In the third station, the compression molding apparatus having the press device is the glass gove. Press to form a glass product. In the fifth, seventh and ninth stations, cooling air is injected into the molded glass product through a cooling device to cool the glass product. In the 11th, 2nd and 4th stations, natural cooling of the glass product is performed. You lose. In the sixth station, the molded and cooled glass products are taken out from the bottom mold and transferred to the post process, and the eighth and tenth stations pass with the bottom mold empty.

도 2 및 도 3은 각각 종래의 유리제품압축성형장치용 냉각장치의 종단면도 및 평면도이다. 중심선을 기준으로 도면의 좌측 및 우측영역에는 유리제품의 장변부 및 단변부를 각각 도시하였다. 이들 도면에 도시된 바와 같이, 턴테이블(21)상에 적치된 저부몰드(22)내에는 압축성형장치에 의해 성형된 유리제품(20)이 수용되어 있으며, 본 냉각장치(101)는, 유리제품압축성형장치의 제5 및 제7스테이션에 각각 승강가능하도록 설치되어 성형된 유리제품(20)의 내측연부를 향하여 냉각공기를 분사하게 된다.2 and 3 are a longitudinal sectional view and a plan view, respectively, of a conventional cooling device for glass compression molding apparatus. On the left and right sides of the drawing, the long side and the short side of the glass product are respectively shown based on the center line. As shown in these figures, the glass mold 20 formed by the compression molding apparatus is accommodated in the bottom mold 22 placed on the turntable 21. The cooling apparatus 101 is a glass article. Installed in the fifth and seventh stations of the compression molding apparatus, the cooling air is sprayed toward the inner edge of the molded glass article 20.

이하에서는 첨부된 도면을 참조하여 본 발명에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

본 발명에 따른 유리제품압축성형장치용 냉각장치는 유리제품압축성형장치의 제5스테이션 및 제7스테이션에 각각 설치되어 유리제품의 내측연부를 냉각한다.The cooling apparatus for glass product compression molding apparatus according to the present invention is installed in the fifth station and the seventh station of the glass product compression molding device, respectively, to cool the inner edge of the glass product.

도 4 및 도 5는 각각 본 발명에 따른 유리제품압축성형장치용 냉각장치의 종단면도 및 평면도이고, 도 6은 도 4의 격벽판의 확대단면도로서, 도면의 중심선을 기준으로 좌측 및 우측에는 각각 유리제품의 장변부 및 단변부를 도시하였다. 이들 도면에 도시된 바와 같이, 본 발명에 따른 유리제품압축성형장치용 냉각장치(1)는, 유리제품압축성형장치의 제5 및 제7스테이션의 상부영역으로부터 하향연장되도록 설치되어 냉각공기를 안내하는 덕트부재(3)와, 덕트부재(3)의 말단에 결합되는 상부판(5)과, 상부판(5)의 하측에 소정 이격배치되는 하부판(7)과, 상부판(5)과 하부판(7)사이에 제1토출부(10) 및 제2토출부(12)가 형성되도록 설치되는 격벽판(9)을 가진다.4 and 5 are longitudinal cross-sectional views and plan views, respectively, of the cooling apparatus for a glass product compression molding apparatus according to the present invention, and FIG. 6 is an enlarged cross-sectional view of the partition plate of FIG. The long side and the short side of the glass article are shown. As shown in these figures, the cooling apparatus 1 for glass compression molding apparatus according to the present invention is installed to extend downward from the upper regions of the fifth and seventh stations of the glass compression molding apparatus to guide cooling air. The duct member 3, the upper plate 5 coupled to the end of the duct member 3, the lower plate 7 spaced apart from the upper plate 5 by a predetermined distance, and the upper plate 5 and the lower plate. It has a partition plate 9 provided so that the 1st discharge part 10 and the 2nd discharge part 12 may be formed between (7).

상부판(5)의 중앙영역에는 덕트부재(3)로부터 공기가 유입될 수 있도록 판면을 관통하여 공기유입개구(11)가 형성되어 있으며, 격벽판(9)에는 판면을 관통하여 다수의 관통공(19)이 형성되어 있다. 이들 관통공(19)은 모두 외측으로 하향경사각을 가지고 형성되어 있으며, 경사각은 25~35도를 가지는 것이 바람직하며 본 실시예에서는 30도로 구성하였다. 그리고, 관통공(19)의 크기는 유리제품(20)의 크기, 덕트부재(3)를 통하여 공급되는 공기의 압력 등을 포함한 여러 가지 요인을 고려하여 결정된다.An air inlet opening 11 is formed in the central region of the upper plate 5 so as to allow air to flow from the duct member 3, and the partition plate 9 penetrates the plate surface to form a plurality of through holes. (19) is formed. All of the through holes 19 are formed to have a downward inclination angle to the outside, and the inclination angle is preferably 25 to 35 degrees, and is configured in this embodiment to 30 degrees. In addition, the size of the through hole 19 is determined in consideration of various factors including the size of the glass product 20, the pressure of air supplied through the duct member 3, and the like.

