Description

Technical Field

[0001] The invention relates to the technical field of die-casting machines, in particular to a metal blank processing die-casting molding device which is convenient for demoulding. Background Art

[0002] The die-casting machine is mainly composed of a clamping mechanism, an injection mechanism, a hydraulic system, an electric control system and other parts. For some workpieces with multiple through holes on one side, such as flanges, the multiple through holes on one side of the workpiece match the raised core of the movable mold. When demolding, one side of this type of workpiece is easy to fall off from the fixed mold, but the other side is easy to stick to the core of the movable mold (assuming that one side of the multiple through holes of this type of workpiece is formed on the movable mold). For such workpieces, the existing technology usually relies on the ejector pin in the movable mold for demolding. The ejector-type demolding mechanism requires a through hole to accommodate the ejector pin to be opened in the cavity of the movable mold. During the injection stage, the ejector pin fills the entire through hole, and the ejector pin serves as part of the inner wall of the cavity; during the demolding stage, the ejector pin is ejected to separate the workpiece from the movable mold, and then a robot is used to grab the workpiece to the desired position.

[0003] The above scheme has certain problems: since the metal liquid injected through the through hole will flow to the vicinity of the through hole, the through hole part of the workpiece close to the ejector pin often does not meet the design requirements after cooling and needs to be polished and finished. In other words, the ejector-type demolding mechanism will affect the molding accuracy of this type of workpiece. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0033] It is worth noting that the present invention is suitable for Fig.13 The workpiece shown in FIG. 1 has a certain length in the direction of the connecting line between the movable mold 7 and the fixed mold 6 and has multiple through holes on one side, such as a flange.

[0034] According to the following Figure 1-Figure 13 The present invention describes a metal blank processing die-casting molding device with convenient demoulding provided by an embodiment of the present invention.

[0035] Combination Figure 1 and Figure 2 The embodiment of the present invention provides a metal blank processing die-casting molding device with convenient demolding, including a fixed mold 6 and a movable mold 7 that can form a mold assembly, a base 10 is provided below the mold assembly, the mold assembly is fixed to one end of the upper surface of the base 10, and a fixed seat 9 is installed at the other end of the upper surface of the base 10. A pressure cylinder 1 for pushing and pulling the movable mold 7 is provided on the fixed seat 9. When the pressure cylinder 1 is extended, the pressure cylinder 1 pushes the movable mold 7, so that the movable mold 7 gradually approaches and is pressed on the fixed mold 6. At this time, it is the mold closing state of the mold assembly. The cavity of the movable mold 7 and the fixed mold 6 forms a mold cavity for molding metal blanks. When the movable mold 7 gradually moves away from the fixed mold 6, the mold assembly is in the mold opening state, and the demolding operation can be performed at this time.

[0036] Preferably, a main column 8 is fixedly provided between the fixed mold 6 and the fixed seat 9, and when the pressure cylinder 1 is extended and retracted, the movable mold 7 can slide along the main column 8 to maintain the linear movement of the movable mold 7; further, the main column 8 is arranged in the area near the periphery of the movable mold 7 to avoid the main column 8 passing through the mold cavity.

[0037] Preferably, the nozzle 2 is arranged on a side of the fixed mold 6 away from the movable mold 7, and the liquid metal can be injected into the mold cavity through the nozzle 2 and formed in the mold cavity.

[0038] Combination Figure 1-Figure 4As shown, in order to facilitate demoulding, a clamping mechanism 5 is provided here, and the clamping mechanism 5 is located on both sides of the mold assembly. When the mold is opened, the clamping mechanisms 5 on both sides are close to the metal blank, so that the metal blank can be clamped, thereby locking the position of the metal blank, so that the metal blank can be separated from the movable mold 7.

