轴承橡胶密封圈在我国的工业生产中,需求量日益增多,占有十分重要的地位。单件生产很不经济。我们设计的如图1所示压模,是在25吨面积为300×400毫米~2的橡胶压模机上使用的。它有12个型腔,每个型腔有一对上、下成型模芯,一次可成形12个零件。这种压模的优点是,模具的加工精度低,效率高,操作方便。 Bearing rubber seals in China’s industrial production, the increasing demand, occupy a very important position. One-piece production is not economical. The die we designed, as shown in Figure 1, is used on a 25 tonne rubber press with an area of ​​300 × 400 mm2. It has 12 cavities, each cavity has a pair of upper and lower mold core, a shape of 12 parts. The advantage of this stamper is that the mold has low machining accuracy, high efficiency and easy operation.
