Description
Technical field
The utility model relates to the unsteady mould emptier of a kind of enlarging elbow module dynamic model, belongs to the mould of plastics field.
Background technology
Adopt mould of plastics production enlarging elbow (pipe fitting); It is after the mould die sinking, to carry out that the enlarging elbow of conventional structure, its fuse are loosed core, and the shortcoming of existence is: after the mould die sinking; Product (enlarging elbow) has lost the fixing and protection of mould cavity to outer wall around it; Sometimes shrink reasons such as package power because of product, when loosing core, easily product is pulled, cause product rejection.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art; Provide a kind of and hold moving platen through pull bar; Moving platen wouldn't separate with solid plate in mould die sinking process, is at first loosed core by fuse, avoids pulling the unsteady mould emptier of enlarging elbow module dynamic model of product.
The technical scheme of the unsteady mould emptier of the utility model enlarging elbow module dynamic model is: comprise compound plate and following compound plate on the mould, last compound plate connects solid plate, and the mould pin is installed on the following compound plate, in the mould pin top board is set; Connect push rod on the top board, on the mould pin moving platen is installed, the enlarging elbow of moulding is arranged between moving platen and the solid plate; In the enlarging elbow fuse is arranged, fuse is driven by core-pulling mechanism looses core, and it is characterized in that on the sidewall of described solid plate pull bar being installed; Block tongue is installed in one sidewall of moving platen, and block tongue has the compression spring, and the block tongue head is shaped on the inclined-plane; On one sidewall of mould pin depression bar is installed, the bottom surface of pull bar and block tongue matches, and depression bar matches with the inclined-plane of block tongue head; Described push rod is provided with floating spring outward, and the top of floating spring contacts with the moving platen bottom surface, and the bottom of floating spring contacts with top board.
The enlarging elbow module dynamic model of the utility model mould emptier that floats during the demoulding, at first drives moving platen and solid plate die sinking by injection machine power; After the die sinking, floating spring withstands on the bottom surface of moving platen, and moving platen upwards floats under the elastic force of floating spring promotes; Simultaneously, the pull bar that the solid plate sidewall is installed is held the block tongue bottom surface of moving platen sidewall, makes moving platen can not separate with solid plate; It is fixed and protective effect to product together for moving platen and solid plate; At this moment, core-pulling mechanism is loosed core to fuse, can not pull product.After fuse was extracted out, mould continued die sinking, and the depression bar that is installed on the mould pin sidewall contacts with the inclined-plane of block tongue head; Block tongue is pressed in the moving platen, and pull bar and block tongue disengage, and moving platen separates (die sinking) with solid plate; After by push rod product being ejected mould at last, the demoulding is accomplished.This programme is spacing through spring floating and pull bar, and moving platen wouldn't be separated with solid plate, and core-pulling mechanism is loosed core to fuse simultaneously, does not pull product, and product rejection rate is low, and efficient is high.
Description of drawings
Fig. 1 is the unsteady mould emptier structural representation of the utility model enlarging elbow module dynamic model.
The specific embodiment
The utility model relates to the unsteady mould emptier of a kind of enlarging elbow module dynamic model, and is as shown in Figure 1, comprises compound plate 1 and following compound plate 2 on the mould; Last compound plate connects solid plate 3, and mould pin 4 is installed on the following compound plate, and top board 5 is set in the mould pin; Connect push rod 6 on the top board, moving platen 7 is installed on the mould pin 4, the enlarging elbow 8 of moulding is arranged between moving platen 7 and the solid plate 3; Fuse 9 is arranged in the enlarging elbow 8, and fuse 9 is driven by core-pulling mechanism looses core, and it is characterized in that on the sidewall of described solid plate 3 pull bar 14 being installed; Block tongue 15 is installed in one sidewall of moving platen 7, and block tongue 15 has compression spring 16, and block tongue 15 heads are shaped on inclined-plane 18; Depression bar 17 is installed on one sidewall of mould pin 4, and pull bar 14 matches with the bottom surface of block tongue 15, and depression bar 17 matches with the inclined-plane 18 of block tongue head; Be provided with floating spring 10 outside the described push rod 6, the top of floating spring 10 contacts with moving platen 7 bottom surfaces, and the bottom of floating spring 10 contacts with top board 5.During the demoulding, at first drive moving platen 7 and solid plate 3 die sinkings, after the die sinking by injection machine power; Floating spring 10 withstands on the bottom surface of moving platen 7, and moving platen 7 upwards floats under the elastic force of floating spring 10 promotes, simultaneously; The pull bar 14 that solid plate 3 sidewalls are installed is held block tongue 15 bottom surfaces of moving platens 7 sidewalls, makes moving platen 7 can not separate with solid plate 3, and it is fixed and protective effect to product together with solid plate 3 for moving platen 7; At this moment, core-pulling mechanism is loosed core to fuse, can not pull product.After fuse is extracted out; Mould continues die sinking, and the depression bar 17 that is installed on mould pin 4 sidewalls contacts with the inclined-plane 18 of block tongue 15 heads, and block tongue 15 is pressed in the moving platen 7; Pull bar 14 disengages with block tongue 15; Moving platen 7 separates (die sinking) with solid plate 3, by push rod 6 product is ejected mould at last after, the demoulding is accomplished.This programme is spacing through spring floating and pull bar, and moving platen wouldn't be separated with solid plate, and core-pulling mechanism is loosed core to fuse simultaneously, does not pull product, and product rejection rate is low, and efficient is high.
