Description

, one

The invention relates to foundry and can be used in die casting machines with a vertical press chamber.

A device for removing the pressure chamber on a press-pouring machine with a vertical pressing chamber is known, which contains a lever for removing the pressure of the rest, driven by the mechanism of locking the mold by means of two gear racks and a gear. A safety guard with a stand is fixed on the frame of the machine in order to maintain the movement of the press residue, ush; the role of the transport chute 1.

The known device has the following disadvantages: the pouring of the metal into the pressing chamber is possible only manually, since the design of the device makes it difficult to use casting devices; maintenance of the pressing chamber is difficult, since the lever for removing the press residue and its drive limit access to the pressing chamber.

The aim of the invention is to improve the service conditions of the injection molding machine.

This goal is achieved by the fact that the device for removing the press residue and pouring the metal is provided with a tray with a hole mounted above the pressing chamber with the possibility of moving in the horizontal direction from the rotate.

The drawing shows a device for removing a press residue and pouring metal on a casting machine under pressure with a vertical pressing chamber, a general view. The device comprises a tray 1 with a hole 2, mounted above the chamber 3 of the pressing machine, to be cast under pressure with the possibility of moving in the horizontal direction along the guides 4 with the help of an iriver 5, made in the form of a cylinder. On the machine bed 6, a pressing piston 7 and a transport chute 8 are located. In the pressing chamber 3, a piston 9 is installed, which pushes out the pressure rod 10.

The device works as follows.

Liquid metal from the casting device (not shown) enters the tray 1 through the opening 2 into the pressing chamber 3

Maschiny for lt under pressure. The pressing piston 7, moving downwards, presses the metal into the mold (not shown). After a certain holding time, the pressing piston 7 returns to

initial position, and the piston 9 gives

press residue 10 into hole 2 of tray 1. Actuator 5 horizontally moves tray 1 with press residue 10 to the right (according to the drawing) until press residue 10 drops out of hole 2 of tray I to trap channel 8, which sends it to the container. The space above the pressing chamber 3 is free and all maintenance (cleaning, lubrication) can be performed.

Tray 1 is then driven back to its original position 5 by the drive 5 to repeat the duty cycle.

The design of the device makes it possible to use casting devices on machines with a vertical pressing chamber, facilitates access to the pressing chamber during its maintenance, which leads to an improvement in the service conditions of the injection molding machine.
