Description
Technical field
The present invention relates to a kind of plastic compression processing method and plastic compression processing mold of micro machine commutator, belong to micro machine commutator processing technique field.
Background technology
At present; Micro machine commutator of the prior art is mainly pressed solidly through the fiberglass plastic bonding with rotating shaft by commutator segment is in the same place; Thereby often in the production of existing micro machine commutator occur separating with fiberglass plastic to produce looseningly causing commutator to scrap phenomenon by the gross through the rotating shaft of mould plastic compression in the commutator plastics; Through analyzing; Commutator segment and the rotating shaft of adopting the mould plastic compression will form the micro machine commutator at present exist unreasonable part through the processing method that the fiberglass plastic bonding presses solidly together: the existing plastic compression processed mould structure that is used for is mainly formed (as shown in Figure 6) by gate plate plate, cavity plate, base plate and lead; Adopt this mould that commutator segment and rotating shaft are pressed solidly when forming the micro machine commutator through the fiberglass plastic bonding together; The rotating shaft end of the micro machine commutator behind its plastic pressure forming is also in the cavity plate of mould; To the micro machine commutator behind the plastic pressure forming be taken out, only open behind the base plate and to hit rotating shaft from the die cavity hole tail end of cavity plate could take out the micro machine commutator, this method that micro machine commutator behind the plastic pressure forming is taken out from mould; Can be easy to make bonding to press solidly between rotating shaft and the fiberglass plastic together and produce vibration, form waste product thereby cause rotating shaft and the fiberglass plastic of a lot of micro machine commutators to peel off.Therefore, the plastic compression processing method of existing micro machine commutator and plastic compression processing mold structure still are not ideal enough.
Summary of the invention
The objective of the invention is to: the plastic compression processing method and the plastic compression processing mold of a kind of yield rate micro machine commutator high and simple in structure, easy to operate are provided, to overcome the deficiency of prior art.
The present invention is achieved in that the plastic compression processing method of a kind of micro machine commutator of the present invention does; Comprising that the commutator segment that adopts existing mould plastic compression method for processing will form the micro machine commutator bonds to press solidly through fiberglass plastic with rotating shaft is in the same place; Carry out plastic compression at the employing mould and add man-hour; Die cavity hole in the cavity plate in the existing mold that will be made up of gate plate, cavity plate, base plate, lead and attachment screw enlarges, and a secondary Hough piece is installed in the die cavity hole after this enlarges, and produces the die cavity hole at the center position of this pair Hough piece that combines; By traditional mode cavity plate is installed on the base plate through attachment screw then; The die cavity hole is put in the rotating shaft of forming the micro machine commutator, the commutator segment of forming the micro machine commutator is enclosed within the upper part of rotating shaft, gate plate is covered after on the cavity plate through lead; Press traditional approach again and press the notes fiberglass plastic; Commutator segment is pressed solidly with the rotating shaft bonding be in the same place, at this moment gate plate and cavity plate separated, this pair Hough piece is taken out from cavity plate together with commutator segment and rotating shaft that bonding presses solidly together; Should separate by pair Hough piece then, can take out like this and obtain pressing solidly the micro machine commutator finished product of together forming through the fiberglass plastic bonding by commutator segment and rotating shaft.
When commutator segment is enclosed within the upper part of rotating shaft, earlier processing is flattened in the upper part of rotating shaft above-mentioned, make the upper part of rotating shaft be formed with the flattening plane of two symmetries.
The plastic compression processing mold that is used for a kind of micro machine commutator of the inventive method does; Comprise gate plate, cavity plate, base plate, lead and attachment screw; Cavity plate is connected on the base plate through attachment screw; Gate plate is connected on the cavity plate through lead, on cavity plate, is provided with the installing hole that the Hough piece is installed, and a secondary Hough piece is installed in this installing hole; This pair Hough piece is made up of the metal derby of two semi-cylindrical form, and is provided with the die cavity hole of the rotating shaft that is used to install the micro machine commutator at the center position of two Hough pieces that combine.
The installing hole of above-mentioned cavity plate is the tapered hole that the upper end is big, the lower end is little, and the external cylindrical surface of being made up of two Hough pieces that is installed in this installing hole also is the conical surface that the upper end is big, the lower end is little, and the tapering of this conical surface is identical with the tapering of installing hole.
The tapering of the above-mentioned external cylindrical surface conical surface of being made up of two Hough pieces is 5 °～8 °.
Faying face place at above-mentioned two Hough pieces is provided with the bottle opener notch.
Owing to adopted technique scheme; The present invention adopts the micro machine commutator behind the plastic pressure forming is stayed in the Hough piece; Then the time with the depanning of micro machine commutator; Open the Hough piece that combines with molding instrument bottle opener reposefully from the bottle opener notch, so just can easily the micro machine commutator be taken out from mould, and accomplish the process of a plastic compression micro machine commutator.Wholely go out in the mold process of the present invention, the micro machine commutator does not receive any impulsive force, can not produce distortion, and its rotating shaft is combining with fiberglass plastic with reinforcing, thereby produces a desired effect.Prove that through production application adopt the present invention to carry out the plastic compression processing of micro machine commutator, its qualification rate reaches more than 95%, about 60% the qualification rate that has substantially exceeded that present employing prior art only can reach.Therefore, the present invention compared with prior art, the present invention not only has yield rate height, simple in structure, easy to operate advantage, but also have the cost of saving, raise labour productivity greatly, product quality is high and advantage such as steady quality.
