DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a centered element. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0037] Example See also Figure 1 , this embodiment provides a die-casting device 100, which may specifically be a low-pressure die-casting device.

[0038] During die casting, compressed air is introduced to apply low pressure (such as 0.06-0.15MPa) on the surface of the molten metal, causing the metal slurry to rise and fill the cavity of the mold, and controlling the solidification.

[0039] In this embodiment, the die-casting equipment 100 includes a mechanism platform 10 , a mold 20 and a slurry pool 40 .

[0040] See also Figure 2 and Figure 3 The mechanism platform 10 includes a downloading platform 11 and an uploading platform 12. The slurry pool 40 and the mold 20 are respectively located between the uploading platform 12 and the downloading platform 11.

[0041] The mold 20 includes an upper mold 22 and a lower mold 21, and a cavity Q1 is defined between the upper mold 22 and the lower mold 21. The shape of the cavity Q1 is consistent with the product to be molded. The upper mold 22 is connected to the side of the upper platform 12 facing the lower platform 11, for example, it can be fixedly connected to the upper platform 12 by a locking member such as a locking screw.

[0042] The slurry pool 40 has a receiving cavity Q2 for receiving slurry 300 (such as molten metal slurry). The slurry pool 40 is disposed below the mold 20 and supported and fixed on the unloading platform 11. The receiving cavity Q2 of the slurry pool 40 is connected to the mold cavity Q1 of the upper mold 20 along the vertical direction Z.

[0043] The die-casting equipment 100 may also be provided with a mold opening and closing driving member (such as a lifting cylinder), which is connected to the upper platform 12 in a transmission manner and can drive the upper platform 12 to rise and fall, so as to drive the upper mold 22 to approach or move away from the lower mold 21 to achieve mold closing or mold opening.

[0044] In the present embodiment, the mold 20 is rotatably arranged. For example, in the present embodiment, the mold 20 is fixed to an upper stage 12 that can be driven to rotate, so that the mold 20 can rotate as the upper stage 12 rotates. During the process of injecting the slurry 300 into the cavity Q1, the mold 20 can be rotated to reduce the die-casting resistance, improve the fluidity of the slurry 300, and facilitate the filling of the slurry 300 into various parts of the cavity Q1, thereby realizing low-pressure die-casting. For example, in the present embodiment, the cavity Q1 is a flat cavity with a small vertical Z dimension, and its projected area in a plane perpendicular to the vertical Z is large. By rotating the mold 20, the slurry 300 is more easily filled into various parts of the cavity Q1.

[0045] In some embodiments, the slurry pool 40 is also rotatably arranged and can rotate synchronously with the mold 20. In this way, the slurry pool 40 and the mold 20 are relatively stationary, and relative rotation does not occur to cause air to be sucked into the slurry 300, affecting the quality of the die-casting product.

[0046] In contrast, if the slurry pool 40 does not rotate with the mechanism table 10 but remains stationary, the slurry 300 in the receiving cavity Q2 of the slurry pool 40 is in a stationary state, and the stationary slurry 300 will have a certain suction resistance, which is not conducive to the slurry 300 entering the cavity Q1. At the same time, the rotation of the mold 20 relative to the slurry pool 40 may also stir the slurry 300 in the slurry pool 40 or in the connecting channel T1 between the slurry pool 40 and the cavity Q1, thereby inhaling air and affecting the molding quality.

[0047] In this embodiment, the upper loading platform 12 and the unloading platform 11 are optionally configured to be able to rotate around a rotation axis Z1 parallel to the vertical Z (i.e., along Figure 3The upper platform 12 and the lower platform 11 are synchronously rotated in the circumferential direction W1 shown in the figure. The rotation axis Z1 may pass through the center point of the cavity Q1. For example, the upper platform 12 and the lower platform 11 are synchronously driven to rotate by the same rotation drive device, thereby driving the slurry pool 40 and the mold 20 to rotate synchronously. In the specific setting, the rotation drive device may be directly connected to the lower platform 11, and in the mold closing state, the upper platform 12 and the lower platform 11 are engaged (such as mutually engaged through a snap-fit ​​structure). In this way, when the rotation drive device drives the lower platform 11 to rotate, it can drive the upper platform 12 to rotate synchronously, and then synchronously drive the slurry pool 40 and the mold 20 to rotate synchronously.

