Description

파팅 라인이 없는 니플Nipple without parting line
본 발명은 파팅 라인이 없는 니플에 관한 것으로, 더욱 상세하게는 니플의 외측면에 버와 같은 파팅 라인이 형성되지 않으며, 성형된 니플을 니플 슬리브로부터 용이하게 취출할 수 있는 파팅 라인이 없는 니플에 관한 것이다.The present invention relates to a nipple without a parting line, and more particularly, to a nipple without a parting line, in which no parting line such as a burr is formed on an outer surface of the nipple, and a molded nipple can be easily taken out from the nipple sleeve. It is about.
일반적으로 금형을 이용한 사출가공 시 성형된 제품에 버(Burr)가 형성된다. 즉, 버는 형합되는 두 금형 사이에 형성되는 캐비티에 충전제가 채워져 소정의 형상을 갖는 제품이 성형되었을 때 두 금형이 맞닿는 경계(parting line)를 따라 형성되는 것으로, 이러한 버는 제품이 다른 제품과 조립될 때 악영향을 주게 된다.Generally, a burr is formed in a molded product during injection processing using a mold. That is, the burrs are formed along a parting line where the two molds come into contact with each other when a product having a predetermined shape is formed by filling a cavity formed between two molds to be joined. It will be adversely affected.
예를 들어, 사출 성형된 제품에 니플이 형성되고, 상기 니플의 파팅 라인을 따라 버가 형성되는 경우 니플이 관로와 연결될 때 버에 의해 기밀하게 연결되지 않고 틈새를 형성하여 누수가 발생하게 된다. 또한, 관로가 고무관과 같은 경우에는 관로를 니플에 조립하는 중에 관로가 찢어지게 되는 문제가 발생하게 된다.For example, when a nipple is formed on an injection-molded product and a burr is formed along the parting line of the nipple, when the nipple is connected to the pipeline, a leak is generated by forming a gap without being hermetically connected by the burr. In addition, when the pipeline is a rubber tube, a problem occurs that the pipeline is torn while assembling the pipeline to the nipple.
따라서, 종래에는 사출 성형된 니플에 형성된 버를 제거하기 위해 니플과 동일한 형상을 갖는 프레스 금형에 안치시킨 후 절단 금형의 가압에 의해 버를 제거하거나 또는 수작업에 의해 작업자가 커터를 사용하여 니플에 형성된 버를 제거하게 된다.Therefore, in order to remove the burrs formed in the injection-molded nipple conventionally placed in a press mold having the same shape as the nipple and then removed the burrs by pressurization of the cutting die or by a manual operation by the operator using a cutter to form the nipples This will remove the burr.
그러나, 상기와 같은 프레스 가공 또는 수작업에 의한 버의 제거는 별도의 가공공정이 추가됨으로써, 제품의 생산성을 저하시킬 뿐만 아니라 버를 제거하는 중에 니플이 파손될 우려가 있어 실수율이 감소하게 된다.However, the removal of the burr by pressing or manual work as described above is not only to reduce the productivity of the product by adding a separate processing process, the nipple may be damaged while removing the burr, thereby reducing the error rate.
이에 따라, 본 출원인은 특허등록 제1298854호의 "니플을 갖는 성형물용 성형기"를 출원하여 등록받은 바 있다. 이러한 본 출원인에 의한 "니플을 갖는 성형물용 성형기"는 성형물을 성형하는 메인캐비티가 내부에 마련되어 상기 메인 캐비티에 충전되는 레진에 의해 내부에서 상기 성형물을 성형하고, 상기 성형물의 상기 니플을 성형하기 위한 니플공을 갖는 금형 본체 및 상기 금형 본체의 니플공에 결합되어 상기 금형본체와 일체를 이루고, 상기 니플공을 차폐한 상태로 상기 니플이 성형되는 니플 캐비티를 상기 니플공에 제공하며, 상기 니플의 걸림턱이 성형되는 니플 캐비티의 일단부를 개폐하여 상기 니플을 성형하거나 상기 니플의 취출을 위한 탄성변형 공간을 제공하는 니플 금형으로 구성된다.Accordingly, the present applicant has applied for and registered a "molding machine for moldings having a nipple" of Patent Registration No. 1298854. Such a "former for moldings with nipples" according to the present applicant is for forming the moldings therein by a resin filled in the main cavity provided with a main cavity for molding the moldings, and for forming the nipples of the moldings. The nipple is coupled to the mold main body having the nipple hole and the nipple hole of the mold body, the nipple is formed in the state of the mold body, and the nipple is formed in the state in which the nipple is shielded. It is composed of a nipple mold that opens and closes one end of the nipple cavity in which the locking jaw is formed, thereby forming the nipple or providing an elastic deformation space for taking out the nipple.
