Description

Technical Field

[0001] The invention relates to the field of aluminum die casting of automobile parts, in particular to a material handle cutting device of an aluminum die casting mold for automobiles. Background Art

[0002] Many parts in cars need to be formed by aluminum die casting, such as engine cylinder head, water pump housing, crankshaft housing, brake caliper and other parts. Aluminum die casting is to pour molten aluminum into the pouring port of the die casting mold, and use the hydraulic press to move the movable mold of the die casting mold to squeeze the aluminum liquid, so that the aluminum liquid cools and solidifies in the die casting mold cavity.

[0003] Generally, a residual material trough is designed in the aluminum die-casting mold, that is, the mass of aluminum liquid poured each time is slightly greater than the mass required for the molded object, in order to ensure the effective molding of the die-cast object. This type of die-casting method will allow excess aluminum liquid to enter the residual material trough. After die-casting, the molded part in the residual material trough will serve as the residual material handle. There are one or more material handles. After the aluminum die-casting mold is opened, the molded object is grabbed onto the conveyor line by a manipulator, and air-cooled by the fan on the conveyor line body. Wait for the temperature of the molded object to drop before manually knocking the handle to remove it. The knocking and removal of the handle must wait until the temperature of the molded object drops to a certain value. If the temperature of the molded object itself is too high, the inside of the molded object is still relatively soft at this time, and it may not be directly broken and removed by knocking, or the breakage of the handle will extend to the main part of the mold.

[0031] It also includes: a local cooling unit, which is used to locally cool the connection between the forming groove 3 and the residual material groove 4, and the local cooling unit is arranged inside the movable mold 2;

[0032] The product loosening unit is used to loosen the residual material groove 4 and the forming groove 3. The product loosening unit is arranged on the side of the movable mold 2 away from the fixed mold 1. The outer side of the product loosening unit is also provided with a touch component for knocking the residual material groove 4.

[0033] The stabilizing unit is used to stabilize the molded product inside the molding groove 3 , and the stabilizing unit is arranged between the movable mold 2 and the baffle 6 .

[0034] The local cooling unit includes a cooling assembly mold 12 fixedly mounted at the connection between each residual material groove 4 and the forming groove 3, and the cooling assembly mold 12 is hollow. A cooling channel 11 from top to bottom is opened inside the movable mold 2, and the cooling channel 11 passes through the connection between each residual material groove 4 and the forming groove 3. Several cooling assembly molds 12 are fixedly connected with the cooling channel 11. Each cooling assembly mold 12 is provided with a V-shaped flow channel 13 on one end face close to the fixed mold 1. The upper port of the cooling channel 11 is fixedly connected to an upper through pipe 15, and the lower port of the cooling channel 11 is fixedly connected to a lower through pipe 14. A sealing cylinder 19 is provided on one end face of the movable mold 2 away from the fixed mold 1, and the position of the sealing cylinder 19 relative to the movable mold 2 is fixed. A piston disk 20 is slidably installed inside the sealing cylinder 19, and the piston disk 20 A push rod 22 is fixedly arranged inside and passes through the sealing cylinder 19. A first tension spring 21 is fixedly installed between the side of the piston disc 20 away from the fixed mold 1 and the sealing cylinder 19. The end of the upper through pipe 15 away from the cooling channel 11 is connected to the outer wall of the sealing cylinder 19, and the outer wall of the sealing cylinder 19 is also equipped with a connecting pipe 16. The assembly points of the upper through pipe 15, the connecting pipe 16 and the sealing cylinder 19 are all located on the side of the sealing cylinder 19 close to the fixed mold 1, and the outer walls of the upper through pipe 15 and the connecting pipe 16 are respectively equipped with two one-way valves, among which the one-way valve installed on the upper through pipe 15 can unilaterally allow the cooling medium inside the sealing cylinder 19 to be transported to the inside of the cooling channel 11 through the upper through pipe 15, while the one-way valve installed on the connecting pipe 16 unilaterally allows the sealing cylinder 19 to absorb the cooling medium.

