Description
Technical field
The present invention relates to the 3D printing technique field of casting die, more particularly to a kind of FDM prints the side of die cavity class mould
Method.
Background technology
FDM is exactly fused glass pellet, is that one kind is squeezed heat-fusible materials in half flow regime using 3D printing equipment
Press out, material false set is formed with the printing technology of the thin layer of contour shape.The product printed using FDM forming techniques
Product, good with surface quality after processing, dimensional accuracy is high, long service life, the advantages of fabrication cycle is short.Therefore, as 3D beats
The continuous improvement of print technology, FDM forming techniques are applied in casting industry more and more widely.
The manufacturing process of FDM forming techniques is one and successively smears cumulative process, in printing similar to the die cavity shown in Fig. 1
During mould, traditional Method of printing is needed in mold cavity house print support frame, could complete the printing of top structure.Tool
When body is printed, first since bottom, successively print die outline, and after often printing completes one layer of mould outline, therewith by
Layer printing support frame.Printing until completing mould outline and support frame, just proceeds by the printing of top level structure.This
Sample one, not only constrains the printing effect of equipment, simultaneously as the printing of support frame, considerably increases printed material
Use, cause mould production cost high.
The content of the invention
The present invention needs specially to print what support frame was caused in printing die cavity class die method for FDM in the prior art
The problem that printed material is wasted, there is provided a kind of method that FDM prints die cavity class mould, to improve printing effect, reduces printing material
Material cost.
The object of the present invention is achieved like this, a kind of method that FDM prints die cavity class mould, comprises the following steps：

Filling thickness is the support particle of D, until completing the printing of mold height direction outline wall and the filling of inner chamber support particle.
Cavity wall print procedure of the invention, FDM prints one layer of outline, then is filled with height by jolt-packing device
Support particle, printing and jolt-packing alternately and repeatedly carry out, to complete the print procedure of cavity wall, the support particle of filling is
The printing of die top provides support.While this process reduces FDM printing costs, printing effect is improved.
Used as preferred scheme of the invention, the support particle is sand, glass bead, metal powder or the modeling of uniform particle sizes
Material particle, the particle diameter of the support particle is 1-5mm.
Further, the thermoplastic is ABS, PLA, HIPS, PC or nylon.
For ease of realizing jolt-packing process, it is described step by step b) in filler device include storage device, the storing
Device is connected by pillow mechanism with fuselage, and the storage device bottom is provided with discharging opening, the storing dress of the discharging opening side
Put wall and be provided with stragith edge, storage device outer wall is also associated with shaking device, when being supported particles filled, storage device goes out
The surface that material mouth is located at mould to be printed is moved back and forth by pillow mechanism driving directly over mould, and in jolt-packing
Support particle is struck off by stragith edge.Storage device of the invention, when dosing support particle, storage device can realize that side is filled out
The bed of material that material side will be dosed strikes off, easy to operate, efficiency high.
