Abstract

The invention discloses a display shell injection mold with a drainage opening material cutting-away function, and belongs to the technical field of injection molds. The display shell injection mold comprises a front mold, a rear mold, an outer sprue and a drainage opening cutting mechanism; the front mold is clamped on the rear mold; the outer sprue is arranged on the front mold; the outer sprue is communicated with a cavity in the rear mold and the front mold; the drainage opening cutting mechanism is arranged in the rear mold; and the drainage opening cutting mechanism is pressed against a drainage opening communicated with the cavity. According to the invention, a first oil way controls a first lifting oil cylinder to descend and pulls cutters out of a guide sleeve, a second oil way controls a rotating oil cylinder to rotate and drive a cutter head to rotate, the cutter head rotates to send different cutters to the position below the guide sleeve, and the first oil way controls the first lifting oil cylinder to ascend and insert the cutters into the guide sleeve, so that replacement of the cutters can be completed; the injection mold does not need to be disassembled, the situation that production is delayed due to machine stagnation is avoided, the replacement operation process is simple and convenient, and the labor cost and the working time cost are saved.

Description

technical field [0001] The invention belongs to the technical field of injection molds, and in particular relates to an injection mold for a display casing with the function of cutting out nozzle material. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex-shaped products and other molding processing fields. This process is also used in the molding of display casings. However, after injection molding, there will be water holes on the display casing, which needs to be removed after the display casing is demoulded. Manual processing and removal is a waste of labor costs, so t...
