As used in this description, the terms "may" and "can" include any one of, or all of, the possible combinations of the aspects described.

[0036] Some embodiments of the present application are described in detail. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] Embodiments

[0038] Referring to Figure 1 The present embodiment provides a die casting equipment 100, which can be a low-pressure die casting equipment.

[0039] During die casting, low pressure (e.g. 0.06-0.15 MPa) is applied on the surface of the molten metal by introducing compressed air, so that the metal slurry rises to fill the cavity of the mold, and a solidification control casting method is used.

[0040] The die casting equipment 100 in the present embodiment includes a mechanism table 10, a mold 20 and a slurry pool 40.

[0041] Referring to Figure 2 and Figure 3 The mechanism table 10 includes a lower loading table 11 and an upper loading table 12. The slurry pool 40 and the mold 20 are respectively located between the upper loading table 12 and the lower loading table 11.

[0042] The mold 20 includes an upper mold 22 and a lower mold 21, and the upper mold 22 and the lower mold 21 define a cavity Q1 therebetween. The shape of the cavity Q1 is consistent with the product to be formed. The upper mold 22 is connected to the side of the upper loading table 12 facing the lower loading table 11, and can be fixedly connected to the upper loading table 12 by locking members such as locking screws.

[0043] The slurry pool 40 has a containing cavity Q2 for containing the slurry 300 (e.g. molten metal slurry). The slurry pool 40 is arranged below the mold 20 and is fixedly supported on the lower loading platform 11. The containing cavity Q2 of the slurry pool 40 is in vertical communication with the cavity Q1 of the mold 20 above.

[0044] The die casting apparatus 100 can further be provided with a mold opening and closing driving member (e.g. a lifting cylinder) which is drivingly connected to the upper loading platform 12 and can drive the upper loading platform 12 to lift up and down, so as to drive the upper mold 22 to move close to or away from the lower mold 21, to realize mold closing or mold opening.

[0045] In the embodiment, the mold 20 is rotatably arranged. For example, in the embodiment, the mold 20 is fixed to the upper loading platform 12 which can be driven to rotate, so that the mold 20 can rotate with the upper loading platform 12. 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 flowability of the slurry 300, and facilitate the filling of the slurry 300 to all parts of the cavity Q1, so as to realize low-pressure die casting. For example, in the embodiment, the cavity Q1 is a flat cavity with a small vertical Z dimension, and has a large projected area in a plane perpendicular to the vertical Z. By rotating the mold 20, the slurry 300 is more easily filled to all parts of the cavity Q1.

[0046] In some embodiments, the slurry pool 40 is also rotatably arranged and can be synchronously rotated with the mold 20. In this way, the slurry pool 40 and the mold 20 are relatively stationary and do not relatively rotate to cause the slurry 300 to suck in air, which affects the quality of the die cast product.

[0047] By contrast, if the slurry pool 40 is stationary without rotating with the mechanism platform 10, the slurry 300 in the containing 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 can also stir the slurry 300 in the slurry pool 40 or in the communication passage T1 between the slurry pool 40 and the cavity Q1, so as to possibly suck in air and affect the molding quality.

[0048] In the embodiment, the upper loading platform 12 and the lower loading platform 11 are optionally configured to be able to rotate around a rotation axis Z1 parallel to the vertical Z (i.e. along the horizontal X direction). Figure 3The rotating shaft Z1 can pass through the center point of the cavity Q1. For example, the upper loading platform 12 and the lower loading platform 11 are synchronously driven to rotate by the same rotating driving device, so as to drive the slurry pool 40 and the mold 20 to synchronously rotate. In a specific arrangement, the rotating driving device can be directly connected to the lower loading platform 11, and the upper loading platform 12 and the lower loading platform 11 are engaged (for example, are clamped by a clamping structure) in a clamped state. In this way, when the rotating driving device drives the lower loading platform 11 to rotate, the upper loading platform 12 is synchronously driven to rotate, and the slurry pool 40 and the mold 20 are synchronously driven to rotate.

[0049] Continuing to refer to Figure 2 and Figure 3 In the embodiment, the lower mold 21 is provided with a sprue 23, and a communication channel T1 in the sprue 23 is communicated with the containing cavity Q2 at one end and with the cavity Q1 at the other end. In the embodiment, the sprue 23 is arranged along the vertical direction Z and has one liquid inlet K1 and one liquid outlet K2. In use, compressed air is introduced into the slurry pool 40 to press the slurry 300 in the slurry pool 40 along the communication channel T1 of the sprue 23 into the cavity Q1. The flow direction of the slurry can be seen from the arrow flow shown in Figure 3

[0050] Optionally, the central axis of the sprue 23 coincides with the rotating shaft Z1 of the mechanism platform 10. In this way, the slurry 300 in the sprue 23 is uniformly filled into the cavity Q1 in all directions.

[0051] In other embodiments, the sprue 23 can also have a plurality of liquid inlets K1 and / or a plurality of liquid outlets K2, which will be shown below.

