Description

Technical Field

[0001] This utility model relates to the field of lost-wax casting technology, and in particular to an auxiliary tooling for suspending wax molds. Background Technology

[0002] The lost-wax casting method, also known as the investment casting method, is a precision casting method for bronze and other metal objects. A wax mold is made, and a modeling material is applied to it to form a complete mold. The mold is heated to melt away the wax, forming a hollow cavity. Liquid metal is then poured into the cavity, and after cooling, the final casting is obtained. Current bronze casting technology involves multiple processes, including sculpting, making a silicone mold, pouring wax, applying a slurry, dewaxing, firing, casting, finishing and polishing, and coloring.

[0003] The wax model needs to undergo multiple dipping and drying processes during the slurry application to ensure the thickness of the entire outer shell. However, it is common practice to hang the wax model vertically after dipping, and under the influence of gravity, the slurry will accumulate at the bottom, resulting in a thick slurry at the bottom and a thin slurry at the top. Therefore, a hanging auxiliary fixture is needed to solve the problem of uneven slurry thickness on the outer surface of the wax model. Utility Model Content

The rotating mechanism includes a rotating block, a pry bar, and a positioning plate. The rotating block is mounted vertically at the end of the rotary shaft, and a pry bar is hinged to the rotating block perpendicular to the axis of the fixed shaft. The pry bar can swing around the hinge point in the vertical plane, driving the rotating block to rotate, thereby causing the crossbeam to rotate. The positioning plate is mounted on the outer surface of the column. The positioning plate has an arc-shaped structure, and its inner wall is provided with several slots for engaging with the end of the pry bar to limit the rotation of the rotating block. The slurry collection tank has several units and is set below each crossbeam. The two ends of the slurry collection tank are provided with plug-in units that cooperate with the C-shaped buckles on the inner wall of the column to realize the installation of the slurry collection tank on the column, which is used to collect the slurry dripping from the wax model after slurrying and hanging on the crossbeam.

[0006] Furthermore, a hinge groove is provided on the rotating block in a direction perpendicular to the axis of rotation, and hinge holes are provided on the inner walls of both sides of the hinge groove; a pin is provided on the side wall of the pry bar to cooperate with the hinge holes, so as to realize the hinge of the pry bar on the rotating block, and the end of the pry bar extends out of the rotating block for cooperating with the slot on the positioning plate.

[0009] The advantages of this utility model are: 1) In this utility model, a crossbeam driven by a rotating mechanism is set on the column of the wax model hanger. Multiple wax models after sizing can be hung on the crossbeam by hooks.
