The injection mold is a jig for quickly forming plastic products. The injection mold consists of a movable mold and a fixed mold, wherein the movable mold is arranged on a movable template of the injection molding machine, and the fixed mold is arranged on a fixed template of the injection molding machine. And when the mold is opened, the movable mold is separated from the fixed mold so as to take out the plastic product. The mold mainly comprises a pouring system, a temperature adjusting system, a forming part and a structural part. Where the runner system and the molded part are the parts in direct contact with the plastic and vary with the plastic and the article, the most complex and variable part in the mold that requires the highest finish and precision of the finish. The pouring system is a runner part before plastic enters a cavity from a nozzle, and comprises a main runner, a cold material cavity, a sub-runner, a pouring gate and the like. The molded parts refer to various parts forming the shape of a product, and include a movable mold, a fixed mold, a cavity, a core, a molding rod, an exhaust port and the like.

The ink cylinder assembly comprises an upper cover, an ink cylinder, a piston body and a bottom cover respectively, and when the ink cylinder assembly is used, the upper cover is removed, and the opening of the ink cylinder is in butt joint with an ink inlet of a copying machine or a printer. When the copying machine is in a working state, a certain negative pressure is formed in the ink cylinder along with the gradual reduction of the ink, so that the piston body moves upwards; when the ink is used up, the piston body will move up to the top of the cylinder. Because ink cylinder one end is helicitic texture, present common ink cylinder injection mold is for taking off the material in order to make things convenient for, generally sets up mould shaping part whole into two lamella combinations (ha fu mould) structure, but two lamella integrated configuration die cavities will lead to the ink cylinder surface to produce two axial joint lines, lead to ink cylinder surface quality to reduce, for this reason we propose the ink cylinder injection mold structure of duplicator in order to solve the above-mentioned problem that proposes.
