The present invention realizes the injection molding vulcanization of the rubber core of the oil field blowout preventer comprising the following steps: (1) placing the iron core of the blowout preventer on the lower mold; (2) moving the lower mold and the iron core of the blowout preventer to the vulcanization mechanism and positioning; (3) The electromagnetic chuck is energized to fix the lower mold; (4) The vulcanizing machine is closed; (5) The locking ring of the vulcanizing machine is locked; (6) The injection nozzle is pressed together with the mold; (7) The injection device injects the rubber into the cavity (8) vulcanization; (9) the injection nozzle comes out of the injection port of the mold; (10) the plunger drives the upper and lower molds to descend, the lower runner plate is separated from the upper runner plate, and the runner glue is cleaned; (11) After cleaning the runner glue, the plunger rises again, drives the mold to rise, and re-locks the upper mold and the lower mold; (12) disengages the lock ring; (13) the lower mold descends with the plunger of the oil cylinder, and opens the mold; (14) The demoulding device removes the vulcanized blowout preventer from the upper mold; (15) The lower mold continues to descend to the oil cylinder, the electromagnetic chuck loses power, and the lower mold is in a movable state; (16) The lower mold and the product are removed from the machine and enter Guide rail; (17) lift and get the product, and the vulcanization process ends. So far, the entire injection vulcanization process of the blowout preventer has been completed and can be repeated back and forth.

Step (1) is: when the injection rubber core vulcanization equipment is at the starting position, various devices of the equipment are also at the starting position, and the lower mold is on the loading and unloading track at this time, and the blowout preventer iron core is placed in the proper position of the lower mold .

Step (2) is: after the iron core is placed, the lower mold and the iron core are pushed into the vulcanizer through a push-pull device connected with the pin shaft, and positioned.

Step (3) is: after the positioning of the lower mold is completed, the electromagnetic sucker installed on the lower mold is energized to generate magnetic attraction to the lower mold and fix it.

Step (4) is: after the lower mold is fixed, the vulcanizer closes the mold, which lifts the plunger through hydraulic power, drives the electromagnetic chuck to move upward, and then drives the lower mold to rise, and the lower mold contacts the upper mold and produces a predetermined clamping mode. When the force is applied, the plunger stops moving, and the mold clamping operation of the vulcanizer is completed at this time.

Step (5) is: after the mold locking is finished, the lock ring is rotated to an appropriate position through the driving lock ring device connected with the pin shaft, and the upper and lower molds are locked, and the lock ring mold locking process is completed.

Step (6) is: after the lock ring mold clamping is completed, the motor of the pressing device drives the screw to rotate through the reduction box, and then drives the reduction box connected with the nut to move forward axially along the front and rear linear guide rails and guide columns, so that the injection device It moves forward synchronously with the nozzle. When the nozzle touches the mold runner, the pressing force gradually increases. When the pressing force reaches the preset tonnage, the sensor installed in the pressing device sends a signal, and the pressing device motor loses power. Stop the rotation to complete the process of pressing the nozzle and the mold.

Step (7) is: after the pressing process is completed, the rubber material enters the branch channel of the runner lower plate through the injection port, and then injects into the mold cavity through the runner channel of the lower runner plate.

When the vulcanization time is reached, the vulcanization process ends.

Step (9) is: after the vulcanization is completed, the nozzle connected to the injection device passes through the pressing device, and the rotation direction is opposite to the pressing operation, so that the nozzle and the injection device retreat to a certain position.

Step (10) is: open the wrench connecting the upper mold and the flow channel plate after the injection nozzle is detached from the injection port of the mould. Start the plunger system of the oil cylinder, the plunger drives the entire mold down, and has a certain distance from the runner plate, and then clears the runner.

Step (11) is: after cleaning the rubber material, the plunger rises again, drives the mold to rise to the original position, and closes the runner plate wrench to fix the upper mold.

Step (12) is: after fixing the upper mold, start the motor installed on the lower mold to drive the lock ring device, and then drive the screw pair to make the nut connected to the lock ring hinge produce axial movement, drive the lock ring to rotate, and realize the upper mold release Operation of the lock ring.

Step (13) is: after the lower die is disengaged from the locking ring, the plunger of the oil cylinder descends to open the die to a certain position.

Step (14) is: after the lower mold is opened, a signal is sent to start the motor, reducer, nut, and screw of the demoulding device within the set time through the delay relay, so that the demoulding ejector rod is ejected from the BOP product, ensuring The product is kept at the position of the lower mold to prepare for the next process. When the ejector is pushed to the set position, the demoulding device automatically resets.

Step (15) is: after the product is ejected, the lower mold is lowered to a predetermined position, and the mold suction cup is de-energized to prepare for the next subsequent process.

Step (16) is: after the mold sucker is powered off, start the motor, reducer, and nut of the mold moving device, and then drive the screw to move axially to drive the lower mold and the product out of the machine to the outer track.

Step (17) is: after the lower mold and the blowout preventer product are moved to the outer track, the auxiliary lifting equipment lifts the blowout preventer product out of the mold.

Compared with the prior art, the present invention has the following advantages and effects: one is to realize continuous injection molding to replace the traditional intermittent pressure injection molding; the other is to realize the controllable operation of the injection pressure in the mold instead of the controllable operation of the traditional external pressure ; The third is to realize the shifting injection instead of the traditional single-mode injection; the fourth is to realize the dual-function vulcanization operation inside the machine and outside the machine instead of the traditional single vulcanization operation inside the machine.
