Description

Technical Field

[0001] The utility model relates to the technical field of demoulding devices, in particular to a demoulding device for an aluminum cover box. Background Art

[0002] Aluminum is a silvery-white light metal with ductility. The product is often made into rods, sheets, foils, powders, strips and filaments, and can form an oxide film in humid air to prevent metal corrosion. It is easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solutions, but difficult to dissolve in water. The content of aluminum in the earth's crust ranks third only to oxygen and silicon, and it is the most abundant metal element in the earth's crust. The development of the three major industries of aviation, construction, and automobiles requires that the material properties have the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new metal aluminum. It is widely used. Aluminum boxes are also widely used in life, especially some disposable aluminum lunch boxes, which can be quickly manufactured in batches by blistering.
