Description

납물의 배출량이 균일한 런너블럭Runner block with uniform discharge
본 발명은 납물의 배출량이 균일한 런너블럭에 관한 것으로, 보다 상세하게는 스트랩을 성형하기 위한 캐스트-온-스트랩 몰드에 납물을 공급하기 위한 런너블럭에 있어 납물유동채널에 납물이 균등한 양으로 배출되도록 함으로써 몰드공동에 채워지는 납물의 충전속도를 일정하게 유지할 수 있도록 하기 위한 런너블럭에 관한 것이다.The present invention relates to a runner block having a uniform discharge amount of lead, and more particularly, to a runner block for supplying lead to a cast-on-strap mold for molding a strap in an amount of lead in an lead flow channel. The present invention relates to a runner block for maintaining a constant filling rate of lead to be filled in a mold cavity.
일반적으로, 연축전지(납배터리)는 캐스트-온-스트랩(COS; Cast-On-Strap) 몰드에 의해 제조되고 있으며, 상기 캐스트-온-스트랩 몰드(이하 '몰드'라 한다)의 양측에는 용융된 납(Pb) 또는 납 합금, 즉 납물을 공급하기 위한 런너블럭(피드블럭이라고도 함)이 형성된다.In general, lead-acid batteries (lead batteries) are manufactured by cast-on-strap (COS) molds and are melted on both sides of the cast-on-strap molds (hereinafter referred to as 'molds'). Lead (Pb) or a lead alloy, that is, a runner block (also called a feed block) for supplying a lead is formed.
이처럼 상기 런너블럭을 통해 몰드에 공급되는 납물은 일단 런너블럭 상부에 형성된 납물유동채널로 배출되었다가 둑을 넘쳐 몰드의 상부에 형성된 몰드공동(空洞)에 채워진 다음 납물의 공급을 차단하게 되면 몰드공동 내의 초과된 납은 역류배출되고, 남은 납물은 천천히 냉각되면서 클램핑된 상태의 배터리 셀 플레이트의 러그에 스트랩을 캐스팅하게 된다. As such, the lead supplied to the mold through the runner block is discharged into the lead flow channel formed at the top of the runner block and filled in the mold cavity formed at the upper part of the mold, and then the supply of the lead is blocked. Excess lead in the back is discharged and the remaining lead slowly cools and casts the strap to the lugs of the clamped battery cell plate.
상기 납물을 공급하는 런너블럭의 온도는 약 440℃에 이르고 납물을 공급받는 몰드의 온도는 90~140℃여서 런너블럭으로부터 몰드로 공급되는 납물은 유입시간과 유입량에 따라 굳는 속도와 두께에 차이가 발생하게 된다.The temperature of the runner block for supplying the lead reaches about 440 ° C., and the temperature of the mold for receiving the lead is 90 to 140 ° C., so that the lead from the runner block to the mold varies in speed and thickness depending on inflow time and inflow. Will occur.
즉 몰드공동으로 제일 먼저 유입된 납물과 맨 나중에 유입되는 납물은 다른 냉각속도에 의해 스트랩 내부에 수지상정(dendrite)에 의한 서로 다른 결정조직이 형성하게 되고, 이는 결과적으로 제품 형상에 변형이 생기게 하거나 각 스트랩의 무게에 편차를 발생하게 하고, 균열 등에 취약한 상태가 되도록 하여 결국 상품성 저하로 이어진다.In other words, the first lead in the mold cavity and the last lead in the lead form different densities due to dendrite inside the strap due to different cooling rates, resulting in deformation of the product shape. Deviation in the weight of the straps, and vulnerable to cracks, etc., eventually leads to a deterioration of the merchandise.
