Novel die casting mould

Abstract

The invention discloses a novel die casting mould. The novel die casting mould comprises a mould fixing frame. A pressure chamber cavity is formed in the mould fixing frame. A pushing block is arranged in the pressure chamber cavity. The pushing block is connected with a fine tuning motor arranged at the exterior of the mould fixing frame through a fine tuning mechanism. A gas exhausting groove isconnected with the pressure chamber cavity and is connected with a connecting pipe. The connecting pipe is provided with a vertical pipe. The other end of the vertical pipe communicates with one endof a horizontal pipe. A collecting box is arranged between the vertical pipe and the horizontal pipe. The vertical pipe and the horizontal pipe are in threaded connection with the collecting box. Theother end of the horizontal pipe communicates with one end of a gas inlet pipe. The other end of the gas inlet pipe is connected with a water storage tank. A one-way valve is arranged on the gas inletpipe. The horizontal pipe is externally provided with a heat exchange pipe. The heat exchange pipe is connected with the horizontal pipe in a sleeving mode. The novel die casting mould is simple in structure, convenient and practical, the actual size of the pressure chamber cavity can be accurately adjusted, high-temperature high-pressure gas or molten metal can be directly discharged out of themould through the gas exhaust groove, scald of workers is avoided, and the novel die casting mould is safer.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a novel die-casting mold. Background technique [0002] Die-casting mold is a method of casting liquid forging, and die-casting is a process completed on a die-casting forging machine. During die-casting, the metal liquid is first filled into the die-casting mold cavity (pressure chamber cavity) on the die-casting die forging machine, and is forged under pressure during the cooling process of the metal liquid, so that the mechanical properties of the metal blank are improved, and the die-casting parts are obtained. product. [0003] The cavity of the die-casting mold is a channel for the gas in the cavity to be squeezed out and discharged from the high-temperature and high-pressure environment during the process of filling the cavity with molten metal at high temperature and high pressure. Its main function is to discharge the high-temperature and high-pressure gas in ...

Problems solved by technology

[0003] The cavity of the die-casting mold is a channel for the gas in the cavity to be squeezed out and discharged from the high-temperature and high-pressure environment during the process of filling the cavity with molten metal at high temperature and high pressure. Its main function is to discharge the high-temperature and high-pressure gas in the cavity , to prevent the generation of air bubbles on the castings and affect the quality of the castings. In the project where the high-temperature and high-pressure gas is discharged from the exhaust groove, sometimes molten metal and gas are discharged from the exhaust groove at the same time. The high-temperature and high-pressure gas or melting The metal is directly discharged to the outside of the mold through the exhaust groove, which may easily cause burns to workers. Now there is an urgent need for a die-casting mold that can prevent workers from being burned.
