The plastic tube is a method in which a plastic raw material is injected into a molding machine and extruded, and the molded extrudate is cooled, that is, a plastic raw material is fed into a hopper And then the product is completed through extrusion, molding, cooling and cutting processes. During the process of making plastic moldings, the cooling process plays an important role in the quality of the product. Generally, there are air-cooled and water-cooled types of cooling.

The main ring 10 is formed on the rear side of the first hollow portion 11a into which the extrudate flows, the second hollow portion 11b formed on the rear side of the first hollow portion 11a and the second hollow portion 11b, A first body 12 including a third hollow portion 11c having a larger diameter than the two hollow portions 11b; And the front portion is inserted into the second hollow portion 11b so as to be spaced apart from the rear portion of the second hollow portion 11b. The rear portion of the second hollow portion 11c is in contact with the third hollow portion 11c and the projection 14 is formed along the longitudinal direction of the rear portion, And a second main body 16 communicating with the first portion 11a.

제1 본체(12)는 본체링(10)의 전면에 해당되고, 내부에 중공부가 3단계로 형성된다. 제1 중공부(11a)는 압출된 성형물이 최초로 유입되는 곳으로서, 제1 중공부(11a)는 도 4(a)에 도시된 바와 같이 전방에서 후방으로 갈수록 직경이 작아지도록 형성되어 압출 성형물이 제1 중공부(11a)로 유입 시 진입로를 벗어나 진입하여도 제1 중공부(11a)로 자연스럽게 유입된다. 제1 중공부(11a) 후측으로는 제2 중공부(11b)가 형성되는데, 제2 중공부(11b)는 직경이 제1 중공부(11a)의 후방보다 크도록 형성되고, 후술할 제2 본체(16)의 전면부가 삽입된다. 이때, 제1 본체(12) 내부 중 제1 중공부(11a)에서 제2 중공부(11b)로 넘어가는 경계에는 단턱(J)이 경사지게 형성되는데, 이와 관련한 사항은 후술한다.The first body 12 corresponds to the front surface of the main body ring 10, and the hollow portion is formed in three stages. 4 (a), the first hollow portion 11a is formed so that its diameter decreases from the front to the rear as shown in FIG. 4 (a), so that the extrudate And flows into the first hollow portion 11a naturally even when entering the first hollow portion 11a and entering the entrance hollow. A second hollow portion 11b is formed on the rear side of the first hollow portion 11a. The second hollow portion 11b is formed such that its diameter is larger than the rear of the first hollow portion 11a. The front portion of the main body 16 is inserted.

한편, 제1 본체(12)에는 도 3에 도시된 바와 같이 제3 중공부(11c)와 연통되는 냉각수 유입홀(13)이 형성되어 본체링(10)에서 분사시키기 위한 냉각수가 냉각수 유입홀(13)을 통해 유입된다.3, a cooling water inflow hole 13 communicating with the third hollow portion 11c is formed in the first main body 12 so that cooling water for jetting from the main ring 10 flows into the cooling water inflow hole 13).

제2 본체(16)는 본체링(10)의 후면에 해당되고, 내부에는 제1 중공부(11a)와 연통되는 중공부가 형성된다. 제2 본체(16) 전면부의 직경은 제2 중공부(11b)보다 작게 형성되어 제2 중공부(11b)에 이격되어 삽입된다. 이에 따라 제1 본체(12) 및 제2 본체(16) 사이 중 제2 중공부(11b) 상에 제1 유로(R1)가 형성된다.The second body 16 corresponds to the rear surface of the main body ring 10, and a hollow portion communicating with the first hollow portion 11a is formed therein. The diameter of the front portion of the second body 16 is smaller than that of the second hollow portion 11b and inserted into the second hollow portion 11b. Accordingly, the first flow path R1 is formed on the second hollow portion 11b of the first main body 12 and the second main body 16.

