Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of vehicle plastic parts processing molds, specifically relating to the inclined top mechanism of a vehicle rearview mirror bracket processing mold. Background Technology
[0002] A rearview mirror bracket is an accessory used to fix or extend the functionality of a vehicle's rearview mirror. It is mainly divided into two categories: original equipment manufacturer (OEM) rearview mirror brackets (used to support the rearview mirror itself) and functional extension brackets (such as action camera, mobile phone, or camera brackets). The automotive rearview mirror control panel bracket is made of plastic and is currently generally injection molded. The angled ejector mechanism is a component in the mold design used to handle the undercut (barbed) structure of the plastic part. It achieves demolding by pushing a slider with an angled surface. In automotive rearview mirror bracket molds, the angled ejector mechanism is mainly used to handle the undercut structure on the bracket, ensuring smooth demolding when the mold opens and closes.
[0003] After the existing automotive rearview mirror bracket mold is produced, the plastic part needs to be ejected. During ejection, the ejection direction is unidirectional and the range is small. When demolding, the plastic part is prone to jamming and collision with the mold, which affects the surface quality of the plastic part and the ejection accuracy is relatively average. Therefore, we propose an inclined ejection mechanism for the automotive rearview mirror bracket processing mold. Utility Model Content
