The invention relates to the technical field of mold forming, and discloses an automobile thin-wall door plate and an injection mold thereof, a front mold plate of the injection mold is provided with a front forming area, a rear mold plate is provided with a rear forming area, and a forming cavity is formed between the front forming area and the rear forming area; five large-flow glue injection ports are formed in the front mold plate; a loudspeaker mesh insert is also arranged on the rear mold plate; the horn mesh insert comprises an insert body and a gas dispersing steel insert, and the gas dispersing steel insert is arranged close to the edge of the rear forming area; the rear mold plate is further provided with a plurality of ejector pins and a plurality of first straight ejector blocks, the ejector pins are arranged on the loudspeaker mesh insert in a penetrating mode, and the first straight ejector blocks are sequentially arranged at intervals along the outer side of the edge of the rear forming area. According to the injection mold, the problems of top penetration and top whitening caused by the holding force of a horn mesh and a reverse buckle on the automobile thin-wall door panel on the rear mold plate can be avoided.
Description
technical field [0001] The invention relates to the technical field of mold forming, in particular to an automobile thin-walled door panel and an injection mold thereof. Background technique [0002] Existing automobile door panel (see accompanying drawing description figure 1 ) is composed of the upper body, map bag and speaker net connected. Most of the current car door panels are divided into three parts for injection molding, that is, the body, map bag and speaker net are divided into three parts for injection molding, and the molded parts are assembled with connecting parts. Such a structure increases the subsequent assembly process, and the overall production efficiency is low. Due to the increasing requirements of the automotive industry for lightweight vehicles, most of the current automotive components need to be made into thin-walled products. Such as figure 1 The thin-walled door panel of the car shown in , its wall thickness is only 2.0mm, a large through hole...
