Description

one

The invention relates to foundry, in particular to the injection molding of nodes on machines with a horizontal extrusion chamber.

Closest to the invention of the known technical solutions is a device for pressing on injection molding machines, comprising a pressing chamber with a pressing piston and a pusher for removing the press residue. The pusher is placed in the bottom of the pressing chamber against the filling window and moves back and forth from the hydraulic cylinder when the press residue is installed against the filling window, the pusher rises and throws it up from the pressing chamber 1 J.

However, the known device does not have reliability, since the press residue may hang on the pusher, and this will require the use of manual labor of the caster to remove it.

laziness. All this leads to a decrease) P11o process performance.

The purpose of the invention is to show the performance of the process.

The goal is achieved by the fact that a device for pressing a metal, comprising a pressing chamber with a pressing piston and a pusher for removing a press residue, mounted at the bottom of the pressure chamber against a casting window with the possibility of reciprocating movement from the drive, is equipped with a press residual ejector, configured as a curvilinear lever pivotally associated with the pusher.

FIG. 1 is an illustration of a device, general view, in FIG. 2 shows section A-A in FIG. one.

The device comprises a pressing chamber 1, a pressing piston 2 connected to the press drive shaft 3. The pusher is made in vnde

rod} 1 1 4, one end of which is connected to the drive actuator 5, installed in the outer part of the device body, and the other, the free end is located in the hole in the bottom of the pressing chamber, flush with its inner surface and opposite the i410 window. The clutch 6 is mounted on the drive rod 4 and through the connecting rod 7 is pivotally connected with a tripper device, made in the form of a curvilinear lever 8.

The device works as follows.

After the metal is poured into the pressing chamber 1, the metal is pressed into the mold and the casting is formed, the pressing piston 2 lifts the press rod from the sprue system and returns to its original position. Next, the pushing-out mechanism of the press residue starts to work, the rod 4 through the filling window in the pressing chamber, in its upward movement, lifts the press residue, removes it from the pressing piston 2 and removes it from the working zone of the chamber. At the same time} a coupling 6, connected to the rod 4 through the connecting rod 7, leads to the curvilinear lever 8 (collide.tp-)), the latter having moved along

Spirgish, provides ud-cheli (discharge) of the press residue.

The press residue removal device operates synchronously with the ejection mechanism 5 and ensures reliable operation of the casting machine.
