Description

안경코받침용 심재의 사출금형{A injection metallic mold duramen for eyeglasses bridge}A injection metallic mold duramen for eyeglasses bridge}

본 발명은 안경코받침용 심재의 사출금형에 관한 것으로, 좀 더 상세하게는 폴리카보나이트(POLY CARBONATE)재질로 심재를 사출성형하는 금형을 개량하여 금형분리선이 없는 심재를 제공하고 또, 금형에서 심재와 원료사출물줄기가 배출될 때 심재가 원료사출물줄기로부터 떨어지도록 하여 품질이 우수한 심재를 간편하게 생산할 수 있도록 한 것이다.The present invention relates to an injection mold of a core material for eyeglass nose support, and more particularly, to improve the mold for injection molding the core material with a poly carbonite (POLY CARBONATE) material to provide a core material without a mold separation line, and the core material in the mold When the raw material injection stem is discharged, the core material is separated from the raw material injection stem so that the core material can be easily produced with high quality.

일반적으로 안경코받침(50)은 도 10에서 보는 바와 같이 코에 밀착되는 연질의 코받침부(51)와 코받침부(51)를 안경테의 코받침연결간에 연결하기 위한 심재(52)로 구성되어 있으며 또, 심재(52)는 도 12에서 보는 바와 같이 머리부(53)와 연결부(54)로 구성되어 있다.In general, the eyeglass nose support 50 is composed of a core material 52 for connecting between the soft nose support 51 and the nose support 51 that is in close contact with the nose as shown in FIG. Moreover, the core material 52 is comprised from the head part 53 and the connection part 54 as shown in FIG.

이와 같은 안경코받침(50)은 심재(52)를 별도로 제조한 후에 심재를 안경코받침 성형용 금형에 넣고, 심재(52)의 머리부(53)가 코받침부(51)에 매립되도록 사출성형하여 구성되는 것이다.The eyeglass nose support 50 is manufactured by separately manufacturing the core material 52, and then inserting the core material into the mold for eyeglass nose support molding, and ejecting the head 53 of the core material 52 to be embedded in the nose support part 51. It is formed by molding.

상기와 같이 안경코받침을 구성하는 심재는 금속 또는 폴리카보나이트 재질로 구성되는데 금속으로 된 심재는 제조공정이 여러단계로 이루어지기 때문에 생산능률이 떨어지고, 특히 안경코받침을 형성하였을 때 코받침부가 대부분 투명이기 때문에 금속 특유의 색상이 투시되므로 외관상으로 보기에 좋지 않고 또, 무게가 무거워지는 단점이 있다.As described above, the core material constituting the eyeglass nose support is made of metal or polycarbonite material, but the metal core material has low production efficiency because the manufacturing process is performed in several stages, and especially when the nose support part is formed, most of the nose support part is formed. Since it is transparent, the color peculiar to the metal is transparent, which is not good in appearance and has a disadvantage of being heavy.

상기와 같은 단점들을 해결하기 위하여 합성수지 중에 폴리카보나이트 재질로 심재를 사출성형하여 사용하고 있다.In order to solve the above disadvantages, the core material is injection molded using a polycarbonate material in synthetic resin.

종래 상기와 같은 폴리카보나이트 재질로 된 심재를 사출성형하기 위한 금형을 도 11에서 구체적으로 살펴 보면, 금형(60)에 형성된 심재성형홈(61)이 T자형으로 분리되도록 구성되어 있는데, 좀 더 구체적으로는 머리부(62)의 밑면으로 금형분리선이 형성되어 있고 또, 연결부홈(63)의 중심으로 금형분리선(66)이 형성되어 있다.Looking at the mold for injection molding the core material made of a polycarbonite material as described above in detail in Figure 11, the core molding groove 61 formed in the mold 60 is configured to be separated into a T-shaped, more specifically The mold separation line is formed in the bottom surface of the head 62, and the mold separation line 66 is formed in the center of the connection part groove 63. As shown in FIG.

상기와 같이 구성된 금형(60)으로 심재(52)를 사출성형하면 심재(52)의 연결부(54)의 중심으로 형성된 금형분리선(55)이 투시되기 때문에 외관상으로 보기에 좋지 않다.Injection molding the core 52 with the mold 60 configured as described above is not good in appearance because the mold separation line 55 formed at the center of the connecting portion 54 of the core 52 is projected.

또한, 금형(60)의 구조상에서 탕로(64)가 연결부(63)의 후미에 형성되어 있기 때문에 심재를 성형한 후, 탈형할 때 심재(52)와 원료사출물줄기(65)가 같이 붙어 있는 상태에서 배출된다.In addition, since the hot water path 64 is formed at the rear of the connecting portion 63 in the structure of the mold 60, the core material 52 and the raw material injection stem 65 are attached together when the core material is molded and then demolded. Discharged.

