摘要:

分析了分体式空调器室内机底座的结构,设计了一套在定模与动模都设置了顶出机构的注塑模具。为了使定模方向的、又长又高的筋位脱模,并为了克服开模时形成的真空,设计了定模顶出机构;对于产品外侧的筋位与底壁,设计了由斜导柱驱动的滑块机构;对于底壁上的扣位,设计了由双斜面斜楔驱动的滑块机构;对于通风口上方的V形槽,以及下方的3个扣位,共用一个滑块机构脱模;对于产品右上角的小圆柱孔和左右两侧的出水管,由于倾斜角度较大,分别设计了不同结构的斜抽芯机构;对于位于通风口中间的筋位,设计斜顶结构;为了保证注塑质量,采用热流道进行浇注,并将浇口位置的侧壁设置成圆柱形。为了保证模温均匀,根据模具结构设计随形冷却水路。

Abstract:

This paper reports the structural analysis and injection mold design for a split⁃type air conditioner indoor unit base. A novel mold with ejector mechanisms integrated into both the stationary and moving halves was developed. To facilitate the release of long, high bars and counteract vacuum formation during mold opening, an ejector mechanism was specifically designed for the stationary mold. Various complex features on the part necessitated multiple specialized mechanisms: a slant⁃pin⁃driven slider was designed for the external rib and bottom wall features; a double⁃bevel⁃wedge⁃driven slider was implemented for the undercut on the bottom wall; and additional sliders were employed to demold the V⁃shaped groove above the vent and the three undercuts below it. For the small cylindrical hole in the upper right corner and the outlet pipes on both sides, which have high draft angles, differently structured angle⁃pin mechanisms were designed. An angled⁃lifter mechanism was utilized for the ribs within the vent. To ensure high⁃quality molding, a hot runner system with a cylindrical gate was adopted. Furthermore, a conformal cooling channel layout was designed to maintain uniform mold temperature.

Key words: split type air conditioner indoor unit base, plastic mold, hot runner, fixed mould push rod, release mechanism
