Description

냉장고 도어의 포켓지지부 제조방법Manufacturing method of pocket support of refrigerator door

본 발명은 냉장고 도어의 포켓지지부 제조방법에 관한 것으로, 보다 상세하게는 블로우 몰딩(blow moulding) 기법에 의해 제조되는 냉장고 도어의 포켓가이더를 그 바닥면에서 지지하는 포켓지지부의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a pocket support of a refrigerator door, and more particularly, to a method of manufacturing a pocket support for supporting a pocket guider of a refrigerator door manufactured by a blow molding technique on its bottom surface.

일반적으로 냉장고의 도어는 그 외테두리에 밀폐용 가스켓을 부착하여 냉장고의 냉동실 또는 냉장실의 고내 냉기가 외부로 누설되지 않도록 하여 폐쇄하여 주는 부품이며, 또한 그 내측에 여유 공간을 적절하게 분할하여 도어포켓부를 형성하고 각 포켓에 각종 수납물을 저장할 수 있도록 함으로서 냉장고의 저장용적을 최대로 활용할 수 있도록 하고 있다.In general, the door of the refrigerator is a part that attaches a gasket for sealing to the outer edge of the refrigerator to close the refrigerator's freezer compartment or the cold inside of the refrigerator compartment so that it does not leak to the outside. By forming a part and storing various things in each pocket, it is possible to make maximum use of the storage capacity of the refrigerator.

예컨데, 이러한 도어포켓의 상측에는 계란과 같은 알(卵)류를 보관하도록 하고, 그 하측에는 용액을 수용하는 병용기 등을 보관할 수 있도록 병포켓이 마련되어 있다.For example, a bottle pocket is provided on the upper side of the door pocket to store eggs such as eggs, and a lower side of the door pocket to store a bottle containing a solution.

이와 같은 포켓들이 마련된 냉장고 도어는 도시된 도 1 과 같이, 각 포켓가이더(10)들이 장착되는 부위에 상기 냉장고 도어(20)의 내부 공간을 적절하게 분할하여 상기 각 포켓가이더(10)들을 지지할 수 있는 장치로서 비드(bead)(30)가 형성된다.As shown in FIG. 1, the refrigerator door provided with such pockets may support the respective pocket guiders 10 by appropriately dividing the internal space of the refrigerator door 20 at the portion where the pocket guiders 10 are mounted. A bead 30 is formed as a viable device.

따라서, 별도로 제작된 포켓가이더(10)가 상기 비드(30)에 안착되면서 도어(20)의 양측단 내면에 고정되어 냉장고의 도어포켓을 이루게 된다.Accordingly, the separately manufactured pocket guider 10 is fixed to the inner surface of both ends of the door 20 while seated on the bead 30 to form a door pocket of the refrigerator.

그리하여, 이들 공간에 캔, 음료수병 등을 수납하거나 혹은 용액을 수용하고 있는 용기, 이를테면 참기름병, 식용류병 혹은 치이즈 등과 같이 다양한 수납물품을 저장하여 보관하고 있다.Thus, cans, beverage bottles and the like are stored in these spaces, or containers containing a solution, such as sesame oil bottles, edible bottles or cheeses, are stored and stored.

그런데, 냉장고 도어가 몰드물로 일반적인 사출성형방법에 의하여 제조될 때에는 별 문제가 없는 데 비하여, 최근에 냉장고의 제조비용을 절감하기 위하여 대두되고 시행되고 있는 블로우 몰딩(blow moulding) 방법에 의해 냉장고 도어를 일체로 성형하여 제조함으로 인하여 냉장고의 포켓가이더를 그 바닥면에서 지지하는 비드의 제작이 상당히 어렵다는 문제가 도출되었다.By the way, when the refrigerator door is manufactured by a general injection molding method with a mold, there is no problem, whereas the refrigerator door is blown by a blow molding method, which has recently emerged and implemented to reduce the manufacturing cost of the refrigerator. Since the molding is integrally manufactured, it has been found that the production of beads supporting the pocket guider of the refrigerator at the bottom thereof is quite difficult.

즉, 이러한 블로우 몰딩기법은 성형틀에 몰딩컴파운드를 주입하면서 강한 에어(air)를 블로잉(blowing)시켜 상기 몰딩컴파운드가 성형틀의 외벽쪽으로 공기압에 의하여 부풀려 밀려들면서 소정형상을 이룰때에 냉각시켜 그 형상을 그대로 유지토록 하는 기법이기 때문에 냉장고 도어의 통체를 형성하기에는 적합하나 그 내측에 형성되는 비드형상을 제조하기는 난해하며, 아울러 상기 비드형상이 제조된다하더라도 이 비드의 형상이 좁고 돌출길이가 짧아 비드, 즉 포켓지지부로서의 기능이 저하되는 문제가 있었다.That is, the blow molding technique blows strong air while injecting a molding compound into a mold, thereby cooling the mold when the molding compound is inflated by pneumatic pressure toward the outer wall of the mold to achieve a predetermined shape. Although it is suitable to form the cylinder body of the refrigerator door, it is difficult to manufacture the bead shape formed therein, and even if the bead shape is manufactured, the shape of the bead is narrow and the protruding length is short. That is, there existed a problem that the function as a pocket support part falls.

