Abstract
The utility model discloses a filling device for a large casting resin sand box or a pit, in particular to a filling device used for a resin sand box of a large special-shaped casting. A box body of the filling device is a hollow rectangle, and the hollow internal part is internally and symmetrically provided with lifting lugs. According to the size of the needed use space, the filling devices can be used independently and also can be used in a combined manner. As the box body with the same standard is selected, the use is more flexible, and the filling devices can be used independently and also can be used in a combined manner. As the built-in lifting lugs are adopted, the forming is more convenient, and the use amount of the resin sand can be reduced obviously, therefore, the use amount of resin and curing agent is reduced, and simultaneously, the work load for regeneration of the sand is reduced. The formed sand type reduces the thickness of the casting sand, the radiating speed is promoted after casting and setting, the temperature holding time is shortened, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of heavy castings resin sandbox or melt pit filling device, and a kind of specifically large scale special-shaped foundry goods is in the resin sandbox or the filling device that uses of melt pit.
Background technology
Heavy castings tradition uses clay-bonded sand to produce foundry goods because its production cost is low, so consider to reduce cost less.Now selected resin sand is owing to it has any surface finish, corner angle are clear, dimensional accuracy is high, casting quality is good, are specially adapted to large scale special-shaped foundry goods.Can raise labour efficiency simultaneously alleviates working strength of workers, and its utilization rate improves gradually.Because the cost of resin sand is higher; so how people have thought a lot of methods on satisfying the use amount that reduces resin sand when using; for example: select for use the ingot mould scrapped or other discards as filler; can reduce the use amount of resin sand; but be difficult for hanging out when playing type, and this type of filler out-of-shape, outer profile size do not wait and use its inconvenience.
Summary of the invention
In order to overcome above-mentioned technical deficiency, the utility model provides a kind of heavy castings resin sandbox or melt pit filling device, and this device has effectively reduced the use of resin sand, has alleviated working strength of workers.
The technical scheme that its technical problem that solves the utility model adopts is: casing is the hollow, rectangular body, and its hollow inside is arranged with hanger.
According to the size of required usage space, filling device can use separately, also can several be used in combination.
The beneficial effects of the utility model are: owing to selected uniform box-type filling device for use, use more flexibly, both may be used alone, can also be used in combination.Since more convenient when having adopted built-in hanger to play type, can reduce the use amount of resin sand significantly, thereby reduce the use amount of resin and curing agent, reduced the workload of sand reclamation simultaneously.The sand mold of moulding has reduced molding sand thickness, and cast typing back increases radiating rate, shortens temperature retention time, has reduced production cost.
Description of drawings
Fig. 1 is the utility model heavy castings resin sandbox or melt pit filling device structural representation.
Among the figure 1, casing, 2, hanger.
The specific embodiment
As shown in Figure 1, casing 1 is the hollow, rectangular body, and its hollow inside is arranged with hanger 2.
In resin sandbox or melt pit,, respectively one of filling device or several are arranged use, reduce the thickness of molding sand according to shape, length, the diameter of large scale special-shaped foundry goods, cast typing back increases radiating rate, shorten temperature retention time, filling device is hung out, can accelerate cooling velocity of casting.
Claims (1)
1. heavy castings resin sandbox or melt pit filling device, it is characterized in that: casing (1) is the hollow, rectangular body, and its hollow inside is arranged with hanger (2).
