Abstract
Disclosed is a positioning device of a radiator molding box. Two upper holes, two lower holes and two positioning bolts are respectively arranged on the upper ends and the lower ends of an upper box and a lower box. An upper positioning sleeve and a lower positioning sleeve are arranged inside the upper hole and the lower hole of the upper box separately. A strip-shaped hole and a circular hole are separately arranged on the upper positioning sleeve and the lower positioning sleeve of the upper box. One end of a positioning bolt is circular and the other end is flat circular. The circular end of the positioning bolt is inserted into the upper hole of the lower box and is fixed by a locknut. The flat circular end of the positioning bolt is inserted into the strip-shaped hole of the upper positioning sleeve of the upper box when the moulds are assembled. The two ends of the other positioning bolt are all circular. One end of the positioning bolt is inserted into the lower hole of the lower flask and is fixed by a nut. The other end of the positioning bolt is inserted into the circular hole of the lower positioning sleeve of the upper box making the center stationary when the moulds are assembled. The utility model can position accurately and the yield rate of radiator casting is increased. The wall thickness of the radiators becomes even and the intensity of the radiators is enhanced not to be deformed easily making the core size of the casting become standard.
Description
Technical field
The utility model relates to the core casting field, particularly relates to a kind of positioner of radiator molding flask of improved difficult generation distortion.
Background technology
See also shown in Figure 1, existing sandbox positioner is that the two ends up and down of sand mold 2 under last sand mold 1 reaches are respectively equipped with positioning round orifice 11,21, in positioning round orifice 11,21, be inlaid with positioning sleeve 12,22, pin 3 inserts respectively in the hole 121,221 of positioning sleeve, can sand mold 1 and following sand mold 2 location will be gone up, wear and tear through the long-time back positioning sleeve 12,22 that uses, positioning sleeve can be dismantled, change.Molding flask generally can only be cast a slice radiator.
Sandbox is expanded by heating in use, the centre-to-centre spacing size of upper and lower positioning round orifice 11,21 is changed, make upper and lower sandbox 1,2 and upper and lower model produce dislocation, alignment pin can't insert, therefore must design the hole of positioning sleeve bigger, the gap between locating hole and the positioning sleeve is increased, produce dislocation when the consequence of Chan Shenging is cope 1 and drag box 2 matched moulds like this, make the radiator wall unevenness even, increase percent defective.
This shows that above-mentioned existing sandbox still has many defectives, and the assistant officer waits to be improved.
Because the defective that above-mentioned existing sandbox exists, the design people is actively studied innovation, through constantly studying, designing based on abundant practical experience and professional knowledge, and after studying sample and improvement repeatedly, create the utility model that has practical value finally.
The utility model content
Technical problem underlying to be solved in the utility model is, overcome the defective that existing sandbox exists, and provide a kind of positioner of radiator molding flask of new structure, it makes the accurate positioning of upper and lower sandbox, improve the yield rate of casting radiator, make the wall thickness of radiator more even, the intensity that increases radiator makes it be difficult for producing distortion, making the core size standard that casts out, and reduces the percent defective of casting.
The utility model solves its technical problem underlying and realizes by the following technical solutions.Positioner according to the radiator molding flask that the utility model proposes, its upper/lower terminal at upper and lower sandbox is respectively equipped with upper and lower hole and alignment pin, positioning sleeve on wherein on cope, being provided with in the hole, in the following hole of cope, be provided with positioning sleeve down, last positioning sleeve is provided with elongated hole, and following positioning sleeve is provided with circular port.
The utility model solves its technical problem and can also adopt following technical measures further to realize.
The positioner of aforesaid radiator molding flask, wherein said alignment pin, one end are round, the other end is oblate type, the circular portion of alignment pin inserts in the last hole of drag box, is fixed with locknut, and the oblate type of alignment pin partly inserts in the long shape hole of last positioning sleeve of cope.
The positioner of aforesaid radiator molding flask, the two ends of wherein said alignment pin are circle, an end of alignment pin are inserted in the hole of lower end of drag box, are fixed with nut, and the other end of alignment pin inserts in the circular port of following positioning sleeve of cope.
The positioner of aforesaid radiator molding flask, a wherein said upper and lower sandbox design has the structure of two radiators.
The utility model compared with prior art has tangible advantage and beneficial effect.By above technical scheme as can be known, the positioner of the utility model radiator molding flask, can make the location of upper and lower sandbox more accurate, improve the yield rate of casting radiator, make the wall thickness of radiator more even, the intensity that increases radiator makes it be difficult for producing distortion, making the core size standard that casts out, and reduces the percent defective of casting.
In sum, the positioner of the utility model radiator molding flask, it is had large improvement technically, and produced handy and practical effect, and have the effect of enhancement really, thus be suitable for practicality more, really be a new and innovative, progressive, practical new design.
The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
