Title: Automatic setting method for mold clamping force of toggle type mold clamping device
Inventor: SHIMIZU MIYUKI
IPC: B29C33/22
Filed: 1990-07-31
Abstract: PURPOSE:To make it possible to automatically set mold clamping force accurately only by giving values by a method wherein the set position of a pad platen is calculated on the basis of the set values of mold thicknesses and of mold clamping force and set so as to stop the moving pad platen when the platen reaches the set position and to detect its stop position in order to compare the detected value with the set position of the pad platen. CONSTITUTION:A central controller 14 calculates the set position, at which the set mold clamping force is to be developed, of a pad platen l on the basis of the set values of mold thicknesses and of mold clamping force and set the calculated set position and, after that, issues command to a motor 17 for controlling the position of the pad platen l. In accordance with the command, the motor 17 pivots so as to drive a chain 19 in order to pivot a sprocket 16 together with 15 by the predetermined amount, resulting in moving the pad platen 1 to the set position. When the pad platen 1 reaches said set position, the motor 17 is stopped and the position of the pad platen 1 is detected. After that, the detected position of the pad platen 1 is compared with the set position of the pad platen l so as to judge whether the comparison result lies within the allowable value or not. When the result lies within the allowable value, the setting process of mold clamping force is brought to and end. When the result does not lie within the allowable value, the position of a crosshead 6, at which the set mold clamping force is to be developed, is calculated. After that, by setting said calculated value as a mold clamping position, the setting process of mold clamping force is brought to an end.
