Propose a kind of running gate system of high-pressure casting mould.
The invention discloses a kind of running gate system of high-pressure casting product, including material cake (1), cross gate (2), ingate
(3), accumulated slag bag (4).A kind of pouring gate structure of aluminum alloy die-casting die of the invention, ingate design attitude substantially avoid aluminium
Liquid washes away to the big core of mould, it is ensured that aluminium liquid reduces the defect of pulling of product in the stationarity of die cavity internal flow, produces
Quality is all ensured well.
The invention provides a kind of running gate system of high-pressure casting mould, the described mould for aluminium alloy high pressure casting
Running gate system includes material cake (1), cross gate (2), ingate (3), accumulated slag bag (4), it is characterised in that：Described ingate (3)
It is connected in joint form with casting (5) surface, aluminium water imports die cavity through ingate (3) in tangent line aspect；Described cross gate (2)
V-shaped structure, including it is connected to the output end of the input for expecting cake (1) and two for being connected with ingate (3) respectively, angle of forking
Degree is in the range of 40~70 °；Cross gate (2) successively decreases step by step towards the cross-sectional area in ingate (3) direction, and horizontal at nearly cast gate is poured
Road (6) arc transition is connected to ingate (3), depending on charging angle is with the product-forming at nearly cast gate, is approximately parallel to closely pour
Cast(ing) surface at mouthful；What described accumulated slag bag (4) was arranged in casting fills type end, Lv Shui intersections and the core back side.The present invention
For the die casting system of aluminium alloy high pressure casting, advantage is：In cavity filling process, aluminium water into filling moldeed depth after die cavity first
The position being vented is difficult at chamber, then flows to die joint, the content of cast-internal stomata can be reduced, mitigate pulling for casting, protected
Card finished product rate.
It is therefore an object of the present invention to provide a kind of apparatus for pouring for high-pressure casting mould.
In one aspect of the invention, 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 imports die cavity through ingate (3) in tangent line aspect；It is described
Cross gate (2) V-shaped structure, including be connected to material cake (1) input and be connected with ingate (3) respectively two it is defeated
Go out end；Cross gate (2) successively decreases step by step towards the cross-sectional area in ingate (3) direction, cross gate (6) arc transition at nearly cast gate
It is 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.
In currently preferred aspect, described cross gate (2) V-shaped structure, bifurcation angle is in the range of 40~70 °.
Cross gate (6) at currently preferred aspect, described nearly cast gate is connected to interior pouring with arc form transition
Mouth (3), depending on charging angle is with the product-forming at nearly cast gate, is approximately parallel to cast(ing) surface at nearly cast gate.
Currently preferred aspect, what described accumulated slag bag (4) was arranged in casting fills type end, Lv Shui intersections and core
The back side.
Device advantage of the invention is：In cavity filling process, aluminium water is difficult to be vented into filling first after die cavity at moldeed depth chamber
