Claims
- 1. A method of at least partially removing, from between the opposed stationary and movable platens of a molding machine, a tie rod which extends from a supportive structural frame freely through the movable platen to connection with the opposed stationary platen, said method comprising the steps of:
- slidingly translating said movable platen toward said stationary platen freely along a plurality of independent tie rods connected to said stationary platen;
- releasing at least one of said tie rods from connection with said stationary platen;
- actuating a remote control mechanism connected to a power-actuated brake mechanism carried by said movable platen, to shift said brake mechanism into engagement with said one tie rod to connect said one tie rod to said movable platen for movement therewith;
- slidingly translating said movable platen freely along those of said tie rods remaining connected to said stationary platen, to shift said one tie rod to a position away from said stationary platen;
- actuating said remote control mechanism to shift said brake mechanism out of engagement with said one tie rod to disconnect said one tie rod from said movable platen;
- slidingly translate said movable platen toward said stationary platen freely along said tie rods;
- actuating said remote control mechanism to shift said brake mechanism into engagement with said one tie rod to connect said one tie rod to said movable platen for movement therewith; and
- slidingly translating said movable platen freely along said remaining tie rods, to shift said one tie rod yet further away from said stationary platen.
- 2. A method of at least partially removing, from between the opposed stationary and movable platens of a molding machine,
- a tie rod which extends from a supportive structural frame freely through the movable platen to connection with the opposed stationary platen, said method comprising the steps of:
- slidingly translating said movable platen freely along a plurality of said tie rods to a first location adjacent said stationary platen;
- releasing at least one of said tie rods from connection with said stationary platen by shifting a pair of arms, movably mounted on said stationary platen, from engagement with said one tie rod;
- actuating a remote control mechanism connected to a power-actuated brake mechanism carried by said movable platen, to shaft said brake mechanism into frictional engagement with said one tie rod to frictionally connect said one tie rod to said movable platen for movement therewith;
- slidingly translating said movable platen freely along those of said tie rods remaining connected to said stationary platen to a first position away from said stationary platen;
- actuating said remote control mechanism to shift said brake mechanism out of frictional engagement with said one tie rod to disconnect said one tie rod from frictional clamping connection with said movable platen and slidingly translating said movable platen relative to said one tie rod toward said stationary platen to a second location short of that required to displace said movable platen beyond the released end of said one tie rod and short of said first location; and again actuating said remote control mechanism to shift said brake mechanism into frictional engagement with said one tie rod to frictionally clamp said one tie rod to said movable platen for movement therewith and translating said movable platen away from said stationary platen to shift said one tie rod yet further away from said stationary platen.
- 3. A method according to claim 2 wherein said last named releasing step further comprises removing a bolt from aligned apertures in said arms prior to shifting of said arms.
- 4. A method according to claim 2 wherein said last named releasing step further comprises displacing a pair of links from acting upon the interconnected ends of a pair of links, whose other ends ae connected to respective ones of said links, to shift said links from a relatively inclined orientation to a longitudinally aligned orientation to separate said arms away from one another and from said one tie rod.
