Abstract
The invention discloses a device for a hot core box plug-in water-cooling sandblasting nozzle. A structure of the device lies in that a side wall of a sand retention cap is provided with a cross-shaped through hole; and a sandblasting pipe body is composed of a blasting pipe inner cavity and a blasting pipe outer cavity. The blasting pipe body passes through a cooling plate; the blasting pipe outer cavity is communicated with a cooling plate water channel; the sand retention cap and the outer wall of the blasting pipe outer cavity are provided with flange interfaces; the sand retention cap, the cooling plate and the sand blasting pipe body are fixed together through bolts and the flange interfaces; seal pads are arranged between the sand retention cap and the cooling plate and between the cooling plate and the sand blasting pipe body; the lower end of the blasting pipe inner cavity is provided with a blanking cap; a blasting head and the bottom of the sandblasting pipe body are fastened in a thread manner; and a nozzle seal cartridge is tightly buckled with a shoulder of a nozzle head flange. The device can be used for making cores of various hot core boxes; the blasted sand cores have smooth surfaces; the nozzle parts are in not need of spackling, thereby reducing sand hole waste products and saving cost of resin sand. Due to a split structure of the blasting head, only the nozzle seal cartridge is dismantled during maintenance.
Description
Technical field
The invention belongs to mechanical sand casting technology, be specifically related to a kind of device of penetrating sand mouth for hot box inserted water cooling.
Background technology
At present the complicated inner cavity of the gray iron of engine is not processed mostly, completes the manufacture of gray iron by producing smooth surface, the superior core of size.Current people are more and more higher to the performance requirement of engine, and the precision of gray iron foundry goods is the most important thing that ensures engine quality.In sand casting process, make the full cored-up mould of the many employings of complex-shaped foundry goods.Engine building, for the equipment of foundry goods coremaking, mainly contains two kinds of hot box core-making machine and cold-box core making machines at present.In hot box process process, the core that traditional flat fire sand mouth is made must leave one section of nozzle plug on core.After plug cleaning, pit will be left in this position, then must repair with patching material, with the geometry that ensures that its position is complete.So just make core manufacture craft become comparatively complicated, except increasing labour intensity, also reduced production efficiency.
Summary of the invention
In view of the defect of traditional flat fire sand mouth coremaking, the object of the invention is, a kind of device of penetrating sand mouth for hot box inserted water cooling is proposed.
For realizing the technical scheme that object of the present invention adopts be: hot box inserted water cooling blast nozzle, on sand block cap sidewall, have cross-hole, blast tube body is made up of jet pipe inner chamber and jet pipe exocoel.Spout body is through coldplate, and jet pipe exocoel communicates with coldplate water channel, and the outer wall of sand block cap and jet pipe exocoel is equipped with flange-interface, and sand block cap, coldplate and blast tube body are fixed as one by bolt and flange-interface.Between sand block cap and coldplate and between coldplate and blast tube body, be equipped with sealing gasket.Lower end at jet pipe inner chamber is provided with blanking cover, and injector head and blast tube body bottom are fastening by thread forms, and nozzle sealing shroud and nozzle head flange shoulder interlock fastening.
Injector head is referred to as to penetrate Sha Zui in industry.The lower surface of blanking cover is concave shaped, and penetrating a upper surface for interior straight length jet pipe is convex-shaped, the gap forming between indent and epirelief, and its effect is to make precoated sand enter injector head.The effect of sand block cap is in sand blasting unit, to carry out secondary sand block, and the aperture on sand block cap sidewall can be controlled sand (while thering is no pressure) can not enter jet pipe inner chamber, and while penetrating the pressure disconnection of sand, the sand of blast tube inner chamber can stop flowing immediately.The effect of blanking cover is that sand can not flow out in the situation that there is no blast.
The beneficial effect of feature of the present invention and generation is: inserted water cooling is penetrated Sha Zui and is applied in various hot box process; Penetrate the not only smooth surface of core of making, and nozzle position smears without repairing, both reduced foundry goods sand holes waste product, reduced core and repair and smear labour intensity, saved again the cost of peritonaeum sand.Because injector head is Split type structure, so only need disassemble nozzle sealing shroud while maintenance.

detailed description of the invention
Referring to each accompanying drawing and by embodiment, theory and structure of the present invention is further described.
Hot box inserted water cooling blast nozzle, has sand block cap, blast tube body, coldplate, sealing gasket, blanking cover, nozzle sealing shroud and sprays first-class.Its structure is: the sidewall of sand block cap 1 has cross-hole, and blast tube body is made up of jet pipe inner chamber 2 and jet pipe exocoel 3, and spout body is through coldplate 4, and jet pipe exocoel communicates with coldplate water channel, and the outer wall of sand block cap and jet pipe exocoel is equipped with flange-interface.Sand block cap, coldplate and blast tube body are fixed as one by bolt and flange-interface.Between sand block cap and coldplate and between coldplate and blast tube body, be equipped with sealing gasket 5, be provided with blanking cover 6 in the lower end of jet pipe inner chamber, injector head 7 is fastening by thread forms with blast tube body bottom, and nozzle sealing shroud 8 interlocks fastening with nozzle head flange shoulder.
Between jet pipe inner chamber and jet pipe exocoel, be provided with spiral water channel.The lower surface of blanking cover is concave shaped; The top in straight tube chamber is convex-shaped in injector head, and convex both sides are provided with 20 °～25 ° domatic; The outside conical surface angle of injector head is 80 °～90 °.Because being rubber bodies, makes by nozzle sealing shroud, so directly interlock fastening with nozzle head flange shoulder.Be drilled with at coldplate the water channel hole that diameter is 16～20mm, cooling for to injector head.
As embodiment, in coldplate, be drilled with the water channel hole that diameter is 18mm.The domatic angle [alpha] in convex both sides is 20 °; The outside conical surface angle beta of injector head is 87 °; On sand block cap sidewall, the diameter of cross-hole is 10mm.
Injector head is referred to as to penetrate Sha Zui in industry.When sand casting, multiple Sha Zui of penetrating are fitted together, the cooling circulating water in coldplate flows through the spiraled cavity of penetrating between the inside and outside chamber of sand mouth, jet nozzle is carried out cooling, prevents the obstruction of being heated of peritonaeum sand.Between sand block cap and coldplate and between coldplate and blast tube body, be equipped with sealing gasket, prevent that coldplate from leaking, and nozzle body lower end sealing gasket, can prevent that cooling water from passing through nozzle head and flowing into mould cavity simultaneously.
The cross-hole of precoated sand from sand block cap sidewall enters in the inner chamber of spout body, entering injector head from the gap between blanking cover and nozzle inner chamber.Sand is injected upper core box body along (top, straight tube chamber in injector head) injector head straight tube chamber.
