Abstract
The utility model discloses a narrow diameter cast iron profile shaping apparatus. The utility model comprises a pouring basin and a straight pouring channel which is communicated with the pouring basin. The straight pouring channel is communicated with a thin and long mold cavity. The straight pouring channel and the mold cavity are arranged in a sealed vacuum box. The apparatus of the utility model adopts the suction cast under the condition of vacuum, the mold-filling capacity of iron liquids is evidently enhanced, the cast iron profile of phi three millimeters to phi ten millimeters is available and the length of the profile can reach over one meter. The technology product rate of the cast iron profile is high, the cost is lower, and the surface quality, the linearity and the dimensional precision are high. The defects of air holes, insufficiently pouring, slag inclusion, etc. can not almost generate.
Description
Technical field
The utility model belongs to casting technology field, relates to a kind of building mortion of cast iron profile material, particularly a kind of cast iron profile material building mortion of thin diameter.
Background technology
As extraordinary welding material, electrode for cast iron, welding wire are indispensable in engineering fields such as cast iron materials welding and ironcasting defect repair.Because cast iron is fragile material, core wire (silk) can't resemble steel and the non-ferrous metal by methods such as drawing, rolling or extruding and produce, and can only adopt the method for liquid shaping, and promptly casting method obtains.In the prior art, the method that is used for cast iron core wire (silk) casting has hot investment casting, ordinary sand casting and permanent mold casting.Hot investment casting is easy to guarantee the forming quality of core wire (silk), but its cost is too high, seldom selects for use as core wire (silk) manufacturing process; Although sand casting casting cost is low, product yield is low, only 20～40%, and also the dimensional accuracy of welding wire and linearity are difficult to guarantee; Permanent mold casting is better than sand casting slightly at aspects such as core wire (silk) quality, production efficiencys, but the casting mold cooldown rate is big, and iron liquid is mobile poor, and the core wire that is obtained (silk) length is very limited.Because fine diameter cast iron alloy existing particular difficulty on forming technique, the diameter of the cast iron core wire (silk) that the routine casting method is obtained is usually in Φ 8mm～Φ 10mm scope.
In addition, the minimum diameter that continuous casting technology can the steady production cast iron profile material is Φ 18mm in Japan, is Φ 20mm in China, is far longer than the dimensions of core wire (silk), can't satisfy the production needs of cast iron core wire (silk).
In recent years, development and application along with low chilling tendency, the cast iron homogeneous welding rod of high cracking resistance (silk), greatly reduce the welding temperature of ironcasting, make the preheat temperature of weldment be reduced to about 150 ℃～200 ℃ from 650 ℃ of hot weldering, thus the arc cold-welding welding that has realized the ironcasting homogeneous electrode with repair.Used electrode size has also obtained reducing effectively, is reduced to Φ 3mm～Φ 5mm from Φ 8mm～Φ 10mm.Traditional forming technique has been difficult to satisfy the production needs of new type cast iron welding rod.
Summary of the invention
Have the requirement that foundry engieering can not satisfy cast iron core wire (silk) diameter now in order to solve, the purpose of this utility model is to provide a kind of building mortion of fine diameter cast iron profile material, utilizes this device can obtain the cast iron profile material of Φ 3mm～Φ 10mm.
The technical scheme that the utility model adopted is, the fine diameter cast iron profile material building mortion comprises a pouring basin and the sprue that communicates with it, and sprue also is communicated with die cavity, and sprue and die cavity are positioned in the vacuum tank of a sealing.
The diameter of die cavity is Φ 3mm～Φ 10mm.
The beneficial effects of the utility model are:
(1) inhale casting because device of the present utility model adopts under vacuum condition, the mold-filling capacity of iron liquid is strengthened, can obtain the cast iron profile material of Φ 3mm～Φ 10mm, profile length reaches more than the 1m, and adjustable length.
(2) utilize cast iron profile material product yield that the utility model device obtains up to 80%～90%, surface quality, linearity and dimensional accuracy be easy to guarantee that production cost is low, and eliminated pore to greatest extent, defectives such as misrun, slag inclusion.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Accompanying drawing is the structural representation of the utility model building mortion.
Among the figure, 1. vacuum tank, 2. sprue, 3. sealing ring, 4. fastening bolt, 5. pouring basin, 6. iron liquid, 7. sealing patch, 8. lute bar, 9. aspirating hole, 10. die cavity, 11. locating pieces.
The specific embodiment
Referring to accompanying drawing, the utility model fine diameter cast iron profile material building mortion comprises a pouring basin 5 and the sprue 2 that communicates with it, the diameter of pouring basin 5 is greater than the diameter of sprue 2, and sprue 2 also is communicated with the die cavity 10 that diameter is Φ 3mm～Φ 10mm, forms the staged cast.Sprue 2 and die cavity 10 are positioned in the vacuum tank 1 of a sealing, and pouring basin 5 is fixed together by fastening bolt 4 loam cake with vacuum tank 1, between the loam cake of pouring basin 5 and vacuum tank 1, between vacuum tank 1 and the loam cake sealing ring 3 is installed all.
According to the diameter of the required cast iron profile material that obtains, adopt self-hardening sand or oil-sand moulding, produce the casting mold and sclerosis that includes sprue 2 and die cavity 10 after, casting mold is placed vacuum tank 1, fix the position of casting mold with locating piece 11.Before the cast iron liquid 6, sprue 2 and pouring basin 5 block by sealing patch 7 and lute bar 8, vacuumize by aspirating hole 9, when the vacuum in the vacuum tank 1 reaches 30kPa～60kPa, iron liquid 6 is poured in the pouring basin 5, make it be in full state, seal patch 7 and melted voluntarily by the effect of high temperature iron liquid 6 this moment, iron liquid 6 enters die cavity 10 by sprue 2 under gravity and suction function, because the bigger pressure differential of die cavity 10 inside and outside existence, the mold-filling capacity of iron liquid 6 significantly strengthens, and under the effect of negative pressure, finishes and fills type, cooling and process of setting and form fine diameter cast iron profile material.
Utilize device of the present utility model can obtain the cast iron profile material of Φ 3mm～Φ 10mm, profile length reaches more than the 1m, and can reach the purpose of regulating profile length by regulating die cavity 10 inside and outside pressure differentials as required.
Claims (2)
1. fine diameter cast iron profile material building mortion, the sprue (2) that comprises a pouring basin (5) and communicate with it, it is characterized in that described sprue (2) also is communicated with die cavity (10), sprue (2) and die cavity (10) are positioned in the vacuum tank (1) of a sealing.
