Model 2B83

Core blowing machine. This semiautomated machine is intended for sand cores formation by tensile сore box filling with molding sand and its squeezing by compressed air.

The range of products for foundry industry manufactured by our factory includes 2B83 semiautomated core sand-blasting machine. This semiautomated machine is intended for sand cores formation by tensile сore box filling with molding sand and its squeezing by compressed air.

Field of application

Metal industry, foundry industry.

Product design

The semiautomated machine is a single-station unit which is started by pressing a button. Pressing the tensile сore box to the blow plate, clamping of the tensile сore box (for boxes with a vertical connector), injection of core sand mixture, waste air discharge and loading of the mixture into operating reservoir of the machine are carried out automatically.
The blow extension is equipped with interchangeable parts for obtaining cores with various configurations and it has a device that prevents mixture discharge. The operating table is equipped with a height-adjusting mechanism. The semiautomated machine pneumatic drive allows to adjust the duration of injection and discharge. It is equipped with a moisture separator and an air-oil lubricator. The structure of the reservoir provides proper injection of the mixture into the tensile сore box as well as a high degree of core squeezing. All mechanisms and units of the semiautomated machine are reliably protected from dust and dirt and easily accessible for maintenance and repair.
The semiautomated machine allows to improve output significantly and facilitate operations.
