Description
Technical field
The present invention relates to 3D printing technique, particularly belong to 3D printing technique and apply at processing mold
Field.
Background technology
Current 3D printing technique development is very fast, particularly 3D technology is applied in terms of the mould of processing, but current 3D technology is applied exists some problems at processing mold, the too big pressure of injection mold and impulsive force can not be born as 3D prints material compared with traditional moulds steel matter, performance and the mould of machining of the batch production part of mould can not compared with, therefore limit application in processing mold for the 3D printing technique.
Content of the invention
The problem existing for prior art, the invention provides a kind of 3D and prints the mould of processing, can steel matter mould is the same can be met plastic compression production requirement by injection pressure, save material with tradition, shorten the time-write interval, reduce cost.
The purpose of the present invention is achieved through the following technical solutions:
A kind of 3D prints the mould of processing, including appearance, non-part forming surface, forming parts face, core, die cavity, it is characterized in that: inside described die cavity, include grid engraved structure, sealing hole, inserting higher boiling, not volatile liquid in described grid engraved structure, the described hole that seals is arranged in the mould non-part forming surface with grid engraved structure, described sealing hole is configured with sealing device, by higher boiling, not volatile hydraulic seal in grid engraved structure.
Preferably, described grid engraved structure is polygon.
Preferably, described grid engraved structure is triangle, square, rectangle, water chestnut
Shape.
Preferably, described mould also has water route, ejects rod aperture position, described grid hollow out limit
Edge away from mould appearance face, water route, eject rod aperture position be more than or equal to 5mm.
Preferably, described grid engraved structure is made up of grid ribs, and described grid ribs is parallel
Space between the mould base plane that 3D prints processing is less than or equal to 6mm.
Preferably, the cross-sectional area of described grid ribs is more than or equal to 9mm2, grid ribs cross section is circular or regular polygon.
Preferably, having mould appearance face and the grid engraved structure edge sealing hole to arrange tapering, described tapering is between ~ 10:1.
Preferably, a diameter of 5-20mm in described sealing hole.
Preferably, higher boiling, the not volatile liquid inserted in described network engraved structure are organic silicone oil, ethylene glycol, hydraulic oil.
Preferably, the quantity in described sealing hole is more than or equal to 2, and the sealing hole that at least one of which is perfusion liquid is simultaneously provided with pressure sensor, for monitoring the pressure of mould inside liquid；At least a sealing hole is arranged on mold bottom, and uses check-valves to seal.
The present invention compared with the prior art, has the following advantages and beneficial effect:
(1) owing to arranging network inside mold cavity, configure respective numbers simultaneously
Sealing hole, sealing configuration sealing device on hole, with can be by hydraulic seal in network, owing to by arranging appropriate number of sealing hole position at mould inside, the use of printed material therefore can be subtracted in a large number, reduces the cost of raw material；Also bring the shortening time-write interval simultaneously, improve production efficiency, reduce the beneficial effect of time cost.
(2) mould processing due to current 3D printing material bears the pressure of injection and tradition steel matter mould exists gap, therefore grid engraved structure is reserved in a mold, seal corresponding liquid in grid engraved structure simultaneously, core or die cavity is made to be integrally formed with liquid-mixing component, the mold injection pressure that 3D prints can be greatly improved, the performance of the batch production part of mould is suitable with the mould of machining, meets plastic compression production requirement.In producing plastic compression, inlaid piece of mould bears the force analysis that carries out of pressure simultaneously, and the step that blind via bottom is arranged bears front injection pressure, and other direction injection pressures are born in taper surface and remaining cooperation face.
(3) there are the face sealing hole and grid engraved structure edge that tapering is set at mould, the support metal dust in grid engraved structure can be poured out when mould is processed smoothly, the quality of mould product has been effectively ensured.
