The utility model discloses one-step method is annotated and is drawn blow hollow molding machine drawing mechanism mode locking device's technical scheme is: the mechanical rotary table comprises a stretching base arranged on a machine rotary table seat, wherein a stretching seat guide rod and an air cylinder mounting plate are arranged on the stretching base, a stretching seat air cylinder is arranged on the air cylinder mounting plate, a stretching seat is arranged on the stretching seat guide rod in a sliding mode, the stretching seat air cylinder is connected with the stretching seat, the stretching seat is provided with a stretching air cylinder and a stretching guide rod, the stretching air cylinder and the stretching guide rod are connected with the stretching mounting plate, and a stretching assembly is arranged below the stretching mounting plate.
The utility model discloses a hollow forming machine drawing mechanism mode locking device is blown in injection of one-step method, in operation, the machine is behind the compound die of moulding plastics, tensile seat of tensile seat cylinder drive and tensile subassembly descend, after the decline targets in place, the lockpin cylinder begins to move, it passes in the lockpin that the via hole stretched into tensile seat to drive the lockpin, accomplish the mode locking, tensile subassembly begins tensile action and blows this moment, blow and accomplish the back, at first tensile mounting panel of tensile cylinder drive is returned to the primary point position, then the lockpin cylinder drives the lockpin and returns to the primary point position, after the tensile seat of redraw cylinder drive returns the primary point, the machine begins blow mould and die sinking and gets into next circulation. The stretching seat cylinder and the lock pin cylinder can adopt a small-diameter cylinder, energy consumption is saved, the mold is locked through the transverse lock pins on two sides, the mold locking is more reliable, the mold does not expand, and the product quality is better.
The utility model discloses a hollow forming machine drawing mechanism mode locking device is blown to one-step method notes, via hole and lockhole in all set up the guide pin bushing, the guide pin bushing is stand wear and tear, it is convenient to change. The two side walls of the stretching base are respectively provided with a lock pin cylinder base, the lock pin cylinder is installed on the lock pin cylinder base, and the lock pin cylinder base is arranged, so that the lock pin cylinder is convenient and firm to install.
