PCT No. PCT/SE82/00083 Sec. 371 Date Dec. 13, 1982 Sec. 102(e) Date Dec. 13, 1982 PCT Filed Mar. 23, 1982 PCT Pub. No. WO82/03594 PCT Pub. Date Oct. 28, 1982.A method and a mold for the manufacture of a wheel construction (2) of plastic material for vehicles or the like, which comprises a number of spokes (2A-2H), a hub (2J) and a rim (2I) together constituting an integrated unit. The plastic material is injected in a mold (1), the cavity (7) of which exhibits a form corresponding to the one of the desired wheel construction, the design of the wheel being chosen to comprise an even number of spokes (2A-2H). The inlets (3-6) are located at such points near to every second one of the spoke portions (2A-2H) forming part of said mold (1), that the zones (7'), where the flows of material join each other, will be located near to points, where the spoke portions (2B, 2D, 2F, 2H), free from inlets, blend into the rim (2I). |
