본 고안은 용해된 합성수지를 형속에 주입한후 내부에 공기를 불어넣어서 병과같이 중공품(中空品)을 성형하는 취입성형기(BLOW MOLDING)에 있어서, 성형붕을 중공품의 두께와 형상의 일정하게 성형되도록 하는 취입성형기의 성형봉 구동장치에 관한 것이다.The present invention is a blow molding machine in which a molten synthetic resin is injected into a mold and then blows air into the hollow mold to form a hollow product, such as a bottle. The present invention relates to a forming rod driving device of a blow molding machine.

일반적으로 알려진 취입성형기는 형속에 취입공이 천공된 성형봉을 넣은 상태에서 합성수지용액을 상기 성형봉의 외주면에 위포된 상태로 주입시킨후 성형봉을 통하여 공기를 불어넣어 중공품을 성형하도록 되어 있다.In general, the blow molding machine is to inject a synthetic resin solution in a state in which the injection hole is punched into the mold in a state that is in a state of being superimposed on the outer peripheral surface of the molding rod, and then blows air through the molding rod to form a hollow product.

그러나, 상술한 종래 취입성형기는 성형봉이 고정상태에서 불어 넣어지는 공기의 압력에만 의존하여 수지가 부풀거나 늘어나면서 중공물품이 성형되는 것이어서 부분적으로 두께가 일정하지 않거나 또는 예를들어 병목과 병체와의 중심이 어긋나게 형성되는 결점이 있는 것이다.However, the above-mentioned conventional blow molding machine is a hollow article that is formed as the resin swells or expands depending on only the pressure of the air that is blown in the fixed state of the forming rod, so that the thickness thereof is not constant in part, There is a defect that the center is shifted.

따라서 본 고안에서는 상기한 성형봉을 중공물품이 성형되는 길이방향으로 이동시켜 성형봉 외주에 위포된 수지가 횡면과 종면이 동시에 알맞게 늘어나면서 부풀려 성형되도록 하므로서 물품의 두께가 일정하고 중심이 똑바르게 성형되도록 함을 목적으로 하는 것이다.Therefore, in the present invention, by moving the forming rod in the longitudinal direction in which the hollow article is molded, the resin placed on the outer periphery of the forming rod is swelled in a manner that the cross section and the longitudinal side thereof are appropriately stretched at the same time, so that the thickness of the article is uniform and the center is molded straight. The purpose is to make it possible.

상기한 본고안의 목적을 달상하기 의한 성형봉 이동수단으로는 성형봉을 이동시키는 실린더와 이 실린더내에서 공압 또는 유압으로 작동되는 피스톤과 상기 성형봉과 피스톤을 연결하는 연결봉을 파함한다.The molding rod moving means for achieving the object of the present invention includes a cylinder for moving the molding rod, a piston operated by pneumatic or hydraulic pressure, and a connecting rod connecting the molding rod and the piston.

Referring to FIG. 1, the forming rod 1 has a connecting rod having a smaller diameter. (2) integrally formed or separately formed and connected to connect the piston (3) to the end of the connecting rod (2), the connecting rod (2) between the bottleneck forming portion (3) before connecting the piston (3) 4) is inserted into the inner diameter (6) of the air cylinder (5) is formed, the size of the inner diameter (6) is larger than the outer diameter of the connecting rod (2), smaller than the outer diameter of the forming rod (1) inner end of the forming rod (1) When the inner diameter 6 is closed when it is in close contact with the outer end shaft of the inner diameter 6 of the jaw 1 ', the cylinder 5 is a soft rod of the above-mentioned forming rod 1 using the mounting bracket 7. (2) and mounting plate (8) for driving the piston (3), the mounting bracket (7) The molding air blown into the blowing hole 7 'is blown into the blowing hole 7' with the air cylinder 5 and is mounted on the rotary plate 8 together with the air cylinder 5 to blow the blowing air into the air cylinder 5 The exhaust plate 8 is exhausted to the forming rod 1 side through the inner diameter 6 of the c). The rotation plate 8 extends several holes 9 in the horizontal direction to open the piston holders 10 and 10 '. The cylinders 11 connected to both ends are inserted into the holes 9, and the bottom of the rotation plate 8 is positioned at both ends of the holes 9 at the input holes 12 and 12 '. When the hydraulic pressure or pneumatic pressure is supplied to the input hole (12) (12 ') to apply a driving pressure to the piston (3) through the inner space of the piston support (10) (10'), the cylinder ( The procedure for inserting 11 into each hole 9 is to insert the cylinder 11 into the connecting rod 2 so that the piston 3 is positioned between the piston supports 10 and 10 '. After that, the cylinder 11 is pushed into the hole 9 and the mounting bracket 7 is fastened to the outer surface of the hole 9 by bolts.