특히, 상기 니플 금형은 상기 금형 본체의 니플공에 삽입상태로 결합되고, 양단부가 개방된 관체형으로 형성되며, 상기 니플의 외형에 대응하는 내부면을 갖는 니플 슬리브와, 상기 니플 슬리브를 상기 금형 본체에 일체적으로 고정하는 패스너 및 상기 금형본체의 외측에서 상기 니플 슬리브의 일단부에 착탈가능하게 결합되면서 상기 걸림턱의 성형을 위한 상기 니플 캐비티의 일단부가 위치하는 상기 니플 슬리브의 일단부를 개폐하는 핀형태의 코어로 구성되어 니플의 파팅 라인에 버나 단차와 같은 부분이 발생하지 않게 된다.In particular, the nipple mold is coupled to the nipple hole of the mold body, the nipple sleeve is formed in a tubular shape with both ends open, the nipple sleeve having an inner surface corresponding to the outer shape of the nipple, and the nipple sleeve to the mold A fastener integrally fixed to the main body and detachably coupled to one end of the nipple sleeve from the outside of the mold body to open and close one end of the nipple sleeve at which one end of the nipple cavity for forming the locking jaw is located. It consists of a pin-shaped core so that parts such as burrs and steps are not generated in the parting line of the nipple.
그러나, 상기와 같은 성형기에 의해 니플이 성형되는 경우 니플이 니플 슬리브로부터 취출되는 과정에서 니플의 선단이 파손되는 문제가 있다. 이를 도 1에 의거하여 설명한다.However, when the nipple is molded by the molding machine as described above, there is a problem in that the tip of the nipple is broken while the nipple is taken out from the nipple sleeve. This will be described based on FIG. 1.
도 1은 니플 슬리브에서 성형된 니플의 취출을 나타낸 단면도이다. 도면을 참조하여 설명하면, 니플 슬리브(10)와 코어(20) 사이에 형성된 캐비티에 수지가 채워져 니플(P)이 형성된다. 이때, 니플 슬리브(10)의 내경에는 니플(P)의 선단 외주면에 형성된 걸림턱(Pa)에 부합하는 형상의 캐비티가 형성되어 성형된 니플(P)에 관로가 조립될 때 걸림턱(Pa)에 의해 밀착되는 구조를 갖는다.1 is a cross-sectional view showing the extraction of a nipple molded from a nipple sleeve. Referring to the drawings, the cavity formed between the nipple sleeve 10 and the core 20 is filled with resin to form the nipple P. At this time, the inner diameter of the nipple sleeve 10 is formed with a cavity having a shape corresponding to the locking jaw (Pa) formed on the outer peripheral surface of the tip of the nipple (P), the locking jaw (Pa) when the pipe is assembled to the molded nipple (P) It has a structure that is in close contact with.
이렇게, 걸림턱(Pa)이 형성된 니플(P)이 성형되면 니플(P)을 포함한 성형물을 취출하기 위해 니플 슬리브(10)가 성형물을 향해 이동하게 되고, 이때 코어(20)가 니플(P)에서 이탈하게 된다.As such, when the nipple P having the locking jaw Pa is molded, the nipple sleeve 10 is moved toward the molding to take out the molding including the nipple P, and the core 20 is the nipple P. Will leave.
