Description
본 고안은 성형공정에서 완성된 그린타이어를 모울드에 넣어 가류공정중 모울드의 표면에 의해 생성되는 식출고무를 제거하는 트리밍작업을 별도로 거치지 않고도 완제품타이어를 제조할 수 있도록 된 벤트리스 타이어 제조용 모울드에 관한 것이다.The present invention relates to a mold for manufacturing a tireless tire, which is capable of producing a finished tire without additional trimming to remove the extraction rubber produced by the surface of the mold during the vulcanization process. will be.
주지된 바와 같이 타이어제조시에는 성형이 완료된 그린타이어를 타이어모울드에 넣고 일정한 열과 압력증기를 가하여 타이어의 트레드를 형성시키는 가류공정을 거치게 되는 바, 이와 같이 가류공정시 상.하 모울드에 그린타이어를 넣어 완제품타이어를 생성할 때 종래에는 모울드제작시 이 모울드표면에 직접 공기구멍을 형성시킴에 따라, 완제품타이어 제조시 이 모울드의 공기구멍을 통해 식출고무가 연장된 형태로 생성되어 작업자가 별도의 트리밍작업(일명 사상작업이라고도 칭함)을 통해 일일이 타이어의 식출고무를 제거하는 후작업을 수행하게 되었다.As is well known, during the tire manufacturing process, the completed green tire is put in a tire mold and subjected to a vulcanization process in which a constant heat and pressure steam are applied to form a tread of the tire. When creating finished tires, air holes are formed directly on the surface of the mold when the mold is manufactured. Thus, when the finished tire is manufactured, the extraction rubber is extended through the air holes of the mold, so that the worker separately trims. Work (also known as finishing work) led to a post-work to remove the tire extraction rubber.
따라서 자연히 트리밍작업에 소요되는 인력과 이에 필요한 장비로 인해 각종 설비를 부가적으로 설치해야 했고, 제조단가를 낮추는 데에도 문제가 될 뿐 아니라 트리밍작업시 작업자의 부주의로 인해 타이어의 표면이 손상되어 완제품타이어의 질이 저하되고 불량률도 증가되게 되는 하나의 원인이 되었다.Therefore, it is necessary to install various equipment additionally due to the manpower required for trimming and necessary equipment, and it is not only a problem to lower the manufacturing cost, but also the surface of the tire is damaged due to the carelessness of the worker during trimming. It was one of the reasons that the quality of the tire was deteriorated and the failure rate was also increased.
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 모울드의 공기구멍구조를 개선하여 그린타이어 가류공정후 식출고무의 생성되는 것을 방지함으로써, 트리밍작업을 생략할 수 있으면서 완제품타이어의 외관미도 향상시키도록 된 벤트리스 타이어 제조용 모울드를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, and by improving the air hole structure of the mold to prevent the extraction of rubber after extraction of the green tire vulcanization process, trimming operation can be omitted, the appearance of the finished tire It is an object of the present invention to provide a mold for manufacturing a ventless tire, which is intended to enhance the beauty.

상기와 같은 목적을 달성하기 위한 본 고안은, 상.하부 모울드링의 트레드 형성부에 공기통로와 연통되는 삽입홈이 형성되고 이 삽입홈에 식입편이 강제끼움식으로 끼워지되, 이들 식입편과 삽입홈사이에 0.1 내지 0.2mm의 틈새가 형성되는 구도로 되어있다.The present invention for achieving the above object, the insertion groove is formed in communication with the air passage in the tread forming portion of the upper and lower mold ring and the insertion piece is inserted into the insertion groove by the force fitting method, these insertion pieces and the insertion It has a composition in which a gap of 0.1 to 0.2 mm is formed between the grooves.
이하, 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail based on the accompanying drawings.