[0052] Referring to Figures 3-5 In the embodiment, the die casting equipment 100 further comprises an electromagnetic device 30. The electromagnetic device 30 is arranged on the mold 20 and is used for magnetically attracting and guiding the slurry 300 in the cavity Q1.

[0053] In the embodiment, the electromagnetic device 30 has a magnetic member 31, which is rotatably matched to 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 rotates along the circumferential direction W2 shown in Figure 4 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 the opposite direction, and 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.

[0054] ​The magnetic member 31 comprises 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 column segment 31a on the side close to the cavity Q1. The magnetic portion 31b comprises a plurality of magnetic poles 311 distributed around the rotation axis of the column segment 31a. The magnetic poles 311 comprise a plurality of N poles 311n and a plurality of S poles 311s arranged in a 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 in the circumferential direction W2 to achieve cross adsorption, which facilitates the rapid and uniform pushing of the slurry 300 to all parts of the cavity Q1.

[0055] The column segment 31a and the magnetic portion 31b can be a one-piece magnet or a structure manufactured separately and then connected together, which is not limited here.

[0056] Referring to Figure 4 In this embodiment, the mold 20 is provided with a receiving groove C1 recessed from the surface of the mold 20 towards the direction close to the cavity Q1. For example, Figure 4 In this embodiment, the receiving groove C1 extends from the top surface of the upper mold 22 to the position close to the cavity Q1. The receiving groove C1 comprises a first groove segment C11 and a second groove segment C12, and the second groove segment C12 is located on the side of the first groove segment C11 close to the cavity Q1. The column segment 31a is rotatably fitted in the first groove segment C11, and the magnetic portion 31b is accommodated in the second groove segment C12 and can rotate in the second groove segment C12. In this way, the rotation of the magnetic member 31 is facilitated, and the magnetic portion 31b is closer to the cavity Q1, which facilitates the attraction of the slurry 300 in the cavity Q1 by the magnetic portion 31b, thereby facilitating the rapid filling of the slurry 300 into the cavity Q1.

[0057] In this embodiment, the magnetic member 31 corresponds to the position where the communication passage T1 communicates with the cavity Q1 in the vertical direction Z, i.e., the position of the liquid outlet K2 in the vertical direction Z. In this way, the magnetic member 31 can exert a magnetic force on the slurry 300 rising to the liquid outlet K2, and with the rotation of the magnetic member 31, the cross adsorption of each magnetic pole 311 can push the slurry 300 from the vicinity of the liquid outlet K2 to all directions, thereby accelerating the filling of the slurry 300 in the cavity Q1.

[0058] Referring to Figure 6 In this embodiment, the die casting equipment 100 further comprises a heating system 50. The heating system 50 is arranged on 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 facilitates the filling of the slurry 300 in the cavity Q1.

[0059] Optionally, the heating system 50 comprises heating elements 51 arranged in the upper mold 22 and the lower mold 21 respectively. The heating elements 51 can be heating pipes, heating wires, etc., which are not limited here.

[0060] The heating elements 51 can be multiple, and the multiple heating elements 51 are evenly distributed on the upper die 22 and the lower die 21 respectively, so as to improve the heating effect and the uniformity of heating. It should be noted that the heating elements 51 should avoid the positions of the accommodation groove C1, the cavity Q1 and the like.

[0061] Optionally, the electromagnetic device 30, the heating system 50 and the rotatable mechanism table 10 of the die casting equipment 100 in the embodiment can be retained only one or two, or can be simultaneously provided.

[0062] For example, the die casting equipment 100 in the embodiment only has the rotatable mechanism table 10, at this time, the slurry 300 can be filled into the cavity Q1 through the rotation filling of the mold 20 and / or the slurry pool 40.

[0063] For another example, the die casting equipment 100 in the embodiment only has the rotatable mechanism table 10 and the heating system 50, at this time, the slurry 300 can be filled into the cavity Q1 through the rotation filling and the heating to improve the fluidity.

[0064] For another example, the die casting equipment 100 in the embodiment only has the electromagnetic device 30 and the heating system 50, at this time, the slurry 300 can be filled into the cavity Q1 through the electromagnetic adsorption filling and the heating to improve the fluidity.

[0065] Figures 7-9 The die casting equipment 100a of the second embodiment of the application is shown.

[0066] The die casting equipment 100a is different from the die casting equipment 100 described above mainly in that the runner 23 of the mold 20 has one liquid inlet K1 and multiple liquid outlets K2, and each liquid outlet K2 is communicated with a different position of the accommodation cavity Q2. The runner 23 with the single liquid inlet K1 and the multiple liquid outlets K2 is beneficial to improve the speed of the slurry 300 flowing into the cavity Q1, and is especially suitable for the case that the cavity Q1 is large.

[0067] For the die casting equipment 100a with the multiple liquid outlets K2, the magnetic members 31 can be correspondingly multiple, and the multiple magnetic members 31 are respectively located at the positions corresponding to the multiple liquid outlets K2. In this way, for the slurry 300 at each liquid outlet K2, the magnetic member 31 can be used to realize the magnetic adsorption feeding, which is beneficial to improve the efficiency of the slurry 300 filling the cavity Q1.