이와 같이 코어(20)가 니플(P)에서 이탈한 후에는 니플(P)의 선단이 니플 슬리브(10)로부터 이탈되는데, 이때 니플(P)의 선단에 형성된 걸림턱(Pa)에 의해 니플의 선단이 탄성변형되어 원래 성형된 니플(P)의 내경 지름보다 좁게 오므라들면서 니플 슬리브(10)에서 이탈된다.As described above, after the core 20 is separated from the nipple P, the tip of the nipple P is separated from the nipple sleeve 10. At this time, the nipple P of the nipple is formed by the engaging jaw Pa formed at the tip of the nipple P. The tip is elastically deformed and pulled away from the nipple sleeve 10 while being narrower than the inner diameter of the originally formed nipple P.
그러나, 상기와 같이 니플 슬리브(10)에서 니플(P)이 이탈되는 과정에서 니플(P)의 선단이 탄성변형되기는 하지만 경우에 따라서는 니플(P)의 선단이 탄성변형되지 않고 니플(P)의 선단이 깨지면서 크랙을 발생하게 된다.However, although the tip of the nipple P is elastically deformed in the process of the nipple P is separated from the nipple sleeve 10 as described above, in some cases the tip of the nipple P is not elastically deformed and the nipple P is not. The tip of the crack is broken, causing a crack.
이와 같이 니플(P)의 선단에 크랙이 발생하게 되면 크랙에 의해 기밀성이 감소되거나 관로를 니플에 조립하는 과정에서 강성이 약해진 니플(P)이 파손되어 결국 니플(P)과 관로의 결속력이 약해져 관로와 니플(P)이 의도하지 않게 분리되는 문제가 있다.If cracks occur at the tip of the nipple (P), the airtightness is reduced by the crack, or the nipple (P), which is weak in the process of assembling the pipe to the nipple, is damaged, resulting in weakening of the binding force between the nipple (P) and the pipe. There is a problem that the pipe and the nipple P are inadvertently separated.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제 1 실시예First embodiment
도 2는 본 발명에 따른 파팅 라인이 없는 니플의 제1실시예를 나타낸 단면 사시도이고, 도 3은 본 발명의 제1실시예에 따른 파팅 라인이 없는 니플을 나타낸 단면도이다.2 is a sectional perspective view showing a first embodiment of a nipple without a parting line according to the present invention, and FIG. 3 is a sectional view showing a nipple without a parting line according to the first embodiment of the present invention.
도면을 참조하여 설명하면, 본 발명에 따른 파팅 라인이 없는 니플(100)은 내부에 유체가 흐를 수 있게 유로가 형성된 몸체(110), 몸체(110)의 선단 외측면에 형성되는 걸림턱(120)으로 구성된다.Referring to the drawings, the nipple 100 without the parting line according to the present invention is a body 110, a flow path is formed so that the fluid flow therein, the locking step 120 formed on the outer surface of the front end of the body 110 It is composed of
특히, 본 발명에 따른 니플(100)은 몸체(110)의 선단 내측면에 두께가 얇아지는 탄성변형구간(130)을 형성하여 니플 슬리브에서 니플(100)이 취출될 때 몸체(110)의 선단이 오므라지는 탄성변형을 용이하게 할 수 있도록 함으로써 니플(100)이 파손되는 것을 방지할 수 있다.In particular, the nipple 100 according to the present invention forms an elastic deformation section 130 that becomes thinner on the inner side of the front end of the body 110, so that the tip of the body 110 when the nipple 100 is taken out from the nipple sleeve It is possible to prevent the nipple 100 from being damaged by making it possible to facilitate the elastic deformation.
