High-speed fluid cleaning mechanism for casting sand mold

Abstract

The invention provides a high-speed fluid cleaning mechanism for a casting sand mold, which comprises impact components used for guiding high-pressure airflow towards the surface of a casting part anda driving component. Six groups of impact components are arranged in the circumferential direction of a fixed cylinder in an array manner; the impact component comprises a hard movable pipe rotationally arranged on a fixed cylinder, and the axial direction of the movable pipe is arranged in the radial direction of the fixed cylinder. The sand mold casting mold is vibrated and broken in the fixedcylinder; the two movable pipes are arranged in parallel up and down; the input end of the movable pipe is located outside the fixed cylinder and provided with an end cover in sealing connection fit with the movable pipe, and the output end of the movable pipe is located in the fixed cylinder and provided with a spray head in a communicating mode. The spray head is located between a steel wire cylinder and the fixed cylinder and extends outwards in the radial direction of the movable pipe, the input end of the spray head is connected and communicated with the output end of the movable pipe, the output end of the spray head points to the steel wire cylinder, and the driving component is used for driving the movable pipe to rotate around the axial direction.

Description

technical field [0001] The invention relates to the technical field of sand mold casting, in particular to a high-speed fluid cleaning mechanism for casting sand molds. Background technique [0002] Sand mold casting is a widely used casting form. As the name suggests, it is to use sand to make molds. Sand mold casting needs to put the finished part model or wooden model in the sand, then fill the sand around the pattern, and take out the pattern The sand is then used to form the mold. During use, the casting mold is kept for an appropriate time after pouring the liquid metal until the metal solidifies, after which the sand is removed, and after the parts are taken out, the casting mold is destroyed, so a new casting mold must be made for each casting. [0003] At present, the sand mold is generally vibrated by mechanical vibration, so that the sand is scattered and separated from the casting parts, so that the casting parts are taken out. The disadvantage is that after the...

Problems solved by technology

[0003] At present, the sand mold is generally vibrated by mechanical vibration, so that the sand is scattered and separated from the casting parts, so that the casting parts are taken out. The disadvantage is that after the sand mold is broken, the sticky sand on the surface of the casting parts is difficult to completely remove through mechanical vibration. It needs to be manually cleaned for the second time, which is time-consuming and laborious. In order to overcome the above-mentioned disadvantages, it is necessary to provide a cleaning mechanism with an ingenious structure and a simple principle that can completely remove the sticky sand on the surface of the casting parts.
