The bottom of the support platform 4 slides inside the second track groove 601 through rollers, and a second hydraulic rod 602 for driving the support platform 4 to move back and forth along the inside of the second track groove 601 is arranged inside the base body 6; a base moving along the length direction of the conveying platform 2 is arranged at the bottom of the sand adding mechanism.

[0024] A transport mechanism that moves along the length direction of the transport platform 2 is provided on the top of the transport platform 2, and the upper end of the transport mechanism is connected to a template box that moves to the bottom of the sand discharge pipe 101. A baffle device that elastically squeezes the template box is provided on the top of the transport platform 2, and leaves the bottom of the sand discharge pipe 101 through the template box, and the baffle device automatically seals the bottom outlet of the sand discharge pipe 101; the transport mechanism is located on a mold box 204 on the outside of the transport platform 2, and a track cavity 201 that runs through the top of the transport platform 2 is provided inside the transport platform 2.
