Description

Technical Field

[0001] The utility model relates to the technical field of semi-solid processing injection, in particular to an injection structure of a semi-solid slurry. Background Art

[0002] Semi-solid forming is a special metal forming process that involves stirring the liquid metal as it solidifies, and then obtaining a slurry with a solid phase component of about 50% or even higher at a certain cooling rate. This slurry is then formed by die casting or other forming methods.

[0003] Semi-solid injection molding is a new type of metal forming technology, also known as semi-solid injection molding technology or semi-solid die casting technology. Its principle is to heat the metal material to a semi-solid state, that is, a state between liquid and solid, and then transfer it from the slurry pool to the mold for die casting.

[0004] There are two main molding processes for semi-solid die-casting technology: rheocasting and thixocasting. Rheocasting first heats the raw ingot of the alloy to the state of liquid metal, then stirs the metal using stirring technology to obtain a semi-solid slurry, and finally performs die casting. However, after obtaining the semi-solid slurry, thixocasting does not perform die casting of the product, but uses quenching to obtain an ingot, and after the ingot cools, the ingot is cut into billets, and then the billets are reheated to a semi-solid state, and then the semi-solid billets are die-casted by a die-casting machine.

[0005] Therefore, in the technical field of semi-solid injection, there is a patent with publication number CN209614180U that discloses a semi-solid slurry injection structure. The patent discloses a semi-solid slurry injection structure by "disclosing a semi-solid slurry injection structure, which includes a shot tube, a shot mechanism and a pouring chute. The first end of the shot tube passes through the fixed mold plate of the die-casting mold and is connected to the inlet of the fixed mold plate. The hammer head of the shot mechanism is movably arranged at the second end of the shot tube. The portion of the shot tube located at the fixed mold plate is provided with a feed port, and the first end of the pouring chute is connected to the feed port. The pouring chute The technical solution of "it is inclined, the inner wall of the pouring chute is wavy, and the outer wall is provided with a heating kit" realizes the technical effect of "the utility model shortens the injection tube and arranges a pouring chute for producing semi-solid slurry on the side of the die-casting mold, so that the formed semi-solid slurry directly enters the pressure chamber of the injection tube and is collected, thereby improving the filling degree of the liquid; and the formed semi-solid slurry has high viscosity, stable filling, not easy to entrain air, and can well fill the interior of the cavity, thereby effectively solving the defects of die-casting products such as cracks, looseness, and pores".

[0006] However, in the process of transferring the slurry from the slurry pool to the mold cavity by the semi-solid injection structure of this patent, due to the different sizes of molds, the transfer process cannot perfectly adapt to the sizes of various types of molds and correctly transfer the slurry to the cavity, which is prone to transfer leakage problems. There is room for improvement. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0026] In an embodiment of the utility model, a semi-solid slurry injection structure includes an injector 1, a flow controller 2 is provided on one side of the injector 1, and an interferometer 4 is provided on the other side of the injector 1. A flow control ball head 22 is provided in the flow controller 2, and the flow control ball head 22 controls the slurry injection speed of the injector 1 by its activity in the injector 1. A flow control plate 43 is provided in the interferometer 4, and the flow control plate 43 controls the injection flow rate of the injector 1 by its activity in the injector 1. The interferometer 4 includes a mounting seat 41, a rotating rod 42 and a flow control plate 43. The mounting seat 41 is fixedly connected to the injector 1, and the rotating rod 42 is provided with two groups and both are screwed to the mounting seat 41. One end of the rotating rod 42 is inserted into the injector 1 and fixedly connected to the dredging rod 44, and one end of the other rotating rod 42 is inserted into the injector 1 and fixedly connected to the flow control plate 43. Please refer to Figure 2 and Figure 3 By rotating the rotating rod 42 to drive the flow control plate 43 to rotate in the ejector 1, the rotation angle of the flow control plate 43 can be adjusted. In this embodiment, the flow control plate 43 actually plays the role of a valve. Therefore, after the flow control plate 43 rotates, the flow rate of the semi-solid slurry can be adjusted, and the flow control ball head 22 can be used to comprehensively control the flow rate and flow velocity of the semi-solid slurry.

