PROBLEM TO BE SOLVED: To provide a mating method for a flask type sand mold, which is capable of preventing abrasion of molds being halfway to flask matching and pins for flask matching from deforming in a bush-bush flask mating method. SOLUTION: The method comprises the step in which a lower flask having through holes and is mounted with a lower flask upper bush and a lower flask lower bush having pin holes drilled on the upper and lower portions of the through holes is and positioned below an upper flask having through holes and is provided with mounted with an upper frame bush having pin holes drilled on the lower portion of the through holes so that the upper and lower frames face each other, the step in which flask mating pins are allowed to pierce through the pin holes of the upper flask lower bushes, the lower flask upper bushes and the lower flask blower bushes respectively, and the step in which the upper and lower flasks are mated by using the flask mating pins as a guide.
