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
The present invention relates to motor parts production technical field, be specifically related to the moulding process of a kind of BMC moulding compound compacting motor rear end lid.
Background technology
In the prior art, the rear end cap of motor adopts the metal material such as iron, aluminium to make usually, there is easy conduction, heaviness, be inconvenient to problems such as installing in the motor rear end lid that this metal material is made, meanwhile, adopts metal material to make and also runs counter to the sustainable development idea of current energy-conserving and environment-protective.
BMC(Bulkmoldingcompounds) material and BMC, is domesticly often called unsaturated polyester (UP) BMC.Its primary raw material is by GF (short glass fiber), UP (unsaturated-resin), MD (filler) and the various additive material bulk prepreg through fully mixing, there is molding cycle short, the various features such as fire-retardant, cost is low, and product heat resistance, insulating properties are good.How by rational technical process, BMC being made motor rear end lid is this area technical problem urgently to be resolved hurrily.
Summary of the invention
For solving the technical problem existed in prior art, the invention provides the moulding process that Process Design rational BMC moulding compound compacting motor rear end lid is provided.
Technique effect of the present invention is achieved through the following technical solutions:
A moulding process for BMC moulding compound compacting motor rear end lid, specifically comprises the following steps:
Step one: setting mold temperature, setting cylinder pressure;
Step 2: add BMC moulding compound in mould;
Step 3: compacting tool set, and after breathing freely several times, pressurize is shut down;
Step 4: molding;
Step 5: goods are put into cold mould cooling forming.
Further, described mold temperature is set to 140-160 DEG C.
Further, described cylinder pressure is set to 12-15MPa.
Further, before carrying out step 2, refuse in mould is cleared up.
Further, described mould is divided into mold and bed die, and described BMC moulding compound puts into described mold and described bed die respectively, and described BMC moulding compound is 300-400g.
Further, described ventilative number of times is 2-3 time.
Further, the described dwell time is 5-7 minute.
Further, described goods cool times in described cold mould is 2-5 minute.
Further, after molding, described products appearance checked, ensure described goods flawless, sticking to mould, pollution, lack material phenomenon.
The invention has the beneficial effects as follows:
The moulding process of BMC moulding compound disclosed in this invention compacting motor rear end lid, technological design is reasonable, and motor rear end lid is compressing by BMC moulding compound, makes motor rear end lid have the plurality of advantages such as good insulating, easy for installation, economize energy.
Detailed description of the invention
The specific embodiment of the invention is introduced in detail below by different embodiment.
Embodiment one:
A moulding process for BMC moulding compound compacting motor rear end lid, specifically comprises the following steps:
1, operative employee checks hydraulic cylinder surface, checks and represents temperature, hardening time etc., whether parameter met process stipulation.Setting mold temperature, concrete, patrix temperature is set to 140 degree, and counterdie temperature is set to 140 degree, and cylinder pressure is set to 12MPa.
2, check material BMC moulding compound outer packing mark, confirm errorless.
3, clear up refuse in mould, in mould, add BMC moulding compound, feeding quantity is 300g, separately uses with color material gloves, prevents foreign material and heterochromaticly to enter in material.
4, confirm the whether realistic materials of BMC moulding compound feeding quantity, divided by BMC moulding compound two pieces to expect the die cavity that group puts as mold and bed die, and mold and bed die are suppressed rapidly, ventilative twice time, shut down to pressurize.
5, pressurize terminates rear molding, takes out goods.The pressurize time is from start to end 5 minutes.
6, hand inspection, visually observes, and checks products appearance, the phenomenon such as flawless, sticking to mould, pollution, scarce material.
7, cooling 2 minutes on cold mould goods being put into regulation, in order to avoid distortion.
8, cooled goods are put into Turnover Box and proceed to next procedure.
