Embodiment Construction

[0025] exist figure 1 The middle part schematically shows a part of an injection molding machine 1 comprising rods 9 and pins 10 and a lubricant circulation circuit. A lubricant 4 (fluid grease, lubricating oil) is located in the container 2 , which lubricant is pumped into the supply line 5 by a lubricant pump 8 . Lubricant 4 is supplied via metering elements 14 to lubrication points 11 of respective lever joints 7 . The circulation circuit can here be implemented in such a way that the lubricant 4 flows back after flowing through the single lubrication point 11 . However, in a preferred embodiment, all lubricating points 11 that are preferably highly loaded are flowed in parallel and the lubricant 4 is then returned pressure-free through the discharge line 3 . For this purpose, no continuous pressure is required in the entire lubricant circuit. The pressure that builds up in the lubricant pump 8 and is required for the lubricant delivery is mainly reduced in the region of...

Abstract

A lubricating device for an injection molding machine (1) with at least one collecting container (2) for lubricant (4), a feed line for lubricant (4) to a lubricating point (11) and a drain line for a lubricant (4) from a lubricating point (11), the Lubricating device comprises at least two lubrication points (11) supplied and to each of the at least two lubrication points (11) has a separate feed line (5), so that the lubrication points (11) parallel with lubricant (4) are supplied and wherein from each lubricating point (11) a drain line (3) leads away, in which the lubricant (4) in flow direction from the lubrication point (11) expires, said itself biased in each discharge line (3) exploiting dividend lubricant (4) in the region of each lubricating point (11) against the flow direction.

Description

technical field [0001] The invention relates to a lubrication device for injection molding / die casting machines. Background technique [0002] A lubricating device of the same type is known from DE 10 2008 024 514 B4. The advantage of this lubrication system is that no oil film or mist is created in the area of ​​the injection molding machine. Energy is saved and wear on the seals of the lubricant circulation system is greatly reduced by avoiding continuous oil flow. By supplying the individual lubrication points in parallel, a uniform distribution of the lubricant at the individual lubrication points is achieved without having to ensure a continuously high pressure, as is the case, for example, in pressure-circulating lubrication. [0003] In DE 10 2008 024 514 B4 the lubricant, after lubricating the individual lubrication points, flows into a container which is viewed in a vertical plane (DE 10 2008 024 514 B4 figure 1 section) is arranged vertically below all lubricati...
