본 고안은 모터 샤프트구멍에 부싱이 일체로 매설된 상태로 사출성형되어 지게한 진공소제기용 합성수지제 임펠러에 관한 것으로, 부싱을 임펠러와 동일한 합성수지 재질로 먼저 사출성형한 뒤 이를 임펠러 사출금형에 형성되어 있는 샤프트구멍 성형돌기에 끼워넣고 임펠러를 사출성형하므로서 임펠러의 모터 샤프트구멍에 부싱이 녹아붙어 일체 상태로 사출되어지도록한 것이다.The present invention relates to an impeller made of synthetic resin for vacuum cleaners, which is made to be injection-molded with a bushing integrally embedded in a motor shaft hole. It is inserted into the shaft hole forming protrusion, and the injection molding of the impeller is made so that the bushing is melted in the motor shaft hole of the impeller to be injected in an integrated state.
종래의 진공소제기용 합성수지제 임펠러는 모터샤프트구멍에 부싱을 끼우지않은 상태로 금형에서 그대로 사출성형 하였기 때문에 임펠러의 사출성형시 살아 두꺼운 부분에 내부응력이 집중되어 이로인한 자체변형이 심하게되었고 특히 모터 샤프트 구멍부분의 변형이 심하게되어 이에 삽입되는 모터 샤프트와 정확히 일치되지 않는 불량발생의 경우가 많았으며 이럴 경우 임펠러를 모터 샤프트에 억지조립시켜 제품을 생산 사용하게되면 임펠러의 회전시 편심으로 인한 소음과 진동이 심하게 발생되어 제품의 성능과 신뢰도를 떨어뜨리게되는 문제점이 있는 것이었다.Since the synthetic resin impeller for the vacuum cleaner is injection molded from the mold without inserting the bushing in the motor shaft hole, the internal stress is concentrated in the thick part during the injection molding of the impeller. In many cases, the deformation of the hole is so severe that it is not exactly matched with the motor shaft inserted into it.In this case, the impeller is forcibly assembled on the motor shaft to produce and use the product. This was badly generated, there was a problem that degrades the product performance and reliability.
본고안은 이와 같은 종래의 문제점을 해결한 것으로서, 진공소제기용 합성수지제 임펠러의 사출성형시 모터샤프트구멍에 동일재질의 합성수지제 부싱이 끼워져 일체화시킨 상태로 사출성형 하므로서 사출성형시 임펠러의 자체 변형을 방지하고 특히 모터 샤프트구멍 부분의 변형을 방지하여 주므로서 불량발생율을 낮추고 제품의 성능 및 신뢰도를 향상시킴에 그 목적이 있는 것이다.This paper solves such a conventional problem. When injection molding a synthetic resin impeller for a vacuum cleaner, the injection molding is made by inserting a synthetic resin bushing of the same material into the motor shaft hole. The purpose of the present invention is to reduce the occurrence rate of defects and to improve the performance and reliability of the product by preventing the deformation of the motor shaft hole, in particular.
본고안의 내용을 첨부도면에 의거 상세히 설명하면 다음과 같다.The contents of this draft will be described in detail with reference to the accompanying drawings.
즉, 중앙에 뚫린 공기흡입용구멍(2a)을 중심으로 다수개의 회전익(2b)들을 방사상으로 일정간격을 유지시켜 돌설되게한 전방판(2)과 중앙에 모터 샤프트구멍(3a)이 뚫린 수방판(3)을 각기 사출성형하여 이를 상호 접착시켜서 진공소제기용 합성수지제 임펠러(11)를 형성함에 있어서, 후방판(3)의 상출성형시 모터 샤프트구멍(3a)에 동일재질인 합성수지로 별도 사출성형시킨 부싱(4)이 매설되게 하되, 부싱(4)의 외면이 모터 샤프트구멍(3a)에 녹아붙게하여 후방판(3)과 일체로 사출성형함을 특징으로한 진공손제기용 합성수지제 임펠러인 것이다.That is, the front plate (2) to keep the plurality of rotary blades (2b) radially centered around the air suction hole (2a) in the center, and the water-proof plate with the motor shaft hole (3a) in the center In the injection molding (3) and bonding them to each other to form a synthetic resin impeller 11 for vacuum cleaner, the injection molding of the back plate 3 is separately injection-molded with synthetic resin having the same material in the motor shaft hole 3a. The bushings 4 are embedded, but the outer surface of the bushings 4 are melted in the motor shaft hole 3a so that the injection molding is integrated with the rear plate 3, and the synthetic resin impeller for vacuum cleaner will be.

