Abstract
A guide and retention assembly for spaced apart confronting plates of a die set for guiding the plates for relative reciprocal movement toward and away from the other. The assembly includes a housing with a mounting flange and a sleeve with a through bore, and a rod extending through the bore and slidably received in at least one bushing in the sleeve.
Claims22
A guide and retention assembly for spaced-apart plates comprising:
- a housing having a flange, a sleeve, and a bore through the flange and sleeve, the flange constructed for attachment to a first plate with the sleeve received in a hole in the first plate;
- at least one bushing received in the bore and located in the sleeve;
- and
- a rod slidably received in the bushing for axial reciprocation relative to the housing, a groove in the rod and adjacent one end of the rod, and the rod adjacent the one end is constructed for attachment to a second plate that confronts the first plate;
- a stop carried by the rod adjacent an other end of the rod, extending radially outward of the rod and engageable with the sleeve to limit axial movement of the rod in one direction relative to the housing;
- a wiper seal adjacent the flange end of the bore and bearing on the rod to prevent contaminants from entering the bore and the wiper seal can be received in the groove to releasably retain the rod in the housing and releasably limit axial movement of the rod relative to the housing in a direction opposite to the one direction;
- and
- another wiper seal carried by the sleeve and adjacent an end of the bore distal from the flange and bearing on the rod to prevent contaminants from entering the bore, and the stop is engageable with the another wiper seal to cushion further axial movement of the rod in the one direction relative to the housing.

A guide and retention assembly for spaced-apart plates comprising:
- a housing having a flange, a sleeve, and a bore through the flange and sleeve, the flange constructed for attachment to a first plate with the sleeve received in a hole in the first plate;
- at least one bushing received in the bore and located in the sleeve;
- and
- a rod slidably received in the bushing for axial reciprocation relative to the housing, the rod constructed for attachment to a second plate that confronts the first plate;
- and a groove in the rod and the groove is located near the construction for attachment of the rod to the second plate;
- a wiper seal located near an end of the bore and bearing on the rod to prevent contaminants from entering the bore, and the wiper seal can also be received in the groove to releasably retain the rod in the housing;
- and
- wherein the wiper seal and associated end of the bore are located at the flange of the housing.
5 more elements
A guide and retention assembly for spaced-apart first and second plates comprising:
- a housing having a through bore with first and second ends and constructed for attachment adjacent the first end of the bore to a first plate;
- at least one bushing received in the bore and carried by the housing;
- a rod with first and second ends, constructed for attachment adjacent a first end of the rod to a second plate, slidably received in the bushing and extending through the bore and the housing for axial reciprocation of the rod relative to the housing;
- a first wiper seal carried by the housing near the first end of the bore and circumferentially continuously bearing on the rod to prevent contaminants from entering the bore;
- a second wiper seal carried by the housing near the second end of the bore and circumferentially continuously bearing on the rod to prevent contaminants from entering the bore;
- the bushing being received between the first and second seals;
- a stop carried by the rod near the second end of the rod and extending radially outwardly of the rod for engagement with the housing near the second end of the bore to limit axial movement of the rod in a first axial direction relative to the housing;
- and
- a groove in the rod near the first end of the rod and releasably engageable with the first wiper seal near the first end of the bore to releasably limit the extent of axial movement of the rod relative to the housing in a second axial direction opposite to the first axial direction.