그렇기 때문에 원료사출물줄기와 붙어 있는 심재를 하나씩 손으로 떼어내는 작업을 해야하는 불편이 있고, 이와 같은 이유로 인하여 생산능률이 떨어지는 등의문제점이 있다.Therefore, it is inconvenient to remove the raw material injection stem and the attached core material by hand one by one, there is a problem such as the production efficiency is lowered for this reason.

본 발명은 상기한 바와 같이 심재의 연결부를 중심으로 금형분리선이 형성되는 단점과, 사출성형 후에 원료사출물줄기와 심재가 같이 붙어 있기 때문에 하나씩 손으로 떼어내는 불편 등 제반 문제점을 해결하기 위한 것이 본 발명의 목적이며,상기의 목적을 달성하기 위하여 금형을 양분하여 사출부측와 이젝터측에 각각 설치하며, 사출부측에 고정되는 금형에는 심재머리홈을 형성하고, 이젝터측에 고정되는 금형에는 연결부홈을 단일체로 형성하여 금형분리선이 없는 심재를 사출성형할 수 있고 또, 이젝터측 금형에서 심재와 원료사출물줄기가 배출될 때 심재가 원료사출물줄기로부터 떨어지도록 구성하여 품질이 우수한 심재를 간편하게 생산할 수 있도록 한 것이다.The present invention is to solve the problems of the mold separation line is formed around the core of the core as described above, and the problems such as the inconvenience of peeling off one by one because the raw material injection stem and the core is stuck together after injection molding In order to achieve the above object, the mold is divided into two parts and installed on the injection part side and the ejector side, respectively, and the core fixed to the injection part forms a core head groove, and the mold fixed to the ejector side has a single connection part groove. The core material can be injection molded without a mold separation line, and when the core material and raw material injection stem are discharged from the ejector mold, the core material is separated from the raw material injection stem so that it can be easily produced. .

도면의 미설명 부호 40은 안내편, 41은 복귀스프링, 42는 원료사출물줄기를 표시한 것이다.In the drawings, reference numeral 40 denotes a guide piece, 41 denotes a return spring, and 42 denotes a raw material injection stem.

이와 같이 구성된 본 발명의 안경코받침용 심재의 사출금형에 관한 작용을 상세히 설명하면 다음과 같다.Referring to the operation of the injection mold of the eyeglass nose rest core material of the present invention configured as described above in detail as follows.

사출금형체(1)를 구성하는 사출부측(2)과 이젝터측(3)을 사출기(도시하지 않음)에 설치한다.The injection part side 2 and the ejector side 3 constituting the injection mold 1 are provided in an injection machine (not shown).

상기와 같이 사출금형체(1)를 설치한 상태에서 사출부측(2)에 이젝터측(3)을 접근시켜 상기에 고정된 금형(4)(6)을 서로 밀착하면 도 3에서 보는 바와 같이 사출부측(2)에 고정한 금형(4)과 이젝터측(3)에 고정한 금형(6) 사이에 A 타입의 심재(25)를 구성하는 심재머리홈(5)(5')들과 단홈(7)(7')과 연결부홈(8)(8')들이 연결된 공간들이 만들어 지고 또 사출부측탕로(9)와 이젝터측탕로(9')가 복개되며 한편, 가동편(13)(13')에 고정된 핀(12)(12')들이 연결부홈(8)(8')을 관통하여 설치된다.When the injection mold body 1 is installed as described above, the ejector side 3 approaches the ejector side 3, and the molds 4 and 6 fixed thereto are brought into close contact with each other. The core head grooves 5, 5 'and the step groove 7 constituting the A-type core material 25 between the mold 4 fixed to the side 2 and the mold 6 fixed to the ejector side 3 The spaces where the 7 'and the connection grooves 8 and 8' are connected are made, and the ejection part side flow path 9 and the ejector side flow path 9 'are opened, while the movable pieces 13 and 13'. Pins 12 and 12 'fixed thereto are installed through the connection grooves 8 and 8'.

이와 같은 상태는 심재머리홈(5)(5')들과, 단홈(7)(7') 및 연결부홈(8)(8')들이 원료투입공(11)(11')들과, 사출부측탕로(9)와, 이젝터측탕로(9')와 원료유입구(10)와 연결된다.In this state, the core head grooves 5, 5 ', the step grooves 7, 7' and the connection grooves 8, 8 'are made of raw material injection holes 11, 11', and injection. It is connected to the sub-side passage 9, the ejector side passage 9 'and the raw material inlet 10.

