Description

Technical Field

[0001] The utility model belongs to the technical field of sand box cleaning, and particularly relates to a sand box cleaning mechanism for a molding machine. Background Technique

[0002] The sand box of a molding machine is a casting device used for manufacturing sand molds. Its main functions are: filling sand, filling loose molding sand into the sand box; compacting the molding sand, making the loose molding sand in the sand box compact through different methods such as vibration compaction, pressure compaction, vibration-pressure compaction, and injection compaction, so that the sand mold has the necessary strength during processes such as handling and pouring; drawing the pattern, using different mechanisms to take out the pattern from the compacted sand mold. The cleaning of the inner wall of the sand box of a static pressure molding machine is an important link in the production process of sand mold making and also one of the difficulties. It is particularly more important and difficult to clean a thin sand box with a net-shaped reinforcing rib plate. During the processes of compaction, pouring, and demolding in the molding process, sand spots and sand blocks will remain on the inner wall of the sand box and the side of the rib plate. If the cleaning is not thorough, the sand spots and sand blocks will gradually accumulate and harden, directly leading to molding failure and sand box collapse.

[0003] After retrieval, for the Chinese patent "A Sand Box Cleaning Mechanism for a Static Pressure Molding Machine", the authorization announcement number is "CN220259024 U". This patented technology is provided with a first electric push rod, a fixed clamp, an operating table, and a second slider. By extending the output end of the first electric push rod, the fixed clamp is brought into contact with both sides of the sand box. The sand box can be firmly fixed by the fixed clamp. Subsequently, by rotating the output end of the second motor, the second lead screw can be rotated, so that the two second sliders move up and down along the installation direction of the second lead screw. Subsequently, by rotating the output end of the fourth motor, the first electric push rod on the right side can be controlled to rotate, and by rotating, the opening of the sand box is turned downward, and the sand and gravel cleaned from the inside of the sand box will fall from the inside of the sand box, improving the cleaning efficiency of the inside of the sand box and avoiding dust residue inside the sand box.

[0004] Although this patented technology solves the problems that when the existing sand box cleaning device is in use, it cannot comprehensively clean the solidified dust on the inner wall of the sand box, resulting in poor cleaning effect; second, after cleaning the sand box, it cannot clean the dust cleaned out, resulting in sand and gravel residue inside the sand box all the time and affecting the use. However, this patented technology inverts the sand box and uses an electric brush to clean the inside of the sand box. This cleaning method will cause dust to be raised, and the raised dust will float back into the sand box again, resulting in the sand box not being completely cleaned. Therefore, a sand box cleaning mechanism for a molding machine is proposed to solve the above problems. Content of the Utility Model
