AI Technical Summary
Existing molds are difficult to manufacture irregularly shaped stones of various shapes. A single mold can only produce stones of one shape, which cannot meet the diverse needs of sand table models.
A sand table auxiliary mold was designed, comprising a transparent circular plate and a screw seat. By combining the screw and the steel ring, the shape of the steel ring can be changed by varying the screw's screwing depth and number, thus enabling the manufacture of stones of various shapes.
It enables simple and effective modification of mold shapes, allowing for the easy manufacture of stone models in various shapes to meet the diverse needs of sand table models.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of models, especially sand table models. Background Technology
[0002] In the process of creating a sand table, some irregularly shaped pieces are needed. For example, clay can be used to make stones for paving roads, or clay can be used to make decorative blocks for wall coverings. The creation of such models typically requires stones of different shapes, and multiple stones of each shape. Existing molds for creating such stones make it difficult to change their shape; a single mold can only produce one shape. This is similar to how a mold for making mooncakes can only produce mooncakes with one pattern. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, this utility model proposes a sand table auxiliary mold, including a screw. Six screw seats are bonded to the upper surface of a transparent circular plate along the circumference. Each of the six screw seats is provided with a corresponding screw. The axis of the screw points to the axis of the transparent circular plate, and the screw and the upper surface of the transparent circular plate are parallel. A closed steel plate ring is also provided. The lower side of the steel plate ring contacts the transparent circular plate. The steel plate ring is formed by closing steel plates of constant width. The screw is used to press against the steel plate ring, causing the steel plate ring to deform. The screw seat is made of metal and is composed of vertical and horizontal plates in an L-shape. The horizontal plate is bonded to the upper surface of the transparent circular plate, and the vertical plate is perpendicular to the horizontal plate. The vertical plate is provided with a threaded hole for the screw to be screwed in or out.
[0004] Furthermore, at least one screw has a different length than the others.
[0005] Furthermore, the steel sheet used to make the steel ring has a thickness of 0.2-0.5 mm.
[0006] Furthermore, the number of screw seats is three or more but not more than six.
[0007] This utility model has a simple structure and can be easily changed in shape. Attached Figure Description

[0011] See appendix Figure 1 This is a top view of the present invention, showing its structure. Figure 2 This is a horizontal view, focusing on the structure of the screw seat 2. A sand table auxiliary mold includes a screw 3. Six screw seats 2 are bonded to the upper surface of a transparent circular plate 1 along the circumference. Each of these six screw seats 2 has a corresponding screw 3, meaning there are six screws 3. The screws 3 are made of metal, and their axes point towards the axis of the transparent circular plate 1. The axis of the screw 3 is parallel to the upper surface of the transparent circular plate 1. A closed steel ring 4 is also provided. The lower side of the steel ring 4 contacts the transparent circular plate 1. The steel ring 4 is formed by closing steel sheets of constant width; therefore, the plane containing the upper side of the steel ring 4 is parallel to the upper surface of the transparent circular plate 1. The screw 3 is used to hold the steel ring 4 in place. Tightening it in or out can deform the steel ring 4 because the screw 3 applies pressure to the steel ring 4, forcing the steel ring 4 to deform. The screw seat 2 is made of metal and is composed of a vertical plate 22 and a horizontal plate 21 in an L-shape. The vertical plate 22 and the horizontal plate 21 are fixedly connected. The horizontal plate 21 is bonded to the upper surface of the transparent circular plate 1. The vertical plate 22 and the horizontal plate 21 are perpendicular. The vertical plate 22 is provided with a threaded hole 23 for the screw 3 to be screwed in or out.
[0012] In order to allow the steel sheet to have different deformation in different places, screws 3 of various lengths can be set. The screwing distance can change the shape of the steel sheet ring 4. For example, at least one screw 3 has a different length than the other screws 3.
[0013] The steel ring 4 should not be too thick or too thin. If it is too thick, it will be difficult to deform; if it is too thin, the shape of the steel ring 4 will be difficult to determine. The thickness of the steel sheet used to make the steel ring 4 should be 0.2-0.5 mm.
[0014] Different scenarios have different requirements for the shape of the stones, so the number of screws 3 is not necessarily six. However, the actual object manufactured by the inventor has six screw seats 2. In fact, the number of screw seats 2 can be more than three but not including six, such as 3, 4, 5, 7, 8, 9, etc. These numbers are within the scope of design.
[0015] Instructions for use: Place the steel ring 4 in the area enclosed by the end of the screw 3, ensuring the lower side of the steel ring 4 contacts the transparent circular plate 1. Then, screw different screws 3, pressing them against the outer side of the steel ring 4 to apply pressure and deform it. Different screw depths will result in different shapes of the steel ring 4. Fill the area enclosed by the steel ring 4 with modeling clay. Then, flip the transparent circular plate 1 to check if the bottom of the clay meets requirements, such as avoiding large air bubbles. Then, tap it gently to release the clay from the mold formed by the steel ring 4. Repeat this process to obtain the same stone model. If a different shape of stone model is needed, change the depth of the screw 3 to obtain a mold for that shape.
[0016] This invention has a clever design and simple structure, and the components needed for sand table manufacturing can be easily obtained.