[0039] like Figure 5 , Figure 7-Figure 9 As shown, in order to enable the clamping mechanism 5 to be close to the metal blank, a pressure assembly 3 is provided here, and the pressure assembly 3 can provide pressure to the clamping mechanism 5 in the direction of the metal blank. The pressure assembly 3 here is located on the side of the clamping mechanism 5 away from the mold assembly, and the pressure assembly 3 includes a guide rail 31, and the guide rail 31 includes a first inclined rail 312. After the metal blank is formed, the pressure cylinder 1 is shortened and provides a pulling force to the movable mold 7, so that the movable mold 7 can gradually move away from the fixed mold 6 and realize a gradual mold opening. In the process of the movable mold 7 moving away from the fixed mold 6, the pressure assembly 3 can be dragged to move, so that the pressure assembly 3 can gradually move in the moving direction of the movable mold 7, and then the first inclined rail 312 can rely on its own inclination to gradually push the clamping mechanism 5 close to the formed metal blank, so that the clamping mechanism 5 can clamp the formed metal blank in the mold opening state, and finally the metal blank is separated from the movable mold 7.

[0040] Therefore, the metal blank processing die-casting molding equipment with convenient demoulding provided by the embodiment of the present invention can realize the clamping mechanism 5 to clamp the metal blank during the mold opening process, and the metal blank can be locked on the clamping mechanism 5 after being clamped. At this time, when the movable mold 7 continues to perform the mold opening action, the metal blank will no longer move with the movable mold 7, and the demoulding operation can be realized. In this case, since the demoulding method provided by the present invention does not require the assembly of the ejector pin in the movable mold 7, the precision of the workpiece molding is guaranteed.

[0041] Reference Figure 10-12 As shown, the clamping mechanism 5 mentioned above includes a clamping plate assembly 51, a force-bearing rod 54 and a stroke increasing structure. The force-bearing rod 54 directly bears the pressure from the first inclined rail 312, so that the entire clamping mechanism 5 gradually approaches the metal blank.

[0042] Specifically, Fig.12 The clamping plate assembly 51 is located on the side of the pressure assembly 3 close to the mold assembly. The clamping plate assembly 51 includes a pressure seat 511 and a pressure plate body 512 arranged on the side of the pressure seat 511 close to the mold assembly. The force rod 54 is assembled on the clamping plate assembly 51. When the pressure assembly 3 moves with the movable mold 7, the first inclined rail 312 on the pressure assembly 3 can push the force rod 54 toward the direction of the metal blank, so that the clamping plate assembly 51 can move toward the direction of the metal blank together with the force rod 54.

[0043] Preferably, an elastic pad 513 is provided on the pressing plate body 512 to prevent the pressing plate body 512 from crushing the workpiece.

[0044] In actual use, some workpieces may have a shorter length in the direction of the line connecting the movable mold 7 and the fixed mold 6, for example, the workpiece is a flange head with a shorter axial length and a smaller diameter, or more precisely, a type of workpiece whose ratio of diameter divided by axial length is less than a certain threshold. It can be understood that the threshold is related to the inclination angle of the first ramp 312, or in other words, the displacement in the direction of "the movable mold 7 drags the pressure assembly 3 to move in the process of moving away from the fixed mold 6" is related to the ratio of the displacement in the direction of "the first ramp 312 pushes the clamping mechanism 5 to approach the formed metal blank", and the ratio of the two displacements is the tangent trigonometric function value of the inclination angle.

