At the same time, China's aluminum alloy casting technology and production level are also constantly improving. Aluminum alloy round ingots are a common intermediate product in the casting industry and are widely used in aviation, automobiles, ships, machinery and other fields.

[0004] For example, the publication number is: CN219881234U, and the name is: "A kind of aluminum alloy casting mold", which includes a casting lower mold, a casting upper mold and a ventilation reserved groove, and also includes a heat sink, a first cover plate and a second cover plate. The casting upper mold is located on the top of the casting lower mold, and a ventilation reserved groove is opened horizontally through the bottom of the casting lower mold. Cover openings are respectively provided at both ends of the ventilation reserved groove. A heat sink is installed on the bottom of the ventilation reserved groove by bolts, and the cover openings at both ends of the ventilation reserved groove are respectively covered with a first cover plate and a second cover plate, and an exhaust fan is installed in the first cover plate by bolts.

[0045] 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.

[0046] See also Figure 1-9 An embodiment of the present invention provides an aluminum alloy casting heat treatment production line, comprising: a frame 1; a turntable 2, which is rotatably connected to the frame 1; and a material discharge chute 22 is provided on the turntable 2.

[0047] A plurality of casting modules 3 are distributed in a circular array on the turntable 2; specifically, there are four casting modules 3 vertically; each casting module 3 includes two molds 36, both molds 36 are slidably connected to the turntable 2, and the two molds 36 abut against each other.

[0048] Specifically, the casting mold group 3 includes two upright frames 31 fixedly connected to the turntable 2. Specifically, the upright frames 31 are arranged at an angle; a lifting rod 32 is vertically slidably connected to the turntable 2, and abutment rods 34 are slidably abutted between the lifting rod 32 and the two upright frames 31. The two abutment rods 34 are respectively fixedly connected to the two molds 36 in a one-to-one correspondence.

[0049] Specifically, a sliding groove 311 is provided on each of the two upright frames 31, and two abutting grooves 321 are provided on the lifting rod 32; more specifically, a certain angle is provided between the abutting groove 321 and its corresponding sliding groove 311; the two abutting rods 34 are respectively and one-to-one correspondingly slidably abutted against the two abutting grooves 321, and the two abutting rods 34 are fixedly connected with a slider 35, and the two sliders 35 are respectively and one-to-one correspondingly slidably connected in the two sliding grooves 311.

[0050] Specifically, the lifting rod 32 slides in the following manner: the lifting rod 32 is fixedly connected with two vertical rods 33 , and both vertical rods 33 are slidably connected to the turntable 2 ; more specifically, the turntable 2 is provided with sliding holes for the two vertical rods 33 to slide vertically.

[0051] Specifically, the specific method of driving the lifting rod 32 to achieve lifting on the turntable 2 is: a reciprocating screw rod 37 is rotatably connected to the turntable 2, the reciprocating screw rod 37 is screwed to the lifting rod 32, a first gear 38 is fixedly connected to the reciprocating screw rod 37, and two first racks 39 are fixedly connected to the frame 1, and the two first racks 39 are both engaged with the first gear 38.

[0052] During use, when the first gear 38 engages with the first rack 39, it drives the reciprocating screw 37 to rotate, thereby causing the lifting rod 32 threadedly connected to the reciprocating screw 37 to move vertically downward. During the descent process, the lifting rod 32 drives the two molds 36 to descend synchronously through the cooperation between the abutment groove 321 and the abutment rod 34, and the cooperation between the slide groove 311 and the slider 35. In the process of descent, the two molds 36 move away from each other, so that the molded parts located between the two molds 36 can fall from the discharge chute 22 and the molded parts can be collected uniformly.

[0053] In an embodiment of the present invention, two first racks 39 are provided, wherein the stroke of one first rack 39 meshing with the first gear 38 drives the reciprocating screw 37 to rotate, causing the lifting rod 32 to descend, thereby causing the two molds 36 to move away from each other during the downward movement, and perform the demolding stroke; and the stroke of the other first rack 39 meshing with the first gear 38 drives the reciprocating screw 37 to rotate again, and this rotation will cause the lifting rod 32 to rise and reset, and cause the two molds 36 to approach and abut each other during the upward movement, thereby completing the mold closing stroke.

