Description

배터리용 캐스트 온 스트랩 몰드의 순환식 냉각 구조Cyclic cooling structure of cast on strap mold for battery
본 발명은 배터리용 캐스트 온 스트랩 몰드의 순환식 냉각 구조에 관한 것으로, 보다 상세하게는 상부에 몰드 공동을 구비하는 몰드의 내부에 냉각수 관로를 형성하되 냉각수가 몰드 내부에서 가장 바람직한 순환구조를 가질 수 있도록 냉각수 관로를 형성함으로써 몰드 냉각이 신속하게 이루어지도록 하고, 이로 인해 배터리 생산수율을 극대화시킬 수 있는 배터리용 캐스트 온 스트랩 몰드의 순환식 냉각 구조에 관한 것이다.The present invention relates to a circulating cooling structure of a cast-on-strap mold for a battery, and more particularly, to form a cooling water conduit inside a mold having a mold cavity thereon, while the cooling water can have a most desirable circulation structure in the mold. The present invention relates to a circulating cooling structure of a cast-on-strap mold for a battery, in which mold cooling is performed quickly by forming a coolant pipe so as to maximize the battery production yield.
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 런너블럭이 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 lead alloy, that is, a runner block for supplying lead materials is formed.
이처럼 상기 런너블럭을 통해 공급되는 납물은 몰드의 상부에 형성된 몰드 공동(空洞)에 채워져 스트랩을 형성하게 된다.In this way, the lead supplied through the runner block is filled in the mold cavity formed on the upper part of the mold to form a strap.
그런데 상기 스트랩을 형성함에 있어 종래의 몰드는 런너블럭으로 부터 공급되는 납물이 보를 넘쳐 몰드공동에 채워진 다음 납물의 공급을 차단하게 되면 천천히 냉각되면서 클램핑된 상태의 배터리 셀 플레이트의 러그에 스트랩을 캐스팅하게 된다.However, in forming the strap, the conventional mold casts the strap to the lug of the battery cell plate in a clamped state when the lead supplied from the runner block overflows the beam to fill the mold cavity and then block the supply of the lead to cool slowly. do.
이때 납물을 공급하는 런너블럭의 온도는 약 440℃에 이르고 납물을 공급받는 몰드의 온도는 90~140℃여서 몰드를 신속하게 냉각시키지 않고는 캐비티를 배출시킬 수 없는 구조여서 상기 몰드의 냉각속도에 따라 제품의 품질은 물론 캐비티의 배출시간이 늦어질수록 생산성은 필연적으로 낮아질 수밖에 없어 몰드의 냉각효율의 향상은 배터리 생산수율과 직결되는 것이어서 매우 중요한 요소라 할 것이다.At this time, 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 cavity cannot be discharged without rapidly cooling the mold. Therefore, as the product quality and the cavity discharge time are delayed, the productivity will inevitably be lowered. Therefore, the improvement of the cooling efficiency of the mold is directly related to the yield of the battery, which is a very important factor.
종래에도 몰드를 신속하게 냉각하기 위해 다양한 냉각수단이 강구되고 있으며, 참고로 도 1 내지 도 3에 도시한 바와 같은 종래의 몰드(10)의 냉각 구조는 다음과 같다. 즉 상기 종래의 몰드(10) 내부에는 길이방향으로 상부와 하부를 지나는 냉각수 관로가 형성되고, 상부에는 스트랩을 성형하기 위한 몰드공동(13)이 형성되는데, 이때 하부를 지나는 냉각수 관로는 냉각수가 들어오는 냉각수 유입공(11)이며, 상부를 지나는 냉각관로는 냉각수가 배출되는 냉각수 배출공(12)이다. In the related art, various cooling means have been devised to quickly cool the mold, and the cooling structure of the conventional mold 10 as shown in FIGS. 1 to 3 is as follows. That is, the conventional mold 10 inside the cooling water pipe passing through the upper and lower in the longitudinal direction is formed, a mold cavity 13 for forming the strap is formed on the upper, wherein the cooling water pipe passing through the lower enters the cooling water The cooling water inlet hole 11 and the cooling pipe passage passing through the upper portion is a cooling water discharge hole 12 through which the cooling water is discharged.