부연하자면, 몸체(110)는 니플 슬리브와 코어 사이에 형성된 캐피티에 수지가 채워져 성형되는 것으로 내부에 유체가 흐를 수 있게 유로가 형성된다. 이렇게 몸체(110)의 내부에 형성되는 유로는 니플 슬리브에 삽입된 코어에 의해 형성되는 것으로 니플 슬리브로부터 코어가 분리되는 부분이 몸체(110)의 선단에 해당하게 되며, 몸체(110)의 기단은 니플(100)이 형성된 성형물에 해당하게 된다.In other words, the body 110 is formed by filling a resin formed in a cavity formed between the nipple sleeve and the core, and a flow path is formed to allow fluid to flow therein. The flow path formed inside the body 110 is formed by a core inserted into the nipple sleeve, and a portion from which the core is separated from the nipple sleeve corresponds to the front end of the body 110. The nipple 100 corresponds to a formed article.
이와 같은 몸체(110)의 선단 외측면에는 걸림턱(120)이 형성되는데, 걸림턱(120)은 몸체(110)의 선단과 조립되는 관로, 예를 들어 유체의 이동을 안내하는 튜브의 내측면을 압박하여 관로와 니플(100)의 기밀성을 향상시킴과 동시에 관로가 몸체(110)의 선단으로부터 무단으로 분리되지 않도록 강제하는 수단이 된다.A locking jaw 120 is formed on the outer side of the front end of the body 110, and the locking jaw 120 is a pipe that is assembled with the front end of the body 110, for example, an inner surface of a tube for guiding a fluid movement. Pressing to improve the airtightness of the conduit and the nipple (100) and at the same time is a means for forcing the conduit from being separated from the tip of the body (110) without permission.
이러한 걸림턱(120)은 상향경사구간(120a)과 하향경사구간(120c)으로 구성되는데, 상향경사구간(120a)은 몸체(110)의 선단에서 기단을 향해 점진적으로 두꺼워지도록 형성되며, 하향경사구간(120c)은 상향경사구간(120a)이 끝나는 지점에서 몸체(110)의 기단을 향해 점진적으로 얇아지도록 형성된다.The locking jaw 120 is composed of an upward inclination section 120a and a downward inclination section 120c. The upward inclination section 120a is formed to be gradually thickened toward the base at the tip of the body 110, and is inclined downward. The section 120c is formed to gradually become thinner toward the base end of the body 110 at the point where the upward slope section 120a ends.
이와 같이 걸림턱(120)이 상향경사구간(120a)과 하향경사구간(120c)으로 구성되면, 몸체(110)의 선단 외측면에서 기단을 향해 점진적으로 그 지름이 증가하다가 상향경사구간(120a)과 하향경사구간(120c)의 경계에서 그 지름이 점진적으로 감소하는 형태의 걸림턱(120)을 형성하게 된다.As such, when the locking jaw 120 is composed of an upward inclination section 120a and a downward inclination section 120c, the diameter gradually increases toward the base from the outer surface of the distal end of the body 110, and then the upward inclination section 120a. At the boundary between the downward slope and the downward slope 120c, the locking step 120 is formed to gradually decrease in diameter.
이에 따라, 관로가 니플(100)과 조립될 때 관로의 입구가 몸체(110)의 선단에 형성된 상향경사구간(120a)의 경사면에 안내되어 용이하게 삽입된다. 또한, 상기와 같은 걸림턱(120)은 상향경사구간(120a)과 하향경사구간(120c)의 경계에 대한 지름이 다른 부분에 비해 크기 때문에 관로를 압박하여 니플(100)과 관로의 기밀성을 향상시키게 된다.Accordingly, when the conduit is assembled with the nipple 100, the inlet of the conduit is guided to the inclined surface of the upward inclination section 120a formed at the tip of the body 110 to be easily inserted. In addition, the locking step 120 as described above because the diameter of the boundary between the uphill section (120a) and the downhill section (120c) is larger than the other parts to press the pipeline to improve the air tightness of the nipple (100) and the pipeline. Let's go.
