Background

The car seat support is installed on car seat skeleton for support a structure of car seat, the shaping that has car seat support generally adopts the mode of die-casting.

Die casting is a metal casting mode, and the basic technological process of die casting is as follows: molten metal is cast at low speed or high speed and filled into the cavity of the mold, the mold has movable cavity surface, and it is pressurized and forged along with the cooling process of the molten metal, so that the shrinkage cavity and shrinkage porosity defects of the blank are eliminated, and the internal structure of the blank reaches the broken crystal grains in the forged state. The comprehensive mechanical property of the blank is obviously improved, a die-casting die is required in a die-casting process, the die-casting die is generally divided into an upper die and a lower die, the upper die is generally a core of a male die, the lower die is generally a cavity of a female die, the core of the upper die is attached to the cavity of the lower die when the die-casting die is used, then liquid metal is injected into the cavity at high pressure, the high pressure is maintained until the metal is cooled and formed, and then the die-casting process of the metal piece is completed after the.

The leakproofness between the upper die and the lower die of the existing die casting die is not very good, the problem of metal liquid leakage can occur in the die casting process, the die assembly line is obvious, the time of later-stage cutting and polishing is wasted, and if the existing die casting die does not have a good demolding inclination during demolding, the support is difficult to eject by a push rod, and the condition that the push rod pushes away too much and causes adhesion of workpieces and material shortage easily occurs.

The sprue gate of current die casting die is great because the molten metal velocity of flow that high pressure jetted into, and the die cavity of impact mould leads to local die cavity temperature to rise fast, leads to the formation of mucosa, and then the phenomenon of mucosa appears when the drawing of patterns, and the taking out of very inconvenient work piece, the impact of molten metal can cause the damage to the mould moreover, has reduced the life of mould.
