Description

one

The invention relates to foundry and can be used in the manufacture of shell molds.

Since sintering (curing) of a layer of thermosetting clad mixture applied to a model heated to a predetermined temperature is used as the basis for the manufacture of the 5-hole half-molds, it is an important factor to maintain the desired temperature of the model, which ultimately determines the performance of the equipment. It should be noted that the most intensive heat removal from the model occurs during the formation of half-molds.

The famous carousel for the manufacture of shell half-molds, comprising a multi-position rotary platform 20, a model tooling mounted on a rotary platform, and devices located at respective positions for forming curing and removing the fabricated shell half-molds Cf.

The disadvantage of such a machine is the lack of heating of the model equipment at the formation positions and pulling out the mold half, resulting in 30

it is necessary to overheat the models in the furnace, which degrades the quality of the mold halves and reduces the productivity

In order to increase productivity, the machine is equipped with devices for heating the model equipment located under the turntable at the forming and removing positions of the shell half-molds, and the device for heating the model ornament is installed; the position of the forming machine is not driven.

FIG. 1 shows the proposed machine, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 — node G in FIG. 1 (shaping position). , ,,

The machine is made as follows.
