LENS BARREL ELEMENT, MOLDING DIE, CAMERA MODULE, AND ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/067694

Kind Code:

A1

Abstract:

The present application provides a lens barrel element, a molding die, a camera module, and an electronic device. The lens barrel element comprises a body portion and multiple gates; the body portion comprises a first end surface and a second end surface which are opposite; an accommodation hole running through the first end surface and the second end surface is formed on the body portion; the outer side wall of the body portion has a molded surface; during injection molding, the molded surface is used for being connected to a parting surface of the molding die; the multiple gates are formed on the molded surface; the multiple gates respectively correspond to sprue ports of the molding die. A molding material is injected into the gates through the sprue ports of the molding die to obtain the lens barrel element; the gates are located on the molded surface, and therefore, when a male die and a female die of the molding die are separated from each other, runner scrap of the molding material at the lens barrel element and the gates is separated at the same time, thereby saving the shearing processing process at the gates, saving the costs, and improving the automation degree of molding production and production efficiency.
