<P>PROBLEM TO BE SOLVED: To provide a mold clamping force setting method and a molding clamping force setting device for an injection molding machine in which a proper clamping force according to the resin pressure produced by the injection of a resin to a mold can be set without producing burr and deforming the mold. <P>SOLUTION: The maximum value (Amax) of the mold clamping force detected when a first set mold clamping force (A) is set and injection is carried out and the maximum value (Bmax) of the mold clamping force detected when a second set mold clamping force (B) is set and the injection is carried out are a combination of two groups in which the maximum values of the mold clamping forces in the injection are made larger than the set mold clamping force. By the combination of two groups, two coefficients a, b of a linear approximation formula (Fmax=a*Fs+b) are found, an intersection point of Fmax=Fs to the linear approximate equation (Fmax=a*Fs+b) is found and a proper set mold clamping force Fs<SB POS="POST">(good)</SB>is obtained so that the maximum value of the detected mold clamping force and the set mold clamping force are made equal to each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
