Abstract
The utility model belongs to a sand core box and particularly relates to a multivalve segment jacket frame type sand core box, which comprises a left half box body and a right half box body, wherein the left half box body and the right half box body are positioned by positioning pins and connected by bolts to form a box body; the multivalve segment jacket frame type sand core box also comprises an inner frame consisting of valve molds; the inner frame is sleeved with the box body; key slots matched with a positioning block and a wide positioning block are arranged on the inner frame and the box body respectively; the positioning block and the wide positioning block are fixed on the box body; and an external conical surface of the inner frame is matched with an inner conical surface of the box body. The utility model has the advantages of accurately positioning and improving the accuracy and the work efficiency by adopting a forming mode that an integral sand core is formed by combining multi-section sand core boxes instead of a forming mode that a plurality of sand cores are formed by independent sand core boxes and combined. With a multivalve structure, a certain quantity of movable blocks are integrated into a whole, the sand core box is convenient and rapid to assemble and open mold and is not easy to loosen.
Description
Technical field
The utility model belongs to a kind of core box, is specifically related to a kind of many lobes segmentation frame core box.
Background technology
Bigger for length, inner chamber has the rotary body foundry goods of longitudinal and transverse ribs, boss etc., the general at present cover frame core box that adopts, and as shown in Figure 1, inside casing is made of the loose piece of the some that has the projection profile, in the whole housing of packing into.Operation principle is by casting length design multistage core box, the moulding of every section core box independence, and the core with all core box moulding is combined into an integral body at last.Because the combination of core is with core core print location, so its location is coarse, accuracy is poor, and the combination core is wasted time and energy inefficiency.
Summary of the invention
Many lobes segmentation cover frame core box that the purpose of this utility model provides a kind of accurate positioning, accuracy is high and can increase work efficiency.
The utility model is to realize like this, a kind of many lobes segmentation cover frame core box, it comprises left half box body and right half box body, locate, connect to form box body by alignment pin between the two with bolt, comprise also by the lobe mould and form inside casing that inside casing and box body suit are respectively equipped with the keyway that cooperates with locating piece, wide locating piece on inside casing and the box body, locating piece, wide locating piece are fixed on the box body, and the inside casing male cone (strobilus masculinus) cooperates with the box body inner conical surface.
Wherein said box body, inside casing, locating piece, wide locating piece are metal material.
The utility model has the advantages that with multistage core box combination forming integral sand core, substituted with a plurality of cores of independent core box moulding, with the molding mode of core combination, accurate positioning has improved accuracy and operating efficiency again.By many lobes mode structure the loose piece of some is integrated into integral body, core box assembling, die sinking be convenient, fast, it is loosening to be difficult for.

Among the figure, 1 hypomere core box, 2 epimere core boxs, 3 inside casings, 4 locating pieces, 5 sunk screws, 6 box bodys, 7 wide locating pieces, 8 alignment pins, 9 bolts, 10 lobe moulds, 11 housings, 12 mold inserts, 13 straight pins, 14 screws, 15 left half box bodys, 16 right half box bodys, 17 loose pieces.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail:
As shown in Figures 2 and 3, a kind of many lobes segmentation cover frame core box comprises box body 6, inside casing 3, locating piece 4 and wide locating piece 7.Box body is divided into a left side, right two halves, a left side, right half box body 15, locate by alignment pin 8 between 16, connect with bolt 9, inside casing 3 is made up of a plurality of lobe moulds 10, with box body 6 suits, all have and locating piece 4 on inside casing 3 and the box body 6, the keyway that wide locating piece 7 cooperates, locating piece 4, wide locating piece 7 is fixed on the box body 6, inside casing 3 male cone (strobilus masculinus)s cooperate with box body 6 inner conical surfaces, by locating piece 4, wide locating piece 7 is determined rigging position, be assembled into hypomere core box 1 and epimere core box 2 so respectively, each section hypomere core box 1 and epimere core box 2 be along short transverse stack, between hypomere core box 1 and the epimere core box 2 with alignment pin 8, conical surface seam location.
Wherein said box body 6, inside casing 3, locating piece 4, wide locating piece 7 materials can adopt any metal material.
Described box body 6 is shaped as the revolving body of certain wall thickness, be divided into left and right two halves, interface is box body 6 die joints, inner chamber is a taper seat, conical surface symmetric position has two keyways that width does not wait, box body 6 upper surfaces have conical surface boss, and the lower surface has conical surface seam, and boss is not with in box body 6 upper surfaces of epimere.
Described inside casing 3 is a kind of many lobes mould 10 sub-assemblies, inside casing 3 is shaped as revolving body, be divided into a plurality of according to type projection distribution situation in the casting product, generally according to projection withdrawing pattern direction, be divided into 7～9 according to certain center of circle angle, inside casing 3 profiles are that taper seat cooperates with box body 6 inner chambers, male cone (strobilus masculinus) has two keyways, width and position are corresponding with keyway on the box body 6, inner chamber is consistent with type in the product of being cast, and is convenient processing, and lobe mould 10 is made up of housing 11 and mold insert 12, housing 11 is a revolving body, is connected housing 11 and mold insert 12 with straight pin 14 with screw 13.
Described locating piece 4, wide locating piece 7 usefulness sunk screws 5 are fixed in box body 6 keyways, and equipped with box body 6 and inside casing 3 keyways, length equates with the height of box body 6 and inside casing 3.
When using, the utility model earlier every section left and right half box body 15,16 is combined into box body 6 respectively, again the lobe mould 10 of correspondent section band keyway is put into box body 6 correspondence positions, then adjacent petals mould 10 is put into box body 6 successively, treating that the lobe mould is packed into finishes, with bolt 9 fastening left and right half box bodys 15,16, and with alignment pin 8 location.Hypomere core box 1 is put on the sand face, epimere core box 2 is put in the upper surface of hypomere core box 1, epimere core box 2 cooperates with the conical surface boss of hypomere core box 1 with seam makes two sections core boxs, 1,2 axle center consistent, and with alignment pin on the end face 8 location, prevent that two sections core boxs 1,2 from rotating around the center.If core box more than 2 sections, then according to this method, is seated all core boxs successively.After the assembling of multistage core box is finished, come into operation, carry out operations such as a sand, curing.In the time of die sinking, unclamp earlier epimere core box 2 bolt 9, take off alignment pin 8, open epimere core box 2 left and right half box bodys 15,16, according to the die sinking direction of delineation on the lobe mould 10, extract lobe mould 10 one by one, same quadrat method, open hypomere core box 1, extract lobe mould 10, realize the integral sand core moulding.
