The invention discloses a mold opening and closing control method of a two-plate type hydraulic injection molding machine, which comprises the following steps of: detecting and judging whether the actual position of each tiebar is within an allowable opening and closing deviation range or not between mold closing and closing, and adjusting the position of the tiebar and the mold opening distance S2 for resetting the tiebar when the conditions are not met; in this way, after the subsequent mold opening is in place, if the actual position of each tiebar is not within the deviation range of allowing opening and closing, the position of the tiebar needs to be adjusted continuously until the opening condition is met, and then the whole periodic action is completed. In this way, the mold opening distance S2 of resetting of the tie bar is automatically modified in a circulating mode, the position of the reset tie bar can be kept within the allowable opening and closing deviation range after the tie bar is automatica
