Description
Technical field
The present invention relates to mold production technical field, in particular to a kind of mold for applying special-shaped water route 3D printing produces work
Skill.
Background technique
Mold is widely used, and the product members forming in modern manufacturing industry almost requires to complete using mold.
So Die Industry is the important component of national new high-tech industry, it is important, valuable technical resource.
3D printing technique is a kind of advanced manufacturing technology occurred late 1980s, which is based on successively superposition material
Complicated STRUCTURE DECOMPOSITION is two dimension manufacture, can quickly produce arbitrarily complicated structure by the manufacturing theory of material.
It is had begun working on currently, directly manufacturing injection mold using laser 3D printing technology, but forming technology, forming effect
Rate and stability etc. are not able to satisfy production requirement still.The mould caused by biggish thermal stress gradient especially in laser forming process
Have the metallurgical imperfections such as steel cracking, low-melting alloy elements vaporization, seriously constrains 3D printing technique answering in injection mold field
With.
And during mold production, the cooling for mold is essential step.The prior art is for mold
Cooling mostly using in mould bases mode using the perforative holes of some machinings, no using certain medium (water or oil)
That stops transmits heat inside to achieve the purpose that control mold temperature, and for the product of some complex contours, conventional borehole
The water route of formula is cooling due to not can guarantee mold cavity surface uniform throughout, will lead to that product cooling is irregular, and qualification rate is low.
Summary of the invention
It uniformly cools down, accelerates cold present invention aims to solve the deficiencies of the prior art, and provides a kind of one kind can be realized mold
But speed shortens the mold production technology of the special-shaped water route 3D printing of application of mold cooling time.
The present invention solve the above problems used by technical solution be:A kind of mold production for applying special-shaped water route 3D printing
Technique, which is characterized in that include the following steps:
(1) Element Design:Part model is designed according to the actual situation, and passes through modelling abnormity water route;
(2) mold flow analysis:The analog simulation that computer completes injection molding is crossed, the concept feasible of mold is assessed;
(3) 3D printing:By metal powder by heat treatment, printout is carried out according to part model and special-shaped water route;
(4) mold assembly and injection molding.
In some embodiments, in step (3), using laser sintered processing technology, laser energy is used for the gold
Belong to powder fusing, using scanning means, is processed from level to level.
In some embodiments, the inlet opening in the special-shaped water route and apopore synchronize printing, institute in step (3)
It states and is printed with screw thread on inlet opening and apopore.It is connect when facilitating subsequent use with external source.
In some embodiments, in step (1), the abnormity water route is changed with the shape of the part model.
The exposure level of special-shaped water pipe and product surface can be utmostly improved, cooling efficiency is improved.
The advantage of the invention is that:Special-shaped water route and mold are integrally formed using 3D printing, set according to the shape of mold
The trend in special-shaped water route, more efficient adjusting mold surface temperature are set, so that mold temperature controls in the range of a setting,
It realizes that product uniformly cools down, accelerates cooling velocity, shorten mold cooling time, reduce plastic cement lacking due to the even generation of inhomogeneous cooling
It falls into.
Specific embodiment
Below with reference to embodiment, the present invention will be further described.
A kind of mold production technology for applying special-shaped water route 3D printing, which is characterized in that include the following steps:
(1) Element Design:Part model is designed according to the actual situation, and passes through modelling abnormity water route;
(2) mold flow analysis:The analog simulation that computer completes injection molding is crossed, the concept feasible of mold is assessed;
(3) 3D printing:By metal powder by heat treatment, printout is carried out according to part model and special-shaped water route;
(4) mold assembly and injection molding.
Specifically, wherein special-shaped water route refers to shape of product variation and changes arbitrary shape cooling-water duct, use
The advantages of special-shaped water route is sufficiently to can be realized product close to product surface and uniformly cool down, and accelerates cooling velocity, and it is cold to shorten mold
But the time reduces plastic cement due to the defect of the even generation of inhomogeneous cooling.
In step (3) 3D printing, using laser sintered processing technology, laser sintered is a layering processing and manufacturing skill
Art, the premise of this technology are that the three-dimensional data of object is available.Then three-dimensional description is converted into a whole set of slice, each cuts
Piece describes the part cross-section of determining height.Laser sintered machine is got up by accumulations that these are sliced in layer, from
And obtain required object.In each layer, laser energy be used to melt in powder.By means of scanning means, laser energy
It is "printed" on powder bed, this creates the terminal a cured layer, this layer subsequently becomes a part of completion object.It is next
Layer again continue to be processed on the first layer by face, until whole process is completed.By the way of 3D printing, solve for
Cooling water channel can only use traditional depth drill, edge, the techniques such as electric pulse, can be with based on water route is also formed into a loop with aplysia punctata
Frank and outspoken water route arrangement mode is avoided, most reasonable water route circuit is found in limited cavity wall thickness.
Preferably, the inlet opening in special-shaped water route and apopore synchronize printing, the inlet opening in step (3)
With screw thread is printed on apopore.It is connect when facilitating subsequent use with external source.
Special-shaped water route and mold are integrally formed using 3D printing, the trend in special-shaped water route is set according to the shape of mold,
More efficient adjusting mold surface temperature, so that mold temperature control in the range of a setting, realizes that product uniformly cools down,
Accelerate cooling velocity, shorten mold cooling time, reduces plastic cement due to the defect of the even generation of inhomogeneous cooling.
Only highly preferred embodiment of the present invention is described above, but is not to be construed as limiting the scope of the invention.This
Invention is not only limited to above embodiments, and specific structure is allowed to vary.All protection models in independent claims of the present invention
Interior made various change is enclosed to all fall in the scope of protection of the present invention.
