  • Patent number: 10663202
    Abstract: A modular mold for making a hollow ice brick includes an external mold (1) and a mold core (2). The external mold (1) is a container that is formed by a bottom plate (11) and an enclosure wall (12) and that has an opening at the top thereof. The mold core (2) is located on the bottom plate (11) of the external mold (1). The bottom plate (11) and the enclosure wall (12) of the external mold (1) as well as the mold core (2) are spliced by modular mold sheets (3). The ice making mold adopts a modular design, is spliced by mold sheets and can be quickly assembled, and molds of different shapes and sizes can be formed according to requirements of a user. The formed mold includes the external mold (1) and the mold core (2); after a liquid is added in the external mold (1), a hollow ice brick can be formed when the external mold (1) is placed in a cold place.
