Description
Technical Field
[0001] The utility model relates to the technical field of die casting, in particular to a die casting soup ladle. Background Art
[0002] The main processes for aluminum alloy forming include gravity casting, low-pressure casting, squeeze casting, liquid forging and high-pressure die casting. For the aluminum alloy high-pressure die casting process, there are two ways to add aluminum liquid: one is the traditional soup taking machine, which controls the position of the soup taking spoon to take aluminum liquid and pour it into the pressure chamber. The other is a quantitative furnace, which adjusts the pressure in the furnace to press the aluminum liquid out of the furnace and enter the pressure chamber through the guide groove.
[0003] Traditional soup taking machines and soup taking spoons have the advantages of simple structure, easy troubleshooting, and relatively low cost. However, there are also some disadvantages in the application process: it is easy to scoop the aluminum liquid oxides and slag in the furnace into the soup spoon, pour them into the pressing chamber, and press them into the product, resulting in defects in the product. The advantages of the traditional quantitative furnace are: during the application process, the aluminum liquid has been in a closed environment, without contact with the outside air, almost no oxides are produced, the inlet of the pressed aluminum liquid is also below the aluminum liquid level in the furnace, and the slag cannot be brought into the aluminum liquid. The disadvantages are complex structure, difficult troubleshooting, relatively high cost, and inconvenient maintenance. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a die-casting soup ladle, the purpose of which is to isolate oxides and slag on the surface of molten aluminum in a furnace during the soup taking process, thereby improving the purity of the taken molten aluminum and thus improving the quality of die-castings.
[0005] The technical solution adopted by the utility model is as follows:
[0006] A die-cast soup spoon, comprising a soup spoon body, a soup taking opening is arranged on the upper edge of the front end of the soup spoon body, a soup pouring opening is arranged on the rear end of the soup spoon body, a baffle plate 1 is arranged outside the front end of the soup spoon body, and a baffle plate 2 is arranged on the upper part of the baffle plate 1;
[0007] A gap is formed between the inner wall of the baffle plate 1 and the outer wall of the front end of the soup ladle body, which is used to form a channel for the aluminum liquid to flow in. The entrance of the channel is flush with the lower end surface of the baffle plate 1, and the lower end surface of the baffle plate 1 is lower than the bottom surface of the soup outlet, so that the aluminum liquid flows into the channel and then flows upward and finally flows into the soup ladle body from the soup outlet;
[0008] The lower end of the baffle plate 2 is butted against the upper end surface of the baffle plate 1 to form a cover-shaped structure with a convex arc surface located at the upper front end of the soup spoon body. The cover-shaped structure is open at one end, and an inclined surface is formed at the open end. The lowest point of the inclined surface is located on the upper end surface, and the lowest point of the inclined surface is lower than the intersection point of the inclined surface and the soup spoon body. The upper end surface is a plane, and the angle between it and the inclined surface is greater than 45°.
[0009] Further technical solutions are:
[0010] The two side walls of the soup spoon body on both sides of the baffle plate 1 are correspondingly connected.
[0011] The upper edge of the front end of the soup spoon body is flush with the upper end surface of the baffle plate 1.
[0012] The soup spoon body is made of cast iron or cast steel, and the baffle plate 1 and baffle plate 2 are both made of steel.
[0013] The soup spoon body, baffle plate 1 and baffle plate 2 are formed separately and then connected in sequence;
[0014] Alternatively, the soup spoon body is integrally formed with the baffle plate 1 and then connected with the baffle plate 2;
[0015] Alternatively, the baffle plate 1 and the baffle plate 2 are integrally formed and then connected to the soup spoon body.
[0016] The inner and outer surfaces of the soup spoon body, baffle plate 1 and baffle plate 2 are all provided with protective coatings.
[0017] A connecting arm is provided on the soup spoon body.
[0018] The beneficial effects of the utility model are as follows:
[0019] (1) By combining the amount of soup required each time, the angle of the soup spoon deviating from the Z axis, the size of the gap, and the height of the lower end surface of the baffle plate in the first step are reasonably set, and the utility model can basically completely isolate the oxides and scum on the surface of the aluminum liquid in the furnace, greatly improving the purity of the aluminum liquid and effectively improving the quality of the die castings. The scrap rate of the die castings cast by ordinary soup spoons due to oxides and scum was originally 5%, and the scrap rate was reduced to 1%.
[0020] The specific advantages include: first, the baffle plate 1 and the soup outlet are designed to be staggered. When working, the baffle plate 1 first contacts the surface of the aluminum liquid in the furnace, which effectively isolates and blocks the oxides and scum outside the baffle plate 1 at the first time, and does not contact the soup outlet at all; second, the soup spoon must sink into the furnace at a certain angle to get the aluminum liquid, which will cause the upper end face of the soup spoon body to be immersed in the aluminum liquid, and also submerge the baffle plate 1. The utility model is provided with a baffle plate 2, which can continue to play the role of the baffle plate 1, while preventing the upper end face of the soup spoon body from being immersed in the aluminum liquid. The aluminum liquid is directly poured in from the soup outlet, preventing the oxides and scum from entering the inside of the soup spoon body.