상기와 같은 상태에서 원료유입구(10)로 원료를 사출시키면 사출부측탕로(9)와 이젝터측탕로(9')와 원료투입공(11)(11')들을 경유하여 먼저, 연결부홈(8)(8')들과 단홈(7)(7')들과 심재머리홈(5)(5')들로 공급되어 A 타입의 심재(25)가 성형된다.When the raw material is injected into the raw material inlet 10 in the above state, first, the connection part groove 8 via the injection part side flow path 9, the ejector side flow path 9 'and the raw material injection holes 11 and 11'. ) 8 ', the step grooves 7 and 7' and the core head grooves 5 and 5 'are supplied to form an A-type core 25.

상기와 같은 과정으로 A 타입의 심재(25)가 성형되면 도 4에서 보는 바와 같이 이젝터측(3)이 사출부측(2)으로 분리된다.When the core material 25 of the A type is molded in the above-described process, the ejector side 3 is separated into the ejection part side 2 as shown in FIG. 4.

그러면 경사안내봉(14)(14')이 경사안내구멍(15)(15')에서 빠지면서 경사각에 의해서 가동편(13)(13')를 좌우로 벌려주게 되므로 가동편(13)(13')에 설치된 핀(12)(12')도 연결부홈(8)(8')로부터 빠진다.Then, the inclined guide rods 14 and 14 'are removed from the inclined guide holes 15 and 15', and thus the movable pieces 13 and 13 'are opened to the left and right by the inclination angle. The pins 12 and 12 'provided in the pin 1) also come out of the connecting groove 8 and 8'.

그리고, 이젝터측(3)의 금형(6)에 형성된 연결부홈(8)(8')들의 뒷부분에 설치된 이젝터핀(16)(16')들과 또 이젝터측탕로(9')에 일정한 간격으로 설치된 이젝터핀(17)들이 전진하여 도 5에서 보는 바와 같이 이젝터핀(16)(16')은 A 타입의 심재(25)를 밀어내고 동시에 이젝터핀(17)들은 원료사출물줄기(42)를 밀어낸다.Then, at regular intervals, the ejector pins 16 and 16 'and the ejector side water heater 9' are provided at the rear of the connection grooves 8 and 8 'formed in the mold 6 on the ejector side 3. As the ejector pins 17 are installed to move forward, the ejector pins 16 and 16 'push out the A type core 25 and the ejector pins 17 push the raw material injection stem 42 at the same time. Serve

그러면 A 타입의 심재(25)가 원료사출물줄기(42)로부터 자동적으로 떨어지면서 금형(6)에서 배출되는 것이다.Then, the core type 25 of the A type is discharged from the mold 6 while automatically falling from the raw material injection stem 42.

그리고, 도 9에서 도시한 것과 같은 B 타입의 심재(26)를 사출성형하는 것도 상기한 A타입의 심재(25)를 사출하는 것과 같으나 사출부측(2)의 금형(4)에 형성된 심재머리홈(5)(5')들과 이젝터측(3)의 금형(6)에 형성된 연결부홈(8)(8')들은 전기한 것을 기준으로 90도 방향으로 전환하여 구성하고 있기 때문에 연결부홈(8)(8')의 양쪽에 가동편(13)(13')에 의해서 작동하는 각핀(19)(19')의 작용으로 심재의 연결부의 양쪽에 각홈(C)이 형성된다.In addition, the injection molding of the B type core material 26 as shown in FIG. 9 is the same as the injection of the core material 25 of the A type described above, but the core head groove formed in the mold 4 of the injection part side 2. (5) (5 ') and the connection groove (8) (8') formed in the mold 6 of the ejector side (3) is connected to the groove of the connection portion (8 ') because it is configured in a 90 degree direction on the basis of the foregoing Angle grooves C are formed on both sides of the connecting portion of the core by the action of the angle pins 19 and 19 'actuated by the movable pieces 13 and 13' on both sides of the 8 '.

이상과 같은 본 발명은 심재머리홈과 단홈 사이에서만 금형이 분리되고 연결부홈은 단일체로 구성되어 있기 때문에 심재의 중심으로 금형분리선이 형성되지 않아 외관상으로 미려한 효과가 있고, 심재와 원료사출물줄기가 금형에서 배출되는 동시에 분리되기 때문에 별도로 심재를 분리하는 작업을 하지 않아도 되므로 작업공정이 간편하여 생산능률을 향상시키는 효과가 있다.In the present invention as described above, since the mold is separated only between the core head groove and the end groove, and the connection part groove is composed of a single body, the mold separation line is not formed at the center of the core material, so that the appearance is beautiful, and the core material and the raw material injection stem are molds. Since it is discharged at the same time and separated from the core, it is not necessary to separate the core material, so the work process is simple and the production efficiency is improved.
