When the conveying frame body 1 of this structure pushes the sand core tray to transport the sand core through a plurality of rollers 2, the insertion rod 4 can be inserted into the inside of the fixed sleeve 3 to install the guide frame 7 on both sides of the top of the conveying frame body 1, and the push rod 5 can push the guide frame 7 to the appropriate position on both sides of the sand core tray by lateral pushing at the top of the insertion rod 4, and the guide frame 7 can also be rotated to the appropriate front and rear inclination angle and positioned on the outer side of the fixed plate 6, so that the guide frame 7 can correct and guide the sand core tray transported on the roller 2 through a plurality of cylindrical rollers 8, so as to avoid the problem that the sand core tray is easily offset when being transported on the roller 2, resulting in the sand core moving in the tray and causing bumps and defects. , thereby ensuring the production quality of the sand core, a fixed shaft 9 is provided on one side of the fixed plate 6 adjacent to the guide frame 7, and a rotating sleeve 10 movably sleeved on the outside of the fixed shaft 9 is provided on the back side of the guide frame 7. The guide frame 7 of this structure can be rotated outside the fixed shaft 9 by the rotating sleeve 10 to adjust to different front and rear inclination angles, so that the cylindrical roller 8 can correct and guide the sand core pallet transported on the roller table 2 at a suitable position, and recesses 11 are provided at the upper and lower ends of the back side of the fixed plate 6, and a fixing pin 12 is inserted on the bottom wall of the recess 11, and the outer end of the fixing pin 12 passes through the outer side of the fixed plate 6, the outer end of the fixing pin 12 is an arc-shaped surface structure, and an insert 13 is fixed to the arc surface of the outer end of the fixing pin 12, and the upper and lower ends of the outer wall of the rotating sleeve 10 are provided with The arc-shaped embedding groove that matches the structure of the embedding block 13.
