[0002] Two-color molds are becoming increasingly popular in the market. This process can make the product look more beautiful and make it easier to change colors without spraying. However, it is expensive and requires high technical skills. A two-color mold is a mold in which two plastic materials are injected on the same injection molding machine and molded in two stages, but the product is only ejected from the mold once.

[0003] While current two-material injection molds can easily meet usage requirements, adjustments require significant changes to the mold's position, which is cumbersome and impacts production efficiency. Therefore, we have introduced a bottom mold structure, mold, and production device suitable for the production of two-color spoon bodies to solve these problems. Utility Model Content
