Description

Technical Field

[0002] Foam board is a lightweight, porous plastic board, mainly made of materials such as polystyrene (EPS) or extruded polystyrene (XPS). It has good thermal insulation properties and is often used in building insulation, packaging materials and advertising decoration.

[0003] In existing technology, during foaming, workers place the prepared sheet on a template, then close the upper and lower templates, while simultaneously moving the hydraulic piston below the foaming machine upwards to ensure the template is tightly closed. After closing, heating is performed, and the foaming agent in the sheet begins to decompose and generate gas, causing the sheet to expand. Then, the template is quickly opened, and the sheet continues to expand, popping out with a bang, thus completing the foaming process.

[0004] However, in the existing foam board foaming process, it is inconvenient to carry out the foaming and molding of dual-density foam boards, and it is inconvenient to flexibly control the injection of dual-density materials, which affects the processing effect. Therefore, there is an urgent need for a dual-density foam board foaming and molding device. Utility Model Content
