A vertical die cast apparatus having a novel docking/shot assembly in which the docking and docking cylinder and shot cylinder are constructed in one compound cylinder. A novel construction for supporting the docking/shot assembly is also provided.

Die casting machine with compound docking/shot cylinder

A metal die casting machine having a safety bar mechanism for cushioning the stopping action of a movable platen when it is stopped prior to reaching the closed position of the dies. One embodiment provides a two-part bar connected together by a cushioning means. A second embodiment mounts a cushioning means on one of the platens, preferably the movable platen.

Die casting machine with safety bar

The shot cylinder mechanism is moved from a position for receiving molten metal to an injection position wherein the molten metal is injected into the die cavity of the die casting machine, and vice versa. The shot cylinder mechanism is swung in open space from one position to the other as it is guided by a linkage system having a geometry that takes advantage of the constant speed of the cylinder to give faster, non-linear motion in moving from one position to the next and then at the end of the injection position, the proper force is exerted on the shot cylinder mechanism to provide a seal between the shot sleeve and the opening leading to the die cavity.

Vertical shot mechanism for die casting machine

A system and machine for squaring tie bars for die casting machines in which a detector means is provided for each of the tie bar nuts for separately and individually detecting the relative positions of the tie bar nuts of each of the tie rods whereby when the machine is originally squared by adjusting the adjustable means, the original squared positions of the nuts are detected and after operation of the machine it can be resquarded by adjusting said adjustable means to adjust said tie bar nuts back to their original squared positions. This adjustment is automatically accomplished through a logic circuit which controls the adjustment of the tie bar nuts.

Means for squaring tie bars for die casting machines

A clamping device used for mounting die sections on machine platens, the device including a support carriage slidably mounted on the platen and having a clamp arm thereon. Means is provided for advancing and withdrawing the carriage from a die section on the platen and for moving the engaging end of the clamp arm toward and away from the platen, the carriage and clamp arm being activated from the periphery of the platen. Preferably, a camming assembly is engaged with an advancement screw and is slidably mounted on the platen to shift with the carriage. The camming assembly and the carriage are biased apart, but converge when the carriage contacts the edge of the die section in order to cam the clamp arm onto the die section.
