Embodiment Construction

[0010] A kind of gyroscope motor rotor casting process of the present invention, use equipment is 14OT cold chamber die-casting machine, accumulator is piston type, and accumulator pressure is placed on 12-15MPa, and the specific technological process of this invention is:

[0011] 1. Debug the die-casting machine and die-casting mold, the system pressure of the die-casting machine is 130T;

[0012] 2. The crucible is preheated at a temperature of 150-200°C, the aluminum ingot is smelted and purified at a temperature of 720-760°C, and the temperature is lowered to 700°C after refining;

[0013] 3. Die-casting mold pressure test 30-50 molds, make the mold temperature reach 220-250 ℃, clean the cavity and runner, and insert the rotor laminations in the oven to preheat to 75-80 ℃;

[0014] 4. Die-casting molding: Spray release agent in the cavity → mold closing → mold closing delay → injection → pressure holding delay → primary parting, punch and material handle separation → seco...

Abstract

The invention provides a casting technology for a gyroscope motor. In the invention, a 140T cold chamber die casting machine is selected; a central technological sprue is arranged; die-casting technological parameters such as aluminium melting temperature, mold temperature and the like can be controlled; simultaneously a strong release agent is used in the die casting technology, thus realizing the aim of manufacturing the gyroscope motor rotor by adopting a die casting process method. The mold design adopts a two-step parting way; multi-point material inlets can be fed from 6 small holes of an inserting part so that the aluminium alloy fills a mold cavity under high pressure and can be crystallized and solidified under high pressure. Before the product is produced, the die casting technology is compiled so that a die casting operator can adjust reasonable parameters, strictly comply with the technology to guide production, and ensure that the product has good organization compactability, has no shrunk holes, air holes and slag and has good mechanical performance. The casting technology has the advantages of reducing subsequent machining margin, saving material, reducing cost, avoiding secondary environmental pollution, eliminating potential safety hazard, and improving productivity.

Description

[0001] technical field [0002] The invention relates to the field of gyroscope motor manufacturing, in particular to an improved high-pressure casting process for the gyroscope motor rotor. Background technique [0003] As we all know, in the field of gyro motor manufacturing, there is a casting process for the rotor forming in the traditional gyro motor, which is completed by the method of vertical centrifugal casting. The specific process method is to inject the refined aluminum alloy book solution into the rotating mold, and through the high-speed operation of the casting machine, the molten aluminum alloy is fully filled into the gap between the rotor lamination and the pressure ring through the centrifugal force, and then cooled and solidified into shape . This process has obvious disadvantages. On the one hand, since the outer diameter of the rotor is only 30mm in diameter and the total length is less than 25mm, the surface of the casting using the centrifugal castin...
