Embodiment Construction

[0026] Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings. The embodiments are not intended to limit the invention but are examples, and all the features and combinations thereof described in the embodiments are not necessarily limited to the essence of the invention. The same or equivalent structural elements, components, and processes shown in the drawings are given the same reference numerals, and overlapping descriptions are appropriately omitted. In addition, the scale and the shape of each part shown in each drawing are set conveniently for the sake of easy description, and are not limitedly interpreted unless otherwise mentioned. In addition, even if it is the same member, there may be slight differences in scale and the like between the drawings. In addition, when terms such as "first" and "second" are used in this specification or technical solutions, unless otherwise specified, they are not terms indica...

Abstract

The present invention provides a mold device and a resin part, which reduce the occurrence of molding defects of the resin part. A mold device is a device for molding a resin part. The resin part is an elongated body and has: a first end, a second end, a first recess extending around the axis of the resin part near the second end, and extending axially to the first end in the second end. The second recess near the recess. The mold device has a mold forming a molding space. The mold has: a gate for injecting molten resin connected to a first region corresponding to the first end of the molding space; a first protrusion close to a second region corresponding to the second end of the molding space The second convex portion is arranged in the second region; and the third convex portion extends from the front end of the second convex portion toward the first region side. The tip of the third convex portion is located on the side of the first region rather than the first convex portion.

Description

technical field [0001] The present invention relates to a mold device and a resin part, and particularly relates to a mold device for manufacturing a resin part used in a vehicle lamp and a resin part manufactured by the mold device. Background technique [0002] Conventionally, various components have been used in lamps such as headlights of automobiles. In addition, each member is manufactured by various methods according to its shape and material. For example, automotive lamps have a calibration device for adjusting the direction of the optical axis serving as a reference for the direction of light irradiation. The alignment device is provided with a member called an optical axis adjustment screw for adjusting the optical axis. Optical axis adjustment screws are also called alignment screws. [0003] The optical axis adjustment screw may be entirely made of metal in order to ensure mechanical strength, but from the viewpoint of weight reduction, components using resin ...
