Injection-molding machine with transverse feed

Claim 1

An injection-molding machine comprising a mold composed of a plurality of mold plates relatively movable between an open-mold and a closed-mold position along an axis perpendicular to their major surfaces, at least one of said mold plates being provided with inlet means leading from an edge thereof to a cavity formed therein, drive means for relatively moving said mold plates along said axis, resiliently mounted injection means offset from said axis including nozzle means alignable with said inlet means in said closed-mold position, said nozzle means being displaceable in a direction generally transverse to said axis, positioning means synchronized with said drive means for aligning said nozzle means with said inlet means in said closed-mold position preparatorily to introduction of a flow of hardenable plastic mass through said inlet means into each cavity, and bracing means on said mold normally disengaged from said injection means but engageable therewith upon such alignment for displacing said nozzle means in said generally transverse direction for operative coupling with said inlet means, such displacement being facilitated by the resilant mounting of said injection means.
