Clamping and the injection mechanism of horizontal injection press are arranged successively along left and right; the rear end of the injection nozzle alignment clamping of the end of injection mechanism; during work, mould is opened along about level, Action of Gravity Field can be utilized automatically to fall, be easy to realize full automatic working after goods eject.
The mould of traditional horizontal injection press only has one deck die cavity, and each folding mould can only produce goods, and prouctiveness is low.In recent years.People design " laminated mould ", such as CN203792627U, CN201346830Y all disclose laminated mould, laminated mould structurally includes mould and moves plate, mould in plate, mould and determine plate, mould moves plate in plate, mould, mould is determined plate and is arranged in order from front to back, and mould moves plate in plate, mould, mould is determined to be provided with synchronous on-off transmission device between plate, mould moves in plate, mould and forms ground floor die cavity between plate, and in mould, plate and mould are determined to form second layer die cavity between plate.During use, mould is determined plate and is fixedly mounted on the solid plate of injection machine, mould moves plate and is arranged on the moving platen of injection machine, moving platen is driven to seesaw by matched moulds driving mechanism during work, under driving mechanism, the effect of synchronous on-off transmission device, in mould, plate and mould move plate and produce side-to-side movement, and in mould, the displacement of plate is constantly equal to that mould moves plate 1/2, in mould, plate is relative to the velocity of displacement equal and opposite in direction that plate determined by mould, mould moves plate, realizes two-layer die cavity synchronous on-off mould.Die cavity due to laminated mould is distributed in two or more aspect, combined type arrangement in an overlapping.Be the equal of be stacked together by how secondary mould, therefore the machine production multiplication of identical tonnage, significantly improves equipment productivity and speed of production.
The many collocation with horizontal injection press of laminated mould is produced, but, because the clamping of horizontal injection press and injection mechanism are arranged successively along left and right, the injection nozzle of existing laminated mould horizontal injection press can only aim at the rear end of clamping, therefore, the structure of existing laminated mould horizontal injection press is the asymmetric formulas in front and back, it has the two-layer die cavity of a set of injection mechanism and front and back, the injection nozzle of injection mechanism is positioned at mould and moves before plate, the fused materials of injection mechanism first flows into ground floor die cavity above, then flow into second layer die cavity below again, there is the shortcoming of mobile difficulty in existing injection mechanism.
