Description

Technical Field

[0001] The utility model belongs to the technical field of foaming molds, and in particular relates to a foaming device. Background Art

[0002] Foam molding is to fill the foaming resin directly into the mold, melt it under heat, form a saturated gas-liquid solution, and form a large number of tiny bubble nuclei through nucleation. The bubble nuclei grow and form foam plastic parts. Common refrigeration product inner boxes, such as refrigerators, freezers and other foamed objects, all require foaming molds. However, when existing foaming molds are used to foam longer products, a large amount of gas will be generated inside the material during the foaming process, which will cause internal support forces. For longer products, the constraints at both ends in the mold are relatively strong, while the constraints in the middle of the long side are relatively weak. This makes it impossible to effectively balance and offset the internal support forces in the middle of the long side, which in turn leads to deformation problems in the foaming position in the middle of the long side of the foamed object, resulting in an increase in product defective rates and may also reduce product performance and service life.
