Abstract
The invention discloses a vulcanization process and a vulcanization tool of an air spring rubber capsule. According to the invention, a capsule is arranged in an inner cavity of a vulcanization mold forming mold. An air spring rubber capsule body is placed in the capsule in the vulcanization mold. High-pressure gas is blown into the air spring rubber capsule body through the vulcanization mold, so that the expended air spring rubber capsule body is firmly pressed against the capsule and the capsule is firmly pressed against the forming mold inner cavity wall of the vulcanization mold. The vulcanization mold is heated, and a heating and vulcanization treatment is carried out upon the air spring rubber capsule body through the heated capsule. With the vulcanization process provided by the invention, a finished product qualification rate of processed micro sleeve-type air spring rubber capsules is higher than 99%. The processed micro sleeve-type air spring rubber capsules are advantaged in uniform material quality, no gas bubble, long service life, good air tightness, good comfortableness, and the like.

Technical field
The present invention relates to a kind of sulfuration process and sulfurizing mould of air spring rubber utricule, belong to air spring rubber utricule manufacture technology field.
Background technology
At present, miniature air spring capsule generally adopts hard core vulcanization process to vulcanize processing, and this method is that product directly is fitted on the metal mandrel of high temperature high voltage resistant, and is placed in the mould and directly vulcanizes.Adopt the colloid of the air spring capsule of existing this vulcanization process production to exist the inequality of being heated, the capsule variable thickness causes; Cord distributes and stretches irregular; Problem such as serious wear when the colloid part is easy to generate bubble, depanning; Need process once more, therefore, its product also exists and is prone to aging, technical problems such as lack service life, easy gas leakage.So the vulcanizing treatment mode of existing rubber air spring capsule still is not ideal enough.
Summary of the invention
The objective of the invention is: a kind of be heated sulfuration process and sulfurizing mould even, that be difficult for the air spring rubber utricule of generation bubble, yield rate height, long service life are provided, to overcome the deficiency of prior art.
The sulfuration process that is achieved in that a kind of air spring rubber utricule of the present invention of the present invention is when the air spring rubber utricule that adopts sulfurizing mould to not moulding carries out vulcanizing treatment; A capsule is set in the inner chamber of sulfurizing mould shaping mould earlier; Then the air spring rubber utricule is put into the capsule of sulfurizing mould; In the air spring rubber utricule, be blown into gases at high pressure through sulfurizing mould again; The air spring rubber utricule is expanded; Air spring rubber utricule and capsule after the expansion closely fit together, and capsule is closely overlayed on the shaping mould internal chamber wall of sulfurizing mould, and then sulfurizing mould is heated; Through heated capsule the air spring rubber utricule is carried out baking and handle, can make the air spring rubber utricule obtain the uniform heating vulcanizing treatment through the mode of capsule in the baking mould molding mould like this.
The material of above-mentioned capsule is the high-temperature resistant rubber material.
The material of above-mentioned capsule is preferably the high-temperature resistant rubber material identical with the rubber envelop materials of air spring rubber utricule.
When sulfurizing mould is heated, adopt high-temperature high-pressure steam that sulfurizing mould is heated.
The temperature of above-mentioned high-temperature high-pressure steam is that 160 degree～175 degree, pressure are 2.0～2.3Mpa.
Above-mentioned is 10～15 minutes through the capsule in the sulfurizing mould of heating to the time that the air spring rubber utricule carries out vulcanizing treatment.
The pressure of the above-mentioned gases at high pressure that in the air spring rubber utricule, are blown into through sulfurizing mould is 2～3Mpa.
The sulfurizing mould that is used for of the present invention a kind of air spring rubber utricule of said method; Comprise and be used for the top die Connection Block and the dip mold Connection Block that are connected with press; On top die Connection Block and dip mold Connection Block, be fixed with top die and dip mold respectively; On top die and dip mold, be with overcoat respectively, be formed with the high steam cavity volume between its external sleeve and top die and the dip mold, be provided with the bottoming hole that communicates with the high steam cavity volume on the coat; In top die and dip mold, be separately installed with the air spring capsule shaping mould through bolt; In the inner chamber of air spring capsule shaping mould, be provided with capsule, on dip mold, be provided with the air inlet pipe that can be blown into gases at high pressure to the air spring rubber utricule of putting into capsule.
Be installed between the end face of the air spring capsule shaping mould in top die and the dip mold and be lined with sealing ring.
Owing to adopted technique scheme; The present invention comes that through heated capsule the air spring rubber utricule is carried out baking and handles; And, the air spring rubber utricule is expanded through being blown into the mode of gases at high pressure, processed air spring rubber utricule is heated equably; And the present invention is through adopting the mode of elastomeric material heating rubber workpiece; Can guarantee effectively that processed workpiece is heated evenly, and can prevent effectively that processed rubber workpiece from producing phenomenons such as bubble, thereby reach better vulcanizing treatment effect.Through the miniature sleeve formula rubber air spring capsule that sulfuration process of the present invention processed; Its product qualified rate can reach more than 99%, and the miniature sleeve formula rubber air spring capsule that processes have the colloid material evenly, no bubble, long service life, advantages such as air-tightness is good, comfort is good.
