Abstract
The invention relates to the technical field of diesel locomotives, in particular to a ductile cast iron stable-pressure box casting device for an internal combustion engine. The device comprises a casting and sand cores, wherein the sand cores are uniformly distributed in an inner cavity of the casting; and a main sprue, a main cross gate, a cross gate and an ingate are arranged in the sand cores. The trapezoidal cross gate and the flat and thin rectangular ingate are communicated as a whole to form a height fall, so that slag upwards floating to the top surface of the cross gate is not in a sucking area of the ingate, and is prevented from entering a molding cavity; the cross gate and the ingate are both arranged at the bottoms of the sand cores, are positioned in the casting, and are lower than the bottom surface of the casting; and molten metal is short in flowing distance in the molding cavity, so that such defects as cold clamping and splashing of the casting can be effectively reduced, the size of a sand box can be reduced, the use level of molding sand is decreased, and the production cost is reduced. Metal enters the molding cavity from the bottom of the casting, so that the mold filling is stable without generating splashing and oxidization, and the slag can be effectively stopped from entering the molding cavity to prevent the slag clamping defect.
Description
Technical field
The present invention relates to technical field of diesel locomotive, especially a kind of internal combustion engine spheroidal graphite cast-iron pressurizer tank apparatus for pouring.
Background technology
Tradition spheroidal graphite cast-iron pressurizer tank adopts side teeming or parting gating, during cast, to fill type not steady for iron liquid, easy generation is splashed oxidation, causes foundry goods splashings defect, if cup is not full of or stops foundry goods also may be made to form the defects such as cold folder and slag inclusion during cast.
Summary of the invention
Easily producing to overcome existing pressurizer tank running gate system oxidation of splashing, causing the deficiency of foundry goods splashings defect, the invention provides a kind of internal combustion engine spheroidal graphite cast-iron pressurizer tank apparatus for pouring.
The technical solution adopted for the present invention to solve the technical problems is: a kind of internal combustion engine spheroidal graphite cast-iron pressurizer tank apparatus for pouring, comprise foundry goods and core, core is evenly distributed on the inner chamber of foundry goods, is provided with total sprue, total cross gate, cross gate and ingate in core.
According to another embodiment of the invention, comprise total sprue further tapered, be vertically set on the central authorities of core.
According to another embodiment of the invention, comprise the bottom that total cross gate is arranged on core further, with total sprue UNICOM.
According to another embodiment of the invention, comprising cross gate is further semi-closed structure, and cross section is trapezoidal, is connected in the periphery of total cross gate.
According to another embodiment of the invention, comprise ingate further rectangular, comparatively cross gate is low, is evenly distributed on the periphery of cross gate.
The invention has the beneficial effects as follows, the ingate UNICOM of the design cross gate of trapezoidal shape and flat thin rectangular shape shape is integral, form high low head, ensure that the slag floating to cross gate end face is not in the Xi Dong district of ingate, prevent slag from entering die cavity, cross gate is semi-closed structure, can reduce the flowing velocity of molten metal, makes molten metal flow steadily in cross gate; Cross gate and ingate are all arranged in the bottom of core, are positioned at the inside of foundry goods, and lower than the bottom surface of foundry goods, molten metal flow distance in die cavity is short, effectively can reduce the defects such as the cold folder of foundry goods, splashings, can also reduce sandbox size, reduce molding sand consumption, reduce production cost.Molten metal enters total cross gate from total sprue, enter cross gate and ingate again, finally bottom foundry goods, enter die cavity, fill type steady, can not produce and splash and oxidation, only after cross gate is full of, just can enter die cavity, the dimension scale relation regardless of running gate system is open or closes, also no matter whether cup is full of or interrupted pour, in whole casting process, cross gate remains full state, can effectively stop that slag enters die cavity, prevent dreg defect.