[0048] Continue to see Figure 2 and Figure 3 In this embodiment, the lower mold 21 is provided with a casting channel 23, and one end of the connecting channel T1 inside the casting channel 23 is connected to the accommodating cavity Q2, and the other end is connected to the mold cavity Q1. In this embodiment, the casting channel 23 is arranged along the vertical direction Z, and has a liquid inlet K1 and a liquid outlet K2. When in use, the slurry 300 in the slurry pool 40 is pressed into the mold cavity Q1 along the connecting channel T1 of the casting channel 23 by passing compressed air into the slurry pool 40. The flow direction of the slurry can be seen in FIG. Figure 3 The arrow flow is shown in FIG.

[0049] Optionally, the central axis of the sprue 23 coincides with the rotation axis Z1 of the mechanism platform 10. In this way, the slurry 300 in the sprue 23 is facilitated to be uniformly filled into the mold cavity Q1.

[0050] In other embodiments, the sprue 23 may also have a plurality of liquid inlets K1 and / or a plurality of liquid outlets K2, which will be described in detail below.

[0051] See also Figure 3-Figure 5 In this embodiment, the die-casting equipment 100 further includes an electromagnetic device 30. The electromagnetic device 30 is disposed in the mold 20 and is used to magnetically attract and guide the slurry 300 in the cavity Q1.

[0052] In this embodiment, the electromagnetic device 30 has a magnetic member 31, which is rotatably matched with the mold 20 and can be driven to rotate relative to the mold 20 so that the magnetic pole 311 of the magnetic member 31 is along the Figure 4 The circumferential direction W2 shown in the figure rotates to attract and drive the slurry 300 in the cavity Q1 to flow. The circumferential direction W2 and the circumferential direction W1 can be in the same direction or in opposite directions; the circumferential direction W2 and the circumferential direction W1 can surround the same axis or different axes. The magnetic member 31 can be driven by a rotating motor or other driving structure.

[0053] The magnetic member 31 includes a column segment 31a and a magnetic portion 31b. The column segment 31a is rotatably connected to the mold 20, and the magnetic portion 31b is connected to the side of the column segment 31a close to the cavity Q1. The magnetic portion 31b includes a plurality of magnetic poles 311, and the plurality of magnetic poles 311 are distributed around the rotation axis of the column segment 31a. The magnetic poles 311 include a plurality of N poles 311n and a plurality of S poles 311s, and the plurality of N poles 311n and the plurality of S poles 311s are cross-arranged along the circumferential direction. In this way, when the magnetic portion 31b rotates, the plurality of N poles 311n and the plurality of S poles 311s rotate along the circumferential direction W2 to achieve a cross-adsorption effect, which is conducive to quickly and evenly pushing the slurry 300 to various locations in the cavity Q1.

[0054] The column section 31a and the magnetic portion 31b may be an integrated magnet, or may be a structure that is manufactured separately and then connected together, which is not limited here.

[0055] Main references Figure 4 In this embodiment, the mold 20 is provided with a receiving groove C1, and the receiving groove C1 is recessed from the surface of the mold 20 toward the direction close to the cavity Q1. For example, Figure 4 In the embodiment, the receiving groove C1 extends downward from the top surface of the upper mold 22 to a position close to the mold cavity Q1. The receiving groove C1 includes a first groove section C11 and a second groove section C12, and the second groove section C12 is located on the side of the first groove section C11 close to the mold cavity Q1. The column section 31a is rotatably matched with the first groove section C11, and the magnetic part 31b is accommodated in the second groove section C12 and can rotate in the second groove section C12. In this way, it is convenient for the magnetic part 31 to rotate, and the magnetic part 31b can be closer to the mold cavity Q1, which is conducive to improving the attraction of the magnetic part 31b to the slurry 300 in the mold cavity Q1, thereby facilitating the slurry 300 to be quickly filled into the mold cavity Q1.