한편, 몸체(110)의 선단 내측면은 그 두께가 몸체(110)의 기단 두께보다 얇게 형성되는 탄성변형구간(130)이 형성된다. 이와 같이 몸체(110)의 다른 부분에 비해 그 두께가 얇은 탄성변형구간(130)이 몸체(110)의 선단 내측면에 형성되면, 성형된 니플(100)이 니플 슬리브에서 취출될 때 몸체(110)의 선단이 오므라지게 되어 성형된 니플(100)의 파손없이 원활하게 니플 슬리브로부터 취출할 수 있게 된다.On the other hand, the tip inner surface of the body 110 is formed with an elastic deformation section 130, the thickness of which is formed to be thinner than the base thickness of the body (110). Thus, when the elastic deformation section 130 is thinner than other portions of the body 110 is formed on the tip inner surface of the body 110, when the molded nipple 100 is taken out of the nipple sleeve body 110 ), The tip end is retracted so that it can be taken out from the nipple sleeve smoothly without damaging the molded nipple 100.
즉, 탄성변형구간(130)은 도 3에 도시된 바와 같이 몸체(110)의 다른 부분에 비해 그 두께가 얇게 형성되는데, 바람직하게 탄성변형구간(130)은 몸체(110)의 기단 두께의 1/2에 해당하게 형성된다.That is, the elastic deformation section 130 is thinner than the other parts of the body 110, as shown in Figure 3 is formed thin, preferably the elastic deformation section 130 is 1 of the base thickness of the body 110 It corresponds to / 2.
또한, 탄성변형구간(130)은 몸체(110)의 선단에서 걸림턱(120)이 끝나는 지점에 걸쳐 형성되되, 탄성변형구간(130)이 끝나는 부분은 경사면(132)을 형성하여 탄성변형구간(130)의 두께가 몸체(110)의 기단으로 갈수록 점진적으로 두꺼워지게 형성된다.In addition, the elastic deformation section 130 is formed over the end of the locking jaw 120 at the tip of the body 110, the portion where the elastic deformation section 130 is formed to form an inclined surface 132 elastic deformation section ( The thickness of 130 is gradually thickened toward the base end of the body 110.
이렇게 탄성변형구간(130)이 얇게 형성되면 니플 슬리브에서 성형된 니플(100)이 취출될 때 몸체(110)의 선단에 대한 탄성력이 향상되어 니플이 파손되지 않고 원할하게 니플 슬리브로부터 취출된다.When the elastic deformation section 130 is thinly formed, when the nipple 100 formed in the nipple sleeve is taken out, the elastic force on the tip of the body 110 is improved, and the nipple is smoothly taken out from the nipple sleeve without being damaged.
즉, 니플 슬리브와 코어 사이에 형성된 캐비티는 몸체(110)를 형성하는 제1캐비티와 걸림턱(120)을 형성하는 제2캐비티로 구성되어 몸체(110)를 형성하는 제1캐비티와 걸림턱(120)을 형성하는 제2캐비티에 수지가 채워져 니플(100)을 성형하게 된다.That is, the cavity formed between the nipple sleeve and the core is composed of a first cavity forming the body 110 and a second cavity forming the locking jaw 120 to form the first cavity and the locking jaw (which forms the body 110). The resin is filled in the second cavity forming the 120 to form the nipple 100.
이렇게 니플(100)이 성형된 후에는 니플 슬리브에서 성형이 완료된 니플(100)을 취출하게 되는데, 이때 니플(100)은 코어와 대향하는 니플 슬리브의 타측을 통해 취출된다.After the nipple 100 is molded in this way, the nipple 100 is removed from the nipple sleeve, and the nipple 100 is taken out through the other side of the nipple sleeve facing the core.
이에 따라, 니플(100)의 선단 외측면에 형성된 걸림턱(120)이 제2캐비티로부터 제1캐비티로 이동하게 되는데, 제1캐비티는 제2캐비티에 비해 그 지름이 감소하게 되어 니플(100)의 걸림턱(120)이 제1캐비티로 이동하는 것에 따라 걸림턱(120)의 높이만큼 몸체(110)의 선단 내측에 형성된 탄성변형구간(130)이 오므라드는 탄성변형이 발생하여 니플(100)을 원활하게 취출할 수 있게 된다.Accordingly, the locking jaw 120 formed on the outer surface of the front end of the nipple 100 moves from the second cavity to the first cavity, and the diameter of the first cavity is reduced compared to the second cavity, so that the nipple 100 As the latching jaw 120 moves to the first cavity, the elastic deformation section 130 formed inside the tip of the body 110 as the height of the locking jaw 120 is retracted to generate the nipple 100. Can be taken out smoothly.
