Abstract
The utility model discloses a kind of Novel sand-core core boxes, left core box and right core box including level die sinking, hollow cavity, the funnel shaped vibrations cylinder body penetrated Sha Kou and bottom and connected with the cavity connected with the cavity of upper end are formed when the left core box and the right core box molding, vibrations piston is equipped in the vibrations cylinder, the left core box of the cavity both sides and the inside of the right core box offer to be embedded in the embedding groove of chill.The Novel sand-core core box of the utility model, it is shaken by shaking piston, the vibrations for the coated sand being piled up in the cavity can be caused, so as to improve the degree of packing of resin coating sand wash and so that the degree of packing of the coated sand in the cavity everywhere is suitable, sand core quality is improved, production precision is high；The cooling down chill insertion of selectivity is capable of by the embedding groove, ensure that cooling effect, and the fixation of chill is simple and convenient, is easy to use.
Description
Technical field
The utility model is related to make core process equipment technical field more particularly to a kind of Novel sand-core core box.
Background technology
Core box is the technological equipment that coated sand is made to core.In general, the mode of sand is vertically penetrated than transverse direction
It is high to penetrate the quality of sand core made of the mode of sand, this is because the vertical mode for penetrating sand can make coated sand heap from the bottom up
Product, the degree of packing is higher, and nonetheless, the sand core of this degree of packing still cannot meet production needs, and corner on one point
Position easily generates gap, it is impossible to carry out accurate production；And the cooling of existing sand core core box is all in sand core core box mostly
Surface chill is shelved to realize, the cooling effect of this type of cooling is bad, and chill is not fixed easily, it is impossible to meet production
It needs.
The content of the invention
In view of this, the utility model provides a kind of Novel sand-core core box, disclosure satisfy that the demand of made with high precision, and has
There is good cooling effect.
The utility model is solved the above problems by following technological means：
The Novel sand-core core box of the utility model, left core box and right core box, the left core box and institute including level die sinking
State formed during the molding of right core box hollow cavity, upper end connect with the cavity it is funnel shaped penetrate Sha Kou and bottom and
The vibrations cylinder body of the cavity connection, the vibrations cylinder is interior to be equipped with vibrations piston, the left core box of the cavity both sides and institute
The inside for stating right core box offers to be embedded in the embedding groove of chill.
Preferably, the embedding groove has multiple, and the sides aligned parallel of multiple embedding grooves and the cavity is set.
Preferably, it is upper limit position when the vibrations piston starts and stops, when the vibrations piston is located at upper pole
During extreme position, the top of the vibrations piston is concordant with the bottom of the cavity.
The Novel sand-core core box of the utility model, is shaken by shaking piston, can be caused and is piled up in the cavity
Coated sand vibrations, so as to improve the degree of packing of resin coating sand wash and cause coated sand in the cavity
The degree of packing everywhere is suitable, improves sand core quality, and production precision is high；By the embedding groove be capable of selectivity by chill
Insertion is cooled down, and ensure that cooling effect, and the fixation of chill is simple and convenient, is easy to use.
Description of the drawings
Fig. 1 is the structure diagram of the Novel sand-core core box of the utility model.
Reference sign：Left core box -1, right core box -2, cavity -3, penetrate Sha Kou -4, vibrations cylinder body -5, vibrations piston -6,
Chill -7, embedding groove -8.
Specific embodiment
In the description of the utility model, it is to be understood that term " " center ", " on ", " under ", "front", "rear",
The orientation or position relationship of the instructions such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on attached drawing institutes
The orientation or position relationship shown is for only for ease of description the utility model and simplifies description rather than instruction or imply signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that this practicality
New limitation.
The utility model is described in detail below with reference to attached drawing：Novel sand-core core box described in the present embodiment, bag
Include the left core box 1 and right core box 2 of horizontal die sinking, the left core box 1 and the right core box 2 formed when molding hollow cavity 3, on
The funnel shaped vibrations cylinder body 5 penetrated sand mouth 4 and bottom and connected with the cavity 3 connected with the cavity 3 at end, it is described
It shakes and vibrations piston 6 is equipped in cylinder, the left core box 1 of 3 both sides of cavity and the inside of the right core box 2 offer and is used for
The embedding groove 8 of embedded chill 7.
Novel sand-core core box described in the present embodiment is shaken by shaking piston 6, can cause and be piled up in the cavity
The vibrations of coated sand in 3, so as to improve the degree of packing of resin coating sand wash and cause coated sand in the type
The degree of packing in chamber 3 everywhere is suitable, improves sand core quality, and production precision is high；Selectivity is capable of by the embedding groove 8
The insertion of chill 7 is cooled down, ensure that cooling effect, and the fixation of chill 7 is simple and convenient, is easy to use.
For the ease of using, cooling effect is improved, as being further improved for above-mentioned technical proposal, the embedding groove 8 has
It is multiple, and the sides aligned parallel of multiple embedding grooves 8 and the cavity 3 is set.
For the ease of using, further increase production precision, as being further improved for above-mentioned technical proposal, the shake
Piston 6 starts and is upper limit position when stopping, and when the vibrations piston 6 is located at upper limit position, the vibrations are lived
The top of plug 6 is concordant with the bottom of the cavity 3.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover among the right of the utility model.
