Abstract

The invention discloses an O-shaped rubber ring injection mold and a method for processing an O-shaped rubber ring thereby and relates to the field of O-shaped rubber ring processing. The O-shaped rubber ring injection mold disclosed by the invention comprises an upper mold, a middle mold and a lower mold, wherein two crossing main runners are formed in the upper surface of the upper mold; runnerholes penetrating through the whole upper mold from top to bottom are respectively formed in two ends of each main runner; the middle mold is positioned below the upper mold; a diversion port corresponding to each runner hole of the upper mold is formed in the upper surface of the middle mold; the diversion port in the middle mold is a channel penetrating through the whole middle mold from top tobottom; an annular molding groove is formed around each diversion port in the upper surface of the middle mold; each molding groove is respectively communicated with the nearest diversion port by virtue of the corresponding diversion channel; and the lower mold is positioned below the middle mold. According to the O-shaped rubber ring injection mold disclosed by the invention, multiple O-shaped rubber rings can be efficiently produced by virtue of one-step injection, and the production efficiency of the O-shaped rubber rings is improved.

Description

technical field [0001] The invention relates to the field of O-shaped rubber ring processing, more specifically, to an O-shaped rubber ring injection mold and a method for processing the O-shaped rubber ring. Background technique [0002] O-shaped rubber ring is an annular rubber ring with a circular cross section, which is mainly used for mechanical parts to prevent the leakage of liquid and gaseous media under static conditions. In some cases, it can also be used for axial reciprocating motion and low-speed rotary motion. According to different conditions, different materials can be selected to adapt to it, and its application is more extensive. To sum up, the O-shaped rubber ring has simple structure and reliable sealing performance, and is widely used in various sealing fields. [0003] The development of rubber molding technology has gone through three stages: compression molding, injection molding and injection molding. At present, all three molding processes are in ...
