Embodiment 1:
As shown in connection with fig. 1, the present embodiment provides a kind of impeller fusible pattern and shell of impeller for casting impeller, impeller fusible patterns
Including wheel hub wall 1, wheel cap 2, blade wall 3 and exhaust outlet 4, the wheel hub wall 1 of impeller fusible pattern is hollow structure, and impeller fusible pattern uses 3D
The mode of printing rapid shaping makes, and the blade wall 3 of impeller fusible pattern is hollow structure, and the size of impeller fusible pattern is impeller size
1.01 times to 1.02 times, the exhaust outlet 4 of impeller fusible pattern is provided with the supporting element 5 for being used to support impeller fusible pattern exhaust outlet 4, supporting element
5 be the support ring that 4 inner wall of exhaust outlet is arranged in, and the width of support ring is 1mm to 2mm, a kind of shell of impeller, using above-mentioned impeller
Model casting shell of impeller, the wheel hub wall 1 of impeller fusible pattern are hollow structure, in shell of impeller manufacturing process, avoid impeller fusible pattern
Shell is split up in gasification.
Embodiment 2:
Refering to what is shown in Fig. 1, the present embodiment provides a kind of Impeller Shaping technique and impellers, comprising the following steps:
By the rapid prototyping system of the threedimensional model input 3D printer of impeller fusible pattern, impeller fusible pattern moulded dimension is than needing
The impeller size of preparation is 1.01 times -1.02 times big, 3D printing go out impeller fusible pattern than 1.01 times -1.02 times of impeller size, to
There is certain contraction than column, impeller fusible pattern compares impeller after pouring metallic solution in shell of impeller, after metallic solution process of setting
1.01 times -1.02 times of size, the precision of impeller is effectively ensured；
Using heat-shrinkable materials as printed material, printed material is powdered PSB material, is sieved and is fought each other using three-dimensional vibrating
It prints material and carries out screening and filtering, remove impurity and larger particles in printed material, PSB material is wax-based material, heating temperature
Without carrying out filling protective gas to operating room when gasifying when reaching 500 DEG C and residue be less, and being sintered using PSB material laser
Protection.