[0054] The casting bucket 4 is rotatably connected to the turntable 2 , and the casting bucket 4 is in abutment with each mold 36 .

[0055] It should be noted that: after the casting bucket 4 rotates, when the mouth of the casting bucket 4 faces downward (that is, when the casting bucket 4 is located at the pouring station), the casting bucket 4 pours the material into the casting molding cavity formed between the two molds 36, and the two molds 36 are in a state of mutual abutment. At this time, the outer side of the casting bucket 4 and the two molds 36 are also in a state of abutment. That is to say, at this time, when the casting bucket 4 rotates around the axis of the turntable 2, the abutment will drive the two molds 36 to rotate synchronously, that is, the turntable 2 rotates synchronously.

[0056] Specifically, the casting ladle 4 is connected to the turntable 2 in the following manner: a circular groove 21 is provided on the turntable 2 , a support rod 41 is slidably connected in the circular groove 21 , and the casting ladle 4 is rotatably connected to the support rod 41 .

[0057] The driving mechanism 5 includes a rotating column 51 rotatably connected to the turntable 2; specifically, the driving mechanism 5 includes a driven column 52 fixedly connected to the turntable 2, the rotating column 51 is rotatably connected to the driven column 52, a through slot 511 is provided on the rotating column 51, and a plurality of lifting slots 521 are provided on the driven column 52, each lifting slot 521 is connected to a connecting slot 522, and a plurality of limit plates 523 are fixedly connected in the connecting slot 522, a second gear 53 is fixedly connected to the casting bucket 4, a second rack 54 is vertically slidably connected to the support rod 41, and a cross bar 55 is fixedly connected to the second rack 54, the cross bar 55 passes through the through slot 511, and an abutment block 56 is elastically connected to the end of the cross bar 55; specifically, a second spring 57 is provided between the abutment block 56 and the cross bar 55; the abutment block 56 is in sliding abutment with the connecting slot 522, each lifting slot 521, and each limit plate 523.

[0058] In another embodiment, if Figure 10 As shown, the casting bucket 4 is fixedly connected to an abutment frame 58, and the cross bar 55 is fixedly connected to a slide bar 59, which slides and abuts against the abutment frame 58; the slide bar 59 slides and abuts against the abutment frame 58, thereby driving the casting bucket 4 to rotate.

[0059] It should be noted that the thickness of the limiting plate 523 gradually increases from one end to the other end, and the abutment block 56 abuts against the relatively thick end. When the abutment block 56 rotates with the axis of the turntable 2, it can drive the driven column 52 to move synchronously; and when the abutment block 56 abuts against the thinner end of the limiting plate 523, since the abutment block 56 is elastically set on the cross bar 55, the abutment block 56 can pass through the limiting plate 523 smoothly, and will not drive the driven column 52 to move synchronously due to the abutment between the abutment block 56 and the limiting plate 523; that is: through the limitation of the limiting plate 523, the abutment block 56 can only rotate in one direction in the connecting groove 522.

[0060] Specifically, one end of the abutting block 56 has an inclined surface 561 , and the inclined surface 561 abuts and cooperates with each limiting plate 523 .

[0061] In the embodiment of the present invention, there is a driving source (not shown in the figure) for driving the rotating column 51 to rotate forward and reverse.

[0062] When in use, the rotating column 51 first rotates in the first direction, and the through slot 511 abuts against the cross bar 55, so that the abutment block 56 moves vertically upward in one of the lifting slots 521. It should be noted that, if Figure 8In the state shown, at this time, the abutment block 56 abuts against a plane away from the inclined surface 561 and the thicker end of the limit plate 523. As the rotating column 51 rotates along the first direction, the abutment force between the abutment block 56 and the limit plate 523 will become larger and larger, so the abutment block 56 will be driven to passively move vertically upward in the lifting groove 521. The abutment block 56 drives the cross bar 55 and the second rack 54 to move upward synchronously. Through the meshing action of the second rack 54 and the second gear 53, the casting bucket 4 is driven to rotate on the support rod 41, so that the mouth of the casting bucket 4 faces downward, so that the casting bucket 4 is located at the pouring station. As the casting bucket 4 rotates, the molten aluminum alloy raw material in the casting bucket 4 is poured into the molding cavity between the two molds 36.

