Abstract

The utility model discloses a fastening device for casting molds, which is applied to fasten round and polygonal casting molds made by box molding during the casting process of nodular cast iron. The fastening device comprises two Y-shaped press plates and three pulling plates. The two press plates are arranged on the top flat surface and the bottom surface of a casting mold to be fastened respectively; and the three end parts of each Y-shaped press plate are exposed outside the peripheral side surfaces of the casting mold to be fastened. Elongated slot holes are formed at the three end parts of each Y-shaped press plate, and connecting holes are formed on the two side surfaces of each elongated slot hole correspondingly. Adjusting holes are formed at the two ends of each pulling plate. The pulling plates pass through the two press plates via the elongated slot 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 slot hole of the press plates and the adjusting holes on the pulling plates. 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

The fastener of casting casting mold

Technical field

The utility model relates to the Foundry Production technical field, and especially a kind of being applicable to when casting ductile cast iron casting cast the fastener that casting mold is reinforced to the circle and the polygon that adopt the box moulding gained.

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 fastener of casting casting mold is provided, it can prevent effectively that ductile cast iron casting is after cast, because arching upward and the elongation of fastening bolt of the sandbox top that the internal stress effect that graphite expansion produces when solidifying causes, stablize mould dimension, avoid casting flaw to produce, improve the mechanical performance of foundry goods.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of fastener of casting casting mold, comprise two Y shape pressing plates and three arm-ties, two block pressur plates are arranged at the last plane and the bottom surface of the casting mold of reinforcing respectively, three ends of Y shape pressing plate stretch out the peripheral side of fastening casting mold, three ends of Y shape pressing plate are provided with long slot bore, correspondence is provided with connecting hole in the long slot bore two sides, three arm-tie two ends are provided with adjustment hole, arm-tie runs through two block pressur plates by the long slot bore of pressing plate, and pass the connecting hole of pressing plate long slot bore 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, the oblique part of filling in of embedding between the plane on pressing plate and institute fastening casting mold again.

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.

The specific embodiment.

In conjunction with the accompanying drawings and embodiments the utility model is further described now.These accompanying drawings only illustrate basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.

As Fig. 1 Fig. 2 and a kind of fastener of casting casting mold shown in Figure 3, when being applicable to the casting ductile cast iron casting, the circle and the polygon casting casting mold 1 that adopt the box moulding gained are reinforced, comprise two Y shape pressing plates 2 and three arm-ties 3, Y shape pressing plate 2 and arm-tie 3 materials are casting pig not yielding and that intensity is good, two Y shape pressing plates 2 are arranged at the last plane and the bottom surface of the casting mold of reinforcing 1 respectively, three ends of Y shape pressing plate 2 stretch out the peripheral side of fastening casting mold 1, three ends of Y shape pressing plate 2 are provided with long slot bore 2-1, the two sides correspondence of long slot bore 2-1 is provided with a plurality of connecting hole 2-2, with casting mold 1 requirement of satisfying different radial dimensions, arm-tie 3 is provided with a plurality of adjustment hole 3-1, can adapt to casting mold 1 requirement of differing heights, the long slot bore 2-1 of 2 three ends of Y shape pressing plate can import and position-limiting action 3 of arm-ties, arm-tie 3 runs through two Y shape pressing plates 2 by the long slot bore 2-1 of Y shape pressing plate 2, and pass the connecting hole 2-2 of Y shape pressing plate 2 long slot bore 2-1 two sides and the adjustment hole 3-1 on the arm-tie 3 by pin 4, both fixedly connected with Y shape pressing plate 2 and arm-tie 3, form inelastic clamping frames, simultaneously at Y shape pressing plate 2 with after arm-tie 3 is connected, embedding tiltedly plug part 5 on Y shape pressing plate 2 and the casting mold of reinforcing 1 between the plane again, desirable more to guarantee consolidation effect, in addition, install for the ease of handling, be provided with hoisting ring 6 in the arm-tie upper end, install to make things convenient for handling.

When the utility model uses, earlier a Y shape pressing plate 2 is preset in the placing sand layer 7, wipe placing sand off and make that the plane is consistent on itself and the Y shape pressing plate 2, on plane on the Y shape pressing plate 2, place casting mold 1 then, after treating that casting mold 1 mould assembling end finishes with bolted, utilize the hoisting ring 6 on the arm-tie 3 that three arm-ties 3 are sling, put into the long slot bore 2-1 of 2 three ends of Y shape pressing plate respectively, by the connecting hole 2-2 of Y shape pressing plate 2 long slot bore 2-1 both sides and the adjustment hole 3-1 on the arm-tie 3, with pin 4 Y shape pressing plate 2 is fixedlyed connected with three arm-tie 3 lower ends, again another Y shape pressing plate 2 is placed the last plane of casting mold 1, and the long slot bore 2-1 by 2 three ends of Y shape pressing plate, the upper end that Y shape pressing plate 2 is inserted in already installed three arm-ties 3 respectively, same by the connecting hole 2-2 of Y shape pressing plate 2 long slot bore 2-1 two sides and the adjustment hole 3-1 on the arm-tie 3, with pin 4 Y shape pressing plate 2 is fixedlyed connected with three arm-tie 3 upper ends, embedding oblique plug part 5 on Y shape pressing plate 2 and the casting mold of reinforcing 1 between the plane and striking tightly, so just casting mold 1 can be firmly fastened in bracing means described in the utility model at last
