본 발명은 소형모터용 요크의 내주연에 프라스틱 마그네트를 부착하는 것에 관한 것으로서 특히 요크(Yoke)의 내부에 프라스틱 마그네트액을 사출하면서 자장을 인가하여 프라스틱 마그네트의 제작 및 부착을 한번의 공정으로 이루어질 수 있도록 한 것이 특징이다.The present invention relates to attaching a plastic magnet to the inner circumference of the yoke for a small motor, and in particular, by applying a magnetic field while injecting a plastic magnet fluid into the yoke, the manufacture and attachment of the plastic magnet can be achieved in one step. It is characterized by one.

종래에는 제3도에서와 같이 프라스틱 제품에 자장을 인가하여 별도의 사출로서 프라스틱 마그네트(22)를 제작한 후 환형으로 된 모터(Motor)용 요크(Yoke) 본체(21)의 내부에 부착하였다.Conventionally, as shown in FIG. 3, the magnetic field is applied to a plastic product to manufacture the plastic magnet 22 as a separate injection, and then attached to the inside of the yoke main body 21 for the motor.

이와같이 요크본체(21)의 내부에 프라스틱 마그네트(22)를 부착할때, 부착하기가 난이하므로 견고하지 못하여 프라스틱 마그네트(22)가 떨어지는 결점과 요크와 프라스틱 마그네트를 단품으로 사출하여 부착함에 따라, 2공정으로서 공수가 향상됨은 물론, 가격상승의 요인이 되는 문제점이 있었다.When the plastic magnet 22 is attached to the inside of the yoke body 21 as described above, it is difficult to attach the plastic magnet 22, and thus, the plastic magnet 22 falls off and the yoke and the plastic magnet are separately injected and attached. As a process, the airlift was improved and there was a problem of causing a price increase.

본 발명은 상기한 종래의 제결점 및 문제점을 감안하여 안출한 것으로 모터용 요크의 내부에 프라스틱 마그네트를 직접 사출하여 부착하는 과정에서 자장을 인가하여, 한번의 공정으로 요크내부에 프라스틱 마그네트를 제작 및 부착할 수 있도록 한 것이 그 목적이다.The present invention has been made in view of the above-mentioned conventional drawbacks and problems, by applying a magnetic field in the process of directly injecting and attaching a plastic magnet to the inside of the motor yoke, to produce and manufacture a plastic magnet in the yoke in one step The purpose is to be able to attach.

상기의 목적을 달성할 수 있는 본 발명을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings, the present invention that can achieve the above object is as follows.

제1도에 도시한 바와같이 내주연에 수개의 프라스틱 마그네트를 착자시킨 소형모터용 요크를 구성함에 있어서, 요크본체(1)의 내주연에 종방향으로 형성된 마그네트 착자용 요홈부(3)에 프라스틱 마그네트액(2´)를 압출시켜 마그네트(2)를 구성하되, 상기 요크본체(1)의 일측면에 밀폐형 금형(4)의 고정돌출부(5)를 삽입설치하여 고정시키고, 타측면에는 사출기(6)의 헤드부(7)를 삽입설치한후 겔상의 프라스틱 마그네트액(2´)를 압출시켜 상기 요크본체(1) 내주연에 형성된 요홈부(3)에 프라스틱 마그네트액(2´)을 충진시킨 다음, 요크본체(1)내의 자장코일(8)에 전류를 도통시켜 착자하여 마그네트(2)를 한번의 공정으로 제작 및 부착할 수 있도록 한 것이다.As shown in FIG. 1, in constructing a small motor yoke in which several plastic magnets are magnetized on an inner circumference, the magnet is recessed in a magnet magnetizing recess 3 formed in a longitudinal direction on an inner circumference of the yoke body 1. The magnet solution 2 'is extruded to form the magnet 2, and the fixed protrusion 5 of the hermetic mold 4 is inserted into one side of the yoke main body 1 and fixed thereto. After inserting the head portion 7 of 6), the plastic magnet liquid 2 'is extruded and the plastic magnet liquid 2' is filled in the groove portion 3 formed in the inner circumference of the yoke body 1 by inserting the head magnet 7 in the gel body. Then, the magnetic field is applied to the magnetic field coil 8 in the yoke body 1 to magnetize the magnet 2 so that the magnet 2 can be manufactured and attached in one step.

이와같이 된 본 발명은 내주연에 종방향으로 요홈부(3)가 형성된 요크본체(1)를 지지대에 고정시킨후 요크본체(1)의 일측에서 밀폐형 금형(4)의 고정돌출부(5)를 삽입설치하고, 타측에는 사출기(6)의 헤드부(7)를 요크본체(1)에 삽입설치하되, 상기 밀폐형 금형(4)의 고정돌출부(5) 일측단과 긴밀히 접촉되게 삽입설치한 후 사출기(6)에서 겔상의 프라스틱 마그네트액(2´)를 압출시켜 상기 요크본체(1)의 내주연에 형성된 요홈부(3)에 프라스틱 마그네트액(2´)을 충진시킨다음 요크본체내의 코어 내부에 있는 자장코일(8)에 전류를 도통시켜 착자하므로서 간편용이하게 요크본체(1) 내주연에 한번의 공정으로 마그네트(2)를 제작하면서 부착할 수 있는 것이다.According to the present invention, the yoke main body 1 in which the groove 3 is formed in the longitudinal direction at the inner circumference thereof is fixed to the support, and then the fixed protrusion 5 of the closed mold 4 is inserted at one side of the yoke main body 1. After inserting the head portion 7 of the injection molding machine 6 into the yoke body 1 on the other side, the injection molding machine 6 is inserted into the yoke body 1 so as to be in intimate contact with one end of the fixed protrusion 5 of the hermetic mold 4. Extrudes the gel-like plastic magnet solution 2 'to fill the groove portion 3 formed in the inner circumference of the yoke body 1 and fills the plastic magnet liquid 2' with the magnetic field inside the core in the yoke body. The magnets can be attached while making the magnets 2 in one step on the inner circumference of the yoke body 1 simply by magnetizing by conducting a current through the coils 8.

이상 설명한 바와같이 본 발명은 소형모터용 요크본체 내주연에 종방향으로 마그네트 착자용 요홈부를 형성하여 이 요홈부에 한번의 사출과정에서 마그네트 형상을 주입 제작과 동시에 자장코일의 전류를 도통시켜 착자하므로서 한번의 공정으로 제작과 부착을 겸할 수 있는 것으로서 작업이 간편용이하고 공수가 절감됨은 물론, 다량 생산할 수 있는 것이 특징이 있다.As described above, the present invention forms a magnet magnetizing recess in the longitudinal direction at the inner circumference of the yoke main body for the small motor, and magnetizes the magnet coil by conducting the magnet shape at the same time by injecting the magnet shape in one injection process. As it can combine production and attachment in one process, it is easy to work, saves labor, and can be produced in large quantities.
