Definitions

• the present invention relates to a manufacturing method for enclosing an article in a multi-part and transparent shell mold and a transparent body with an enclosed article.
• optical effects such as a magnifying effect or enlarging or reducing effects are often used for the optical embellishment of gemstones.
• the basic principle is to insert and position an object in a transparent body, or in an envelope, and then to give optical effects by shaping processing, such as turning and / or polishing the transparent envelope.
• a manufacturing method for enclosing an article in a multi-part, provided at least partially transparent body In the method according to the invention, a first enveloping mold having a first joining surface and a second enveloping mold having a second joining face are provided. An object is aligned on or in the region of the first joining surface of the first enveloping mold. The first envelope shape and the second envelope shape are then brought together, so that the object remains between the first joining surface and the second joining surface or is temporarily clamped. In the event that the object is aligned in a defined position on the first joining surface, it can be achieved that it remains in this defined position when merging the first shell mold and the second shell mold.
• the first joining surface of the first enveloping mold is then fused to the second joining face of the second enveloping mold by applying a compressive force and a temperature to the first joining face and the second joining face, such that the first enveloping mold on the first joining face is in the second enveloping mold on the second joining face free from a visible seam.
• a transparent body having an enclosed article which has a first envelope shape with a first joining surface, a second envelope shape with a second joining surface, and the article itself.
• the first joining surface of the first enveloping mold can also be formed such that the article can be positioned on the first joining surface in a defined position.
• the first joining surface of the first enveloping mold and the second joining surface of the second enveloping mold are joined together in such a way that an area between the enveloping molds is free of a visible joining seam.
• a manufacturing method is provided with which arbitrary three-dimensional objects can be enclosed in a multi-part, transparent shell mold and aligned, or positioned and arise during the manufacturing process no annoying joint seams.
• the viewing angle is extremely important Accurate positioning according to the invention can be predetermined.
• various optical effects such as enlargements, reductions or distortions, can subsequently be generated by certain processing techniques, in particular turning and / or polishing techniques.
• the manufacturing method according to the invention is designed in a simple manner, so that can be dispensed with complicated control technologies or complex construction.
• three-dimensional objects are to subsume those bodies which have a greater height, width or thickness than approximately 0.1 cm.
• joint seam is understood to mean a dividing line of the respective shell shapes.
• the first enveloping mold, the second enveloping mold and the article are arranged in a guide shaft.
• these three elements in an upstream processing step for example, temporarily miteinender be connected to form a coherent structure, so that the object between the two joining surfaces is provisionally and temporarily fixed or clamped.
• the connection can be accomplished, for example, by means of an edge on one of the envelope form, which engages with an associated elevation on the other envelope shape, which will be discussed in more detail later.
• the guide shaft has a well-defined clear width, which is matched to the dimensions of the coherent structure of the shell shapes and the object, so that this contiguous structure in the guide shaft is very precisely movable adjustable.
• at least one plunger element moves into the guide shaft so as to apply a compressive force to the first envelope shape and / or the second envelope shape by means of retraction.
• the object has a surface that is aligned at right angles to a wall surface of the guide shaft.
• the surface of the object is also aligned at right angles to the movement in the guide shaft during the joining operation, whereby a displacement of the aligned object can be prevented.
• this area is also called "mirror”.
• the plunger element generates the pressure force parallel to the wall surface of the guide shaft. A displacement of the aligned object can thus be avoided, so that no unwanted transverse forces arise.
• a vacuum is formed before or during the fusion of the enveloping molds, whereby air pockets can be avoided.
• air pockets can be avoided.
• a clear or clear transparent envelope can be provided without disturbing the view of the pressed or welded article by, for example, air bubbles.
• vacuum formation can also reduce the required pressing force, which it is not necessary in this case, trapped air cushion compress. This also reduces the stresses in the joint seam, as there are no longer any air pockets under pressure.
• the object is centered on the first joining surface of the first shell mold, wherein the article is rotationally symmetrical. With a centered object, a uniform force distribution over the cross-sectional area of the joint seam can be achieved, so that no transverse forces occur that can move the aligned object during the joining process.
• the object is positioned in a volume-symmetrical manner in the radial direction relative to the first joining face of the first enveloping mold and the second joining face of the second enveloping mold. This ensures that during the melting process and the exertion of a compressive force no asymmetrical forces, or no lateral forces occur that would otherwise move the precisely positioned object in an arbitrary direction.