[0027] See also Figure 2 The flow controller 2 is rotated to make the ball seat 21 drive the flow control ball head 22 to move axially along the flow controller 2 to adjust the position of the flow control ball head 22 in the ejector 1, thereby adjusting the ejection speed of the slurry in the ejector 1. Specifically,

[0028] A. When the flow control ball head 22 does not enter the area below the axial centerline of the connection port 3, it means that the flow control ball head 22 does not occupy too much flow channel position of the ejector 1. The flow channel of the ejector 1 is large, so the flow rate of the semi-solid slurry passing through the interlayer between the flow control ball head 22 and the ejector 1 is small. Therefore, the injection speed of the semi-solid slurry ejected from the discharge port 12 is low, the injection flow rate is large, but the injection distance is relatively short;

[0029] B. When the flow control ball head 22 enters the area below the axial center line of the connecting port 3, it means that the flow control ball head 22 occupies more flow channel position of the injector 1. The flow channel of the injector 1 is small, so the flow rate of the semi-solid slurry passing through the interlayer between the flow control ball head 22 and the injector 1 is faster. Therefore, the injection speed of the semi-solid slurry ejected from the discharge port 12 is higher, the injection flow rate is smaller, but the injection distance is relatively far.

[0030] Therefore, the flow controller 2 can be moved according to the use requirements to adjust the injection speed of the semi-solid slurry at the discharge port 12. If the entire equipment is far away from the mold cavity, method B can be used to feed the material into the mold cavity. Otherwise, method A can be used to feed the material into the mold cavity.

[0031] As other embodiments of the utility model: one end of the ejector 1 is fixedly connected to a feed port 11, the end of the ejector 1 away from the feed port 11 is fixedly connected to a discharge port 12, the end of the feed port 11 away from the ejector 1 is fixedly connected to a connection port 3, the outer side of the connection port 3 is fixedly connected to a spring sheet 31, and one side of the spring sheet 31 is screwed with a fastening port 5.

[0032] See also Figure 1 and Figure 2 A connection port 3 is fixedly connected to one end of the feed port 11, and the connection port 3 can be connected to the semi-solid slurry pool. The slurry in the slurry pool is output from the discharge port 12 after passing through the connection port 3, the feed port 11 and the ejector 1, and the semi-solid material in the slurry pool is transferred to the mold cavity. The connection port 3 is a detachable structure, and can be easily disassembled when the ejector 1 and the connection port 3 are cleaned, thereby improving the cleaning efficiency.

[0033] Also, see Figure 4 The spring piece 31 is made of spring steel with a slope, and the outer circumference of the spring steel is engraved with threads, and the inner circle of the fastening port 5 is also engraved with threads. Therefore, when the fastening port 5 is screwed with the spring piece 31, the connecting port 3 and the slurry pool interface in contact with the connecting port 3 can be squeezed and fixed by the extrusion of the spring piece 31, and the fixing operation is convenient and the fixing effect is good.

[0034] As other embodiments of the utility model: the interference device 4 includes a mounting seat 41, a rotating rod 42 and a flow control plate 43, the mounting seat 41 is fixedly connected to the injector 1, and the rotating rod 42 is provided with two groups and both are screwed together with the mounting seat 41, one end of one rotating rod 42 is inserted into the injector 1 and fixedly connected to the dredging rod 44, and one end of the other rotating rod 42 is inserted into the injector 1 and fixedly connected to the flow control plate 43.

[0035] See also Figure 2 and Figure 3 When the rotating rod 42 drives the unblocking rod 44 to move in the ejector 1, the area between the connecting port 3 and the flow controller 2 that cannot be opened for cleaning can be stirred and cleaned. Specifically, the unblocking rod 44 can be stirred and cleaned after the semi-solid slurry is ejected and before the ejector 1 is cooled, so as to prevent the semi-solid slurry from being completely blocked due to cooling due to excessively low temperature.

