Description

사출 수전금구 제조방법 {a manufacturing method for injection faucet}Manufacturing method for injection faucet {a manufacturing method for injection faucet}

본 발명은 수전금구본체와 물공급부가 금형에 의한 사출성형으로 각각 제작된 후 결합수단을 통하여 일체로 연결되고, 상기 수전금구본체와 물공급부의 외측에 이중사출에 의해 외부케이스를 일체로 성형하며, 상기 수전금구본체와 물공급부를 제작할 때 내부에 서로 연결되는 공간의 형성을 위하여 적어도 하나의 코어가 사용되며, 상기 수전금구본체와 물공급부에 형성되는 코어배출공을 마개에 의해 덮도록 하는 사출 수전금구 제조방법에 관한 것이다.According to the present invention, the faucet bracket body and the water supply part are each manufactured by injection molding by a mold, and then integrally connected through a coupling means, and the outer case is integrally formed by double injection on the outside of the faucet fixture body and the water supply part. At least one core is used to form a space connected to each other when the faucet fixture body and the water supply part are manufactured, and the injection hole to cover the core discharge hole formed in the faucet fixture body and the water supply part by a stopper. It relates to a method for manufacturing a power receiving bracket.

일반적으로 수도꼭지는 유출구의 내부가 언더컷 상태이기 때문에 종래의 일반적인 사출성형방법으로는 성형이 불가능하다. In general, since the faucet has an undercut inside of the outlet, it is impossible to mold by a conventional injection molding method.

이로 인해 주로 금속제로 주조하는 제조방법으로 제조되고 있다.For this reason, it is manufactured by the manufacturing method mainly cast into metal.

그리고, 수도계량기 및 수도꼭지 등의 수도관련 물품은 사람들이 매일 음용하는 수돗물을 공급하기 위한 생활용품인 바 그 관련 용품들이 위생적으로 관리되어야 하고 또한 부식에 강해야 하는 것이 필수 요구조건이므로 그동안 주로 내식성이 강한 구리(Cu)와 아연(Zn)을 주성분으로 하는 합금인 황동제이거나 또는 구리(Cu)와 주석(Sn)을 주성분으로 하는 합금인 청동제를 주원료로 사용하는 주조 작업을 통하여 수도계량기 중자 등을 주조하여 사용하여 왔었다.In addition, since water-related items such as water meters and faucets are daily necessities for supplying tap water that people drink daily, the related items must be hygienically managed and must be resistant to corrosion. Casting water meter cores through casting operations using brass, which is an alloy mainly composed of copper (Cu) and zinc (Zn), or bronze, which is an alloy mainly composed of copper (Cu) and tin (Sn) Had been using.

즉, 종래의 수도 관련용품들의 주물 제조공정을 살펴보면 필요로 하는 형상으로서 금형을 제작하여 구리(Cu)와 아연(Zn)을 적절히 섞어 융합시킨 황동 주물에 의해 황동제의 수도계량기 중자를 성형하게 되는데 이렇게 성형되는 수도계량기는 그 표면이 대단히 거친 상태이므로 버핑(buffing)에 의해서 표면 연마를 한 후 도금이나 최종 표면 처리를 하여 부식에 강한 수도계량기 중자를 만드는 공정이 사용되어 왔다.In other words, if you look at the casting manufacturing process of the conventional water-related products, it is necessary to make a mold as a shape that is required to form the middle of the water meter made of brass by brass casting, which is a suitable mixture of copper (Cu) and zinc (Zn). Since the water meter thus formed has a very rough surface, a process of making a water meter core that is resistant to corrosion by plating and final surface treatment after surface polishing by buffing has been used.

그러나, 상기와 같은 수전제품은, 수도꼭지의 제작을 위하여 중자를 반드시 필요로 하여 원가가 상승되며, 탈왁스의 공정후 쇼팅 등의 공정을 필요로 하여 공정이 복잡하고, 양산에 의한 원가절감이 힘들게 되는 단점이 있는 것이다.However, the faucet product as described above requires a middle element for the manufacture of the faucet, the cost is increased, and the process is complicated, such as short-waxing after dewaxing process, the process is complicated, and cost reduction by mass production is difficult There is a disadvantage.

계속하여, 상기 수전금구본체(110)와 물공급부(150)는 금형을 통한 사출성형으로 제작할 때 내부에 물의 유동을 위하여 서로 연결되는 기하학적 형상의 공간 형성을 위하여 적어도 하나의 코어가 사용되며, 상기 수전금구본체와 물공급부에 각각 형성되는 코어배출공(710)을 통하여 배출토록 된다.Subsequently, the faucet fixture body 110 and the water supply unit 150 are at least one core is used to form a geometric space connected to each other for the flow of water when the injection molding through the mold is formed, It is discharged through the core discharge hole 710 respectively formed in the faucet bracket body and the water supply unit.

그리고, 상기 코어의 배출에 의해 형성되는 코어배출공(710)은 이에 대응토록 별도의 공정에 의해 제작되는 마개(700)에 의해 덮도록 한다.In addition, the core discharge hole 710 formed by the discharge of the core is to be covered by a stopper 700 produced by a separate process to correspond thereto.

즉, 본 발명은 수전금구를 수전금구본체와 물공급부를 분리하여 사출성형에 의해 제작하면서 각각의 수전금구본체와 물공급부를 복수의 코어를 통해 제작한 후 마개를 통해 조립하여 다양한 외형을 갖는 수전금구의 제작이 가능토록 되는 것이다.That is, in the present invention, the faucet bracket is separated from the faucet bracket main body and the water supply part by injection molding, and the faucet bracket body and the water supply part are manufactured through a plurality of cores, and then assembled through a stopper. It is possible to manufacture the bracket.
