Embodiment 1

[0024] A molding process for BMC molding compound to press the motor rear end cover, specifically comprising the following steps:

[0025] 1. The operator checks the surface of the hydraulic cylinder to check whether the parameters such as temperature and curing time meet the process regulations. Set the mold temperature, specifically, set the temperature of the upper mold to 140 degrees, the temperature of the lower mold to 140 degrees, and the pressure of the hydraulic cylinder to 12MPa.

[0026] 2. Check the logo on the outer packaging of the material BMC molding compound, and confirm that it is correct.

[0027] 3. Clean up the waste in the mold, add BMC molding compound to the mold, the amount of material added is 300g, and use the color material gloves separately to prevent sundries and different colors from entering the material.

[0028] 4. Confirm whether the amount of BMC molding compound is in line with the actual material used. Divide the BMC molding compound into...

Embodiment 2

[0034] A molding process for BMC molding compound to press the motor rear end cover, specifically comprising the following steps:

[0035] 1. The operator checks the surface of the hydraulic cylinder to check whether the parameters such as temperature and curing time meet the process regulations. Set the mold temperature, specifically, set the temperature of the upper mold to 160 degrees, the temperature of the lower mold to 160 degrees, and the pressure of the hydraulic cylinder to 15MPa.

[0036] 2. Check the logo on the outer packaging of the material BMC molding compound, and confirm that it is correct.

[0037] 3. Clean up the waste in the mold, add BMC molding compound to the mold, the feeding amount is 400g, and use the color material gloves separately to prevent sundries and different colors from entering the material.

[0038] 4. Confirm whether the amount of BMC molding compound is in line with the actual material used. Divide the BMC molding compound into two piece...

Abstract

The invention relates to a molding technology for a motor rear end cover through BMC pressing. The technology specifically comprises following steps that firstly, the mold temperature and the hydraulic cylinder pressure are set; secondly, BMC are added into a mold; thirdly, the mold is pressed, ventilation is carried out multiple times, and pressure maintaining and closing down are carried out; fourthly, drawing is carried out; and fifthly, a product is put into a cold mold for cold molding. The molding technology for the motor rear end cover through BMC pressing is reasonable in technology design, the motor rear end cover is molded through BMC pressing, and the motor rear end cover has the beneficial effects of being good in insulation and convenient to mount, saving energy and the like.

Description

technical field [0001] The invention relates to the technical field of motor component production, in particular to a molding process for pressing a motor rear end cover with a BMC molding compound. Background technique [0002] In the prior art, the rear end cover of the motor is usually made of metal materials such as iron and aluminum. The motor rear end cover made of this metal material has problems such as easy conduction, bulkiness, and inconvenient installation. At the same time, the use of metal materials The production is also contrary to the current concept of sustainable development of energy saving and environmental protection. [0003] BMC (Bulkmoldingcompounds) material is bulk molding compound, which is often called unsaturated polyester bulk molding compound in China. Its main raw materials are GF (chopped glass fiber), UP (unsaturated resin), MD (filler) and various additives. The dough-like prepreg is fully mixed. It has short molding cycle, flame retardan...
