Three-dimensional pastry forming device

The invention relates to the technical field of food processing, in particular to a three-dimensional modeling pastry forming device which comprises at least two mold blocks, each mold block is connected with a power device, the power devices are used for driving the mold blocks to move from a first position to a second position, and the mold blocks are provided with profiled grooves; when all the mold blocks are located at the second position, the grooves are spliced to form a cavity for forming pastries. After the spherical cakes are conveyed to the middle positions of the mold blocks, the corresponding mold blocks are driven by the air cylinders to get close to each other to move to the second position, and the mold blocks are spliced at the center, so that the spherical cake blanks are extruded in the mold, and the mold cavity is filled with the spherical cake blanks. And then the cylinders are used for driving the corresponding mold blocks to move away from each other to respective first positions, and t
