The utility model belongs to the technical field of hollow molding, in particular to a secondary mold of a hollow molding machine. By arranging push blocks capable of floating up and down, when the push blocks move to the lower part of the mold body, with the movement of a first support member and a second support member, the first support member and the second support member push up the corresponding push blocks, so that the push blocks move up and are respectively supported below the front mold and the rear mold, thereby enclosing to form a cavity wrapping the product. After compressed gas is injected into the product, the product is attached to the inner wall of the cavity to take away heat, realizing secondary cooling and shaping, sharing the cooling task of the main mold and shortening the cooling time of the main mold. In addition, after the above processes are completed, the first support member and the second support member are driven to reset, so that the third push block and the fourth push block move down to keep a certain distance from the mold body, and the third push block and the fourth push block are driven to move back and forth to remove the overflow. The arranged secondary mold makes the production beat of the blow molding machine faster, improves the production efficiency and has stronger practicability.
