Open casting mold with integrated thread guide for the production of joined cast objects.

Abstract

Open casting mold (1), in particular made of flexible silicone, characterized in that it comprises at least one main cavity (2) and an additional cavity (3) which can be connected to each other by an inserted cord or wire (5), wherein the cord (5) is guided over incisions (4) arranged in the mold wall (6).

Description

[0001] Open molds made of flexible silicone are frequently used in the creative sector for the production of decorative cast objects.

[0002] However, known forms only allow the production of separate individual parts or completely closed / connected castings.

[0003] The targeted integration of connecting elements such as cords, threads or wires during the casting process is not yet known.

[0004] In practice, decorative or functional connections are therefore usually made afterwards by drilling, gluing or mounting.

[0005] These processes are time-consuming, imprecise, and carry the risk of material damage to the cast parts.

[0006] The invention is therefore based on the objective of providing a silicone mold with which multi-part cast objects connected by threads or wires can be produced in a single operation.

[0007] The mold should be easy to use, reusable, and suitable for various casting materials.

[0008] This problem is solved by the features mentioned in claim 1.

[0009] The in Fig. 1 The silicone mold shown (1) has a main cavity (2) and at least one additional cavity (3).

[0010] The mold walls (6) have incisions (4) and guide grooves (12) through which a cord or wire (5) can be passed.

[0011] The cord rests on a support surface (7) and in guide grooves (12) and extends into the cavities (2)(3). The cuts in the mold wall ensure a tight seal of the cavities, even with the cord inserted. The guide grooves define the position of the cord and ensure a slightly pre-tensioned pouring situation.

[0012] When the casting material (8, 9) is poured in, the cord (5) is also cast in, so that after hardening a connected cast object (10, 11) is created.

[0013] The mold is designed as an open casting mold and, due to the elasticity of the silicone, allows for easy insertion of the cord and demolding of the composite objects.

[0014] When demolding, the objects can be removed together, and the cord can be easily detached due to the open, outward-facing incisions.

[0015] In Fig. Figure 2 shows the silicone mold (1) with the cord (5) inserted.

[0016] in Fig. 3 the mold during the casting process with filled cavities (2, 3) and embedded cord (5).

[0017] Fig. Figure 4 shows the formed object: The outer frame (10) holds the cord (5), which connects the inner object (11) in a floating manner.

[0018] Another embodiment provides a multi-part, horizontally closed mold. In this embodiment, two mold halves are placed on top of each other, with the cord (5) being inserted into lateral guides or slots of the lower mold half.

[0019] The upper half of the mold then closes the cavities, creating the complete casting mold.

[0020] The cord lies in the separation plane, thus achieving precise guidance and sealing.

[0021] The invention makes it possible to create aesthetic, form-guided line connections between several cast objects without post-processing - a new method in the field of creative casting techniques, which I summarize under the proper name "MoldLineArt".