상기와 같은 본 발명에 따른 니플(100)은 니플 슬리브와 코어 사이에 형성된 캐비티에 수지가 채워져 니플이 성형되고, 성형된 니플(100)은 코어와 대향하는 니플의 기단을 통해 취출됨으로써 니플의 외측면에 버와 같은 파팅 라인이 형성되지 않아 니플(100)과 관로의 조립 중에 관로가 버에 의해 찢어지는 것을 방지하게 되고 니플(100)과 관로를 기밀하게 밀착시킬 수 있어 누수를 방지할 수 있을 뿐만 아니라 버를 제거하기 위한 별도의 가공이 필요없기 때문에 생산성이 향상된다.The nipple 100 according to the present invention as described above is filled with a resin in the cavity formed between the nipple sleeve and the core, the nipple is molded, the molded nipple 100 is taken out through the base of the nipple facing the core to the outside of the nipple Parting lines such as burrs are not formed on the side to prevent the pipes from being torn by the burrs during assembly of the nipples 100 and the pipes, and the nipples 100 and the pipes can be tightly sealed to prevent leakage. In addition, productivity is improved because no additional machining is required to remove the burr.
또한, 몸체(110)의 선단 내측면에 탄성변형구간이 형성됨으로써, 니플 슬리브에서 성형된 니플(100)이 취출될 때 니플의 걸림턱(120)이 제2캐비티에서 제1캐비티로 이동하는 것에 따라 걸림턱(120)의 높이만큼 탄성변형구간(130)이 오므라드는 탄성변형이 발생하여 니플(100)을 원활하게 취출할 수 있다.In addition, the elastic deformation section is formed on the inner surface of the front end of the body 110, so that when the nipple 100 formed in the nipple sleeve is taken out, the locking jaw 120 of the nipple moves from the second cavity to the first cavity. Accordingly, an elastic deformation occurs when the elastic deformation section 130 is retracted by the height of the locking jaw 120, so that the nipple 100 may be smoothly taken out.
한편, 본 발명은 앞서 설명한 실시예로 한정되는 것이 아니라 본 발명의 요지를 벗어나지 않는 범위 내에서 수정 및 변형하여 실시할 수 있고, 그러한 수정 및 변형이 가해진 것도 본 발명의 기술적 사상에 속하는 것으로 보아야 한다.Meanwhile, the present invention is not limited to the above-described embodiments, but may be modified and modified without departing from the scope of the present invention, and such modifications and variations should be regarded as belonging to the technical spirit of the present invention. .
예를 들어, 몸체(110)의 선단에 대한 강성을 향상시키거나 탄성변형구간(130)에 대한 탄성력이 향상되도록 몸체(110)의 내측면에 보강 리브(112), 함몰부(120c), 절개홈(114)이 마련될 수도 있을 것이다. 이를 도 4 내지 도 9에 의거하여 설명한다.For example, reinforcing ribs 112, depressions 120c, incisions on the inner surface of the body 110 to improve the rigidity of the front end of the body 110 or the elastic force for the elastic deformation section 130 is improved. Groove 114 may be provided. This will be described with reference to FIGS. 4 to 9.
제 2 실시예Second embodiment
도 4는 본 발명에 따른 파팅 라인이 없는 니플의 제2실시예를 나타낸 단면 사시도이고, 도 5는 본 발명의 제2실시예에 따른 파팅 라인이 없는 니플을 나타낸 단면도이다.4 is a sectional perspective view showing a second embodiment of a nipple without a parting line according to the present invention, and FIG. 5 is a sectional view showing a nipple without a parting line according to a second embodiment of the present invention.
