Self-adaptive injection molding amount automatic injection molding opening sealing device for electromechanical injection mold

Abstract

The invention relates to the technical field of mechanical and electromechanical equipment mold manufacturing, and discloses a self-adaptive injection molding amount automatic injection molding opening sealing device for an electromechanical injection mold. The self-adaptive injection molding amount automatic injection molding opening sealing device comprises an injection molding head, an injection molding pipe is movably connected with one end of the injection molding head, an exhaust hole is formed in the surface of the injection molding pipe, a floating plate is movably connected with the inner wall of the exhaust hole, an elastic seat is fixedly connected with the surface of the floating plate, a rotating rod is movably connected with the surface of the floating plate, a pressing plate is movably connected with the other end of the rotating rod, a flexible pipe is movably connected with the other side face of a lantern ring, and a push rod is movably connected with the other end of the flexible pipe. A one-way valve is movably connected with the other end of the push rod, a push plate is movably connected with the other end, away from the push rod, of the one-way valve, and an arc-shaped plate is fixedly connected to the other end of the push plate. The floating plate is pushed to move through molten plastic, the lantern ring is driven to extrude the flexible pipe, the push rod pushes the one-way valve to be closed, and the flexible pipe pushes the push plate, so that the arc-shaped plate pushes the injection molding head out of the injection molding pipe.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing for mechanical and electrical equipment, in particular to a device for automatically closing the injection port of an electromechanical injection mold with an adaptive injection volume. Background technique [0002] Mechanical and electrical equipment generally refers to machinery, electrical appliances and electrical automation equipment. In construction, it refers to the collective name of machinery and pipeline equipment other than geotechnical, carpentry, steel bars, and muddy water. It is different from hardware and refers to finished products that can achieve certain functions. Machinery Electromechanical equipment is mostly manufactured through special molds, such as stamping molds, injection molds, etc. [0003] Electromechanical equipment needs to carry out injection molding of plastic components such as casings. During injection molding, too much injection volume will lead to ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for automatically closing the injection port of an electromechanical injection mold with an adaptive injection volume, which has the functions of automatically controlling the injection volume, automatically closing the vent hole after injection molding, and automatically separating the injection head from the mold. Advantages, it solves the problems that the injection volume is difficult to control, and the opening and closing timing of the vent hole is difficult to control.