상기 냉각수 유입공(11)과 냉각수 배출공(12)은 수직으로 형성되는 연결공(10a)에 의해 연결되어 서로 통하게 되는데, 이때 상기 각각의 냉각수 유입공(11)과 냉각수 배출공(12)의 양측에는 냉각효과를 높이기 위하여 보조냉각공(14,15)이 몰드(10) 내부에 수평으로 형성된다.The cooling water inlet 11 and the cooling water outlet 12 are connected to each other by a connection hole 10a which is formed vertically, wherein each of the cooling water inlet 11 and the cooling water outlet 12 On both sides, auxiliary cooling holes 14 and 15 are horizontally formed inside the mold 10 to increase the cooling effect.

배터리 캐스트 온 스트랩용 몰드(Mould for a battery cast on strap) - 특허출원번호 제10-2012-7018887호 Mold for a battery cast on strap-Patent Application No. 10-2012-7018887
그러나 상기와 같은 냉각 구조를 갖는 종래의 몰드(10)의 문제는 냉각수 유입공(11)을 통해 유입된 냉각수가 연결공(10a)을 통해 냉각수 배출공(12)으로 곧바로 빠져나가 버리게 되어 냉각 효과가 현저히 떨어진다는 것이다. However, the problem of the conventional mold 10 having the cooling structure as described above is that the cooling water introduced through the cooling water inlet 11 is immediately exited to the cooling water outlet 12 through the connection hole (10a), the cooling effect Is a significant drop.
물론 냉각 표면적을 넓혀 냉각 효율을 보다 좋게 하기 위하여 냉각수 유입공(11)과 냉각수 배출공(12)의 양측에 형성한 보조냉각공(14,15)이 있긴 하나, 상기 보조냉각공(14,15)으로 유입된 냉각수는 한번 유입되면 순환이 곤란하여 몰드(10)를 냉각함에 있어 그다지 효과적이지 못하다.Of course, there are auxiliary cooling holes 14 and 15 formed at both sides of the cooling water inlet 11 and the cooling water outlet 12 to increase the cooling surface area to improve cooling efficiency. Cooling water introduced into the) is difficult to circulate once it is introduced, so it is not very effective in cooling the mold 10.
즉 상기 보조냉각공(14,15)으로 유입된 냉각수는 몰드(10)가 런너블럭으로 부터 공급되는 납물에 의해 가열되어 100℃가 넘어야만 끓게 되면서 밖으로 배출가능한 구조이며, 이마저도 보조냉각공(14,15)으로 유입될려는 냉각수들과 부딪쳐 와류를 형성하게 되고, 심지어는 냉각수가 끓으면서 발생하는 기포에 의해서도 배출에 방해를 받게 되는 것이다.That is, the cooling water introduced into the sub-cooling holes 14 and 15 is a structure in which the mold 10 is heated by the lead supplied from the runner block to be boiled only after the temperature exceeds 100 ° C., and even the sub-cooling holes 14 are removed. 15) they collide with the cooling water to be introduced into the vortex, forming a vortex, and even the air bubbles generated by boiling the cooling water are disturbed by the discharge.
이처럼 가열된 상태의 냉각수들이 보조냉각공(14,15) 속에 정체되어 쉽게 배출되지 못하고 머무른다는 것은 결국 효율적인 냉각이 이루어지지 못함을 의미하고, 효율적이지 못한 몰드(10)의 냉각은 그만큼 제품 제조시간의 지연을 의미하는 것이어서 심각한 생산성 하락으로 이어지는 것이다.As the coolant in the heated state stagnates in the subcooling holes 14 and 15 and is not easily discharged, it means that the cooling is not performed efficiently, and the cooling of the mold 10 is inefficient. This means a delay in productivity, which leads to a serious drop in productivity.
상기한 바와 같은 종래 캐스트-온-스트랩 몰드가 갖는 단점을 해결하기 위한 본 발명은 몰드 내부에 길이방향으로 하부에는 냉각수 유입공을 형성하고, 상부에는 냉각수 배출공을 형성하고, 상기 냉각수 유입공과 냉각수 배출공은 다수개의 냉각수 순환관에 의해 서로 통하도록 연결되도록 하되, 상기 냉각수 순환관은 냉각수 유입공으로 부터 시작되어 수평 또는 경사지게 측방향으로 연장되었다가 안쪽으로 꺾여 냉각수 유입공 상부에 위치한 냉각수 배출공에 다시 연결되도록 구성됨을 특징으로 한다.The present invention for solving the disadvantages of the conventional cast-on-strap mold as described above to form a cooling water inlet hole in the lower portion in the longitudinal direction in the mold, the cooling water discharge hole in the upper portion, the cooling water inlet hole and the cooling water The discharge holes are connected to each other by a plurality of cooling water circulation pipes, the cooling water circulation pipes extending laterally horizontally or inclined starting from the cooling water inlet holes and then bent inward to the cooling water discharge holes located above the cooling water inlet holes. And configured to be reconnected.
