Heat insulating layer forming mold and method

The invention provides a heat insulating layer forming mold and a forming method. The heat insulating layer forming mold comprises a fixing device, a male mold fixing tool, a first male mold, a second male mold, an upper mold of a female mold, a demolding tool and a bottom mold of the female mold. The forming method comprises the following steps: during mold forming, fixedly connecting the second male mold and the first male mold through the male mold fixing tool; during demolding, removing the male mold fixing tool to remove connection of the first male mold and the second male mold, and fixedly connecting the second male mold and the upper mold of the female mold by using the demolding tool; fixedly connecting the upper mold of the female mold to the bottom mold of the female mold to form a barrel; and positioning and fixing a combined portion of the first male mold and the second male mold in the barrel through the fixing device to form a cylindrical gap with the barrel. 本发明提供了绝热层成型模具及方法，本发明提供的绝热层成型模具包括：固定
