(1) Units comprising in-mold assembly LCA

The in-mold assembly LCAs are comprised of the following units.

a)Linear motion unit (Up/Down direction)
b)Linear motion unit (Fore/Aft direction)←
c)Crimping/Swaging/Press unit
d)Positioning unit
e)Linear actuator
f)Posts

(2) Linear motion unit (Fore/Aft) construction example

The fore/aft linear motion unit can be constructed as an application variation of up/down linear motion units. But since the fore/aft units typically are required to move the base plate surfaces, slide guides are more often used rather than linear bushings.

(1) A simplified press unit with slide guides/slide blocks

The following procedures are the notable points on the guide rail and slide block assembly and adjustments.

-Locate one of the two guide rails as a datum guide rail (A).
-Adjust the air cylinder parallel to the datum guide rail and fix.
-Temporarily assemble the other guide rail (B) and the slide block (Loosely tighten the guide rails screws)
-Lightly press the guide rail (B) against the slide block, and tighten the screws of the guide rail (B) while observing that the slide block moves smoothly without any play.

(2) Manual linear motion unit