• the object is the same volume or the same mass of Hüllformmaterial, for example, in parallel acting compressive forces no change in the position of the object arise.
• an optical effect is achieved by means of machining, in particular by means of turning and / or polishing a first envelope surface of the first envelope shape and / or a second envelope surface of the second envelope shape.
• These envelope surfaces are understood to be the surface of the envelope shapes.
• a magnification effect may make a gem appear more precious or larger. Accordingly, reduction or distortion effects are also conceivable.
• the first envelope shape and the second envelope shape are produced by means of an injection molding process. Especially when using plastics or transparent plastics, in particular, the injection molding process is suitable for producing the basic forms or the shell molds.
• At least one of the joining surfaces of the two envelope forms is diamond-coated, so that the diamond-coated joining surface has a smooth surface.
• Diamond-cutting means producing a smooth surface, for example by means of diamond turning tools. This achieves an extremely smooth surface structure, comparable to a scarf-free polished surface. With this smooth surface a clear, invisible seam can be created.
• At least one of the joining surfaces of the two enveloping forms is processed so that a high-gloss, mirror-smooth, highly transparent surface is formed. With this surface, a joining seam can arise, which does not produce reflections of any roughness and is therefore not visible.
• one of the two envelope shapes may have an edge running around at least in sections, with the other envelope shape having an elevation.
• the two envelope shapes can then be brought together in such a way that the edge is positively engaged with the elevation.
• the first envelope shape and the second envelope shape are thus positively connected and stabilized in connection, wherein an object can be positioned and fixed accurately inside. In the subsequent joining process or during the fusion, the object can be better kept in its aligned position.
• At least the edge of the first envelope shape or second envelope shape and / or the elevation of the first envelope shape or second envelope shape is conical.
• the edge of the first or second shell mold has openings to allow the escape of air.
• air trapped in the interior of the enveloping molds can thus escape, so that no air bubbles can form on melting and thus a clear, transparent material composition can form.
• the article is oriented by centering the article in the first or second envelope shape by means of a positioning die which approximately images the article to position it therein. If, for example, the object rests on the first joining surface of the first enveloping mold, by means of the positioning mold, for example in the second joining face, while the enveloping molds move toward one another, the article can move into the positioning mold and thus align.
• the first cladding mold and the second cladding mold are heated to assume a doughy state.
• a pasty state the most viscous transition region between the solid and liquid state of aggregation of a medium is understood.
• the latter also has a fastening element for fastening to a holder element.
• the holder element can be selected from the group consisting of fountain pens, pens, watches and jewelry.
• a temperature of 120 ° C to 160 ° C, preferably about 140 ° C is selected during fusing.
• the temperature should be for a period of 1 to 5 seconds, preferably maintained for 3 seconds.

• the enveloping forms 1, 2 and / or the object 3 may be rotationally symmetrical.
• a volume symmetry with respect to the first joining surface 4 and / or the second joining surface 5 can be generated, so that identical volume fractions predominate. This results in a constant hydrostatic pressure during the pressure and melt phase along the joint seam, so that no transverse forces arise due to the applied pressure, which could cause the object 3 to leave its defined position during the joining process.
• FIG. 3 shows a further schematic view of the first and second enveloping molds 1, 2.
• the object 3 is introduced into the positioning mold 7 in the first joining surface 4 of the first enveloping mold 1.
• the collection of the first envelope 1 as well as the edge 6 'of the second envelope 2 is formed conically, whereby a press fit, or a positive connection can be formed, the both first and second shell molds can remain in the merged position and thus allows easier handling of the enveloping body and a more accurate positioning.
• FIG. 4 shows a three-dimensional view of the first enveloping mold with a first joining face 4, in which a positioning projection 7 of the object is provided.
• Fig. 5 is a three-dimensional view of the second envelope shape is shown, the edge of which has 6 openings through which air can escape during the pressing and melting process.
• FIG. 6 shows schematically a product produced by the method according to the invention.
• a one-piece body 10 produced after melting and pressing comprises an object 3 such as a diamond.
• the body 10 formed from the enveloping molds 1, 2 may be processed, for example rotated and / or polished, such that a certain optical effect, such as an enlarging or reducing effect, by means of a certain geometry and surface finish such as a turning and / or polishing machining is generated.
• a certain optical effect such as an enlarging or reducing effect
• a certain geometry and surface finish such as a turning and / or polishing machining
