A wheel hub die-casting mold

Abstract

The invention discloses a hub die-casting mould. The hub die-casting mould comprises a lower die, a side die and an upper die which are combined to form a hub casting cavity; the lower die is arranged on a lower template, and the side die is formed by glidingly connecting four sections to an arc part of the lower template; four arc parts are respectively located at two groups at left and right sides of the lower die; an included angle at 3-10 degrees is arranged between the gliding traces of two arc parts of every group and diameters in left and right directions of the lower die. The hub die-casting mould further comprises two connecting blocks respectively arranged at outsides of two groups of arc parts, wherein connecting holes are arranged on the connecting blocks, the outer walls of the two arc parts of every group are respectively provided with pulling hooks, and the pulling hooks are glidingly connected to the connecting holes. Through two connecting blocks, two section arc parts of one group are respectively pulled; two connecting blocks are not required to drive by two oil cylinders, thus the oil cylinder energy consumption in the pouring process is reduced by a half, and the manufacturing cost of the hub is greatly reduced; the cavity pressure is provided through a lock die sleeve; the hub die-casting mould overcomes the limit of the oil cylinder specification, and further reduces the manufacturing cost of the hub.

Description

technical field [0001] The invention relates to the field of wheel hub casting, in particular to a wheel hub die-casting mold. Background technique [0002] The wheel hub is the part of the vehicle used to connect the tire and the shaft. From the manufacturing process, it can be divided into three types: integral casting type, integral forging type and composite type. Among them, the integral casting type wheel hub occupies the total output of the wheel hub due to its low cost. About 90%. The manufacturing process of the integral cast wheel hub is to pour aluminum water, that is, liquid aluminum alloy, into the cavity of the mold. After the aluminum water solidifies to form a wheel hub blank, it is demoulded and cooled, and then deburred, polished, and surface treated to obtain the finished wheel hub. ;According to the different pouring process of aluminum water, it is divided into gravity casting and pressure casting; the structure of the wheel hub is a cylindrical shape c...
