Description: Electrically heated funnel spring as a wax knife and material storage for the waxing technique:

Waxing or modeling with hard wax is mainly carried out in dental practices and laboratories in order to Denture manufacture to shape the necessary tooth cusps. In other areas such as in goldsmith art also jewelry forms previously made as wax models, and similar to the dental technique with plaster of paris or ceramics: - material poured over. The wax is then hardened out of the Form melted out, whereby a hollow form arises in which then in turn the metal or other substances for the final Mold to be poured.

The devices currently used for the wax-up technique, so-called wax knives, are placed over a Bunsen burner warmed up. The hot probe is then dipped into the wax until a certain amount (a drop) forms with which shapes (such as cones or spheres) can be modeled. The modeling probe of the wax knife must always be used for this held over the flame again to heat it up again. With electrically heated modeling knives (modeling probes) this is no longer necessary. However, it has to be constantly immersed in the wax in order to be able to use liquid material available for processing.

In the case of electrically heated modeling knives, the temperature can be regulated so that the wax temperature is precisely at the flow or. Draw limit is kept. A constant immersion is _a uch here, when using conventional probes unavoidable.

In the arrangement embodying the invention, an electrically heated wax probe (1-1c) is shown which at the same time contains a material storage (liquid wax storage) (2 - 2c) and for quick and easy pulling of wax cones is particularly suitable. The majority of the basic forms to be grown up In railway medical prosthesis technology, it consists of cones of various sizes.

When using the funnel spring, the wax is filled in solid form into the storage funnel (2 - 2c), whereby it is poured through an electrically adjustable heater (5? 5a) to the desired Temperature is brought. The liquid wax occurs exactly as in an ink pen (eapidograph) at the end of the tube (3 -3c) and can thus target about 20 cones with a single Wax filling can be used »

The currently common method without wax storage takes a lot of time to form the cone.

With the arrangement described here, a cone can be produced in a single drawing process. Wi _e already mentioned, extends a storage charge for the production of about 20 cones from ·
