Abstract
The present invention relates to the modified technique of fuel tank cast casting.In modeling process, main running channel is set vertically downward along sprue channel open, horizontal running channel is set between the fuel tank sand mold chamber upper surface of fuel tank casting and main running channel, there is four bottoms leg chamber in fuel tank sand mold bottom of chamber face, the adjacent two bottoms leg chamber of a line sets cross gate between main running channel respectively, adjacent two bottoms leg chamber sets ingate between main running channel respectively in addition, and ingate is located at fuel tank sand mold chamber lower section；During cast, molten steel enters fuel tank sand mold chamber from top to down by main running channel, horizontal running channel, and molten steel horizontally enters into fuel tank sand cavity bottom by main running channel, cross gate, and molten steel is entered inside fuel tank sand mold chamber from bottom to up by main running channel, ingate.The present invention avoids fuel tank upper surface from stomata and shrinkage cavity occur；Fuel tank casting bottom surface bottom leg chamber position and bottom surface centre position is avoided the impurity such as stomata and sand slag blister occur.
Description
Technical field
The invention belongs to fuel tank casting field, the specifically to modified technique of fuel tank cast casting.
Background technology
Fuel tank casting is commonly used in machinery production, in existing pouring technology, gas is had at plane on fuel tank casting
Hole and shrinkage cavity, bottom surface bottom leg chamber position, bottom surface middle part have the defects such as stomata, sand slag blister, after making moulding by casting
Fuel tank is easily damaged, and oxidation resistance is poor, and low intensity, service life is short.
The content of the invention
In order to solve the problems, such as prior art, the invention provides the modified technique of fuel tank cast casting.
The modified technique of fuel tank cast casting, casting technique includes moulding, and mould assembly, cast, knockout, cleaning, ball blast is prevented
Rust.In modeling process, main running channel is set vertically downward along sprue channel open, the fuel tank sand mold chamber upper surface and main running channel of fuel tank casting it
Between horizontal running channel is set, there is four bottoms leg chamber in fuel tank sand mold bottom of chamber face, the adjacent two bottoms leg chamber of a line respectively with main running channel
Between cross gate is set, two bottoms leg chamber adjacent in addition sets ingate between main running channel respectively, and ingate is located at fuel tank
Sand mold chamber lower section；During cast, molten steel enters fuel tank sand mold chamber from top to down by main running channel, horizontal running channel, and molten steel is poured by master
Road, cross gate horizontally enter into fuel tank sand cavity bottom, and molten steel is entered in fuel tank sand mold chamber from bottom to up by main running channel, ingate
Portion.Screen pack is set on main running channel.The entrance of horizontal running channel sets screen pack.Horizontal running channel is two.Horizontal running channel, cross gate
And ingate is earthenware.
The beneficial effects of the invention are as follows：Horizontal running channel is set in fuel tank sand mold chamber upper surface, molten steel can be made from top to bottom
Fuel tank sand mold chamber is flowed into, makes fuel tank sand mold chamber inside upper and lower temperature difference small, it is to avoid stomata and shrinkage cavity occurs in fuel tank upper surface；Fuel tank sand
Die cavity bottom surface has four bottoms leg chamber, and molten steel two bottoms leg chamber adjacent on one side therefrom is horizontally entered into fuel tank sand mold chamber, steel
The water two bottom leg chamber adjacent from another side is entered in fuel tank sand mold chamber from bottom to up, i.e., molten steel is returned over from bottom surface, makes fuel tank
The impurity in sand mold bottom of chamber Mian Ditui chambers will not be piled up, while bottom leg chamber can simultaneously enter molten steel, make molten steel in fuel tank sand mold chamber
Bottom surface carries out revolution flowing, makes fuel tank cast-internal structure evenly, stably, it is to avoid fuel tank casting bottom surface bottom leg chamber position and
There is the impurity such as stomata and sand slag blister in bottom surface centre position.Long lifespan, intensity is high, and oxidation resistance is strong, it is not easy to damage.

Specific embodiment
The modified technique of fuel tank cast casting, casting technique includes moulding, and mould assembly, cast, knockout, cleaning, ball blast is prevented
Rust.In modeling process, main running channel 2 is set vertically downward along sprue channel open 1, the upper surface of fuel tank sand mold chamber 8 and the master of fuel tank casting pour
Horizontal running channel 4 is set, and there is four bottoms leg chamber 7 bottom surface of fuel tank sand mold chamber 8, the two bottoms leg chamber 7 near main running channel is distinguished between road 2
Cross gate 5 is set between main running channel 2, and the two bottoms leg chamber 7 away from main running channel 2 sets ingate between main running channel 2 respectively
6, ingate 6 is located at the lower section of fuel tank sand mold chamber 8；During cast, molten steel enters fuel tank from top to down by main running channel 2, horizontal running channel 4
Sand mold chamber 8, molten steel horizontally enters into the bottom of fuel tank sand mold chamber 8 by main running channel 2, cross gate 5, and molten steel passes through main running channel 2, ingate
6 enter inside fuel tank sand mold chamber 8 from bottom to up.Screen pack 3 is set on main running channel 2.The entrance of horizontal running channel 4 sets screen pack 3.
Horizontal running channel 4 is two.Horizontal running channel 4, cross gate 5 and ingate 6 are earthenware.
