1. A manufacturing method of a quartz container, comprising:
providing a mold, a molding piece and a raw material, wherein the mold includes a top cylinder and a mold bottom connected with each other, the top cylinder is provided with an opening and the mold bottom is away from the opening, and the mold bottom is a cone;
forming the raw material into a first green body on an inner wall of the top cylinder through the molding piece in a case where a first included angle is formed between an axis of the mold and a horizontal plane and the mold rotates around the axis at a first rotational speed;
forming the raw material into a second green body on an inner wall of the mold bottom through the molding piece in a case where a second included angle is formed between the axis and the horizontal plane and the mold rotates around the axis at a second rotational speed;
and manufacturing the quartz container with a container green body composed of the first green body and the second green body;
wherein the molding piece comprises a first member, a second member and a positioning member; and
an end of the first member is connected with a first end of the second member, and the positioning member is installed at a second end of the second member; and the positioning member is matched with the bottom of the cone, so that the first member is matched with the inner wall of the top cylinder to mold the first green body, and the second member is matched with the inner wall of the cone to mold the second green body in a conical barrel shape; and
wherein the first included angle is greater than or equal to 45 degrees and less than or equal to 75 degrees, and the first rotational speed is greater than or equal to 60 revolutions per minute and less than or equal to 75 revolutions per minute.
