某一电热壶的把手系胶木零件,如图1所示。零件用普通型热固性酚醛塑料粉挤塑成形,现将该模具介绍如下。一、模具的基本结构图2中,上工作台1与立式单缸油压机的工作油缸连接,作下压移动,并固定装配着电热板2。料筒3靠上盖板21限位,上盖板与上模套用螺栓紧固。带有台阶的上型腔板20装配在件19内。上述这些为上模,即动模部分。在下模(定模)部分,下型腔板15带有台阶,同样装配在下模套14内,并与下电热板13、模架10分别用螺栓紧固成一体。件16与17是抽芯凸模Ⅰ和Ⅱ,分别在开有T型槽的下模套内滑动,底部有一限位销。转顶臂7与提拉臂5组成开模装置,联合动作将动模部
The handle of a certain electric kettle bakelite parts, shown in Figure 1. Parts with ordinary thermosetting phenolic plastic powder extrusion molding, the mold is introduced below. First, the basic structure of the mold In Figure 2, the upper table 1 and the vertical cylinder hydraulic cylinder hydraulic cylinder connection, for the pressure to move, and fixed assembly of the hot plate 2. The cylinder 3 is limited by the upper cover plate 21, and the upper cover plate and the upper die sleeve are bolted. The stepped upper cavity plate 20 fits within the piece 19. These are the upper mold, that is, moving part. In the lower die (fixed mold) part, the lower cavity plate 15 with a step, also fitted in the lower die sleeve 14, and the lower hot plate 13, the mold frame 10 are bolted integrally. Pieces 16 and 17 are core-pulling pallets I and II, respectively sliding in the lower die case with the opening of the T-slot and having a limit pin at the bottom. Rotating top arm 7 and the lifting arm 5 constitute a mold opening device, the joint action will move the Department
