System for actuating a two part mould forming two mutually articulated half-moulds

An actuation system for opening and closing a two-part mold comprising first and second mold parts movably mounted to each other, the system comprising:

• a carriage which can move in each of two directions;
• a first pivoting part coupled to the first mold part;
• a second pivoting part coupled to the second mold part;
• at least one actuating member connected to each of the carriage and at least one of the first and second pivoting parts;
• a first connecting member having one end that is movably connected to the first pivoting part about a first axis and another end that is movably connected to the first mold part about a second axis;
• and
• a second connecting member having one end that is movably connected the second pivoting part about a third axis and another end that is movably connected to the second mold part about a fourth axis,
• wherein, in the closing position, the first, second, third and fourth axes are approximately in line with each other.

A mold system comprising:

• a plurality of two-part molds each comprising first and second mold parts;
• a plurality of carriages which can move in each of two directions;
• a plurality of first pivoting parts each coupled to the first mold parts;
• a plurality of second pivoting parts each coupled to the second mold parts;
• a plurality of actuating members each connected to a respective carriage and a respective two-part mold;
• and
• a cam which causes movement of each carriage depending on a rotational position of the respective two-part mold relative to the cam.

A system for opening and closing a two-part mold comprising first and second mold parts movably mounted to each other, the system comprising:

• a carriage slidably mounted to rails;
• a first pivoting part movably mounted to a first cylindrical member;
• a second pivoting part movably mounted to a second cylindrical member;
• a first connecting member connecting the first pivoting part to the first mold part;
• a second connecting member connecting the second pivoting part to the second mold part;
• a first actuating member connected to each of the carriage and the first pivoting part;
• a second actuating member connected to each of the carriage and the second pivoting part;
• the first actuating member being pivotally mounted to the carriage about a first axis;
• and
• the second actuating member is pivotally mounted to the carriage about a second different axis,
• wherein movement of the carriage in one direction causes the opening of the two-part mold and wherein movement of the carriage in another direction causes the closing of the two-part mold.

A system for opening and closing a two-part mold comprising first and second mold parts movably mounted to each other, the system comprising:

• a carriage slidably mounted to rails;
• a first pivoting part movably mounted to a first cylindrical member;
• a second pivoting part movably mounted to a second cylindrical member;
• a first connecting member connecting the first pivoting part to the first mold part;
• a second connecting member connecting the second pivoting part to the second mold part;
• a first actuating member connected to each of the carriage and the first pivoting part;
• and
• a second actuating member connected to each of the carriage and the second pivoting part,
• wherein movement of the carriage in one direction causes the opening of the two-part mold and wherein movement of the carriage in another direction causes the closing of the two-part mold, and
• wherein the first connecting member has one end that is movably connected to the first pivoting part about a first axis and another end that is movably connected to the first mold part about a second axis, wherein the second connecting member has one end that is movably connected the second pivoting part about a third axis and another end that is movably connected to the second mold part about a fourth axis, and wherein, in the closing position, the first, second, third and fourth axes are approximately in line with each other.
