Description
Technical field
The invention belongs to the compression mod technical field, particularly relate to a kind of Multifunctional LED heat radiation bracing frame aluminum alloy die-casting die.
Background technology
A kind of LED of collection installation, light modulation, the product that dispels the heat; Because its complex structure, curve form are irregular; The heat radiation thin slice is various, and vector, high low head and projected area ratio have reached 11: 5: 13 in length and breadth, and the whole high low head of product also surpasses 198mm.The product side is being uniformly distributed with the deep hole that a plurality of diameters are 3.5 dark 20mm, thereby this product has high requirement to mould structure, manufacturing process, process technology.
To this product, mould structure, technological parameter, mold materials, condition of molding many-sided process improving and technological innovation have been carried out.In the mould design, carry out professional mold flow analysis in advance according to product structure characteristic, the CAE software of application of advanced is selected the best somatotype scheme of mould, with die cavity symmetry mirrored arrangement, homogenize casting and charging, exhaust, cold burden and ejection system reasonable integration.The AnyCasting compression mod flow analysis simulation software of utilization specialty, process conditions and situation can realize preview and fine setting, the common process scheme that stop repetition test, repeats to revise when having showed later stage actual moulding in advance.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Multifunctional LED heat radiation bracing frame aluminum alloy die-casting die, can guarantee product quality, enhances productivity.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Multifunctional LED heat radiation bracing frame aluminum alloy die-casting die is provided, comprises dynamic model, positioning guide column, core-pulling mechanism synchronously; Independent cup type feeding mechanism, cold burden slagging device, cover half, step portion profile; Detent mechanism, submarine exhaust, feeding mechanism, Angle Pin mechanism; The location guide pin bushing, described cover half is installed on the dynamic model, and the dynamic model center is a upper impression; Upper impression all has the cold burden slagging device on four angles, and independent cup type feeding mechanism is arranged on upper impression one side, and the cover half center is a lower impressions; Lower impressions is forward and backward to have detent mechanism and feeding mechanism respectively, and lower impressions is left and right all to be the step portion profile, is the submarine exhaust on one jiao of the lower impressions.
Described cover half cooperates and is installed on the dynamic model with the location guide pin bushing through positioning guide column.
Described mould is through Angle Pin mechanism location dynamic model.
Beneficial effect
The present invention has adopted conventional the different technology of mould structure efficiently, and mould structure is simplified, and integrates mould bases, framed, increases mould strength and has guaranteed integral uniform property again, reduces the repetition rigging error.And mold cavity adopts detachable embedded mechanism, convenient processing, maintaining.In digital control processing, can avoid producing stress deformation and the dimension overproof phenomenon occurs, separately die is carried out vacuum heat treatment process, life-span of general 80,000 moulds time is extended to surpass 100,000 moulds, and avoid moulding mould strain and the tired attitude of moulding midway.The balanced feed system of this many places multiple spot; Nearly 12 bores are 5mm * 1.5mm * 2mm charging aperture; Become horn-like; Be equally spaced to entire product periphery and plane, only need high-speed synchronous filling in 15 seconds, 5 seconds fast shapings, cooling rapidly in 3 seconds, significantly reduced the HTHP liquid state and washed away damage mould.Can realize accomplishing 35 seconds moulding of conventional mould structure action in 20 seconds, efficient has nearly 1 times lifting.In the actual product test; Adopt the intact material in novel die constructed products surface, no peeling and cold shut, internal particle is evenly distributed, free from admixture, bubble, pore; Stop many defectives such as original product filling is full inadequately, insufficient strength, realized rising to of matter.