[0045] When die-casting this type of workpiece, the movable mold 7 will move to the right and drive the workpiece on the movable mold 7 to the right to the relative area away from the clamping mechanism 5, but the clamping mechanism 5 has not been pushed by the pressure assembly 3 to a state where it can clamp the workpiece. Therefore, a stroke increase structure is also provided here, which is used to expand the movement stroke of the pressure plate body 512 when the clamping plate assembly 51 approaches the metal blank, thereby avoiding the situation where the movable mold 7 carries the metal blank and has passed the clamping mechanism 5 but the clamping mechanism 5 has not yet reached the metal blank, and ensuring that when the metal blank reaches the area relative to the position of the clamping mechanism 5, the clamping mechanism 5 can reach the position of the metal blank and provide the corresponding clamping force to the metal blank. The stroke increasing structure is used to expand the moving stroke of the pressure plate body 512 when the clamping plate assembly 51 approaches the metal blank. That is, in essence, in the process of the entire clamping plate assembly 51 moving toward the metal blank, the stroke increasing structure can enable the pressure plate body 512 to move further, and the pressure plate body 512 and the pressure seat 511 can produce relative displacement in the moving direction of the clamping mechanism 5, so that the pressure plate body 512 can clamp the workpiece before the workpiece moves to the right to the relative area where it is separated from the clamping mechanism 5, to ensure that the workpiece can be separated from the movable mold 7.

[0046] Therefore, the metal blank processing die-casting molding equipment with convenient demoulding provided by the present invention can ensure that the clamping mechanism 5 has sufficient moving length to clamp the workpiece after the mold is opened, and ensure that the workpiece can be demoulded after being clamped.

[0047] Specifically, refer to Figure 10-12 As shown, the clamping plate assembly 51 mentioned above also includes a spring 514 and a guide rod 515. The spring 514 is used to connect the pressure plate body 512 and the pressure seat 511 (preferably, a blind groove for accommodating the spring 514 is provided on the pressure seat 511), so that the pressure seat 511 and the pressure plate body 512 can move relative to each other. Fig.10 The middle is the state where the spring 514 is fully compressed. Fig.12The middle is the natural state of the spring 514. Preferably, one end of the guide rod 515 is fixed on the pressure plate body 512, and the other end of the guide rod 515 passes through the pressure seat 511 and is fixed with a limiting shoulder 516 for limiting excessive extension of the spring 514.

[0048] Continue to refer to Figure 10-12 As shown, specifically, the stroke increasing structure mentioned above includes a pull rope 52 and a release assembly 53, wherein the release assembly 53 includes a roller 536, a bearing seat 537 is fixedly arranged on the side of the pressure seat 511 away from the pressure plate body 512, and the roller 536 is assembled on the bearing seat 537 through a bearing, one end of the pull rope 52 is fixed on the roller 536, and the other end of the pull rope 52 passes through the pressure seat 511 and is fixed on the pressure plate body 512. In this embodiment, when the roller 536 reels the pull rope 52, the pull rope 52 will generate a pulling force on the pressure plate body 512 and compress the spring 514 to form Fig.10 and Fig.11 In the state shown, on the contrary, when the pull rope 52 is unwound by the roller 536, the spring 514 is in a gradually extended state, thereby pushing the pressure seat 511 to move, that is, during the movement of the entire clamping mechanism 5, the movement stroke of the pressure plate body 512 can also be expanded by unwinding the pull rope 52.

[0049] It should be noted that, due to the setting of the limiting shoulder 516, the spring 514 will not be over-extended, so that the spring 514 is still in a compressed state when it is stretched to the maximum, thereby ensuring that the spring 514 can enable the pressure plate body 512 to generate the necessary pressure on the workpiece.

[0050] In addition, in order to ensure that the roller 536 can always keep the pull rope 52 tightened when demolding is not required, and that the roller 536 can unwind the pull rope 52 when demolding is required, a worm 534 and a worm wheel 532 are also provided. The worm wheel 532 is rotatably mounted on the bearing seat 537 through a bearing. A coaxial first gear 535 is installed at one end of the worm wheel 532, and a second gear 538 meshing with the first gear 535 is provided at one end of the roller 536. When the worm wheel 532 rotates, the first gear 535 on the worm wheel 532 can drive the second gear 538 to rotate, thereby realizing the rotation of the roller 536. In order to realize the rotation of the worm 534, a traveling gear 533 is provided to mesh with the worm 534. A wheel axle 531 is fixed in the middle of the traveling gear 533. The wheel axle 531 is installed on the force-bearing rod 54 through a bearing. The worm 534 is fixed on the wheel axle 531. The worm wheel 532 meshes with the worm 534. The pressure assembly also includes a rack 37 and a connecting column 34. The rack 37 is fixed on the guide rail 31 through the connecting column 34. The first inclined rail 312 is parallel to the rack 37. When the force-bearing rod 54 passes through the middle of the first inclined rail 312, the traveling gear 533 passes through the rack 37 to make the traveling gear 533 rotate.

