It can not use.The back-up sand mouthful source of some core boxes needs to make fillet, with the method for stragith edge it is impossible to ensure that core is filled out
The quality in Sha Kou faces, needs design is a kind of can either ensure complicated back-up sand face and can retain back-up sand mouthful in this case
The method of fillet.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of method for the fillet for retaining irregular back-up sand face, the invention
The quality and shape of core are ensure that, complicated core production difficult problem is solved, and simplifies manual operations, work is improved
Efficiency.
A kind of method for the fillet for retaining irregular back-up sand face：
Comprise the following steps：
A. an aluminum that can retain back-up sand mouthful fillet is designed at the irregular core of core box and is lived and is expected；
B. during back-up sand, the aluminum is lived and expects to take away from core box, back-up sand mouthful is reserved；
C. the back-up sand in core box, when sand is filled out and flushed with core box top surface, stops back-up sand；
D. aluminum work material is placed on core box, firmly extruded, and ensure that aluminum work charge level is concordant with core box back-up sand face, it is ensured that
The degree of packing of core；
E. after core consolidation, take out aluminum and live and expect；Take core box apart, take out the core for retaining fillet.
Further, the step of making the aluminum work material is as follows：
A. design：Core box is designed according to the shape of core, in the case where retaining back-up sand mouthful fillet, aluminum is designed and lives and expect
Shape, aluminum lives material wall thickness in 15-20mm, aluminum live material side and core box between contact gap between 0.5-1mm；
B. cast：When casting aluminum work material, the aluminum lives the flatness expected within 0.5mm, the allowance of blank
Between reserved 5-7mm；
C. process：Lived according to aluminum and expect design drawing, made corresponding aluminum and live and expect mould, material progress of being lived to the aluminum
Processing, makes the aluminum work material of shaping；
D. pincers worker：Polishing aluminum, which is lived, expects surface so that aluminum, which is lived, expects that surface is smooth, and in aluminum work material over-assemble steel
The handle of system；
E. detect：Detect the processing dimension of aluminum work material.
Further, the aluminum described in above-mentioned steps c lives material design drawing according to material of being lived to aluminum work material wall thickness, aluminum
Contact gap, the requirement of the flatness of aluminum work material between side and core box, make different aluminums and live and expect design drawings.
Further, aluminum, which is lived, expects that design drawing makes corresponding aluminum according to the different aluminums work material design drawings being designed to
Material mould living.
The beneficial effects of the present invention are：The present invention ensure that the quality and shape of core, solve complicated core production
Difficult problem, and simplify manual operations, improve operating efficiency.
Brief description of the drawings
Fig. 1 is the sectional view of the present invention.
In figure：1st, aluminum is lived material, and 2, core box, 3, core.
Embodiment
Illustrate the embodiment of the present invention with reference to Figure of description.
With reference to Fig. 1, a kind of method of the fillet in the irregular back-up sand face of reservation, including make aluminum work material and make with not
The big step of core two of regular back-up sand face fillet is as follows：
（1）Make aluminum and live and expect that step is as follows：
A. design：Core box is designed according to the shape of core, in the case where retaining back-up sand mouthful fillet, aluminum is designed and lives and expect
Shape, aluminum lives material wall thickness in 15-20mm, aluminum live material side and core box between contact gap between 0.5-1mm；
B. cast：When casting aluminum work material, the aluminum lives the flatness expected within 0.5mm, the allowance of blank
Between reserved 5-7mm；
C. process：Lived according to aluminum and expect design drawing, made corresponding aluminum and live and expect mould, material progress of being lived to the aluminum
Processing, makes the aluminum work material of shaping；
D. pincers worker：Polishing aluminum, which is lived, expects surface so that aluminum, which is lived, expects that surface is smooth, and in aluminum work material over-assemble steel
The handle of system；
E. detect：Detect the processing dimension of aluminum work material.
（2）The core step for making the fillet with irregular back-up sand face is as follows：
A. an aluminum that can retain back-up sand mouthful fillet is designed at the irregular core of core box and is lived and is expected；
B. during back-up sand, the aluminum is lived and expects to take away from core box, back-up sand mouthful is reserved；
C. the back-up sand in core box, when sand is filled out and flushed with core box top surface, stops back-up sand；
D. aluminum work material is placed on core box, firmly extruded, and ensure that aluminum work charge level is concordant with core box back-up sand face, it is ensured that
The degree of packing of core；
