Core making machine

Product Description

The automatic vertical parting cold box core shooting machine is a high-efficiency core-making machine dedicated to valves, gearboxes, bearing chambers, boxes, and half-pipe sand cores. The machine has compact structure, convenient operation, and rapid action. Stable, long service life, low maintenance rate, etc. This machine adopts high-rigidity four-column frame structure. The horizontal moving car of sand barrel and blowing plate adopts bracket roller and side wheel guide structure, which operates fast and smoothly (no impact phenomenon of suspension structure); The vertical movement of sand barrel and blowing plate adopts four-axis guide, with high positioning accuracy and good sealing effect of joint surface. The vertical movement guide of worktable adopts thickened high-rigidity guide column, with high mold clamping accuracy, rapid acceleration and deceleration function of sand shooting cylinder and sand shooting head. The machine is equipped with an advanced YL-30A type full-automatic triethylamine gas generator. Its various process parameters can be set and modified on the display screen of the core launcher without regulating the internal components of the generator, thus eliminating potential safety hazards in control. The generator adopts high-efficiency explosion-proof heater, imported electric proportional valve, large flow pilot valve, non-pressure amine atomizing pump and other devices, which can realize automatic control of the whole process of triethylamine quantitative atomization and amine addition, heating, gasification, amine blowing and cleaning, the sand core can be completely cured in a few seconds, and the amount of amine used is very low. Under ideal conditions, the amount of amine used per ton of sand core is only 1-2L. The whole machine control adopts PLC program control, man-machine interface parameter setting, can realize the equipment automatic, manual, inching and automatic cycle four operation modes.
