Beneficial effect of the present invention is, die station elevating drive mechanism transmission die station of moulding goods thermal forming device of the present invention is elevated more stable, stressedly more to balance, there will not be the uneven wear phenomenon between column and die station, guarantee the production and application that equipment is stable for a long time, therefore the present invention compared with prior art has outstanding substantive distinguishing features and significant progress.
Accompanying drawing explanation
Details and the operation principle of embodiments of the present invention and embodiment are described below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the perspective view of Fig. 1.
Detailed description of the invention
See accompanying drawing, the die station elevating drive mechanism of goods thermal forming device is moulded in present embodiment, include die station, die holder and column 5, described die station comprises die station 2, lower die station 3, described die holder comprises upper bolster 1, die shoe 4, and described column is vertically arranged, and die holder is positioned at the end of column, in the present embodiment, upper bolster, die shoe will lay respectively at the two ends up and down of column 5, be followed successively by upper bolster 1, upper die station 2, lower die station 3, die shoe 4 from top to bottom.Described die station to be set on column and die station on column by lifting action.Upper die station is used for arranging mold, and lower die station is used for arranging bed die.The downward action of upper die station, lower die station upwards action time matched moulds; The upwards action of upper die station, die sinking during the downward action of lower die station.
This die station elevating drive mechanism moulding goods thermal forming device also will comprise the transmission device of transmission die station lifting action on column.Described transmission device comprises the first front swing arm 6 and the second front swing arm 7, first rear-swing arm 8 and the second rear-swing arm 9, first front swing arm and the second front swing arm are hinged with die station respectively, first rear-swing arm and the second rear-swing arm are hinged with die holder respectively, first front swing arm and the first rear-swing arm hinged, second front swing arm and the second rear-swing arm hinged, swung by gear 11 engaged transmission between first rear-swing arm and the second rear-swing arm, described first front swing arm and the second front swing arm are symmetrical set, described first rear-swing arm and the second rear-swing arm are symmetrical set, described first rear-swing arm is also hinged with rocking arm 10, this rocking arm and transmission main shaft 12 eccentric gearing, transmission main shaft and power source (as motor) are in transmission connection, the first rear-swing arm is driven to swing by rocking arm.
See accompanying drawing, there is between upper bolster 1 and upper die station 2 first front swing arm 6 and the second front swing arm 7, first rear-swing arm 8 and the second rear-swing arm 9; Also corresponding between die shoe with lower die station have the first front swing arm 6 and the second front swing arm 7, first rear-swing arm 8 and the second rear-swing arm 9, its middle gear 11 can adopt sector gear, the root of rear-swing arm respectively arranges gear 11, rotating shaft with the hinged place of rear-swing arm on die holder is kept coaxial and arranges by the axial line of gear, described transmission main shaft 12 is arranged the action of eccentric wheel driving rocker.Rotating shaft place of each pin joint arranges lubricating oil pipe assembly (comprising lubricating oil pipe), more smooth when making each pin joint transmission.The both sides, front and back of moulding goods thermal forming device (as shaping mechanism, punch mechanism, trimming mechanism, the die assembly mainly above die station carries out) all arrange transmission device and are symmetrical arranged before and after transmission device.This die station elevating drive mechanism moulding goods thermal forming device is more stable when transmission die station is elevated, and stressedly more balances, and there will not be the uneven wear phenomenon between column and die station, guarantees the production and application that equipment is stable for a long time.
