PROBLEM TO BE SOLVED: To improve an operation property by making exchange of an insert die easy by a method wherein a support bar urged with the loaded insert die on abutting surfaces at different two positions is, in a freely slidable manner, inserted in a groove communicated to an insert die charging hole side surface open to a fixed mold side surface having a molding space opposed to a surface on which the insert die charging hole is formed. SOLUTION: For exchange of an insert die 133, after transferring a movable side template 139 downward by functioning a clamping unit 140, a support bar 134 is extracted out from in a groove 136 to outside a fixed side template main body 132 to make up-down reversal, and inserted again into the groove 13b. An inclined surface 134a of the support bar 134 abuts against an inclined surface 138 of the insert die 133. When the support bar 134 is further pushed into, the pushing force is changed to a right angled direction with the inclined surface 138 to push out the insert die 133 downward. The insert die 133 is taken out from the fixed side template main body 132, another discrimination mark engraved insert die 133 is inserted into an insert die charging hold 135, the support bar 134 is again inserted into the groove 136, and held at a specific position. The insert groove 136, and held at a specific position. The insert die can be exchanged without detaching the mold. |
