PROBLEM TO BE SOLVED: To enhance the accuracy in measurement of front adhesion at the time of release of an injection molded product M from a mold D by eliminating a factor causing variation. SOLUTION: A molding die member 6 in which a movable die is divided to a die body member 60 and a stay piece 61 is prepared, and this member is set in an injection molding machine in combination with a fixed die 7 and a slide die 8. After formation, the die body member 60 is removed while pressing the stay piece 61 to the fixed die 7 by the slide die 8 and holding the molded product M between them. The molded product M is pushed by an ejector pin 73, the force necessary for removing it together with the stay piece 61 from the fixed die 7 is detected by a load cell 3, and the front adhesion is determined based thereon.
