[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] Depend on Figure 1-3 The utility model includes a base 1 and a molding mechanism 2, the molding mechanism 2 is installed in the base 1, a material tray 9 is arranged on the base 1, and a light-curing material can be placed in the material tray 9, a side plate 3 is installed on the base 1, a machine cover 4 is installed on the top of the side plate 3, and a building mechanism is arranged between the base 1 and the machine cover 4;

[0017] The construction mechanism includes two lifting components that are arranged opposite to each other on the left and right. The two lifting components can be plugged into each other, and the simultaneous lifting of the two lifting components can drive the dental model to rise and fall.
