Rotary type hanging tool

Abstract

The invention discloses a rotary type hanging tool. The rotary type hanging tool comprises bases, hooks, friction wheels, upper covers, mandrels, bearings and bearing seats; each base is a rectangularplate block; and the bottom side of each base is at least provided with two rectangular grooves, wherein the opening of each rectangular groove is downward. The two sides of a gap which is pre-formedin the bottom side of each hook are provided with a pair of open inner hooks which are equal in length; and each rotating shaft structure consisting of the corresponding upper cover, the corresponding mandrel, the corresponding bearing and the corresponding bearing seat is arranged at the center position of the upper side of the corresponding hook. A groove pre-formed in the upper end face of each upper cover is combined with the corresponding base in an embedding manner and is connected with the corresponding base through a bolt so as to form the corresponding hook which is hung in the gap of the corresponding base and rotates with the corresponding mandrel. Each mandrel is connected with the corresponding friction wheel; each friction wheel has friction with an external triangular beltin a running process to obtain kinetic energy so as to rotate with the corresponding mandrel, and thus a work piece mold shell hung on the corresponding hook can rotate synchronously. Therefore, by adopting the rotary type hanging tool, the drying quality and the drying efficiency of the work piece mold shell can be greatly improved.

Description

technical field [0001] The invention relates to an appliance for precision casting shell making, in particular to a hanger for hanging mold shells, especially a rotary hanger. Background technique [0002] The shell-making process is a key process in the precision casting process, and its manufacturing quality determines the quality of the casting. The shell-making process in the investment casting process is actually the process of alternately hanging slurry and drying on the investment pattern, and the drying speed directly determines the shell-making production efficiency. In actual production, the mold shell is usually hung to dry after the mold is removed. In order to further increase the drying speed, the industry increases the temperature and wind speed in the drying room as much as possible under the permitted conditions. This technical measure is effective and can achieve the effect of accelerating the drying of the mold shell. However, the formwork made by the pr...

Problems solved by technology

However, the formwork made by the prior art is in a relatively static state during the drying process, and the formwork is affected by the wind direction and temperature field in the drying chamber, which may easily cause differences in the drying degree of parts with different orientations.

The drying degree of each part of the formwork is uneven, which will inevitably affect the quality of the slurry in the later stage. Therefore, the existing technology still cannot meet the needs of rapid and efficient drying in mass production, so further improvement is needed.
