Fig. 2 is that overall structure of the present utility model is by A-A cutaway view among Fig. 1.

Fig. 3 is that overall structure of the present utility model is by B-B cutaway view among Fig. 2.

Among Fig. 1～Fig. 3, solidify the hinge (1) of gate, solidify gate plate (2), curing machine main body (3) is solidified gate button clamping plate (4), core box mould housing (5), core box mould entity (6), core (7), triethylamine airflow direction (8), the venting plug of core box (9), core box cavity (10), connect triethylamine tube inlet (11), leg (12) connects flue gas leading outlet (13).

The specific embodiment

Examples of implementation of the present utility model are such: with reference to accompanying drawing 1～Fig. 3, the utility model is mainly used in rapid shaping, craft and mechanically actuated and all can.The special-shaped complicated part of mould all can, the mold materials available metal also can use wooden model, plastic foil making.At first press accompanying drawing and make a curing casing; The curing machine comprises curing machine main body, leg, hinge, door-plate, knocker clamping plate, core box mould housing, core box mould entity, core, core box venting plug, connects compositions such as triethylamine pipe, outlet port.Curing machine main body (1) is independent active box, and support is arranged at the bottom, movable moving.Curing machine main body (1) top drilling is equipped with and connects triethylamine pipe (11).Triethylamine pipe (11) communicates with inner chamber (10).Bottom opening is installed exhaust emission tube (13).With core box mould entity (6), core (7) communicates, the mouth of pipe of exhaust emission tube (13) leads at core box entity (6) to solidifying between machine main body (3) the base plate face, between core box entity bottom surface and curing machine main body (3) the base plate face space is at interval arranged, the inside of core box mould housing (5) is core box mould entity (6), mould entity (6) has more than one hole more than one venting plug (9) is installed, mould entity (6) is moulding core (7) to the frame that encloses between the housing (5), and core (7) end face has the triethylamine gas that blows from pipe (11).There is the unit of cold-box core blower that the triethylamine generator is all arranged, or buys a triethylamine generator for using; Bottom, core chamber on the casting core mould of producing increases exhaust dress venting plug (9).The core box mold bottom is from the about 10mm of frame (5) bed hedgehopping.Solidify casing and triethylamine generator and connect, connect with waste gas cleaning system, like this, cold core sand manual core making solidifies machine just have been carried out.Secondly, use the coremaking of cold core sand, back-up sand on core box.The 3rd, the core box of filling in core sand is delivered in the curing machine: open that door-plate is put into curing machine inner chamber from the doorway and be that the plane is placed and to be closed locking and solidify gate on request, start the triethylamine generator, in the curing machine, supply gas, solidify core, waste gas is discharged, in the cleaning system discharged air.The 4th, open the curing gate, take out core box.Molding is come out core from the core box mould, finished the overall process of core sand manual core making like this.Use cold core sand manual core making curing machine to note: close the door after putting into upper hinge and sealed container door are blown in the core sand that triethylamine gas directly blows to core box entity core from air inlet pipe.Waste gas is then got rid of from exhaust outlet.Waste gas discharges through cleaning system.Can make various molding sand and the complicated core of abnormity like this.Its precision height is difficult for breaking, the efficient height, and labour intensity is low, is a kind of important breakthrough of manual core making technology, and the exemplar manufacturing is quick, and mould is simple, and cost is low, available wooden model, also available plastics, aluminum component, ironware molding.Coremaking precision height, the same with cold-box core blower coremaking dimensional accuracy, core is indeformable, and is very with practical value to the foundry goods that exemplar is manufactured experimently and monthly output is not high.Be that a kind of desirable cold-box manual core making solidifies machine.
