Splash guard for mold shooting or blow molding machine

The invention relates to the splash guard Shooting "or blow molding machine",

To an ever greater extent, you see in practice the mechanical, pneumatic pore, in particular Core production by «

In the known methods used is made of the form »or, Keraaand by means of compressed air the machine in between the slide head and the table Pressed (shot) or blown molding box clamped using suitable devices

In practice it is umrenneIdIiOh ₉ that, due to the wear and tear of the contact surface of the core box, or because grains of sand get between the contact surfaces, compressed air escapes with each shot, dragging a small hinge of molding sand with it.

This sand spurts out at high speed and endangers the operating personnel or others

The disadvantage of this device is "that no inevitable shielding takes place «

One improvement of the mentioned device consists in making such an arrangement that the Tripping is only possible when the shield was operated »

With an automatic sequence of the SehleßYorganges has this arrangement also not proven itself «because the operator is involved in the exercise of τοη lifting