상기 냉각수 순환관은 냉각수 유입공과 냉각수 배출공의 양쪽에 한 쌍으로 형성되도록 구성됨을 특징으로 한다.The cooling water circulation pipe is characterized in that it is configured to be formed in a pair in both the cooling water inlet hole and the cooling water discharge hole.
상기 냉각수 순환관은 단면으로 보아 "ㄷ"자 형상으로 이루어짐을 특징으로 한다. The cooling water circulation pipe is characterized in that it is made of a "C" shape in cross section.
상기와 같은 본 발명의 효과로는 냉각수 순환관에 의해 상당한 냉각 표면적을 가지면서도 상기 냉각수 순환관 내부에 냉각수가 고여있거나, 정체되지 않도록 함으로써 냉각 효과를 극대화할 수 있도록 한다.The effects of the present invention as described above to have a substantial cooling surface area by the cooling water circulation pipe, but to maximize the cooling effect by preventing the cooling water is accumulated or stagnated inside the cooling water circulation pipe.
또한 본 발명은 냉각수가 유입되는 냉각수 유입공의 상부에 냉각수를 배출하기 위한 냉각수 배출공을 형성하되 상기 냉각수 유입공과 냉각수 배출공을 냉각수 순환관으로만 연결하여 온도가 높아지면 비중이 낮아지는 물의 특성을 이용하여 몰드가 가열되면 냉각수가 대류 되면서 자연스럽게 냉각수의 순환이 이루어지도록 하여 신속한 몰드의 냉각이 가능하게 된다.In addition, the present invention is to form a cooling water discharge hole for discharging the cooling water in the upper portion of the cooling water inlet hole in which the coolant is introduced, the connection of the cooling water inlet hole and the cooling water discharge hole only by the cooling water circulation pipe to increase the temperature characteristic of the water is low When the mold is heated by using the convection of the cooling water is naturally convection of the cooling water is made to enable rapid cooling of the mold.
이처럼 본 발명은 신속하고 안정적인 몰드 냉각으로 인한 제품의 품질 향상(스트랩의 균일한 결정조직)은 물론 스트랩 냉각대기 사이클을 종래 몰드에 비해 약 4초 정도를 줄여 엄청난 배터리 생산수율의 향상을 기대할 수 있는 매우 유용한 발명인 것이다.As such, the present invention can improve the product quality due to rapid and stable mold cooling (uniform crystal structure of the strap) as well as reduce the cooling cycle of the strap by about 4 seconds compared to the conventional mold, which can be expected to greatly increase the yield of battery production. It is a very useful invention.

본 발명의 실시예에 따른 배터리용 캐스트 온 스트랩 몰드의 순환식 냉각 구조는, 몰드(100) 본체 내부에 몰드(100)의 길이방향으로 하부에는 냉각수 유입공(110)이 형성되고, 상부에는 냉각수 배출공(120)이 형성되는 배터리용 캐스트 온 스트랩 몰드에 있어서, 상기 냉각수 유입공(110)과 냉각수 배출공(120)은 다수개의 냉각수 순환관(160)에 의해 서로 연통(
Figure PCTKR2013003768-appb-I000001
)되도록 하되, 상기 냉각수 순환관(160)은 냉각수 유입공(110)으로 부터 시작되어 수평 또는 경사지게 측방향으로 연장되었다가 안쪽으로 꺾여 냉각수 유입공(110) 상부에 위치한 냉각수 배출공(120)에 연결되도록 구성된다.In the circulating cooling structure of the cast-on-strap mold for a battery according to an embodiment of the present invention, a cooling water inlet hole 110 is formed in a lower portion of the mold 100 in the longitudinal direction of the mold 100, and a cooling water is formed at an upper portion thereof. In the cast-on-strap mold for the battery in which the discharge hole 120 is formed, the cooling water inlet hole 110 and the cooling water discharge hole 120 communicate with each other by a plurality of cooling water circulation pipes 160.

However, the coolant circulation pipe 160 starts from the coolant inlet 110 and extends laterally in a horizontal or inclined direction, and is then folded inward to the coolant outlet 120 located above the coolant inlet 110. It is configured to be connected.
