Description

Technical Field

[0001] The invention relates to the field of die-casting of reducer housings, and in particular to a die-casting device for reducer housings which can be quickly positioned. Background Art

[0002] The die casting of reducer housing is a common metal forming process used to manufacture the housing or shell of the reducer. The reducer housing die casting equipment with quick positioning is a die casting machine specially designed for the efficient production of reducer housings. It is characterized by the ability to quickly change molds, significantly shorten production preparation time and improve production flexibility.

[0003] The existing reducer housing die-casting equipment that can be quickly positioned adopts quick fixing methods such as plug-in or snap-on between the mold and the die-casting machine, aiming to shorten the time of mold replacement. The design of this connection structure allows the mold to be quickly installed and disassembled, thereby realizing rapid mold change. However, due to the heavy weight of the mold itself, it is impossible to handle it directly by hand, so it is necessary to use lifting equipment to assist the loading and unloading process of the mold. During the use of the lifting equipment, if the mold is not kept precisely in a horizontal state, it is difficult to align and fix it with the connection structure on the die-casting equipment. It is very difficult to manually adjust the mold to a completely horizontal state and difficult to position quickly, especially when the mold has a certain tilt angle, positioning is even more difficult, which directly affects the speed and efficiency of mold replacement.
