The mold for manufacturing a bulb lamp according to claim 4, wherein: jacking subassembly (337) are including bearing block (3371), pole setting (3372), support frame (3373), ejecting pole (3374) and spacing ring (3375), bearing block (3371) run through branch (335) inboard and rather than sliding fit from top to bottom, the bearing block (3371) top left and right sides is fixed with pole setting (3372), pole setting (3372) run through baffle (336) inboard and rather than support frame (3373) fixed mutually, support frame (3373) top is fixed with ejecting pole (3374), ejecting pole (3374) insert the inside bottom side of shaping groove (35) and rather than sliding fit from top to bottom, ejecting pole (3374) middle part is run through in spacing ring (3375) inboard and rather than sliding fit from top to bottom.
9. The mold for manufacturing a bulb lamp according to claim 8, wherein: the number of the ejection rods (3374) is eight, the eight ejection rods (3374) are respectively inserted into the inner sides of the forming grooves (35), and the ejection rods (3374) are in seamless fit with the forming grooves (35).
10. The method for rapidly demoulding the mould for manufacturing the bulb lamp according to any one of the preceding claims, wherein the method for rapidly demoulding comprises the following steps:
s1, extruding a pressure lever (3312) by the upper die holder (8) during molding, wherein the pressure lever (3312) drives a lower pressure block (3314) to push a lower rod body (3321) to the right side through an upper pressure block (3313);
s2, the lower rod body (3321) drives the sliding block (3341) to move to the left under the action of the gear (3323), and the sliding block (3341) enables the bearing block (3371) to drive the support frame (3373) to move downwards in the limiting ring (3375) through the push rod (3343);
s3, the supporting frame (3373) drives the ejector rod (3374) to move downwards to be flush with the bottom side of the inside of the forming groove (35);
and S4, after the product is molded, the upper die holder (8) is separated from the pressure lever (3312), and the lower pressure block (3314) is reset under the action of the elastic force of the spring (3315), so that the ejection rod (3374) rises in the molding groove (35) to eject the product from the molding groove (35), and rapid demolding is realized.