[0035] The cooling channel 11 is serpentine from top to bottom, and each bending angle is greater than ninety degrees, which can prevent the cooling medium from easily remaining in the cooling channel 11. Through the vertical placement and the heating of the movable mold 2, the residual medium can be directly discharged through the lower pipe 14.

[0036] The product loosening unit includes a limit frame 17 fixedly arranged at one end of the movable mold 2 away from the fixed mold 1, and a cover plate 18 is fixedly arranged on the other end surface of the limit frame 17, a connecting sleeve is fixedly assembled between the cover plate 18 and the sealing cylinder 19, and a push rod 22 is slidably embedded in the interior of the connecting sleeve, and a second push plate 41 and a first push plate 24 are slidably assembled in the interior of the limit frame 17, at least one first push rod 25 is slidably penetrated in the interior of the molding groove 3, and at least one second push rod 27 is slidably penetrated in the interior of each residual material groove 4 The first push rod 25 and the second push rod 27 are fixedly mounted on the end faces away from the fixed mold 1 inside the first push plate 24 and the second push plate 41 respectively, and the outer surfaces of the second push rod 27 and the first push rod 25 are respectively covered with the second spring 28 and the first spring 26, and the first spring 26 and the second spring 28 are respectively placed between the movable mold 2 and the first push plate 24, and between the movable mold 2 and the second push plate 41. When the push rod 22 is pushed, it can not only transport the cooling medium, but also push the first push plate 24 and the second push plate 41.

[0037] The distance between the first push plate 24 and the movable mold 2 is smaller than the distance between the second push plate 41 and the movable mold 2 , which ensures that the push rod 22 pushes the second push plate 41 first, and then pushes the first push plate 24 through the protrusion 23 .

[0038] The side wall of the second push plate 41 is also fixedly provided with a protrusion 23 for pushing the second push plate 41 . The function of the protrusion 23 is to ensure that the second push plate 41 can effectively touch the first push plate 24 during the movement.

[0039] The stabilization unit includes a rotating shaft 8 rotatably assembled on the side wall of the movable mold 2, and the outer surface of the rotating shaft 8 is fixedly provided with a tooth column 9 and a brake plate 10 which plays a pressing limit role on the molded product. An end face of the baffle 6 close to the fixed mold 1 is fixedly provided with an elastically retractable elastic tooth plate 7, and the elastically retractable tooth plate 7 is movably engaged with the tooth column 9. When the movable mold 2 is separated from the fixed mold 1, after the movable mold 2 is separated from the fixed mold 1 by a certain distance, the continuous movement of the movable mold 2 can make the elastically retractable tooth plate 7 engage with the tooth column 9, so that the brake plate 10 rotates, and presses the molded product inside the molding groove 3.

[0040] How this solution works:

[0041] After the aluminum metal part is die-casted in the state where the fixed mold 1 and the movable mold 2 are in the mold-clamping state, when the movable mold 2 is separated from the fixed mold 1 by the push rod 5, the distance between the movable mold 2 and the fixed mold 1 gradually increases, and the push rod 22 will also touch the baffle 6, and the push rod 22 is pushed into the inside of the sealing cylinder 19 under the action of the baffle 6. At this time, the first tension spring 21 is extended, and the cooling medium in the sealing cylinder 19 is transported to the inside of the cooling channel 11 through the upper through pipe 15 under the action of the piston disc 20. The cooling medium enters the inside of the cooling assembly mold 12 through the cooling channel 11, thereby cooling the residual material connection part formed on the V-shaped flow channel 13 After the cooling treatment, this part is harder than other parts, and the subsequent push rod 22 continues to move into the sealing cylinder 19, and will touch the second push plate 41 and the first push plate 24 in sequence. The second push plate 41 pushes the material handle in the residual material groove 4 through the second push rod 27. During the separation of the movable mold 2 and the fixed mold 1, the brake plate 10 is also caused to rotate through the elastic telescopic tooth plate 7 to press and limit the molded product in the molding groove 3, that is, the molded product is not touched, and the material handle is pushed alone. At this time, since the connection between the material handle and the molded product is cooled and hardened, the material handle can be broken to separate the material handle from the molded product.

