Problems solved by technology
[0005] The object of the present invention is to propose a manufacturing method of an injection mold and a rotating body, which can solve the problem that the number and shape of the helical structure and the rotation angle around the axis of the rolling brush body are limited, and the strength of the rolling brush body is good, and the wall thickness is relatively thick. Thin, helps to reduce the energy consumption required to rotate the brush body

The invention relates to the technical field of injection molding, in particular to a manufacturing method of an injection mold and a rotating body. The injection mold is used to form a hollow rotating body, and the outer wall of the rotating body is provided with a first spiral structure. The injection mold includes: a mold body; a spiral forming mechanism, which is arranged on the mold body, and the spiral forming mechanism includes an outer core and an inner mold. core, when the inner core and the outer core are in the molding position, the inner core penetrates the outer core, at least a part of the molding cavity is formed between the outer core and the inner core, and the outer core is provided with a molding first The first helical forming structure of the helical structure; the driving mechanism is arranged on the mold body, capable of driving the outer core and the inner core to separate from the rotating body, and at least part of the first spiral forming structure is separated from the rotating body through spiral motion. The shape, quantity and parameters of the helical structure formed by the injection mold are not limited.
Description
technical field [0001] The invention relates to the technical field of injection molding, in particular to a manufacturing method of an injection mold and a rotating body. Background technique [0002] The vacuum cleaner is a cleaning device that uses a motor to drive the blades to rotate at high speed, and generates negative air pressure in the sealed housing to absorb dust. The vacuum cleaner is provided with a rolling brush, and the dust is raised by the rolling brush rotating and beating the ground, thereby improving the dust collection effect. [0003] The rolling brush includes a rolling brush body, and the rolling brush body is generally a solid structure, resulting in a large weight of the rolling brush body and large energy consumption when the rolling brush rotates. Part of the rolling brush body is a hollow structure, and the outer wall of the rolling brush body is provided with spiral structures such as convex ribs or grooves extending spirally for installing cl...
