CORE MACHINE TYPE D-4, MODEL U-210
This machine produces cores and shell moulds by hot-box procedure.
Machine can work in manual, semiautomatic and automatic cycle.
Controlling electro box PLC control.
Starting by pedal, machine door closed and frame moves forward, when tool is closed, sand tank is lifted, machine turns for 180o and injects sand.
Keeping the machine in upper position (180o) wall depth of the core is timely regulated and machine goes to the basic position.
Machine moves left-right for 45o. It is timely regulated. If cores are simple and straight, it could be turned off.
After baking or gassing the tool is opened and the core remains in movable part of the tool. The movable part of the tool turns for 90 degreses over the lane for core reception and transport. With the knocker the core is automatically knocked out and it gets onto the lane, the lane moves for the core size towards the worker who overtakes the core from the lane and puts it away. Tilted half of the tool returns to vertical position, moves ahead, closes an continues the next cycles.
Advantages of this machine are
Completely automatic work cycle, cores are falling automatically on the line and machine starts a new cycle.
Robust and heavy cores can be produced on this machine.
