Abstract
The utility model relates to a durable cast-aluminum rotor die-casting die. The durable cast-aluminum rotor die-casting die is composed of an upper die, a lower die, a die body and an upper gland, wherein the die body is embedded between the upper die and the lower die; the upper gland is placed above the upper die; the upper die is composed of an upper die set on the outer portion, an upper die core on the inner portion and an upper anti-expansion hoop arranged in the middle portion, the upper die set, the upper die core and the upper anti-explosion hoop are fixedly integrated, and a lower die core inner plane is formed by the upper top surface of the lower die core. The durable cast-aluminum rotor die-casting die is characterized in that a pressure reduction plane is arranged in the center of the lower die core inner plane. The durable cast-aluminum rotor die-casting die has the advantages of being scientific and reasonable in structural design, firm, durable, long in service life, capable of reducing cost investment and effectively improving production efficiency and the like, and is innovative.
Description
Technical field
The utility model belongs to the motor manufacturing equipment field, particularly a kind of durable cast-aluminum rotor die-casting mold tool.
Background technology
Cast-aluminum rotor is important parts commonly used in motor.In the cast-aluminum rotor production process, rotor core to be positioned in the cast-aluminum rotor die-casting mold tool to pour into a mould and fill with aluminium, before aluminium is filled with in cast, at first to eliminate sheet that the rotor chip causes because of burrs on edges and the gap between sheet by pressurization, the rotor chip tightly is superimposed.When pressurization, the lower mold core of cast-aluminum rotor mould can be born pressure simultaneously.The cast-aluminum rotor die-casting mold tool of conventional design, lower mold core is except die cavity, and what with punching, contact is same plane, it is the lower mold core inner plane, this lower mold core inner plane centre is the position that lower mold core is the weakest, and it is relatively large that pressure is born in lower mold core inner plane centre, under the repeated action of pressure, lower mold core inner plane centre will soon produce distortion, form the dish shape of central concave, along with access times increase, distortion is aggravation gradually, until the cracking, scrap, cause service life shorter.The frequent lower mold core of changing, not only strengthen cost and drop into, and affect to a certain extent production efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of lower mold core be shaped with decompression Plane, can reduce the lower mold core centre stressed, effectively extend lower mold core service life, durable cast-aluminum rotor die-casting mold tool that Cost reduction drops into, effectively enhances productivity.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of durable cast-aluminum rotor die-casting mold tool, by patrix, counterdie, mold, upper press cover forms, mold is flush-mounted in patrix, in the middle of counterdie, upper press cover is positioned on mold, patrix is by top mold frame, upper mold core, upper anti-swollen hoop forms, upper mold core is interior, top mold frame outside, upper anti-swollen hoop is fixedly mounted with and is integrated between two parties, counterdie is by lower mold holder, lower mold core, anti-swollen hoop forms down, lower mold core is interior, lower mold holder outside, anti-swollen hoop is fixedly mounted with and is integrated between two parties down, the upper end face of described lower mold core forms a lower mold core inner plane, it is characterized in that: the centre of described lower mold core inner plane is shaped with decompression Plane.
And the height of described decompression Plane is lower than lower mold core inner plane 0.15-0.25mm.
Advantage of the present utility model and beneficial effect are:
1. this durable cast-aluminum rotor die-casting mold tool, its lower mold core centre is shaped with decompression Plane, can reduce the stressed of lower mold core centre, effectively extends lower mold core service life.
This durable cast-aluminum rotor die-casting mold sign an undertaking real durable, but Cost reduction drop into, effectively enhance productivity.
3. this durable cast-aluminum rotor die-casting mold lamps structure design science is reasonable, but has the advantages such as durable, that the long service life Cost reduction drops into, effectively enhance productivity, and is a kind of durable cast-aluminum rotor die-casting mold tool with higher innovation.
The accompanying drawing explanation
Fig. 1 is the utility model assembling schematic diagram
Anti-swollen hoop, 9-rotor core, 10-lower mold core, 11-decompression Plane, 12-lower mold core inner plane under 1-top mold frame, the upper anti-swollen hoop of 2-, 3-upper mold core, 4-armature spindle, 5-upper press cover, 6-mold, 7-lower mold holder, 8-.
The specific embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The smooth and easy cast-aluminum rotor die-casting mold tool of a kind of exhaust, be comprised of upper die and lower die, mold 6, upper press cover 5, and mold is flush-mounted in the middle of upper die and lower die, and upper press cover is positioned on mold; Patrix, be comprised of top mold frame 1, upper mold core 3, upper anti-swollen hoop 2, upper mold core interior, top mold frame outside, on anti-swollen hoop be fixedly mounted with and be integrated between two parties; Counterdie, be comprised of lower mold holder 7, lower mold core 10, lower anti-swollen hoop 8, lower mold core interior, lower mold holder outside, lower anti-swollen hoop is fixedly mounted with and is integrated between two parties; Described lower mold core, on it, end face forms a lower mold core inner plane 12, and lower mold core inner plane centre is shaped with decompression Plane 11, and the decompression Plane height is lower than lower mold core inner plane 0.15-0.25mm.
Operation principle of the present utility model is:
While carrying out the cast-aluminum rotor cast, lower anti-swollen hoop, mold, the lower mold core of the durable cast-aluminum rotor die-casting mold of the utility model first are assembled into to counterdie successively, mold is positioned on the bed die core, the armature spindle 4 and the rotor core 9 that are set in one are positioned in mold, top mold frame, upper mold core, upper anti-swollen hoop first are assembled into to patrix, upper press cover is positioned over mold core top, and by mold core gland on mold; When exerting pressure to rotor core, pressure is delivered to the lower mold core inner plane by the rotor chip, and the pressure that lower mold core inner plane bear rotor core transmits, owing in lower mold core inner plane centre, being shaped with decompression Plane, the pressure that bear in the lower mold core centre reduces, thereby the distortion of lower mold core centre is alleviated greatly, make lower mold core more durable, extend service life, need not frequently change lower mold core, like this, not only Cost reduction drops into, and can enhance productivity to a certain extent.