도면중 부호 13은 금형을 나타낸 것으로서 이 금형(13)은 상형판(14)과 하형판(14')으로 분할되어 상하로 형개되는 것이다.In the figure, reference numeral 13 denotes a mold, and the mold 13 is divided into an upper mold plate 14 and a lower mold plate 14 'to be opened up and down.

이상과 같이 된 본 고안은 제2도에 표현된 바와같이 에어실린더(5)의 경목성형부(4)와 성형봉(1)표면에 용해수지를 위포시킨 다음 금형(13)내에 넣고, 이후 취입공(7')에는 성형공기를 불어넣고 입력공(12)에는 유압 또는 공압을 공급시키면 피스톤받이(10)의 내공간을 통하여 피스톤(3)에 압력이 가하여져 피스톤(3)이 피스톤받이(10')내측으로 이동되고 이에따라 성형봉(1)이 에어실린더(5)의 내경(6)첨단으로 부터 이탈되어 성형품의 길이방향으로 이동되는데 성형공기는 성형봉(1)의 내단턱(1′)이 내경(6)으로부터 이탈되는 순간부터 내경을 통하여 성형봉(1)의 표면과 용해수지 사이로 불어넣어져 중공물품을 성형하게 되는 것이고, 성형된 중공물품을 이젝트시킨 다음 입력공(12')측으로 압력을 공급하여 피스톤(3)을 피스톤받이(10)측으로 이동시켜 성형봉(1)을 원위치로 환원하게 되는것이다.The present invention as described above, as shown in FIG. 2, dissolve the resin on the surface of the hard wood forming portion 4 and the forming rod (1) of the air cylinder (5) and then put in the mold (13), and then blown Blowing the forming air into the ball (7 ') and supplying hydraulic or pneumatic to the input hole 12, the pressure is applied to the piston (3) through the inner space of the piston support (10), the piston (3) the piston support ( 10 ') and the molding rod 1 is moved away from the inner diameter 6 edge of the air cylinder 5 and moved in the longitudinal direction of the molded article. ) Is blown between the surface of the forming rod (1) and the dissolving resin through the inner diameter from the moment it is separated from the inner diameter (6) to form a hollow article, and ejected the molded hollow article and then the input hole (12 ') Pressure to the side to move the piston (3) to the piston receiving (10) side to form the forming rod (1) Will be returned to its original position.

이상과 같이 본 고안은 성형봉(1)을 중공물품의 성형방향으로 이동시키면서 중공물품을 성형하게 된것이어서 병목성형부(4)와 성형봉(1)외주면에 위포된 용해수지가 일정한 속도로 길게 늘어나면서 부풀어져 성형하게되어 증래 고정성형봉을 이용한 것보다는 성형물품의 병목으로 부터 이어지는 병전체의 두께가 일정하게 성형되고, 병목과 병체가 중심이 곧은 형태로 성형되어 양질의 수지병을 제조하게되는 작용효과를 나타내는 것이다.As described above, the present invention is to mold the hollow article while moving the forming rod 1 in the molding direction of the hollow article, so that the melted resin placed on the bottleneck forming portion 4 and the outer circumferential surface of the forming rod 1 is kept at a constant speed. As the swelling and swelling is formed, the thickness of the whole bottle from the bottleneck of the molded article is uniformly molded, and the bottleneck and the bottle are molded in a straight shape rather than using a fixed rod. It is to show the effect.
