Abstract
The utility model provides an improved sand sliding hopper for a sand-mold molding machine. The sand sliding hopper comprises a sand sliding hopper body, and is improved in that a layer of outer casing is arranged on the outer side of the wall surface of the sand sliding hopper body, a partition board is arranged in space formed by the inner side of the outer casing and the outer side of the wallsurface of the sand sliding hopper body, so that the outer casing is connected and fixed with the sand sliding hopper body, a hot gas inlet and a cold gas outlet are formed on the outer casing body, the sand sliding hopper further comprises a vent pipe, one end of the vent pipe is connected with the hot gas inlet while the other end thereof is connected with a hot gas source, the hot gas enters the outer casing from the hot gas inlet and flows in the space formed by the inner side of the outer casing and the outer side of the wall surface of the sand sliding hopper body, the cold gas after cooled down is discharged from the cold gas outlet, and the temperature of the wall surface of the sand sliding hopper is increased due to hot gas flow, thereby increasing the temperature of the wall surface of the sand sliding hopper, decreasing the temperature difference between the wall surface of the sand sliding hopper and the external, effectively avoiding the problem that sand is stuck to theinner wall of the sand sliding hopper, reducing the shut-down accident, and improving the production efficiency.
Description
Technical field
The utility model relates to the sand mold moulding machine, relates in particular to a kind of improved sand mold moulding machine slide sand hopper.
Background technology
Existing sand mold moulding machine is provided with for sand belt, be used for to slipping the sand hopper transport of sand, enter the moulding main frame and penetrate and carry out moulding in the sand storehouse through slipping sand hopper by the sand of carrying for sand belt, this sand mold moulding machine is provided with vavuum pump at the core setter place, to pass through the negative-pressure adsorption sand mold, discharge through the air themperature rising of vavuum pump and by vacuum pump body, promptly vavuum pump is discharged the waste gas of heat.For sand belt when slipping in the sand hopper transport of sand; as shown in Figure 1; because the difference of slide sand hopper 1 inner wall temperature and environment temperature; sand 2 is bonded on slide sand hopper 1 internal face; cause slide sand hopper 1 inner product sand too much; cause for the stifled sand of sand belt, and then make the main frame overload and shut down, this phenomenon is especially serious in the winter time.
The utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that existing product exists; and provide a kind of improved sand mold moulding machine to slip sand hopper; add one deck overcoat in the slide sand hopper wall outside; be provided with a dividing plate between this outer casing inner wall and the slide sand hopper outside wall surface; overcoat and slide sand hopper outside wall surface are connected and fixed; and between overcoat inboard and slide sand hopper outside wall surface, form the space; this overcoat body is provided with hot air intake and cold air outlet; hot air intake connects breather pipe; this breather pipe other end is connected with the hot gas source; allow hot gas enter in the overcoat; flow in the space that between overcoat inboard and slide sand hopper outside wall surface, forms; hot gas cooling back cold air is discharged by cold air outlet; slip the sand hopper wall surface temperature owing to the hot gas that flows improves, thereby reduce to slip the sand hopper wall and the extraneous temperature difference, effectively avoid sand to be bonded at the problem of slide sand hopper inwall; reduce stopping accident, enhance productivity.
The purpose of this utility model is realized by following technical scheme.
The improved sand mold moulding machine slide of the utility model sand hopper comprises slide sand hopper body 1; Its improvements are, this slide sand hopper body 1 wall outside is provided with one deck overcoat 3, be provided with a dividing plate 4 in the space that these overcoat 3 inboards and the slide sand hopper body 1 wall outside form, overcoat 3 and slide sand hopper body 1 are connected and fixed, this overcoat body is provided with hot air intake 31 and cold air outlet 32; Also comprise a breather pipe 5, these breather pipe 5 one ends are connected with hot air intake 31, another termination hot gas source.
Aforesaid improved sand mold moulding machine slide sand hopper, the height of its median septum 4 is identical with the height of slide sand hopper body 1.
Aforesaid improved sand mold moulding machine slips sand hopper, wherein the hot air intake 31 that is provided with of overcoat body and cold air outlet 32 both sides that lay respectively at overcoat body and dividing plate 4 junctions.
The beneficial effect of the improved sand mold moulding machine slide of the utility model sand hopper; it adds one deck overcoat in the slide sand hopper wall outside; be provided with a dividing plate between this outer casing inner wall and the slide sand hopper outside wall surface; overcoat and slide sand hopper outside wall surface are connected and fixed; and between overcoat and slide sand hopper outside wall surface, form the space; this overcoat body is provided with hot air intake and cold air outlet; this hot air intake and cold air outlet lay respectively at the both sides of overcoat body and dividing plate junction; hot air intake connects a breather pipe; this breather pipe other end is connected with the hot gas source; allow hot gas enter in the overcoat; flow in the space that between overcoat inboard and slide sand hopper outside wall surface, forms; discharge from outlet then; because hot air intake and cold air outlet are the both sides that lay respectively at overcoat body and dividing plate junction; therefore enter in the overcoat hot gas can overcoat inboard with slip a mobile week in the space that form between the sand hopper outside wall surface; discharge from the cold air outlet of overcoat body again; thereby can make full use of the temperature of the heat raising slide sand hopper wall in the hot gas; reduce to slip the sand hopper wall and the extraneous temperature difference; effectively avoid sand to be bonded at the problem of slide sand hopper inwall; reduce stopping accident, enhance productivity.
