The invention discloses a mixed child-mother core assembly molding technology. A 3D printing molding technology and a sand mixing molding technology are combined, a part which is close to a product part having a plurality of structural features adopts 3D printing, and the other parts which have less structural features adopt the traditional sand mixing molding technology method, therefore an assembled sand mold which works through cooperative using of a mother core and a child core is formed. Based on the advantages of an original 3D printing molding technology, a traditional sand mixer production technology is introduced, the two molding technologies are combined with each other, further the cost of raw materials and the equipment investment cost are lowered, and meanwhile, child-mother separated core combination is conducted on a sand molding part which is brought out of a casting and the mold thickness which is brought out of a casting system and improves the strength so as to widen thinking for later multi-technology combination; the number of castings in a single sand box is increased, the sand box utilization ratio and the production efficiency are improved, the dependence on manual work is reduced at the same time, the cost of 3D printing raw materials and the depreciation of the equipment are reduced, and meanwhile, waste of molten iron is avoided, and the purposes of cost reduction and efficiency improvement are achieved.

A manufacturing method for a composite light filling component comprises the steps as follows: prefabricating a light internal mold; buckling the light internal mold; fixing the light internal mold; making a mixture of cement, mortar and glue; performing surface pretreatment, that is, spreading the mixture of the cement, the mortar and the glue, which is stirred well and in a semifluid state, onto the upper surface of the light internal mold; wrapping the light internal mold with a fiberglass mesh; performing surface treatment, that is, spreading the mixture of cement, mortar and glue, which is in the semifluid state, onto the lower surface and the peripheral side surface of the light internal mold to cover the fiberglass mesh; performing curing, that is, turning over the light internal mold after the mixture of the cement, the mortar and the glue on the lower surface is solidified and cured, and finally enabling the mixture of the cement, the mortar and the glue to form a hard inorganic composite layer on the outer surface of the light internal mold. The manufacturing method for the composite light filling component, provided by the invention, is simple, fast and reasonable in technological process; the composite light filling component manufactured according to the manufacturing method is reasonable in product structure, convenient for production and transportation and convenient and fast in construction.

The invention discloses a movable fixed base monorail hydraulic pipeline cutting device. Including: ordinary hydraulic pipe cutting machine system, intelligent wiring system for building fire protection pipelines, mortise joint movable guide rail and guide rail bottom support system, pipe cutting machine data reception and automatic movement and power system, two-dimensional code and fire protection logo spraying system. The present invention takes an ordinary hydraulic pipe cutting machine as the main body and is equipped with an intelligent wiring system for fire-fighting pipes in buildings. It can automatically obtain the pipe length data from the electronic drawings of the construction project to automatically find the cutting position for intelligent cutting of the pipes, reducing manual dependence. Labor costs can be saved, and the building information model can also be used to identify the work synchronously, automatically generate the identity information of the pipelines at each installation site, and use the two-dimensional code and the fire-fighting marking spraying system for marking to improve the efficiency of subsequent pipeline assembly.
