Abstract
Abstract An injection mold/injection blow mold having a rotary manifold fed axially from either one, or optionally, two, axially movable injectors located at the respective ends of the manifold, through rotary, axial-slip joints, and having one or more clamps which reciprocate at an angle to the axis of the manifold to co-act in forming molded products of material dispensed through the manifold; sets of mold cavities in the manifold and corresponding sets of cores on each clamp are provided, and both one-directionrotating and oscillating manifold motion are disclosed, the whole making possible simultaneous two-color and combined-color molding in low-radius, high speed manifold operation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
99 words
A molding system comprising: manifold means, bearing means for rotatively supporting the manifold means, said manifold means having a distribution system therein including a sprue located along the rotative axis of the manifold means, said sprue being connective with cavity means in a surface of the manifold means radially disposed with respect to the rotative axis of the manifold means, means for introducing material into the axial sprue and means for reciprocating into and away from said cavity means at an angle to the axis of the manifold means for thereby receiving and removing material from said cavity means.
Claim 2
Dependent Claim
99 words
A molding system comprising: manifold means, bearing means for rotatively supporting the manifold means, said manifold means having a distribution system therein including a sprue located along the rotative axis of the manifold means, said sprue being connective with cavity means in a surface of the manifold means radially disposed with respect to the rotative axis of the manifold means, means for introducing material into the axial sprue and means for reciprocating into and away from said cavity means at an angle to the axis of the manifold means for thereby receiving and removing material from said cavity means.
Claim 3
Dependent Claim
96 words
A molding system comprising: manifold means, bearing means for rotatively supporting the manifold means, said manifold means having a distribution system therein including an axial sprue connective with cavity means in an outer surface of the manifold means, said cavity means including Plural, oppositely directed cavities; means for introducing material into the axial sprue comprising an injector at each end thereof, and means for reciprocating into and away from said cavity means at an angle to the axis of the manifold, including plural, oppositely directed cores, for thereby receiving and removing material from said cavity means.
Claim 4
Dependent Claim
96 words
A molding system comprising: manifold means, bearing means for rotatively supporting the manifold means, said manifold means having a distribution system therein including an axial sprue connective with cavity means in an outer surface of the manifold means, said cavity means including Plural, oppositely directed cavities; means for introducing material into the axial sprue comprising an injector at each end thereof, and means for reciprocating into and away from said cavity means at an angle to the axis of the manifold, including plural, oppositely directed cores, for thereby receiving and removing material from said cavity means.
Claim 5
Dependent Claim
37 words
A molding system as recited in claim 2, wherein a portion of at least one injector has an axially movable connection with the manifold means for thereby reducing pressure in the manifold means by said axial movement.
Claim 6
Dependent Claim
23 words
A molding system as recited in claim 3, wherein portions of both injectors are axially movable for reducing pressure in the manifold means.
Claim 7
Dependent Claim
19 words
A molding system as recited in claim 3, wherein said axially movable connection includes an axially overlapping rotative-translative connection.
Claim 8
Dependent Claim
22 words
A molding system as recited in claim 5, wherein the bearing means includes a journal at each end of the manifold means.
Claim 9
Dependent Claim
36 words
A molding system as recited in claim 2, wherein the distribution system includes a valve adapted, when closed, to restrict respective portions of said sprue and cavity means to introduction of material by the respective injectors.
Claim 10
Dependent Claim
36 words
A molding system as recited in claim 7, wherein additionally, plural, oppositely directed blow molds aligned for co-action with said cores are provided at a rotative angle about said axis with respect to said cavity means.
Claim 11
Dependent Claim
39 words
A molding system as recited in claim 8, wherein the cavity means includes additionally, a further plurality of oppositely directed cavities disposed at a rotative angle about said axis with respect to the first said cavities and blow molds.
Claim 12
Dependent Claim
71 words
A molding system as recited in claim 9, wherein the means for reciprocation includes clamp means, platen means, and tie bar means; with the platen means mounting said cores, with the tie bar means transverse to said manifold means axis of rotation, and with the clamp means adapted to reciprocate the platen means along the tie bar means with the oppositely directed cores diametrically aligned with respect to said manifold axis.
