Title: Mold temperature control method and apparatus therefor
Inventor: OGAWA SATOSHI
IPC: B29C45/78
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To markedly reduce the irregularity of a molded product by stopping the operation of a mold when abnormality is generated in a series of sequence controls of the mold and changing over sequence controls so that the control objective value of the mold becomes a value at a time of standby to control the medium temp. of the mold. SOLUTION: An average value calculation part 66 calculates the average value of the control objective value set by a temp. setting part 64 and the bottom value calculated by a PID operation part 65 during a period when a molding cycle is executed. When a temp. control sequencer 11 judges that operation is interrupted because abnormality is generated, the operation of the PID operation part 65 of a mold temp. control part 61 is stopped and the contact of a changeover device 13 is changed over to an a-side and the average value calculation part 66 is connected to the PID operation part 33.  Since the average value calculation part 66 calculates the average value of the medium temp. objective value of the PID operation part 65 and a mold temp. set value, the PID operation part 33 of a medium temp. control part 31 sets the calculated average value to the control objective value to control medium temp.
