상기 체크링(100)과 접촉되는 원뿔헤드(121)의 저면부위에는 일정두께로 이종금속의 용접봉을 용접 코팅하여 융착시킨 하부용접코팅부(124)를 형성하여 된 스크류헤드부(120)로 구성된다.The bottom portion of the conical head 121 in contact with the check ring 100 consists of a screw head portion 120 formed by forming a lower welding coating portion 124 welded and fused by welding electrodes of different metals to a predetermined thickness. do.

여기서 상기 체크링(100)에 형성된 표면용접코팅부는 일정한 간격을 두고 복수개의 표면용접코팅부(101) 및 표면용접코팅부(102)로 형성할 수 있다.Here, the surface welding coating part formed on the check ring 100 may be formed of a plurality of surface welding coating part 101 and the surface welding coating part 102 at regular intervals.

또한, 상기 이종금속은 SACM645계열, SUS계열의 특수강 등, 스크류 헤드 세트의 각 부품의 모재 보다는 금속간 내마모, 내부식, 내열성이 뛰어난 금속으로 제작된다.In addition, the dissimilar metal is made of a metal having excellent wear resistance, corrosion resistance, and heat resistance between metals rather than the base metal of each component of the screw head set, such as SACM645 series and SUS series special steel.

또한 상기 용접방법은 어떤 방법을 이용하여 제작하더라도 관계없다.The welding method may be produced using any method.

미 설명부호 실링(110)의 112는 요입부이며, 스크류헤드부(120)의 122는 축부, 123은 나사부이다.Reference numeral 112 of the seal 110 is a concave portion, 122 of the screw head portion 120 is the shaft portion, 123 is a screw portion.

여기서, 상기 체크링(100)의 표면용접코팅부(102)(103)를 제작하는 방법을 도 5를 참조하여 설명한다. Here, a method of manufacturing the surface welding coating parts 102 and 103 of the check ring 100 will be described with reference to FIG. 5.

먼저, 도 5의 (a)와 같이 모재의 외주면 둘레에 일정간격으로 일정깊이 및 폭으로 절삭하여 용접홈(S1)을 형성하여 준다.First, as shown in (a) of FIG. 5, the welding groove S1 is formed by cutting a predetermined depth and width around the outer circumferential surface of the base material at a predetermined interval.

그리고 도 5의 (b)와 같이 상기 형성된 용접홈(S1)에 용접봉을 녹여 용접 코팅(S2)을 수행한다.And as shown in Figure 5 (b) to melt the welding rod in the formed welding groove (S1) to perform a welding coating (S2).

그리고 도 5의 (c)와 같이 모재의 표면을 가공하여 용접홈에 코팅된 용접코팅(S3) 부위가 모재의 외주면 부위와 일치하도록 가공하여 준다.And as shown in Figure 5 (c) by processing the surface of the base material is coated so that the welding coating (S3) portion coated on the welding groove coincides with the outer peripheral surface portion of the base material.

그리고 난후, 모재의 내부면을 절삭(S4)하여 형상가공을 수행함으로서 체크링(100)을 성형한다.Then, after cutting the internal surface of the base material (S4) by performing the shape processing to form the check ring (100).

이와 같이 표면용접코팅부(102)(103)가 형성된 체크링(100)이 성형 완료되면, 상기 체크링(100)의 양 측면에 다시 용접봉을 녹여 용접 코팅을 수행한 후, 상기 용접 코팅 두께가 일정한 두께가 되도록 가공하여 측면용접코팅부(104) 및 측면용접코팅부(105)를 각각 성형하여 준다.When the check ring 100 on which the surface welding coatings 102 and 103 are formed is completed as described above, after the welding rod is melted on both sides of the check ring 100 to perform welding coating, the thickness of the welding coating is increased. Processed to a certain thickness to form the side welding coating portion 104 and the side welding coating portion 105, respectively.

또한, 상기 실링(110)의 상부용접코팅부(113)와, 상기 스크류헤드부(120)의 저면용접코팅부(124)도 각 해당부위에 용접봉을 녹여 용접 코팅을 수행한 후, 상기 용접 코팅 두께가 일정한 두께가 되도록 가공하여 성형하게 된다.In addition, the upper welding coating part 113 of the sealing 110 and the bottom welding coating part 124 of the screw head part 120 also melt a welding rod on each corresponding part to perform welding coating, and then the welding coating. The thickness is processed to form a constant thickness.

이와 같이 구성된 본 발명에 따르자면, 상기 스크류 헤드 세트는 사출기 운전 구동 시 체크링(100)의 경우, 체크링(100)이 전후 왕복 동작을 수행할 때 체크링의 외주면과 실린더헤드(60)의 내면이 접촉되어 체크링의 외주면이 마모됨에 있어서, 상기 체크링(100)의 외주면에 형성된 표면용접코팅부(102)(103)에 의해 마모 진행 속도가 느리게 진행되어 수명이 연장되는 효과를 가져온다.According to the present invention configured as described above, the screw head set of the check ring 100 when driving the injection molding machine, when the check ring 100 performs the front and rear reciprocating operation of the outer peripheral surface of the check ring and the cylinder head 60 When the inner surface is in contact with the outer circumferential surface of the check ring is worn, by the surface welding coating parts 102 and 103 formed on the outer circumferential surface of the check ring 100, the progress of wear progresses slowly, resulting in an extended life.

동시에 상기 체크링(100)과 접촉되는 실링(110) 및 스크류헤드부(120)의 경우에도, 상기 체크링(100)과 접촉되는 부위에, 체크링의 경우 측면용접코팅부(104)(105)가, 실링(110)의 경우 상부용접코팅부(113)가, 스크류헤드부(120)의 경우 저면용접코팅부(124)가 서로 접촉됨으로써, 모재가 손상되는 것을 1차로 방지하여 주게 되어 그 만큼 마모 속도를 느리게 하고, 또 수명을 증가시키게 된다.
In the case of the seal 110 and the screw head 120 in contact with the check ring 100 at the same time, the side contact coating portion 104, 105 in the case of the check ring in the contact area with the check ring 100 In the case of the sealing 110, the upper welding coating portion 113, in the case of the screw head 120, the bottom welding coating portion 124 is in contact with each other, thereby primarily preventing the base material from being damaged. This slows down the wear rate and increases the service life.
