The horizontal surface 34b is a member for interviewing with the position fixing block 40 when the core C is mated to determine and fix the protruding position of the insert core 10. When the inclined cam 34 is horizontally transferred as shown in FIG. The two inclined surfaces 43a and the cam holes 32 are slid to form the cavity space with the insert core 10 protruding, and at this time, the horizontal surface 34b is supported as being interviewed by the position fixing block 40. The play of the insert core 10 by external force is prevented and the insert core 10 is always fixed at a fixed position when the molded product A is repeatedly molded, thereby preventing molding defects of the molded product A due to a misalignment position error. .

그리고, 위치고정블록(40)이 코어(C)와 분할제작되어 볼트를 포함한 체결부재에 의해 탈부착되도록 설치됨에 따라 반복사용으로 인한 위치고정블록(40) 혹은 수평면(34b)의 마모로 인서트코어(10)의 형합위치가 가변시 위치고정블록(40)을 교체하면 간편하게 보정된다. And, since the position fixing block 40 is divided into the core (C) and installed to be detached by a fastening member including a bolt, the insert core (40) due to wear of the position fixing block 40 or the horizontal surface 34b due to repeated use. 10) When the matching position is variable, simply replace the position fixing block 40 is corrected.

작동상에 있어서, 코어(C)가 형합되어 캐비티 공간을 형성시 경사캠(34)이 수평운동하여 제2경사면(34a)과 캠홀(32)의 경사운동에 의해 인서트코어(10)가 캐비티공간에 긴밀하게 조립되고, 이어서 용융상태의 성형재료를 캐비티공간에 주입하여 경화 혹은 고화된 후 취출시, 먼저 경사캠(34)이 수평운동하면 제2경사면(34a)이 캠홀(32)과 경사운동되어 인서트코어(10)가 후퇴하되, 이때 인서트코어(10)는 가이드블록(22)과 가이드홈(24)에 의해 대각선방향으로 이송방향이 안내 되어 제1경사면(12)을 타고 성형품상에서 이격된 다음 코어(C)가 형개된다.In operation, when the core C is joined to form a cavity space, the inclined cam 34 is horizontally moved, and the insert core 10 is inclined by the inclined motion of the second inclined surface 34a and the cam hole 32. When the inclined cam 34 is horizontally moved, the second inclined surface 34a is inclined with the cam hole 32 when the molded material in a molten state is hardened or solidified by being injected into the cavity space. Insert core 10 is retracted, but the insert core 10 is guided in a diagonal direction by the guide block 22 and the guide groove 24 to be spaced apart on the molded part on the first inclined surface 12 Next, the core C is opened.

이처럼, 성형품(C) 취출단계에서 무구배부분에 대응하는 인서트코어(10)가 형개전에 먼저 후퇴작동됨에 따라 코어(C)와 성형품(A)의 마찰로 인한 긁힘불량이 방지된다.
