Motor shell mold head for deep water pump

Abstract

The invention discloses a motor shell mold head for a deep water pump. The motor shell mold head for the deep water pump comprises a body, a motor shell wax piece, a mold head, gates, a rear runner, a first side runner, a second side runner and a front runner, wherein a mold head is arranged on the body; a plurality of gates are arranged on the motor shell wax piece, and the gates and the motor shell wax piece are integrally formed through a wax mold; the rear runner is arranged at the rear end of the mold head, and the mold head is connected with the rear runner through a wax adhering mode; the front runner is arranged at the front end of the mold head, and the mold head is connected with the front runner through a wax adhering mode. Through improvement, the motor shell mold head for the deep water pump has the advantages that the structure design is reasonable, enough filling and feeding capability is guaranteed, a reasonable solidification sequence is formed, sand hanging is not broken so as to facilitate the shell-making operation, so that the problems and the defects in an existing device are effectively solved.

Description

technical field [0001] The invention relates to the technical field of investment casting, in particular to a motor shell die head for a deep water pump. Background technique [0002] The gating system is a very important work in the investment casting process design, and the gating system is closely related to the casting quality, production efficiency and cost. [0003] The motor casing die head for deep water pumps is formed by investment casting, but the wall thickness of the casing is relatively thin, and it often occurs that the filling is not enough during the casting process, that is, the filling is poor. The reason is mainly due to the casting process of thin-walled parts. The turbulent flow of molten metal in the medium causes heat loss and rapid solidification, which in turn leads to poor circulation of molten metal. [0004] In view of this, the existing problems are studied and improved, and a motor casing die head for deep water pumps is provided, which can en...

[0003] The motor casing die head for deep water pumps is formed by investment casting, but the wall thickness of the casing is relatively thin, and it often occurs that the filling is not enough during the casting process, that is, the filling is poor. The reason is mainly due to the casting process of thin-walled parts. The turbulent flow of molten metal in the middle causes heat loss and rapid solidification, which leads to poor circulation of molten metal