격벽판(9)은 벽두께가 두꺼운 유리제품(20)의 상부영역에 공기가 상대적으로 많이 분사될 수 있도록 하부판(7)에 인접되도록 배치된다. 즉, 제1토출부(10) 및 제2토출부(12)를 통하여 토출되는 공기가 적절히 분배될 수 있도록 격벽판(9)은, 상부판(5)과 하부판(7)사이의 거리에 대해 격벽판(9)과 상부판(5)과의 거리가 60%이상이 되게 배치되어 있다.The partition plate 9 is arranged to be adjacent to the lower plate 7 so that a large amount of air can be injected into the upper region of the glass product 20 having a thick wall thickness. That is, the partition plate 9 has a distance between the upper plate 5 and the lower plate 7 so that the air discharged through the first discharge portion 10 and the second discharge portion 12 can be properly distributed. It is arrange | positioned so that the distance of the partition plate 9 and the upper plate 5 may be 60% or more.

한편, 상부판(5)과 격벽판(9)과 하부판(7)은 모두 사각 판상부재로 형성되며, 이들의 각 변의 중앙영역에는 유리제품(20)의 중앙영역으로부터 소정의 이격거리를 두도록 내향만곡부(13,15,17)가 각각 형성되어 있다. 이들의 각 변의 길이는 유리제품(20)의 내벽면과 일정한 간격이 유지될 수 있도록 유리제품(20)의 곡률을 감안하여 일정폭으로 축소된다.On the other hand, the upper plate (5), partition plate (9) and lower plate (7) are all formed in a rectangular plate-like member, inwardly so that a predetermined distance from the central region of the glass product 20 in the central region of each side thereof Curved portions 13, 15 and 17 are formed, respectively. The length of each side thereof is reduced to a certain width in consideration of the curvature of the glass product 20 so that a constant distance from the inner wall surface of the glass product 20 can be maintained.

이러한 구성에 의하여, 제3스테이션에서 성형된 유리제품(20)이 제5스테이션에 도달하게 되면, 도시 않은 승강구동수단에 의해 덕트부재(3)는 도 4에 도시된 바와 같이, 하강하게 된다. 그러면, 덕트부재(3)를 통하여 냉각공기가 제1토출부(10) 및 제2토출부(12)를 통하여 유리제품(20)의 내측연부를 향하여 분사된다. 이 때, 제5스테이션에 공급되는 공기의 압력은 유리제품(20)의 성형직후로 온도가 비교적 높기 때문에 유리의 흐름정도를 고려하여 상대적으로 낮은 공기압력이 유지되도록 한다.By this configuration, when the glass product 20 formed in the third station reaches the fifth station, the duct member 3 is lowered by the lifting driving means (not shown), as shown in FIG. Then, the cooling air is injected toward the inner edge of the glass product 20 through the first discharge portion 10 and the second discharge portion 12 through the duct member (3). At this time, since the pressure of the air supplied to the fifth station is relatively high immediately after the molding of the glass product 20, the relatively low air pressure is maintained in consideration of the flow rate of the glass.

다음, 턴테이블(21)의 회전에 따라 유리제품(20)은 제7스테이션으로 이동하게 되고, 제5스테이션과 마찬가지로 덕트부재(3)가 하강하게 된다. 이 때, 덕트부재(3)를 통하여 공급되는 공기의 압력은, 제5스테이션에 비해 상대적으로 높은 압력이 유지되도록 한다.Next, as the turntable 21 rotates, the glass product 20 moves to the seventh station, and the duct member 3 descends as in the fifth station. At this time, the pressure of the air supplied through the duct member 3 is maintained to be relatively high pressure compared to the fifth station.

전술 및 도시한 실시예에서는, 공기분배수단으로 격벽판을 구성하여 설명하고 있지만, 상부판과 하부판사이에 형성되는 공기토출구영역에 제1토출부 및 제2토출부가 형성되도록 가이드부재를 설치할 수도 있다.In the above-described and illustrated embodiments, the partition plate is formed as an air distribution means, but the guide member may be provided such that the first discharge portion and the second discharge portion are formed in the air discharge port region formed between the upper plate and the lower plate. .

전술 및 도시한 예에서는 유리제품으로 음극선관용 펀넬유리를 예를들어 설명하고 있지만, 음극선관용 패널유리의 냉각에 본 발명의 구성을 적용하면 동일한 효과를 얻을 수 있음은 물론이다.In the above-described and illustrated examples, the glass product is described as an example of the funnel glass for the cathode ray tube, but the same effect can be obtained by applying the configuration of the present invention to the cooling of the panel glass for the cathode ray tube.

이상 설명한 바와 같이, 본 발명에 따르면, 공기량을 감소시키지 않으면서 유리제품에 분사되는 공기에 의해 유리제품의 둘레면의 형상이 변형되는 것을 억제시킬 수 있으며, 유리제품의 벽두께에 대응하여 냉각공기의 분사량을 달리함으로써 균일한 냉각효과를 얻을 수 있는 유리제품압축성형장치용 냉각장치가 제공된다.As described above, according to the present invention, the shape of the circumferential surface of the glass product can be suppressed from being deformed by the air injected into the glass product without reducing the amount of air, and the cooling air corresponds to the wall thickness of the glass product. There is provided a cooling apparatus for a glass product compression molding apparatus which can obtain a uniform cooling effect by varying the injection amount of.
