The mobility of potting syrup in casting process, so as to improve the quality of cast(ing) surface, prevent cast(ing) surface from producing fash.
The preceding coating spray treatment to mold inner chamber of core assembling is additionally included in step S3 mold processing.Mold inner chamber
The design of coating spray treatment improve the mobility of potting syrup in casting process
1 cast gate and 2 rising heads are provided with the top of casting model.In order to reduce the generation of bleb, and avoid miscellaneous
Thing enters to improve the quality of casting, and screen pack block is provided with cast gate.
Casting model is arranged on turning device in step S4 mould assembling cast, using manually or electrically or hydraulic means
Horizontally disposed turning device is driven, is rotated by 90 ° it, turning device and casting model can erect, after erectting upset,
Cast gate and rising head vertically upward, set pouring basin on cast gate.
Casting model upset is carried out by using turning device, is then poured into a mould under upright condition, cast can be made quiet
Pressure head improves about 150mm, solves product top of supply line and shrinkage porosity defect of contraction cavity easily occurs, while does not need big feeding head, produces
Product product yield improves 10~15%, improves finished product rate 6~8%, significantly reduces production cost and is improving matter
Realize on the basis of amount and pour into a mould vertically downward, realize that horizontal type erects pouring technique, by using this method, process is processed after can reducing
When product scrappage caused by bubble stomata etc., while improve mould strength and stability, uniformity, solve because of casting mold consolidation
Spend and low cause casting mold to make a concession product and the problem of shrinkage porosite rarefaction defect easily occur to be easily achieved consecutive solidification, be advantageous to casting pouring and coagulate
From upper and first feeding during Gu, the inherent quality of product is significantly improved, realizes gear case body castings production machinery
Change operation, improve production efficiency.
Cutting in step S5 includes cutting the rising head of gear-box box casting and the edge of gear case body casting is unnecessary
Corner angle, and in cutting process, cutting sheet is at 1~2mm of gear case body casting.
Corase grind includes the core print fash and rising head edge for handling gear case body casting surrounding；And fine grinding uses small polishing
Machine to being refined at the core print fash of gear case body casting, while scab to gear case body cast(ing) surface and inner chamber,
Scab, overlap, burr are handled.
The preferred embodiment of the present invention is these are only, is not intended to limit the invention, for the technology of this area
For personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
