Description

one

The invention relates to foundry, and more specifically to installations for casting large castings.

A known ingot casting machine has a foundation on which a rotating vertical shaft and a horizontally rotating table are fixed. When the rotary table is rotated, devices for successive tilting of the molds are activated to remove ingots from them and return the molds to their initial position for filling 1.

However, when using such a mask for casting large castings, it becomes difficult to remove cores, patterns and shapes. The support of the table, made in the form of a rotating vertical shaft, does not allow to mechanize the process., Removing models and rods. In this case, the process of extracting models and rods is a self-contained operation, which leads to an increase in transport operations, the labor intensity of manufacturing parts and reduces the performance of the maschine.

The aim of the invention is to increase productivity.

This goal is achieved by the fact that the installation is equipped with an ejector mechanism located under the central part of the table, and the table support is made in the form of a roller cassette that moves along rails attached to the frame. The ejecting mechanism is made in the form of a drive plate with fasteners attached to it, which enter into evenly made holes on the table surface.

FIG. 1 shows a general view of the installation; in fig. 2 - the same plan view.

The installation consists of a rotary table 1 rotating from the drive 2. The rotary table 1 rests on a roller cassette 3, which moves along a guide 4 fixed on the frame 5 resting on the foundation. On the table 1 there is a flask 6. Under the central part of the table there is an ejection mechanism 7, provided with a plate 8 with pins 9 fixed on it. In the table 1 along the axes of the holes there are holes 10 under the pins 9. To eliminate the possible movement of the turntable up along the perimeter The table has four support rollers 11, mounted on racks 12.

The operation of the installation is as follows.

The mold is placed on the turntable I. During the casting process, the mold is rotated in a horizontal plane. After the casting crystallizes, it is removed from the mold without further transport when the mechanism 7 is applied.

When changing the dimensions and configuration of the castings, the number of pins 9 as well as their location on the plate of the ejection mechanism 7 can be changed, which, in turn, makes it possible to obtain castings of a wide range and thus ensures the widening of the technological possibilities of the installation.

The introduction of the roller cassette, which was mixed along the guide, allowed the central part of the table to be released and the ejection mechanism located under it, which led to a reduction in the inter-transport unit. “Vydiak-vybiaka and increase the loss of labor.
