Description
Technical field
The utility model relates to molten alloy casting field, is specifically related to a kind of sand core casting die.
Background technology
Sand mold casting refers to the castmethod producing foundry goods in sand mold. Steel, iron and most of non-ferrous alloy casting all can obtain with sand mould casting method. The molding material used due to sand mold casting is cheap and easy to get, and Casting mold manufacturing is easy, to the single piece production of foundry goods, produces by batch and produces in a large number and all can adapt to, for a long time, is the basic technique in Foundry Production always. Sand mold casting be that the foundry goods of the most popular and most simple types has adopted several centuries. Wherein casting mould refers to the structural shape in order to obtain part, makes the structural shape of part in advance with other easily shaping materials, and then puts into mould in sand mold, so just defining the core of a cavity the same with part scantlings of the structure in sand mold.
During casting, in order to form complete die cavity, it is necessary to upper and lower core is closed mould together, in order to ensure that upper and lower core closes the accurate of mould, usually in casting mould, all can be provided with locating mechanism, and there is strict requirement the position of locating mechanism to ensure the accurate of upper and lower core conjunction mould. And when the core needing casting different, the position of locating mechanism can along with the dimensional change of different core. In existing technology, in order to guarantee the accuracy of locating mechanism, locating mechanism is all be fixed in casting mould, different cores is made to have different casting moulds, form the imagination of a core casting mould, when the kind of product is a lot of time, adopt this kind of fixing locating mechanism then can produce very big manufacturing cost.
Practical novel content
During the locating mechanism that the utility model adopts fix to solve, when the kind of product is a lot of time, required casting mould also increases the present situation causing manufacturing cost to increase thereupon, and the purpose of this utility model is to provide the moveable sand core casting die of locating mechanism.
The utility model offer base case is: sand core casting die, locating mechanism when comprising the diaphragm capsule for loading molding sand and close mould for core, described diaphragm capsule comprises the base plate supporting molding sand and limits the sidewall of molding sand, described sidewall is fixed on described base plate, and described locating mechanism comprises steady brace, wherein, described locating mechanism is mobily connected on described base plate, it is provided with interlayer in described base plate, in described interlayer, it is placed with magnet, in described steady brace, be provided with magnet block.
The principle of work of base case: the structural shape of the part cast as required, the master mold of the structural shape of part is made in advance with other easily shaping metallic substance, master mold is placed in diaphragm capsule, the position of locating mechanism on base plate is measured in position according to master mold, again steady brace is placed on base plate, owing to being provided with magnet interlayer in base plate, after steady brace is placed on base plate, magnet block in steady brace and the magnet in base plate interact and make steady brace be fixed on base plate, pin to be positioned is fixed after well, fills molding sand in diaphragm capsule.
The useful effect of base case is: compare locating mechanism fixing in existing casting mould, the interaction of magnet is adopted to be set to moveable locating mechanism, the size of the mould that can cast as required adjusts locating mechanism accordingly, so that casting mould can be reused, avoid the present situation of a core mould.
Preferred version one: based on scheme preferred, described steady brace is provided with thread end, the threaded hole that described base plate is provided with described thread end adapts; Useful effect: by coordinating of the thread end on steady brace and the threaded hole on base plate, steady brace is made firmly to be positioned on base plate, avoid when filling molding sand owing to molding sand makes steady brace produce displacement to the reactive force of steady brace is excessive, thus ensure that the position of positioning hole on obtained core is accurate, it is ensured that accurate when core closes mould.
Preferred version two: based on scheme again one preferably, described sidewall is connected with reinforcing bar bar; Useful effect: when filling molding sand, in order to guarantee the phenomenon that the core obtained does not occur loosening, it is necessary to molding sand is carried out compacting, then diaphragm capsule can be produced a very big reactive force by molding sand, sets up reinforcing bar bar on sidewall, thus adds the firm property of diaphragm capsule.
Preferred version three: based on scheme again one preferably, described sidewall is provided with venting hole; Useful effect: set up venting hole on sidewall, it is possible to the gas in molding sand is discharged timely, it is possible to make molding sand obtain compacting to a greater extent, increases the hardness of obtained core.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
