본 발명은 납축전지 케이스 부품중의 하나인 메인커버를 성형시키는 납축전지 케이스성형용 금형에 관한 것으로, 더욱 상세하게는 벤트캡이 설치되는 나사홀을 성형시키는 스크류코어의 동력전달장치를 개선하여 성형동작시 작동이 불량해지는 것을 방지할 수 있게 한 납축전지 케이스 성형용 금형에 관한 것이다.The present invention relates to a lead-acid battery case molding mold for molding a main cover, which is one of the lead-acid battery case parts, and more particularly, to improve the power transmission device of the screw core for forming a screw hole in which the vent cap is installed. The present invention relates to a mold for forming a lead acid battery case, which can prevent operation from being poor.

일반적으로 납축전지 케이스는 첨부된 도면 도 1 에 도시되는 바와 같이, 다수의 셀(10)로 구획되고 각 셀의 내부에 전극과 전해액이 담겨지는 컨테이너(1)와; 컨테이너의 상부에 설치되고 벤트캡(4)이 설치되는 나사홀(20)과 컨테이너 내부로부터 발생되는 가스를 납축전지 외부로 배출시키는 가스배출로(21)를 구비하는 메인커버(2)와; 메인커버의 일측에 설치되는 파이널커버(3)로 구성된다.Generally, a lead acid battery case includes a container 1 partitioned into a plurality of cells 10 and containing electrodes and electrolytes in each cell, as shown in FIG. 1; A main cover (2) having a screw hole (20) installed at the top of the container and having a vent cap (4) installed therein, and a gas discharge passage (21) for discharging gas generated from the inside of the container to the outside of the lead storage battery; It consists of a final cover (3) installed on one side of the main cover.

첨부된 도면 도 2 는 종래의 금형을 발췌 도시한 단면도이고, 도 3 은 종래 금형에서 스크류코어를 발췌 도시한 사시도이다.2 is a cross-sectional view showing an extract of a conventional mold, Figure 3 is a perspective view showing an extract of a screw core in a conventional mold.

도 2 및 도 3 에 도시되는 바와 같이, 하금형(51)의 상측에 승강장치(55)에 의해 승강되는 상금형(52)이 설치되고, 하금형(51)의 저부에는 나사홀(20)을 성형시키는 스크류코어(6)가 설치되며, 상기 스크류코어(6)에는 스프라켓(821)이 설치되고 스프라켓(82)에는 모터(71)의 회전력을 스크류코어(6)에 전달하는 체인(81)이 설치되어 구성되며, 스크류코어(6)에는 이후 설명된 핀코어(91)가 관통되는 통공(62)과 나사홀(20)을 성형시키는 스크류(61)이 형성되어 구성된다. As shown in FIGS. 2 and 3, an upper mold 52 which is elevated by an elevating device 55 is installed above the lower mold 51, and a screw hole 20 is provided at the bottom of the lower mold 51. A screw core 6 is formed to form a screw, and the screw core 6 is provided with a sprocket 821, and the sprocket 82 has a chain 81 for transmitting the rotational force of the motor 71 to the screw core 6. Is installed and configured, the screw core 6 is formed by forming a screw 61 for forming the through hole 62 and the screw hole 20 through which the pin core 91 described later is formed.

그리고 하금형(51)의 좌우 양측에는 가스배출로(21)를 성형시키는 핀코어(91)가 설치되며, 핀코어는 실린더장치(90)에 의해 전 후진 동작되도록 구성된다.And the left and right sides of the lower die 51 is provided with a pin core 91 for forming the gas discharge passage 21, the pin core is configured to be moved forward and backward by the cylinder device (90).

이와 같이 구성되는 종래의 메인커버성형용 금형은 하금형(51)과 상금형(52)이 닫히면 하금형(51)의 양측에 설치된 실린더장치(90)가 동작되어 핀코어(91)가 전진동작되면서 스크류코어(6)에 형성된 통공(62)내를 관통 설치된다.In the conventional main cover molding die configured as described above, when the lower mold 51 and the upper mold 52 are closed, the cylinder device 90 installed on both sides of the lower mold 51 is operated so that the pin core 91 is moved forward. While penetrating through the through hole 62 formed in the screw core (6).

이와 같은 상태에서 금형의 내부로 사출물이 주입되어 메인커버(2)의 성형이 진행되며, 성형이 완료되면 상금형(52)이 승강장치(55)에 의해 상승되어 금형이 열리게 된다.In this state, the injection is injected into the mold to form the main cover 2, and when the molding is completed, the upper mold 52 is lifted by the lifting device 55 to open the mold.

이어 실린더장치(90)가 동작되어 핀코어(91)가 후퇴된 다음 모터(71)의 회전력을 체인(81)을 통해 전달받은 스크류코어(6)가 회전됨에 따라 나사홀(20)을 성형시키는 스크류(61)가 회전되면서 성형이 완료된 메인커버(2)를 하금형(51)으로부터 들어 올려 인출시킬 수 있게 된다.Subsequently, the cylinder device 90 is operated to form the screw hole 20 as the pin core 91 is retracted and the screw core 6 which receives the rotational force of the motor 71 through the chain 81 is rotated. As the screw 61 is rotated, the main cover 2 of which molding is completed can be lifted up and taken out from the lower mold 51.

이상에서와 같이 메인커버(2)에 나사홀(20)을 형성시키기 위하여는 스크류코어(6)를 회전동작시켜야 되고, 회전되는 스크류코어(6)는 정밀하게 회전되어야 만이 통공(62)의 내부로 핀코어(91)가 정확하게 관통 삽입됨에 따라 모터(71)의 회전력을 스크류코어(6)에 전달하는 동력전달장치(8)가 매우 정확하게 작동되어야 한다.As described above, in order to form the screw hole 20 in the main cover 2, the screw core 6 must be rotated, and the rotated screw core 6 must be precisely rotated to form the inside of the through hole 62. As the furnace pin core 91 is correctly inserted through, the power train 8 which transmits the rotational force of the motor 71 to the screw core 6 must be operated very accurately.

그러나 종래의 금형장치는 그 동력전달장치(8)가 체인(81)과 스프라켓(82)으로 구성되어 스프라켓과 체인과의 사이에 유동이 발생될 수밖에 없고, 이와 같은 유동은 스크류코어(6)의 회전을 정밀하게 제어할 수 없어 핀코어(91)의 전진동작시 핀코어(91)가 스크류코어(6)에 형성된 통공(62)의 내부로 삽입되지 못하는 문제가 종종 발생하였다. However, in the conventional mold apparatus, the power transmission device 8 is composed of a chain 81 and a sprocket 82 so that a flow can be generated between the sprocket and the chain. Since the rotation cannot be precisely controlled, the pin core 91 is often not inserted into the through hole 62 formed in the screw core 6 during the forward operation of the pin core 91.

이와 같은 금형장치의 작동부전은 금형을 파손시키는 문제점과 아울러 생산성을 크게 저하시키는 문제점이 있는 것이다.The malfunction of the mold apparatus as described above is problematic in that the mold is damaged and the productivity is greatly reduced.