[0056] In this embodiment, the magnetic member 31 corresponds to the place where the connecting channel T1 is connected to the cavity Q1 along the vertical direction Z, that is, the magnetic member 31 corresponds to the liquid outlet K2 along the vertical direction Z. In this way, the magnetic member 31 can exert a magnetic force on the slurry 300 that rises to the liquid outlet K2, and as the magnetic member 31 rotates, the cross adsorption of each magnetic pole 311 can push the slurry 300 from the vicinity of the liquid outlet K2 to the surroundings, thereby accelerating the filling of the slurry 300 in the cavity Q1.

[0057] See also Figure 6 In this embodiment, the die casting device 100 further includes a heating system 50. The heating system 50 is disposed in the mold 20 and is used to heat the slurry 300 in the cavity Q1. By heating the slurry 300, the fluidity of the slurry 300 can be improved, which is beneficial to the filling of the slurry 300 in the cavity Q1.

[0058] Optionally, the heating system 50 includes heating elements 51 respectively disposed in the upper mold 22 and the lower mold 21. The heating element 51 can be a heating tube, a heating wire, etc., which is not limited here.

[0059] There can be multiple heating elements 51, and the multiple heating elements 51 are evenly distributed in the upper mold 22 and the lower mold 21 to improve the heating effect and heating uniformity. It should be noted that the heating element 51 should avoid the receiving groove C1, the cavity Q1 and other positions.

[0060] Optionally, the electromagnetic device 30 , the heating system 50 and the rotatable mechanism table 10 of the die-casting equipment 100 of the present embodiment may retain only one or two of them, or may have them simultaneously.

[0061] For example, the die-casting equipment 100 in this embodiment only has a rotatable mechanism table 10 . In this case, the slurry 300 can be quickly filled into the cavity Q1 by rotating the mold 20 and / or the slurry pool 40 .

[0062] For another example, the die-casting equipment 100 in this embodiment only has a rotatable mechanism table 10 and a heating system 50. At this time, the slurry 300 can be quickly filled into the mold cavity Q1 by rotating filling and heating to improve fluidity.

[0063] For another example, the die-casting equipment 100 in this embodiment only has the electromagnetic device 30 and the heating system 50. At this time, the slurry 300 can be quickly filled into the mold cavity Q1 by electromagnetic adsorption filling and heating to improve fluidity.

[0064] Figure 7-Figure 9 A die casting device 100a according to a second embodiment of the present application is shown.

[0065] The main difference between the die-casting device 100a and the aforementioned die-casting device 100 is that the casting channel 23 of the mold 20 has a liquid inlet K1 and multiple liquid outlets K2, and each liquid outlet K2 is connected to a different position of the accommodating cavity Q2. This casting channel 23 with a single liquid inlet K1 and multiple liquid outlets K2 is conducive to increasing the speed of the slurry 300 flowing into the cavity Q1, and is particularly suitable for the case where the cavity Q1 is large.

[0066] For the die-casting equipment 100a with multiple liquid outlets K2, multiple magnetic parts 31 can be provided accordingly, and the multiple magnetic parts 31 are respectively located at the corresponding multiple liquid outlets K2. In this way, the slurry 300 at each liquid outlet K2 can be fed by magnetic attraction through the magnetic part 31, which is beneficial to improve the efficiency of the slurry 300 filling the mold cavity Q1.

[0067] Figure 10-12 A die casting device 100b according to a third embodiment of the present application is shown.

[0068] The main difference between the die-casting device 100b and the aforementioned die-casting device 100 is that the casting channel 23 of the mold 20 has multiple liquid inlets K1 and multiple liquid outlets K2, each of which is connected to a different position of the accommodating cavity Q2 of the slurry pool 40, and each of which is connected to a different position of the accommodating cavity Q2. This casting channel 23 with multiple liquid inlets K1 and multiple liquid outlets K2 is conducive to increasing the speed at which the slurry 300 flows out of the slurry pool 40 and flows into the mold cavity Q1, and is conducive to the slurry 300 filling the mold cavity Q1 from the slurry pool 40 at a very fast speed.

[0069] For the die-casting equipment 100b with multiple liquid outlets K2, multiple magnetic parts 31 are correspondingly provided, and the multiple magnetic parts 31 are respectively located at the corresponding multiple liquid outlets K2. In this way, the slurry 300 at each liquid outlet K2 can be magnetically fed through the magnetic part 31, which is beneficial to improve the efficiency of the slurry 300 filling the mold cavity Q1.

