본 고안은 체결부재의 고정위치 결정용으로 사용되는 맞춤핀을 분리하기 위한 맞춤핀 분리용 간이치구에 관한 것으로, 특히 걸림편을 상.하단부에 구비한 봉상몸체의 중간부에 격타구를 상.하 이동가능하게 삽입한 간이치구를 형성하고 그 간이치구의 하측 걸림편에는 맞춤핀의 상측부에 형성한 암나사부에 체결되는 고정나사를 고정하여 맞춤핀의 분리작업을 간편 용이하게 할 수 있게한 맞춤핀 분리용 간이치구에 관한 것이다.The present invention relates to a simple pin for detaching the alignment pin for separating the alignment pin used for fixing the fastening position of the fastening member, in particular, the engaging piece in the middle of the rod-shaped body provided with the upper and lower ends. Forming a simple jig inserted into the lower movable form and fixing the fastening screw fastened to the female screw formed on the upper side of the dowel pin on the lower engaging piece of the simple jig to facilitate the separation operation of the dowel pin. It relates to a simple fixture for separating dowel pins.
일반적으로 프레스금형에서 핀치다이를 다이홀더에 고정하거나 사출금형에서 캐비티가 형성된 형판을 형판홀더에 고정하는 경우에는 2개판의 고정위치를 정확하게 확보할 수 있는 고정구조가 요구되는 바, 이와 같은 고정구조는 제3도에 도시한 바와 같이 2개의 부재(1),(2)(이하 상.하부재(1),(2)로 기재함)에 수개의 위치결정공(1a)(2a)을 관통되게 천공하여 그 위치결정공(1a)(2a)에 맞춤핀(3)을 끼워 맞추는 구조로 되어 있으며, 필요에 따라 상.하부재(1)(2)를 분리하고자 하는 경우에는 상기 위치결정공(1a)(2a)보다 적은직경을 가지는 환봉상 분리핀을 상기 맞춤핀(3)의 단부에 일치시킨 상태에서 망치등으로 격타하여 맞춤핀(3)을 위치결정공(1a) (2a)으로부터 분리시킴으로써 상.하부재(1)(2)를 분리하였으므로 분리작업이 불편한 결함이 있으며, 이와 같은 고정구조는 대형금형에서 하측부재의 두께가 두꺼워서 하측부재에 형성하는 위치결정공을 관통시켜 천공하지 못하는 경우에는 맞춤핀(3)을 상기한 바와 같이 분리수단으로 분리하기가 불가능하게 되므로 하측부재의 하면을 망치등으로 두드려 분리시키고 있는 실정이다.In general, when a pinch die is fixed to a die holder in a press mold or a template in which a cavity is formed in an injection mold is fixed to a template holder, a fixing structure for precisely securing a fixed position of two plates is required. As shown in FIG. 3, the plurality of positioning holes 1a and 2a penetrate through the two members 1 and 2 (hereinafter, referred to as upper and lower members 1 and 2). It is designed to fit the positioning pins (3) to the positioning holes (1a) and (2a), and if necessary to separate the upper and lower members (1) and (2), the positioning holes (1a) (1a) (2a) round bar-shaped separating pin having a diameter smaller than the end of the dowel pin (3) with a hammer or the like to beat the dowel pin (3) from the positioning hole (1a) (2a) Since the upper and lower members (1) and (2) are separated by the separation, there is a defect that the separation operation is inconvenient. In the case of the large mold, when the lower member is thick and cannot penetrate through the positioning hole formed in the lower member, the jaw pin 3 cannot be separated by the separating means as described above. The situation is being beaten with a hammer.
그러나, 이와 같은 분리방법은 맞춤핀 분리작업이 매우번거롭고 까다로울 뿐아니라, 대형금형에서는 맞춤핀이 쉽게빠지지 않게되어 제품의 생산에 지장을 초래하게 되는 문제점이 있었다.However, such a separation method is not only very cumbersome and difficult to remove the dowel pin, but in the large mold, there is a problem that the dowel pin does not easily fall out, which causes a problem in the production of the product.
본 고안은 이와 같은 종래의 결함을 해소하기 위하여 안출한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to solve such a conventional defect, described in detail by the accompanying drawings as follows.
