Problems solved by technology
[0004] 1. The mold base in the mobile phone shell injection mold is usually designed in one piece. The side and bottom shell of the mobile phone shell are engraved at one time by an engraving machine. The requirements for the mold manufacturing machine are high, and the production cost is relatively high.
[0005] 2. Due to the integrated design of the mold base in the mobile phone shell injection mold, for different appearance models of mobile phones, the positions of the charging port, adjustment button and lock screen button on the side of the mobile phone are different, resulting in a single mold base can only be used for one Injection molding of the mobile phone shell, the practicability of the injection mold is low

The invention discloses a mobile phone shell injection mold. The mobile phone shell injection mold comprises a mold base, wherein the middle position of the upper end of the mold base is provided witha mold cavity, the back end of the mold cavity is provided with a first side edge mold, the right end of the mold cavity is provided with a second side edge mold, the front end of the mold cavity isprovided with a third side edge mold, the left end of the mold cavity is provided with a fourth side edge mold, the inner sides of the first side edge mold, the second side edge mold, the third side edge mold and the fourth side edge mold are provided with corresponding side edge convex columns, and the four corners of the mold base are provided with guide post seats. The side edge molds are detachably connected to the mold base through mounting studs, and a traditional integrated mobile phone shell injection mold base is converted into a split design, namely, four side edge molds and the bottom shell mold base are designed in a combination mode, so that the process and the operation difficulty in the production and manufacturing process of the mobile phone shell injection mold are greatlyreduced, and the production and manufacturing cost of the mobile phone shell injection mold is reduced.
Description
technical field [0001] The invention relates to the technical field of mold equipment, in particular to an injection mold for a mobile phone casing. Background technique [0002] Mobile phone case injection mold is a tool for producing plastic mobile phone cases, and it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. Mobile phone case injection molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics. Compression molds can be divided into three types: overflow type, semi-overflow type and non-overflow type according to the overflow method. The injection mold can ...
