Abstract

The casting chamber is designed for counter-pressure casting machines. It reduces the force loads on the parts and the required manufacturing accuracy, and simplifies the assembly of the casting mold. The casting chamber consists of a movable plate (1) with at least one power displacement mechanism (2) mounted on it, carrying a plate (3), to which are attached stems (4), connected to a movable part (5) of the casting mold. The stems (4) have channels (7) for supplying cooling fluid to the cooling circuit of the movable part (5) of the casting mold, which is placed in the space between the movable plate (1), casing (8) and the fixed plate (9) of the machine. The casing (8) is pressed and sealed onto the fixed part (10) of the casting mold, located on the fixed plate (9) of the machine. Channels (11) for cooling fluid are formed in the stationary part (10) of the casting mold.

Description

The invention relates to a casting chamber for a foundry machine is a counter pressure finding application in metal casting.

PRESCRIBED © the state of the art

A cast iron chamber for counterpressure casting (1) is known, which includes a sub-plate driven on the columns of the machine, a fixed plate, screwed into the machine columns by slots therein, a cylindrical casing made up of separate parts. a foundry mold consisting of a movable and a fixed part. The fixed part of the mold is fixed with bolts ksh the fixed point of the machine.

and the movable part of the Foundry Form to the movable plate of

the machine.

Before the casting machine is filled, the movable plate of the machine is pressed is a preliminary force that passes through the housing of the casting chamber to create a contact pressure in its seal, and then through the casting mold. The pre-molded tray is selected so that the subsequent deformation of the elements located on the force path from the force of the gas pressure does not disturb the hip and the casting chamber and does not remove the two parts of the casting mold.

A major disadvantage of the known casting chamber is that, in order to prevent the casting mold from being opened when generating gas pressure, the machine has to be pre-stressed with considerable effort, which in turn leads to an increase in the size of the machine in the casting part, so that it can absorb the resulting gas pressure.

2.

Another disadvantage is the need for a precise guide of the casting mold, due to the need for simultaneous pressing of the shape and parts of the casing.

Another disadvantage is that from a certain point until the two parts of the casting mold are pressed, the movable plate of the machine and the movable part of the casting mold are guided at the same time by the respective columns - the machine and the shape · If these columns are not parallel, result in deformation of the more unstable element and accelerated wear ·

The disadvantage is the difficulty in attaching the movable part of the casting mold to the movable plate of the machine, due to the presence of a casing, through the piping pass the piping for cooling the movable part of the casting mold. In addition, any bolts should be loosened and tightened every time next to other hot parts, to fix the fixed part of the casting mold, I give the fixed plate to the machine ·

TESCHWA NATURE

It is an object of the invention to provide a die-casting chamber for a counter-injection molding machine in which the force loads on the workpiece are reduced and the necessary precision of workmanship is facilitated by the assembly of the casting mold.

The problem is solved by a casting chamber for an anti-pressure casting machine comprising a fixed plate »a movable plate and a casing, between which a foundry mold consisting of a movable and a fixed part is marked, and according to the invention, the movable part of the mold is attached by means of stems to the plate , which is connected, give the movable plate of the machine by means of at least one power-shifting mechanism.

According to one preferred variant, the power displacement mechanism is a power cylinder.

In another embodiment, the stems have slurries to supply the cooling fluid to give the cooling circuit of the movable part of the casting mold ·

In a suitable embodiment, the housing is pressed and sealed on the fixed part of the casting mold.

In the stationary part of the casting mold there are molds for cooling fluid.

Another advantage is that the miserable part of the casting mold does not attach to the fixed plate of the machine.

Another advantage is that the fixed plate of the machine does not lock the machine's xmm columns which do not weaken from the necessary gaps.

DESCRIPTION OF THE APPLIED FIGURE

The accompanying figure is a sectional view of a casting mold of a casting mold as part of a counter-molding machine.

USE OF IMAGING

The movable plate 1 is sealed, which secures it through the housing 8 and the fixed part 10 of the foundry farm to the fixed plate 9 of the machine. The hydraulic cylinders 2 move the plate 3 down, which, by means of the stems 4, presses the movable clean 5 ksh fixed part 10 of the casting mold.

.............

After the casting, the hydraulic cylinders 2 move up the plate 3 at a distance X ^ from the stroke and the hydraulic cylinders 2, whereby the molding is removed. · After opening the casting machine, the second part of the stroke of the hydraulic cylinders 2, respectively, is made. 3 off etc. * ^co ® ^it smashing mechanism 6 abuts the movable plate 1 and differences are killed.