본 발명은 상기한 종래기술의 제반 문제점을 해결하기 위하여 안출된 것으로서, 블로우 몰딩 기법에 의하여 일체로 제조되는 냉장고의 도어에서 이 도어 내측을 소정공간씩 구획하여 도어포켓부를 형성할 때에 포켓가이더를 지지하는 포켓지지부를 별도로 제작하여 블로우 몰딩으로 제조되는 냉장고 도어의 금형에 인서트(insert)하여 사출 성형시 포켓지지부가 냉장고 도어와 일체 성형될 수 있도록 한 제조방법을 제공하기 위한 것이다.The present invention has been made to solve the above-mentioned problems of the prior art, and the pocket guider is formed when the door pocket part is formed by partitioning the inside of the door by a predetermined space in the door of the refrigerator manufactured integrally by a blow molding technique. It is to provide a manufacturing method so that the pocket support to be separately manufactured by inserting into the mold of the refrigerator door manufactured by blow molding to allow the pocket support to be integrally molded with the refrigerator door during injection molding.

본 발명에 따른 냉장고 도어의 포켓지지부 제조방법의 특징은, 도어포켓의 포켓지지부를 갖는 냉장고 도어를 블로우 몰딩 기법으로 제조하는 방법에 있어서, 결합단부를 갖는 상기 포켓지지부를 사출하여 성형한 후에 상기 포켓지지부의 결합단부와 대응되는 형상으로 상기 냉장고 도어의 금형을 개조하여 상기 포켓지지부의 결합단부가 상기 냉장고 도어의 금형에 인서트(insert)되어 상호 일체로 블로우 몰딩 제조되도록 한 냉장고 도어의 포켓지지부 제조방법을 제공하게 된다.A feature of the method for manufacturing a pocket support part of a refrigerator door according to the present invention is a method of manufacturing a refrigerator door having a pocket support part of a door pocket by a blow molding technique, wherein the pocket support part having a coupling end is molded by injection molding the pocket support part. Method of manufacturing the pocket support of the refrigerator door to modify the mold of the refrigerator door to a shape corresponding to the coupling end of the support so that the coupling end of the pocket support is inserted into the mold of the refrigerator door to be blow molded integrally with each other. Will be provided.

이하에서는, 본 발명 냉장고 도어의 포켓지지부 제조방법에 대한 선호된 일 실시예를 첨부한 도면을 참조하여 보다 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of a method for manufacturing a pocket support of the refrigerator door of the present invention will be described in more detail.

도 2는 본 발명에 따른 냉장고의 도어포켓부를 도시한 냉장고 도어의 성형방법을 도시한 사시도로서, 먼저 냉장고의 도어포켓부에 설치되는 포켓가이더를 그 바닥면에서 지지하여 수납물이 저장될 수 있도록 하여 주는 포켓지지부(50)를 별도로 사출 성형하여 냉장고 도어의 금형에 인서트(insert)되는 과정을 도시한 것이다.Figure 2 is a perspective view showing a method of forming a refrigerator door showing a door pocket portion of the refrigerator according to the present invention, first to support the pocket guider installed in the door pocket portion of the refrigerator from the bottom surface so that the things can be stored It shows the process of inserting into the mold of the refrigerator door by separately injection molding the pocket support (50).

여기에서, 도면에 도시한 바는, 금형자체를 도시하지 않고 가상선에 의해 냉장고 도어 형상을 갖는 다이(die)에 성형품인 포켓지지부(50)가 인서트되고 있는 상태를 나타낸 것이다.Here, the figure shows the state in which the pocket support part 50 which is a molded article is inserted in the die which has a refrigerator door shape by an imaginary line, without showing the metal mold itself.

바꾸어 말하면, 상기 포켓지지부(50)는 상기 금형에 인서트되면서 그 결합단부가 금형에 의해 형성된 캐비티(cavity)와 연통되도록 하여 유입되는 몰딩 컴파운드(moulding compound)와 접촉되고 냉각되면서 동시에 고형화되어 일체로 성형되도록 한 것이다.In other words, the pocket support 50 is inserted into the mold and its coupling end is brought into communication with the cavity formed by the mold, thereby contacting and cooling the molding compound that is introduced, and simultaneously solidified and integrally molded. It was made possible.

