AI Technical Summary
Common silicone molds cause inserted cores or spacers to shift during casting, leading to unsatisfactory results, and it is difficult to create a solid base and continuous patterns or openings in the finished piece simultaneously.
A multi-part silicone mold comprising an outer mold with integrated patterns and a core, and an inner mold with a corresponding recess, ensuring precise fitting to prevent shifting and allowing for the production of decorative pieces with bases and openings.
The mold design prevents core slippage, enables precise and reproducible production of decorative objects with bases and perforated walls, and allows for flexible design and easy handling.

Abstract
Description
Technical field
[0001] The invention relates to the field of casting and molding techniques, in particular silicone molds, which are used for the production of decorative items, figures or objects made of ceramic casting compound or comparable materials. State of the art
[0002] Common silicone molds typically consist of a one-piece negative mold into which a casting compound is poured. However, these molds tend to cause inserted cores or spacers to "float" or shift during the casting process, resulting in unsatisfactory results. Furthermore, it is difficult to simultaneously create a solid base and continuous patterns or openings in the walls of the finished piece. Object of the invention
[0003] A silicone mold is to be provided that allows for the safe and precise positioning of the mold parts during casting. The mold should ensure that the components do not float, while simultaneously allowing the production of decorative pieces with a base and optionally continuous openings or patterns in the walls. Description of the invention
[0004] The invention provides for a silicone mold consisting of at least two mold parts: 1. First mold part (outer silicone mold): ◯ This component has an outer wall into which any pattern can be integrated. ◯ The patterns later penetrate the workpiece in the form of openings. ◯ In the middle there is a protruding core that fits into the corresponding recess of the second molded part. 2. Second mold part (inner silicone mold): ◯ This component has a recess identical to the core shape of the first part, so that it can be fitted precisely onto the core. ◯ This plug connection reliably prevents the molded part from slipping or floating up during casting.
[0005] The shape of the core and the recess can be freely chosen (cylindrical, rectangular, other shapes), as long as both parts fit together exactly.
[0006] By joining the two mold parts, a closed mold cavity is created into which ceramic casting compound can be poured. In this way, objects can be cast that: • have a closed floor surface, • have lateral openings or patterns, • and can be manufactured with exact reproducibility. Advantages of the invention • Preventing the second mold from floating during the casting process. • Ability to produce decorative objects with floor and wall openings in a single casting process. • Flexible design of the shape through variably selectable core and opening geometries. • Easy handling and secure positioning of the molded parts thanks to the plug-in connection. • Reusable, durable silicone mold. Examples of implementation • Example 1: A cylindrical outer form with floral patterns on the walls and a central core. The inner form is fitted precisely over the core opening, so that after casting a decorative ceramic cylinder with a base and openwork side walls is created. • Example 2: A rectangular mold with geometric cutouts in the walls. A ceramic object with a closed base and side window openings is cast using the rectangular core in the middle and the matching counterpart. Summary
[0007] The invention relates to a multi-part silicone mold consisting of an outer mold with a core and an inner mold with a corresponding recess. The interlocking connection prevents the mold parts from slipping, thus enabling the reliable and precise production of decorative pieces with bases and perforated walls from ceramic casting compound.
