Abstract
A simple and easy sand box for a lost foam steel tube belongs to the field of casing tools, comprises a sand box body (1) and a vacuum negative pressure system (2) and is characterized in that the vacuum negative pressure system (2) is a closed pipeline formed by vertically welding a plurality of steel tubes in cross mode, the closed pipeline is horizontally fixed at the bottom of the sand box body (1) through a plurality of fixing devices, an upper plane of the closed pipeline are evenly provided with regular holes, a screen (3) is covered at the upper portion of the closed pipeline, and one side of the closed pipeline is provided with a tube opening extending out of the sand box body (1) to be connected with a short tube. The simple and easy sand box for the lost foam steel tube is suitable for casts with simple shape structures and low requirement for negative pressure fields, simple in structure, capable of reducing casting cost, convenient to maintain and strong in applicability.
Description
Technical field
The simple and easy sandbox of disappearance mould steel pipe belongs to casting frock field, is specifically related to a kind of simple and easy sandbox of the fairly simple steel pipe of casting structure that is applicable to.
Background technology
In the lost foam casting industry of China, sandbox is the key equipment during lost foam casting is produced at present, and complicated sandbox is the sandbox that generally uses in the casting; When making foundry goods in sandbox, vacuumize, reaches by this sandbox the most reasonably negative pressure field; Advantage is that the trunkful foundry goods moulding of cast is good, does not have defective, and is sturdy and durable; Be applicable to the combination of complex structure or multi-model, and the casting frock of having relatively high expectations for casting quality.
The complicated sandbox body that generally uses now adopts steel plate, channel-section steel, stainless (steel) wire and grizzly bar etc. to make shaping; Nexine requires good permeability; Outer requirement sealing will be got well, and is suitable for the various trades mark, various materials such as steel, iron, aluminium, the large, medium and small all kinds of foundry goods of different structure.Casting dimension precision is high, uniformity, and the smooth surface precision is near hot investment casting, and internal structure is stable, has got rid of defectives such as sand holes, pore.This special requirement makes that its structure is very complicated, makes trouble, if deal with improperly, after the sandbox of production put into production, the foundry goods of producing can produce various problems, such as crush, and pore, shrinkage porosite or the like.
Because the complex structure of complicated sandbox, manufacturing conditions is harsh, and the sandbox investment is big, and the casting cost is high.So it is simple for some shape and structures; The less demanding foundry goods of negative pressure field during cast; Use so complicated sandbox just to increase manufacturing cost, and be not complementary, so need adopt simple and easy sandbox according to practical condition with actual demand; To improve casting yield, reduce the foundry goods manufacturing cost.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of prior art, provide a kind of shape and structure that is applicable to simple and to the simple and easy sandbox of disappearance mould of the less demanding foundry goods in negative pressure field.
The utility model solves the technical scheme that its technical problem adopted: the simple and easy sandbox of this disappearance mould steel pipe; Comprise sandbox body and negative pressure of vacuum system; It is characterized in that: negative pressure of vacuum system many closing pipe lines that the steel pipe square crossing welds together of serving as reasons, closing pipe line is horizontally fixed on sandbox body bottom through a plurality of fixtures, evenly has regular aperture on the last plane of closing pipe line; Communicate with sandbox body inner air; Closing pipe line top covers screen cloth, and a side of closing pipe line is provided with the mouth of pipe short tube external with stretching out sandbox and is connected, and short tube links to each other with the external vacuum pump system of sandbox.
The steel pipe of described composition closing pipe line comprises first steel pipe of many diameter 57mm and second steel pipe of two diameter 108mm, and two second steel pipes are located at the left and right sides of closing pipe line.
Described fixture comprises fixed head and fastening bolt, and fixed head is a square plate, and Si Jiaochu has bolt hole, and fastening bolt passes bolt hole fixed head and negative pressure of vacuum system are fixed on the sandbox body base plate.During cleaning sandbox body, can dismantle fixed head 6 and fastening bolt 7.
Described sieve number is 100 orders, can prevent that particulate material from sucking the negative pressure of vacuum system.
Compared with prior art, the beneficial effect that had of the simple and easy sandbox of disappearance mould steel pipe of the utility model is:
1, simple in structure, reduction casting cost: the negative pressure of vacuum system in the sandbox body is welded by the steel pipe intersection; Be drilled with the aperture that is uniformly distributed with on the steel pipe, the formation air chamber that communicates with sandbox body inside is compared with the making of existing sandbox body bottom, the large-area steel plate boring of case sidewall, welding, complicated air chamber; Consumptive material is few; Time saving and energy saving, simple in structure, reduce the casting cost;
2, dismounting is simple, easy to maintenance: the negative pressure of vacuum system is fixed in the sandbox body through fastening bolt and fixed head, during cleaning sandbox bottom, can dismantle fixed head and fastening bolt, and vacuum system is not had any influence, greatly reduces the difficulty of maintenance;
3, applicability strong, improve the quality of products: this sandbox goes for the various trades mark, various material, all kinds of simple foundry goods of different structure, casting dimension precision is high, non-trimming and burr have alleviated labour intensity, have improved casting quality.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the cutaway view of the utility model.
Wherein: 1, sandbox body 2, negative pressure of vacuum system 3, screen cloth 4, first steel pipe 5, second steel pipe 6, fixed head 7, fastening bolt 8, short tube.
Fig. 1～2nd, the most preferred embodiment of the simple and easy sandbox of the utility model disappearance mould steel pipe further specifies below in conjunction with 1～2 pair of the utility model of accompanying drawing:
The specific embodiment
With reference to accompanying drawing 1～2:
The simple and easy sandbox of this disappearance mould steel pipe; Comprise sandbox body 1 and negative pressure of vacuum system 2, negative pressure of vacuum system 2 many closing pipe lines that the steel pipe square crossing welds together of serving as reasons, closing pipe line is horizontally fixed on sandbox body 1 bottom through a plurality of fixtures; Evenly have the aperture of rule on the last plane of closing pipe line; Communicate with sandbox body inner air, it is 100 purpose screen clothes 3 that closing pipe line top covers the order number, can prevent that particulate material from sucking negative pressure of vacuum system 2.Short tube 8 outside one side of closing pipe line is provided with the mouth of pipe and stretches out sandbox body 1 is connected, and short tube 8 links to each other with sandbox body 1 outer vacuum pump system.
The steel pipe of forming closing pipe line comprises that 5, two second steel pipes 5 of second steel pipe of first steel pipe 4 and two the diameter 108mm of many diameter 57mm are located at the left and right sides of closing pipe line.
