The present invention realizes that the injection moulding vulcanization of oil field blowout preventer glue core comprises the steps: that (1) lay the preventer iron core at counterdie; (2) counterdie and preventer iron core move in the sulfuration mechanism and position; (3) the fixing counterdie of magnechuck energising; (4) vulcanizer matched moulds; (5) vulcanizer lock ring locked mode; (6) injection nozzle and mould pressing; (7) injection device is injected into die cavity with sizing material and realizes that the preventer iron core covers glue; (8) sulfuration; (9) injection nozzle is deviate from the mold injects mouth; (10) plunger drives upper and lower mould decline, and dirty guidance tape separates with the upper reaches guidance tape, cleaning runner glue; (11) behind the cleaning runner glue, plunger rises again, drives mould and rises, and patrix and counterdie are locked again; (12) throw off lock ring; (13) counterdie descends with the oil cylinder plunger, opens mould; (14) stripper apparatus is deviate from patrix with the preventer that vulcanizates; (15) counterdie continues to drop to the oil cylinder place, the magnechuck dead electricity, and counterdie is removable state; (16) counterdie and goods shift out machine and enter guide rail; (17) hang and get goods, sulfidation finishes.So far, finish the whole injection adhesive-coating vulcanization process of preventer and also can come and go repetition.
Step (1) is: when injection glue core vulcanizing equipment was in original position, the various devices of equipment also were in original position, and counterdie is placed in the preventer iron core in the appropriate location of counterdie on the loading and unloading track at this moment.
Step (2) is: after iron core was settled and finished, counterdie and iron core advanced in the vulcanizer by the push-pull device at fixed that connects with bearing pin, and the location.
Step (3) is: after finished counterdie location, the magnechuck that is installed in counterdie got electric, and counterdie is produced magnetic attraction and fixes.
Step (4) is: after counterdie is fixing, and the vulcanizer matched moulds, it rises plunger by hydraulic power, the driving magnechuck moves up, and then drives the counterdie rising, when counterdie contacts the back and produces predetermined clamp force with patrix, the operation of vulcanizer matched moulds is finished in the plunger stop motion this moment.
Step (5) is: after locked mode finished, lock ring turned to the appropriate location by the driving catch means that connects with bearing pin with lock ring, with mould is locked up and down, finished lock ring locked mode process.
Step (6) is: after the lock ring locked mode finishes, the motor of press fit device is by the reduction box drive screw turns, and then the reduction box that driving is connected with nut moves as axial advancement along front and back line slideway and guide pillar, injection device and nozzle are moved forward synchronously, when nozzle contact mold runner mouth, pressure force increases gradually, when pressure force reaches the tonnage that presets, make the sensor that is installed in the press fit device send signal, press fit device motor dead electricity, stop operating, finish nozzle and mould pressing process.
Step (7) is: after the pressing process finishes, sizing material enters the branch flow passage of runner lower plate by injection port, runner by the runner lower plate is injected into die cavity again, when sizing material is filled with die cavity and is reached predetermined pressure, the pressure tester that is installed in head sends signal, cut off main motor power, injection device stops injection, finishes blowout preventer injection rubber-moulding process.
Step (8) is: after the moulding of injection glue core finished, Circulation and Hot Oil Spray constant temperature vulcanization plant vulcanized semi-products, sets corresponding cure time according to the size of goods, and when reaching cure time, sulfidation finishes.
Step (9) is: after sulfuration finished, the nozzle that is connected injection device was by press fit device, and the rotation direction opposite with stitching operation makes nozzle and injection device retreat into certain position.
Step (10) is: after injection nozzle is deviate from the mold injects mouth, open the spanner that connects between patrix and the runner plate.Start the oil cylinder plunger system, plunger drives entire die and descends, and keeps at a certain distance away with runner plate, then runner is carried out gel resin.
Step (11) is: behind the cleaning sizing material, plunger rises again, drives mould and rises to original position, and close the runner plate spanner, and patrix is fixed.
Step (12) is: fixedly behind the patrix, start and the motor that is installed in counterdie driving catch means, and then drive screw pair, make the nut that is connected in the lock ring hinge produce axially-movable, drive lock ring and rotate, the realization patrix is thrown off the operation of lock ring.
Step (13) is: after counterdie is thrown off lock ring, descend with the oil cylinder plunger, mould is opened certain position.
Step (14) is: after counterdie is opened, pass through time-delay relay, in setting-up time, send motor, decelerator, nut, the screw rod of signal enabling stripper apparatus, make demoulding push rod eject the preventer goods, guarantee that goods remain on the position of counterdie, for continuous operation is down prepared, when ejection behind desired location, stripper apparatus automatically resets.
Step (15) is: after goods ejected, counterdie dropped to the precalculated position, and mould sucker dead electricity is prepared for continuing operation down.
Step (16) is: after the mould sucker dead electricity, start motor, decelerator, the nut of mould shifting device, and then drive screw is done axially-movable and driven counterdie and goods and shift out in the machine to outside track.
Step (17) is: after counterdie and preventer goods moved to outside track, auxiliary crane gear hung out the preventer goods outside the mould.
The present invention compared with prior art has the following advantages and effect: the one, realize that continuous injection adhesive-coating moulding replaces the traditional batch pressure injection to cover gum forming; The 2nd, realize that mold-in injection pressure controllable operating replaces the controlled operation of traditional mould external pressure; The 3rd, realize that the shifting formwork injection replaces traditional single mode pressure injection; The 4th, replace vulcanisation operation in the single machine of tradition with the outer difunctional vulcanisation operation of machine in the realization machine.End is got up, and it is simple that the present invention has technology, product compactness and good uniformity, Functionality, quality and appealing design and long service life; Quality of item precision and stability are good; The production efficiency height; Conservation reduces cost, and is suitable for large-scale promotion application; Mechanization, automaticity height.

Behind the counterdie 48 own unlocking links 77, start oil cylinder 43 plungers 44 systems once more, counterdie 48 is descended with oil cylinder plunger 44, and mould 48,49 is opened, arrive preposition until die sinking; When counterdie 48 begins to descend, pass through time-delay relay, make the motor 84, decelerator 85, nut 89, the screw rod 92 that in setting-up time, send signal enabling stripper apparatus 8, make demoulding push rod 78 eject the preventer goods, guarantee that goods remain on the position of counterdie 48, when the push rod 78 of stripper apparatus 8 arrived desired location, stripper apparatus 8 automatically reset; When counterdie 48 drops to the precalculated position, magnechuck 60 dead electricity of mould, counterdie 48 is in does not have the electricity condition that has that connects, start this moment and the motor 108, decelerator 109, the nut 110 that are installed in the mould shifting device 105 of counterdie 48 hinges, and then drive spiral and do axially-movable and drive counterdie 48 and goods and shift out in the machine to the outer roller-way 107 of shifting formwork support 106; During roller-way 107, auxiliary crane gear hangs out the preventer goods outside the mould outside counterdie 48 and preventer goods move to.So far the oil field blowout preventer injection adhesive-coating vulcanization process finishes, and enters the circulation production cycle by above-mentioned steps.
