[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1-9 A multi-mold die-casting mechanism provided by an embodiment of the present invention includes a frame 1 and a material injection pipeline 2 of a die-casting machine (not shown in the figure), and also includes: a sleeve frame 3, a rotating frame 4, two mold assemblies 5 and a driving assembly 6. The sleeve frame 3 is horizontally slidably connected to the frame 1; the sleeve frame 3 is rotatably connected to the sleeve frame 3 through a rotating drum 13; the two mold assemblies 5 are arranged in parallel on the rotating frame 4, each mold assembly 5 includes a fixed mold and a movable mold, the fixed mold has a material injection hole, the fixed mold is fixedly connected to the rotating frame 4, and the movable mold is slidably connected to the rotating frame 4 so as to be able to close or open the mold relative to the fixed mold; the driving assembly 6 is used to drive the material injection holes of the two mold assemblies 5 to alternately connect with the material injection pipeline 2.

[0028] Specifically, the driving assembly 6 can be set to drive the rotating frame 4 to move linearly along a first direction relative to the frame 1, so that the material injection hole on the fixed mold of one of the mold assemblies 5 is separated from the docking material injection pipe 2, and then the rotating frame 4 can be driven to rotate relative to the frame 1, so that the two mold assemblies 5 are switched. After the switching, the rotating frame 4 moves linearly along a second direction opposite to the first direction relative to the frame 1, so that the material injection hole on the fixed mold of the other mold assembly 5 is plugged into the docking material injection pipe 2, so that the subsequent material injection pipe 2 can inject material into the main shot hole; the whole process does not require manual disassembly of the mold, the operation is relatively simple, and the production efficiency is further improved.

[0029] The driving assembly 6 includes a reciprocating screw unit 7, a rotating unit 8 and a locking member 9. The reciprocating screw unit 7 is used to drive the sleeve frame 3 to slide horizontally relative to the frame 1, the rotating unit 8 is used to drive the rotating frame 4 to rotate relative to the sleeve frame 3, and the locking member 9 is used to lock the rotating frame 4 so that the rotating frame 4 is only driven by the reciprocating screw unit 7.

[0030] The reciprocating screw 701 of the reciprocating screw unit 7 is rotatably connected to the frame 1, and its slider 702 is slidably connected to the guide rod 703, and the slider 702 is connected to the sleeve frame 3 through a straight rod 12; the driving assembly 6 also includes a driving unit 10, which is used to drive the reciprocating screw 701 of the reciprocating screw unit 7 to rotate; the frame 1 and the sleeve frame 3 are connected through a telescopic rod 11, and one end of the telescopic rod 11 is coaxially fixedly connected to the reciprocating screw 701 of the reciprocating screw unit 7. It should be noted that the driving unit 10 can be a rotary motor, and the output shaft of the rotary motor is coaxially fixedly connected to the reciprocating screw 701 of the reciprocating screw unit 7. Specifically, the output shaft of the rotating motor can drive the reciprocating screw 701 of the reciprocating screw unit 7 to rotate continuously, and the slider 702 can slide back and forth linearly along the reciprocating screw 701, and through the cooperation of the straight rod 12 and the telescopic rod 11, the sleeve frame 3 can be driven to slide back and forth linearly relative to the frame 1, that is, the rotating frame 4 can be driven to slide back and forth linearly relative to the frame 1, so that the material injection hole on the fixed mold in the mold assembly 5 can be separated or connected with the material injection pipe 2.

[0031] The rotating unit 8 includes a gear reduction box 801, a turntable 802, an incomplete inner gear ring 803, a first gear 804 and a second gear 805. The gear reduction box 801 is fixedly connected to the other end of the telescopic rod 11, the turntable 802 is coaxially fixedly connected to the output shaft of the gear reduction box 801, the incomplete inner gear ring 803 is fixedly connected to the turntable 802, the first gear 804 is rotatably connected in the sleeve frame 3, the second gear 805 is rotatably connected in the sleeve frame 3, and the first gear 804 is meshed with the second gear 805 to rotate the first gear 804; the incomplete inner gear ring 803 will mesh with the second gear 805 during the rotation process. Specifically, after the telescopic rod 11 coaxially fixedly connected to the reciprocating screw 701 transmits the rotational power to the gear reduction box 801, the gear reduction box 801 can drive the incomplete inner gear ring 803 to rotate relative to the sleeve frame 3 under the output deceleration. When the incomplete inner gear ring 803 is meshed with the second gear 805 during the rotation process, it will drive the first gear 804 meshed with the second gear 805 to rotate, and then drive the rotating drum 13 to rotate, that is, the rotating frame 4 fixedly connected to the rotating drum 13 rotates. It should be noted that, under the cooperation of the gear reduction box 801, the incomplete inner gear ring 803 rotates only one circle in a reciprocating linear motion of the rotating frame 4.