제1도 및 제2도에 도시한 바와 같이 상측단부에 걸림편(4a)을 일체로 형성한 간이치구의 봉상몸체(4) 중간부에 그 몸체(4)의 외경보다 큰 내경의 삽입공(5a)를 가지는 격타구(5)를 삽입하고 간이치구의 몸체(4) 하단부에는 걸림편(4a')을 용접등으로 고정하여 상기 격타구(5)가 봉상몸체(4)의 중간부 즉, 상.하부 걸림편(4a) (4a')의 사이에서 상.하로 자유로이 이동할 수 있게하고, 하측 걸림편(4a')의 중간부에는 암나사부(4b)를 형성하여 그 암나사부(4b)에는 일정길이를 가지는 나사(6)의 상측부를 나사맞춤으로 고정하고 그 나사(6)의 하측부에는 상.하부재(1)(2)의 고정위치 결정용 맞춤핀(3)의 상측부에 형성된 암나사부(3a)에 체결되는 수나사부 (6a)를 형성한 것으로, 도면중 미설명부호 5b는 격타구(5)의 외주면에 만곡형으로 형성한 손잡이부를 보인 것이고, 6b는 상기 나사(6)를 스패너등의 공구로 간이치구의 걸림편(4a')에 결합하고 분리하기 위하여 그 나사(6)의 중간부에 형성한 스패너 물림부를 보인 것이다.As shown in FIGS. 1 and 2, an insertion hole having an inner diameter larger than the outer diameter of the body 4 in the middle portion of the rod-shaped body 4 of the simplified tooth in which the locking piece 4a is integrally formed at the upper end ( Inserting the batter 5 having the 5a) and fixing the locking piece 4a 'to the lower end of the body 4 of the simplified tooth by welding or the like, so that the batter 5 is an intermediate part of the rod-shaped body 4, It is possible to move freely up and down between the upper and lower locking pieces 4a and 4a ', and a female threaded portion 4b is formed in the middle of the lower locking piece 4a' and the female threaded portion 4b The upper part of the screw 6 having a predetermined length is fixed by screwing, and the lower part of the screw 6 is formed on the upper part of the fixing pins 3 for fixing the upper and lower members 1 and 2. A male screw portion 6a fastened to the female screw portion 3a is formed. In the drawing, reference numeral 5b shows a handle portion formed in a curved shape on the outer circumferential surface of the batter 5, and 6b is an upper portion. To couple with the screw 6, clamping members (4a ') of the simple jig in a tool such as a wrench and remove the wrench engagement section is shown formed in a middle part of the screw (6).
이하 같이된 본 고안의 작용효과는 다음과 같다.The effect of the present invention as follows is as follows.
상.하부재(1)(2)에서 맞춤핀(3)을 분리하고자 하는 경우에는 맞춤핀(3)의 암나사부(3a)에 간이치구에 하측 걸림편(4a')에 고정된 나사(6)의 하측 수나사부(6a)를 체결시킨 후 격타구(5)의 파지부(5b)를 잡고 그 격타구(5)로 간이치구의 상측 걸림편(4a)을 수회 격타하게되면 그 격타력에 의하여 맞춤핀(3)이 점차로 분리되어진다.When the alignment pins 3 are to be separated from the upper and lower members 1 and 2, the screws 6 fixed to the lower locking pieces 4a 'to the female threaded portions 3a of the alignment pins 3 are inserted into the simplified teeth. After tightening the lower male thread portion 6a of the bottom), grab the holding portion 5b of the batter 5, and the batter 5 hits the upper locking piece 4a of the simplified gear several times. By the dowel pin 3 is gradually separated.
한편, 사용중에 간이치구의 하측 걸림편(4a')에 결합되어 있는 나사(6)을 교환할 필요가 있는 경우에는 나사(6)의 중간물림부(6b)를 이용하여 스패너등의 공구로 간단히 교환할 수 있다.On the other hand, when it is necessary to replace the screw 6 coupled to the lower engaging piece 4a 'of the simplified fixture during use, simply use a tool such as a spanner by using the intermediate grip portion 6b of the screw 6. I can exchange it.
이상에서 설명한 바와 같은 본 고안은 상.하 걸림편을 구비한 봉상몸체에 격타구가 삽입되는 간이치구를 형성하고 그 간이치구의 하측 걸림편에는 상.하부재 고정위치 결정용 맞춤핀의 상측부에 형성한 암나사부에 체결되는 나사를 고정한 간단한 구성에 의하여 맞춤핀을 간편 용이하게 분리할 수 있는 이점이 있다.The present invention as described above forms a simplified tooth in which a batter is inserted into a rod-shaped body having upper and lower locking pieces, and an upper portion of an upper and lower member fixing pin for positioning the upper and lower members on the lower locking piece of the simplified tooth. By the simple configuration of fixing the screw fastened to the female thread formed in the advantage that there is an advantage that can be easily separated.
