Description

금형코어유닛의 가이드블럭 {Core unit guide block} Mold core unit guide block {Core unit guide block}

본 발명은 금형코어유닛의 가이드블럭에 관한 것으로, 보다 상세하게는 플라스틱 금형의 이젝터핀을 지지하는 금형코어유닛의 구성을 단순화하면서 볼부시를 보다 간편하게 조립하여 경사핀을 안정적으로 지지할 수 있도록 발명한 것이다.The present invention relates to a guide block for a mold core unit, and more particularly, to simplify the configuration of a mold core unit supporting an ejector pin of a plastic mold while assembling a ball bush more easily to stably support an inclined pin did it

일반적으로, 플라스틱 금형에서 성형이 완료된 제품을 금형으로부터 이젝팅시키기기 위해 사용되는 이젝트핀을 지지하는 종래의 금형코어유닛은 도 1에 도시된 바와 같이 하금형(M)에 출몰가능하게 결합되는 코어(109)와, 선단이 코어(109)에 결합되고 하단이 하고정판(104)에 고정된 회동블록(105)에 결합되는 경사핀(!02)과, 이 경사핀(102)이 슬라이드가능하게 관통되며 상기 하금형(M)의 저면에 결합되는 상부가이드블록(101)과, 경사핀(102)이 관통된는 하원판부재(103)에 장착되는 하부가이드블록(106)을 포함한다.In general, a conventional mold core unit supporting an ejection pin used to eject a molded product from a mold in a plastic mold is a core that is retractably coupled to the lower mold M as shown in FIG. 1 . (109), a tip end coupled to the core 109 and a lower end coupled to a rotation block 105 fixed to a fixed plate 104, an inclined pin (!02), and the inclined pin 102 to be slidable It includes an upper guide block 101 that is penetrated and coupled to the bottom surface of the lower mold M, and a lower guide block 106 that is mounted on the lower plate member 103 through which the inclined pin 102 is penetrated.

상기 가이드블록(101,106)은 도 2에 도시된 바와 같이 가운데 경사핀(102)이 관통되는 축공(112)이 형성된 볼부시(107)와, 이 볼부시(107)가 삽입되어 지지되는 수납홈(112)이 형성된 부시바디(108)로 구성된다.As shown in FIG. 2, the guide blocks 101 and 106 include a ball bush 107 having a shaft hole 112 through which the inclined pin 102 passes, and a receiving groove into which the ball bush 107 is inserted and supported. 112) is composed of a formed bush body (108).

그런데, 선행된 금형코어유닛의 가이드블록(101,106)은 일체로 제작된 부시바디(108)에 구체인 볼부시(107)를 끼워서 지지하기 위해서는 대략 구형상의 수납홈(112)에 장방형의 절개홈을 형성하고, 볼부시(107)도 이에 대응하도록 그 양측면을 절취하여 절취면(114)을 형성한 후에 상기 절취면(114)이 장방형홈(113)의 장변부와 정렬되도록 끼운 후에 90도 회전시켜서 볼부시(107)가 수납홈(112)에서 회전가능하게 구속되도록 결합하게 된다.However, in order to support the guide blocks 101 and 106 of the mold core unit in advance by inserting the ball bush 107, which is a sphere, into the bush body 108 manufactured integrally, a rectangular incision groove is formed in the receiving groove 112 of a substantially spherical shape. The ball bush 107 is also cut out on both sides to form a cut-out surface 114, and then the cut-out surface 114 is inserted so as to be aligned with the long side of the rectangular groove 113, and then rotated 90 degrees. The ball bush 107 is coupled to be rotatably constrained in the receiving groove 112 .

그러나, 상기의 가이드블록(101,106)은, 부시바디(108)의 수납홈(112)과 볼부시(107)가 공히 절취되어 결합되므로, 부시바디(108)와 볼부시(107)의 접촉 또는 지지면적이 상대적으로 작으므로, 부시바디(108)가 볼부시(107)를 견고하고 안정되게 지지할 수 없는 문제점이 있었다.However, in the guide blocks 101 and 106 , the receiving groove 112 and the ball bush 107 of the bush body 108 are both cut and coupled, so that the bush body 108 and the ball bush 107 are in contact or support. Since the area is relatively small, there is a problem that the bush body 108 cannot firmly and stably support the ball bush 107.

또, 상기와 같이 볼부시(107)가 안정되지 않은 상태에서는 동작 중에 미세한 진동이 발생하게 되고, 이에 따라 경사핀(102)도 볼부시(107)를 통해 원활하게 안내되지 못하여 부하가 커지고 결과적으로 제품의 수명이 단축되는 문제점이 있었다.In addition, in a state in which the ball bush 107 is not stable as described above, minute vibration is generated during operation, and accordingly, the inclined pin 102 is also not smoothly guided through the ball bush 107, resulting in a large load. There was a problem in that the life of the product was shortened.
