Abstract

The invention discloses die-casting equipment for semi-solid castings, and relates to the technical field of stamping injection molding. The die-casting equipment comprises a die-casting table; a coordination fixed plate is fixed to one end of the top end of the die-casting table, a first hydraulic piston cylinder is fixed to one end of the coordination fixed plate through screws, a discharging push plate is fixed to the output end of the first hydraulic piston cylinder, and a conveying discharging roller wheel is installed at the other end of the top end of the die-casting table. According tothe die-casting equipment for the semi-solid castings, through the design of a stress sharing hedging forming structure, in the die closing process of the device, the manufacturing accuracy of a model bottom die is improved in a bidirectional hedging die-casting mode, rigid springback is avoided through elastic force relief at the bottom die supporting position, pressure is prevented from being directly conducted to the supporting position of the bottom die, the service life is prolonged, through the design of the self-lubricating top die structure, the device can automatically oil a telescopic rod and the interior of a die cavity in the punching reciprocating process, the complex process of manual oiling is avoided, and the use convenience of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of stamping and injection molding, in particular to a die-casting equipment for semi-solid castings. Background technique [0002] Die casting is a metal casting process, which is characterized by applying high pressure to the molten metal in the cavity of the mold. It is a manufacturing method for parts processing. During the preparation process of die casting, lubricants need to be sprayed into the cavity. In addition to helping to control the temperature of the mold, it can also help the demoulding of the casting. However, the existing devices often require manpower to lubricate the mold cavity and the piston push rod, resulting in an increase in the complexity of the use, and the bottom The film is often directly impacted, and the supporting part and the model itself are under a large force, and cannot be moved against the hedge, resulting in poor manufacturing accuracy of the molding at the bottom film....
