본고안은 사출금형에서 어퍼 하우징(Uper Hoysubg)과 같이 다수의 긴 경사보스를 갖는 제품의 경사보스 처리장치에 관한것로서, 특히 사출금형의 가동측 중심에 다수의 경사 코어핀을 갖는 이젝트 플레이트(Eject Plate)를 경사지게 설치하고 이 양단에 유압 실린더를 설치하여, 상기 제품을 성형한 후 제품을 취출시키기전에 유압 실린더를 작동시켜 손쉽고 간편하면서 간단한 구조를 제품의 경사보스를 처리하여 줄 수 있도록 한 유압 실린더를 이용한 사출금형의 경사보스 처리장치에 관한 것이다.The present invention relates to an inclined boss processing apparatus for a product having a plurality of long inclined bosses such as an upper housing (Uper Hoysubg) in an injection mold, and in particular, an eject plate having a plurality of inclined core pins at the center of the movable side of the injection mold ( Hydraulic plate installed at an inclined side and hydraulic cylinders are installed at both ends, and the hydraulic cylinder is operated after molding the product before the product is ejected, so that the easy and simple and simple structure can be processed by the inclined boss of the product. The present invention relates to an inclined boss processing apparatus of an injection mold using a cylinder.
일반적으로 어퍼 하우징과 같이 다수의 긴 경사보스를 갖는 제품을 성형하기 위해서는 제품성형후 금형을 이형 시키기전 상기 경사보스부를 먼저 이젝트시켜 처리해 주는 장치가 필요했던 것이다.In general, in order to mold products having a plurality of long inclined bosses such as upper housings, an apparatus for ejecting and treating the inclined bosses first before forming a mold after forming a product is required.
상기와 같은 목적으로 종래에는 다수의 경사보스부를 처리하여주는 코어핀을 개별적으로 설치하여 슬라이드편으로서 작동시켜 이형전이나 이형과 동시에 경사보스부를 처리하여 줄 수 있게 하였으나 이는 다수의 경사보스부를 처리하기 위해서 설치되는 코어핀을 슬라이드편으로서 동작시키기 때문에 금형이 필요이상으로 커질 뿐아니라 코어자체가 경사지게 설치되어야 하므로 금형제작의 어려움이 많았다.Conventionally, for this purpose, the core pins for treating a plurality of inclined bosses are individually installed to operate as slide pieces, so that the inclined bosses can be treated simultaneously with or before release, but this is to handle a plurality of inclined bosses. In order to operate the core pin to be installed as a slide piece, the mold was not only larger than necessary, but also the core itself had to be inclined so that it was difficult to manufacture the mold.
따라서 작업성 즉 성형사이클이 길어져 작업능률 저하로 생산성이 떨어 질 뿐아니라, 금형제작비가 많이 소모되어 비경제적이었고 특히 금형 자체가 중량화되고 부피가 커서 더욱 작업상 인력과 시간의 손실이 많아 제품의 제조단가가 상승되는 문제점이 있었다.As a result, the workability, that is, the molding cycle is long, not only decreases productivity due to lower work efficiency, but also it is uneconomical because the mold manufacturing cost is consumed a lot. There was a problem that the manufacturing cost is increased.
본고안은 상기와 같은 종래의 제반 문제점을 보완하고져 사출금형의 가동측 중심에 다수의 경사코어핀과 코어붓싱이 설치되는 하나의 이젝트 플레이트를 설치하고, 이 양단에 유압 실린더를 설치하여 제품 성형후 금형의 이형전에 유압 실린더가 작동하여 다수의 코어핀을 동시에 취출시켜 제품의 경사보스를 처리할 수 있게 한 것으로서, 이하 본고안을 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.This paper solves all the above-mentioned problems and installs a single ejection plate on which a plurality of inclined core pins and core bushings are installed at the center of the movable side of the injection mold. The hydraulic cylinder is operated before the mold is released, and a plurality of core pins are simultaneously taken out to process the inclined bosses of the product. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본고안의 구성를 보면 제1도와 제2도에서 보는 바와 같이 통상적으로 고정측 설치판(2)과 고정측 형판(3) 및 가동측 성형코어(4)와 가동측 형판(5) 그리고 가동측 설치판(6)으로 구성되는 사출금형(1)에 있어서, 상기 사출금형(1)의 가동측 형판(5)하측으로 다수의 경사 코어핀(7)과 코어 붓싱(8)이 설치되는 이젝트 플레이트(9)를 설치하고, 이 양단에 유압 실린더(10)를 설치하여 상기 경사 코어핀(7)과 코어붓싱(8) 및 이젝트 플레이트(9)가 유압실린더(10)에 의해서 한번에 이동 동작하면서 제품(P)의 경사보스부를 처리하여 줄 수 있게 구성된 것이다.In this configuration, as shown in Figs. 1 and 2, the fixed side mounting plate 2, the fixed side template 3, the movable side forming core 4, the movable side template 5, and the movable side mounting plate are shown. In the injection mold (1) consisting of (6), the eject plate (9) in which a plurality of inclined core pins (7) and core bushings (8) are provided below the movable side template (5) of the injection mold (1). And a hydraulic cylinder (10) at both ends thereof so that the inclined core pin (7), the core bushing (8), and the eject plate (9) are moved by the hydraulic cylinder (10) at once. It is configured to process the inclined boss of).
상기와 같이 구성된 본고안의 작용효과를 설명하면 다음과 같다 먼저 금형(1)내에 용융수지를 주입시켜 제품(P)를 취출시키기 위하여 금형(1)을 이형 시키기전 먼저 유압 실린더(10)를 작동시켜 이젝트 플레이트(9)를 작동시켜 주면 제 3도에서 보는바와 같이 이에 고정설치 되어 있는 성형 코어핀(7)과 코어붓싱(8)이 함께 작동하여 제품(P)을 취출시켜 줄 수 있게 되는 것이다.Referring to the effect of the present invention configured as described above as follows First, before releasing the mold (1) in order to take out the product (P) by injecting molten resin into the mold (1) by operating the hydraulic cylinder (10) When the eject plate 9 is operated, as shown in FIG. 3, the molded core pin 7 and the core bushing 8, which are fixedly installed thereon, work together to extract the product P.
이상에서 설명한 바와같이 사출금형에서 제품을 성형완료한후 제품의 경사보스부를 유압 실린더의 작동에 의해서 성형코어핀과 코어 붓싱이 빠지면서 동시에 다수의 경사보스를 처리하여 주게되므로 제품의 성형사이클이 종래보다 짧아져 생산능률과 생산성이 극대화 될 뿐 아니라 간단한 구조로서 다수의 경사보스를 한번에 처리하게 되므로 금형의 중량을 경량화 시키고 부피도 줄여 작업시 인력과 시간의 낭비를 줄일 수 있고, 특히 금형구조의 간소화로 제작비를 줄여 경제적인 효과와 제조단가를 절감 시킬 수 있는 효과를 얻고자한 것이다.As described above, after the product is molded in the injection mold, the inclined boss part of the product is processed by the hydraulic cylinder to remove the molding core pin and core bushing and simultaneously process a large number of inclined bosses. As it is shortened, the production efficiency and productivity are maximized, and as a simple structure, a large number of inclined bosses are processed at one time, thereby reducing the weight of the mold and reducing the volume, thus reducing the waste of manpower and time during work, and in particular, by simplifying the mold structure. It is intended to obtain the effect of reducing the manufacturing cost and economic effect and manufacturing cost.
