Abstract
A method and an associated apparatus for cleaning an inner wall of a mold part includes forming a chamber between displaced mold parts by introducing a casing between the mold parts. The casing enclosures a blasting device for introducing a blasting nozzle which directs a cleaning jet at the inner wall. The chamber encapsulates noise and particles which are produced during the cleaning process.
Claims21
Apparatus for cleaning an inner wall of at least one mold part of a mold having at least two parts which can be displaced relative to one another along an axis and, in a closed state, form a complete mold, comprising:
- a casing,
- a movable blasting device which has at least one blasting nozzle through which there emerges a cleaning jet which is directed against at least part of the surface of the inner wall and contains dry-ice pellets and a carrier medium,
- a supply unit which is connected to the blasting device via at least one supply line, and
- the casing and the blasting device constructed such that they can be introduced between the mold parts and the casing and the mold parts defining a chamber during cleaning.
