Description

Technical Field

[0001] The utility model belongs to the technical field of casting mold auxiliary equipment, and in particular relates to a low-pressure casting mold ejector lubricating device. Background Art

[0002] At present, the common method for lubricating the center push rod of the mold during the casting process in the market is to remove the upper mold push rod reset cover after the mold is taken off the machine, take out the center push rod and apply lubricating oil. The single lubrication work is cumbersome. During the high-temperature continuous operation of the casting mold, the lubrication effect will decay over time, resulting in rapid wear of the center push rod, deformation of the center push rod after the resistance increases, and the inability to completely reset the center push rod.

[0003] Chinese patent application No. 202121049428.7 discloses a central push rod lubricating device for an aluminum alloy cast wheel hub casting mold, including a refueling pipeline, a multi-layer oil pipe group connected to the refueling pipeline, a mold core pressing plate connected to the bottom of the multi-layer oil pipe group, a plurality of oil storage tanks on the top surface of the mold core pressing plate, and a push rod hole inside the oil storage tank; wherein the multi-layer oil pipe group includes an upper oil pipe structure, a middle oil pipe structure, a lower oil pipe structure, an upper oil guide pipe group, a middle oil guide pipe group and a lower oil guide pipe group, and the upper oil guide pipe group, the middle oil guide pipe group and the lower oil guide pipe group are all composed of a plurality of uniformly distributed conduits, the number of conduits of the upper oil guide pipe group is less than the number of conduits of the middle oil guide pipe group, and the number of conduits of the middle oil guide pipe group is less than the number of conduits of the lower oil guide pipe group; the plurality of conduits in the lower oil guide pipe group are respectively connected to a plurality of oil storage tanks. The utility model has the advantages of convenient refueling operation, uniform supply of lubricating oil and reliable lubrication.

If the lubricating oil itself condenses during oil injection, its lubrication effect will also be affected. At the same time, although the lubrication structure provided therein enables the lubricating oil to be injected evenly through the setting of multi-layer pipelines, the setting of the pipelines being too long will also cause waste of the lubricating oil.
