Embodiment Construction

[0008] The invention adopts conventional plunger lubricant supply equipment and electrostatic spraying method for spraying.

[0009] Mold release agent spraying:

[0010] Before spraying the mold release agent, each cavity of the mold should be blown with a compressed air gun. Then pour less than 80 pounds of water-based powder or granular lubricant containing zinc stearate sold on the market into the powder barrel of the electrostatic spray gun spraying device, and the water-free granule or powder lubricant is compressed by compressed air. The release agent is vulcanized and evenly sprayed to the surface of each molding and parting surface in the mold through an electrostatic spray gun.

[0011] The input voltage of the electrostatic spray gun spraying device is 220V, 50HZ; it is necessary to ensure that the oil content of the input compressed air is less than 0.1p.p.m. and the water content is less than 1.3 g / m3; the input compressed air pressure is 4-7bar.

[0012] Plunge...

Abstract

The invention relates to the application of moisture-free basis powder or grain lubricant in die-casting pure copper and the cooper squirrel-cage rotor of high copper containing alloy induction motor, which belongs to nonferrous metal process technology field. The invention is the application of making moisture-free basis powder containing zinc stearate or grain lubricant as punch or surge chamber lubricant and the application of making moisture-free basis powder containing zinc stearate or grain lubricant as demoduling agent of the module. The invention adopts regular plunger piston lubricant supply equipment and static blow gun spray finishing way to spay finishing. The practical application shows that: with adopting the application in the invention, the qualification rate of the copper rotor product and the service life of the die-casting device are both improved obviously.

Description

Technical field: [0001] The invention relates to the application of water-free powdery or granular lubricant in die-casting pure copper and high-copper-containing alloy induction motor copper squirrel cage rotor, which belongs to the technical field of non-ferrous metal processing. Background technique: [0002] In the prior art, water-based lubricants are used to lubricate parts such as die-casting molds. Since the water-based lubricant will not only reduce the temperature of the preheating parts, the preheating parts will be in a state of intermittent cold and hot, which will easily cause thermal fatigue damage of the preheating parts, and will also aggravate the generation of thermal cracks. Therefore, in the die-casting process of copper squirrel cage rotors for induction motors made of pure copper and high-copper alloys, the selection of mold release agents and plunger lubricants required for molds and pressure chambers is very important, which will affect the quality o...