종래의 런너블럭은 납물을 공급하기 위한 관로가 런너블럭의 내부에 길이방향으로 하나만 형성되는 구조이고, 상기 납물공급관로에 다수개의 납물배출공이 수직으로 연통되되, 상기 납물배출공의 직경은 모두 동일한 구조여서 결국 펌프의 펌핑압력에 의해 납물이 배출됨에 있어 납물공급관로의 종단(終端)에 형성된 납물배출공을 통해 배출되는 납물의 배출량이 가장 많고, 선단(先端)에 형성된 납물배출공을 통해 배출되는 납물의 배출량이 가장 적어 결국 각각의 납물배출공을 통해 납물유동채널로 배출되는 납물의 배출량이 모두 다를 수밖에 없는 것이다.The conventional runner block has a structure in which only one conduit for supplying lead is formed in the lengthwise direction of the runner block, and a plurality of lead discharge holes are vertically communicated with the lead supply pipe, and the diameters of the lead discharge holes are all the same. As a result, the lead is discharged by the pumping pressure of the pump, so the lead discharged through the lead discharge hole formed at the end of the lead supply line is the most discharged, and is discharged through the lead discharge hole formed at the front end. The amount of lead discharged is the lowest, so that the amount of lead discharged through the lead discharge channel into the lead flow channel is different.
이를 해결하기 위해 특허등록 제10-1090635호 "배터리 극판을 금속 스트랩 또는 포스트에 연결하기 위한 장치"의 도면에 도시된 바와 같이 납물공급관로를 두개로 나누고, 상기 나누어진 두개의 납물공급관로에 납물배출공들을 절반씩 나누어 연결되도록 함으로써 납물의 배출량을 좀더 균일하게 하기 위한 기술이 개시된 바 있다.To solve this problem, as shown in the drawing of Patent Registration No. 10-1090635 "A device for connecting the battery pole plate to a metal strap or a post", the lead supply line is divided into two, and the lead supply line is divided into two lead supply lines. A technique has been disclosed to make the discharge of the lead more evenly by splitting the discharge holes in half.
그러나 상기한 특허등록 제10-1090635호는 납물공급관로를 두 개로 나누어 형성함으로써 납물공급관로가 하나로 이루어진 것에 비해 좀더 균일한 납물의 배출은 가능하나, 두 개로 나누어진 납물공급관로 역시 상기 납물공급관로에 연통(
Figure PCTKR2013003757-appb-I000001
)된 납물배출공들의 직경은 동일한 상태여서 결과적으로 납물공급관로의 종단에 위치하는 납물배출공을 통해 배출되는 납물의 배출량은 가장 많고, 선단에 위치하는 납물배출공을 통해 배출되는 납물의 배출량은 가장 적은 상태가 될 수밖에 없다. However, the above-described patent registration No. 10-1090635 is formed by dividing the lead supply pipeline into two, so that it is possible to discharge a more uniform supply than the lead supply pipeline consists of one, but the lead supply pipeline divided into two also supply the supply pipeline Communicate in
Figure PCTKR2013003757-appb-I000001
) The diameters of the lead discharge holes are the same, so the amount of lead discharged through the lead discharge hole located at the end of the lead supply line is the highest, and the amount of lead discharged through the lead discharge hole located at the end is It must be in the least state.
이는 납물유동채널에 채워지는 납물의 수위(水位)를 일정하게 형성할 수 없고 또 몰드공동에 채워지는 납물의 충전(
Figure PCTKR2013003757-appb-I000002
)속도에 차이를 발생하게 되므로 결국 스트랩의 각 부분의 냉각속도가 달라지면서 스트랩의 결정조직에 미세한 차이를 발생하게 되고, 상기한 바와 같은 스트랩 결정조직들의 차이는 내구성을 취약하게 하여 상품성을 하락시키는 원인이 되는 단점을 갖는다.This can not form a constant level of lead filled in the lead flow channel and the filling of lead filled in the mold cavity (
Figure PCTKR2013003757-appb-I000002
As a result of the difference in speed, the cooling rate of each part of the strap is changed, resulting in a slight difference in the crystal structure of the strap. It has a disadvantage that causes it.
본 발명은 상기한 바와 종래의 런너블럭이 갖는 문제점을 해결하기 위해서 다양한 연구를 진행한 결과, 납물공급관로에 연통된 납물배출공들 중 종단에 위치하는 납물배출공과 선단에 위치하는 납물배출공과의 직경의 크기를 차별화함으로써 이를 해결할 수 있도록 하였다.According to the present invention, various researches have been conducted to solve the problems of the above-described runner block and the present invention. Among the lead discharge holes connected to the lead supply line, the present invention has a lead discharge hole positioned at the end and a lead discharge hole positioned at the end. This can be solved by differentiating the size of the diameter.
