Background technology
At present, micro machine commutator of the prior art is mainly pressed solidly by 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 by the rotating shaft of mould plastic compression in the commutator plastics, by analysis, commutator segment and the rotating shaft of adopting the mould plastic compression will form the micro machine commutator at present exist unreasonable part by the processing method that the fiberglass plastic bonding presses solidly together: the existing plastic compression processed mould structure that is used for is mainly by the gate plate plate, cavity plate, base plate and lead are formed (as shown in Figure 6), adopt this mould that commutator segment and rotating shaft are pressed solidly when forming the micro machine commutator by 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, micro machine commutator behind the plastic pressure forming to be taken out, could take out the micro machine commutator from the die cavity hole tail end strike rotating shaft of cavity plate after only opening base plate, this method that micro machine commutator behind the plastic pressure forming is taken out from mould, can be easy to make bonding press solidly together rotating shaft and fiberglass plastic between produce vibration, form waste product thereby cause the rotating shaft of a lot of micro machine commutators and fiberglass plastic 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 purpose of this utility model is: provide the plastic compression processing mold of a kind of yield rate height and simple in structure, easy to operate micro machine commutator, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: the plastic compression processing mold of a kind of micro machine commutator of the present utility model is, comprise gate plate, cavity plate, base plate, lead and attachment screw, cavity plate is connected on the base plate by attachment screw, gate plate is connected on the cavity plate by lead, on cavity plate, be provided with the installing hole that the Hough piece is installed, one 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 utility model 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 reposefully from the bottle opener notch with molding instrument bottle opener, so just can easily the micro machine commutator be taken out from mould, and finish the process of a plastic compression micro machine commutator.Wholely go out in the mold process of the present utility model, the micro machine commutator is not subjected to 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 utility model 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 utility model compared with prior art, the utility model not only has yield rate height, simple in structure, easy to operate advantage, but also have the cost of saving, raise labour productivity greatly, advantages such as product quality height and steady quality.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: the plastic compression processing mold of micro machine commutator of the present utility model comprises gate plate 4, cavity plate 5, base plate 6, lead 7 and attachment screw 8, cavity plate 5 is connected on the base plate 6 by attachment screw 8, gate plate 4 is connected on the cavity plate 5 by lead 7, on cavity plate 5, make an installing hole that Hough piece 9 is installed, and a secondary Hough piece 9(is installed as shown in Figure 1 in this installing hole), this pair Hough piece 9 is made up of the metal derby of two semi-cylindrical form, and the die cavity hole 10(that makes a rotating shaft 2 that is used to install the micro machine commutator at the center position of two Hough pieces 9 that combine as shown in Figure 1); During making, for convenient in taking out Hough piece 9, big, the little tapered hole in lower end on the installing hole of cavity plate 5 can being made as, and the external cylindrical surface that will be installed in the Hough piece 9 that the metal derby by two semi-cylindrical form in this installing hole forms also is made as, and the upper end is big, the little conical surface in lower end, and makes the tapering α of this conical surface and the tapering identical (as shown in Figure 2) of installing hole; The tapering α of the external cylindrical surface conical surface that will be made up of two Hough pieces 9 is made as 5 °～8 °; Separate for convenience in two Hough pieces 9 that will combine, can produce at the faying face place of two Hough pieces 9 two symmetrical distributions bottle opener notch 11 (as shown in Figure 3).
