본 고안은 분말야금용 금형의 받침판에 관한 것으로, 특히 금형의 조립 및 세척이 용이하고, 금형의 분해/조립시간 단축 및 금형의 정도(精度)를 향상시킬 수 있도록 받침판의 구조를 개량한 것이다.The present invention relates to a support plate of a powder metallurgy mold, and in particular, the structure of the support plate is improved to facilitate the assembly and cleaning of the mold, to shorten the disassembly / assembly time of the mold and to improve the precision of the mold.

종래에는 분말야금용 금형을 지지하도록 된 받침판을 제4도내지 제5도에 나타낸 바와 같이 각 받침판(100)들의 상면에 등간격으로 배열되는 체결공(200)들과 조립공(300)들을 형성하고 이들에 각각의 나사탭을 형성하며 상기 각각의 체결공(200)들과 상,하로 관통되는 조립공(300)들의 중심이 일치하도록 받침판(100)들을 상,하로 적층시킨 다음, 받침판(100)의 조립공(300)으로 관통되게 끼워지는 각각의 체결부재(400)의 끝단을 체결공(200)에 나사 결합시킴에 따라 제5도와 같이 필요한 길이로 금형 받침판을 구성하도록 되어 있었다.Conventionally, as shown in FIGS. 4 to 5, the support plates 200 supporting the powder metallurgical mold are formed with fastening holes 200 and assembly holes 300 arranged at equal intervals on the upper surfaces of the support plates 100. Forming the thread tabs thereon and the base plate 100 is stacked up and down so that the centers of the assembly holes 300 penetrated up and down with the respective fastening holes 200, and then, the base plate 100 As the end of each fastening member 400 inserted through the assembly hole 300 is screwed into the fastening hole 200, the mold support plate is configured to have a required length as shown in FIG. 5.

또, 상기 받침판(100)들의 조립공(300)에는 받침판(100)을 체결하는 체결부재(400)의 헤드(401)가 수용될 수 있도록 조립공(300)의 직경보다 넓게 형성되는 카운터 보어(301)를 형성하여 받침판(100)의 상면으로 체결부재(400)가 돌출되지 않고 그 내측으로 수용될 수 있도록 함으로써 받침판의 상,하조립이 가능하도록 구성되어 있었다.In addition, the counter bore 301 is formed in a wider than the diameter of the assembly hole 300 to accommodate the head 401 of the fastening member 400 for fastening the base plate 100 in the assembly hole 300 of the support plate 100. Formed to enable the fastening member 400 to be accommodated inwardly without protruding to the upper surface of the support plate 100 was configured to enable the top, bottom assembly of the support plate.

그러나, 상기와 같은 종래의 것은 제4도(a)와 같이 받침판(100)의 조립공(300)에 체결부재(400)의 헤드(401)를 수용하는 카운터 보어(301)의 길이가 짧을 경우에는 상대적으로 체결부재(400)의 길이가 길어져 불안정한 구조를 이루게 되었으며, 제4도(b)와 같이 카운터 보어(301)의 깊이를 깊게 가공할 경우에는 체결부재(400)의 길이가 짧아지는 이점이 있으나, 제4도(b)와 같이 카운터 보어(301)의 길이를 깊게 형성할 경우 작업중 분말이나 기름과 같은 이물질이 체결부재(400)가 끼워진 카운터 보어(301)에 들어가게 되어 이를 제거하는데 많은 어려움이 있어 받침판의 분해/조립시간이 많이 소요되는 문제점이 있었다.However, when the counterbore 301 for receiving the head 401 of the fastening member 400 in the assembly hole 300 of the support plate 100 is short as shown in FIG. The length of the fastening member 400 is relatively long to form an unstable structure. When the depth of the counterbore 301 is deeply processed as shown in FIG. 4 (b), the length of the fastening member 400 is shortened. However, when the length of the counterbore 301 is deeply formed as shown in FIG. 4 (b), foreign matter such as powder or oil enters the counterbore 301 into which the fastening member 400 is inserted during operation, and thus it is difficult to remove it. There was a problem that takes a lot of disassembly / assembly time of the support plate.

이러한 종래의 문제점은 체결부재가 끼워지는 조립공을 받침판의 상,하부로 관통되는 비교적 작고 긴 구멍으로 형성함으로써 그 내측으로 불순물이 유입되더라도 이를 쉽게 제거할 수 없는데 비롯된 것이다.This conventional problem is caused by the formation of a relatively small and long hole penetrating the upper and lower portions of the support plate into which the fastening member is fitted, even if impurities are introduced into the inside thereof.

본 고안은 상기와 같은 종래의 제결점을 해소하기 위해 분말야금용 금형을 지지하는 받침판을 형성함에 있어서, 체결부재가 관통되면서 끼워지는 조립공의 상부측을 축방향으로 길게 절삭하여 형성하고 받침판의 일측면과 서로 통하도록 되는 요부를 형성하며 조립공에 관통되게 끼워지는 체결부재의 길이를 짧게 형성하고 작업중 체결부재의 상면으로 이물질 등이 쌓이더라도 받침판의 일측면에서 이를 용이하게 제거할 수 있도록 구성한 것인바, 이를 첨부된 예시도면을 참고하여 설명하면 다음과 같다.The present invention is formed by cutting the upper side of the assembly hole to be inserted while the fastening member is penetrated while forming the support plate for supporting the powder metallurgy mold in order to solve the conventional defects as described above and the work of the support plate It is formed to form a recess to communicate with each other and to shorten the length of the fastening member to be inserted through the assembly hole and to easily remove it from one side of the support plate even if foreign matters accumulate on the upper surface of the fastening member during operation. This will be described below with reference to the accompanying drawings.