[0021] (2) By using the die-cast soup ladle of the utility model, the problem of operational safety protection is solved and the workload of employees is reduced. In normal production, employees need to remove oxides and slag from the surface of the aluminum liquid in the furnace for 2 hours. During this process, the reciprocating motion of the soup ladle machine may collide with the employees and cause injuries. At present, employees only need 4 hours or even longer to remove oxides and slag from the surface of the aluminum liquid in the furnace, which greatly reduces the chance of contact between employees and the soup ladle machine.
[0022] Other features and advantages of the present invention will be described in the following description or will be understood by implementing the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] The specific implementation of the present utility model is described below with reference to the accompanying drawings.
[0030] See also Figures 1 to 4 The die-cast soup spoon of this embodiment comprises a soup spoon body 1, a soup taking opening 4 is provided at the upper edge 101 of the front end of the soup spoon body 1, a soup pouring opening 6 is provided at the rear end of the soup spoon body 1, a baffle 1 2 is provided outside the front end of the soup spoon body 1, and a baffle 2 3 is provided on the upper part of the baffle 1 2;
[0031] A gap is formed between the inner wall of the baffle 1 2 and the outer wall of the front end of the soup spoon body 1. Figure 3The gap 9 shown is used to form a channel for the aluminum liquid to flow in. The entrance of the channel is flush with the lower end surface 201 of the baffle 1 2. The lower end surface 201 of the baffle 1 2 is lower than the bottom surface 401 of the soup outlet 4, so that the aluminum liquid flows into the channel and then flows upward and finally flows into the soup spoon body 1 from the soup outlet 4.
[0032] The lower end of the baffle plate 2 3 is butted against the upper end surface 202 of the baffle plate 1 2 to form a hood-shaped structure with an outwardly convex arc surface located at the upper front end of the soup spoon body 1. The hood-shaped structure is open at one end, and an inclined surface 301 is formed at the open end. The lowest point of the inclined surface 301 is located on the upper end surface 202, and the lowest point of the inclined surface 301 is lower than the intersection point 7 of the inclined surface 301 and the soup spoon body 1. The upper end surface 202 is a plane, and the angle a between it and the inclined surface 301 is greater than 45°. Figure 4 shown.
[0033] As a specific implementation, the soup ladle body 1 is provided with a connecting arm 5 for connecting to a soup dispenser.
[0034] As a specific implementation, the upper edge of the front end of the soup spoon body 1 is flush with the upper end surface of the baffle 1 2 .
[0035] The die-casting soup ladle of this embodiment can be installed on the soup ladle machine and can be used normally. In the process of taking aluminum liquid, while ensuring that the set soup amount is taken, the oxides and scum on the surface of the aluminum liquid in the furnace are blocked outside the baffle plate to prevent them from entering the soup ladle, so that the purity of the aluminum liquid is guaranteed, the defects of the product are solved, and the product quality is improved.
[0036] The die-cast soup ladle of this embodiment includes several steps in operation. Figure 5 The four states from left to right correspond to the four steps of the die-cast soup spoon of this embodiment when taking liquid during the downward movement. The working steps of the soup spoon include the following:
[0037] 1. The first step: install the soup spoon on the soup machine through the connecting arm 5. The soup machine drives the soup spoon to rotate a certain angle through the connecting arm 5, keeps the soup spoon deviated from the Z axis at a certain angle, and ensures that the soup outlet 4 is lower than the pouring outlet 6. Then the soup machine drives the soup spoon to move to the surface of the aluminum liquid in the furnace 8. Figure 5 As shown in state 1, the outer wall of the bottom of the spoon body 1 of the spoon begins to contact the aluminum liquid, and as it slowly moves downward, the oxides and scum on the surface of the aluminum liquid can be pushed away.
[0038] 2. Step 2: Take the spoon and continue to move it downward until the outer wall of baffle 2 contacts the surface of aluminum liquid in the furnace 8. Figure 5 As shown in state 2. At this time, the outer wall of baffle 1 2 starts to work, pushing the oxides and slag on the surface of the aluminum liquid in the furnace outward.
[0039] 3. Step 3: When the gap 9 formed by the outer wall of the spoon body 1 and the inner wall of the baffle 2 is immersed in the aluminum liquid, Figure 5 The gap 9 forms a liquid inlet channel, at which time the oxides and slag on the surface of the aluminum liquid in the furnace are completely isolated and blocked outside the baffle 2, and the aluminum liquid below the aluminum liquid surface 8 in the furnace without oxide and slag contamination enters from the bottom entrance of the liquid inlet channel.