본고안의 성형과정을 첨부도면 제2도에 의거 상세히 설명하면, 먼저 a도에서 보는 바와 같이 임펠러(1)의 구성부품인 후방판(3)을 사출성형하기위한 금형의 고전측형판(6)과 가동측형판(7) 사이를 열고 코아핀(9)의 상단에 돌설되어있는 모터 샤프트구멍 성형용돌기(9a)에다 별도로 사출성형시킨 합성수지제 부싱(4)을 끼운다음 고정측형판(6)과 가동측형판(7) 사이를 다시 닫아준 후 스프루부시를 통해 합성수지용탕을 금형내부로 사출시켜주면, b도 에서와 같이 부싱(4)이 매설되어진 상태로 후방판(3)이 성형고화되는 것이다.The molding process of the present invention will be described in detail with reference to FIG. 2 of the accompanying drawings. First, as shown in FIG. A, the high side plate 6 of the mold for injection molding the back plate 3 which is a component of the impeller 1 and Open between the movable side plate (7) and insert the bushing (4) made by injection molding separately into the motor shaft hole forming protrusion (9a) protruding from the top of the core pin (9), and then the fixed side plate (6) and After closing the movable side plate 7 again and injecting the molten resin into the mold through the sprue bushing, the back plate 3 is molded and solidified with the bushing 4 embedded therein as shown in FIG. will be.
이때 고화되기 전인 용탕의 높은 온도와 이미 고화된 부싱(4)의 낮은 온도와의 차이에 따른 열역학제로법칙에 의해 부싱(4)의 외면이 약간 녹게되면서 점차 고화성형되는 후방판(3)의 모터샤프트구멍(3a)에 부싱(4)이 녹아붙게되고 이 과정에서 후방판(3)에 작용되는 내부응력을 부싱(4)이 고르게 분산처리 하게됨에따라 후방판(3)의 변현을 방지하게 됨은 물론 부싱(4)에 의해 모터샤프트구멍(3a)이 일정한 형태로 정확히 성형되어지는 것이다.At this time, the motor of the back plate 3 gradually solidifies as the outer surface of the bushing 4 is slightly melted by the thermodynamic zero law according to the difference between the high temperature of the molten metal before solidifying and the low temperature of the bushing 4 already solidified. Since the bushing 4 is melted in the shaft hole 3a and the bushing 4 evenly disperses the internal stress acting on the rear plate 3 in this process, it is possible to prevent the deformation of the rear plate 3. Of course, by the bushing 4, the motor shaft hole 3a is precisely molded into a certain form.
본고안은 상술한 바와 같이 진공소제기용 합성수지제 임펠러(1)를 사출성형 할 때 후방판(3)의 모터샤프트구멍(3a)에 임펠러(1)와 동일한 재질로 되는 합성수지제 부싱(4)을 별도 사출성형하여 일체화되도록 매설하여 주는 것이어서 임펠러(1)를 구성하는 후방판(3)의 사출성형시 내부응력에 의한 자체변형 및 모터샤프트구멍(3a)의 변형을 방지하게 되어 불량발생률을 대폭 감소시키는 동시에 모터샤프트(11a)와 임펠러(1)간의 조립상태가 편심되지않고 정확하게 일치되어짐에 따라 임펠러(1)의 회전사용시 편심으로인한 소음과 진동을 방지하게되어 제품의 성능이나 신뢰도를 향상시켜주게되는 것이어서 경제적이나 실용적으로 매우 큰 효과를 제공하여 주는 것이다.As described above, the present invention uses a synthetic resin bushing 4 made of the same material as the impeller 1 in the motor shaft hole 3a of the rear plate 3 when injection molding the synthetic resin impeller 1 for vacuum cleaner. Since it is embedded to be integrated by injection molding separately, it prevents self deformation and deformation of the motor shaft hole 3a due to internal stress during injection molding of the back plate 3 constituting the impeller 1, thereby greatly reducing the failure rate. At the same time, as the assembly state between the motor shaft 11a and the impeller 1 is not eccentric and is exactly matched, it prevents noise and vibration caused by eccentricity when rotating the impeller 1, thereby improving product performance or reliability. It is very economically and practically very effective.