[0032] The locking member 9 includes a fixed rod 901, a locking rod 902, a locking hole 903 and a cam 904. The fixed rod 901 is fixedly installed in the sleeve frame 3, the locking rod 902 is elastically slidably connected to the fixed rod 901, the locking hole 903 is opened on the rotating drum 13, the cam 904 is coaxially and fixedly connected to the output shaft of the gear reducer 801, and the locking rod 902 is provided with a cross bar 905 that cooperates with the cam 904; in the process of the output shaft of the gear reducer 801 driving the cam 904 to rotate, the edge of the eccentric part of the cam 904 will continuously press the cross bar 905 to allow the locking rod 902 to be inserted into the locking hole 903. Specifically, when the incomplete inner gear ring 803 and the second gear 805 begin to disengage, the locking member 9 is converted from the unlocked state to the locked state, that is, the edge of the eccentric portion of the cam 904 coaxially fixedly connected to the output shaft of the gear reducer 801 begins to abut against the cross bar 905, so that the locking rod 902 fixedly connected to the cross bar 905 slides downward and is inserted into the locking hole 903 of the sleeve frame 3. In the subsequent process of docking or disengaging the material injection hole and the material injection pipe 2, the edge of the eccentric portion of the cam 904 will always abut against the cross bar 905, so that the locking rod 902 and the locking hole 903 are always in a locked state until the incomplete inner gear ring 803 and the second gear 805 begin to mesh. At the same time, the locking rod 902 is driven to reset by the provided compression spring, such as Fig. 9 As shown, a built-in groove is provided in a section of the push rod that is arranged horizontally, and one end of the compression spring is fixedly connected to the built-in groove. At the same time, an annular baffle is fixedly provided on the locking rod 902 and fixedly connected to the other end of the compression spring. In the process of the compression spring restoring its deformation, with the cooperation of the annular baffle, the locking rod 902 can be driven out of the locking hole 903, thereby completing the unlocking.

[0033] When it is necessary to switch the mold assembly 5, the material injection hole on the fixed mold of one of the mold assemblies 5 needs to be separated from the material injection pipe 2, so the separation stroke of the material injection hole and the material injection pipe 2 requires: the driving unit 10 drives the reciprocating screw 701 of the reciprocating screw unit 7 to rotate, so that the slider 702 slides along the first direction of the reciprocating screw 701, so that the rotating frame 4 slides linearly relative to the fixed frame, so that the material injection hole of the fixed mold of one of the mold assemblies 5 needs to be separated from the material injection pipe 2; and in the separation stroke, the cam 904 in the locking member 9 will continue to force the locking rod 902 to move downward, so that the locking rod 902 is always inserted into the locking hole 903 during the separation stroke, limiting the rotation of the rotating frame 4 relative to the frame 1, so that the rotating frame 4 can slide stably and horizontally relative to the frame 1, so that the material injection hole needs to be separated from the material injection pipe 2.

[0034] When the two mold assemblies 5 need to be switched, the rotating frame 4 needs to rotate relative to the frame 1, and the rotation stroke is: at this time, the driving unit 10 will drive the reciprocating screw 701 of the reciprocating screw unit 7 to continue to rotate, and the slider 702 will slide in the second direction opposite to the first direction. At the same time, under the transmission of the telescopic rod 11 and the gear reduction box 801, the rotating power drives the incomplete inner ring gear 803 connected to the sleeve frame 3 to rotate, so that the incomplete inner ring gear 803 will mesh with the second gear 805 for transmission, and with the cooperation of the first gear 804 meshing with the second gear 805, the rotating frame 4 can be driven to rotate relative to the frame 1 until the material injection hole of the fixed mold of the other mold assembly 5 is at the same level as the material injection pipe 2. plane, at this time the incomplete inner gear ring 803 will be disengaged from the second gear 805; and it should be noted that in this process, the locking member 9 is in an unlocked state, and when the material injection hole of the fixed mold of the other mold assembly 5 is in the same horizontal plane as the material injection pipe 2, the edge of the eccentric part of the cam 904 will begin to abut the cross bar 905, so that the locking rod 902 is inserted into the locking hole 903 on the rotating drum 13, thereby limiting the rotation of the rotating frame 4, and at the same time the reciprocating screw 701 continues to rotate, and with the cooperation of the slider 702 and the straight rod 12, the material injection hole of the fixed mold of the other mold assembly 5 can begin to dock and insert with the material injection pipe 2, thereby facilitating the subsequent material to pass from the material injection hole into the mold cavity formed between the fixed mold and the movable mold.

[0035] In summary, in all the processes above, there is no need to manually disassemble the mold, the operation is relatively simple, and the production efficiency is further improved.

[0036] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
