Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, in particular to a mold for injection molding packaging products. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. Its advantages include high production speed, high efficiency, automated operation, a wide variety of designs and colors, shapes ranging from simple to complex, and sizes ranging from large to small. Furthermore, it produces precise product dimensions, is easily updated, and can produce complex shapes. Injection molding is suitable for mass production and the molding of complex products.

[0003] Plastics are made primarily of synthetic or natural polymer resins. After adding various additives, they become ductile under certain temperatures and pressures and can hold their shape after cooling. The process by which the natural or synthetic polymer resin molecules are molten and the additive molecules are evenly distributed around them is called plasticization. Existing molds, when used to injection mold plastic packaging products, experience slow cooling rates, which can affect product molding speed and production efficiency, significantly reducing the applicability of molds for injection-molded packaging products.
