Abstract
Abstract A slide retainer and positioner for molds having at least one cam-actuated slide for pulling a core element laterally of the mold cavity as the mating mold parts are opened, said slide retainer and positioner being embodied wholly within the mold at all times and adapted to yieldingly clamp the slide in camaligned position only when the mold is opened without restraining the opening and closing movement of the slide.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
100 words
In a mold having at least two mating parts abutting at a parting line and forming a mold cavity and at least one camactuated slide for moving a core part laterally outward and inward of said cavity during opening and closing of the mold, the improvement comprising slide retainer and positioner means wholly enclosed within the mold and having spring-biased jaws for yieldingly gripping an element on the slide to hold it in aligned position only at the end of the cam-actuated laterally outward movement thereof and releasing said element at the beginning of the cam-actuated laterally inward movement thereof.
Claim 2
Dependent Claim
100 words
In a mold having at least two mating parts abutting at a parting line and forming a mold cavity and at least one camactuated slide for moving a core part laterally outward and inward of said cavity during opening and closing of the mold, the improvement comprising slide retainer and positioner means wholly enclosed within the mold and having spring-biased jaws for yieldingly gripping an element on the slide to hold it in aligned position only at the end of the cam-actuated laterally outward movement thereof and releasing said element at the beginning of the cam-actuated laterally inward movement thereof.
Claim 3
Dependent Claim
55 words
In a mold as described in claim 1, in which the cam-actuated movement of the slide is effected by an inclined cam pin on one mold part slidably engaging an inclined bore on the slide and the jaws grip the slide element when the pin leaves the bore during opening movement of the mold parts.
Claim 4
Dependent Claim
41 words
In a mold as described in claim 2, in which the spring-biased jaws comprise a pair of jaws pivotally connected intermediate their ends, said jaws having opposed jaw surfaces at one end and compression spring means interposed between their other ends.
Claim 5
Dependent Claim
35 words
In a mold as described in claim 3, in which the gripped element on the slide is a dowel pin and the jaws have cooperating cam surfaces for yieldingly gripping and releasing said dowel pin.
Claim 6
Dependent Claim
35 words
In a mold as described in claim 2, in which the gripped element on the slide is a dowel pin and the jaws have cooperating cam surfaces for yieldingly gripping and releasing said dowel pin.
Claim 7
Dependent Claim
41 words
In a mold as described in claim 1, in which the spring-biased jaws comprise a pair of jaws pivotally connected intermediate their ends, said jaws having opposed jaw surfaces at one end and compression spring means interposed between their other ends.
Claim 8
Dependent Claim
35 words
In a mold as described in claim 6, in which the gripped element on the slide is a dowel pin and the jaws have cooperating cam surfaces for yieldingly gripping and releasing said dowel pin.
Claim 9
Dependent Claim
35 words
In a mold as described in claim 1, in which the gripped element on the slide is a dowel pin and the jaws have cooperating cam surfaces for yieldingly gripping and releasing said dowel pins.