상기 포켓지지부(50)는 냉장고의 도어포켓부 저면을 형성하여 상기 도어포켓부에 수납되는 수납물품을 저장하여 주는 곳으로서, 사용자의 미감을 자극할 수 있도록 다양한 색상을 갖도록 성형한 후에 냉장고 도어의 금형에 인서트되게 할 수도 있을 것이다.The pocket supporting part 50 forms a bottom surface of the door pocket part of the refrigerator to store the stored items stored in the door pocket part, and is molded to have various colors to stimulate the user's aesthetics. It may be inserted into a mold.

예컨데, 상기 도어포켓부와 동일재질과 동일색상으로 먼저 포켓지지부(50)를 성형한 후에 이 포켓지지부(50)를 냉장고 도어의 금형에 인서트한 후, 블로우 몰딩시켜 상기 포켓지지부(50)와 냉장고 도어가 일체로 성형되게 할 수도 있을 것이며, 상기 도어포켓부와 서로 다른 재질과 서로 다른 색상으로 먼제 포켓지지부(50)를 성형한 후에 이 포켓지지부(50)를 냉장고 도어의 금형에 인서트한 후, 블로우 몰딩시켜 상기 포켓지지부(50)와 냉장고 도어가 일체로 성형되게 할 수도 있을 것이다.For example, after forming the pocket support 50 with the same material and the same color as the door pocket, the pocket support 50 is inserted into a mold of the refrigerator door, and then blow molded to support the pocket support 50 and the refrigerator. The door may be molded integrally, and after the pocket support 50 is formed in a different material and a different color, the pocket support 50 is inserted into a mold of the refrigerator door. Blow molding may be such that the pocket support 50 and the refrigerator door are integrally molded.

한편, 상기 포켓지지부(50)의 결합단부는 그 조립을 용이하게 하면서 쉽게 이탈되지 않도록 하기 위하여, 볼 조인트(ball joint)의 자웅(雌雄) 형상으로 형성한다.On the other hand, the coupling end of the pocket support 50 is formed in a male shape of a ball joint in order to facilitate its assembly and not to be easily separated.

예컨데, 볼 조인트의 자형을 냉장고 도어의 포켓지지부(50)의 결합단부에 형상하면, 이 포켓지지부(50)가 삽입고정되는 냉장고 도어 형상의 금형에는 캐비티와 연통되도록 볼 조인트의 웅형을 형성하며, 그 반대로 포켓지지부(50)에 볼 조인트의 웅형을 형성하면 금형에는 볼 조인트의 자형을 형성하도록 하는 바, 이는 상호간에 조립과 형성이 수월한 방향으로 형성함이 바람직하다.For example, when the shape of the ball joint is formed at the coupling end of the pocket support 50 of the refrigerator door, a male of the ball joint is formed in the refrigerator door-shaped mold into which the pocket support 50 is inserted and fixed so as to communicate with the cavity. On the contrary, when the male of the ball joint is formed in the pocket support 50, the male of the ball joint is formed in the mold, which is preferably formed in an easily assembled and formed direction.

이러한 형상과 구조로 사출 성형된 포켓지지부(50)를 냉장고 도어 형상의 금형에 인서트하여 고정한다.The pocket support 50 injection-molded in this shape and structure is inserted into and fixed to a mold having a refrigerator door shape.

그런 후에, 몰딩컴파운드를 금형의 스프루(sprue)에 주입하여 냉장고의 도어와 상기 포켓지지부(50)가 일체로 성형되도록 함으로서 종래 블로우 몰딩 기법으로 제조되는 냉장고 도어의 포켓지지부 성형의 단점을 보완할 수 있게 된다.Thereafter, the molding compound is injected into the sprue of the mold so that the door of the refrigerator and the pocket support 50 are integrally formed so as to compensate for the disadvantage of molding the pocket support of the refrigerator door manufactured by the conventional blow molding technique. It becomes possible.

이상에서 설명한 바와 같이 본 발명에 따른 냉장고 도어의 포켓지지부 제조방법을 제공함으로써, 블로우 몰딩되어 제조되는 냉장고 도어의 포켓부를 기존과 동일하게 냉장고 도어에 포켓지지부가 일체로 성형되기 때문에 포켓가이더의 지지력이 우수하고 별도의 포켓지지부 보강을 필요로 하지 않기 때문에 제조단가를 절감시키는 효과를 제공하는 것이다.As described above, by providing a method of manufacturing a pocket support part of a refrigerator door according to the present invention, since the pocket support part of the refrigerator door manufactured by blow molding is molded in the same way as the conventional one, the support force of the pocket guider is increased. Excellent and does not require a separate pocket support reinforcement is to provide an effect of reducing the manufacturing cost.
