The invention discloses a quantitative filling device for cosmetic production, and belongs to the field of cosmetic production equipment. The device comprises a conveying mechanism and a filling mechanism. The filling mechanism comprises a storage barrel body and a filling head communicating with the storage barrel body. The conveying mechanism comprises a fixed supporting table and a rotating table; a feeding notch, a filling station and a discharging notch are sequentially arranged on three sides of the fixed supporting platform, carrier plates are arranged on the rotating table at equal intervals, lifting rods are fixed at the bottoms of the carrier plates, and the lifting rods are connected with a rotating lifting driving mechanism; and the filling head is aligned with the eccentric position of a bottle mouth of a filling bottle below the filling head; a limiting rod is arranged in the storage barrel body, a screw rod penetrating through the storage barrel body is fixed on the limiting rod, an adjusting port is formed in the position, through which the screw rod penetrates, of the storage barrel body, and the screw rod is sleeved with a locking nut. Insufficient filling quantity caused by foam accumulation in the filling bottle can be avoided, and the reliability of the filling process is guaranteed; the primary filling amount of the filling mechanism is adjustable, so thatquantitative filling can be realized; and automatic feeding, filling and discharging can also be realized.

The invention provides a die casting mold with a connecting rod body cavity liquid inlet multi-flow channel structure. The die casting mold with the connecting rod body cavity liquid inlet multi-flowchannel structure comprises a fixed mold core and a movable mold core; the fixed mold core and the movable mold core surround to form a melt flow channel and multiple connecting rod body cavities inside; the melt flow channel comprises a primary main flow channel and multiple secondary main flow channels; each two of the multiple secondary main flow channels are symmetrically arranged on the two sides of the primary main flow channel; the primary main flow channel and the multiple secondary main flow channels are correspondingly distributed in the vertical direction and the transverse direction; the multiple connecting rod body cavities are correspondingly arranged on one sides of the multiple secondary main flow channels in a one-to-one corresponding manner; the extending directions of the connecting rod body cavities and the secondary main flow channels are as same as each other; multiple sub pouring flow channels are arranged between a rod body molding cavity of each connecting rodbody cavity and the secondary main flow channels; during die casting of the connecting rods, an aluminium alloy melt enters the connecting rod body cavities via multiple sub pouring flow channels; andtherefore, the melt filling speeds of the connecting rod body cavities are effectively increased. According to the die casting mold with the connecting rod body cavity liquid inlet multi-flow channelstructure, multiple aluminium alloy connecting rods can be simultaneously produced through die casting, it can be guaranteed that the melt is full of the connecting rod body cavities, and the qualification rate of connecting rod finished products can be increased.
