Abstract

The utility model relates to a casting compound mould with locating hole board, a sole plate of which is compounded by a wood sample plate and a hard locating hole board. The locating hole board is used for mechanical locating, and a core point is clamped in the hole board. The utility model has the advantages of accurate core point locating, human error eliminating, easy manufacture and assembly, etc. The compound mould can achieve that the locating error of a core point is not bigger than 0.5 mm.

Description

Casting compound mould with locating hloe board

The utility model relates to a kind of compound apperance of the casting of locating orifice plate that has, be specially adapted on the apperance main body to install vertical, dimensional requirement is accurate, the technological requirement of the intensive core print of arranging.Because this apperance fixedly taking special way on the core print, so the sand mold of routing up with it determines that the position of core is accurately firm.

In casting field; run into through regular meeting that gather in the vertical hole that resembles the blast funnace hot blast stove porous fire grate, the accurate heavy castings of position, hole dimensional requirement; when this member of casting, take which kind of core location measure, the quality that how to guarantee foundry goods is people's question of common concern always.During cast construction, need at first make sand mold, place core on the position by the object requirement accurately in sand mold again, whether the core location dimension accurately will directly affect the quality of foundry goods.Because core generally all adopts embedding inlay technique to fix, so whether accurate its location dimension concave point location with sand mold be directly related.And sand mold is routed up by apperance, and apperance is the key factor that influences casting quality thus.

Desire embeds in the sand mold core to realize the accurate in locating purpose, the concave point position that will require sand mold accurately, suitable size, that is to say that the core print installation dimension must be accurately firmly.Before the utility model was made, conventional core print installation method was: put core print on the wooden model of level, with wood screw it has been clenched and twist the jail, generally speaking, the process of putting and clench of core print is undertaken by manual operations.Because the central point of core print is aimed at the anchor point on the model is difficult, the difference of each point hardness so the tolerance of core print location is bigger, is difficult to satisfy the requirement of degree of precision to the influence of screw carry on the wooden in addition model.Salient point core print position on the apperance is exactly the concave point of sand mold, so the difference of core print position will be brought the inaccurate of core location.At above-mentioned situation, the utility model proposes a kind of compound apperance of casting with the location orifice plate, solved the problems referred to above preferably.

Of the present utility modelly have the compound apperance of the casting of locating orifice plate as shown in the figure, form by wooden model (1), hard location orifice plate (2), wood screw (3), hard core print (4).As substrate, hard location orifice plate (2) is the same core print size that forms after machining, the orifice plate of installation site unanimity to this compound apperance with wooden model (1).During assembling, earlier orifice plate is stacked on the wooden model (1), again hard core print (4) is embedded in the hard location orifice plate (2), use wood screw (3) that the three is clenched firmly at last again.Because hard core print (4) embeds in the location orifice plate (2), relied on the location, hole that is machined on the location orifice plate (2), so eliminated manual operations and factors such as wooden model nonhomogeneous hardness to the core print location influence, thereby realized the accurately purpose of location of core print.Among the embodiment, adopt the location orifice plate that has of the present utility model to cast compound apperance, the alignment tolerance that its core print is installed is no more than 0.5 millimeter.

Claims

1, a kind of compound apperance of the casting of locating orifice plate that has is made up of wooden model (1), hard location orifice plate (2), wood screw (3), hard core print (4), it is characterized in that hard core print (4) embeds in the hard location orifice plate (2).

2, the compound apperance of casting according to claim 1 is characterized in that wooden model (1) respectively and usefulness wood screw (3) stickfast between hard location orifice plate (2) and hard core print (4).
