NADCA Video News Update - Mechanical Maintenance & Evaluation of Die Cast Machines: DCM Primary Mechanical Structures - Highlight
The material presented in this video are some highlights from NADCA’s online webinar - Mechanical Maintenance & Evaluation of Die Cast Machines: Die Casting Machine Primary Mechanical Structures - presented by Jerald Brevick. The first in the Mechanical Maintenance & Evaluation of Die Cast Machines series covers topics related to the major mechanical support structures of die casting machines; the machine base, rails, platen supports, wear pads, die carriers, tie bars and bushings.

Transcription of the highlight sample:
"Jerald Brevick: There's more detail here, folks. If we just take a look at the back plate for a moment, it's usually sitting on top of what's called a plate support. In this case, it's the back plate support. The back plate support rides on top of a wear plate, or support plate some people call it, and this hole here is where lubricant is pumped in. There are channels, which we'll see in a moment, that distribute the lubricant between the wear plate and the rails.
This wear plate is supposed to be a, relatively speaking, sacrificial part of the system. The rails are supposed to not wear out, and if anything wears it should be this plate that can be, relatively speaking, more easily replaced than the rails mounted on the base of the machine. Anyway, the back plate moves back and forth in this manner from left to right. It's key to the back plate support so it doesn't move with respect to that support.
Then you have wipers, which are usually some kind of copper alloy which is relatively soft, that "wipes" the lubricant and distributes it as well as wiping away any debris, like dirt in the environment of the die casting machine, like flash from die castings that floats down and ends up sticking on the rails, or dirt or grime or other debris in the work environment. It wipes that away so it doesn't get in between the rail and the wear plate and cause galling and scratching.
These wipers are replaceable, and therefore to keep the wiper in place, we have these keepers, which are simply held in place with machine screws. You take the keepers off and you remove the wiper, put a new wiper on, and put it back in place. That's a regular thing you should inspect and make sure the wipers are doing their job and not getting worn out.
Again, basically you want to keep this well lubricated between the rails and the wear plate. If you get a system failure with your lube, or use the wrong lube, of you get contaminants or fine pieces of debris in here, you're going to wear your rails out and you're going to wear your wear plate out pretty quickly.

GRIFLUBE® Slide-Way 68 and 220 Slide and Way Lubricating Oil
To lubricate slides and ways in all types of metalworking and machine tool applications, GRIFLUBE® Slide-Way 68 and Slide-Way 220 help maintain smooth, uninterrupted motion, provide maximum latitude in extreme pressure protection while preventing stick-slip chatter in the machine tool feed. They are unusually resistant to removal by the detergency of synthetic coolants and soluble oils thus minimizing the degree of tramp oil contamination limiting biological attack of the coolant. To learn more about Slide-Way 68 and 220’s superior lubrication and protection properties, request bulletins and technical papers.