즉 납물공급관로에 연통된 납물배출공들 중 종단에 위치하여 가장 많은 양의 납물이 배출되는 납물배출공의 직경의 크기는 가장 작게 형성하고, 선단에 위치하여 가장 적은 양의 납물이 배출되는 납물배출공과의 직경의 크기는 가장 크게 형성함으로써 결과적으로 납물배출공을 통해 배출되는 납물의 양을 최대한 균일화할 수 있도록 함을 특징으로 한다.That is, the size of the diameter of the lead discharge hole which is located at the end of the lead discharge holes connected to the lead supply pipeline to discharge the largest amount of lead is formed to be the smallest, and the lead which discharges the smallest amount of lead is located at the tip. The diameter of the discharge hole is formed to have the largest size, and as a result, the amount of lead discharged through the lead discharge hole can be as uniform as possible.
상기와 같은 본 발명의 효과로는 런너블럭의 납물유동채널에 납물이 채워짐에 있어 모든 납물배출공으로 부터 납물이 균등한 양으로 배출되도록 함으로써 몰드공동에 채워지는 납물의 충전속도를 균일하게 할 수 있으며, 이로 인해 각 스트랩의 냉각속도를 균일하게 하여 결정조직 역시 균일하게 함으로써 배터리 제품의 상품성을 높일 수 있는 매우 유용한 발명인 것이다.According to the effects of the present invention as described above, in the lead flow channel of the runner block is filled in the lead by the discharge of the lead in the same amount from all the lead discharge holes can be uniformly filling rate of the lead filled in the mold cavity and Therefore, it is a very useful invention that can increase the commercialization of the battery product by making the cooling rate of each strap uniform, thereby making the crystal structure uniform.

본 발명은 납물유입관로(32)를 통해 공급된 납물을 납물유동채널(23,23')로 공급하기 위한 내측관로(24,24') 및 외측관로(26,26')가 런너블럭 내부에 길이방향으로 수평으로 형성되고, 상기 내측관로(24,24') 및 외측관로(26,26')에는 다수개의 납물배출공(25,25')이 수직으로 연통되도록 형성되되, 상기 납물배출공(25,25')들 중 내측관로(24,24') 및 외측관로(26,26') 종단에 위치하는 납물배출공의 직경의 크기는 가장 작게 형성하고, 내측관로(24,24') 및 외측관로(26,26') 선단에 위치하는 납물배출공과의 직경의 크기는 가장 크게 형성함으로써 결과적으로 납물배출공(25,25')을 통해 배출되는 납물의 양을 최대한 균일화할 수 있도록 한다.According to the present invention, the inner conduits 24 and 24 'and the outer conduits 26 and 26' for supplying the consumables supplied through the inflow conduit 32 to the conduit flow channels 23 and 23 'are provided inside the runner block. It is formed horizontally in the longitudinal direction, and the plurality of lead discharge holes (25, 25 ') are formed in vertical communication with the inner pipe line (24, 24') and the outer pipe line (26, 26 '), Among the (25, 25 '), the diameter of the lead discharge hole located at the end of the inner conduit (24, 24') and the outer conduit (26, 26 ') is formed the smallest, the inner conduit (24, 24') And the diameter of the lead discharge hole located at the tip of the outer pipe 26, 26 'is formed to be the largest so that the amount of lead discharged through the lead discharge holes 25, 25' can be as uniform as possible. .
이는 다시 설명하면 내측관로(24,24') 및 외측관로(26,26')에 형성되는 납물배출공(25,25')들의 직경 크기가 내측관로(24,24')와 외측관로(26,26') 선단에서 종단으로 갈수록 점차 작아지도록 형성함을 의미한다.In other words, the diameters of the lead discharge holes 25 and 25 'formed in the inner and outer pipes 24 and 24' and the outer and outer pipes 26 and 26 'are 26 and 26, respectively. , 26 ') means to form gradually smaller from the end to the end.
이때 내측관로(24,24') 및 외측관로(26,26')에서 선단은 납물유입관로(32)에 가까운 쪽을 의미하며, 종단은 납물유입관로(32)에서 먼쪽을 의미한다.At this time, the tip in the inner pipe line (24, 24 ') and the outer pipe (26, 26') means the side closer to the lead inlet pipe 32, the end means the far side from the lead inlet pipe (32).
