Lost foam casting equipment sand temperature regulator

The lost foam sand temperature regulator is a device specifically designed to regulate the temperature of sand, mainly used in lost foam casting production lines to meet specific requirements for sand temperature in production processes. The following is a detailed introduction to the lost foam sand temperature regulator:

1、 Main components

The disappearing mold sand temperature regulator usually consists of the following main parts:

Level detection device: used to detect the level of sand and ensure that the sand is stored in the appropriate amount in the equipment.

Sand storage unit: used to store a certain amount of sand and provide a continuous sand source for the production line.

Cooling unit: This is the core part of the equipment, with water cooling pipes evenly staggered and densely distributed inside. The sand exchanges heat with the water inside the water-cooled tube during the falling process, thereby reducing the sand temperature. There are two options for water-cooled tubes: seamless steel tubes and finned tubes. Finned tubes can increase the heat transfer area and improve cooling efficiency.

Sand dropping device: It usually adopts a rain shower sand dropping method, and the switch of the sand dropping device is automatically controlled by PLC and temperature detection device to ensure that the sand is transported to the next process only after meeting the temperature requirements.

Lower cone bucket, support legs and other auxiliary components: These components together form the overall structure of the equipment, ensuring its stability and reliability.

2、 Working principle

The working principle of the lost foam sand temperature regulator is relatively simple:

Sand enters the cooling unit from the sand storage unit.

During the falling process, the sand exchanges heat with the water inside the water-cooled tube, thereby reducing the sand temperature.

The cooled sand is transported to the next process through a sand dropping device.
