Pull, ensure finished product rate.
Therefore, the purpose of this utility model is to provide a kind of apparatus for pouring for high-pressure casting mould.
In one side of the present utility model, there is provided a kind of apparatus for pouring for high-pressure casting mould, including material cake
(1), cross gate (2), ingate (3), accumulated slag bag (4) and cross gate (6), it is characterised in that：Described ingate (3) and casting
(5) surface connects in joint form, and ingate (3) is arranged so that aluminium water through ingate (3) in importing die cavity in terms of tangent line；Institute
Cross gate (2) the V-shaped structure stated, including it is connected to the input of material cake (1) and be connected respectively with ingate (3) two
Output end；Cross gate (2) successively decreases step by step towards the cross-sectional area in ingate (3) direction, cross gate (6) circular arc mistake at nearly cast gate
Cross and be connected to ingate (3)；What described accumulated slag bag (4) was arranged in casting fills type end, Lv Shui intersections and the core back side.
At the preferable aspect of the utility model, described cross gate (2) V-shaped structure, bifurcation angle is in 40~70 ° of scopes
It is interior.
