Abstract

PURPOSE: A vent apparatus of a curing metal mold is provided to prevent leakage of rubber, to improve air venting, to repair the vent apparatus easily and to prevent operating failure by improving the vent apparatus installed to the curing metal mold. CONSTITUTION: A funnel-shaped air inlet(20) is formed to an upper portion of an outer shell body(2). A guide groove(22) is formed to an inner edge of a through hole(21). A spring support(23) is formed to a lower portion of the through hole. An upper body(10) of a valve body(4) installed inside the outer shell is formed to correspond to a shape of the air inlet. A guide(42) is formed to a body(41) to be guided by being inserted to the guide groove. A groove(43) is formed to a lower side of the body to insert a spring(3). A movement of the valve body is minimized by forming the spring support in a different line of the guide groove. Thereby, air between a green tire and a metal mold is exhausted out of the metal mold through a gap between the air inlet and the upper body when the green tire is expanded by the bladder. The spring is compressed by pushing the upper body with the green tire. Therein, the air outlet is blocked to prevent rubber of the green tire from flowing into the air inlet.

Description

가류금형용 벤트장치{Ventilation apparatus for vulcanizing mold}Venting apparatus for vulcanizing mold

본 발명은 타이어의 가류공정시 그린 타이어와 금형의 사이에 존재하는 공기를 외부로 배출시킬 수 있도록 하는 벤트장치에 관한 것으로, 더욱 상세하게는 고무의 식출을 방지하면서도 공기 배출 능력을 증대시켜 완성된 타이어의 품위를 향상시킬 수 있게 하고, 벤트장치의 유지보수를 용이하게 하며, 작동불량을 방지할 수 있게 한 가류금형용 벤트장치에 관한 것이다.The present invention relates to a vent device that allows the air present between the green tire and the mold to be discharged to the outside during the vulcanization process of the tire, and more particularly, to prevent the extraction of rubber and to increase the air discharge capacity. The present invention relates to a venting device for a vulcanization mold that enables to improve the quality of a tire, facilitates maintenance of the venting device, and prevents malfunction.

일반적으로 생고무 상태로 제조되는 그린 타이어는 고온 고압의 가류금형 내에서 가류되어 완성된 타이어가 되며, 가류금형은 금형부와 그린 타이어를 금형에 가압시키는 브라더로 구성되고 금형의 내측면에는 그린 타이어와 금형과의 사이에 존재하는 공기를 금형 외부로 배출시킬 수 있게 하는 벤트홀을 설치되어 구성된다.In general, the green tires manufactured in a raw rubber state are vulcanized in a vulcanization mold of high temperature and high pressure. The vulcanization mold is composed of a mold part and a brother for pressing the green tire to the mold. Vent holes are provided to allow the air existing between the mold and the mold to be discharged to the outside of the mold.

이와 같은 벤트홀은 공기만을 배출시키는 것이 아니라 가류압력에 의해 그린 타이어의 고무가 벤트홀을 따라 함께 배출되어 완성된 타이어의 표면에 벤트러버를 형성시켜 완성된 타이어는 벤트러버를 제거하는 트리밍 공정을 필히 거쳐야만 되는 것이다.This vent hole not only discharges air but also the rubber of the green tire is discharged along the vent hole by the vulcanization pressure to form a vent rubber on the surface of the finished tire, and the finished tire has a trimming process of removing the vent rubber. It must go through.

이와 같은 문제점을 해결하기 위하여 종래에도 다양한 벤트장치가 제공된바 있다.In order to solve this problem, various vent devices have been provided in the related art.

However, such a conventional venting device can not only form the diameter of the valve body to a significantly smaller diameter than the inner diameter of the outer cylinder for smooth vertical movement of the belt body, a lot of flow is generated during the vertical movement of the valve body.

이러한 밸브체의 유동은 공기배출홈의 크기를 정확하게 유지시킬 수 없고, 공기배출홈이 크게 형성된 부분으로 그린 타이어의 고무가 유입되어 밸브체의 상하동작을 마비시키어 결국 벤트장치가 기능을 하지 못하게 하는 문제점이 있는 것이다.The flow of the valve body cannot accurately maintain the size of the air discharge groove, and the rubber of the green tire flows into the portion where the air discharge groove is largely formed to paralyze the vertical movement of the valve body, thereby preventing the vent device from functioning. There is a problem.
