[0002] A solar crucible is a device that uses solar energy to melt objects. It uses a reflector to focus solar energy onto a small point and heat the object to the melting temperature, thereby achieving processes such as melting and heat treatment. This type of equipment is particularly important in the photovoltaic industry, especially as a key component of a polysilicon casting furnace for solar cells. During the production process, the equipment needs to melt materials such as quartz sand at high temperature and use a mold for cooling and molding. Molding equipment is required during production.

[0003] In the prior art, such as publication number CN212720832U, a molding device for producing and processing solar crucibles is disclosed, which includes a melting furnace, a shell, a first motor, a drive box and a limit box, the melting furnace is rotatably connected to the inside of the shell; the bottom of the first motor is fixedly connected to the inner bottom surface of the shell, and the output end of the first motor is fixedly connected to the bottom surface of the melting furnace; a second motor is arranged inside the drive box, and the output end of the second motor is fixedly connected to a transmission gear train, and a first connecting shaft is welded on the side of the outer wall of the shell close to the drive box, and the first connecting shaft is fixedly connected to the end of the transmission gear train. The utility model melts the solar crucible through a melting furnace, a mold and other structures, rotates the melting furnace through the first motor, adjusts the tilt angle of the shell through the second motor and the transmission gear train, and controls the operation of the whole device through a control panel. The whole device has strong adjustment ability and is easy to operate, which can effectively improve the production efficiency and production quality of the solar crucible.
