一、概述 压制图1所示带有嵌件的塑料工件时,为了提高塑件的外表质量,塑件必须由顶杆推动嵌件出模。为此,必须设计顶杆顶出塑件后自动复位的机构。我们采用了活动板顶杆式自动复位顶出机构(如图2所示)。该机构能在开模顶出工件的同时实现顶杆2的自动复位,开模后即可安放嵌件,在一次启动机床闭合模具情况下,就能压制出完整的塑件。 First, an overview Suppression Figure 1 shows the plastic parts with inserts, in order to improve the appearance of plastic parts, plastic parts must push the push rod ejector die. To this end, must be designed ejector push the plastic automatically reset after the body. We use the movable plate ejector rod automatic reset ejection mechanism (shown in Figure 2). The mechanism can eject the workpiece at the same time realize the automatic resetting of the ejector rod 2, and the insert can be placed after the mold is opened, so that the complete plastic part can be pressed under the condition of starting the mold closing tool.
