[0002] Wax casting, also known as lost wax casting, is widely used in the precision casting industry due to its convenience in mass production and precision consistency. It is the key to the molding of precision casting products. The wax mold tree assembly is to weld the product wax mold through the die head wax strip used for tree assembly and the wax runner die head.

[0003] The utility model with patent number CN201420673905.0 discloses a wax model tree branch. It includes a hanging head and a frame body connected to the hanging head in one piece. The hanging head is located on the axis of the frame body. The side of the hanging head and the side of the frame body are connected to a reinforcing strip in one piece.
