The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As Fig. 1-shown in Figure 5, Bicolour double-density block press 1 of the present invention, comprise two footwear moulds, these two footwear moulds comprise backform 2, side form 3 and bed die respectively, described footwear mould is arranged on the same side of moulding press 1, described bed die comprises bed die 4 and secondary bed die 5, and this bed die 4 and secondary bed die 5 are loaded on die frame 7 respectively and are arranged on moulding press 1 workbench by die frame 7.Be provided with the chute 12 that pushes or pull out for described die frame 7 on moulding press 1 workbench, and be provided with corresponding slide rail 13 in die frame 7 bottoms, vice versa.Bed die 4 and secondary bed die 5 push or pull out in moulding press 1 by the slide rail 13 of die frame 7, and the pressure that is applied to described backform 2 or backform 2 and side form 3 is controlled by a pressure-regulating device.
Referring to Fig. 1 and Fig. 6, described backform 2 and side form 3 are connected in top hydraulic cylinder 21 and side hydraulic cylinder 22 by backform seat 9 and side form seat 10 respectively, described pressure-regulating device is a pilot-operated type electricity liquid ratio relief valve 25, it is arranged between the major loop and fuel tank 31 of hydraulic system, and this pilot-operated type electricity liquid ratio relief valve 25 is controlled by power amplifier by PLC.
Be provided with heater in described secondary bed die, this heater can be electric heater, is positioned in the secondary bed die 5 by bottoming hole 8, is used for the heating of secondary bed die 5, guarantees the curing temperature of sole in pressing process.
Referring to Fig. 4, Fig. 5 and Fig. 6, front end at a described bed die 4 and secondary bed die 5 is respectively equipped with magnetic block 6, and be respectively equipped with in the position of described chute 12 front ends of moulding press 1 workbench corresponding described magnetic block 6 near switch, wherein corresponding bed die 4 magnetic blocks 6 is used for exporting first control signal to described PLC near switch, make hydraulic circuit produce first pressure and 24 actions of control backform hydraulic cylinder magnetic valve, compacting outer shoe in order to control pilot-operated type electricity liquid ratio relief valve 25; And corresponding secondary bed die 5 magnetic blocks 6 be used for exporting second control signal near switch to described PLC, make hydraulic circuit produce second pressure in order to control control pilot-operated type electricity liquid ratio relief valve 25, and magnetic valve 24 actions of control backform hydraulic cylinder 21 and side form hydraulic cylinder 22, suppress outer shoe and internal layer sole and internal layer sole and upper of a shoe bonding.
As shown in Figure 6, be provided with synchronized on the pipeline between the oil return opening of described side hydraulic cylinder 22 and the magnetic valve 24, this synchronized is a synchronous oil cylinder 23, is used to guarantee both sides side form 3 same moved further.Also be provided with feed circuit between this external side hydraulic cylinder 22 and the hydraulic pump 30, this feed circuit is made up of solenoid directional control valve 24 and hydraulic control one-way valve 26, be used for when side hydraulic cylinder 22 is got back to the die sinking initial point synchronous fuel tank 23 and 22 repairings of side hydraulic cylinder, guarantee that the action of side form 3 of next circulation is synchronous.
The moulding press course of work of the present invention is as follows: earlier outer shoe rubber is attached on bed die 4, again bed die 4 is pushed the pressing die position of moulding press 1 workbench along chute 12, corresponding bed die 4 magnetic blocks 6 send first control signal near switch to PLC, PLC is by power amplifier control pilot-operated type electricity liquid ratio relief valve 25, thereby be set in the hydraulic main circuit first limiting pressure value, control solenoid directional control valve 24 actions of backform 2 simultaneously, control backform hydraulic cylinder 21 presses down, and carries out the compacting of outer shoe.After reaching setting pressure, pressure sensor 28 senders control solenoid directional control valve 24 dead electricity by 26 pairs of backform 2 pressurizes of hydraulic control one-way valve, are tentatively vulcanized outer shoe simultaneously.After reaching setting-up time, pressurize finishes, 24 die sinkings of PLC control solenoid directional control valve.Backform 2 moves upward, and the good outer shoe that is shaped is stayed in the backform 2.Pull out first bed die 4.And then having packaged upper of a shoe, second bed die 5 that has posted the internal layer sole pushes the pressing die position.At this moment, corresponding secondary bed die 5 magnetic blocks 6 send second control signal near switch to PLC, PLC is by power amplifier control pilot-operated type electricity liquid ratio relief valve 25, thereby be set in the hydraulic main circuit second limiting pressure value, control solenoid directional control valve 24 actions of the solenoid directional control valve 24 and the side form 3 of backform 2 simultaneously, backform hydraulic cylinder 21 is pressed down and both sides side form hydraulic cylinder 22 is inwardly pressed, because synchronous fuel tank 23 effects two side form hydraulic cylinders 22 same moved further, outer shoe and internal layer sole and internal layer sole and upper of a shoe are forced together, wherein pressure-regulating valve 27 is used to synchronous fuel tank 23 that back pressure is provided, and makes that moving of side form hydraulic cylinder 22 is more stable.When reaching setup pressure value, pressure sensor 28 senders are controlled each solenoid directional control valve 24 dead electricity, and each hydraulic control one-way valve 26 is respectively to backform 2 and side form 3 pressurizes, and the ectonexine sole is final sulfuration typing in the footwear mould.After reaching setting-up time, 24 die sinkings of PLC control solenoid directional control valve, backform 2 and side form 3 are return original position, take out secondary bed die 5, take off the footwear that press sole, finish a working cycles.
Being example with a station above is illustrated the course of work and the operation principle of moulding press of the present invention, in fact two stations can be simultaneously or the mold pressing of two soles that hocket processing, a people can finish the processing of a pair of shoes simultaneously, and its process operation is simpler, and working (machining) efficiency is higher.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
