본 고안은 합성수지제의 체결구 몸체에 체결 철선을 일체로 사출 성형토록 된 체결구 사출 금형에 관한 것이다.The present invention relates to a fastener injection mold for injection molding the fastening wire integrally to the fastener body made of synthetic resin.
종래에 체결 철선이 일체로 성형된 체결구의 몸체를 제조하기 위하여 금형 상부에 요홈을 형성하며 자석을 설치하여 자석에 체결 철선을 부착시키고 양쪽 금형을 결합시켜 체결구의 몸체를 사출시키고자 시도된 바 있으나 이는 금형이 좌, 우로 이동되는 과정에서 자석에 부착된 체결 철선이 요홈에서 쉽게 이탈되어 양 금형의 결합시에 돌출된 체결 철선으로 손상되었을 뿐 아니라 많은 제품이 체결구 몸체에 체결 철선을 일체로 정확히 삽입 사출되지 않은 불량품으로 성형되어 나오므로 실용화될 수 없는 결점이 있었다.Conventionally, in order to manufacture the body of the fastener in which the fastening wire is integrally formed, grooves are formed in the upper part of the mold, and magnets are installed to attach the fastening wire to the magnet and combine both molds to inject the fastener body. This is because the fastening wire attached to the magnet was easily detached from the groove in the process of moving the mold to the left and right, and it was damaged by the fastening wire which protruded when the two molds were joined together. There was a defect that could not be put to practical use because it is molded into a defective product that is not inserted or injected.
본 고안은 이와 같은 종래의 결점을 해결하기 위하여 좌, 우로 이동되는 작동구에 요홈을 형성하여 요홈에 체결철선을 삽입 지지시키고 일측 금형에 형성된 괘지 돌부가 요홈에 삽입 지지된 체결 철선의 내측으로 삽입 고정되어 체결 철선이 요홈에서 견고하게 설치되어 있으므로 금형이 이동되어도 체결 철선이 움직이거나 어긋나지 않아 정확한 제품을 만들어 낼수 있을뿐 아니라 체결 철선을 요홈에 꽂기만 하면 괘지 돌부가 밀착 삽입되면서 체결 철선을 제 위치에 안착시키므로 체결구 몸체를 불량품없이 손쉽게 제조하기 위한 목적으로 안출된 것이다.The present invention forms a groove in the operating port to move to the left, right to solve the conventional drawbacks such as to insert and support the fastening wire in the groove and inserted into the inner side of the fastening wire wire is inserted into the groove formed by the protrusions formed in one mold Since the fastening wire is firmly installed in the groove, it is possible to produce the correct product because the fastening wire does not move or deviate even if the mold is moved. Since it is seated in the fastener body is devised for the purpose of easy manufacturing without defective parts.
이를 첨부도면에 따라 상세히 설명하면 다음과 같다. 금형(1)에 안착부(2)를 요설하여 안착부(2)에 지지부홈(3)(3')이 형성된 괘지돌부(4)(4')를 금형(1)과 일체로 형성하고 측벽부에 삽입공(5)(5')을 천공하며, 요홈(10)(10')과 구멍(8)(8')이 형성된 작동구(6)에 이동봉(7)(7')을 고정시켜 이동봉(7)(7')이 삽입공(5)(5')에 삽입 이동됨에 따라 작동구(6)가 좌, 우 이동되어 안착부(2)에 삽입 안착되고 작동구(6)가 좌, 우 이동됨에 따라 구멍(8)(8')으로 괘지 돌부(4)(4')가 삽탈되며 작동구(6)의 내측 하부로 형성된 요홈(10)(10')에 체결 철선(9)(9')을 삽입시키고 작동구(6)를 이동시켜 안착부(2)에 삽입 안착시키며 체결구 몸체(12)와 동일한 홈을 갖는 타측 금형(1')을 일측 금형(1)에 결합시켜 체결 철선(9)(9')이 지지부(11)가 일체로 구성된 체결구 몸체(12)를 사출시키는 구조이다.This will be described in detail with reference to the accompanying drawings. In the mold 1, the seating part 2 is formed, and the protrusions 4 and 4 ', in which the supporting part grooves 3 and 3' are formed in the seating part 2, are integrally formed with the mold 1 and the side wall is formed. Holes (5) and (5 ') are inserted into the holes, and the movable rods (7) and (7') are fixed to the operating holes (6) formed with grooves (10) (10 ') and holes (8) and (8'). As the moving rods 7 and 7 'are inserted into the insertion holes 5 and 5', the operating holes 6 are moved left and right to be inserted and seated in the seating part 2, and the operating holes 6 are As the left and right are moved, the fastening protrusions 4 and 4 'are inserted into the holes 8 and 8' and the fastening wires 9 are formed in the recesses 10 and 10 'formed in the inner lower part of the operating hole 6. (9 ') is inserted into the seating portion (2) by moving the actuator (6), and the other mold (1') having the same groove as the fastener body 12 is coupled to one mold (1) Fastening wires (9) (9 ') is a structure for injecting the fastener body 12, the support 11 is formed integrally.