[0036] At the same time, the rotation of the flow control plate 43 driven by the rotating rod 42 can change the spatial angle between the flow control plate 43 and the ejector 1. Therefore, after the flow control plate 43 rotates, the flow rate of the semi-solid slurry can be adjusted, and the flow control ball head 22 can be used to comprehensively control the flow rate and flow velocity of the semi-solid slurry.

[0037] As another embodiment of the utility model: one end of the flow controller 2 is fixedly connected to a ball seat 21 , and the end of the ball seat 21 away from the flow controller 2 is connected to a flow control ball head 22 .

[0038] See also Figure 2 and Figure 5 The ball seat 21 is screwed together with the ejector 1, and the height of the flow control ball head 22 can be adjusted after the ball seat 21 is screwed together with the ejector 1. The flow control ball head 22 is a hemispherical structure, and a step that can move with the ball seat 21 is designed at the position where it is connected to the ball seat 21. Therefore, during the flow of semi-solid slurry, the rotation of the flow control ball head 22 can avoid the problem of the semi-solid slurry getting stuck and unable to flow, thereby improving the flow efficiency of the semi-solid slurry.

[0039] As other embodiments of the present utility model: the threaded parts connecting the ball seat 21 and the ejector 1, and the threaded parts connecting the rotating rod 42 and the ejector 1 are all processed by high-precision machining.

[0040] The threaded parts connecting the ball seat 21 and the ejector 1, and the rotating rod 42 and the ejector 1 are high-precision machined to improve the sealing performance between the ball seat 21 and the ejector 1, and the rotating rod 42 and the ejector 1, thereby avoiding leakage.

[0041] The working principle of the utility model is: by rotating the flow controller 2, the ball seat 21 drives the flow control ball head 22 to move axially along the flow controller 2, and the position of the flow control ball head 22 in the injection device 1 can be adjusted, thereby adjusting the injection speed of the slurry in the injection device 1. Specifically,

[0042] A. When the flow control ball head 22 does not enter the area below the axial centerline of the connection port 3, it means that the flow control ball head 22 does not occupy too much flow channel position of the ejector 1. The flow channel of the ejector 1 is large, so the flow rate of the semi-solid slurry passing through the interlayer between the flow control ball head 22 and the ejector 1 is small. Therefore, the injection speed of the semi-solid slurry ejected from the discharge port 12 is low, the injection flow rate is large, but the injection distance is relatively short;

[0043] B. When the flow control ball head 22 enters the area below the axial center line of the connecting port 3, it means that the flow control ball head 22 occupies more flow channel position of the injector 1. The flow channel of the injector 1 is small, so the flow rate of the semi-solid slurry passing through the interlayer between the flow control ball head 22 and the injector 1 is faster. Therefore, the injection speed of the semi-solid slurry ejected from the discharge port 12 is higher, the injection flow rate is smaller, but the injection distance is relatively far.

[0044] Therefore, the flow controller 2 can be moved according to the use requirements to adjust the injection speed of the semi-solid slurry at the discharge port 12. If the entire device is far away from the mold cavity, method B can be used to feed the material into the mold cavity. Otherwise, method A can be used to feed the material into the mold cavity.

[0045] At the same time, by fixing a connection port 3 at one end of the feed port 11, the connection port 3 can be connected to the semi-solid slurry pool, and the slurry in the slurry pool is output from the discharge port 12 after passing through the connection port 3, the feed port 11 and the ejector 1, so that the semi-solid material in the slurry pool is transferred to the mold cavity, and the connection port 3 is a detachable structure, which can be conveniently disassembled when the ejector 1 and the connection port 3 are cleaned, thereby improving the cleaning efficiency;

[0046] Moreover, when the rotating rod 42 drives the clearing rod 44 to move in the ejector 1, the area between the connecting port 3 and the flow controller 2 that cannot be opened for cleaning can be stirred and cleaned. Specifically, the clearing rod 44 can be stirred and cleaned after the semi-solid slurry is ejected and before the ejector 1 is cooled, so as to prevent the semi-solid slurry from being completely blocked due to cooling due to excessively low temperature.

[0047] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