제1도는 본 고안에 따른 모울드(1)의 부분단면도이고, 제2도는 제1도의Ⅰ - Ⅰ선 부분확대 분리 단면도이며, 제3도는 제2도의 부분확대 결합단면도이다. 도면에 도시된 바와 같이 본 고안은 상.하부 모울드(1)를 이루는 본체링(1a)안쪽면에 타이어의 트레드(2)를 형성시키게 되는 식입편(3)이 취부되되, 이 식입편(3)은 본체링(1a)의 안쪽면에 공기통로(4)와 연통되도록 형성된 삽입홈(5)에 강제끼워맞춤식으로 취부되도록 되어 있는 바, 이때 상기 본체링(1a)의 삽입홈(5)과 식입편(3)사이에는 0.1mm 내지 0.2mm정도의 틈새(6)가 형성되어 모울드(1)의 공기통로(4)와 연통되도록 되어 있다.1 is a partial cross-sectional view of the mold 1 according to the present invention, FIG. 2 is a partial enlarged cross-sectional view of the line I-I of FIG. 1, and FIG. 3 is a partially enlarged combined cross-sectional view of FIG. As shown in the drawings, the present invention is provided with an implantation piece (3) which forms the tread (2) of the tire on the inner surface of the main body ring (1a) forming the upper and lower mold (1), this implantation piece (3) ) Is forcibly fitted into the insertion groove 5 formed to communicate with the air passage 4 on the inner surface of the main body ring 1a, in which case the insertion groove 5 of the main body ring 1a and A gap 6 of about 0.1 mm to 0.2 mm is formed between the implant pieces 3 to communicate with the air passage 4 of the mold 1.
이와같이 본 고안에 따른 모울드(1)와 식입편은 제3도에 도시된 바와 같이 실제로 가공면들이 요철형상을 이루게 되기 때문에, 공기통로(4)와 연통되어 있는 삽입홈(5)에 식입편(3)이 억지끼움으로 맞추어 끼워질 때 이들의 취부면들 사이에 약 0.1mm내지 0.2mm정도의 틈새(6)가 형성됨에 따라, 화살표로 표시된 바와 같이 가류공정시 생성되는 압축공기 내지는 가스가 이들 틈새(6)사이를 거쳐 공기통로(4)로 빠져나가도록 되어 있다.As described above, the mold 1 and the implantation piece according to the present invention actually form the uneven surface as shown in FIG. 3, and thus the implantation piece is inserted into the insertion groove 5 in communication with the air passage 4. When 3) is fitted with interference fit, gaps 6 of about 0.1 mm to 0.2 mm are formed between these mounting surfaces, so that compressed air or gas generated during the vulcanization process as indicated by the arrows is It passes through the clearances 6 and exits to the air passage 4.
한편 고무는 재질특성상 틈새가 약 0.5mm이상이 되어야만 틈새를 통해 흘러나가 식출고무를 형성시킬 수 있게 되므로, 본 고안에 따른 모울드(1)는 가류공정시 발생되는 압축공기와 가스만 빠져나갈 수 있는 틈새(6)로 되어 있다.On the other hand, because the rubber material should be a gap of more than about 0.5mm due to the material properties to flow through the gap to form the extraction rubber, mold (1) according to the present invention can escape only the compressed air and gas generated during the vulcanization process It has a clearance 6.
그리고 여기서 상기 모울드(1)에 형성된 삽입홈(5)에 연통되는 공기통로(4)는, 강제압입으로 끼워 맞추어지는 식입편(3)의 일측 중앙부위에 위치되도록 하는것이 압축가스나 배기가스를 배출하는데 효과적이다.In this case, the air passage 4 communicating with the insertion groove 5 formed in the mold 1 is located at the central portion of one side of the insertion piece 3 to be fitted by forced pressurization. It is effective to discharge.
상기와 같이 본 고안에 따른 모울드, 공기통로를 통해 그린타이어의 가류공정시 발생되는 압축공기와 가스만이 빠져나가게 되고 식출고무의 유출은 차단됨으로서, 모울드에서 타이어를 추출한 다음 이후 공정인 트리밍작업을 생략할 수 있을 뿐만 아니라 완제품 타이어의 외관이 불량해지는 것을 최소화시키는 효과가 있다.As described above, only the compressed air and gas generated during the vulcanization process of the green tire through the mold and the air passage of the present invention are discharged and the outflow of the extraction rubber is blocked, thereby extracting the tire from the mold and then trimming the process. Not only can be omitted, there is an effect of minimizing the appearance of the finished tire is bad.
