Engine sand core infiltration tool

Abstract

The invention provides an engine sand core infiltration tool. The tool comprises a placement box, wherein tracks are arranged on the inner wall of the placement box, isolation devices are arranged inthe placement box, the isolation devices comprise matrixes, isolation blocks are arranged on the matrixes, clamping blocks are arranged on the two sides of each matrix, the clamping blocks are clamped in the tracks so as to clamp the isolation devices inside the placement box, and the isolation blocks are distributed on the upper end surface and the lower end surface of each matrix. According tothe tool, a product is placed through the placement box, parts are fixed through the isolation blocks on the matrixes, so that the parts can be regularly placed in the placement box, the phenomenon that the parts shake and collide with one another in the infiltration working process so as to result in damage of the product is avoided, the parts are independently placed, so that infiltration is uniform, the product quality is improved, and every two matrixes are separated by limiting stop blocks so as to exert large pressure on the parts.

Description

technical field [0001] The invention relates to the field of engine sand core manufacturing, in particular to an engine sand core impregnation tool. Background technique [0002] At present, when manufacturing engine sand cores, it is usually necessary to place the sand core parts in a special solution for impregnation treatment to repair the sand holes that may exist in the sand core and improve the quality of the sand core products. During the impregnation treatment, the components are usually placed in a box and directly immersed in a special solution for impregnation treatment. However, when the components are placed in the box, collisions are likely to occur, resulting in damage to the components, a high defect rate, and the parts are connected. The position is easy to cause uneven impregnation. Therefore, it is particularly important to solve the problems of easily knocked parts and uneven impregnation in the impregnation work of the engine. Contents of the inventio...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the purpose of the present invention is to provide an engine sand core impregnation tool, which places the product through the placement box, and fixes the parts through the spacer on the base, and makes the parts regularly placed in the placement box. During the impregnation work, the parts will not shake and collide with each other, resulting in product damage, and each part is placed independently, and the impregnation is uniform, which solves the problems of easy bumping of parts and uneven impregnation in the impregnation work of the engine
