Smoke-air duct shocking casting machine

Abstract

The invention relates to a smoke-air duct shocking casting machine for buildings. The machine comprises a machine seat, an upper machine frame, an outer mold mechanism, an inner mold mechanism and a flat shocking pump, wherein the upper machine frame is arranged on the top surface of the machine seat; the shocking pump is arranged on the bottom of the upper machine frame; the outer mold mechanismcomprises two outer mold side plates and an outer mold bottom plate which form a smoke-air duct outer wall mold; the inner mold mechanism comprises a top mold plate, a bottom mold plate, two upper side mold plates and two lower side mold plate which form a smoke-air duct inner wall mold; and the shrinkage of the inner mold is realized by threads. By the smoke-air duct shocking casting machine, 20segments of smoke-air ducts can be produced within one working day, and the efficiency is higher; the produced smoke-air duct product is high in precision and meets the national standards; and the finished product has smooth internal and external faces and no edge fin, so that the problems of low production efficiency and unstable product quality existing in the prior smoke-air duct are solved. The casting machine is suitably used for producing various smoke-air ducts in different lengths and thicknesses.

Description

technical field [0001] The invention relates to a device for producing flue gas ducts for buildings. Background technique [0002] At present, the production of the flue gas duct is mainly performed by purely manual models. The production method of the flue gas duct as described in Chinese Patent No. 01140598 is to make the four panels forming the flue gas duct in blocks, and then fix them and demould them after curing. The method has a long production cycle and low efficiency. Another example is that the Chinese patent CN02264227.7 of semi-manual operation discloses a kind of flue gas duct mould, including bottom plate, side plate and sealing door etc., has practicability, but still be manual operation when producing flue gas duct with this mould, and this It is just a mold, which cannot achieve efficient production. The cost of mold production is high and the production efficiency is low. Contents of the invention [0003] In order to improve production efficiency and ...
