Abstract

The invention discloses a packer rubber barrel die device. A rubber barrel forming die is included. A glue injection barrel is arranged at the upper portion of the rubber barrel forming die and is ofa hollow cylinder structure. The two sides of the glue injection barrel are symmetrically connected with a pair of handles I. A pressing injection head is arranged in the glue injection barrel and canbe freely separated from the glue injection barrel. The packer rubber barrel die device is reasonable in structure design, and fusing and flowing distribution of sizing materials before the sizing materials flow into the die are optimized. Through the design of a flow guiding groove, the material temperature before the sizing materials enter a die cavity can be better increased, it is guaranteedthat the sizing materials injected into the die cavity can be sufficiently fused, and accordingly, radial and axial cracking risks during rubber barrel pressure bearing setting are reduced. It can beguaranteed that the die structure is simple and machining is convenient, and the rubber barrel product quality is improved as well.

Description

technical field [0001] The invention relates to the field of seal manufacturing, in particular to a packer rubber cylinder mold device and a rubber cylinder preparation method. Background technique [0002] Packer is a key tool for downhole oil production in oilfields, and is widely used in oilfield separate injection, layered reconstruction, fracturing, layered oil recovery, mechanical pipeline water plugging and other operational purposes. As the main component of the packer, the quality of the rubber cartridge directly affects the normal use effect and service life of the packer, and plays a decisive role in the use of the packer setting work. When the rubber sleeve is subjected to a high pressure difference in a high-temperature environment, the rubber sleeve is easily fractured, causing the rubber sleeve to lose its setting function, resulting in the failure of the packer. For the currently used high temperature and high pressure packer rubber cartridges, scientific an...
