The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1 to Fig. 3, the utility model injection mold 1 comprises that a dynamic model 10, is installed in ejecting mechanism 30 on the dynamic model 10 with the cover half 20 and of dynamic model 10 corresponding settings.

In the present embodiment, dynamic model 10 comprises that a dynamic mould fixing plate 11, a moving platen 12, an ejector retainner plate 13, a thimble fixed head 14, some thimbles 15 and are installed in the core 16 on the moving platen 12.Dynamic mould fixing plate 11 tops are provided with thimble fixed head 14, then be installed with ejector retainner plate 13 on the thimble fixed head 14, and above ejector retainner plate 13 moving platen 12 that is provided with separated by a distance, make the displacement between dynamic mould fixing plate 11 and moving platen 12 of ejector retainner plate 13 and thimble fixed head 14.Ejector retainner plate 13 is provided with an accepting groove 131, and thimble fixed head 14 is provided with a storage tank 141.Thimble 15 is fixed on the ejector retainner plate 13, and thimble 15 ends are equiped with one respectively and insert 17.

Please continue and consult Fig. 1 and Fig. 3, ejecting mechanism 30 comprises a movable angled slide block 31, a push rod 32, a limited post 33 and a reset post 34.Movable angled slide block 31 has a square matrix 311, these matrix 311 lower ends are provided with a face that compresses 312 that takes the form of inclined plane, lower end, matrix 311 left side is provided with a jacking block 313, movable angled slide block 31 is installed in the accepting groove 131 of ejector retainner plate 13 by a steady pin 40, this activity angled slide block 31 can be along steady pin 40 swings in accepting groove 131, push rod 32 1 ends pass moving platen 12 and core 16 and stretch out in core 16 ends, and push rod 32 other ends are resisted against jacking block 313 end faces.Limited post 33 1 ends are fixed on the moving platen 12, and reset post 34 is inserted in the storage tank 141 of thimble fixed head 14 versatilely.
