Abstract
A kind of 3D prints the mould of processing, including core, die cavity, water channel, it is characterised in that: it is arranged around blind hole at described core, die cavity, water channel, described blind hole embeds metalwork, makes described core or die cavity and metal parts be integrally formed.Owing to being arranged around blind hole at core, die cavity, water channel, therefore decrease the use of printed material, reduce the cost of raw material.Can be greatly improved the mold injection pressure that 3D prints, the performance of the batch production part of mould is suitable with the mould of machining, meets plastic compression production requirement simultaneously.
Description
Technical field
The present invention relates to mold machining technology, 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 core, die cavity, water channel, it is characterised in that: it is arranged around blind hole at described core, die cavity, water channel, described blind hole embeds metal parts, makes described core or die cavity and metal parts be integrally formed.
Preferably, described blind hole is circular or polygon.The diameter of blind hole or long-diagonal
For 5-30mm.
Preferably, described blind via bottom is taper or step taper.
Preferably, described step taper comprises step, and described numbers of steps is 1-3, and the width of described step is S≤5mm, 30 ° ~ 60 ° of described diminished shaft cross section base angle.
Preferably, diameter or the long-diagonal of blind hole is 8-20mm.
Preferably, blind hole is provided with drafting angle, and drafting angle is 0 °-3 °, particularly preferably
, blind hole is provided with drafting angle, and drafting angle is 0.5 °-2 °.
Preferably, described metalwork size is relative to blind hole inside dimension existence ± 0.03mm-1mm
Error.
Preferably, the material of described metalwork is mould steel.
Preferably, the material of described metalwork is P20, NAK80, beryllium copper.
Preferably, described mould water channel is more than or equal to 4mm away from mould distance core, the distance of die cavity.
The present invention compared with the prior art, has the following advantages and beneficial effect:
(1) owing to being arranged around blind hole at core, die cavity, water channel, therefore decrease and beat
The use of printed material material, reduce the cost of raw material.
(2) owing to being arranged around blind hole at core, die cavity, water channel, therefore can shorten
Time-write interval, improve production efficiency, reduce time cost.
(3) mould processing due to current 3D printing material bears the pressure of injection and tradition steel matter mould exists gap, therefore blind hole is reserved in a mold, add metalwork in blind hole position simultaneously, core or die cavity is made to be integrally formed with metal combination part, by adding metalwork, can be greatly improved the mold injection pressure that 3D prints, 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.
