Abstract
The invention relates to technical field adopting BMC to perform die pressing shaft production, especially a die pressing process of an improved electric machine rotor die pressing shaft, which is characterized in that the steps comprise heating the cleaned rotating shaft with temeprature at 80-120 DEG C and keeping warm at least 0.5 hour, putting the rotor core and the preheated rotating shaft into the die pressing mould, and putting the BMC materials into material charmber to die pressing press. The temepratures of the part and the mould can be reduced from 180 DEG C to 100 DEG C in winter by the auxiliary heating means, thereby shortening about 15 seconds of filling and forming the die pressing plastics, and reducing the production cycle and production cost.
Description
[technical field]
The present invention relates to adopt BMC to carry out the technical field that the mold pressing axle is produced, specifically a kind of mould pressing process of improved rotor mold pressing axle.
[background technology]
Adopting thermoset plastics BMC to make the motor shaft insulation is one-shaping technique, be used for using double insulated motor, have characteristics such as cost is low, stable insulation, but owing to be to use mould pressing technology to need special equipment and mould, the higher mould of precision costs an arm and a leg, must make full use of and could reduce cost to greatest extent, be the effective method that reduces cost and shorten the production cycle.
[summary of the invention]
Purpose of the present invention overcomes the deficiencies in the prior art exactly, and the cycle that shortens mold pressing is heated in rotating shaft in advance, realizes the reduction of cost.
For achieving the above object, design a kind of mould pressing process of improved rotor mold pressing axle, it is characterized in that: (1) rotating shaft is cleaned: with gasoline or alcohol that the rotating shaft surface clean is clean; (2) rotating shaft preheats: with the rotating shaft that cleans up heating, heating and temperature control is at 80-120 ℃, and insulation at least 0.5 hour; (3) mold pressing: molding die is put in the rotating shaft of rotor core and preheating, the BMC material is put into the matched moulds pressurization of material chamber, carry out injection moulding; (4) clear up finished product: take out the unnecessary plastics in cleaning surface, back after mold pressing is finished, finished product.Described being heated to be adopts baking oven to heat.
The present invention compares with prior art, utilizes the assistant heating means that the temperature difference of part and mould is reduced, and 180 during by winter, degree reduced to about 100 degree, filling, the moulding equal time of moulded plastic have been reduced thus, can shorten about 15 seconds, shorten the production cycle, reduce production cost.
[embodiment]
Below the invention will be further described.
Rotating shaft is cleaned: clean up with gasoline or alcohol antirust oil and the impurity with the rotating shaft surface, place and make top gasoline or alcohol volatilization clean;
Rotating shaft preheats: baking oven is put in the rotating shaft that cleans up heated, according to the size of rotating shaft, volume size etc., oven temperature is set at 80-120 ℃, and is incubated more than 0.5 hour;
Mold pressing: molding die is put in the rotating shaft of rotor core and preheating, then the BMC material is put into the matched moulds pressurization of material chamber, carry out injection moulding, injection time can shorten 10～15 seconds of production cycle than the rotating shaft of not heating;
Clear up finished product: after mold pressing is finished, take out the unnecessary plastics in product cleaning surface, finished product.
Certain 25 gram left and right sides mold pressing 85 seconds former technology injection mo(u)lding time of axle of type materials, injection time foreshortened to 60 seconds after increase preheated operation;
Certain type materials 16 gram left and right sides mold pressing axle adopts this technology clamp time can be shortened to 40 seconds by 53 seconds, can reach the intensity and the insulating requirements of full solidification and product requirement equally, same equipment investment can be produced 160,000 mold pressing axles every year more, brings 4,480,000 yuan income nearly.
Claims (2)
