본 발명은 손잡이 있는 용기의 성형방법으로 먼저 용기주입구와 손잡이 부분을 성형한 뒤 용기 몸체를 성형하는 두단계로 이루어진 것이다.The present invention consists of a two-step forming method of the container with a handle first molding the container inlet and the handle portion and then forming the container body.

도 1은 본 발명의 손잡이 있는 용기의 사출성형방법에 따라 실시할 수 있는 장치의 실시예를 도시한 것으로서, 세 개의 작업면을 갖는 중앙의 회전대(10)와 각 작업면 중앙에 작업봉(12)이 설치되어 있다.Figure 1 shows an embodiment of the device that can be carried out according to the injection molding method of the handled container of the present invention, a rotary table 10 having three working surfaces and a working rod 12 in the center of each working surface ) Is installed.

상기 작업봉(12)은 용기 홀더의 기능과 공기가 불어넣어지는 관의 역할을 하는 것으로, 이 작업봉(12)의 내부에 공기 흡입관이 설치되어 있고 회전대(10)를 통해 공기를 불어 넣을 수 있으며 작업봉(12)의 선단 주위에 미세한 홀이 갖춰져 공기 흡입관을 통해 들어온 공기가 작업봉(12) 바깥으로 나갈 수 있게 되어 있다.The work rod 12 serves as a container holder and a function of the air blowing tube, the air suction pipe is installed inside the work rod 12 and can blow air through the swivel 10 In addition, a minute hole is provided around the tip of the working rod 12 to allow air that enters through the air suction pipe to go out of the working rod 12.

세 개의 작업면중 Ⅰ작업면은 본 발명의 제 1 성형단계, 즉 사출성형 또는 압출성형하는 작업면으로, 이 Ⅰ작업면에는 사출성형기 또는 압출성형기가 갖춰져 있으며, 전방으로 작업봉(12)에 끼워지고 후방으로 연화된 플라스틱이 주입될 수 있는 제 1 금형(14)이 갖춰져 있다. 이 제 1 금형(14)은 용기주입구와 손잡이 형태를 성형하고, 용기몸통이 될 부분은 성형되지 않은 프리폼 형태로 성형하게 된다.One of the three working surfaces is a working surface of the first molding step of the present invention, that is, injection molding or extrusion molding. The working surface is equipped with an injection molding machine or an extruder, and the working rod 12 is moved forwardly. It is equipped with a first mold 14 into which the inserted and softened back plastic can be injected. The first mold 14 is shaped into a container inlet and a handle, and the portion to be a container body is molded into an unformed preform.

Ⅱ작업면은 본 발명의 제 2 성형단계, 즉 블로우성형(blow molding)하는 작업면으로, 작업봉(12)을 통해 프리폼 부분에 공기를 불어넣어 용기 몸통 형태를 성형하는 과정을 수행하는 작업면이다.이 Ⅱ작업면에는 손잡이 아래부분의 용기몸통의 외곽 형태를 갖는 제 2 금형(16)이 갖춰져 있다. 이 제 2 금형(16)은 제 1 금형(14)을 손잡이 아래부분이 분리되게 하여 이를 분리시키고 용기 몸통 형태에 맞는 금형을 끼워 설치할 수 있게 된 것이 작업능률을 향상시키는 점에서 바람직하다.Ⅱworking surface is the second molding step of the present invention, that is, the blow molding (working surface), the working surface to perform the process of molding the shape of the container body by blowing air to the preform portion through the working rod 12 The second working surface is provided with a second mold 16 having an outer shape of the container body under the handle. The second mold 16 is preferable in that the first mold 14 can be separated from the lower part of the handle so as to be detached from the handle and fitted with a mold suitable for the shape of the container body, thereby improving work efficiency.

Ⅲ작업면은 성형단계를 거친 용기를 작업봉(12)에서 분리하는 작업면으로, 작업봉(12) 내측에 끼워 바깥방향으로 용기를 밀어낼 수 있게 된 밀판(18)이 갖춰져 있다.The third working surface is a working surface for separating the container that has undergone the molding step from the working rod 12, and is provided with a sealing plate 18 which is fitted inside the working rod 12 to push the container outward.