도면을 참조하여 설명하며, 제 2 실시예에 따른 니플(100)은 몸체(110)의 내측면 둘레를 따라 간헐적으로 보강 리브(112)가 형성된다. 이때, 보강 리브(112)는 몸체(110)의 축선방향으로 연장되는데, 보강 리브(112)가 형성된 부분은 몸체(110)의 선단 내측면에서 탄성변형구간(130)이 형성된 지점에 걸쳐 형성된다.The nipple 100 according to the second embodiment of the present invention will be described with reference to the drawings, and the reinforcement ribs 112 are formed intermittently along the inner circumference of the body 110. At this time, the reinforcing rib 112 extends in the axial direction of the body 110, the portion in which the reinforcing rib 112 is formed is formed over the point where the elastic deformation section 130 is formed on the inner side of the front end of the body 110. .
이와 같이 몸체(110)의 내측면에 보강 리브(112)가 형성되면 성형된 니플의 선단에 외력이 가해지더라도 보강 리브(112)에 의해 니플의 선단에 대한 강성이 보강되어 니플의 선단이 쉽게 파손되지 않는다.When the reinforcing rib 112 is formed on the inner surface of the body 110 as described above, even if an external force is applied to the tip of the molded nipple, the rigidity of the nipple is reinforced by the reinforcing rib 112 and the tip of the nipple is easily broken. It doesn't work.
또한, 보강 리브(112)가 몸체(110)의 축선방향으로 연장되고, 보강 리브(112)가 형성된 부분이 몸체(110)의 선단 내측면에서 탄성변형이 형성된 지점에 해당하기 때문에 니플 슬리브에서 성형된 니플이 취출될 때 탄성변형구간(130)에 대한 탄성변형에 영향을 주지 않고 안정적으로 오므라들어 니플의 취출을 용이하게 한다.In addition, since the reinforcing rib 112 extends in the axial direction of the body 110 and the portion where the reinforcing rib 112 is formed corresponds to the point where the elastic deformation is formed at the inner side of the front end of the body 110, the nipple is formed in the nipple sleeve. When the nipple is taken out, the nipple is stably retracted without affecting the elastic deformation of the elastic deformation section 130 to facilitate the extraction of the nipple.
이러한 보강 리브(112)는 도 4 및 도 5에 도시된 바와 같이 몸체(110)의 내측면 둘레를 따라 간헐적으로 형성될 수도 있지만 경우에 따라서는 도 10 및 도 11에 도시된 바와 같이 몸체(110)의 내측면 둘레를 따라 조밀하게 형성되어 마치 세레이션(serration)과 같은 형태로 형성될 수도 있다.The reinforcing ribs 112 may be formed intermittently along the inner circumference of the body 110 as shown in FIGS. 4 and 5, but in some cases the body 110 as shown in FIGS. 10 and 11. Densely formed along the inner circumference of the c) may be formed as a serration.
제 3 실시예Third embodiment
도 6은 본 발명에 따른 파팅 라인이 없는 니플의 제3실시예를 나타낸 사시도이고, 도 7은 본 발명의 제3실시예에 따른 파팅 라인이 없는 니플을 나타낸 단면도이다.6 is a perspective view showing a third embodiment of the nipple without the parting line according to the present invention, Figure 7 is a cross-sectional view showing a nipple without the parting line according to the third embodiment of the present invention.
도면을 참조하여 설명하며, 제 3 실시예에 따른 니플(100)은 걸림턱(120)의 둘레를 따라 간헐적으로 함몰부(120c)가 형성된다. 이러한 함몰부(120c)는 앞서 설명한 보강 리브(112)와 유사하게 상향경사구간(120a)과 하향경사구간(120c)을 통과하도록 몸체(110)의 축선방향으로 연장된다.Referring to the drawings, the nipple 100 according to the third embodiment is formed with an intermittent depression (120c) along the circumference of the locking projection (120). The depression 120c extends in the axial direction of the body 110 to pass through the upward slope 120a and the downward slope 120c similarly to the reinforcement rib 112 described above.
