Description
Technical field
The present invention relates to a kind of 3D print die and manufacture method thereof, particularly relate to a kind of 3D with hollow out design and print
Mould.
Background technology
In recent years, along with rapid shaping, it is commonly called as the fast-developing application in China of the 3D printing technique, especially in this technology
Metal dust Selective Laser Sintering or selective laser melting technology attempt in injection-moulded plastic part Making mold apply,
Shorten die manufacturing cycle greatly, make mould development design more reasonable.
Figure 1A and Figure 1B shows the mould 1 manufactured by 3D printing technique.The die ontology 2 of mould 1 substantially becomes cylinder
Shape.It will be seen that the middle part of die ontology 2 is provided with a die cavity 3 from the section shown in Figure 1B, cooling water channel 6 around
Die cavity 3 is arranged, thus plays cooling effect during the use of mould 1.Cooling water channel 6 is from the general planar of die ontology 2
Bottom surface extends near die cavity 3, and arranges around die cavity 3, finally extends to another position of the bottom surface of die ontology 2.Cold
But water route 6 forms water inlet port 61 and water outlet port 62 on bottom surface.
Traditional mould processing technology is processed by cutting down material, and 3D printing technique is adopted just the opposite
It is processed by the form increasing material.3D printing technique is particularly well-suited to possess complex-shaped surface mould profile and complicated cooling water channel
Mould.But, for current 3D printing technique development, be suitable to the metal dust material being used as to print in the 3D manufacturing mould
Material price is costly.Such as form the mould 1 shown in Figure 1A, 1B, by the production of the mould 1 that 3D printing technique is fabricated by
Cost is of a relatively high.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of 3D print die, 3D print die includes being beaten by 3D
Being printed as the die ontology of shape, die ontology has forming cavity, and wherein, die ontology also includes at least one separated with forming cavity
Hollow-out parts.
According to an aspect of the present invention, also including cooling water channel in die ontology, cooling water channel is near forming cavity extremely
Few a part of cavity surface the arrangements along at least some of cavity surface, at least one hollow-out parts is arranged in and cooling water channel
The position separated.
According to another aspect of the present invention, cooling water channel is arranged between hollow-out parts and forming cavity.
According to another aspect of the present invention, forming cavity is formed on the one side of die ontology, at least one hollow-out parts
Other sides outside the side forming forming surface are recessed.
According to another aspect of the present invention, die ontology is cylindrical shape, and hollow-out parts is around columnar die ontology
Circumference arrange scrobicular ring.
According to another aspect of the present invention, die ontology is hexahedron, and die ontology also includes side hollow-out parts or the end
Face hollow-out parts, wherein on recessed five faces surrounding into die cavity being arranged on die ontology of side hollow-out parts.
According to a further aspect of the invention, being provided with ribs in hollow-out parts, openwork part is divided into multiple little by ribs
Chamber.
Additionally, present invention also offers a kind of method forming 3D print die as above, wherein, printed by 3D
Integrally formed hollow-out parts and forming cavity.
In the above-mentioned methods, it is preferred that before 3D printing is carried out, design is with hollow-out parts and the mould of forming cavity；?
After the 3D of mould has printed, mould is cut from the base plate of 3D printing device and removes；And mould is carried out heat treatment
To go de-stress.
Use the 3D mould according to the present invention and manufacture the Method of printing of 3D mould, can be before ensureing mould strength
Put, save the printing raw material needed, save manufacturing expense, meanwhile, alleviate the weight of mould.
Additionally, due to the volume that need to print is obviously reduced, therefore, the manufacture according to the 3D print die method of the present invention is fast
Degree also will faster.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the invention will be further described.Elaborate more in the following description
Details so that fully understanding the present invention, but the present invention obviously can come real with multiple this alternate manner described that be different from
Executing, those skilled in the art can make similar popularization according to practical situations, drill in the case of intension of the present invention
Unravel silk, the most should be with content constraints protection scope of the present invention of this specific embodiment.
Fig. 2 A and Fig. 2 B show according to a first embodiment of the present invention, vertical by the mould 10 of 3D printing technique molding
Body figure and sectional view.This mould 10 uses 3D printing shaping technology molding, such as metal dust Selective Laser Sintering
(SLS) material or selective laser melting technology (SLM), being suitable for includes 1.2709 steel.
It will be seen that the mould 10 of 3D printing shaping has the die ontology 11 of general cylindrical shape from Fig. 2 A and Fig. 2 B,
It has top side, bottom side and the peripheral side extended between top side and bottom side.The forming cavity 13 that mould 10 has is from die ontology
The recessed formation in top side of 11.Cooling water channel 16 is also included, smooth from die ontology 11 of this cooling water channel 16 in die ontology 11
Bottom side at start to extend near forming cavity 13, and surround into the arrangements of die cavity 13, finally extend to die ontology 11
Another position of bottom side.Cooling water channel 16 forms water inlet port 161 and water outlet port on the bottom side of die ontology 11
162, two ports 161,162 are arranged on two diverse locations kept at a certain distance away.
According to this embodiment of the invention, die ontology 11 is provided with hollow-out parts 181,182, and hollow-out parts 181,182 is distinguished
It is arranged on two diverse locations.First hollow-out parts 181 is arranged on the side relative with forming cavity 13 of die ontology 11, i.e. the
One hollow-out parts 181 is from the recessed formation in the bottom side of die ontology 11, it is preferable that the first hollow-out parts 181 arranges substantial cylindrical.Second
Hollow-out parts 182 is arranged on the peripheral side of die ontology 11, i.e. be formed about the circumference setting of columnar die ontology 11
Scrobicular ring.First hollow-out parts 181 and the second hollow-out parts 182 are arranged at the position separated with cooling water channel, and, hollow-out parts
181, the distance (material wall thickness) between distance and hollow-out parts 181,182 and the forming cavity 13 between 182 and cooling water channel 16
It suffices that the requirement of strength that mould 10 is in use.
Second hollow-out parts 182 may not be the scrobicular ring of continuous extension one circle, but is divided into multistage recess
Section, such as three, four or six etc., separated by ribs between adjacent recessed section.Additionally, spaced hollow-out parts is relatively
It is symmetrical arranged goodly.Such structure, particularly with for the mould 10 that volume is bigger, can strengthen die ontology 11 further
Intensity.Moreover it is preferred that above-mentioned ribs is arranged on the position closest to cooling water channel 16.
Fig. 3 A and Fig. 3 B be respectively the most according to a third embodiment of the present invention, vertical by the mould 20 of 3D printing technique molding
Body figure and sectional view.
3D print die 20 according to the 3rd embodiment has the die ontology 21 of a general square shape, its have top side,
Bottom side and four the smooth sidepieces extended between top side and bottom side.The forming cavity 23 of mould 20 is from the top side of die ontology 21
Recessed formation.Also including cooling water channel 26 in die ontology 21, cooling water channel 26 extends to from a position of smooth bottom side
Forming cavity 23 close beneath, and along the arrangements bottom forming cavity 23 below forming cavity 23, finally extend to die ontology
Another position of the bottom side of 21.Cooling water channel 26 forms water inlet port 261 and water outlet port 262 on bottom surface.