[0063] Then, the rotating column 51 continues to rotate in the first direction. Since the abutment block 56 is located at the top of the lifting groove 521 at this time, the rotation of the rotating column 51 will drive the driven column 52 and the turntable 2 to rotate synchronously through the abutment effect of the abutment block 56 and the lifting groove 521, that is, each casting module 3 is synchronously rotated ninety degrees in the first direction. During the rotation process, the casting bucket 4 at the pouring station completes the pouring of the aluminum alloy raw material.

[0064] After the pouring is completed, the rotating column 51 rotates in the second direction. At this time, the abutment block 56 is driven to move vertically downward in the lifting groove 521 through the abutment cooperation between the through groove 511 and the cross bar 55, until the abutment block 56 is separated from the lifting groove 521 and reaches the connecting groove 522; in the process of the abutment block 56 moving downward, the cross bar 55 and the second rack 54 are driven to move downward synchronously, and the casting bucket 4 is driven to rotate and reset through the meshing action of the second rack 54 and the second gear 53.

[0065] Then, the rotating column 51 continues to rotate in the second direction. Since the abutment block 56 is located in the connecting groove 522 at this time, the rotating column 51 will drive the cross bar 55 to rotate synchronously, thereby moving the abutment block 56 in the connecting groove 522. During the movement, the abutment block 56 will slide and abut against the limit plate 523, so that the abutment block 56 will shrink in the direction of the cross bar 55, so that the abutment block 56 can smoothly pass through the limit plate 523 and move from one end of the limit plate 523 to the other end. It can be understood that in this process, since the abutment block 56 does not effectively abut against the driven column 52, the driven column 52 remains stationary. On the other hand, since the second rack 54 and the support rod 41 are in a sliding connection relationship, during the rotation of the rotating column 51, it will drive the cross bar 55, the second rack 54, the support rod 41, and the casting bucket 4 to rotate synchronously, that is, the support rod 41 slides in the circular groove 21, so that the casting bucket 4 is rotated to another casting mold group 3 position, ready for the next casting operation.

[0066] The rotation stroke of the rotating column 51 along the first direction includes a casting stroke and a synchronous rotation stroke;

[0067] During the pouring process: the casting ladle 4 is driven to rotate to the pouring station, so that the aluminum alloy raw material in the casting ladle 4 is poured into the space between the two molds 36 in the abutting state in one of the casting mold sets 3;

[0068] Synchronous rotation stroke: the casting ladle 4 remains at the unloading station and rotates synchronously with the turntable 2 following the rotating column 51 in the first direction;

[0069] During the rotation of the turntable 2, there is a demoulding stroke for driving the two molds 36 away from each other, and a mold closing stroke for driving the two molds 36 toward each other and abutting each other.

[0070] The rotation stroke of the rotating column 51 in the second direction includes a reset stroke and a switching stroke;

[0071] In the reset stroke: driving the casting ladle 4 to rotate in the reverse direction to reset;

[0072] During the switching stroke, the turntable 2 remains stationary, while the casting ladle 4 rotates in the second direction around the axis of the rotating column 51 , so that the casting ladle 4 moves to another casting mold assembly 3 position.

[0073] Preferably, an anti-adhesion mechanism 6 is also included, which includes two push rods 61, and the two push rods 61 are respectively slidably connected to the two molds 36, and a first spring 62 is provided between each push rod 61 and its corresponding mold 36. Two fixed plates 63 are fixedly connected to the turntable 2, and the two fixed plates 63 are respectively slidably abutted against the two push rods 61.

[0074] In the process of the two molds 36 moving downward and away from each other to achieve demolding, in order to avoid the possibility that the molded part may adhere to any mold 36, which may cause the molded part to fail to be truly demolded, during the descent of the two molds 36, the push rod 61 will slide and abut against its corresponding fixed plate 63. Under the action of the abutment between the two, one end of the push rod 61 will slide on the mold 36. Through the relative movement of the mold 36 and the push rod 61, the molded part that may adhere to the mold 36 will be pushed down, so that the molded part can be demolded smoothly.

[0075] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
