Specific embodiment
For the technical characterstic for illustrating this programme can be understood, below by specific embodiment, and its accompanying drawing is combined, to we
Case is illustrated.
A kind of high manganese steel frog production cast sandbox, as illustrated, it includes being provided with rut in casing 8, the casing 8
Forked type chamber 6 and with the parallel arrangement of upright casting road 4 of railway frog die cavity 6, the top in upright casting road 4 is provided with sprue cup 1.The upright casting road
Multiple ingates 5 communicated with both are provided between 4 and railway frog die cavity 6.Wherein, the self-support running channel 4 of ingate 5 is to railway frog die cavity
6 incline from bottom to top, have equal angle α between the center line and the center line in upright casting road 4 of each ingate 5, angle α
Span is 70 °≤α≤80 °, and preferably the value of angle α is α=75 °.
The top of the casing 8 is provided with the exothermic riser 3 communicated with railway frog die cavity 6, the exothermic riser 3 and is provided with
Exothermic shield 2, exothermic riser 3 includes that straight tube exothermic riser and position of the position under, can be with upper necking down exothermic riser
