Silica sol wax mold forming device and forming method thereof

Abstract

The invention relates to a silica sol wax mold forming device and a forming method thereof. The silica sol wax mold forming device comprises a base, a sieve plate, a side baffle, an extrusion supporting plate, a push plate, a push spring and an extrusion mechanism, and further comprises a bottom plate, a clamping supporting plate, a fixing plate, a clamping mechanism, a forming support, a sandingmechanism and a recycling frame; and the clamping supporting plate is installed on the top of the left end of the bottom plate, a fixing plate is installed on the top of the clamping supporting platethrough a hinge, the clamping mechanism is connected to the left side face of the fixing plate, the forming support is installed on the top of the right end of the bottom plate, the sanding mechanismis installed at the upper end of the forming support, and the recycling frame is placed on the upper end face of the middle of the bottom plate. The problems that when existing manual sanding treatment is carried out on a wax mold, a certain rotating dead angle exists when the wax mold is manually rotated, so that the forming effect of the wax mold is poor, the continuity of manual rotating of thewax mold is poor, the sanding uniformity of the wax mold is low, and the hidden danger of falling exists when the wax mold is manually held can be solved.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a silica sol wax mold forming device and a forming method thereof. Background technique [0002] Silica sol wax casting is a method for casting parts with high precision requirements. This method needs to use wax to make a model, and weld the model to the sprue rod with the same material to make a module. Dip the mixture of silica sol and fine sand on the surface of the module, and then sprinkle fire-resistant sand. After that, dipping and sanding must be repeated several times to make the sand layer thick enough. After it is dry and solidified, heat the module, and the wax will It comes out from the gate to form a mold shell, and the metal liquid is poured in from the gate, and after condensation, it becomes a metal casting. [0003] At present, when sanding the silica sol wax pattern, the wax pattern dipped in the silica sol mixture is manually placed under the sand box, and ...

AI Technical Summary

Problems solved by technology

[0004] 1. When the wax mold is manually rotated, there will be a certain dead angle of rotation, which will result in poor molding effect of the wax mold, and the continuity of the manual rotation of the wax mold is poor, which makes the sanding uniformity of the wax mold low, and the wax mold is held manually. There is a danger of falling;

[0005] 2. The sand box can only sprinkle the fireproof sand vertically, so that the special structural position of the wax model cannot stick a certain amount of fireproof sand
