Description
Technical field
The present invention relates to a kind of pipeline mould, more particularly to a kind of mould of prefabricated discharge duct.
Background technology
Flue, for excluding flue gas or the piping articles of toilet foul smell caused by the cooking activity of kitchen, also referred to as exhausting duct,
Ventilating duct, house exhaust passage, residence chimney neck are house kitchen, the chief component of toilet common exhaust duct system.
Existing discharge duct needs to open up through hole in the side wall of pipeline, to be connected with each family, realize flue gas or
The discharge of foul smell, discharge duct are thin-walled square cement pipelines, non-circular component, wall thickness 1.5cm, also added with iron wire in thin-walled
It is very inconvenient when opening up through hole Deng reinforcement, discharge duct is easily damaged, and then the bulk strength of discharge duct is influenceed,
And the shape of the through hole opened up is also irregular, the installation of subsequent parts is not easy to.
Discharge duct is thin-walled square cement pipeline, non-circular component, wall thickness 1.5cm, also added with iron wire etc. in thin-walled
Reinforcement, traditional approach can not complete the processing of discharge duct, for example, squash type, drawing and pulling type or it is centrifugal etc. can not the row of completion
The processing of feed channel.
Manual processing low production efficiency, the quality of each pipeline it is difficult to ensure that, processed by mould, mould can not be pull
Formula mould, can not be that hinge-type is installed, boss, cylinder or the single core rod of setting on template inwall, in form removal,
It must be internal model, external mold while translate unlatching, it is small that external mold parallel-moving type opens relative difficulty, but internal model is torn open using inside contraction type
Mould, because inner space is smaller, while to contract, difficulty is larger, and discharge duct length is generally several meters, and length is larger, wall
Thick relatively thin, inwardly contraction technology difficulty is too big simultaneously for internal model, it is difficult to realizes.
Boss or cylinder on template inwall is in casting process, in boss or cylinder insertion cement pipe fitting, after pouring not
Quick detachable, internal model can only be by above-mentioned contract formula form removal, and external mold uses parallel-moving type form removal, and form removal difficulty is big；In order to reduce
Form removal difficulty, releasing agent is set on boss or cylinder, still, the setting of releasing agent can influence the solidification of pipe fitting again, reduce pipe
The intensity of part, destroy the integrality of pipe fitting.
The content of the invention
