Abstract
The invention discloses a motor rotor cast aluminum mold with a guide mechanism. The cast aluminum mold comprises an upper mold, a middle mold and a lower mold; a rotor iron core is arranged in a space formed among the upper mold, the middle mold and the lower mold; the middle part of the rotor iron core is connected with a false shaft; the upper mold is provided with an upper template at the upper part; the lower mold is provided with a lower template at the lower part; the lower mold is provided with a casting runner; two guide columns are symmetrically arranged on the upper template; a guide hole is formed in the middle mold; the lower template is provided with projections corresponding to the guide columns in position; guide grooves are formed in the projections; and when the lower mold is closed, the guide grooves can move along the guide columns. The cast aluminum mold can realize accurate positioning of the middle mold and the lower mold in the whole mounting process so as to improve the cast aluminum quality of the rotor iron core.
Description
Technical field
The present invention relates to cast-aluminum die, a kind of electric motor rotor aluminium casting mould with guiding mechanism.
Background technology
The rotor of motor includes stacked stalloy, in stalloy end, also die casting has aluminum termination, also having coupling part between the aluminum termination at two ends, coupling part is connected by the plug hole of stalloy, and stalloy is just coupled together by such aluminum termination, coupling part becomes the rotor of motor.
When mounted, upper mold, middle mold and lower mold the most often do not have guide frame to electric motor rotor aluminium casting mould, and this installation site that will likely result between each mould is inaccurate, in turn results in the mass defect of cast-aluminum rotor.
Summary of the invention
The invention is intended to provide a kind of electric motor rotor aluminium casting mould with guiding mechanism that can realize and being accurately positioned between each mould.
The electric motor rotor aluminium casting mould with guiding mechanism in this programme, including upper mold, middle mold and lower mold, in upper mold, the space that middle mold and lower mold are formed is provided with rotor core, connect in the middle part of rotor core and have dummy shaft, it is provided with cope match-plate pattern on the top of upper mold, it is provided with lower bolster in the bottom of lower mold, lower mold is further opened with runner of casting, cope match-plate pattern is symmetrically arranged with centered by dummy shaft two leads, middle mold offers the pilot hole passed through for lead, position corresponding with lead on lower bolster is provided with projection, projection offers gathering sill, lower mold is when carrying out matched moulds, gathering sill can move along lead.
The principle of this programme is: when carrying out the cast aluminium of rotor core, upper mold is first installed, rotor core is arranged on dummy shaft, then middle mold is enclosed within the cylindrical of rotor core, lower mold is finally installed, after installing, by aluminum liquid input casting runner, and enter in rotor core, and then complete the cast aluminium of rotor core.
During the installation of underway mould, make the lead of upper mold through the pilot hole in middle mold, when installing lower mold, make the gathering sill alignment guide post of lower mold, the cast-aluminum die of this programme is in whole installation process, being accurately positioned of middle mold and lower mold can be realized, thus improve the cast aluminium quality of rotor core.
Further, rotor core and dummy shaft use the mode of flat key to be attached.Flat key connect mode is easy for installation and dependable performance.
Further, upper mold is provided with exhaust passage, lower mold is provided with lower exhaust passage.When carrying out casting aluminum rotor, the air in rotor core can by discharging in upper exhaust passage and lower exhaust passage, thus the cast aluminium that causes of the existence effectively reducing air occurs split the problems such as bar.
Further, upper exhaust passage includes that upper air-vent and upper air discharge duct, lower exhaust passage include lower steam vent and lower air discharge duct, and upper air-vent is the upper air-vent with tapering, and lower steam vent is the lower steam vent with tapering.Upper air-vent and lower steam vent with tapering can improve air speed when steam vent is discharged, thus improve the expulsion efficiency of air.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
