<P>PROBLEM TO BE SOLVED: To provide an automatic greasing method that can prevent a wasteful operation of a grease pressure-feeding pump when greasing with quantitative valves utilized at to-be-greased locations of an electric injection molding machine. <P>SOLUTION: When the to-be-greased locations of the electric injection molding machine are fed with grease utilizing quantitative valves (50) which are so arranged that, while the grease pressure-feeding pump (41) is at work for a set period, the pressure of grease ejected out brings a prescribed amount of grease accumulated last time to be greased to to-be-greased locations (U), whereas if the pressure of the grease disappears upon the grease pressure-feeding pump coming to a standstill, a prescribed amount of grease to be ejected next time is arranged to be accumulated, wherein the set period is made shorter during summer and longer during winter in response to the ambient temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT |
