[0041] The die-casting device in the related art uses a spring to provide the ejection force.

[0043] By providing a controllable driving member capable of driving the ejection assembly to move stably along the first direction, the die casting can be smoothly demoulded, thereby facilitating the improvement of the reliability of the die casting device.

[0044] The die-casting device provided in the embodiment of the present application can be applied to forming die-casting parts of any specifications. As an example, the die-casting device provided in the embodiment of the present application can be applied to ultra-large integrated die-casting parts.

[0045] See also Figure 1 and Figure 2 According to an embodiment of the present application, a die-casting device is provided, comprising a mold base 10, an ejection assembly 20, and a controllable drive member 30. The mold base 10 has a connecting hole 101 extending along a first direction X. The ejection assembly 20 is arranged on one side of the mold base 10 along the first direction X. The ejection assembly 20 includes a top plate 21 and an ejection member 22. One end of the ejection member 22 along the first direction X is connected to the top plate 21, and the other end can extend into the connecting hole 101 and be clearance-matched with the connecting hole 101. The controllable drive member 30 is arranged on the mold base 10 and connected to the ejection assembly 20. The controllable drive member 30 is configured to drive the ejection assembly 20 to move along the first direction X.

[0046] The mold base 10 is used to mold the die-casting part aa. Specifically, the mold base 10 has a molding cavity, and the die-casting part aa is molded in the molding cavity. The connecting hole 101 is connected to the molding cavity, so that the ejector 22 can extend into the molding cavity through the connecting hole 101 to eject the die-casting part aa out of the molding cavity.

[0047] The top plate 21 is disposed on one side of the mold base 10 along the first direction X. Specifically, the top plate 21 is disposed on one side of the communication hole 101 along the first direction X. The top plate 21 is used to install the ejector 22 .

[0048] The ejector 22 is connected to one side of the top plate 21 facing the communicating hole 101 along the first direction X, and can extend into the communicating hole 101 along the first direction X to eject the die casting aa on the other side of the communicating hole 101 along the first direction X.

[0049] The ejection assembly 20 is movably connected to the mold base 10 through a controllable drive member 30. The controllable drive member 30 is used to provide a stable driving force to the ejection assembly 20 along the first direction X, thereby ensuring the stability of the ejection assembly 20 moving along the first direction X, thereby ensuring the stability of the ejection member 22 in the process of ejecting the die-casting aa, and further helping to ensure the molding quality of the die-casting aa.

[0050] Illustratively, the controllable driving member 30 is connected to the top plate 21 and is used to drive the top plate 21 to move along the first direction X. The top plate 21 transmits the driving force provided by the controllable driving member 30 to the ejecting member 22 so that the ejecting member 22 moves accordingly.

[0051] Some embodiments of the present application provide a die-casting device, which includes a mold base 10, an ejection assembly 20 and a controllable drive member 30. The mold base 10 is used for molding the die-casting part aa. The controllable drive member 30 is connected to the ejection assembly 20 to drive it to move along the first direction X, thereby enabling the ejection member 22 to move along the first direction X in the connecting hole 101 to push against the die-casting part aa located on the other side of the connecting hole 101. The controllable drive member 30 can provide a stable driving force to ensure smooth demolding of the die-casting part aa, thereby improving the reliability of the die-casting device.

[0052] Optionally, the mold base 10 may include a fixed mold base 11 and a movable mold base, the fixed mold base 11 and the movable mold base are arranged relative to each other along the first direction X and enclose a molding cavity to form a molded die-casting part aa, and the controllable drive component 30 can be connected to either the fixed mold base 11 or the movable mold base.

[0053] The shape of the top plate 21 may include but is not limited to any one of a circle, a rectangle, a trapezoid, and a polygon.

[0054] Optionally, the controllable driving member 30 may be connected to the top plate 21 , and of course, may also be connected to the ejecting member 22 .

[0055] In some embodiments, the controllable driving member 30 can be directly connected to the top plate 21, which helps to reduce assembly time and cost.

[0056] In other embodiments, the controllable driving member 30 is connected to the top plate 21 via an adapter frame, so that the position of the controllable driving member 30 relative to the top plate 21 is adjustable, which helps to improve the flexibility of use.

[0057] In some embodiments, the controllable driving member 30 may be connected to a side of the top plate 21 along the first direction X facing away from the communicating hole 101 .

[0058] In other embodiments, the controllable driving member 30 may be connected to one side of the top plate 21 along its own extension direction, wherein the extension direction of the top plate 21 intersects with the first direction X.