한편 제2 본체(16)의 전방 단부는 도 3에 도시된 바와 같이 단턱(J)의 경사와 같은 각도로 경사지게 형성되는데, 이와 관련한 사항은 후술한다.3, the front end of the second body 16 is formed to be inclined at the same angle as the inclination of the step J, and the matters related thereto will be described later.

제2 본체(16) 후면부는 제3 중공부(11c)에 억지끼움되도록 형성되어 제2 본체(16)가 제1 본체(12)에 결합될 수 있도록 한다. 이때, 제2 본체(16)에는 도 4(b)에 도시된 바와 같이 제2 본체(16) 후면부 테두리 길이방향을 따라 돌출부(14)가 형성되는데, 이는 제2 본체(16)가 제1 본체(12)에 억지끼움결합될 때 제1 본체(12) 및 제2 본체(16) 사이 중 제3 중공부(11c) 상에 소정 크기의 제2 유로(R2)가 형성되도록 하고, 제1 본체(12)의 단턱(J)과 제2 본체(16)의 전방 단부 사이에 소정 크기의 틈이 형성되도록 하기 위함이다. 또한 제2 유로(R2)는 제1 유로(R1)와 연통되고, 냉각수 유입홀(13)과도 연통된다.The rear portion of the second body 16 is configured to be pressed against the third hollow portion 11c so that the second body 16 can be coupled to the first body 12. [ 4 (b), the protruding portion 14 is formed along the longitudinal direction of the rear portion of the second body 16, as shown in FIG. 4 (b) A second flow path R2 of a predetermined size is formed on the third hollow portion 11c of the first main body 12 and the second main body 16 when the second flow path R2 is tightly coupled to the first main body 12, A gap of a predetermined size is formed between the step J of the first body 12 and the front end of the second body 16. [ The second flow path (R2) communicates with the first flow path (R1) and communicates with the cooling water inflow hole (13).

분사슬릿(20)은 제1 본체(12)의 단턱(J)과 제2 본체(16) 전면부의 전방 단부 사이에 형성되고, 제1 유로(R1) 및 제2 유로(R2)를 통해 냉각수 유입홀(13)과 연통되어 냉각수 유입홀(13)로 유입된 냉각수가 분사된다. 분사슬릿(20)은 전술한 바와 같이 경사지게 형성된 단턱(J) 및 제2 본체(16)의 전방 단부로 인하여 분사 시에 방향성을 갖게 되는데, 바람직하게는 도 3에 도시된 바와 같이 단턱(J) 및 제2 본체(16)의 전방 단부의 경사가 압출 성형물이 진행하는 방향으로 형성되어 압출 성형물에 수막이 효율적으로 형성되도록 한다. 또한 분사슬릿(20)은 본체링(10) 내주연에 연속적으로 형성되기 때문에 냉각수가 압출 성형물(T)에 고르게 분사되고, 압출 성형물(T)이 받는 수압도 고르게 된다. 이에 따라 압출 성형물(T)에 수막이 고르게 형성되며 수압에 의한 부분적인 변형도 없게 되어 압출 성형물(T)의 표면이 매끄럽게 형성된다.The injection slit 20 is formed between the step J of the first main body 12 and the front end of the front portion of the second main body 16 and flows through the first flow path R1 and the second flow path R2, And the cooling water flowing into the cooling water inflow hole (13) is communicated with the hole (13). The jetting slit 20 has a directionality at the time of jetting due to the inclined step J and the front end of the second body 16 as described above. Preferably, the jetting slit 20 has a step J, And the inclination of the front end of the second body 16 are formed in a direction in which the extrudate advances, so that the extruded body can be efficiently formed. Further, since the injection slit 20 is continuously formed in the periphery of the main ring 10, the cooling water is uniformly sprayed on the extrudate T, and the water pressure to which the extrudate T is subjected is also uniform. As a result, the water film is uniformly formed on the extrudate T, and there is no partial deformation due to water pressure, so that the surface of the extrudate T is smoothly formed.