제1도는 본 고안에 따른 받침판의 구성을 나타내고 있는 예시도이다.1 is an exemplary view showing the configuration of the support plate according to the present invention.

받침판(1)의 조립을 위해 나사탭이 구비되는 다수개의 체결공(2,2,..)을 일정한 간격으로 형성하고, 상기 체결공(2,2,..) 사이사이에 상부측으로부터 하부측으로 일정한 깊이만큼 축방향으로 길게 절삭되어 형성되는 요부(3)를 형성하며 상기 요부(3)의 내측에 체결부재(4)가 끼워지는 조립공(5)을 설치하여 구성된 것이다.Form a plurality of fastening holes (2, 2, ..) provided with screw tabs at regular intervals for assembling the support plate (1), and between the fastening holes (2, 2, ...) from the top side to the bottom It forms a recessed portion (3) is formed by cutting in the axial direction by a certain depth to the side and is configured to install an assembly hole (5) in which the fastening member (4) is fitted inside the recessed portion (3).

이상과 같이 구성된 본 고안은 종래와 동일하게 상,하로 적층되게 조립하고자하는 받침판(1)(1)의 체결공(2,2,..)과 조립공(5,5,..)의 중심이 일치하도록 받침판(1,1)을 상,하로 적층시킨 다음, 받침판(1)의 조립공(5)으로 각각의 체결부재(4)를 끼워 체결공(2)에 나사 결합시킴에 따라 제2도와 같이 필요한 길이로 되는 금형 받침판을 구성할 수 있는 것이다.The present invention configured as described above is the center of the fastening hole (2, 2, ..) and the assembly hole (5, 5, ...) of the support plate (1) (1) to be assembled to be stacked up and down as in the prior art Lay up and down the support plates 1 and 1 so as to coincide with each other, and then insert the respective fastening members 4 into the assembly holes 5 of the support plates 1 and screw them into the fastening holes 2 as shown in FIG. It is possible to construct a mold base plate having a required length.

제3도는 본 고안과 서로 다른 형태를 이루는 받침판의 다른 실시예를 나타낸 것으로써, 받침판(6)의 몸체를 중공체로 형성하고, 각각의 체결공(61,61,..)이 형성되는 사이사이에 일정한 깊이만큼 절삭하여 형성되는 요부(62,62,..)를 등간격으로 배치하며 상기 요부(62,62,..)에 체결부재(4)가 끼워지는 조립공(63,63,..)을 구비하여 받침판(6)을 구성할 수 있는 것이다.Figure 3 shows another embodiment of the support plate to form a different form from the present invention, the body of the support plate 6 is formed between the hollow body, and each of the fastening holes (61, 61, ...) is formed between Recesses 62, 62, .. formed by cutting to a predetermined depth at equal intervals, and assembly holes 63, 63, .. which fastening member 4 is fitted to the recesses 62, 62,. ), The supporting plate 6 can be configured.

이와 같이 본 고안은 종래와 같이 체결부재의 헤드가 끼워지는 카운터 보어를 형성하는 대신 받침대의 상부측으로부터 하부측으로 일정한 깊이만큼 절삭되는 요부를 형성하여 상기 요부에 체결부재가 끼워지는 조립공을 설치함으로써 상,하 받침판을 체결하는 체결부재의 길이가 짧아지는 이점이 있고, 작업중 요부를 통해 체결부재의 상면으로 분말이나 기름과 같은 이물질 등이 쌓이더라도 받침판의 일측면을 통해 이를 긁어낼 수 있게 되므로 이물질의 제거 및 세척이 아주 간편하게 이루어지게 된다.As described above, the present invention forms a recess that is cut by a predetermined depth from the upper side to the lower side of the pedestal instead of forming a counterbore into which the head of the fastening member is fitted, thereby providing an assembly hole into which the fastening member is fitted. The length of the fastening member for fastening the lower support plate is shortened, and even if foreign matter such as powder or oil accumulates on the upper surface of the fastening member through the main part, it is possible to scrape it out through one side of the support plate. Removal and cleaning are very easy.

또한, 받침판을 조립하는 체결부재의 진입이 측면을 통해서도 가능하기 때문에 작업이 용이하고,작업자가 직접 조립상태를 확인할 수 있어 금형 조립의 정밀도가 향상됨은 물론, 조립 및 분해가 신속하게 이루어지는 이점이 있다.In addition, since the entry of the fastening member for assembling the support plate is possible through the side, it is easy to work, and the operator can check the assembly state directly, thereby improving the precision of the mold assembly and having the advantage of quick assembly and disassembly. .
