PURPOSE: To provide a continuous casting device for a grid body of a lead battery, formed with engraved grooves with an angle in an upward direction, having a superior characteristic and by which a high productive efficiency is embodied.

CONSTITUTION: Many strap shaped casting molds each of which is engraved with shapes of grid body on its plane face are annularly connected with hinge mechanisms to be couple of casting molds A and B, and A and B are arranged between couples of sprockets 5, 5' and 6, 6' to be synchronously circulated. A couple of doubling molds is formed by always pressurizing the back face of each of plural opposing strap shaped casting molds on a straight line between the sprockets. Each of the strap shaped casting molds 1 is formed with engraved grooves having an angle 10-80° in the upward direction to the horizontal face by which the adjacent molds are laterally connected.
