Abstract
The invention provides a sprayer for spraying mold wall treatment agent or another liquid. The liquid is sprayed onto, for example, the walls of a mold or some other article. The sprayer includes a spray element body and a rotor mounted with freedom to rotate around an axis of rotation in the spray element body. An atomizing element is attached to one end of the rotor. A first feed line for mold wall treatment agent or another liquid to be sprayed is provided, as well as a second feed line for control air which directs mold wall treatment agent atomized by the atomizing element in the desired spray direction.
Claims19
A sprayer for spraying mold wall treatment agent on the walls of a mold comprising:
- a spray element body;
- a rotor mounted with freedom to rotate around an axis of rotation in said spray element body;
- an atomizing element attached to one end of said rotor;
- a head portion movable relative to said atomizing element and positioned about said rotor;
- a first feed line for mold wall treatment agent;
- a second feed line for control air which directs mold wall treatment agent atomized by the atomizing element toward mold walls to be sprayed;
- an outlet of the control air feed line is located proximate an outside circumference of the atomizing element;
- wherein an adjustment of a position of said head portion adjusts a discharge amount of said control air.
A spraying element for preparing the walls of a mold for the molding or shaping of a molded part comprising:
- a sprayer body;
- a rotor rotatably mounted in the sprayer body;
- an atomizer integrally connected to said rotor;
- a mold wall treatment agent feed line positioned to supply mold wall treatment agent to said atomizer;
- a control air feed line in said sprayer body and having an outlet proximate said atomizer;
- wherein said control air feed line supplies air for urging atomized mold wall treatment agent in the direction of a mold wall to be treated.
