Various types of materials can be used to make a basket mold. For example, plastic, metal, glass, concrete, hardwood, sandstone and wood may all be suitable. The materials can be selected based on the purpose of the mold. For instance, a mold made for making a basketball basket is usually made of first-grade plastic, while a mold for producing a soap or chocolate basket might use hardwood, fiberglass or a combination of the two.
In general, a basket mold assembly consists of several components, including the bottom, top and side walls, as well as the requisite clips, bolts and throughbores. The bottom and top sections are typically carved out of a single piece of material, while the side walls are often removably held in place during the weaving process. Generally, the sides and the bottom are sized to produce the desired shape of the interior cavity. If the interior of the mold is to be a rectangular shape, for instance, then a mold with a relatively straight and narrow side wall would be needed.
The top section of the mold is typically carved out of a single piece, and includes a spindle hole. In some instances, the lid mold is the same as the body mold, but the top section is reversed. The top section is sized to match the octagonal top of the basket, and may include a recess for securing the woven top. The top rim of the basket is formed from a piece of material, which could be hardwood or other dense material. A soft wood base may be used to reduce the overall weight of the mold.
A multi-part mold is a better alternative. A glued up single piece of mold is cumbersome and costly. Moreover, a single mold cannot be fabricated in various sizes. The present invention allows the creation of a multi-part mold with separable sections, each secured together by a releasable fastening mechanism. This can be done by gluing the corresponding sections together, or by adding to or subtracting individual sections.
The name of the game is to have the requisite quantity of components in the correct order. For example, if you intend to create a basketball basket, then you will need a mold with a rim-side top, a front and back wall, a side wall, a bottom, and an inner band that defines the top edge of the basket. The bottom of the mold may be a wooden ring, or a plywood arrangement, which is not only inexpensive to manufacture, but provides structural stability. The aforementioned top section can also be provided with a counter-sunk bolt head hole for securing a wooden rim. A similar arrangement can be fashioned to support a soap or a wooden soap dish.
The same principle applies to the construction of an expandable mold. A plurality of individual mold sections can be glued or reglued into position, each sized to produce the shape of the interior cavity of the basket.
