Description

A kind of molding die of prefabricated discharge duct

Technical field

The utility model is related to a kind of pipeline molding die, more particularly to a kind of shaping mould of prefabricated discharge duct Tool.

Background technology

Flue, for excluding the piping articles of flue gas that kitchen cooking activity generates or toilet foul smell, also referred to as exhausting duct, Ventilating duct, house exhaust passage, residence chimney neck be house kitchen, toilet common exhaust duct system chief component.

Existing discharge duct needs open up through-hole on 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 Reinforcing ribs are waited, it is very inconvenient when opening up through-hole, discharge duct is easily damaged, and then influence the integral strength of discharge duct, And the shape of the through-hole opened up is also irregular, is not easy to the installation of subsequent parts.

Discharge duct is thin-walled square cement pipeline, non-circular component, wall thickness 1.5cm, also added with iron wire etc. in thin-walled Reinforcing rib, 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 mold, mold cannot be pull Formula mold can not be that hinge-type is installed, boss, cylinder or the individual mold core of setting on template inner wall, in form removal, Must be that internal model, external mold translate unlatching simultaneously, external mold parallel-moving type unlatching relative difficulty is small, but internal model is torn open using inside contraction type Mould, since 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 realize.

Boss or cylinder on template inner wall is in casting process, in boss or cylinder insertion cement pipe fitting, after pouring not Quick detachable, internal model can only use parallel-moving type form removal by above-mentioned contract formula form removal, external mold, and form removal difficulty is big；In order to reduce Form removal difficulty sets releasing agent on boss or cylinder, and still, the setting of releasing agent can influence the solidification of pipe fitting again, reduce pipe The intensity of part destroys the integrality of pipe fitting.
