Description

냉장고의 일체형 도어선반의 제조방법Manufacturing method of integrated door shelf of refrigerator

본 발명은 냉장고의 일체형 도어선반의 제조방법에 관한 것으로, 특히 도어선반을 기존의 도어 라이너와 일체로 성형함에 있어서, 로테이션 몰딩방법을 사용하므로, 작업공수가 줄어들고, 도어선반의 탈거 또는 깨짐등의 불량용인을 제거하여 비용을 절감시킨 냉장고의 일체형 도어선반의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing an integrated door shelf of a refrigerator, and in particular, in forming the door shelf integrally with an existing door liner, since the rotation molding method is used, the labor time is reduced, and the door shelf is removed or broken. The present invention relates to a method for manufacturing an integrated door shelf of a refrigerator in which cost reduction is eliminated.

종래의 기술에 의한 냉장고의 도어선반은 도 1 및 도 2에 도시한 바와 같이, 도어 라이너(1)에 안내돌기(2)를 형성하고, 상기 안내돌기(2)에 도어선반(3)의 삽입홈(4)이 삽입되어 도어선반(3)이 고정되며, 도어라이너(1)는 도어(5)에 나사(6)를 이용하여 체결고정된다.As shown in FIGS. 1 and 2, the door shelf of the refrigerator according to the related art forms a guide protrusion 2 on the door liner 1, and inserts the door shelf 3 into the guide protrusion 2. The groove 4 is inserted to fix the door shelf 3, and the door liner 1 is fastened and fastened to the door 5 by using a screw 6.

상기와 같은 구성에 의해 결합되어 도어선반(3)과 도어라이너(1) 사이에 병(7)등과 같은 수납물을 저장한다.Combined by the configuration as described above to store an object such as a bottle (7) between the door shelf 3 and the door liner (1).

그러나, 이러한 종래의 기술에서는 도어라이너(1)와 도어선반(3)이 분리되어 있어 도어선반(3)을 도어라이너(1)에 삽입해야 제기능을 발휘하며, 도어선반(3)의 탈거 깨짐등의 문제가 발생하고, 삽입 고정하는 공수가 많아지는 문제점이 있다.However, in such a conventional technology, the door liner 1 and the door shelf 3 are separated, so that the door shelf 3 must be inserted into the door liner 1 to perform proper function, and the removal of the door shelf 3 is broken. There arises a problem such that the number of times to insert and fix the problem occurs.

따라서, 본 발명의 목적은 상기와 같은 문제점을 해결하기 위해 안출한 것으로, 도어선반을 기존의 도어 라이너에 삽입시킬 필요없이 도어라이너와 일체로 형성함으로써, 작업공수가 줄어들고, 도어선반의 탈거 깨짐등의 불량요인을 제거하여 비용을 절감시킨 냉장고의 일체형 도어선반의 제조방법을 제공함에 있다.Accordingly, an object of the present invention is to devise to solve the above problems, by forming the door shelf integrally with the door liner without having to insert the existing door liner, reducing the number of work, breakage of the door shelf, etc. The present invention provides a method for manufacturing an integrated door shelf of a refrigerator that reduces costs by eliminating defective factors.

이러한 본 발명의 목적은, 냉장고의 도어 뒷면에 설치되는 도어라이너와, 그 도어라이너와 결합되는 도어선반을 일체로 제조함에 있어서, 상기 도어라이너의 형상이 성형된 금형내에 분말수지를 넣어 상,하,좌,우로 회전시켜 좌우대칭인 일체형 선반을 형성하고, 상기 일체형 선반의 중심을 절단하여 제조함으로써 달성된다.The object of the present invention, in the manufacture of the door liner installed on the back of the door of the refrigerator and the door shelf coupled to the door liner integrally, put the powder resin in the mold of the shape of the door liner up, down It is achieved by forming left and right symmetrically integrated shelves by cutting left and right, and cutting the center of the integrated shelves to produce them.

이하, 본 발명에 의한 냉장고의 일체형 도어선반의 제조방법을 첨부도면에 도시한 실시예에 따라서 설명한다.Hereinafter, the manufacturing method of the integrated door shelf of the refrigerator by this invention is demonstrated according to the Example shown in an accompanying drawing.

도 3 및 도 4는 본 발명에 의해 제조된 냉장고의 일체형 도어선반을 나타내는 것으로써, 도 3은 사시도이고, 도 4는 단면도이며, 도 5a 내지 도 5c는 본 발명에 의한 냉장고의 일체형 도어선반을 성형하는 방법을 나타낸 설명도를 각각 보인 것이다.3 and 4 show an integrated door shelf of the refrigerator manufactured according to the present invention, FIG. 3 is a perspective view, FIG. 4 is a cross-sectional view, and FIGS. 5A to 5C show an integrated door shelf of the refrigerator according to the present invention. Explanatory drawing which showed the method of shaping | molding is shown, respectively.

