Jolt squeeze molding machine without half-molds turning followed by final squeezing. This machine is intended for clay bonded molds manufacturing with 500×400 mm mold boxes in foundry workshops of serial production.

Field of application

Foundry workshops of serial production.

Product design:

Main components: jolt squeeze mechanism, traverse, column, pneumatic equipment, lubrication system, control panel.

Jolt squeeze mechanism located inside the bed performs the following operations: jolting, simultaneous jolting and squeezing, jolting with following squeezing, pattern drawing.
Molding sand squeezing in a mold box is produced in jolt mode by mutual collision of a jolting table and a ram. During simultaneous jolting and squeezing a squeeze piston upstrokes.
After pressing a mold box to traverse squeeze head squeezing is produced due to ram strokes over a jolting table. This squeezing mode is the most effective.
After simultaneous jolting and squeezing a squeeze piston downstrokes. When the squeeze piston is in the lower position a squeeze traverse moves back and drawing mechanism steps up automatically. Drawing mechanism pattern disengages squeezed half-molds from a pattern due to draw pins lifting. A half-mold is removed, pins are descended back.

Operation mode is semiautomated, step-by-step
