Sand mixing system for core shooter

Abstract

The invention discloses a sand mixing system for a core shooter for mixing and feeding inorganic sand at high efficiency. The sand mixing system comprises a rack, wherein a high platform is arranged on the rack; matched track and trolley are arranged on the high platform; the trolley can go back and forth through the track between a sand loading position and a sand unloading position; a sealed rotary spherical sand mixing device is arranged on the trolley; a sand blowing device is arranged on the rack; the outlet of the sand blowing device is formed above the inlet of the sand mixing device at the sand loading position; an ingredient storage tank is arranged on the rack; and a discharge hole of the ingredient storage tank is connected into the sand mixing device. The sand mixing system for the core shooter disclosed by the invention can ensure that inorganic sand, an adhesive and a curing agent are added according to the calibrated quality or ratio and calibrated time; sand blowing, quantitative sand adding, quantitative ingredient adding and sand mixing are finished; the sand can be unloaded by reaching appointed equipment; an online machine can quantitatively add sand in a time sharing manner; and the sand mixing system has enough mobility, and meets the core shooting requirements.

Description

technical field [0001] The invention relates to a sand mixing technology for a core shooter. Background technique [0002] In the whole process of casting production, the production of sand core is an important link. The sand core must not only have sufficient strength, accurate size, and clear outline, but also have good collapsibility. [0003] The sand mixer is used in foundry enterprises to mix resin sand and core sand. It is a sand mixing machine that can work continuously. The current open sand mixer (including bowl-shaped sand mixer) usually works intermittently. When using inorganic warm peritoneal sand for sand mixing, during the preparation of inorganic warm peritoneal sand, inorganic sand, adhesives, and curing agents It is added at different times during sand mixing. Since the open sand mixer (including bowl-shaped sand mixer) adopts a square structure or a hemispherical structure, and is equipped with a stirring rod or a horizontal rotating blade, there is a de...

Problems solved by technology

The current open sand mixer (including bowl-shaped sand mixer) usually works intermittently. When using inorganic warm peritoneal sand for sand mixing, during the preparation of inorganic warm peritoneal sand, inorganic sand, adhesives, and curing agents It is added at different times during sand mixing. Since the open sand mixer (including bowl-shaped sand mixer) adopts a square structure or a hemispherical structure, and is equipped with a stirring rod or a horizontal rotating blade, there is a dead angle during sand mixing, resulting in sand mixing. Uneven, and increase the sand mixing time and reduce the sand mixing efficiency

And the open structure will produce sand blowing phenomenon, which will affect the environment
