Technical Field

[0001] The invention relates to the technical field of lighting lampshade manufacturing, in particular to a lighting lampshade forming device. Background Art

[0002] A lampshade is a cover placed around the flame of a lamp or on a bulb to focus light or protect against wind and rain. The lampshade is not only placed on the lamp to gather light, but also to prevent electric shock and protect the eyes. Currently, the lampshade molding equipment for lighting lamps has the problem of being difficult to remove after molding.

[0003] To this end, a Chinese patent with publication number "CN211389789U" announced "a lighting lampshade molding device", whose main structure includes a table, an installation groove, a lower mold assembly, a sprue, a mold removal assembly, a support frame, a first hydraulic column, a brake block and an upper mold plate. When the lighting lampshade molding device is working, the first hydraulic column drives the brake block and the upper mold plate to move down into the installation groove, and the heated liquid plastic flows from the sprue into the space between the lower mold assembly and the upper mold plate for molding. After molding, the first hydraulic column drives the brake block and the upper mold plate to reset, and the lower mold assembly moves the lampshade out of the installation groove. The second hydraulic column drives the lower mold plate to move up and the lampshade moves up at the same time, which is convenient for removing the mold assembly and the lampshade.
