Method for producing rim for motor vehicle wheel from aluminum or aluminum alloy, and corresponding device for producing rim

The invention relates to a method for producing a rim (2) for a motor vehicle wheel from aluminum or an aluminum alloy, the rim (2) having a rim seat (3) delimited on opposite sides by an outer edge (7) and an inner edge (8), a hub (5) having a central recess and a bore ring, and a rim center (4) connecting the rim seat (3) and the hub (5) to each other. According to the invention, the rim (2) is produced in a one-piece and continuous manner in the casting mould by die-casting the casting material, the volume of the casting mould (9) being reduced after the casting material is introduced into the casting mould (9) in order to post-compress the casting material. The invention further relates to a device (1) for producing a vehicle rim (2). 本发明涉及一种用于由铝或铝合金制造用于机动车车轮的车轮辋(2)的方法，其中，车轮辋(2)具有在相对两侧由外缘部(7)和内缘部(8)界定的轮辋座(3)、具有中央缺口和孔圈的毂部(5)以及使轮辋座(3)与毂部(5)彼此连接的轮辋中部(4)。在此规定，通过对铸造材料的压铸一件式且连续地在铸模中制造车轮辋(2)，其中，在将铸造材料引入铸模(9)中之后缩小铸模(9)的体积以对铸造材料进行后压缩。此外，本发明涉及一种用于制造车轮辋(2)的设备(1)。
