机体盖是电子打火机的主要零件,用30克卧式注射机注射工程塑料 ABS 成形。产品零件如图所示,机体盖形状虽然不太复杂但尺寸较小。这对塑料模具的设计与制造带来困难,下面简述模具的结构特点。(1)经计算,一模可以注射两件。为了确保制件的质量,故采用侧浇口的两板式结构形式。这样比点浇口三板式的结构 Body cover is the main part of the electronic lighter, with 30 grams of horizontal injection molding machine injection molding engineering ABS plastic. Product Parts As shown, the shape of the body cover, though less complicated, is smaller in size. This plastic mold design and manufacture of the difficulties, the following brief description of the structural characteristics of the mold. (1) After calculation, a mold can be injected two. In order to ensure the quality of parts, so the use of side gate of the two plate structure. This is more than the point gate three-plate structure
