Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a high-precision inverted composite mold. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise product dimensions. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. With the development of society, flip-chip molds have been put into use on a large scale.

[0003] The inventor has found in his daily work that most of the current injection molds are prone to loose fit between the upper and lower molds during production and processing, resulting in a gap between the upper and lower molds, causing a mold line to appear on the finished product, increasing the subsequent processing steps of the injection molded product, increasing the production cost of the product, and reducing the profit of the product. Improvements are needed. Utility Model Content
