Lesson 12 Typical Two-plate Injection MoldFigure 13-1 shows an exploded view of the elements of a typical two-plate injection mold. (两板式注塑模) (单分型面注塑模)(Single parting plane injection mold;Single joint plane injection mold)A brief description of each element follows:1. Locating ring ----aligns the nozzle of the injection-molding (定位环) (喷嘴) machine with the mold 2. Sprue bushing ----a conical channel that carries the injected (浇口套) plastic through the top clamp plate (定模座) to the part or runner system.3. Clamp plate ----secures the stationary side of the mold to the molding machine. Clamps are inserted in the recess between the clamp plate and cavity-retainer plate.(型腔固定板)4. Cavity retainer plate ---holds the cavity inserts (the cavity (型腔嵌件) is the area where the part is formed).5. Leader pin ----provides alignment for the two halves of the (导柱) mold as it opens and closes.6. Leader pin bushing-----provides close tolerance guide (导套) for leader pin.7. Core retainer plate ----holds the core element, the mating (型芯固定板) half of the cavity.8. Support plate ----adds rigidity and strength to the plate (支撑板) stackup (not used in all molds ).9. space block ----provides travel space for the ejector plate (垫块) and ejector pins. (推板) (推杆)10. moving plate ----secures the moving side of the mold to the (动模座) injection molding machine. (注塑机) It is mounted in the machine by screws or press plate as stationary plate. (压板) (定模座) 11. Ejector plate ----is often referred to as the ejector cover plate. provides backup for pins set into the ejector-retaining plate.(推杆固定板)12. Ejector retainer plate -----plate in which the ejector pins are held.13. Ejector pin -----pushes part off the core or out of the cavity.14. Return pin ----- returns the ejector plate back to its original (复位杆) position when the mold is closed15. Sprue puller pin -----pulls sprue out of the bushing when (拉料杆) mold opens by means of an undercut 16. support pillar----gives strength and rigidity for the ejector (推板导柱) plates to eject parts smoothly. 17. ejecting guide bushing----provides close tolerance guide (推板导套) for ejecting guide pin. 18. supporting pin----adjusts ejecting length of travel for the (支撑钉) ejector mechanism.Core -----the male part of the cavity.Cavity-----place where the plastic is formed. Some molds may have the cavity cut directly in the cavity plate rather than by the use of an insert as shown.Gate------the restricted area of the runner right before the material enters the cavity.Runner ----a passageway for the plastic to flow from sprue to the part.Sprue----a passageway for the plastic from the nozzle to the runner.
