Abstract
A safety apparatus includes a safety bar that is capable of moving in a mold clamping direction and a mold opening direction, in conjunction with a moving platen provided with a movable mold, and a latch that contacts the safety bar when a door, which is provided in a cover of an injection molding device, is open, wherein the latch includes a notch in a surface thereof on the mold-opening-direction side.
Claims18
A safety apparatus, comprising:
- a safety bar that is movable in a mold clamping direction and a mold opening direction, in conjunction with a moving platen provided with a movable mold;
- and
- a latch configured to contact the safety bar when a door is open, the door being provided in a cover of an injection molding device,
- wherein the safety bar includes a plurality of grooves provided at intervals along a longitudinal direction of the safety bar, and an inclined portion that is provided between the plurality of grooves and has a distance from an axis of the safety bar that becomes greater farther in the mold clamping direction,
- wherein the latch includes a notch in a surface thereof on a side in the mold opening direction, and
- wherein the notch includes an indentation on a surface of the latch that is on the side in the mold opening direction, the notch extending to a bottom surface of the latch and being distanced from an other surface of the latch that is on a side in the mold clamping direction,
- wherein the latch includes a plurality of latch portions arranged along the mold clamping direction and the mold opening direction,
- wherein the notch is provided in at least one of the plurality of latch portions, and
- wherein a thickness of a latch portion of the latch portions that is exposed, to the moving platen is more than a thickness of another latch portion of the latch portions that is located adjacent to the latch portion of the latch portions.
