Claims (1)

[Claims for Utility Model Registration] The frame is composed of a main frame, first and second auxiliary frames on the left and right sides, and a third auxiliary frame on the upper side, which extend from the main frame. A fixed mold device is provided with a half-cut fixed mold on one side of a raw material supply pipe and a T-shaped tube, and a cylinder is installed along a guide rod extending over a main body frame arranged in a direction facing the fixed mold device. A first movable mold device equipped with a half-cut T-tube movable mold and a stop means is provided, and a first movable mold device is provided with a first movable mold device having a stop means. movement of an inner tube portion with an expanded portion of a T-shaped tube that moves in the left-right direction via a cylinder along a guide rod that is disposed in a direction perpendicular to the main frame and the first auxiliary frame; a second with a mold and stop means;
A movable mold device is provided, and a cylinder is disposed on the second auxiliary frame in a direction facing the second movable mold device and extends along a guide rod extending between the main body frame and the second auxiliary frame. a third movable mold device equipped with a movable mold for the inner tube portion of the T-shaped tube that moves in the left-right direction via the movable mold and a stop means;
Further, a third auxiliary frame is provided with a cylinder located along a guide rod which is located on the line of union of the fixed mold device and the first movable mold device and is passed between the main body frame and the third auxiliary frame. A fourth movable mold device including a movable mold for a branch pipe portion of a T-shaped pipe that moves in the vertical direction and a stop means is provided, and the second and third movable mold devices are connected to the fixed mold device. When the four movable mold devices move to the combined position, the fourth movable mold device moves to the combined position and combines, and then the first movable mold device moves to the combined position of the four to combine, A device for molding a fugitive T-tube model for casting, wherein a fugitive model cavity of the T-tube is formed in the mold when the devices are in the combined position. When the second and third movable mold devices move to the combined position with the fixed mold device, a core is inserted, and then the fourth movable mold device moves to this combined position and is combined, and then these four An apparatus for molding a fugitive T-tube model for casting according to claim 1, wherein the first movable mold device is set so as to move to a joining position of the operator and join together.
