An automatic grasping and pre-twisting machine for mold adjusting thread nuts

Abstract

The invention provides an automatic grasping and pre-twisting machine for mold adjusting nuts, belonging to the technical field of injection molding machine assembly, comprising: a jaw housing; a locking cylinder connected to the jaw housing; a driving block connected to the locking jaw The cylinders are connected and can slide up and down relative to the jaw housing; the crank jaws are two in number and arranged on both sides of the drive block, the middle part of each crank jaw is hinged with the jaw housing, and the upper end of the crank jaw is connected to the drive block. The block is connected, and the lower end of the crank jaw is equipped with a guide wheel; the pre-tightening mechanism includes a pre-tightening motor connected to the drive block, and a pre-tightening wheel is installed at the output end of the pre-tightening motor, and the pre-tightening wheel is located between the two crank jaws; When the driving block slides down, it drives the two crank jaws to close relatively, and the two guide wheels cooperate with the pre-tightening wheel to clamp the mold adjusting screw nut, and when the pre-tensioning wheel touches the mold adjusting screw nut, it can drive the mold adjusting screw nut to rotate . The invention has the advantages of simple structure and flexible use.

Description

technical field [0001] The invention belongs to the technical field of injection molding machine assembly, and relates to an automatic grasping and pre-twisting machine for mold adjustment screw nuts. Background technique [0002] During the assembly process of the mold clamping parts of the injection molding machine, after the tie rod is worn, the mold adjustment nut needs to be pre-screwed onto the tie rod. At present, in most cases, the workers manually lift the adjusting screw nut, and then manually screw it on the tie rod. [0003] Manual assembly is labor-intensive and inefficient. For this reason, the applicant previously provided a large-scale injection molding machine mold adjusting screw nut automatic spinner device, the application number is 201911423416.3, which includes a positioning platform, mold adjuster screw nut automatic spinner device and control device, the automatic screw mounting device for mold adjusting screw nuts includes a second base, a third sli...

[0003] Manual assembly is labor-intensive and inefficient. For this reason, the applicant previously provided a large-scale injection molding machine mold adjusting screw nut automatic spinner device, the application number is 201911423416.3, which includes a positioning platform, mold adjuster screw nut automatic spinner device and control The device, the automatic screw mounting device for the mold adjusting screw nut includes a second base, the second base is provided with a third sliding seat for longitudinal sliding, the third sliding seat is provided with a fourth sliding seat for second horizontal sliding, and the fourth sliding seat The fifth sliding seat is provided with the second vertical sliding, the fifth sliding seat is provided with the sixth sliding seat for longitudinal sliding, the fifth sliding seat is provided with the first cylinder, and the sixth sliding seat is provided with a pair of parallel The rotating roller, the sixth sliding seat is provided with a seventh sliding seat that slides horizontally, the seventh sliding seat is provided with a hydraulic motor, and the output shaft of the hydraulic motor is provided with a gear

[0004] However, this mold adjusting screw nut rotating device needs to be equipped with a specific positioning structure to position and carry the mold adjusting screw nut, resulting in a complex structure of the whole device, and the installation environment of the mold adjusting screw nut is relatively fixed, and it is inconvenient to use
