Description
Technical field
The utility model is related to a kind of casting technique side of the shell of the medium-and-large-sized electronic suite of railway locomotive dynamical system
Method, belongs to motor housing manufacturing technology field.
Background technology
Motor used in the dynamical system of railway freight-car locomotive belongs to large-size machine series, and its shell is typically common
The steel-casting of material, it is domestic to add cold core process to be produced using traditional fat hardened sodium silicate sand or furan resin-sand mostly,
Casting burning into sand crackle is an eternal insurmountable problem, a large amount of to lean on repeatedly repair welding repeatedly and multiple heat treatment to solve, cost
Height, long in time limit, quality is unreliable, and hidden danger is big, to be difficult into international market, it is impossible to the high-quality requirement of large-size machine in the world
High-end product competition.
The content of the invention
The purpose of this utility model is：A kind of railway locomotive high capacity motor shell running gate system is provided, it is existing to solve
Have in railway locomotive motor housing manufacturing process, the problem of casting burning into sand crackle occur can not solve all the time, cause production cost
Height, long in time limit, quality is unreliable, and hidden danger is big, it is impossible to asking that the high-end product of the high-quality requirement of large-size machine in the world is competed
Topic.
To solve the above problems, intending using such a railway locomotive high capacity motor shell running gate system, with realization
Casting technique is stated, the running gate system is that formula running gate system is returned at the bottom with 3 or more than three uniform ingates, is conducive to
Casting bottom temp is uniform, and pulls reinforcing to casting bottom solidification forming, has to the deformation for preventing cylindrical casting
Certain effect.Preferably, the running gate system is the integral type running gate system that rising pouring cross pouring belt anti-deforming structure is combined, including
Vertical running channel and vertical running channel lower end and the horizontal running channel being connected with vertical running channel are arranged at, horizontal running channel is four to constitute crosses
The running channel that shape distribution is set, vertical running channel is arranged at four groups of running channels and constitutes criss-cross middle part.
In foregoing running gate system, the annular being connected successively with four groups of running channels is additionally provided with the upside of horizontal running channel and is poured
Road groove；
In foregoing running gate system, horizontal running channel is flat running channel, and horizontal running channel is by being communicated to the one of vertical running channel
Hold the pouring gate structure to the other end gradually wide formula；
In foregoing running gate system, the upper end of vertical running channel is provided with funnel shaped sprue cup, and vertical running channel and sprue cup are equal
For complete ceramic pipe composite structure, horizontal running channel is to be segmented the superimposed core being made by hardening process by multigroup, running gate system by
Vertical running channel and horizontal running channel assemble.
Compared with prior art, the utility model enables to casting formation consecutive solidification, by selecting different sand kinds
Combination and the design of casting technique running gate system solve the large-size machine housing casting that Conventional processing methods can not be fully solved
The castability problems such as burning into sand, crackle and stator component location guide gross distortion that part is frequently occurred, by the repair welding rate repeatedly of casting
Control is within 2%-5%.Make the time processing qualification rate of its casting in 95%-98%, improve and stablize the quality of casting.
