Abstract
The invention discloses a rotor cast aluminum mold with multiple runners. The rotor cast aluminum mold comprises an upper mold, a middle mold and a lower mold; a rotor iron core is arranged in a cavity formed among the upper mold, the middle mold and the lower mold; the inner circle of the rotor iron core is connected with a false shaft; the upper mold is provided with an upper template; the lower mold is provided with a lower template; the middle mold is provided with a casting runner; the casting runner includes a taper section and a cylinder section; the taper section is communicated with an external runner; the cylinder section is communicated with the rotor iron core; and casting branches are symmetrically arranged in the connecting place of the taper section and the cylinder section. The casting runner is formed in the middle mold, and the casting branches are arranged on two sides of the casting runner, so that cast molten aluminum can be uniformly distributed in the rotor iron core from each direction, the distribution uniformity of the molten aluminum in each place of the rotor iron core is guaranteed, and the cast aluminum quality of the rotor is effectively improved.
Description
Technical field
The present invention 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, and relative to centrifugal aluminum casting, pressure cast aluminium has a characteristic that (1) at press casting procedure all the time, and pressure plays Main Function；(2) carrying out under pressure due to liquid metal filling process, rotor core can die casting in the cold state；(3) production efficiency is high, easily realizes 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, aluminum liquid enters from the casting runner of lower mold, and flow to rotor core under the effect of the pressure, this cast-aluminum die is to enter from lower mold due to aluminum liquid, when aluminum liquid moves toward upper mold direction from lower mold, 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.
Summary of the invention
The invention is intended to offer can make aluminum liquid be evenly distributed in rotor core everywhere, thus improves a kind of casting aluminum rotor mould with multiple flow passages of casting aluminum rotor quality.
The casting aluminum rotor mould with multiple flow passages in this programme, including upper mold, middle mold and lower mold, it is provided with rotor core in the chamber formed between upper mold, middle mold and lower mold, the inner circle of rotor core connects dummy shaft, cope match-plate pattern it is provided with at upper mold, lower bolster it is provided with at lower mold, middle mold offers casting runner, casting runner includes tapered section and cylindrical section, tapered section communicates with external flow passage, cylindrical section communicates with rotor core, is also symmetrically arranged with casting branch road in the joint of tapered section Yu cylindrical section.
The operation principle of this programme is: when rotor core is carried out cast aluminium, first rotor core is placed on by the chamber formed between upper mold, middle mold and lower mold, the aluminum liquid of casting is passed through the tapered section of casting runner, and through the cylindrical section entrance rotor core of casting runner, while aluminum liquid enters cylindrical section, part aluminum liquid is also by entrance casting branch road, and under the cylindrical section of casting runner and the common effect of 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 casting branch road is set 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 the uniformity of rotor core aluminum liquid everywhere distribution, 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 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 lower mold is 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 being attached by screw, 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.When cope match-plate pattern carries out coordinating installation with external rack, the installation seam of cope match-plate pattern being directed at the corresponding installation site of external rack, the location that can make cope match-plate pattern is simple and reliable.