[0042] By directly subjecting the connection between the material handle and the molded product to local cooling treatment and then mechanically dividing the material handle, it is possible to avoid the situation where the molded product body is torn when the material handle is manually struck and divided due to the temperature of the connection being not low enough.

[0043] After the handle is partially detached, the push rod 22 continues to go deeper, and the molded product in the molding groove 3 can be loosened. When the movable mold 2 is subsequently reset to allow the brake plate 10 to rotate, and there is still a certain distance between the movable mold 2 and the fixed mold 1, the loose molded product can be directly removed by the existing robot.

[0044] Example 2: Please refer to Figure 7 and Figure 8 This embodiment is a further explanation of the embodiment 1. The touch component includes at least one limiting sleeve 32 fixedly arranged on an end surface of the cover plate 18 away from the fixed mold 1, and a touch rod 31 is slidably installed inside the limiting sleeve 32. One end of the touch rod 31 extending out of the limiting sleeve 32 is fixedly equipped with a frame plate 30. An optical axis 29 is fixedly arranged on an end surface of the movable mold 2 away from the fixed mold 1, and the optical axis 29 slides through the frame plate 30. A second tension spring 33 is fixedly arranged on the outer surface of the frame plate 30 and the movable mold 2 corresponding to the optical axis 29. A driving component is arranged between the frame plate 30 and the movable mold 2. The second tension spring 33 applies an elastic pulling force toward the fixed mold 1 to the touch rod 31 through the frame plate 30.

[0045] The driving assembly includes a sleeve frame 34 fixedly arranged on an end face of the movable mold 2 away from the fixed mold 1, and a positioning shaft 36 is rotatably installed inside the sleeve frame 34, a gear 38 is fixedly mounted on the outer surface of the positioning shaft 36, and a driving tooth plate 35 movably engaged with the gear 38 is slidably installed inside the sleeve frame 34, a third spring 40 is arranged between the end of the driving tooth plate 35 close to the fixed mold 1 and the movable mold 2, a movable toothless ratchet 37 is also fixedly arranged on the outer surface of the positioning shaft 36, and a lifting tooth plate 39 movably engaged with the movable toothless ratchet 37 is fixedly arranged on the end of the frame 30 close to the sleeve frame 34, when the driving tooth plate 35 moves toward the fixed mold 1, the lifting tooth plate 39 is moved in the direction away from the fixed mold 1 under the meshing transmission of the movable toothless ratchet 37 on the lifting tooth plate 39.

[0046] The outer diameter of the movable toothless ratchet 37 is larger than that of the gear 38 , and the distance between the push rod 22 and the baffle 6 is larger than the distance between the second tension spring 33 and the baffle 6 , that is, during the separation process of the movable mold 2 and the fixed mold 1 , the push rod 22 contacts the baffle 6 first.

[0047] In this embodiment: considering that directly pushing the material handle slowly will cause deformation and bending between the cooled connection part and the material handle, that is, pushing will not separate the material handle from the molded product, in this solution, before the baffle 6 pushes the push rod 22 and touches the second push plate 41, the baffle 6 can first push the driving tooth plate 35 to trigger the active toothless ratchet 37 to rotate counterclockwise for one circle. During the rotation, the ratchet teeth of the active toothless ratchet 37 will move the lifting tooth plate 39 in the direction away from the fixed mold 1. After moving a certain distance, due to the limited number of ratchet teeth of the active toothless ratchet 37, the lifting tooth plate 39 will no longer be restricted, and the lifting tooth plate 39 will be lifted. The second tension spring 33 quickly resets under the action of the touch rod 31, so that the touch rod 31 quickly hits the second push plate 41 once. It should be noted that the elastic stiffness of the third spring 40 is greater than the elastic stiffness of the plurality of second springs 28. When the touch rod 31 quickly resets and hits the second push plate 41, it can overcome the elastic pressure of the second spring 28, allowing the second push rod 27 to transmit the hitting force, thereby quickly hitting the material handle part inside the residual material trough 4 once. Through the instantaneous hitting, the cooled and hardened connecting part is quickly broken, so as to assist the subsequent second push rod 27 in pushing the material handle part, thereby further ensuring that the segmentation of the material handle will not cause damage to the main body of the formed product.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