[0059] Optionally, the number of controllable driving members 30 can be set to one, two, or more.

[0060] As an example, the controllable driving member 30 is configured to drive the ejection assembly 20 to move along the first direction X toward the communicating hole 101 , so that the ejection member 22 moves toward the die casting aa in the communicating hole 101 and ejects it.

[0061] Furthermore, the controllable driving member 30 can also be configured to drive the ejection assembly 20 to move along the first direction X away from the communicating hole 101 , so as to reset the ejection assembly 20 and facilitate the next demoulding operation.

[0062] The controllable driving component 30 can drive the top plate 21 to reciprocate along the first direction X, that is, the controllable driving component 30 can drive the top plate 21 to move along the first direction X toward the connecting hole 101 to eject the die-casting part aa out of the mold base 10; after the die-casting part aa is ejected from the mold base 10, the controllable driving component 30 can drive the top plate 21 to move along the first direction X away from the connecting hole 101, so as to facilitate the mold base 10 to produce the die-casting part aa next time.

[0063] In some embodiments, the mold base 10 is provided with a plurality of communicating holes 101 , and accordingly, the number of the ejection members 22 can be set to be multiple. Optionally, one ejection member 22 is provided corresponding to one communicating hole 101 .

[0064] In some embodiments, the mold base 10 is provided with a plurality of communicating holes 101 at equal intervals, and a plurality of ejectors 22 are distributed at equal intervals on the top plate 21, which helps to ensure stable load transfer between the ejectors 22 and the die casting aa.

[0065] In some embodiments, at least a portion of the ejector 22 can always be located within the communicating hole 101, which is beneficial to improving the ejection efficiency; in other embodiments, when there is no need to eject the die-casting aa, the ejector 22 is located outside the communicating hole 101. When there is a need to eject, the controllable drive member 30 drives the ejector plate 21 to move so that the ejector 22 extends into the communicating hole 101.

[0066] In some optional embodiments, the controllable driving member 30 includes at least one of a telescopic cylinder, a crank slider mechanism, and a cam mechanism.

[0067] The controllable drive element 30 may include a telescopic cylinder, which may include a cylinder tube, a piston, and a piston rod. The cylinder tube contains the piston and piston rod, which convert air pressure into mechanical motion. The piston rod is connected to the piston to enable telescopic motion driven by the piston. For example, the top plate 21 may be connected to the piston rod to move therewith in the first direction X. The telescopic cylinder may also include a sealing element between the piston and the piston rod to prevent air leakage and contamination.

[0068] Optionally, the telescopic cylinder can be set as any one of an oil cylinder, a telescopic hydraulic cylinder, and an electric telescopic cylinder. Setting the controllable drive member 30 as a telescopic cylinder has good sealing performance and a load-bearing cavity, thereby helping to improve the reliability of the die-casting device.

[0069] The controllable driving member 30 may also include a crank slider mechanism, which may include a crank, a crank slider and a connecting rod. Specifically, the crank rotates to drive the connecting rod to drive the crank slider to perform linear reciprocating motion. The top plate 21 can be connected to the crank slider to move along the first direction X accordingly.

[0070] The controllable driving member 30 is configured as a crank slider mechanism, which is easy to design and manufacture and has high reliability, thereby helping to improve the reliability of the transport device.

[0071] The controllable driving member 30 may further include a cam mechanism, which may include a cam, a follower, and a frame. The cam has a contour line or a groove, and the follower contacts the contour line or the groove. The rotational motion of the cam can drive the transmission member to perform reciprocating linear motion. The frame is connected to the base and is used to support the follower to limit the follower and ensure that the follower can reciprocate along the first direction X. Exemplarily, the top plate 21 is connected to the side of the transmission member facing away from the cam along the first direction X.

[0072] The controllable driving member 30 is configured as a cam mechanism, which has a simple and compact structure and is easy to assemble, thereby helping to save the overall space occupied by the handling device.

[0073] The die-casting device provided in some embodiments of the present application, through the above-mentioned configuration, enables the die-casting device to use different controllable driving members 30 to meet the effectiveness of driving the top plate 21 to move along the first direction X, which is conducive to improving the flexibility of use of the die-casting device.

[0074] In some optional embodiments, the controllable driving member 30 may also be configured as a motor.

[0075] In some optional embodiments, the number of the controllable driving members 30 is set to two or more, and the two or more controllable driving members 30 are distributed at intervals along the circumference of the top plate 21.

[0076] The circumferential distribution of two or more controllable driving members 30 along the top plate 21 can be understood as the controllable driving members 30 can be arranged at the peripheral position of the top plate 21 along its own extension direction.

[0077] This arrangement helps to improve the stability of the controllable driving member 30 driving the top plate 21 to move along the first direction X, thereby helping to improve the stability of the die-casting device.

[0078] In some embodiments, two or more controllable driving members 30 are distributed at equal intervals to ensure that they can stably drive the top plate 21 to move.

[0079] As an example, the shape of the top plate 21 is set to be rectangular, the number of the controllable driving members 30 is set to four, and the four controllable driving members 30 are respectively arranged at the four top corners of the top plate 21 to ensure that the controllable driving members 30 stably drive the top plate 21.

[0080] Please also refer to Figures 1 to 3 In some optional embodiments, the die-casting device also includes a pipeline interface 40, each controllable driving component 30 includes a driving component 31 and a connecting pipe 32 connected between the driving component 31 and the pipeline interface 40, and each driving component 31 is connected to the ejection assembly 20.

[0081] Each driving component 31 may be connected to the top plate 21 .

[0082] The pipeline interface 40 is used to connect to an external power source to provide fluid to each driving component 31 through each connecting pipe 32 .

[0083] The connecting pipe 32 is connected between the driving component 31 and the pipeline interface 40 to pass the fluid provided by the external power source into the driving component 31, so that the driving component 31 has the ability to stably drive the top plate 21 to move. The fluid may include gas or liquid.

[0084] The die-casting device provided in some embodiments of the present application, through the above-mentioned arrangement, enables each driving component 31 to be connected to the pipeline interface 40 through an independent connecting pipe 32 to achieve individual control of the driving component 31, and can provide different sizes of driving force to different positions of the top plate 21 according to the size of the clamping force at different positions of the die-casting aa, so as to ensure the smooth demolding of the die-casting aa.

[0085] Furthermore, the external power source can output different pressures to each driving component 31, and the time of pressure output can be freely controlled to achieve stable demoulding of the die-casting part aa, which is conducive to improving the flexibility of use.

[0086] In some optional embodiments, the connecting tubes 32 are configured to transport liquid, and the lengths of each connecting tube 32 are the same.

[0087] The connecting pipe 32 is used for conveying liquid, wherein the external power source can be set as an oil pump. By setting it in this way, the controllable driving component 30 can be more stable and reliable.

[0088] By setting the length of each connecting pipe 32 to be the same, the distance from each driving component 31 to the pipeline interface 40 is the same, which can ensure that the time for the liquid to flow to each driving component 31 is the same, facilitates the control of each driving component 31, and also helps to ensure the driving stability of the driving component 31, thereby helping to improve the stability of the die-casting device.

[0089] Please also refer to Figures 1 to 4 In some optional embodiments, the die-casting apparatus further includes a control assembly and a detection assembly 60. The detection assembly 60 is electrically connected to the control assembly, and at least a portion of the detection assembly 60 is connected to the ejection assembly 20. The ejection assembly 20 is configured to detect the distance the ejection assembly 20 moves along the first direction X and send a control signal to the control assembly. The control assembly is configured to receive the control signal and control the controllable drive member 30 to stop operating.

[0090] The electrical connection of the detection component 60 to the control assembly can be understood as the electrical signal of the detection component 60 being connected to the control assembly.

[0091] The detection assembly 60 is used to detect the distance the ejection assembly 20 has moved in the first direction X. When the distance moved by the ejection assembly 20 in the first direction X reaches a preset distance value, the detection assembly 60 sends a control signal to the control assembly. The preset distance value is the distance the ejection assembly 20 has moved in the first direction X when the die-casting aa is ejected from the mold base 10. The specific value can be set as needed.

[0092] The control assembly is used to receive the control signal and control the controllable driving member 30 to stop running, and the ejection assembly 20 then stops moving.

[0093] For example, a valve may be provided on the connecting pipe 32 communicating between the pipeline interface 40 and the controllable driving member 30 , and the control assembly may drive the valve to close so that the controllable driving member 30 stops driving.

[0094] The die-casting device provided in some embodiments of the present application is configured in the above manner to detect whether the top plate 21 has moved to a preset position, so as to monitor the driving time and driving process of the controllable driving member 30, thereby ensuring that the ejector 22 can accurately eject the die-casting part aa.

[0095] Illustratively, at least a portion of the detection assembly 60 is connected to the top plate 21 , and it may be connected to the top plate 21 directly or through an adapter frame.

[0096] Optionally, the detection component 60 may be entirely connected to the top plate 21 . Of course, a portion of the detection component 60 may be connected to the top plate 21 , and the other portion may be connected to the mold base 10 .

[0097] Optionally, the detection component 60 may include any one of an infrared detector and a position sensor.

[0098] like Figure 4 As shown, in some optional embodiments, the number of detection components 60 is set to two or more, and the detection components 60 and the controllable driving members 30 are set one to one.

[0099] The one-to-one setting of the detection component 60 and the controllable drive component 30 can be understood as that at least a portion of each detection component 60 is connected to the top plate 21 near the position near the corresponding controllable drive component 30. Due to the size of the clamping force at different positions of the die-casting aa, the size of the driving force provided by each controllable drive component 30 may also be different, and each controllable drive component 30 can be monitored by a detection component 60.

[0100] For example, in a specific implementation process, the ejector 22 corresponding to the top plate 21 at a certain position has ejected the die-cast part aa, that is, the top plate 21 at this position has moved a preset distance, and the detection component 60 connected near the top plate 21 at this position can send a control signal to the control assembly, and the control assembly can control the controllable driving component 30 near the top plate 21 at this position to stop running, while the controllable driving components 30 at other positions operate normally.

[0101] By setting in this manner, it is possible to individually monitor each controllable drive member 30 , further improving the reliability of the die-casting device.

[0102] In some embodiments, the control assembly has a signal interface 51 , and each detection component 60 includes a detection member 61 and a signal line 62 electrically connected between the detection member 61 and the signal interface 51 . At least a portion of the detection member 61 is connected to the ejection assembly 20 .

[0103] The connecting wire is used to realize the electrical connection between the detection component 60 and the signal interface 51 to ensure the effectiveness of the electrical connection between the detection component 60 and the signal interface 51 .

[0104] By configuring in the above manner, each detection element 61 can transmit signals through a separate signal line 62 to achieve separate monitoring of each controllable driving element 30 , thereby better improving the reliability of the die-casting device.

[0105] Please continue reading Figure 2 and Figure 4In some embodiments, the detection member 61 includes a signal switch 611 and a trigger member 612. The signal switch 611 is connected to the ejection assembly 20 and is electrically connected to the control assembly. The trigger member 612 is arranged on the mold base 10. The trigger member 612 can abut against the signal switch 611 so that the signal switch 611 sends a control signal to the control assembly.

[0106] The signal switch 611 may be connected to the top plate 21 .

[0107] The controllable driving member 30 drives the top plate 21 to move along the first direction X toward the communicating hole 101 , and the signal switch 611 moves synchronously with the top plate 21 . When the signal switch 611 is not in contact with the trigger member 612 , the signal switch 611 is in a closed state.

[0108] When the signal switch 611 moves a predetermined distance along the first direction X of the top plate 21 toward the connecting hole 101, the signal switch 611 is abutted against the trigger member 612. At this time, the signal switch 611 is in the open state and sends a control signal to the control assembly. The control assembly controls the controllable driving member 30 to stop driving, the top plate 21 no longer moves, and the die-casting part aa has been ejected.

[0109] The die-casting device provided in some embodiments of the present application realizes the control of the driving time of the controllable driving member 30 through the above-mentioned method, and can detect whether the ejection assembly 20 is moved into position to smoothly eject the die-casting part aa. It has a simple structure, is easy to assemble, and is conducive to ensuring effectiveness.

[0110] See also Figure 1 and Figure 2 In some optional embodiments, the die-casting device further includes a guide column 70, and the mold base 10 further has a guide hole 102 extending along the first direction X and spaced apart from the connecting hole 101. One end of the guide column 70 along the first direction X is connected to the top plate 21, and the other end is arranged in the guide hole 102 and is gap-fitted with the guide hole 102.

[0111] The guide post 70 is disposed in the guide hole 102 and moves along the first direction X in the guide hole 102 as the top plate 21 moves.

[0112] The guide post 70 is always arranged in the guide hole 102, and can guide the movement of the ejection assembly 20 to ensure that the ejection member 22 is smoothly extended into the connecting hole 101. It can also ensure the clearance fit between the ejection member 22 and the connecting hole 101 to prevent excessive friction between it and the hole wall of the connecting hole 101, so as to ensure smooth demolding of the die-casting part aa, which is beneficial to improving the stability of the die-casting device.

[0113] In some optional embodiments, the radial dimension of the guide column 70 is greater than the radial dimension of the ejector 22 so that it can better provide a guiding effect.

[0114] In some optional embodiments, one end of the guide post 70 facing away from the top plate 21 along the first direction X is disposed close to the movable mold base relative to one end of the ejector 22 facing away from the top plate 21 along the first direction X.

[0115] Through the above arrangement, after the die-casting aa is produced, the controllable driving member 30 drives the top plate 21 to move along the first direction X toward the movable mold base, so that the guide column 70 and the ejector 22 both move with the top plate 21. During the movement of the two, the guide column 70 will first contact the movable mold base and eject it, so that the mold base 10 is opened, and then the ejector 22 will contact the die-casting aa and eject it, so that it is separated from the movable mold base, so that the die-casting aa can be smoothly demolded. There is no need to set up other driving mechanisms to control the mold base 10 to open the mold, which is convenient for operation, helps to improve operating efficiency, and helps to reduce costs.

[0116] In some optional embodiments, the number of the guide posts 70 is set to two or more, and the two or more guide posts 70 are distributed at intervals along the circumference of the top plate 21 and are arranged around the ejector 22 .

[0117] The arrangement of two or more guide posts 70 around the ejector 22 can be understood as follows: in the first direction X, the orthographic projection of the ejector 22 falls between the connecting lines formed by the orthographic projections of the two or more guide posts 70. This arrangement makes the layout reasonable, facilitates processing and manufacturing, and helps to further ensure the stability of the die-casting device.

[0118] As an example, the number of guide posts 70 can be set to four, and they are respectively arranged at the four top corners of the top plate 21 along the circumferential direction, so as to better guide the movement of the top plate 21, thereby better ensuring the stability of the die-casting device.

[0119] In some optional embodiments, the mold base 10 includes a fixed mold base 11 and a movable mold base, the movable mold base is arranged on one side of the fixed mold base 11 along the first direction X, the fixed mold base 11 has a connecting hole 101 and a guide hole 102, the ejection assembly 20 is arranged on the side of the fixed mold base 11 along the first direction X facing away from the movable mold base, the controllable driving member 30 is arranged on the fixed mold base 11, and the movable mold base is configured to push against the guide column 70 so that the guide column 70 moves along the first direction X toward the fixed mold base 11.

[0120] After the die-casting aa is demolded, the fixed mold base 11 and the movable mold base are molded together, and the guide column 70 can be pushed by the movable mold base to move along the first direction X toward the fixed mold base 11, thereby driving the ejector plate 21 and the ejector 22 to move to the initial position, so as to facilitate the next production of the die-casting aa.

[0121] By arranging in the above manner, the ejection assembly 20 can be reset by mechanical transmission, which is easy to operate and helps to reduce costs.

[0122] In some optional embodiments, the ejection assembly 20 further includes a limiting plate detachably connected to the top plate 21 , and a portion of the ejection member 22 is clamped between the limiting plate and the top plate 21 along the first direction X.

[0123] The limiting plate can be detachably connected to the top plate 21 by fasteners such as bolts, studs, and bolts, so that part of the ejector 22 is clamped between the limiting plate and the top plate 21, which is beneficial to ensure the connection strength between the ejector 22 and the top plate 21, thereby improving the reliability of the die-casting device.

[0124] Specifically, the ejecting member 22 may include an adapter plate and an ejecting body that are connected to each other. The ejecting body is provided in multiple numbers and extends along the first direction X. The ejecting body can extend into the connecting hole 101 to fit with the connecting hole 101. The ejecting body is connected to the top plate 21 through the adapter plate. The limiting plate is provided on the side of the adapter plate that is away from the top plate along the first direction X to clamp part of the adapter plate between the limiting plate and the top plate 21 along the first direction X.

[0125] like Figure 2 As shown, in some optional embodiments, the die-casting device further includes a fixing plate 80 , and the controllable driving member 30 is connected to the mold base 10 via the fixing plate 80 .

[0126] The fixing plate 80 can be detachably connected to the mold base 10 by fasteners such as bolts, studs, and bolts, wherein the fixing plate 80 can be detachably connected to the fixed mold base 11 by fasteners such as bolts, studs, and bolts.

[0127] The controllable driving member 30 can be detachably connected to the fixing plate 80 by fasteners such as bolts, studs, and nails.

[0128] This arrangement helps to improve the flexibility of the position of the controllable driving member 30 on the mold base 10, and does not require modification of the mold base 10, making it easier to manufacture and assemble.