상기 냉각수 순환관(160)은 냉각수 유입공(110)과 냉각수 배출공(120)의 양쪽에 단면으로 보아 "ㄷ" 형상으로 이루어져 냉각수 유입공(110)과 냉각수 배출공(120)을 서로 연결되도록 하는 구성이 냉각효율 및 제작의 용이성을 감안했을 때 가장 바람직하다. The coolant circulation pipe 160 is formed in a "c" shape in cross section at both sides of the coolant inlet 110 and the coolant outlet 120 to connect the coolant inlet 110 and the coolant outlet 120 to each other. The configuration is most preferable in view of the cooling efficiency and the ease of production.
이처럼 본 발명은 냉각수 유입공(110)을 통해 유입된 냉각수가 냉각수 순환관(160)을 통해 냉각수 배출공(120)으로 배출되면서 몰드(100)를 냉각하게 된다.As described above, the present invention cools the mold 100 while the coolant introduced through the coolant inlet 110 is discharged to the coolant discharge hole 120 through the coolant circulation pipe 160.
또한 상기 냉각수 순환관(160)은 냉각수 유입공(110)으로 부터 시작되어 도 5에 도시한 바와 같이 수평으로 측방향으로 연장되었다가 안쪽으로 꺾여 냉각수 유입공(110) 상부에 위치한 냉각수 배출공(120)에 다시 연결되는 구조여서 몰드(100) 내부에 상당한 냉각 표면적을 확보할 수 있는 구조이고, 이로 인해 냉각 효율을 좋아져 냉각속도를 빠르게 할 수 있다.In addition, the coolant circulation pipe 160 starts from the coolant inlet hole 110 and extends laterally horizontally as shown in FIG. 5, and is folded inward to form a coolant outlet hole located above the coolant inlet hole 110. 120 is a structure that can be secured to a considerable cooling surface area inside the mold 100 because it is connected to the back, thereby improving the cooling efficiency it is possible to increase the cooling rate.
도 8의 경우는 몰드 공동과 몰드 공동의 간격이 좁은 경우에 해당하는 구조로, 인접한 몰드 공동(130)의 간격이 좁을 경우 몰드 공동과 몰드 공동 사이에 냉각수 배출공(120)이 형성될 공간이 부족하여 몰드 공동(130) 사이로 냉각수 순환관(160)의 상부가 지나도록 하되 냉각수를 배출하기 위한 냉각수 배출공(120)은 냉각수 순환관(160)의 상부 보다 아래에 위치하도록 하므로써 몰드의 공간활용도를 높일 수 있도록 한 것이다.8 illustrates a structure corresponding to a case in which the gap between the mold cavity and the mold cavity is narrow. When the distance between the adjacent mold cavity 130 is narrow, a space in which the cooling water discharge hole 120 is to be formed is formed between the mold cavity and the mold cavity. Since the upper portion of the cooling water circulation pipe 160 passes between the mold cavity 130, the cooling water discharge hole 120 for discharging the cooling water is located below the upper portion of the cooling water circulation pipe 160 so that the space utilization of the mold It would be to increase.
이처럼 본 발명은 몰드(100)가 가열되면 냉각수의 비중이 낮아져 대류하는 원리를 이용해서 냉각수 유입공(110)과 냉각수 순환관(160), 냉각수 배출공(120)을 통해 냉각수의 자연스러운 순환을 유도함으로써 몰드(100)의 빠른 냉각과 균일한 냉각이 가능해지는 구조이다.As such, the present invention induces a natural circulation of the coolant through the coolant inlet hole 110, the coolant circulation pipe 160, and the coolant outlet hole 120 using the principle that the specific gravity of the coolant is convexized when the mold 100 is heated. As a result, the mold 100 can be rapidly cooled and uniformly cooled.
또 본 발명은 냉각수가 냉각수 관로 내에서 고이거나 정체되지 않도록 함으로써 신속하고 안정적인 몰드(100) 냉각으로 인한 스트랩이 균일한 결정조직을 갖게되고, 스트랩 냉각대기 시간, 즉 냉각사이클을 종래의 몰드에 비해 현저히 줄일 수 있어 배터리 생산수율의 비약적인 향상을 기대할 수 있게 된다.In addition, the present invention prevents the coolant from accumulating or stagnating in the coolant pipeline, so that the strap due to rapid and stable cooling of the mold 100 has a uniform crystal structure. Significantly reduced, it is possible to expect a dramatic improvement in battery production yield.
