Abstract
The invention discloses a tire curing bladder moulding method. According to the tire curing bladder moulding method, mould assembly of an upper mould and a lower mould of a bladder mould is controlled to stop at a certain degree, so that a closed charging chamber is formed between the upper mould and the lower mould, and the closed charging chamber is connected with a mould cavity via an circular runner; at the same time, air in the mould cavity is removed using a vacuum device, so that vacuum degree of the mould cavity is controlled to be a certain value; a rubber material is injected into the charging chamber using a spray nozzle, wherein injection amount is controlled using a control system; after injection, pressurization is carried out so as to press the upper mould against the lower mould firmly, and extrude the rubber material into the mould cavity; when complete firm pressing of the mould is realized, a sprue and a vacuum mouth are blocked by a mould plate, so that the mould cavity becomes a closed system; the mould is dissembled after curing, an obtained tire curing bladder is detached from the upper mould under the action of compressed air delivered into the mould; and demoulding of the tire curing bladder is realized by jacking a lower tray.
Description
Technical field
The invention belongs to tire production technical field, be specifically related to a kind of tire curing bladder forming method.
Background technology
At present, the forming method of domestic tire curing bladder has two kinds, is respectively die pressing and injection, and die pressing exists charging and lacked meeting starved, and how feeded to run and emitted, overlap is large, and the problems such as became uneven.There is injection device complex structure in injection, processing difficulties, and cost is high, and because the mobility of sizing material is bad, required injection pressure and energy consumption are too large, and maintaining difficulty, noise is large.
Summary of the invention
The object of the invention is to, a kind of tire curing bladder forming method is provided, had both solved the problem that production cost is high, ensure again the quality of tire curing bladder.
Tire curing bladder forming method provided by the invention, realize by the following method: control on capsule die, counterdie matched moulds to a certain extent time stop matched moulds, at this moment upper, an enclosed feed compartment is formed between counterdie, this feed compartment is connected with die cavity by annular runner, by vacuum extractor, the air in die cavity is all taken away simultaneously, die cavity is made to form certain vacuum, then with nozzle, sizing material is injected into feed compartment, injection volume controls by control system, injection terminates, pressurization, upper, counterdie compresses, sizing material is expressed in die cavity simultaneously, after mould compresses completely, cast gate and vacuumize mouth and blocked by template, die cavity is made to form a closed system, mould is opened after sulfuration terminates, capsule first departs from patrix under the compressed air effect be blown into, then lower tray jack-up, capsule is deviate from.
Tire curing bladder forming method provided by the invention, its beneficial effect is: both solved the problem that production cost is high, ensures again the quality of tire curing bladder.
Detailed description of the invention
Below in conjunction with an embodiment, tire curing bladder forming method provided by the invention is described in detail.
Embodiment
The tire curing bladder forming method of the present embodiment, realize by the following method: control on capsule die, counterdie matched moulds to a certain extent time stop matched moulds, at this moment upper, an enclosed feed compartment is formed between counterdie, this feed compartment is connected with die cavity by annular runner, by vacuum extractor, the air in die cavity is all taken away simultaneously, die cavity is made to form certain vacuum, then with nozzle, sizing material is injected into feed compartment, injection volume controls by control system, injection terminates, pressurization, upper, counterdie compresses, sizing material is expressed in die cavity simultaneously, after mould compresses completely, cast gate and vacuumize mouth and blocked by template, die cavity is made to form a closed system, mould is opened after sulfuration terminates, capsule first departs from patrix under the compressed air effect be blown into, then lower tray jack-up, capsule is deviate from.
Claims (1)
