Open casting mould with closable opening for optional embedding of an additional part

Abstract

Open casting mold (1), in particular made of flexible silicone, for producing castings in the DIY or home user sector, characterized in that there is at least one opening (4) in a wall of the mold (1) through which an additional part (10) can be inserted during the casting process, wherein the opening (4) can be temporarily closed by means of a precisely fitting plug (3) attached to the mold.

Description

[0001] Open molds for the production of decorative items are common in the DIY and home user sector. They are usually made of flexible material, especially silicone, and are used to create castings from resin, concrete, plaster, or similar media. However, these molds do not offer the option of selectively inserting external elements such as cords, wires, or rods into areas of the mold wall during the casting process.

[0002] In practice, additional work steps are often required for the subsequent fastening or suspension of castings. Ambitious users, for example, drill holes into the castings after curing and removal of the formwork to attach additional elements. This process is error-prone, as breakage or chipping can occur, particularly in brittle or thin-walled materials. Furthermore, drilling is time-consuming and requires additional, sometimes specialized, tools. Furthermore, the openings created in this way often need to be sealed with adhesives to permanently and securely fix the additional elements.

[0003] The object underlying the invention is to provide a casting mold with which additional elements such as wires, stems, or cords can be easily incorporated into the casting during the casting process, without the need for subsequent processing steps. At the same time, it should be ensured that the mold remains fully usable even without using this function, i.e., that a completely closed casting without openings can be produced.

[0004] This problem is solved by the features listed in claim 1.

[0005] The Fig. The open casting mold (1) shown in Figure 1 has a cavity (2) for receiving the casting material. In one region of the cavity, an opening (4) is provided that can be closed by a plug (3). This opening (4) forms an opening in the open state that is intended to receive an additional part (10). When not in use, the plug (3) is inserted into the opening (4) and completely closes the cavity (2) by means of the surface (5). The plug (3) is connected to the mold via an elastic connecting web (6). Fig. 2) and can be closed to create the cavity during casting.

[0006] After curing, the casting (9) with the form-fitting complementary part (10) can be easily removed from the mold via a demolding slot (7) on the outside of the mold. A targeted mold wall reinforcement (8) ensures that the mold remains dimensionally stable despite the demolding slot (7), even when the plug (3) is inserted or removed.

[0007] The invention ensures that the supplementary part (10) is securely and stably embedded in the casting (9) without the need for additional processing steps or fixation. The combination of the open mold design, flexible plug, and structural reinforcement allows for easy handling and reliable demolding with a high degree of accuracy of fit of the supplementary part.

[0008] An embodiment (schematic representation) of the invention is shown in the Fig. 1 to 3 explained.

[0009] They show: Fig. 1 the open casting mould (1) with cavity (2) and inserted plug (3), Fig. 2 the area of ​​the opening (4), the mold side of the plug (5), the connecting web (6), the demolding slot (7) and the mold wall reinforcement (8), Fig. 3 the cast casting (9) with embedded additional part (10).

Claims

[1] Open casting mould (1), in particular made of flexible silicone, for the production of castings in the DIY or home user sector, characterized by that there is at least one opening (4) in a wall of the mold (1) through which an additional part (10) can be inserted during the casting process, wherein the opening (4) can be temporarily closed by means of a precisely fitting plug (3) fastened to the mold. [2] Casting mould according to claim 1, characterized by that the plug (3) is permanently connected to the mold (1) via a flexible web (6). [3] Casting mould according to one of the preceding claims, characterized by that a vertical slot (7) extends from each opening (4) to the open casting side of the mold (1). [4] Casting mould according to one of the preceding claims, characterized by that the slot (7) enables the damage-free removal of a cast-in additional part (10). [5] Casting mould according to one of the preceding claims, characterized by that several openings (4) are provided in the mold wall, each of which is provided with an associated plug (3). [6] Casting mould according to one of the preceding claims, characterized by that the plugs (3) can be inserted into the openings (4) in a form-fitting manner so that no material leaks out during casting. [7] Casting mould according to one of the preceding claims, characterized by that the casting mold (1) has a reinforcement (8) at the locations of the openings (4) in the surrounding area of ​​the mold wall. This prevents the casting mold from losing its shape when the additional parts (10) are inserted into the opening (4) or during casting, or from the side wall opening in the area of ​​the slot (4).
