[ detailed description ] embodiments
The first embodiment is as follows:
the directional position descriptors such as "up", "front", "rear", "left" and "right" in the present embodiment are all in terms of the approximate direction in which molten iron enters the gating system during casting.
Referring to fig. 1 to 5, the high-strength green sand casting system 100 of the oversized traction sheave casing of the embodiment is a sand mold for casting the traction sheave casing 200, the traction sheave casing 200 has an upper plate surface 201, a front side plate surface 202, a left side plate surface 203, a right side plate surface 203, and a rear side plate surface 204, the traction sheave casing 200 extends downward from the upper plate surface 201 to form a thin-walled annular outer casing 205, a thin-walled annular inner casing 206, and a central shaft cylinder 207, which are coaxially distributed from outside to inside, and the bottoms of the front side plate surface 201 and the central shaft cylinder 207 protrude from the bottoms of the thin-walled annular outer casing 205 and the thin-walled annular inner casing 206.
For the design of the pouring system of the traction sheave casing 200 described in this embodiment, the greatest difficulty is that there are multiple thin-walled ring shell structures in the casting, such as the thin-walled ring outer shell 205, the thin-walled ring inner shell 206, the central shaft cylinder 207, and the front side plate face 202, which all have large height drops, the respective water inlet height drops of the central shaft cylinder 207 and the front side plate face 202 reach 430mm, and the water inlet height drops of the thin-walled ring outer shell 205 and the thin-walled ring inner shell 206 also have 330mm, which is very large in impact on a sand mold, and is very likely to cause sand voids in the sand mold. In addition, the size of the traction sheave casing 200 in this embodiment is very large, the distance from the front side plate surface 202 to the rear side plate surface 204 is as long as 760mm, and the rear side plate surface 204 is further extended outward to form a plurality of connecting ear plate portions 208, so that the distance between the front and rear of the casting is 860mm, and the mold filling distance is too long, which may cause the sand mold to be subjected to the firing of high-temperature molten iron for a long time, and the sand collapse phenomenon is easy to occur, and the risk is great.
Therefore, in order to solve the above-mentioned technical problems, the high-strength green sand casting system 100 of the large-sized traction sheave casing of the present embodiment includes a molding cavity that is formed to be similar to the traction sheave casing 200, a pair of hot risers 2 and a plurality of ingate water inlet pieces 3 that inject molten iron into the molding cavity, a plurality of heat-generating risers 4 provided at hot junctions, and a plurality of auxiliary ingate water inlet pieces 5 that shorten a mold filling path.

In this embodiment, the first group of auxiliary water inlet sheets and the second group of auxiliary water inlet sheets are all provided with four sheets, and are uniformly distributed in a ring shape, so that the thin-wall circular ring outer shell 205, the thin-wall circular ring inner shell 206 and the central shaft cylinder 207 can be simultaneously filled with molten iron, if no auxiliary inner gate water inlet sheet 5 is provided, the molten iron firstly enters the thin-wall circular ring outer shell 205 from the bottom through the inner gate water inlet sheet 3, then falls downwards into the thin-wall circular ring inner shell 206 through the upper plate surface part 201, and then falls downwards into the central shaft cylinder 207 through the upper plate surface part 201 to be filled with molten iron, the filling path is long, the time is long, the efficiency is low, the sand mold is large in examination, and the sand mold is difficult to bear the long-time high-temperature molten iron firing; however, the thin-wall circular ring outer shell 205, the thin-wall circular ring inner shell 206 and the central shaft cylinder 207 are communicated through the arrangement of the auxiliary inner sprue water inlet sheet 5, so that the pouring path is greatly shortened, the pouring time is shortened, and the pouring efficiency is improved; and the auxiliary inner gate water inlet sheet 5 is arranged at the position close to the bottom of the thin-wall circular ring outer shell 205 and the thin-wall circular ring inner shell 206, so that the height difference of the molten iron filling type of the central shaft cylinder 207 part is shortened by nearly half, and the impact force on a sand mold during the molten iron filling type is greatly reduced.
