Abstract
The utility model discloses a fastening device for a square casting mold, which is applied to fasten a square casting mold made by box molding during the casting process of nodular cast iron. The fastening device comprises two press plates and two pulling plates. The two press plates are positioned on the top flat surface and the bottom surface of a casting mold to be reinforced respectively; and the two ends of each press plate are exposed outside the two lateral surfaces of the casting mold to be reinforced and provided with elongated through-holes. Connecting holes are formed on the two sides of each elongated through-hole. Adjusting holes are formed on the pulling plates. The pulling plates pass through the two press plates via the elongated through-holes of the press plates, and the press plates and the pulling plates are fixedly connected together via pins which pass through the connecting holes on the two sides of each elongated through-hole of the press plates and the adjusting holes on the pulling plates. With the technical scheme, the fastening device effectively prevents the arching-up of the top of a sand box and the extension of a fastening bolt due to the internal stress produced by the graphite expansion during the consolidation of molten iron, and can stabilize the casting mold size, reduce casting defects and improve the mechanical performance of a casting.
Description
Technical field
The utility model relates to the Foundry Production technical field, and especially a kind of being applicable to carried out fastening bracing means to the square casting mold that adopts the box moulding gained when casting ductile cast iron casting.
Background technology
When casting industry is produced spheroidal graphite cast-iron, adopt the sandbox of steel plate welding to come moulding basically, use the bolted sandbox after the mould assembling, pour into a mould then.Because sandbox and bolt all are flexible steel matter, ductile cast iron casting is when the cast after coagulation, its inner graphitization expansion can produce huge internal stress, cause the top of sandbox to be arched upward and the elongation of fastening bolt, will cause the die cavity of casting mold to become big like this, casting dimension changes, not only casting weight increases, processing dimension is inaccurate, and can produce casting flaws such as shrinkage cavity, shrinkage porosite and underpriming, reduce the mechanical performance of foundry goods, particularly large-scale and heavy ductile cast iron casting, this phenomenon is more obvious, and consequence is also more serious.
The utility model content
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of bracing means of square casting mold is provided, it can prevent effectively that ductile cast iron casting is after cast, because arch upward in the top of the sandbox that the internal stress effect that graphite expansion produces when solidifying causes and the elongation of fastening bolt, stablize mould dimension, avoid casting flaw to produce, improve the mechanical performance of foundry goods.
The technical scheme that its purpose that realizes the utility model adopts is: a kind of bracing means of square casting mold, comprise two block pressur plates and two arm-ties, two block pressur plates lay respectively at the last plane and the bottom surface of the casting mold of reinforcing, the two sides of the casting mold of reinforcing are stretched out at the pressing plate two ends, the pressing plate two ends are provided with long through-hole, long through-hole two sides correspondence is provided with connecting hole, arm-tie is provided with adjustment hole, arm-tie runs through two block pressur plates by the long through-hole of pressing plate, and pass the connecting hole of pressing plate long through-hole two sides and the adjustment hole on the arm-tie by pin, pressing plate is fixedlyed connected with arm-tie.
Handling is for convenience installed, and described arm-tie one end is provided with hoisting ring, and is better for guaranteeing consolidation effect, with pressing plate with after arm-tie is connected, again at the oblique part of filling in of embedding between the plane on pressing plate and the casting mold of reinforcing.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, can prevent effectively that ductile cast iron casting is after cast, because arch upward in the top of the sandbox that the internal stress effect that graphite expansion produces during molten steel solidification causes and the elongation of fastening bolt, thereby stablize mould dimension, reduce casting flaw, improve the mechanical performance of foundry goods.
