A lubricant such as grease is supplied by a grease supply device to a grease supply point of an injection molding machine. A workload of a movable portion forming the injection molding machine when the movable portion operates is calculated and a grease supply command is output to the grease supply device when the calculated workload exceeds a reference value. An operating state of the injection molding machine is evaluated by using the workload reflecting a load on the movable portion and, in this way, insufficiency of lubrication of the movable portion is anticipated.

Automatic grease supply device of injection molding machine

An initial weight of a grease storing cartridge attached to a pump is measured, and the measured value is compared with a reference weight and it is determined whether the initial weight of the cartridge is within an appropriate range or not. The weight of the cartridge is measured before and after execution of one operation cycle of the pump, and it is determined whether the difference therebetween (i.e., weight of grease which is actually supplied during one operation cycle) is within an appropriate range or not.

Grease supply apparatus

An injection molding machine capable of easily moving a body of the injection molding machine and its associated peripheral equipments, and eliminating daily correction of the position of the peripheral equipments. A rest (,) having a peripheral-equipment mounting plate (,) is fixed to the body (,) of the injection molding machine, and a robot (,) and a peripheral equipment (,) cooperating with the injection molding machine body (,) are mounted on the plate (,). In moving the injection molding machine body (,) to another location, the robot (,) and the peripheral equipment (,) can be transported together with the injection molding machine body (,). Thus, detachment of the peripheral equipments from the injection molding machine and re-connection of cables and piping become unnecessary, and also the relative positioning does not displaced.
