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, comprising a base, a sieve plate, a side baffle plate, an extrusion support plate, a push plate, a push spring and an extrusion mechanism, including a base plate, a clamping support plate, a fixed Plate, clamping mechanism, forming bracket, sand spreading mechanism and recovery frame, a clamping support 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 support plate through a hinge, and the clamping mechanism is connected to On the left side of the fixed plate, the forming support is installed on the right end top of the base plate, the upper end of the forming support is equipped with a sand spreading mechanism, and the recovery frame is placed on the middle upper end surface of the base plate. The present invention can solve the problem existing when sanding the wax mold manually: when the wax mold is manually rotated, there will be a certain dead angle of rotation, resulting in poor molding effect of the wax mold, and the continuity of the manual rotation of the wax mold is poor. Poor, so that the sanding uniformity of the wax model is low, and there are problems such as the hidden danger of falling when the wax model is manually held.

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
