Description

A kind of apparatus for pouring for high-pressure casting mould
Technical field
The present invention relates to aluminium alloy high pressure casting field, and in particular to a kind of apparatus for pouring for high-pressure casting mould.
Background technology
Mould is modern industry, particularly the essential technique of the industry such as automobile, radio, aviation, instrument, commodity Equipment.The running gate system of high-pressure casting mould is the split channel that aluminium liquid flows to die cavity from injection chamber.Die casting system it is good It is bad, there is very important influence to the quality and productivity effect of die casting.
Pouring gate structure is needed according to the architectural characteristic of product come comp comprehensive layout, it is necessary to ensure that flowing of the aluminium liquid in die cavity is put down It is pliable, it is to avoid the gas hole defect of interiors of products, while needing reduction aluminium water to wash away mold cores, mitigate pulling for product scarce Fall into and improve die life, therefore rational running gate system is of crucial importance for aluminium alloy compression casting, can reduce live work Skill debugging difficulty, also can guarantee that product quality, improves the qualification rate of die-cast product, increase the performance of enterprises.
At present, the running channel and exhaust structure of mould factory's design arrangement often ignore high speed cavity filling process high temperature aluminium water pair Washing away for mold cores, pulls when can usually cause product depanning, even results in the fracture of core, while aluminium water slug is to core Shi Liuxiang will change, and aluminium water collides in die casting cavity filling process, wrap up in gas phenomenon, it is easy in casting Residual gas, produces gas hole defect, and the reduction of product compactness, product strength decline, percent defective can be caused to increase.
The content of the invention
Internal flaw in order to eliminate product of the invention, improves yield rate, saves production cost, increases economic efficiency, special 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 Position, then flow to die joint, the content of cast-internal stomata can be reduced, mitigate pulling for casting, it is ensured that finished product rate.
