slide to the inside，Inner core pulling slide block is made to deviate from the inner card cage 18 of automobile lamp 17，Now the oblique surface 45 of lead 44 contacts with the oblique sliding surface of twice-die-opening jacking block，Twice-die-opening jacking block 42 slid inward is driven by lead 44，Twice-die-opening push rod 41 is made to disengage twice-die-opening jacking block，Such core 15 and core insert 16 are moved rearwards by under the induced effect of core plate 14，Make thimble 12 will complete automobile lamp 17 ejection device loosed core.The inner card cage mould emptier of this programme automobile lamp injection mold, core plate 14 is adopted to synchronize to drive check lock lever 19 and guide post 20, guide post drives guide runner 24 and inner core pulling slide block 23 to carry out inner core pulling, simple in construction, reliable in action, it is convenient in demoulding, and owing to the structural strength between inner core pulling slide block 23 and connecting rod 31 is poor, easily rupture in junction, the upper oblique locking face 26 of interior core-pulling slide block 23 is contacted by the declivity locking face 21 having had check lock lever 19, play reliable lock on the one hand, when preventing injection sizing material, injection pressure is excessive, cause that inner core pulling slide block produces mobile, play the structural strength strengthening inner core pulling slide block 23 with connecting rod 31 on the other hand, ensure its service life.Arranging wear-resistant pad 28 in described core insert 16, wear-resistant pad contacts with inner core pulling slide block 23 and guide runner 24.There is wear-resistant pad 28, reduced the abrasion with inner core pulling slide block 23 and guide runner 24, increase service life.Having locking slot 29 in described die cavity 6, locking slot matches with the head of Angle Pin 22.After matched moulds, Angle Pin 22 head is locked by locking slot 29, it is to avoid Angle Pin produces mobile, reliable lock.
