摘要:
A nozzle touch mechanism for an injection molding machine which acts to prevent inclination of a mold (40) and a stationary platen (30) to which the mold is attached caused by a nozzle touch force, and makes easy maintenance and inspection of the injection mechanism comprises a nozzle touch mechanism for moving an injection mechanism (10) relatively to the mold (40) attached to the stationary platen (30) so that a nozzle (10a) of a heating cylinder (10b) touches and pushes a spool of the mold. The nozzle touch mechanism has a support member (20) for supporting the injection mechanism (10) to be movable, and a driving unit (65,61) arranged lower than the heating cylinder (10b) of the injection mechanism (10) for moving the injection mechanism supported by the support member, and a connection member (50) for connecting the stationary platen (30) with the driving unit (65,61). The connection member (50) and the stationary platen (30) are connected at symmetrical positions with respect to a central axis of the nozzle (10a). With the above arrangement, a nozzle touch force exerted on the mold from said nozzle (10a) is transmitted to the stationary platen (30) and balanced with a force exerted thereon from the connection member (50), so that no bending moment is produced on the stationary platen.

An automatic lubricator for an injection molding machine, capable of performing proper lubrication in accordance with operation environment of the injection molding machine. A lubrication interval Ls is controlled according to length of cycle time S of the injection molding machine so that the lubrication interval Ls is increased when the cycle time S is long and it is decreased when the cycle time S is short. Further, when a ball screw temperature t1 is high the lubrication interval Ls is accordingly decreased by ΔDL, and when the ball screw temperature t1 is low the lubrication interval Ls is accordingly increased by ΔDL. Also, when the ambient temperature t2 is high the operation time Tp of a lubricating pump 2 is decreased, and when the ambient temperature t2 is low the operation time Tp is increased to stabilize the lubrication quantity.

An industrial robot, having a manipulative robot hand for mounted on a vertically movable portion thereof moved by a vertical drive means, provided with a load reducing means which includes a pneumatic cylinder means for applying a constant upward force to the vertically movable portion during the vertical movement of the portion and air storage tank or tanks directly connected to the pneumatic cylinder means for continuously supplying air under a desired fixed pressure. The upward force contributes to reducing a load applied to the vertical drive means. The air storage tank or tanks contributes to ensuring mechanical rigidity of the industrial robot.

® A robot wrist of an industrial robot having a wrist housing supporting two orthogonally arranged rotating output shafts therein, each of the shafts being connected to a robot hand, and a built-in fluid conveying means provided for distributing pressurized air introduced from the outside of the robot wrist toward the robot hand attached to one of the rotating output shafts. An output end of each of the two rotating output shafts may either be plugged by a plug element or closed by a stop valve when the output end is not connected to the robot hand.

A ball spline nut is provided in each of tie bar penetrating holes formed in a moving platen constituting a mold clamping mechanism of an injection molding machine. On the other hand, a portion of a tie bar one end of which is fixed to a stationary platen, engaging with the tie bar penetrating hole in the moving platen, is made a ball spline shaft. Since there is no clearance between the ball spline shaft and the ball spline nut engaging therewith, in mold clamping and mold releasing processes, the posture of a movable mold attached to the moving platen with respect to a stationary mold attached to the stationary platen is always kept constant.
