electricity generation product casting is applicable to the drawing of patterns of great volume riser ring very much, adopts the vibration mode that is soft more, when making things convenient for the drawing of patterns, also is difficult for damaging the riser ring, improves the surface quality of riser ring.
