Abstract
Abstract An arrangement for guiding the movable plate of a horizontal press in a machine for casting metals in a chill mold is characterized by the plate being simply supported at the bottom, resting on two horizontal slides, and being suspended from above by rods from horizontal guiding columns of the machine along which it slides.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
140 words
In a machine for casting metals in a chill mold characterized by a horizontal press having a stationary die part, in which an injection tube is received, and a movable die Plate, the improvement comprising: a guide bed; a pair of horizontal slides on said guide bed for supporting said movable plate; a pair of horizontal guiding columns disposed above said movable plate and generally oriented in the same direction as said pair of slides; a pair of linking members being respectively pivotally secured at an upper end thereof to different ones of said pair of guiding columns and pivotally secured at a lower end thereof to opposite ends of said movable plate; whereby said movable plate is suspended from said linking members while being slidably supported on said horizontal slides to compensate for heat expansion of the die parts.
Claim 2
Dependent Claim

In a machine for casting metals in a chill mold characterized by a horizontal press having a stationary die part, in which an injection tube is received, and a movable die Plate, the improvement comprising: a guide bed; a pair of horizontal slides on said guide bed for supporting said movable plate; a pair of horizontal guiding columns disposed above said movable plate and generally oriented in the same direction as said pair of slides; a pair of linking members being respectively pivotally secured at an upper end thereof to different ones of said pair of guiding columns and pivotally secured at a lower end thereof to opposite ends of said movable plate; whereby said movable plate is suspended from said linking members while being slidably supported on said horizontal slides to compensate for heat expansion of the die parts.
Claim 3
Dependent Claim
58 words
A guiding arrangement as in claim 1, wherein the plane sliding surfaces of said horizontal slides and said movable plate are inclined so as to coincide with the main directions of expansion of said movable plate, with the result that the expansion is absorbed by the slipping of the lower end of the movable plate on the slides.
Claim 4
Dependent Claim
52 words
A guiding arrangement as set forth in claim 1, wherein said linking members are mounted with an inclination such that a departure from parallelism of said horizontal guiding columns due to intense heating of a fixed supporting plate does not cause malfunctioning of the movable plate with respect to the fixed plate.
Claim 5
Dependent Claim
29 words
A guiding arrangement as set forth in claim 2, wherein the planes of the sliding surfaces have an intersection passing through the center of expansion of said movable plate.
