Sand molding machine base capable of uniformly feeding liquid and removing bubbles

Abstract

The invention relates to the technical field of sand molding, and discloses a sand molding machine base capable of uniformly feeding liquid and removing bubbles, the sand molding machine base comprises a rack, a mounting plate is slidably connected to the interior of the upper end of the rack, a positioning rod is fixedly connected to the lower surface of the mounting plate, and a positioning groove is formed in the side face, close to the positioning rod, of the rack; and telescopic rods are fixedly connected to the two sides of the lower surface of the mounting plate, reset springs wrap the outer sides of the telescopic rods, electromagnetic rods are fixedly connected to the interiors of the telescopic rods, a liquid bin is formed in the rack, and a baffle is rotationally connected to the interior of the liquid bin. The metal feeler lever is in contact with the metal strips on the upper side and the lower side in sequence, and the elastic cavity continuously expands and shrinks, so that shaking of the sand molding machine is increased, a solution in the sand molding machine can be more uniform, and the effects that the solution in the sand molding machine can be uniform, meanwhile, internal air can be exhausted, the quality of castings is improved, and the working efficiency is improved are achieved.

Description

technical field [0001] The invention relates to the technical field of sand molding, in particular to a sand molding machine base with uniform liquid entry and air bubble removal. Background technique [0002] During the pouring process of the sand molding machine, due to the sudden rise of the internal temperature and the strong change of cold and heat, a large amount of gas will be generated inside the pouring solution. Due to the continuous pouring of the external solution, the internal gas cannot be discharged in time, resulting in There will be air holes inside the casting, and at the same time, because the liquid is not uniform inside the sand mold, the material density of each part of the casting will change, and the quality of the casting will decline. [0003] In order to solve the above problems, the inventor provided a sand machine base with uniform liquid entry and air bubble removal. By shaking the mounting plate up and down, the positioning rod is in the positi...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sand machine base with uniform liquid entry and air bubble removal, which can make the internal solution uniform and discharge the internal air at the same time, which improves the quality of castings and improves work efficiency, and It can make all parts of the casting more uniform and facilitate the shaping of the casting. It solves the strong cold and heat changes, which will cause a large amount of gas inside the pouring solution. Due to the continuous pouring of the external solution, the internal gas cannot be discharged in time. , resulting in pores inside the casting, and at the same time, due to the unevenness of the liquid inside the sand mold, the material density of each part of the casting changes and the quality of the casting decreases.