이에 도시한 바와 같이, 본 발명에 의한 냉장고의 일체형 도어선반은 냉장고의 도어(5) 뒷면에 배치되는 도어라이너(11a)와, 그 도어라이너와 연결되는 도어선반(11b)을 일체로 한 일체형 도어선반(11)으로 형성된다.As shown in the drawing, the integrated door shelf of the refrigerator according to the present invention is an integrated door in which the door liner 11a disposed on the back of the door 5 of the refrigerator and the door shelf 11b connected to the door liner are integrated. It is formed as a shelf (11).

상기 일체형 도어선반(11)의 하면에 냉기가 유동될 수 있도록 냉기흐름공(12)이 형성된다.Cold air flow holes 12 are formed on the lower surface of the integrated door shelf 11 to allow cold air to flow.

종래 구성과 동일 부분에 대하여는 동일부호를 부여 하였다.The same reference numerals are given to the same parts as in the conventional configuration.

이하, 본 발명에 의한 냉장고의 일체형 도어선반의 제조방법 및 작용효과를 설명한다.Hereinafter, the manufacturing method and the effect of the integrated door shelf of the refrigerator according to the present invention will be described.

도 5a 내지 도 5c를 참조로 설명하면 도 5a와 같이 여러단으로 형성된(13)을 도어 라이너 및 선반의 형상으로 제작하고, 상기 금형(13)안에 원재료 분말수지(14)를 넣고 X축과 Y축을 중심으로 상하좌우로 돌린다. 이렇게 금형을 상하좌우로 돌리면서 주위에 열을 가하면 원재료 분말수지(14)가 녹으면서 일체형 도어선반의 금형(13)공간으로 흘러들어가게 된다.Referring to Figures 5a to 5c as shown in Figure 5a to form a plurality of stages 13 formed in the shape of the door liner and shelf, and put the raw material powder resin 14 in the mold 13 and the X-axis and Y Rotate up, down, left and right around the axis. When the mold is heated up, down, left, and right as described above, the raw material powder resin 14 melts and flows into the mold 13 space of the integrated door shelf.

일체형 도어 선반의 금형공간은 도어라이너와 선반부위로 제작되어 있으므로, 상기의 도어라이너 및 선반부위로 흘러 들어간 분말수지는 도어라이너 및 선반이 일체로 형성되어 경화되므로, 도 5b와 같은 본 발명에 의한 일체형 선반의 좌우대칭 형상(15)이 금형에 의해 제작된다.Since the mold space of the integrated door shelf is made of the door liner and the shelf part, the powder resin flowed into the door liner and the shelf part is hardened by integrally forming the door liner and the shelf, according to the present invention as shown in FIG. The left and right symmetrical shapes 15 of the integrated shelf are produced by the mold.

상기의 금형에 의해 일체형 좌우대칭 선반 (15)이 제작되면, 여러단의 금형을 하나씩 제거한다. 그런 다음, 도 5c와 같이 좌우대칭되는 일체형 선반(15)의 중심을 센터라인을 기준으로 절단하여 목표한 도어라이너(11a) 및 선반(11b)을 일체로 제조하게 된다.When the integrated left-right symmetric shelf 15 is manufactured by the above-mentioned metal mold | die, the metal mold | die of several steps is removed one by one. Then, as shown in FIG. 5C, the centers of the unitary shelves 15 which are symmetrically symmetrically are cut based on the center line to integrally manufacture the target door liner 11a and the shelf 11b.

상기와 같은 제조 방법을 로테이션 몰딩법이라 명명한다.Such a manufacturing method is called a rotation molding method.

이상에서 설명한 바와 같이, 본 발명에 의한 냉장고의 일체형 도어선반의 제조방법은 냉장고의 도어 뒷면에 설치되는 도어라이너와, 그 도어라이너와 결합되는 도어선반을 일체로 성형함에 있어서, 로테이션 몰딩방법을 사용하므로, 작업공수가 줄어들고, 도어선반의 탈거 또는 깨짐등의 불량요인을 제거하여 비용을 절감시키는 효과가 있다.As described above, the manufacturing method of the integrated door shelf of the refrigerator according to the present invention uses a rotation molding method in integrally molding the door liner installed on the back of the door of the refrigerator and the door shelf coupled to the door liner. Therefore, the work maneuver is reduced, there is an effect of reducing the cost by removing the defective factors such as the removal or cracking of the door shelf.
