Abstract
The invention discloses a casting and operating method of lap flow gates in a controlled manner. The method is characterized by comprising the following steps of: firstly preparing a mold; then smelting metal into metal liquid; casting the metal liquid after being dissolved; and finally taking off the mold, and inspecting the quality. The casting and operating method provided by the invention has the advantages that the preparation method is simple and is convenient to operate, the flow direction and the flow state of the metal liquid which enters a sectional cavity can be controlled, the local overheating problem of the flow gates can be overcome, and the phenomena of sand washing, splashing, air inspiration, oxidation and the like during the casting process can be solved.
Description
Technical field:
The present invention relates to a kind of method of operating that control overlap joint ingate is arranged.
Background technology:
At present; Along with science and technology is showing improvement or progress day by day; How in manufacture process, effectively reducing cost, promote quality, is the effort target of industry; Existing casting mode makes molten metal leave the type wall easily or rushes at the type wall or the core on ingate opposite, causes sand washing, splashes, phenomenon such as air-breathing and oxidation.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, a kind of method of operating that control overlap joint ingate is arranged is provided.
The object of the invention is realized through following technical scheme: a kind of method of operating that control overlap joint ingate is arranged may further comprise the steps:
A, preparation mould;
B, smelting metal liquid;
C, casting; The cast temperature scope is 1260 ℃～1300 ℃; Ingate outlet height equals the lap of splice on ingate and die cavity top, and the thickness at sprue gate is noted pushing off the slag less than 30mm during casting; The cast oral area of molding sand is answered tamping; Gradient is not with at the sprue gate, prevents sand washing, notes the flow of control molten metal;
D, take off grinding tool, check on the quality;
The present invention compared with prior art has the following advantages:
The foundry goods of the present invention through this processes can be controlled the problem of the flow direction that molten metal gets into die cavity, fluidised form, ingate hot-spot, solved sand washing in the casting cycle, splashes, phenomenon such as air-breathing and oxidation.
The specific embodiment:
In order to deepen to understanding of the present invention, will combine embodiment that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
The present invention relates to a kind of specific embodiment that the method for operating of control overlap joint ingate is arranged, may further comprise the steps: at first prepare mould, then Metal Melting is smelt molten metal; Cast after the molten metal dissolving, the cast temperature scope is 1260 ℃～1300 ℃, and ingate outlet height equals the lap of splice on ingate and die cavity top; The ingate number can be set number according to actual conditions, can disperse to be provided with, and the thickness at sprue gate is less than 30mm; Note pushing off the slag during casting, the cast oral area of molding sand is answered tamping, and gradient is not with at the sprue gate; Prevent sand washing, note the flow of control molten metal, for the foundry goods of thick massive plate class; For preventing that sand washing, burning into sand from can adopt the extraordinarily thick clay-bonded sand moulding of adding some coke grain, the casting mold residual moisture is controlled at below 0.5%, takes off grinding tool at last; Check on the quality; Through the foundry goods of this processes, can control the problem of the flow direction that molten metal gets into die cavity, fluidised form, ingate hot-spot, solved sand washing in the casting cycle, splashed, phenomenon such as air-breathing and oxidation.
