Abstract
The invention discloses a method for retaining a circular angle of an irregular sand filling surface. The method is characterized by comprising two steps of manufacturing of an aluminum living material and manufacturing of a sand core having the circular angle of the irregular sand filling surface. In the step of manufacturing the aluminum living material, the wall thickness of the aluminum living material is within 15-20 mm; a gap between the aluminum living material and a core box is within 0.5-1 mm; the flatness of the aluminum living material is within 0.5 mm; and the machining allowance of a blank is reserved within 5-7 mm; in the step of manufacturing the sand core having the circular angle of the irregular sand filling surface, the aluminum living material is put on the core box, and is extruded tightly; the surface of the aluminum living material and the sand filling surface of the core box are leveled to guarantee the compactness of the sand core; after the sand core is compacted, the aluminum living material is taken out; and the core box is disassembled to take out the sand core retained with the circular angle. The method has the beneficial effects of guaranteeing the quality and the shape of the sand core, solving the problem of production difficulties of complicated sand cores, simplifying the manual operation and improving the working efficiency.
Description
Technical field
The present invention relates to field of machining, particularly relate to a kind of method retaining the fillet in irregular back-up sand face.
Background technology
During core box sand: the out-of-shape in the back-up sand hole of core box, utilize stragith edge to ensure that the quality in core back-up sand face can not use.The back-up sand mouth source of some core box needs to make fillet, can not ensure the quality of core back-up sand actinal surface by the method for stragith edge, needs design a kind ofly can either ensure the method that complicated back-up sand face can retain again the fillet of back-up sand mouth under these circumstances.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of method retaining the fillet in irregular back-up sand face, this invention can ensure quality and the shape of core, solves complicated core and produces difficult problem, and simplify manual operations, improve operating efficiency.
A kind of method retaining the fillet in irregular back-up sand face:
Comprise the following steps:
A. the aluminum material alive that can retain back-up sand mouth fillet is designed at the irregular core place of core box;
B., during back-up sand, material of being lived by described aluminum is taken away from core box, reserves back-up sand mouth;
C. back-up sand in core box, until sand fill out flush with core box end face time, stop back-up sand;
D. material of being lived by aluminum is placed on core box, firmly extruding, and ensures that aluminum charge level alive is concordant with core box back-up sand face, guarantees the degree of packing of core;
E., after core consolidation, aluminum material alive is taken out; Take core box apart, take out the core retaining fillet.
Further, the step making described aluminum material alive is as follows:
A. design: according to the profile design core box of core, when retain back-up sand mouth fillet, design aluminum live material shape, aluminum live material wall thickness at 15-20mm, aluminum live material side and core box between contact gap between 0.5-1mm;
B. cast: when casting aluminum is lived and expected, the flatness of described aluminum material alive is within 0.5mm, and the allowance of blank is reserved between 5-7mm;
C. process: foundation aluminum material alive design drawing, make corresponding aluminum material alive mould, described aluminum material alive is processed, make shaping aluminum material alive;
D. pincers worker: polishing aluminum material surface alive, makes aluminum material alive smooth surface smooth, and on aluminum material alive, assembles the handle of steel;
E. detect: the processing dimension detecting aluminum material alive.
Further, aluminum described in above-mentioned steps c material design drawing of living to be lived the requirement of flatness of material according to live contact gap between the side of material and core box, aluminum of material wall thickness of living to aluminum, aluminum, makes different aluminums and lives and expect design drawing.
Further, aluminum is lived and is expected that design drawing makes corresponding aluminum material alive mould according to the different aluminums material alive design drawing be designed to.
Beneficial effect of the present invention is: the present invention can ensure quality and the shape of core, solves complicated core and produces difficult problem, and simplify manual operations, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention.
In figure: 1, aluminum is lived material, 2, core box, 3, core.
Detailed description of the invention
Below in conjunction with Figure of description, the specific embodiment of the present invention is described.
Composition graphs 1, a kind of method retaining the fillet in irregular back-up sand face, comprises the large step of core two making aluminum material alive and make with irregular back-up sand face fillet, as follows:
(1) aluminum material alive step is made as follows:
A. design: according to the profile design core box of core, when retain back-up sand mouth fillet, design aluminum live material shape, aluminum live material wall thickness at 15-20mm, aluminum live material side and core box between contact gap between 0.5-1mm;
B. cast: when casting aluminum is lived and expected, the flatness of described aluminum material alive is within 0.5mm, and the allowance of blank is reserved between 5-7mm;
C. process: foundation aluminum material alive design drawing, make corresponding aluminum material alive mould, described aluminum material alive is processed, make shaping aluminum material alive;
D. pincers worker: polishing aluminum material surface alive, makes aluminum material alive smooth surface smooth, and on aluminum material alive, assembles the handle of steel;
E. detect: the processing dimension detecting aluminum material alive.
(2) making is as follows with the core step of the fillet in irregular back-up sand face:
A. the aluminum material alive that can retain back-up sand mouth fillet is designed at the irregular core place of core box;
B., during back-up sand, material of being lived by described aluminum is taken away from core box, reserves back-up sand mouth;
C. back-up sand in core box, until sand fill out flush with core box end face time, stop back-up sand;
D. material of being lived by aluminum is placed on core box, firmly extruding, and ensures that aluminum charge level alive is concordant with core box back-up sand face, guarantees the degree of packing of core;
E., after core consolidation, aluminum material alive is taken out; Take core box apart, take out the core retaining fillet.
