Abstract

The invention discloses a forming and shunting mold for a hollow guide rail for a mine. The mold comprises an upper mold and a lower mold capable of being fixedly connected with the upper mold, wherein a shunting hole is formed in the upper mold and comprises a first shunting part and a second shunting part, the first shunting part directly faces middle parts of vertical ribs and a hollow position of a bottom edge wall, the second shunting part directly faces ends of the vertical ribs, and a metal flow-guiding groove expanding outwards in a direction close to the middle parts of the vertical ribs and the hollow position of the bottom edge wall is formed in the first shunting part. In the forming and shunting mold for the hollow guide rail, the metal flow-guiding groove expanding outwards in a direction away from the shunting hole is formed in the first shunting part, the flow area of a whole metal flow-guiding cavity in the position of the first shunting part is enlarged, metal flow velocities in positions of the middle parts of the vertical ribs and the hollow position of the bottom edge wall are decreased, the metal flow velocity difference during extrusion is further decreased, and the forming quality of the hollow guide rail is improved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a hollow guide rail forming diverter mold for mines. Background technique [0002] The hollow guide rail for mines is U-shaped as a whole, and the four corners are triangular guide rails. The hollow guide rail includes two vertical ribs and a bottom side wall connected to the two vertical ribs at both ends, wherein a hollow part is arranged in the middle of the bottom side wall. Among them, the hollow guide rail forming splitter mold is used for the extrusion molding of the hollow guide rail. [0003] The traditional hollow diversion forming diverter mold includes an upper die and a lower die. The upper die is provided with a diverter hole, wherein the diverter hole is a channel for the metal to lead to the mold hole. However, since the final thickness of both ends of the vertical rib of the hollow guide rail profile is 52.6mm, while the wall thickness of the middle part of the ...