[0070] Figure 13-Figure 15 A die casting device 100c according to a fourth embodiment of the present application is shown.

[0071] The main difference between the die-casting device 100c and the aforementioned die-casting device 100 is that the casting channel 23 of the mold 20 has a single liquid inlet K1 and multiple liquid outlets K2, and each liquid inlet K1 is respectively connected to a different position of the accommodating cavity Q2 of the slurry pool 40. This casting channel 23 with multiple liquid inlets K1 and a single liquid outlet K2 is conducive to increasing the speed at which the slurry 300 flows out of the slurry pool 40 and flows into the mold cavity Q1.

[0072] It should be noted that the above scheme is a method of feeding the lower mold 21. In other embodiments, it can also be adjusted to feed the upper mold 22. That is, the slurry pool 40 is connected to the cavity Q1 through the upper mold 22. At this time, the corresponding parts can be turned around.

[0073] The embodiment of the present application further provides a die-casting method, which is based on the aforementioned die-casting equipment 100, 100a, 100b, 100c.

[0074] The die-casting method includes pressing the slurry 300 in the receiving cavity Q2 into the mold cavity Q1, and rotating the slurry pool 40 and the mold 20 when injecting the slurry 300 into the mold cavity Q1; wherein the slurry pool 40 and the mold 20 rotate synchronously or asynchronously.

[0075] At the same time, in the case where the electromagnetic device 30 is configured, the electromagnetic device 30 can also be activated to promote the slurry 300 to be filled into the cavity Q1. In the case where the heating system 50 is configured, the heating system 50 can also be activated to provide the slurry 300 temperature to improve the fluidity of the slurry 300, which is conducive to the slurry 300 filling the cavity Q1.

[0076] The die-casting equipment 100, 100a, 100b, 100c and die-casting method in this embodiment promote the filling of the slurry 300 into the cavity Q1 by means of the centrifugal force of the rotation of the mold 20 and / or the slurry pool 40, the adsorption effect of the electromagnetic device 30, and the heating by the heating system 50 to increase fluidity, which is beneficial to improve the speed and filling quality of the slurry 300 into the cavity Q1, can achieve low-pressure die-casting, reduce equipment weight and equipment cost, reduce manufacturing cost and manufacturing difficulty, and improve product quality and reduce scrap rate.

[0077] By combining the rotation of the mold 20 and / or the slurry pool 40, the adsorption of the electromagnetic device 30, the heating system 50 and other different processes, a machine can be used for multiple purposes, and is suitable for processing and manufacturing large, medium, small and various complex parts. An exemplary introduction will be given below.

[0078] For example, in a die-casting process, die-casting is achieved only by rotating the mechanism table 10. The die-casting process at this time is as follows: the mold 20 is closed, the mechanism table 10 drives the mold 20 and the slurry pool 40 to rotate synchronously, the slurry 300 is injected into the cavity Q1 at low pressure, and after the injection is completed, the mechanism table 10 stops rotating, and the die-casting is completed.

[0079] For example, in another die-casting process, die-casting is achieved only by rotating the electromagnetic device 30. The die-casting process is as follows: the mold 20 is closed, the electromagnetic device 30 is turned on, the slurry 300 is injected into the cavity Q1 at low pressure, and after the injection is completed, the electromagnetic device 30 is turned off, and the die-casting is completed.

[0080] For another example, in another die-casting process, the mechanism table 10 selects and the electromagnetic device 30 rotates simultaneously. The die-casting process at this time is as follows: the mold 20 is closed, the electromagnetic device 30 is turned on and the mechanism table 10 rotates, the slurry 300 is injected into the cavity Q1 at low pressure, and after the injection is completed, the mechanism table 10 stops rotating and the electromagnetic device 30 is turned off, and the die-casting is completed.

[0081] In the above process, the heating system 50 can be started as needed to control the temperature of the slurry 300 to ensure that the slurry 300 maintains a suitable temperature and fluidity during the die-casting process.

[0082] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
