Abstract
The invention relates to a quick die replacement mechanism for a low pressure casting machine. The mechanism comprises a frame (1), an upper die fixing plate (2), a lower die (3), a lower die fixing plate (4), an upper die (6), hydraulic oil cylinders (8), bolts (9) and latches (10), wherein two groups of hydraulic locking mechanisms are symmetrically arranged on each of the upper die fixing plate (2) and the lower die fixing plate (4). The mechanism is characterized in that the bolts (9) are pulled to be separated from the latches (10) by the hydraulic oil cylinders (8), so that the dies are separated from the fixing plates, and on the contrary, the bolts (9) are pushed to be inserted into the latches (10) by the hydraulic oil cylinders (8), so that the dies are locked on the fixing plates. The locking mechanisms are appropriately added on the basis of the conventional low pressure casting machine, so that die replacement time is shortened from at least half an hour to at most ten minutes, time and labor are greatly saved, the utilization rate of equipment is improved to the greatest extent, and the dies are quickly replaced.
Description
Technical field
The invention belongs to the metal casting machine technical field, especially about the fast mold change mechanism of air injection machine.
Background technology
Along with increasingly sharpening of market competition, all kinds of foundry goods goods update more and more faster, the coexistence kind is more and more, the situation of many kinds, small batch, the production of mixed flow JIT will become main flow in the production, in particular for the supporting enterprise of automobile industry, no matter which kind of cast product all will provide qualified products parallel, complete for different vehicles, on time.Therefore; the frequency of die change will be more and more higher with shorter and shorter the blanking time of die change, and corresponding air injection machine will increase downtime greatly; have a strong impact on production efficiency and machine utilization rate, delivery cycle prolongation, a large sum of investment can not effectively be repaid.This present situation has caused domestic and international air injection machine production and has used the attention of producer, in the low pressure casting automation, if can not effectively solve the quick die change problem, other production link automaticity the higher utilization rate that also is difficult to fully improve equipment, enhance productivity, that complete equipment also can only deserve to be called is physically fit, reaction flexibly " lame person ".
Summary of the invention
More need during mold exchange manually manually to loosen one by one with instrument or the problem of the inefficiency that exists of tighting a bolt for air injection machine; the object of the present invention is to provide a kind of fast mold change mechanism of air injection machine; on upper mould fixed plate and counterdie fixed head, to increase respectively by a cover hydraulic locking mechanism; only need to operate by outer button; mould can be dismantled fast after hydraulic lock was removed; after also only needing mould to put in place when new die is installed; the outer button operation; hydraulic locking mechanism gets final product the auto lock mould, reaches quick, laborsaving, safe purpose.
The technical solution used in the present invention is: the fast mold change mechanism of air injection machine, comprise frame, upper mould fixed plate, bed die, counterdie fixed head, mold, hydraulic jack, dead bolt and snap close, mold is fixed on the frame by upper mould fixed plate, bed die is fixed on the counterdie fixed head, on described upper mould fixed plate and the counterdie fixed head respectively symmetry respectively increase by two groups of hydraulic locking mechanisms, retaining mechanism is comprised of hydraulic jack, dead bolt and snap close, it is characterized in that: described hydraulic jack pulling dead bolt breaks away from snap close, and mould namely breaks away from fixed head; Otherwise hydraulic jack promotes dead bolt to be inserted in the snap close, and mould namely is locked on the fixed head.
Structure of the present invention, on the basis of not changing original low press structure, by suitable increase retaining mechanism, the replacing that makes mould from before the longest ten minutes till now minimum half an hour, from before minimum two people till now a people just can change quickly and easily a mold, greatly save time and manpower, improved to greatest extent the utilization rate of equipment, realized quick die change.
Description of drawings
Fig. 1 is the die-replacing structure of prior art.
Fig. 2 is structural representation of the present invention.
Among the figure: locked mode bolt, 8 hydraulic jacks, 9 dead bolts, 10 snap closes on 1 frame, 2 upper mould fixed plates, 3 bed dies, 4 counterdie fixed heads, 5 times locked mode bolts, 6 molds, 7.
The specific embodiment
Being known by Fig. 1, is the die-replacing structure of prior art.The die changing mechanism of air injection machine commonly used; formed by locked mode bolt on 1 frame, 2 upper mould fixed plates, 3 bed dies, 4 counterdie fixed heads, 5 times locked mode bolts, 6 molds, 7; the locked mode mode directly is fixed on mould on the fixed head 2 by bolt, needs manually to twist one by one bolt with instrument and comes more mold exchange.
Being known by Fig. 2, is structural representation of the present invention.Formed by 1 frame, 2 upper mould fixed plates, 3 bed dies, 4 counterdie fixed heads, 6 molds, 8 hydraulic jacks, 9 dead bolts, 10 snap closes, increase by four groups of retaining mechanisms at original upper mould fixed plate 2 and counterdie fixed head 4, retaining mechanism is comprised of hydraulic jack 8, dead bolt 9 and snap close 10.Hydraulic jack 8 pulling dead bolts 9 break away from snap close 10, and mould can break away from fixed head; Otherwise hydraulic jack 8 promotes dead bolt 9 to be inserted in the snap close 10, and mould can be locked on the fixed head like a cork.
During work, the mould board of packing into, with snap close 10 location, hydraulic jack 8 actions promote dead bolts 9 and insert in the snap closes 10, and mould can firmly be locked on the platen; When needing form removal, as long as hydraulic jack 8 pulling dead bolts 9 are broken away from snap closes 10, mould and lose coupling mechanism force, mould is with regard to fast changeable.
Claims (1)
1. the fast mold change mechanism of air injection machine, comprise frame (1), upper mould fixed plate (2), bed die (3), counterdie fixed head (4), mold (6), hydraulic jack (8), dead bolt (9), snap close (10), mold (6) is fixed on the frame (1) by upper mould fixed plate (2), bed die (3) is fixed on the counterdie fixed head (4), on described upper mould fixed plate (2) and the counterdie fixed head (4) respectively symmetry respectively increase by two groups of hydraulic locking mechanisms, retaining mechanism is by hydraulic jack (8), dead bolt (9) and snap close (10) form, it is characterized in that: described hydraulic jack (8) pulling dead bolt (9) breaks away from snap close (10), and mould namely breaks away from fixed head; Otherwise hydraulic jack (8) promotes dead bolt (9) to be inserted in the snap close (10), and mould namely is locked on the fixed head.
