Description
Technical Field
The utility model relates to a rising head technical field especially relates to a K6 waist circle heat preservation rising head for bolster.
Background
The locomotive bolster casting is a low alloy steel casting, the weight of the casting is 450 kg, the average wall thickness is 20-30 mm, the casting temperature is 1580 ℃, and the casting is a typical complex-structure, thin-wall and load-bearing casting. The hot junction part of the swing bolster casting is provided with a circular arc-shaped bulge, while a blind riser which is commonly used at present is flat, so that a large gap is generated between the riser and a tool, extra sand filling and repairing work is needed, the riser is frequently displaced during molding, and the production efficiency is reduced; when the swing bolster casting is poured, the generated gas amount is large, the aperture of an exhaust hole formed in a common blind riser is small, and the gas cannot be exhausted in time.
SUMMERY OF THE UTILITY MODEL
To among the prior art scheme locomotive swing bolster foundry goods often take place the displacement and exhaust hole can not exhaust problem rapidly when the molding, the utility model provides a K6 waist circle shape heat preservation rising head for swing bolster.
The utility model provides a following technical scheme: the waist-round heat-insulation riser for the K6 swing bolster comprises a side wall, an inner cavity formed by the side wall in a surrounding mode and a top cover arranged at the top of the side wall, wherein an exhaust port is formed in the top cover, the inner wall of the side wall is perpendicular to the bottom surface of the riser, a crescent positioning notch is formed in one end, far away from the top cover, of the side wall, and the area of the exhaust port on the top cover accounts for 30% -50%.
Preferably, the projections of the side wall and the exhaust port on the top cover are all in a waist circle shape and are coaxial.
Preferably, the bottom of the side wall is provided with two positioning notches which are symmetrical about the central axis of the side wall.
Preferably, a heat insulation interlayer is further arranged in the side wall, and the heat insulation interlayer is a hollow cavity or a rock wool interlayer.
The utility model has the advantages that: a positioning notch matched with the workpiece bulge is additionally arranged at the bottom of the side wall of the riser, so that the riser can be tightly attached to the workpiece, the gap is reduced, and the riser can be prevented from shifting; the exhaust port is enlarged to 30-50% of the area of the top cover, the exhaust efficiency is increased, and the feeding effect is more obvious.

Detailed Description
The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the embodiments after studying the specification. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The utility model provides a K6 is kidney circle heat preservation rising head for bolster as shown in fig. 1-2, including lateral wall 1, the inner chamber that encloses by lateral wall 1 and set up the top cap 2 at lateral wall 1 top, 1 inner wall of lateral wall perpendicular to rising head bottom surface. The side wall 1 and the top cover 2 can be made into slurry by mixing heat-insulating materials (such as aluminum silicate fiber cotton, rock wool, mineral wool and the like), refractory materials (such as calcined alumina, quartz sand, quartz powder and the like) and bonding materials (such as starch, water glass and the like), a special mold is used for vacuum suction filtration molding, the slurry is integrally molded after airing, drying and curing, an opening is formed at one end of the side wall 1, which is far away from the top cover 2, namely the bottom surface of a riser, the end is connected with a tool, and after molding is completed, an inner cavity is communicated with a cavity of a sand mold through the opening. One end of the side wall 1, which is far away from the top cover 2, is provided with a crescent positioning notch 4. The positioning notch 4 is matched with the bulge on the tool, so that the riser can be tightly attached to the tool, the gap is reduced, and meanwhile, the positioning effect on the riser is achieved, the sand culture repairing operation is cancelled, the riser is prevented from shifting during modeling, and the production efficiency is increased.
The top cover 2 is provided with an air outlet 3, and the area of the air outlet 3 on the top cover 2 accounts for 30% -50%. The blind riser that uses among the prior art generally only sets up the exhaust hole that a diameter is about 10~20 mm, the utility model discloses expand the exhaust hole for the gas vent, and its area accounts for 30~50% of top cap area to increase exhaust efficiency, guarantee to pour a large amount of gases that the in-process produced and can in time discharge, make the feeding effect more obvious.
When the mould is used, a riser is placed on the tool and then is filled with sand for moulding, the mould is turned over and demoulded after the sand mould is hardened, and the riser is embedded in the upper casting mould after being demoulded along with the sand mould. When the mould is closed for pouring, the liquid level of the molten steel slowly rises until the molten steel overflows from the exhaust port at the top of the riser, the solidification volume of the casting is contracted, and the molten steel in the riser is finally solidified under the heat insulation effect of the riser to perform feeding on the casting below the riser.
Preferably, the projections of the side wall 1 and the exhaust port 3 on the roof 1 are both waisted and coaxial.
Preferably, the bottom of the side wall 1 is provided with two positioning notches 4 which are symmetrical about the central axis of the side wall 1.
Preferably, in another embodiment as shown in fig. 3, a thermal insulation interlayer 5 is further disposed in the side wall 1, and the thermal insulation interlayer 5 is a hollow cavity or a rock wool interlayer, so as to further reduce heat transfer efficiency and enhance the heat preservation effect of the riser.
The foregoing is directed to one or more embodiments of the present invention, which are described in some detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
