Abstract
The utility model relates to a super-long thin rib step-type aluminum alloy die casting mould for an LED support frame, which comprises a support frame (1), a slope-type equi-height step-type mould (2), a cup-type casting system (3), a feeding system (4), a cold material exhaust system (5) and an ejection system (6), wherein a cavity is arranged in the middle position of the slope-type equi-height step-type mould (2); the support frame (1) is arranged on the cavity; the feeding system (4) is arranged on one side of the support frame (1); and the cold material exhaust system (5) is arranged on the other side of the support frame (1). The die casting mould has the advantages that quality can be guaranteed; and the production efficiency is improved.
Description
Technical field
The utility model belongs to the die casting technical field, particularly relates to the thin rib ladder type of a kind of overlength LED bracing frame aluminum alloy die-casting die.
Background technology
A kind of left-right symmetry type LED car light bracing frame, vector, high low head and projected area have reached 15: 1: 5 improper ratio specifications in length and breadth for they, whole product is irregular cambered surface ladder type stepped profile, and thin rib thinnest part size only has 1.15mm, and the whole high low head of product surpasses 290mm.Irregular being distributed on the stent substrate of fixed leg, installing hole, lightening core of 35 different size sizes of while product.So that this product has and strict requirement mould structure, manufacturing process, process technology.
For these problems, company has carried out many-sided process improving and technological innovation to mould structure, technological parameter, mold materials, condition of molding.In Design of Dies, carry out in advance the mold flow analysis of specialty according to product structure characteristic, the CAE software of application of advanced is selected the best somatotype scheme of mould, with the symmetrical mirrored arrangement of die cavity, homogenize casting and the complete reasonable integration of charging, exhaust, cold burden and ejection system.Use the AnyCasting compression mod flow analysis simulation software of 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 in advance later stage actual moulding.
The utility model content
Technical problem to be solved in the utility model provides the thin rib ladder type of a kind of overlength LED bracing frame aluminum alloy die-casting die, can ensure the quality of products, and enhances productivity.
The technical scheme that its technical problem that solves the utility model adopts is: the thin rib ladder type of a kind of overlength LED bracing frame aluminum alloy die-casting die is provided, comprise bracing frame, the contour notch cuttype mould of slope formula, cup type casting system, feed system, the cold burden gas extraction system, ejection system, the contour notch cuttype mould of described sloping formula centre position is die cavity, is bracing frame on the die cavity, bracing frame one side is feed system, and the bracing frame opposite side is the cold burden gas extraction system.
Described feed system is communicated with cup type casting system.
The contour notch cuttype mould of described sloping formula has the guide pillar hole on four angles.
Beneficial effect
The utility model has adopted the efficient mould structure technology of more conventional difference, and mould structure is simplified, and integrates mould bases, framed, increases mould strength and has guaranteed again global consistency, reduces and repeats 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, the life of general 6.5 ten thousand moulds time to surpassing 80,000 moulds, and is avoided moulding mould strain and the tired attitude of moulding midway.This many places multi-spot balancing feed system, having nearly, 15 bores are that 6mm * 2.5mm * 2mm becomes trumpet-shaped charging aperture, and charging aperture is equally spaced to whole product periphery and plane, only need that 6 seconds high-speed synchronous are filled, 2 seconds fast shapings, rapidly cooling in 2 seconds, greatly reduced the HTHP liquid state and washed away damage to mould.Can realize finishing in 10 seconds 27 seconds moulding of conventional mould structure action, efficient has nearly 3 times lifting.In the actual product test, adopt the intact material of product surface of Novel die structure, without peeling and cold shut, internal particle is evenly distributed, free from admixture, bubble, pore, stop many defectives such as original product filling is full not, insufficient strength, realized rising to of matter.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Such as Fig. 1 ~ shown in Figure 2, the thin rib ladder type of a kind of overlength LED bracing frame aluminum alloy die-casting die comprises bracing frame 1, the contour notch cuttype mould 2 of sloping formula, cup type casting system 3, feed system 4, cold burden gas extraction system 5, ejection system 6, the contour notch cuttype mould of described sloping formula 2 centre positions are die cavity, be bracing frame 1 on the die cavity, bracing frame 1 one sides are feed system 4, and bracing frame 1 opposite side is cold burden gas extraction system 5.
Described feed system 4 is communicated with cup type casting system 3.
The contour notch cuttype mould of described sloping formula has the guide pillar hole on 2 four angles.
Liquid HTHP metal enters 11 place's feed systems 4 after being shunted by cup type casting system 3 guiding simultaneously, then the contour ladder die die cavity 2 of simultaneously high speed filling slope formula, in stowing operation, discharge cold burden and gases by cold burden gas extraction system 5, liquid HTHP metal after being cooled to fine and close product under the contour ladder die die cavity of the sloping formula high pressure by ejection system 6 ejecting products.
