Abstract

The invention relates to an injection, rubberization and vulcanization device for an oilfield blowout preventer and a vulcanization molding method; the injection, rubberization and vulcanization device consists of a left and a right injection machines, a left and a right compressing fittings, a curing press, a die system, a die-locking device, a demoulding device and a left and a right guide frames; the left and right injection machines are connected with a side plate of the curing press through the front frame of the guide frame to form an organic integral body with the curing press; the compressing fitting is connected with the bottom of a reduction gearbox to realize front and rear movement of the injection machines; the curing press is provided with the die system, the die-locking device and the demoulding device; the guide frames are connected with the reduction gearbox and the injection machines through a guidepost and a linear guide to form an integral equipment whole machine. The device enhances the compactness and uniformity of rubberization and forming by the blowout preventer, delivers good product quality and long service life, ensures the stability of the quality, precision and performance between batches of products, has high production efficiency and good product qualified rate, saves raw materials, lowers energy consumption and delivers high automation degree and obvious benefits.

Description

Technical field: [0001] The invention relates to a vulcanization molding device and a vulcanization step method for oil field blowout preventer coating rubber, in particular to an oil field blowout preventer injection coating vulcanization equipment and a vulcanization molding method. Background technique: [0002] Oil field blowout preventer is a necessary tool to prevent blowout in oil wells, and it is also the most effective tool to prevent blowout. So far, there are two main methods for preparing oil field blowout preventers: one is to manually paste the rubber on the surface of the iron core of the blowout preventer, and then perform molding and vulcanization in a molding vulcanizer. Become a blowout preventer; the other is to place the iron core of the blowout preventer in the mold locked in the injection machine, and then press the rubber material pre-placed in the injection cylinder into the mold through a huge tonnage injection machine In the process, the rubber is...
