1 : 틀체 12, 12' : 축1: frame 12, 12 ': axis

본 고안은 합성수지 원료를 투입한 금형을 원주방향으로 회전시키면서 일정 온도의 열을 가하여 용융된 원료가 금형의 내벽에 균일하게 확산 성형되도록 하는 대형 합성수지 용기의 성형장치에 관한 것으로, 특히 상기한 금형을 좌우로 시이소오 장동시키도록 구성한 것이다.The present invention relates to a molding apparatus of a large synthetic resin container in which the molten raw material is uniformly diffused and molded on the inner wall of the mold by rotating a mold in which the synthetic resin raw material is injected in the circumferential direction, and in particular, the molding of the mold. It is configured to be Shio-Seo Chang.

종래, 합성수지 용기를 성형함에 있어서는 일반적으로 사출성형, 가압성형, 회전성형 등의 방식이 있는바, 본고안은 상기한 방식중, 회전성형방식에 의하여 대형 합성수지용기를 성형함에 있어서 금형을 회전과 동시에 이를 좌우로 시이소오 작동시켜서 용융수지가 금형내에 균일하게 확산성형 되도록 하는 장치로서 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.Conventionally, in molding a synthetic resin container, there are generally methods such as injection molding, press molding, and rotation molding. In this method, the mold is rotated at the same time in forming a large synthetic resin container by a rotation molding method. It is a device for allowing the molten resin to be uniformly diffused in the mold by operating the iso-so on the left and right as described in detail by the accompanying drawings as follows.

4각형이 틀체(1) 위의 양편에 2쌍의 축받이(2), (2'), (3), (3')를 마련하여 이들 사이에 바퀴(5), (5'), (6), (6')를 착설한 회전축(4), (4')을 축설하고 별도로 중간부가 분리되도록 만든 성형 금형(7), (7')의 각 외측부에는 다수의 지지구(8), (8')로 지지시킨 지지륜(10), (10')을 상기한 바퀴(5), (5'), (6), (6')위에 재치하여 회전되게 하고 상기한 틀체(1)에는 복수의 가스 버어너(11)를 설치하여 그 버어너(11)로 상기한 성형금형(7), (7')을 가열하도록 구성하며, 상기한 틀체(1)의 앞·뒷편의 중앙부에는 축(12), (12')을 축설하여 이를 도시하지 않은 동력원에 의하여 주기적으로 좌우회동시키는데 따라 상기한 틀체(1)가 시이소오 작동되도록 구성한 것이다.A quadrilateral is provided with two pairs of bearings (2), (2 '), (3) and (3') on both sides of the frame (1), with wheels (5), (5 ') and (6) between them. ), A plurality of supports 8, and () are formed on each outer side of the molding dies 7 and 7 ', which are formed by laying the rotary shafts 4 and 4' on which the 6 and 6 'are mounted, and separately separating the intermediate part. 8 ') supporting wheels 10, 10' are mounted on the wheels 5, 5 ', 6, and 6' and rotated. A plurality of gas burners 11 are provided so as to heat the above-mentioned molding dies 7 and 7 'with the burners 11, and the shafts are provided at the centers of the front and rear sides of the frame 1 above. (12) and (12 ') are constructed so that the above-mentioned frame 1 is operated by seesaw by periodically rotating left and right by a power source (not shown).

도면중 미설명 부호9, 9'는 걸림턱이고, 13은 결착구, 14는 성형된 합성수지 용기이다.In the drawings, reference numerals 9 and 9 'are locking jaws, 13 are fasteners, and 14 are molded synthetic resin containers.

이와 같이 구성된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

성형 금형(7), (7')내에 합성수지 원료를 적당량 투입하여 결착구(13)에 의하여 서로 결합시킨 다음 양편의 지지륜(10), (10')을 제1도 및 제2도와 같이 각기 회전바퀴(5), (5'), (6), (6')위에 재치하고 통상의 동력기계 장치에 의하여 회전축(4), (4')을 동일방향으로 일정 속도로 회전시키고 동시에 성형금형을 재치한 전체의 4각 틀체(1)는 도시하지 않은 동력장치에 의하여 주기적으로 축(12), (12')을 좌·우로 회동시켜서 제3도의 (a), (b)와 같이 (R)각 만큼 좌우교대로 기울어지면서 시이소오 작동되게 하고 아울러서 틀체(1)에 설치된 가스버어너(11)에 의하여는 일정 온도의 고열이 성형 금형(7), (7')의 외면을 가열하게 하므로 투입된 합성수지 원료가 녹이면서 금형내에 고르게 확산되는 것이다.A suitable amount of synthetic resin material is introduced into the molding dies 7 and 7 'and combined with each other by the binding holes 13, and then the supporting wheels 10 and 10' of both sides are respectively as shown in Figs. It is placed on the rotary wheels (5), (5 '), (6) and (6') and rotates the rotating shafts (4) and (4 ') at a constant speed in the same direction by a conventional power machinery, and at the same time The entire quadrangular frame 1 on which the gears are mounted is periodically rotated between the shafts 12 and 12 'by the power unit (not shown) to the left and right, as shown in (a) and (b) of FIG. Since it is inclined alternately by each side and is operated, the gas burner 11 installed on the frame 1 heats the outer surfaces of the molding dies 7 and 7 'with a high temperature. The injected synthetic resin raw material melts and is evenly spread in the mold.

일정 시간이 경과된 후에 가열을 중지하고 성형 금형(7), (7')의 전후 좌우의 작동을 계속시키면서 금형상에서 냉각수를 살포하여 이를 냉각시키고 완전히 식은 후에는 작동을 멈추고 제4도의 (b)와 같이 결착구(13)를 풀고 금형을 양편으로 분리시키면 성형된 합성수지 용기(14)를 얻게되는 것이다.After a certain time has elapsed, the heating is stopped and the cooling dies are sprayed on the mold while cooling the molds 7 and 7 'and the operation is continued. Loosening the binder 13 and separating the mold into both sides as shown to obtain a molded synthetic resin container (14).

이와 같이 본 고안은 합성수지 원료를 투입한 성형 금형을 일정하게 원주방향으로 회전시키는 동시에 이를 좌우로 시이소오 작동시키면서 버어너로 가열하는데 따라 용융수지가 금형 내벽에 균일하게 확산되게 하므로 두께가 일정한 대형의 합성수지 용기를 능률적으로 얻을 수 있는 효과가 있는 것이다.As such, the present invention rotates the molding die into which the synthetic resin raw material is injected in the circumferential direction and heats the burner with the burner while operating it from side to side, while allowing molten resin to be uniformly spread on the inner wall of the mold. It is effective to obtain a plastic container efficiently.
