the injection molding lampshade with the top opening comprises an upper cover shell and a lower cover shell which are connected with each other, wherein a first opening used for being connected with a heat dissipation rib plate is arranged at the top of the upper cover shell, a second opening used for being connected with a lamp holder is arranged at the bottom of the lower cover shell, and the upper cover shell and the lower cover shell are subjected to injection molding.

The technical scheme is further designed as follows: the lamp comprises an upper lamp shade, a lower lamp shade and a lamp body, wherein a first slot is formed in the bottom of the upper lamp shade, a second slot matched with the first slot is formed in the top of the lower lamp shade, and the upper lamp shade and the lower lamp shade are connected together through the matching of the first slot and the second slot.

The first slot and the second slot are in interference fit.

The middle part of the lampshade is provided with a plurality of vertically arranged convex ribs, and the convex ribs are formed by bending a shell of the lampshade outwards.

The joint of the upper and lower housings is positioned in the middle of the convex edge; the first slot and the second slot are bent outwards at the positions corresponding to the convex edges.

The top end of the upper lampshade is provided with a first hanging edge extending towards the inner side, the top surface of the first hanging edge is provided with an annular convex block extending upwards, and the convex block is used for being connected with the heat dissipation rib plate.

The lamp shade bottom is equipped with the second string limit that extends to the inboard down, be equipped with the connecting hole that is used for being connected with the lamp support on the second string limit.

The lampshade is spherical, lotus-shaped or magnolia-shaped.

The utility model has the advantages that:

the utility model discloses a lamp shade adopts injection molding process to make, can predetermine the opening at last housing top during the preparation, and it can form smooth opening to mould plastics, has avoided the later stage to cut the problem of the incision unevenness that causes, and the lamp shade of making of moulding plastics simultaneously compares the lamp shade that forms in prior art blowing, and each partial thickness is more even for the light that sees through the lamp shade is more even, and illumination and decorative effect are better.

The utility model discloses a lamp shade adopts the split type structure of upper and lower housing, provides the feasibility for the drawing of patterns of moulding plastics.
