Abstract: A tool closing system for plastic blow molding machines comprises a drive base plate, a front mold clamping plate and a rear mold clamping plate positioned between the front clamping plate and the base plate. The base plate, front clamping plate, and rear clamping plate are shiftably arranged on guides which are mounted on a carriage. A drive device is fastened to the base plate and comprises an extensible and retractable drive rod which is articulated to the rear clamping plate for force transmission without bending moment. Two substantially C-shaped or U-shaped frame elements are arranged side by side in parallel with the guides. Each have a substantially horizontally extending central web and two substantially vertically extending webs. A respective one of the two vertical webs is articulated to the base plate and the other vertical web is articulated to the front clamping plate.
