Description
Technical Field
The invention relates to the technical field of casting sand boxes, in particular to an assembly adjustable casting sand box for sand casting.
Background
Sand casting is a casting method for producing castings in sand molds, steel, iron and most nonferrous alloy castings can be obtained by the sand casting method, the basic raw materials for manufacturing the sand molds are casting sand and sand binders, sand casting is always a basic process in casting production, sand boxes are fixing devices for fixing casting molds in casting production and are used for fixing sand molds after tamping, in practical application, parts are required to be molded into patterns, the patterns are placed into the sand boxes, sand is filled into the casting molds, and casting is performed after casting the respective casting molds.
Casting is a metal hot working process which is relatively early mastered by human beings, and is a method for obtaining a part or a blank by casting liquid metal into a casting cavity which is suitable for the shape of the part and cooling and solidifying the liquid metal, wherein sand casting is convenient to manufacture because materials are cheap and easy to obtain, and is suitable for single-piece production, batch production and mass production of castings, and is a basic process in casting production for a long time, and sand casting is carried out at present by using a sand box frequently.
The precoated sand mold casting is characterized in that high-quality carefully chosen natural sand is adopted as a sand base, a resin coating system with special performance and an optimal process technology are adopted, the perfect combination in the aspects of normal temperature performance, high temperature performance, collapsibility, fluidity, casting surface roughness and the like is striven for according to the technical requirements of different users, and the precoated sand mold casting is widely applied to industries such as automobile engines, diesel engines, hydraulic parts and the like.
Chinese patent literature (CN 112191812 a) discloses an adjustable casting flask for sand casting, which in the specification proposes "sand casting refers to a casting method for producing cast parts in a sand mold, and steel and most nonferrous alloy cast parts are available in sand casting methods; sand casting needs to use the sand box, but current sand box often is direct welded frame, and when taking out the foundry goods, often because of molding sand compaction is effectual, so lead to the foundry goods to take out comparatively laborious, the operation is comparatively inconvenient. The utility model provides a "simultaneously, through first U-shaped frame, the second U-shaped frame, fixed panel, the second pivoted plate, first pivoted plate and the sand box of connecting slat concatenation assembly frame shape, can be at the inside compaction molding sand of sand box, be used for processing foundry goods, carry out the joint to the link plate through the locking piece, realize locking the link plate, thereby realize carrying out locking connection with second pivoted plate and second U-shaped frame, when needing to take out the foundry goods after the casting, the operation locking piece separates with the link plate, release the locking of first pivoted plate and second pivoted plate, then shift forward first U-shaped frame, first U-shaped frame moves forward can open the opening of the front and back portion of sand box, be convenient for shift out of molding sand, make the whole by the compaction become lax, thereby be convenient for take out the foundry goods, the same reason can be with second U-shaped frame backward movement, increase the opening size of sand box, further be convenient for the foundry goods take out. However, the problem of low demolding efficiency, which is that the air contained in the molten metal cannot be effectively treated in the actual use process, is that the following problems remain in the apparatus described in the comparative case with the existing casting flask and the applied case:
1. when a workpiece is machined, a casting mold is required to be placed in a sand box, then a proper amount of natural sand is placed in the sand box for compaction, a metal solution is injected into the mold for sand casting, the casting is taken out after the casting is cooled, however, after the metal solution is poured into the casting mold, the metal solution is in a high-temperature state, air easily enters the metal solution in the pouring process, so that bubbles exist in the machined workpiece, the quality of the workpiece is affected, the sand in the sand box is difficult to clean completely when the sand base in the sand box is cleaned, and the follow-up use of the sand box is affected.
2. When clearing up the sand box, at present dismantle the back to its inside to the sand box at most, however in the in-service use's in-process, dismantlement and cause sand box connection and base to appear not hard up many times, lead to causing the sand box to fix unstably at the in-process of follow-up use for there is the clearance between the sand box faying surface, leads to the air to circulate in its inside, leads to the inside molten metal rapid cooling's of sand box phenomenon to take place.