미설명부호 13은 합성수지액 주입공이고, 14, 14' 는 금형을 금형 받침대에 고정시키는 체결공이다.Reference numeral 13 is a synthetic resin injection hole, 14, 14 'is a fastening hole for fixing the mold to the mold pedestal.
이상과 같이 구성된 본 고안의 금형(1)(1')은 유압으로 좌, 우 이동되는 금형 받침대에 고정되어 좌로 이동되며 체결 철선(9)(9')이 요홈(10)(10')에 삽입된 작동구(6)가 안착부(2)에 삽입 안착되면서 괘지돌부(4)(4')가 구멍(8)(8')에 삽입되어 요홈(10)(10')에 삽입된 체결 철선(9)(9')을 제1도에서와 같이 내측에서 견고하게 지지시키는 것이며 괘지돌부(4)(4')의 저부에 지지부홈(3)(3')이 형성되어 양측 금형(1)(1')을 결합시키고 합성수지액 주입공(13)으로 합성수지액을 주입하면 지지부홈(3)(3')에서 체결구 몸체(12)와 일체로 사출되는 지지부(11)가 성형됨과 동시에 지지부(11)에 체결 철선(9)(9')이 삽입 사출되는 것이다.Mold (1) (1 ') of the present invention configured as described above is fixed to the mold pedestal that is moved left and right by hydraulic movement to the left and the fastening wire (9) (9') to the groove (10) (10 ') The fastener inserted into the recess 8, 8 'is inserted into the hole (8) (8') while the inserted operation port (6) is inserted into the seating portion (2) The steel wires 9 and 9 'are firmly supported from the inside as shown in FIG. 1, and the support grooves 3 and 3' are formed at the bottom of the protrusion 4 and 4 'so that both molds 1 (1 ') and the synthetic resin solution injection into the synthetic resin injection hole 13, the support portion 11 which is integrally injected with the fastener body 12 in the support groove (3) (3') is molded and Fastening iron wires 9 and 9 'are inserted into the support part 11.
이와 같이 작동구(6)에 요홈(10)(10')을 형성하여 체결 철선(9)(9')이 삽입된 요홈(10)(10')으로 괘지 돌부(4)(4')가 밀착 삽입되면서 체결 철선(9)(9')이 이동되지 않게 제위치에 견고하게 지지시킴과 동시에 괘지 돌부(4)(4')의 저부에 지지부홈(3)(3')을 형성하여 견고하게 지지된 체결 철선(9)(9')이 제4도에서와 같이 지지부홈(3)(3')의 중앙으로 삽입되어 있으므로 제5도 및 제6도에서와 같이 개구부에 고정 설치하는 체결구를 불량품없이 제조할 수 있는 것이며 체결 철선(9)(9')이 금형(1)(1')에 이탈됨이 없이 견고하게 협지되어 체결 철선(9)(9')이 금형(1)(1')을 손상시킬 염려없이 간편하게 제조할 수 있는 효과가 있는 것이다.In this way, the grooves 10 and 10 'are formed in the grooves 10 and 10' in which the grooves 10 and 10 'are formed in the operating hole 6, so that the hanging protrusions 4 and 4' are inserted into the grooves 10 and 10 '. While tightly inserted, the fastening wires 9 and 9 'are firmly held in place so that they are not moved, and at the same time, the support grooves 3 and 3' are formed at the bottom of the hanging protrusions 4 and 4 '. Fastened steel wires 9 and 9 'are inserted into the center of the support grooves 3 and 3' as shown in FIG. The spheres can be manufactured without defective products and the fastening wires 9, 9 'are firmly clamped without leaving the mold 1, 1' so that the fastening wires 9, 9 'can be There is an effect that can be easily produced without fear of damaging (1 ').
