(54) PLATE FOR SANDATED MACHINES

one

The invention relates to a foundry industry, in particular sandblasting machines for the manufacture of casting cores and molds.

Plates for sandblasting machines are known, for example, inflatable, or model-shaped, sotsderzhayas frame, in the inner cavity of which, communicated with the atmosphere, installed support and ventilation plates and spacers with replaceable workers and ventilation elements.

In order to improve the ventilation capacity of the slab, in order to improve the quality of the rods and shapes in the walls: 1 the casing of the bushings was filled with through-holes, together with the cavity of each spacing sleeve with an internal strip pa.JbI.

 In addition, the ventilation plate is mounted in the vice of the set of plates, tight

pressed to each other and provided on one side with a serrated notch forming channels of the air outlet.

FIG. 1 shows the proposed I plate with a nozzle, a cut; in fig. 2 times-

i cut along aa in fig. one; pas figs. 3 - rae cut by BB in FIG. 2. The naduvny plate consists of the frame 1, the ventilation plate 2 fixed in the frame, for example, by welding along the contour and the base plate 3.

In the vents of the vent plates 2, the spacer sleeves 4, made with openings in which the workers 5 (blown) or vent 6 elements are freely inserted, are installed and fixed, for example by welding. The spacer sleeves 4 are located in the ventilation plate. 2, in the coordinate grid and when installing workers 5 or ventilation 6 elements in them, their location is chosen which is the most optimal for each particular case.

Al Jments 5 and 6 are equipped with elastic sealing rings 7 to prevent the mixture from the core-chic cavity (form) (not shown in the drawings) from entering the internal cavity B of the plate. Ventilation elements 6 are provided with vents 8. Support plate 3 made with openings 9 located coaxially with spacer sleeves 4 and serving as a means of transferring the mixture from the nozzle 10 through working elements 5 to the core box (form) .. Ventilation plate 2 made in the vice set of plates 11, provided on one side with a toothed-notched i Surfaces with notched every plate 11 are tightly pressed to the smooth side of the adjacent ones: the plates and form channels 12 of the air outlet into the internal cavity-B through which and open T1t in spacer sleeves 4 and ventilation elements 6 also enters the internal cavity. Air holes from the cavity B are served by holes 13 in the frame 1. PuiZ.

Claims (2)

1 i Claims of the invention 1. A plate for sandblasting machines comprising a frame, in the internal cavity of which, supporting and ventilation plates and spacers with interchangeable working and ventilation elements, are installed with the atmosphere in order to improve ventilation capacity to increase the quality of the rods and shapes, through the holes in the walls of the spacer sleeves, indicating the cavity of each spacer sleeve with the internal cavity of the frame. 2. A plate according to claim 1, wherein the ventilation plate is made in the form of a set of plates; tightly pressed to each other and provided on one side with a serrated notch forming channels for air to escape. iTXxNX - l s OC yii | mshshsh FIG. 2 5 B
