Glass Lamp cup mould air cooling punch structure
Technical field
The utility model relates to Glass lamp cup formation mould, is specifically related to a kind of glass Lamp cup mould air cooling punch structure.
Background technology
Glass Lamp cup mold and punching head is a Glass lamp cup formation mould most important parts, and its structure design directly influences the serviceability and the work-ing life of mould.Present glass Lamp cup mold and punching head is mainly formed by Lamp cup reflection shield moulding drift with through the Lamp cup cup moulding drift that is threaded in this drift front end.Because this punch structure design reckons without drift cooling problem in the course of the work, in the process of non-stop run, mould is subject to high temperature action and deforms, and influences the work-ing life of glass Lamp cup quality product and mould.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of and can effectively improve the quality of products and the glass Lamp cup mould air cooling punch structure of die life.
The technical scheme that realizes above-mentioned purpose is: a kind of glass Lamp cup mould air cooling punch structure, it includes Lamp cup reflection shield moulding drift, be assemblied in the central through hole of Lamp cup reflection shield moulding drift and and be fixedly connected with a drift core with Lamp cup reflection shield moulding drift, the bottom of this drift core protrudes from the lower surface of Lamp cup reflection shield moulding drift and constitutes Lamp cup cup moulding drift part, upper end at the drift core fixedly is equipped with terminal pad, upper end at terminal pad fixedly is equipped with Connection Block, concentric is arranged at Connection Block, one air-cooled centre hole is arranged on terminal pad and the drift core, wear ring through being assemblied in the Connection Block upper end is suspended to a drift core forced air cooled tube in the air-cooled centre hole, the inner chamber of this drift core forced air cooled tube constitutes cooling air and enters the effusive air intake passage from the lower end by the upper end, constitute drift core air cooling and the air exhaust passage of cooling air between the outer tube wall of drift core forced air cooled tube and the hole wall of air-cooled centre hole by the lower end of the drift core forced air cooled tube radially air outlet opening to the Connection Block, terminal pad is provided with the radially intake opening that is connected with annular air-cooled chamber, terminal pad middle part, be connected with the air-cooled chamber of annular and stretch in the vertical wind cooling hole in the Lamp cup reflection shield moulding drift Lamp cup reflection shield moulding drift forced air cooled tube is arranged, the air cooling chamber that forms between the hole wall of the vertical wind cooling hole in the outer tube wall of this Lamp cup reflection shield moulding drift forced air cooled tube and the Lamp cup reflection shield moulding drift is connected with the radially air outlet opening on the Connection Block, constitutes the air cooling and the air exhaust passage of Lamp cup reflection shield moulding drift.
Above-mentioned drift core forced air cooled tube is joined by the body of two sections upper coarse and lower fine different tube diameters and forms.
Above-mentioned Lamp cup reflection shield moulding drift forced air cooled tube has three at least along the circumference uniform distribution of Lamp cup reflection shield moulding drift.
Radially air outlet opening on the above-mentioned Connection Block is provided with a plurality of.
The utility model is compared with existing glass Lamp cup mold and punching head, has following advantage:
1, can significantly reduce the working temperature of drift, avoid the mould temperature distortion.
2, the stability of Lamp cup reflection shield moulding drift and Lamp cup cup moulding drift fit structure is good, the intensity height of withstand shock, and make things convenient for the maintenance of mold and punching head.
3, can effectively improve the work-ing life of glass Lamp cup quality product and glass Lamp cup mould.