[0068] Figures 10-12 The die casting equipment 100b of the third embodiment of the application is shown.

[0069] The die casting equipment 100b is mainly different from the aforementioned die casting equipment 100 in that the runner 23 of the mold 20 has multiple liquid inlets K1 and multiple liquid outlets K2, each liquid inlet K1 is respectively communicated with different positions of the accommodating cavity Q2 of the slurry pool 40, and each liquid outlet K2 is respectively communicated with different positions of the accommodating cavity Q2. The runner 23 with multiple liquid inlets K1 and multiple liquid outlets K2 is beneficial to improve the speed of the slurry 300 flowing out of the slurry pool 40 and the speed of the slurry 300 flowing into the cavity Q1, and is beneficial to the slurry 300 filling into the cavity Q1 at a very fast speed.

[0070] For the die casting equipment 100b with multiple liquid outlets K2, multiple magnetic members 31 are correspondingly arranged, and the multiple magnetic members 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 attracted and fed by the magnetic member 31, which is beneficial to improve the efficiency of the slurry 300 filling into the cavity Q1.

[0071] Figures 13-15 The die casting equipment 100c of the fourth embodiment of the present application is shown.

[0072] The die casting equipment 100c is mainly different from the aforementioned die casting equipment 100 in that the runner 23 of the mold 20 has a single liquid inlet K1 and multiple liquid outlets K2, and each liquid inlet K1 is respectively communicated with different positions of the accommodating cavity Q2 of the slurry pool 40. The runner 23 with multiple liquid inlets K1 and a single liquid outlet K2 is beneficial to improve the speed of the slurry 300 flowing out of the slurry pool 40 and the speed of the slurry 300 flowing into the cavity Q1.

[0073] It should be noted that the above scheme is a feeding mode of the lower mold 21, and in other embodiments, the feeding mode of the upper mold 22 can also be adjusted. That is, the slurry pool 40 is communicated with the cavity Q1 through the upper mold 22. At this time, the corresponding components are adjusted in the direction.

[0074] The embodiments of the present application also provide a die casting method based on the aforementioned die casting equipment 100, 100a, 100b, 100c.

[0075] The die casting method comprises: pressing the slurry 300 in the accommodating cavity Q2 into the cavity Q1, and rotating the slurry pool 40 and the mold 20 when the slurry 300 is injected into the cavity Q1; wherein the slurry pool 40 and the mold 20 are synchronously rotated or non-synchronously rotated.

[0076] At the same time, for the case where the electromagnetic device 30 is arranged, the electromagnetic device 30 can also be started to promote the filling of the slurry 300 into the cavity Q1. For the case where the heating system 50 is arranged, the heating system 50 can also be started to provide the temperature of the slurry 300, so as to improve the fluidity of the slurry 300 and facilitate the filling of the slurry 300 into the cavity Q1.

[0077] In this embodiment, the die-casting equipment 100, 100a, 100b, 100c and the die-casting method promote the filling of slurry 300 into cavity Q1 by means of centrifugal force from the rotation of mold 20 and / or slurry pool 40, adsorption effect of electromagnetic device 30, and heating system 50 to improve fluidity. This facilitates the increase in the filling speed and quality of slurry 300 into cavity Q1, enabling low-pressure die casting, reducing equipment weight and cost, lowering manufacturing costs and difficulty, and improving product quality and reducing scrap rate.

[0078] By combining different processes such as the rotation of the mold 20 and / or the slurry tank 40, the adsorption effect of the electromagnetic device 30, and the heating system 50, a multi-purpose machine can be achieved, suitable for processing and manufacturing large, medium, small, and various complex parts. An example will be provided below.

[0079] For example, in one die-casting process, die-casting is achieved solely by rotating the mechanism platform 10. The die-casting process is as follows: the mold 20 closes, the mechanism platform 10 drives the mold 20 and the slurry pool 40 to rotate synchronously, the slurry 300 is injected into the cavity Q1 under low pressure, and after the injection is completed, the mechanism platform 10 stops rotating, and the die-casting is completed.

[0080] For example, in another die-casting process, die-casting is achieved solely by rotating the electromagnetic device 30. The die-casting process in this case is as follows: the mold 20 is closed, the electromagnetic device 30 is turned on, the slurry 300 is injected into the cavity Q1 under low pressure, and after the injection is completed, the electromagnetic device 30 is turned off, and the die-casting is completed.

[0081] For example, in another die-casting process, the mechanism 10 grips and the electromagnetic device 30 rotates simultaneously. The die-casting process in this case is as follows: the mold 20 closes, the electromagnetic device 30 is turned on and the mechanism 10 rotates, the slurry 300 is injected into the cavity Q1 under low pressure, after the injection is completed, the mechanism 10 stops rotating and the electromagnetic device 30 is turned off, and the die-casting is completed.

[0082] In the above process, the heating system 50 can be activated as needed to control the temperature of the slurry 300, so as to ensure that the slurry 300 maintains a suitable temperature and fluidity during the die casting process.

[0083] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
