Cleaning device for inner cavities of various lost foam molds

Abstract

The invention discloses a cleaning device for inner cavities of various lost foam molds. The cleaning device comprises a device cover plate and a motor box fixedly mounted at the top of the device cover plate, wherein a rotating cylinder is rotatably mounted at the center of the device cover plate through a bearing; the top of the rotating cylinder penetrates through the motor box and is rotatablyprovided with a rotating joint; the rotating cylinder in the motor box is in friction connection with a belt through a belt pulley; one side of the belt is in annular friction connection with a motor; the top of the motor is fixedly mounted on the inner wall of the top of the motor box; a bottom rotating shaft is rotatably mounted at the top of the device cover plate; the bottom end of the rotating cylinder penetrates through the bottom of the device cover plate and is fixedly welded to a rotating roller; arc-shaped columns are rotatably mounted on the two sides of the rotating roller throughrotating assemblies; a plurality of rolling wheels are rotatably embedded in the outer walls of the sides, away from the rotating roller, of the arc-shaped columns; fixing blocks are fixedly mountedat the bottoms of the ends, away from the rotating roller, of the arc-shaped columns; and clamping blocks are rotatably mounted at the bottoms of the fixing blocks through angle adjusting assemblies.

Description

technical field [0001] The invention relates to the technical field of mold cleaning, in particular to a device for cleaning inner cavities of various lost molds. Background technique [0002] Lost foam casting (also known as solid casting) is to bond and combine paraffin or foam models similar in size and shape to castings to form a model cluster. After brushing refractory paint and drying, it is buried in dry quartz sand for vibration molding. Down pouring, the model is vaporized, the liquid metal occupies the position of the model, solidified and cooled to form a new casting method. After the existing lost foam casting takes out the casting, the dry quartz sand in the inner cavity needs to be recycled and reused. However, the existing lost foam inner cavity has various styles, and it is easy to leave quartz sand on the inner cavity wall. The flushing to every corner of the inner cavity, and the cleaning efficiency is relatively low, so we propose a cleaning device for va...

After the existing lost foam casting takes out the casting, the dry quartz sand in the inner cavity needs to be recycled and reused. However, the existing lost foam inner cavity has various styles, and it is easy to leave quartz sand on the inner cavity wall. The flushing to every corner of the inner cavity, and the cleaning efficiency is relatively low, so we propose a cleaning device for various types of lost foam inner cavity to solve the above problems
