Continuous washing dewaxing device

Abstract

The invention discloses a continuous washing dewaxing device which comprises a washing room, a shell circulation mechanism and a dewaxing water circulation system, the shell circulation mechanism comprises a circulation track and a circulation power zipper, the circulation track penetrates through the washing room left and right, and a plurality of shell hanging assemblies are movably installed on the circulation track; the multiple shell hanging assemblies are connected through a circulation power zipper, the dewaxing water circulation system comprises a first water washing tank, a second cleaning water tank, a wax-water separation tower and a cleaning water source pool, and the first water washing tank and the second cleaning water tank are installed in the water washing room. Assembly line type cleaning and dewaxing operation can be achieved, the in-out continuity of a shell mold is good, the cleaning efficiency is greatly improved, meanwhile, the problem that heat energy loss of conventional equipment is large is solved, the water circulation system is designed, dewaxing water can be cyclically replaced in real time, the stability of the dewaxing effect is guaranteed, and the dewaxing quality is improved.

Description

technical field [0001] The invention relates to the technical field of precision casting production equipment, in particular to a continuous water wax dewaxing device. Background technique [0002] Precision casting refers to the general term for the process of obtaining precise size castings. Compared with the traditional sand casting process, the castings obtained by precision casting are more accurate in size and have a better surface finish. The most commonly used investment casting in precision casting is investment casting, also known as lost wax. Casting, this casting process is to first select a suitable investment material (such as paraffin) to make an investment, and then soak the investment into the shell liquid to form a shell mold, and then perform a dewaxing operation to remove the wax in the shell. The mold is removed, so that a hollow shell can be formed for subsequent pouring operations. Water dewaxing is a commonly used dewaxing method. The existing water d...

[0002] Precision casting refers to the general term for the process of obtaining precise size castings. Compared with the traditional sand casting process, the size of the castings obtained by precision casting is more accurate and the surface finish is better. The most commonly used in precision casting is investment casting, also known as lost wax. Casting, this casting process first selects suitable investment materials (such as paraffin) to make investment patterns, then soaks the investment pattern into the shell liquid to form a shell mold, and then performs dewaxing operation to remove the wax in the shell Remove the mold, so that a hollow shell can be formed for subsequent pouring operations. Water washing and wax removal is a commonly used dewaxing method at present. The existing water washing and wax removal equipment stacks many shell molds and places them on the In this mode of operation, the continuity of the dewaxing operation is poor, the number of shell molds for each dewaxing is limited, and the dewaxing efficiency is low. During operation, it is necessary to frequently open the tank cover of the cleaning tank, so that the heat loss is large, which does not meet the production needs of energy saving and emission reduction. Moreover, it is troublesome to change the water in the cleaning tank of traditional dewaxing and washing equipment. After long-term dewaxing operations, the cleaning tank The wax content in the cleaning water will be greatly increased, which is not conducive to the subsequent dewaxing and washing operations, and will affect the dewaxing effect