따라서 이 성형장치를 이용하면 연속작업이 가능하게 되는데, 이를 상세히 설명하면 다음과 같다.Therefore, the use of this molding apparatus enables a continuous operation, which will be described in detail as follows.

우선 Ⅰ작업면에 작업봉(12)에 맞춰 제 1 금형(14)을 설치하고 후방의 사출성형기 또는 압출성형기로부터 제 1 금형(14)내로 연화된 플라스틱을 주입하여 용기주입구와 손잡이 및 프리폼을 성형한다. 이후 사출성형기 또는 압출성형기와 제 1 금형(14)을 떼어내고 작업봉(12)에 성형된 반제품이 Ⅱ작업면으로 향하게 120°반시계방향으로 회전시킨다. 이어서 성형된 반제품이 손상되지 않게 조심하면서 제 2 금형(16)을 설치한다. 이때 제 2 금형(16)이 손잡이 아래부분만 교체할 수 있게 된 것이면 아래쪽의 금형만 교체하면 된다.First, the first mold 14 is installed in accordance with the working rod 12 on the working surface 12, and softened plastic is injected into the first mold 14 from the rear injection molding machine or the extruder, thereby forming the container inlet, the handle and the preform. do. Thereafter, the injection molding machine or the extruder and the first mold 14 are removed and the semi-finished product formed on the working rod 12 is rotated in a counterclockwise direction by 120 ° to face the II working surface. Subsequently, the second mold 16 is installed while being careful not to damage the molded semifinished product. At this time, if the second mold 16 can replace only the lower part of the handle, only the lower mold needs to be replaced.

작업봉(12)을 통해 공기를 불어넣어 반제품의 프리폼부분을 용기 몸통 형태로 성형한다. 프리폼내에 고른 압력이 가해질 수 있도록 작업봉(12)의 겉면에 팽창수단을 갖춰두면 공기가 직접 플라스틱에 닿지 않고 팽창수단을 부풀리면서 용기 몸통 형태로 성형할 수 있어 보다 바람직하다.Blowing air through the working rod 12 to form the preform portion of the semi-finished product in the form of a container body. If the expansion means is provided on the outer surface of the working rod 12 so that even pressure is applied in the preform, the air can be molded into a container body while inflating the expansion means without directly contacting the plastic.

이와 같이 용기 전체 형태가 성형되면 회전대(10)를 다시 반시계방향으로 120°회전시켜 Ⅲ작업면을 향하게 하고 밀판(18)을 작업봉(12) 내측에 끼워 바깥방향으로 이동시키면 용기가 작업봉(12) 바깥으로 밀려 떨어져 나가게 된다.When the entire shape of the container is formed in this way, the rotating table 10 is rotated 120 ° counterclockwise again to face the III work surface, and the plate 18 is inserted into the working rod 12 to move outward. (12) they are pushed out.

이 과정은 밀판(18)없이 손으로 잡아 빼낼 수도 있으나 자동생산에 적합한 방법으로는 상기 밀판(18)으로 밀어내게 하는 것이 바람직하다.This process may be pulled out by hand without the plate 18, but it is preferable to push it to the plate 18 as a method suitable for automatic production.

이와 같은 과정을 거쳐 손잡이 있는 용기를 연속적으로 제조할 수 있게 된다.Through this process it is possible to continuously manufacture a container with a handle.

상술한 바와 같은 본 발명의 손잡이 있는 용기의 성형방법은 2단계의 공정으로 작업을 수행하여 종래와 같이 손잡이를 별도로 성형하여 용기에 부착하는 공정을 생략할 수 있어, 제조비용을 절감할 수 있는 효과가 있다.The molding method of the container with a handle of the present invention as described above can perform the operation in a two-step process to omit the step of forming a handle separately and attaching to the container as in the prior art, thereby reducing the manufacturing cost There is.

또한 손잡이를 나사 등의 결합수단으로 결합하지 않으므로 인해 분리수거에 용이한 장점을 가질 수 있다.In addition, since the handle is not coupled with a coupling means such as a screw, it may have an advantage in easy removal.
