Abstract
The invention relates to a large length-diameter flow channel mechanism of a 4AT automatic-transmission gear box. The flow channel mechanism comprises a flow channel material cake, main flow channels and a branch flow channel, the flow channel material cake is arranged in the middle of one side of a casting of a box and is connected with one side of the casting of the box through the two forked main flow channels, one end of one main flow channel is connected with one end of the branch flow channel, the branch flow channel extends to the other side of the casting of the box along the outside of the casting of the box, the side, close to the casting of the box, of the branch flow channel is connected with the casting of the box through multiple small flow channels. The length diameter of the flow channel mechanism is large, an aluminum material enters a cavity of a die casting die from a difficult forming point of the casting, aluminum passing through a fine core of a die is reduced, a thermal center problem is effectively solved and quality and volume production are guaranteed.
Description
Technical field
The present invention relates to die casting field, particularly relate to a kind of 4AT automatic catch gearbox big L/D ratio runner mechanism.
Background technology
At present, automobile automatic gear gearbox body die-casting die casting system, general only from part apart from expecting the valve plate charging that cake is nearer, with reference to foreign technology, because filling after foundry goods charging is from the charging more nearby of distance material cake, and the complex structure of cast product own, volume is larger, product weight reaches 12.7Kg, adds that there is 21Kg in the row of watering.During filling, easy aluminium is expected and is reached inconsistent, and easily sealed at edge, air cannot be got rid of, and pith produces a large amount of sbrinkage blowhole, even crackle.Casting quality cannot ensure, produces a large amount of product defectses, and die casting percent defective is high, for a long time, is a die casting difficult problem, has occurred cannot allowing in a large number the problem of New Car.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of 4AT automatic catch gearbox big L/D ratio runner mechanism, the long-neck of runner is larger, aluminium material enters die casting die cavity from the shaping difficult point of foundry goods, reduce the thin core position of mould and cross aluminum amount, efficiently solve thermal center problem, ensure that quality and production.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of 4AT automatic catch gearbox big L/D ratio runner mechanism, comprise runner material cake, sprue and runner, described runner material cake is arranged in a middle side part of box casting, it is connected with the side of box casting by the sprue of two bifurcateds, wherein one end of a sprue is connected with one end of runner, described runner extends to the opposite side of box casting along the outside of box casting, described runner is connected with box casting by several small flow channels near the side of box casting.
Supplement as one of the present invention, described runner is connected with the valve body position of box casting by vertical runner near the side of box casting.
Supplement as another kind of the present invention, one end of another root sprue is also connected with box casting by vertical runner.
Runner described in this patent has larger draw ratio, the opposite side that whole foundry goods extends to foundry goods is walked around from material cake, and be connected with more difficult position shaping on foundry goods by small flow channels, when foundry goods is filled, easily wrap up in gas, easily produce sbrinkage blowhole problem, the slag heat-extraction system of reasonable Arrangement reduces the appearance of the problem such as cold shut, blackout, thus improve casting quality, improve casting yield.
beneficial effect
The present invention relates to a kind of 4AT automatic catch gearbox big L/D ratio runner mechanism, the long-neck of runner is larger, and aluminium material enters die casting die cavity from the shaping difficult point of foundry goods, reduces the thin core position of mould and crosses aluminum amount, efficiently solve thermal center problem, ensure that quality and production.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
As shown in Figure 1, embodiments of the present invention relate to a kind of 4AT automatic catch gearbox big L/D ratio runner mechanism, comprise runner material cake 2, sprue 1 and runner 4, described runner material cake 2 is arranged in a middle side part of box casting 3, it is connected with the side of box casting 3 by the sprue 1 of two bifurcateds, wherein one end of a sprue 1 is connected with one end of runner 4, described runner 4 extends to the opposite side of box casting 3 along the outside of box casting 3, described runner 4 is connected with box casting 3 by several small flow channels 5 near the side of box casting 3.
Described runner 4 is connected with the valve body position of box casting 3 by vertical runner 7 near the side of box casting 3.
One end of another root sprue 1 is also connected with box casting 3 by vertical runner 7.
Runner described in this patent has larger draw ratio, the opposite side that whole foundry goods extends to foundry goods is walked around from material cake, and be connected with more difficult position shaping on foundry goods by small flow channels, when foundry goods is filled, easily wrap up in gas, easily produce sbrinkage blowhole problem, the slag heat-extraction system of reasonable Arrangement reduces the appearance of the problem such as cold shut, blackout, thus improve casting quality, improve casting yield.
