Claim 1
Independent Claim
137 words
A device for molding a plurality of parts which are to be assembled together including a first mold portion defining a cavity for a first molded part, a second mold portion defining a cavity for a second molded part directly adjacent said first part and said first and second mold portions arranged for forming an interconnecting passageway therebetween so that a bridging web of molded material is provided between said first and second molded parts in the molding operation, and means in combination with said first and second mold portions for enclosing the mold cavities around said molded parts for forming of said parts by injection molding and for relatively displacing of said molded parts to shear the bridging web therebetween and to assemble said parts and further to open said cavities to release said molded parts.
Claim 2
Independent Claim

A device for molding a plurality of parts which are to be assembled together including a first mold portion defining a cavity for a first molded part, a second mold portion defining a cavity for a second molded part directly adjacent said first part and said first and second mold portions arranged for forming an interconnecting passageway therebetween so that a bridging web of molded material is provided between said first and second molded parts in the molding operation, and means in combination with said first and second mold portions for enclosing the mold cavities around said molded parts for forming of said parts by injection molding and for relatively displacing of said molded parts to shear the bridging web therebetween and to assemble said parts and further to open said cavities to release said molded parts.
Claim 3
Dependent Claim
215 words
A mold apparatus including first wall means partly defining a first cavity for a first molded part, a first and a second plunger arranged for movement in said first wall means toward and away from each other and defining therebetween and within said wall means said first cavity for the formation of said first molded part, second wall means partly defining a second mold cavity for forming a second molded part adjacent to said first molded part but laterally oFfset in respect thereto, said second wall means in combination with said first wall means defining a passage for a connecting web between said first molded part and said second molded part, a third and a fourth plunger movable in said second wall means toward and away from each other and defining therebetween and within said second wall means said second cavity, said third and fourth plungers being movably displaceable relative to said second cavity, and said second wall means comprises a working plate containing the lateral walls of said second wall cavity and said working plate being shiftable laterally in respect to said first mold cavity for shearing the connecting web between said first and second molded parts and for positioning said second molded part in alignment with said first molded part for assembly therewith.
Claim 4
Dependent Claim
215 words
A mold apparatus including first wall means partly defining a first cavity for a first molded part, a first and a second plunger arranged for movement in said first wall means toward and away from each other and defining therebetween and within said wall means said first cavity for the formation of said first molded part, second wall means partly defining a second mold cavity for forming a second molded part adjacent to said first molded part but laterally oFfset in respect thereto, said second wall means in combination with said first wall means defining a passage for a connecting web between said first molded part and said second molded part, a third and a fourth plunger movable in said second wall means toward and away from each other and defining therebetween and within said second wall means said second cavity, said third and fourth plungers being movably displaceable relative to said second cavity, and said second wall means comprises a working plate containing the lateral walls of said second wall cavity and said working plate being shiftable laterally in respect to said first mold cavity for shearing the connecting web between said first and second molded parts and for positioning said second molded part in alignment with said first molded part for assembly therewith.
Claim 5
Dependent Claim
124 words
A device, according to claim 2, wherein said working plate defines a portion of a third molded part, means in combination with said working plate defining a third cavity and including a fifth plunger movable through said working plate and an oppositely disposed sixth plunger movable in alignment therewith, said fifth plunger being retractable from said third cavity after the third part is molded, said sixth plunger being movable for displacing said third molded part from said third cavity into said working plate, and said working plate being laterally displaceable with said second and third molded parts for movement successively into alignment with said first part in said first wall means for effecting the assembly of said first, second and third molded parts together.