[0040] 4. Step 4: The spoon continues to move downward, the aluminum liquid reaches the soup taking port 4 through the liquid inlet channel, and then slowly enters the inside of the spoon body 1. When the aluminum liquid enters the inside of the spoon body 1, the outer wall of the baffle 2 3 begins to isolate and block the oxides and scum on the surface 8 of the aluminum liquid from outside, and prevents them from entering the inside of the spoon body 1 from above. Figure 5 As shown in state 4.
[0041] 6. Step 5: After the soup taking machine takes the set value of aluminum liquid, it starts to raise the soup spoon from the furnace to above the aluminum liquid surface 8 for measurement. If too much is taken, the soup spoon is rotated again to pour the excess aluminum liquid back into the furnace from the soup taking port 4. During the pouring process, the poured aluminum liquid is oxidized and floats on the aluminum liquid surface 8 in the furnace.
[0042] 7. Step 6: When the metering is completed, the soup taking machine starts to move the soup spoon to the feeding port of the injection chamber, and pours the aluminum liquid into the feeding port of the injection chamber through the soup pouring port 6 of the soup spoon. After pouring, the first step is started again, and the reciprocating action is repeated.
[0043] In this embodiment, the outer wall of the soup spoon is first used to "break the ice" during the descent process to push away the floating scum, and then the baffle 2 is used to "break the ice" during the descent process of the soup spoon to continue to push away the floating scum, and the gap 9 is used to introduce the aluminum liquid below the surface of the aluminum liquid in the furnace without oxide and scum contamination into the soup outlet 4 and into the soup spoon. Then the soup spoon needs to continue to move downward to get the required amount of soup. In the process of continuing to move downward, the baffle plate 2 3 begins to play a role, and uses its convex arc surface to further push away the scum on the surface of the aluminum liquid near the soup spoon during the descent process. In addition, because "the lowest point of the inclined surface 301 is located on the upper end surface 202, and the lowest point of the inclined surface 301 is lower than the intersection point 7 of the inclined surface 301 and the soup spoon body 1, the upper end surface 202 is a plane, and the angle a between it and the inclined surface 301 is greater than 45°", while ensuring the amount of soup taken, when the soup spoon reaches the lowest position, the inclined surface 301 is higher than the aluminum liquid surface 8, preventing the aluminum liquid from pouring into the soup spoon from the open end of the baffle plate 2 3.
[0044] In combination with the amount of soup required each time, the angle of the soup spoon deviating from the Z axis, the size of the gap 9, and the height of the lower end surface 201 of the baffle 2 in the first step are reasonably set. The utility model can basically achieve complete isolation of scum oxides and the like during the liquid taking process.
[0045] As a specific implementation, the two side walls of the soup spoon body 1 on both sides of the baffle 2 are correspondingly connected.
[0046] As a specific implementation, the soup spoon body 1 is made of cast iron or cast steel, and the baffle 1 2 and the baffle 2 3 are both made of steel.
[0047] As a specific implementation, the soup spoon body 1, baffle one 2, and baffle two 3 are formed separately and then connected in sequence, wherein the soup spoon body 1 can be formed by casting, and baffle one 2 and baffle two 3 can be formed by stamping; or, the soup spoon body 1 and baffle one 2 are formed as one piece and then connected to baffle two 3; or, baffle one 2 and baffle two 3 are formed as one piece and then connected to the soup spoon body 1.
[0048] All of the above connection methods can be welded.
[0049] As a specific implementation, the inner and outer surfaces of the soup spoon body 1, baffle 1 2, and baffle 2 3 are all provided with a protective coating.
[0050] The gap 9 between the baffle 1 2 and the soup spoon body 1, and the opening with the inclined surface 301 set on the baffle 2 3, also make it convenient to insert tools. The baffle 1 2, the baffle 2 3 and the soup spoon body 1 are coated with a protective coating, which is used for heat insulation to prevent melting due to long-term use, and is also used to prevent aluminum liquid from adhering to the outer wall to avoid aggravating aluminum liquid oxidation.
[0051] The soup spoon of this embodiment has a simple structure and can be modified on the existing commonly used soup spoon by casting. The production cost is low. It can be assembled by modifying the original commonly used soup spoon with only a few pieces of waste steel plates. If it is cast in one piece, only a little more material is needed.
[0052] Compared with the conventional ceramic soup spoon, the soup spoon of the present embodiment is much more convenient to use and maintain. It is not necessary to bake the soup spoon before use, and then tighten the screws of the mounting arm of the soup spoon to prevent the ceramic soup spoon from being damaged. At the same time, it should not be bumped during use, which will also cause damage to the ceramic soup spoon.
[0053] Those skilled in the art can understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
