Definitions

  • the invention relates to a device and its essential parts for the electroplating, in particular for the electroplating of dental molded parts such as frameworks for crowns, inlays, bridges and the like, according to the preamble of claim 1.
  • Galvanic deposition i. H. the deposition under current flow, metallic layers has been known for a long time. If molded parts are formed, i.e. bodies that are stable in themselves, this is known as electroforming.
  • Electroplated gold layers have a much higher hardness than cast ones, which is between 60-80 HV or between 100-130 HV depending on the electrolyte composition. These electroplated gold layers are usually free of voids, inhomogeneities and contaminants, which are inevitable when casting. Nevertheless, it can be caused by improper work and due to the introduction of contaminants or manufacturer-related process fluctuations in the separation process. These show up e.g. B. by electroplating impurities, bud formation, layer formation or holes in the layer. In the worst case, such disturbances can lead to loss of firing stability and thus make the layers / moldings obtained unsuitable for further processing in dental technology.
  • the problem with the production of dental prostheses / dental molded parts by galvanic means lies in the sometimes complicated geometric shapes and the special precipitation properties that are required. For reasons of stability and processing technology, a uniformly homogeneous layer structure and a layer thickness distribution that is as uniform as possible are desirable.
  • the current-controlled galvanic deposits, as z. B. in the AGC ® devices of the applicant are significantly more reliable and deliver reproducible good properties.
  • These devices can usually be placed and operated on a simple work table, usually with a usable volume of electrolyte from about a liter or less, and a capacity of a few dentures, e.g. B. crown caps, which can be produced in one process.
  • the users of such electroplating devices are generally employed in a dental laboratory, for example dental technicians - that is, not specially trained personnel for electroplating. It is therefore important that such electroplating devices are easy and risk-free to operate, both with regard to the quality of the dental prosthesis manufactured therein and with regard to the health hazard to the operator. Therefore, the manufacturers of such electroplating devices endeavor to offer devices with the greatest possible user friendliness and process reliability. Examples include the AGC ® range of devices from the applicant, which covers, for example, capacities from 1 to 16 objects that can be galvanized simultaneously and process times from 1 to 16 hours.
  • the contact rods / holding rods are then connected to the current / voltage source in the device using a plug contact (e.g. a socket), a metal collet or a crimp contact. It is also important for contact with the device that it has a long service life and, if it is inside the electroplating cell, that it is not susceptible to corrosion. Corrosion products can contaminate the electrolyte and endanger the entire function of the process.
  • the operator establishes the contact, that is, equips the device with duplicate models and makes the electrical contact.
  • a disadvantage of the types of contacts mentioned is that contact resistances always occur, which can be undefined and, under certain circumstances, prevent sufficient current flow to the duplicate model to be galvanized. In such cases, there may be a failure in the galvanizing process, which manifests itself in the fact that the galvanized gold framework is too thin and / or the layer structure is disturbed, or in the extreme case the galvanizing process is completely prevented. In addition, the above-mentioned contacts are sometimes difficult for the operator to handle and the parts connected to each other are difficult to adjust.
  • the object of the invention is therefore to avoid or to largely rule out the problems associated with contacting in the prior art.
  • the parts to be galvanized or Models should be easily connectable to the current / voltage source, and this connection should be reliably maintained throughout the process time.
  • the electrical contact should also be able to be broken again in a simple manner in order to be able to introduce new parts / models into the electroplating device.
  • the device according to the invention has at least one current / voltage source and electrodes which can be arranged in a vessel which can be filled with an electrolyte. At least one magnetic connecting means between at least one electrode and the current / voltage source is provided for producing the electrical contact for the galvanic deposition.
  • the essence of the invention is based on the fact that a magnetic contact is provided for establishing the electrical contact between the electrode and the current voltage source.
  • the magnetic adhesive force of two electrical metal magnetic parts causes an electrical circuit to be closed by the corresponding contact of these parts.

  • Such a two-part design can a magnet as the first part and a second part made of a magnetizable metal.
  • the two-part magnetic connecting means consists of two magnets which, by their attraction, make the necessary contact. When using two magnets, a particularly good holding force and minimal contact resistance are achieved.

In such designs, the magnet associated with the current / voltage source is preferably arranged on this head or cover part. In this way, contact with the electrodes can then be made particularly easily.
