The invention discloses a stripping structure with the side-extraction core extruding modules, which changes the strip mechanism on the basis of original products. Remove the extension board of the crown bar board and the knockout board of the prior art, equip a hydraulic cylinder on the solidifying board above the module, which is through the pressure worktable board and on the top of the module; joint the piston rod and the crown bar board of the module together, therefore the crown bar does not have the linkage with the worktable board and independently sets the control of the hydraulic cylinder. The invention solves the problem that adopts the central pouring stoma to feed from the bottom and realizes the continuous manufacturing and program control. Compared with the prior art, the crown bar board of the invention will not misshape, the equipping of side-extraction core module is convenient, the structure is simple, and it is also suitable for the stripping of the non side-extraction core module.
