Description
Technical field
The present invention relates to the processing method of packing element, in particular to a kind of packing element mold and packer rubber
The processing method of cylinder.
Background technique
Packer be oil field well recover the oil a kind of key tool, be widely used in oil field dispensing, separate zone stimulation, pressure break,
The several work purposes such as oil production by layer, mechanical pipe water blockoff need.Chief component of the packing element as packer, its quality
The normal use effect of packer is directly influenced, service life etc. plays conclusive in packer setting work use
Effect.When packing element bears higher differential pressure in the high temperature environment, packing element is easy to make packing element lose the effect of setting by pressure break, thus
The use of packer is caused to fail.High temperature and pressure packing element used at present, scientific and technical personnel are in packing element shape and packing element
A large amount of improvement is done in terms of mold, but there are some problems.
The product vertical for packing element inner wall, structure is relatively simple, can be with by sizing material metaideophone technique, injection technique etc.
Produce preferable rubber packing element product, such as " rubber industry " " mold of Wel packing heavy wall packing element of volume 47 in 2000
Structure and sulfuration process " inquires into the mould structure and sulfuration process of packing element；But the envelope more complicated for structure
Every device packing element, the especially inner wall design product that has concaveconvex shape will design detachable mold core, specific structure as shown in Figure 1,
So that mould structure design is excessively complicated, it is not easy modulus in packing element manufacturing process, production efficiency is low, yield rate is low.
Therefore, a kind of simple packing element mold and packing element preparation method are found, is guaranteeing product quality
Under conditions of, simplify mould structure and preparation method as far as possible, packing element product is made to be easy to modulus, and can be improved packing element production
Efficiency and finished product rate.
Summary of the invention
In order to solve, packing element mold in the prior art is complicated, packing element production efficiency is low and finished product
The low technical problem of rate, the present invention provides a kind of packing element molds.
In order to solve the above-mentioned technical problem, the invention adopts the following technical scheme:
A kind of packing element mold, including lower template, middle template, mold core and upper diaphragm plate, the middle template are detachably pacified
In the lower template, the mold core is located at the middle template center, and the lower end of the mold core and the lower template pass through pin
Hole mode is located by connecting, and the space that can hold packing element ingredient is formed between the mold core and the middle template, the cope plate can
Folding is mounted on above the middle template.
Preferably, handle is arranged in the lower template, middle template and cope plate outer surface, to facilitate open-close module to pick and place glue
Material and packing element.
In order to solve the above technical problems, being specifically included the present invention also provides a kind of method for processing packing element
Following steps:
S1, by the rubber material being kneaded in the multiple Bao Tonghou clot of open mill at more slightly smaller than plunger-type extruder barrel
Rubber volume；Specifically by the rubber material being kneaded on a mill it is thin it is 3-5 times logical after, the rubber of suitable dimension in order to obtain
Volume adjusts open mill gum-retaining plate to one fixed width, and adjusts open mill roll spacing, again feeding Bao Tonghou rubber material, clot at
The rubber volume more slightly smaller than plunger-type extruder barrel；
S2, rubber volume filled in into preheated plunger-type extruder barrel in advance, while mouth mold of corresponding size being installed, open
Dynamic plunger-type extruder by rubber size is by extruder and mouth mold is preforming is extruded into tubular embryo material, and intercepts certain length
Packing element embryo material it is stand-by；
S3, preheated packing element molding die removed from compression molding, then the packing element embryo material intercepted is filled in into mould
In tool, entire mold is pushed into vulcanizing press, molds press cure, after the completion of vulcanizing, removes mold from vulcanizing press,
Packing element is taken out, preferably, vulcanization time is 20~50min, curing temperature is 160~180 DEG C；
S4, the packing element being molded is put into baking oven, control heating carries out post vulcanization, after the completion of post vulcanization,
Packing element semi-finished product are taken out, preferably, the post vulcanization time is 12~23min, post vulcanization temperature is 200~230
DEG C, control the 25 DEG C/h of rate of heating.
S5, installation requirement packing element Mechanical Processing Center to packing element semi-finished product carry out turnery processing, complete needed for ruler
Very little and structure packing element.
Present approach provides the processing methods of a kind of packing element mold and packing element.Utilize simple glue
Cylinder mould tool can produce complicated packing element, solve the problems, such as that existing packer mould structure is complicated, existing mould
Tool technology not only includes lower template, handle, mold core, middle template, cope plate, it is also necessary to Glass cement squeezing device, pressure injection head and with hole for injecting glue
Cope plate, be specifically shown in attached drawing 1, complicated packing element mould structure brings puzzlement to production, while especially inner wall has male and fomale(M&F)
Packing element production when modulus it is difficult, the structures design challenges such as die strip breakdown mold core.There is above technical scheme can be with this hair
The processing method of bright offer, packing element manufacturing process is simple, and stable product quality is good, and production efficiency is higher, yield rate is higher.
