Description
Technical field
This utility model relates to casting aluminum rotor mould, a kind of casting aluminum rotor mould with multiple flow passages.
Background technology
At present, the cast aluminium processing mode of rotor mainly has pressure cast aluminium and centrifugal aluminum casting two kinds, relative to centrifugal casting
Aluminum, pressure cast aluminium has a characteristic that (1) at press casting procedure all the time, and pressure plays Main Function；(2) due to molten metal filing
Type process is carried out under pressure, and rotor core can die casting in the cold state；(3) production efficiency is high, easily realize mechanization,
Automatization, thus can reduce labor intensity.Therefore, pressure cast aluminium is applied the most extensive in terms of rotor processing.
The mould of currently used pressure cast aluminium is all to offer casting runner in lower mold, and aluminum liquid is from the casting stream of lower mold
Road enters, and flows to rotor core under the effect of the pressure, and this cast-aluminum die is to enter from lower mold due to aluminum liquid, aluminum liquid from
When lower mold is moved toward upper mold direction, often due to insufficient pressure causes being positioned at the rotor core near upper mold space easily occurs,
In turn result in rotor core aluminum liquid skewness everywhere, the ropy problem of cast aluminium of rotor.
Utility model content
This utility model is intended to offer can make aluminum liquid be evenly distributed in rotor core everywhere, thus improves casting aluminum rotor matter
A kind of casting aluminum rotor mould with multiple flow passages of amount.
The casting aluminum rotor mould with multiple flow passages in this programme, including upper mold, middle mold and lower mold, upper mold, middle mold and under
Being provided with rotor core in the chamber formed between mould, the inner circle of rotor core connects dummy shaft, is provided with cope match-plate pattern at upper mold,
Being provided with lower bolster at lower mold, offer casting runner in middle mold, casting runner includes tapered section and cylindrical section, tapered section with
External flow passage communicates, and cylindrical section communicates with rotor core, is also symmetrically arranged with casting in the joint of tapered section with cylindrical section
Road.
The operation principle of this programme is: when rotor core is carried out cast aluminium, first rotor core is placed on by upper mold, in
In the chamber formed between mould and lower mold, the aluminum liquid of casting is passed through the tapered section of casting runner, and through the cylinder of runner of casting
Section enters rotor core, and while aluminum liquid enters cylindrical section, part aluminum liquid is also by entrance casting branch road, at casting runner
Under the common effect of cylindrical section and casting branch road, the aluminum liquid of casting is evenly distributed in rotor core.
Casting runner is arranged in middle mold by this programme, and arranges casting branch road in the both sides of casting runner, so that
The aluminum liquid of casting can be evenly distributed in rotor core from all directions, it is ensured that it is uniform that rotor core aluminum liquid everywhere is distributed
Property, effectively raise the cast aluminium quality of rotor.
Further, offering upper groove and low groove respectively at the two ends of middle mold, upper mold stretches in upper groove, and lower mold stretches into
In low groove.When carrying out the assembling of each mould, middle mold is first installed, then upper mold is put in the upper groove of middle mold, finally by lower mold
Put in the low groove of middle mold, thereby may be ensured that in installation process the reliability of position between each mould.
Further, upper mold is attached by four screws that circumference is uniform with cope match-plate pattern.Upper mold and cope match-plate pattern are passed through
Screw is attached, and screw is a kind of common connector, has that switching performance is reliable and the advantage of easy installation and removal.
Further, cope match-plate pattern is further opened with the installation seam carrying out coordinating with external rack.By cope match-plate pattern with outer
When portion's frame carries out coordinating installation, the installation seam of cope match-plate pattern is directed at the corresponding installation site of external rack, cope match-plate pattern can be made
Location simple and reliable.
