Description
Technical field
The present invention relates to technical field prepared by mould, be specifically related to a kind of oblique top preparation method of special-shaped water route, and implement the oblique top of this preparation method.
Background technology
In injection moulding process, cooling procedure plays very important effect for Forming Quality, because it directly can have influence on the production efficiency of injection moulding and the internal performance of injection-molded item and apparent mass.Excellent cooling system significantly can reduce cool time, shortens the injection cycle cycle, reduces goods residual thermal stress and buckling deformation, and strengthens mechanical property and inside, the surface quality etc. of goods.If injection-molded item inhomogeneous cooling is even, can thermal residual strain be produced, thus the shape of injection-molded item, size and serviceability etc. are brought and had a strong impact on.Research test shows, a thermal residual strain order of magnitude at least larger than flowing residual stress of moulding, therefore in injection molding process, mainly should consider the influence factor of thermal residual strain.When viscoelastic polymer melt is cooled to lower than glass transition temperature in mould, uneven variable density and uneven variations in temperature all can form thermal residual strain.In injection moulding process, thermal residual strain easily produces in following 2 stages: one is the cooling stage of injection-molded item in die cavity, and two is injection-molded item stages from calcining temperature cool to room temperature.Therefore, high efficiency production be accomplished, and the injection-molded item of excellent, temperature adjustment must be carried out to mould.
In injection mold, the cooling effect of mould is related to the height of production efficiency and the quality good or not of final injection-molded item, and therefore the design of its cooling system is one of key issue needing in die design process to consider.But, because present stage Making mold means are limited, and lack suitable cooling water channel design theory, under making the Design and manufacture of cooling water channel can only be confined to relatively simple version.However, mold designers are still devoted to improve the cooling effectiveness of cooling system all the time, propose the water route form that spiral, dividing plate point cold type and spiral plug etc. are different, obtain evenly and effectively cooling to enable front and back mould.But, to those complex structures and the high product of quality requirement carries out Design of Dies time, said method is not fully effective.
Summary of the invention
This invention is not enough for current art, a kind of oblique top preparation method of special-shaped water route is provided, by the water route design repeatedly optimized, manufacture temperature by 3D printing technique and regulate excellent special-shaped water route and oblique top, improve the cooling effectiveness of mould or oblique top, shorten molding cycle, improve mould production efficiency, reduce moulding thermal residual strain, improve injection moulding quality.
The present invention also provides a kind of oblique top implementing this preparation method.
The technical scheme that the present invention is adopted for achieving the above object is:
The oblique top preparation method in special-shaped water route, it comprises and is provided with CAD 3D modeling software, CAE assistant analysis software, hierarchy slicing software, the computer of 3D print software and 3D printer, and it is characterized in that, it comprises the following steps:
(1) the three-dimensional modeling model of injection mould and oblique top is set up by CAE assistant analysis software, select rational injection molding parameter, simulation injection moulding production process, and compensate injection moulding by the profound and negative feedbck of CAE assistant analysis software and produce the change of product and the special-shaped waterway structure revised in advance in oblique top, make the cooling effect that the realistic injection moulding of oblique top is produced, thus obtain the three-dimensional archives of oblique top and special-shaped waterway structure, ensure that product reaches requirement;
(2) in CAD 3D modeling software, the oblique top that step (1) obtains is arranged bi-material, be respectively special-shaped waterway structure inwall in oblique top and the copper product of the thick high heat conduction of 0.3 ~ 0.6mm is set, abnormity waterway structure is equivalent to be arranged to a wall thickness be the heat-conducting copper pipe of 0.3 ~ 0.6mm, other positions that oblique top removes special-shaped waterway structure are die steel material, and export the three-dimensional archives of oblique top and special-shaped waterway structure;
(3) the three-dimensional archives hierarchy slicing software of oblique top step (2) obtained and special-shaped waterway structure processes it, obtain the information parameter of each cross sectional shape, the track of two-dimensional scan is carried out as laser beam, the light beam sent by laser is under the control of computer 3D print software, coordinate data according to each layer cross section of geometrical body scans different materials powder bed selectively, together powder sintered on the position of laser irradiation, after one deck has sintered, repave powder and carry out lower one deck scanning sintering, new one deck and front one deck are sintered together naturally, the oblique top that final generation follows three-dimensional archives consistent and special-shaped water route,
(4) the thick high heat conduction hard Graphene coating of 0.05 ~ 0.1mm is set at the position that ejects contacted with injection moulding plastic part of oblique top.
As further improvement, in described step (1), the running of the profound and negative feedbck of described CAE assistant analysis software specifically comprises the following steps:
(11) the three-dimensional modeling model of the injection mould set up and oblique top is imported to CAE assistant analysis software, selection material and injection molding parameter in CAE assistant analysis software, set up initial waterway structure;
(12) simulate injection moulding to produce, produce the product 3D model of simulation, and the distortion of the product 3D model of prognosis modelling,
Compared with original product model by the product 3D model of simulation, the difference of distortion is fed back to CAE assistant analysis software, CAE assistant analysis software regenerates the waterway structure of oblique top according to the difference of distortion, the three-dimensional modeling model of the oblique top be improved;
(13) again simulate injection moulding to produce, again obtain product model, and the distortion of the product 3D model of prognosis modelling, computer repeats above step (12) repeatedly automatically, until simulate the deformation requirements that the product generating out meets setting, the three-dimensional modeling model of the oblique top obtained is for Design of Dies and processing.Thus ensureing that the product that injection moulding is produced once meets product requirement, computer simulation replaces original by CAE assistant analysis technology Chief, passes through die trial, repair a die, advantage economizes on resources, and cuts the waste, the Speeding up development cycle, thus reach high-quality, efficient production requirement.
