Mold adjustment device of injection molding machine provided with spherical bearings
View Patent ↗A mold adjustment device of an injection molding machine is required for movement of a rear template that moves depending on a size of a mold in a toggle clamp of the injection molding machine. At this time, a spherical bearing and/or a bushing is attached to an outer circumference of a nut of a tie bar gear that rotates along a tie bar and a tie bar screw enduring a clamping force of the toggle clamp so as to be contacted with the rear template. This mold adjustment device clears up any factor generating vibration or noise during the injection molding, thereby remarkably decreasing stoppage generated during the mold adjustment process and also relatively reducing vibration and noise.
1. A mold adjustment device of an injection molding machine, which is required for movement of a rear template that moves depending on a size of a mold in a toggle clamp of the injection molding machine,
wherein a spherical bearing and/or a bushing is attached to an outer circumference of a nut of a tie bar gear that rotates along a tie bar and a tie bar screw enduring a clamping force of the toggle clamp so as to be contacted with the rear template, and
wherein a groove is formed in a length direction in an outer side of the nut.
2. A mold adjustment device of an injection molding machine, which is required for movement of a rear template that moves depending on a size of a mold in a toggle clamp of the injection molding machine,
wherein a spherical bearing and/or a bushing is attached to an outer circumference of a nut of a tie bar gear that rotates along a tie bar and a tie bar screw enduring a clamping force of the toggle clamp so as to be contacted with the rear template,
wherein the spherical bearing including the nut is integrally formed into one member including a nut unit and a spherical bearing unit, and
wherein a groove is formed in a length direction in an outer side of the nut unit.
