Description
Technical field
This utility model is related to cast iron unit technical field, more particularly to a kind of sandbox with loam core.
Background technology
Sandbox with loam core is referred to as cored-up mould for manufacturing foundry goods, and the formative method of cored-up mould is relatively simple,
Simply the several loam cores for having manufactured are placed in sandbox and are combined and are assembled, then carry out pouring molten iron carries out foundry goods system
Make.
In prior art during cored-up mould it is used to the sandbox with loam core referring to shown in accompanying drawing 5：What is manufactured is several
The combination of sand cake 5 is placed in a casing, and each sand cake 5 is stably erected in casing by self gravitation effect, then is passed through
The case lid closed above casing, 5 upper surface of sand cake push against the upper inwall in case lid and realize being clamped between casing and case lid,
Simultaneously the adjacent sand cake of length direction 5 contacts with each other but does not push against.
Into casing pouring molten iron and treat its solidification so that mold foundry goods.During injection molten iron, molten iron is filled in
In gap between loam core, as molten iron has certain flow velocity and mobility is larger, the effect of extruding is produced to loam core side wall
Power, when active force is more than the frictional force of inwall and tank floor on the upper and lower end face of loam core and case lid, just occurs that loam core goes out
The situation of existing displacement, ultimately causes the casting dimension for molding and changes.
Utility model content
The purpose of this utility model is to provide a kind of sandbox with loam core, by filling packing agent in filler intracavity, real
Mutually push against between existing sand cake, and then when molten iron is poured into, sand cake position does not change.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of sand with loam core
Case, including the casing and case lid that match；The cabinet wall has built loam core outer container, and the loam core outer container bottom is provided with molding

Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1：A kind of sandbox with loam core, as shown in figure 1, including the irony casing and case lid 3 that match, casing
Including under casing 1 and top box 2,1 top of under casing and 2 bottom of top box accordingly offer through hole, wear two by bolt and pass through
Bore a hole, and wear end and tightened using nut, some groups of bolt thread coupling nuts are set between under casing 1 and top box 2 so as to reality
Both fixations existing are detachably connected.
With reference to shown in Fig. 1 to 3, cabinet wall is built loam core outer container 4, and loam core outer container 4 is made up of uncured resin acid, not
Hardening resin acid includes vertical, sandstone and bonding agent.The bottom of loam core outer container 4 offers forming tank, and forming tank is used to mold
The bottom of foundry goods.The some sand cakes 5 of arrangement in casing, sand cake 5 are also made up of uncured resin acid, and sand cake 5 is erect and put
Put on the bottom surface of loam core outer container 4, and the side on 5 length direction of sand cake is arranged in conflict with 4 inwall of loam core outer container, mud
Core outer container 4 is offered with forming tank in a cast runner 51 for connecting setting, can be injected by a cast runner 51 into forming tank
Molten iron, the chamber formed by sand cake of different shapes 5 can mold entirety of the foundry goods in addition to bottom.
For between sand cake 5 and loam core outer container 4, connection is accomplished by：Directly with loam core outer container 4 in
Wall contradict for one piece of trapezoid block 8, trapezoid block 8 includes the limited block 81 positioned at both sides；Loam core outer container 4 accordingly opens up limited location
Groove 41, size of the stopper slot 41 slightly larger than limited block 81, after limited block 81 is placed in stopper slot 41, stopper slot 41 is to spacing
Block 81 is with the position-limiting action along casing length direction；Offer in perpendicular in the side of 4 inwall of contact loam core outer container of trapezoid block 8
The straight lateral channel 52 for arranging, for rectangle, which has a bottom surface 521 and two sides 522, the width of bottom surface 521 to lateral channel 52
Width of the degree more than side 522；Packing cavity is formed between lateral channel 52 and loam core outer container 4；Mud in the middle of loam core outer container 4
Pellet 5 is rectangle, and the side of the width of rectangle sand cake 5 is directly contacted with trapezoid block 8；Packing agent is filled to filler intracavity
6 and fill closely knit, packing agent 6 is also made up of uncured resin acid, as the packing agent of uncured resin acid has necessarily
Volume, extruding trapezoid block 8 and loam core outer container 4 especially applies the active force along casing length direction, therefore limits to sand cake 5
Position groove 41 allow trapezoid block 8 81 moving range of limited block in, trapezoid block 8 can to the rectangle sand cake 5 at middle part move so as to
Rectangle sand cake 5 is pushed against.
The side of 5 length direction of rectangle sand cake in the middle part of the present embodiment is built near lower surface simultaneously raised 53, projection
53 contact at adjacent rectangle sand cake 5, in order to prevent the inclination on 5 top of sand cake, while and adjacent two pieces of sand cakes 5 it
Between clamping have a metallic gasket 7, the fusing point of the fusing point of metallic gasket 7 less than foundry goods, i.e. metallic gasket 7 can be melted by molten iron.
Case lid 3 is a rectangle frame, and rectangle inframe has also built sand cake 5, corresponding to cast on the sand cake 5 in case lid 3
Runner 51 offers duct, case lid 3 is overturn 180 ° using driving and is closed on casing, the edge post 31 on case lid 3 is inserted
The position-limiting action of the 21 pairs of edge posts 31 in hole in edge hole 21 on casing, is inlayed, locking of the top box 2 to 3 peripheral direction of case lid is realized；
To duct and a cast runner 51 to molten iron is filled between loam core outer container 4 and sand cake 5, after waiting foundry goods molding, sandbox is dismantled
And break removing loam core outer container 4 into pieces and sand cake 5 obtains cast product.
Embodiment 2：A kind of sandbox with loam core, as shown in figure 4, lateral channel 52 is vertically opened in loam core outer container 4
Wall, sand cake 5 contradict 4 side of loam core outer container and fill out to be formed between the lateral channel 52 of burnishing surface, sand cake 5 and loam core outer container 4
Material chamber, can also realize applying active force to sand cake 5 to the uncured resin acid of filler intracavity filling so that in the longitudinal direction
Sand cake 5 mutually can push against.
With reference to above two scheme, it is preferred to use the scheme of embodiment 1, being primarily due to uncured resin acid can fill up
In lateral channel 52, the acid of the uncured resin that fills up to the bottom surface 521 i.e. active force of the applying of sand cake 5 of lateral channel 52 compared with
For uniform so that sand cake 5 is relatively stable when pushing against each other；And the resinic acid filled up is back to 52 bottom surface 521 of lateral channel
Side is that the applying active force of loam core outer container 4 is more uneven.
This specific embodiment is only which is not to restriction of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification for not having creative contribution after this specification is read as needed to the present embodiment, but
As long as all being protected by Patent Law in right of the present utility model.
