The utility model belongs to the technical field of hollow molding equipment, in particular to an auxiliary mold mechanism for connecting with the main mold of a blow molding machine. It comprises an auxiliary mold provided with a mold cavity for wrapping the product. Cooling water channels are arranged all around the mold cavity. After the product is cooled in the main mold of the blow molding machine for a certain period, the main mold opens, and the auxiliary mold wraps the preliminarily cooled product in its cavity. A pin is inserted into the air supply port to feed compressed air, making the product expand to fit the cavity for cooling and further shaping. At the same time, heat from the product is transferred through the front and rear molds and the bottom, and carried away by the flowing liquid in the cooling water channels. The above auxiliary mold mechanism shares the cooling task of the main mold of the blow molding machine, shortens the cooling time of the main mold, speeds up the production cycle of the blow molding machine, and improves production efficiency and output.