따라서 본 발명은 종래의 경우 가장 많은 양의 납물이 배출되던 내측관로(24,24') 및 외측관로(26,26')의 종단에 위치하는 납물배출공 직경은 가장 작게제조함으로써 배출되는 납물의 양은 최소상태가 되도록 하고, 반대로 종래 가장 적은 양의 납물이 배출되던 내측관로(24,24') 및 외측관로(26,26')의 선단에 위치하는 납물배출공 직경은 가장 크게 제조함으로써 배출되는 납물의 양이 오히려 최대가 되어 결국 납물유동채널(23,23')에 납물의 수위를 일정하게 유지할 수 있으며, 또 몰드공동(15, 15')으로 채워지는 납물의 충전속도도 균일하게 되는 것이다.Therefore, in the present invention, the diameter of the lead discharge hole located at the end of the inner pipe line 24 and 24 'and the outer pipe line 26 and 26' in which the largest amount of the lead is discharged in the conventional case is the smallest. The amount is kept to the minimum state, and conversely, the diameter of the lead discharge hole located at the leading end of the inner pipe line 24 and 24 'and the outer pipe line 26 and 26' where the smallest amount of the lead is discharged is discharged by manufacturing the largest amount. The amount of lead is rather maximal, so that the level of the lead can be kept constant in the lead flow channels 23 and 23 ', and the filling rate of the lead filled with the mold cavities 15 and 15' is also uniform. .
이처럼 전체 납물배출공(25,25')의 직경크기를 선단과 종단의 위치에 따라 다르게 적용함으로써 본 발명은 전체적으로 납물배출량을 균일하게 할 수 있으며, 이는 결국 몰드(10)의 몰드공동(15,15')에 채워지는 납물의 충전속도도 균일하게 할 수 있고, 동시에 스트랩의 각 부분의 냉각속도 역시 균일해짐을 의미하므로 결과적으로 스트랩의 결정조직에 차이가 줄어들면서 내구성이 증대되어 배터리의 상품성을 향상시킬 수 있는 것이다.In this way, by applying different diameter sizes of the entire lead discharge holes 25 and 25 'according to the position of the front end and the end, the present invention can make the lead discharge amount uniform throughout, which leads to the mold cavity 15 of the mold 10. 15 ') also allows the charging speed of the lead to be uniform, and at the same time the cooling rate of each part of the strap is also uniform, resulting in less durability and increased durability of the battery due to less variation in the crystal structure of the strap. It can be improved.
또한 상기 내측관로(24, 24') 및 외측관로(26, 26')에 형성되는 납물배출공(25, 25')은 2~3개가 한 쌍이 되어 분산 배치되도록 구성하되, 상기 각 쌍을 이루는 납물배출공(25, 25')들은 몰드공동(15, 15')의 위어부(11, 11')와 일치하도록 배치함이 바람직하다. In addition, the lead discharge holes (25, 25 ') formed in the inner pipe line (24, 24') and the outer pipe (26, 26 ') is configured to be distributed in pairs of two to three, each forming a pair The lead discharge holes 25 and 25 'are preferably arranged to coincide with the weir portions 11 and 11' of the mold cavities 15 and 15 '.
상술 한 바와 같이 본 발명은 비록 한정된 실시예들에 의해 설명되었으나, 본 발명은 이것에 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능하다 할 것이다.As described above, although the present invention has been described by way of limited embodiments, the present invention is not limited thereto, and the technical concept of the present invention and the following will be described by those skilled in the art to which the present invention pertains. Various modifications and variations will be possible within the scope of the appended claims.
납물유동채널에 납물이 균등한 양으로 배출되도록 함으로써 몰드공동에 채워지는 납물의 충전속도를 일정하게 유지할 수 있도록 하는 런너블럭을 제공함으로써 각 스트랩의 냉각속도를 균일하게 하여 결정조직 역시 균일하게 함으로써 배터리 제품의 상품성을 높일 수 있는 것이다.By providing a runner block that keeps the charge rate of lead filling in the mold cavity constant by discharging equal amount of lead in the lead flow channel, the cooling rate of each strap is uniform and the crystal structure is also uniform. It can increase the product's marketability.