[0051] In this embodiment, when the traveling gear 533 passes through the rack 37, the traveling gear 533 rotates, thereby driving the wheel axle 531 to rotate. When the wheel axle 531 rotates, the worm 534 can rotate, and then the worm wheel 532 can drive the second gear 538 to rotate through the first gear 535, so that the roller 536 can unwind the pull rope 52.

[0052] It should be noted that, due to the self-locking performance of the worm wheel 532 and the worm 534 , it can be ensured that when the wheel shaft 531 does not rotate, the roller 536 maintains the tightening state of the pull rope 52 .

[0053] like Fig.11 Preferably, a roller 55 is provided at one end of the force-bearing rod 54 close to the first inclined rail 312 to reduce the wear of the force-bearing rod 54 and the wear of the first inclined rail 312. In addition, a groove ring 551 is provided on the outer arc surface of the roller 55, and a limiting rail 32 adapted to the groove ring 551 is provided on the pressure assembly 3 to prevent the roller 55 from derailing and ensure the moving path of the roller 55.

[0054] Reference Figure 8 As shown, the guide rail 31 also includes a first flat rail 311 and a second flat rail 313. The first flat rail 311 is provided on one side of the first inclined rail 312. The first flat rail 311 is close to the side of the movable mold 7. The first flat rail 311 is used to keep the entire pressure assembly 3 from exerting pressure on the clamping mechanism 5 during the mold closing process. The second flat rail 313 is provided on the other side of the first inclined rail 312. The second flat rail 313 is provided because when the mold is opened, the first inclined rail 312 squeezes the clamping mechanism 5 and has put the pressure of the clamping mechanism 5 on the workpiece in place. At this time, the second flat rail 313 reaches a position opposite to the clamping mechanism 5. Although the entire pressure assembly 3 continues to move to the right (as shown in FIG. Fig.13 However, the second flat rail 313 will no longer exert pressure on the clamping mechanism 5, thereby enabling the clamping mechanism 5 to maintain a constant pressure on the workpiece.

[0055] Preferably, the first inclined rail 312 , the first flat rail 311 and the second flat rail 313 are an integrated structure, and all three are assembled on the assembly plate 33 . It is best to set the first inclined rail 312 , the first flat rail 311 and the second flat rail 313 and the assembly plate 33 as an integrated structure.

[0056] Combination Figure 4 , Figure 5 and Fig.13As shown, in order to enable the pressure assembly 3 to be dragged to move during the opening process of the movable mold 7, a force plate 36 integrated with the assembly plate 33 is provided on the side of the assembly plate 33 close to the movable mold 7, and a drag block 71 is provided on the side of the movable mold 7 close to the force plate 36, which is used to drag the force plate 36 to move during the gradual opening process, so that during the opening process of the movable mold 7, the drag block 71 gradually moves to the position of the force plate 36, thereby dragging the entire pressure assembly 3 to move by dragging the force plate 36.

[0057] When the movable mold 7 moves to the right to open the mold, the clamping mechanism 5 clamps the workpiece, and the movable mold 7 completely separates from the workpiece to the right, the demoulding operation is completed. In order to realize the reset of the clamping mechanism 5, the clamping mechanism 5 is restored from the clamping state to Figure 4 In the state shown, a push block 72 is also provided here, and an extended connecting plate 73 is installed on the side of the movable mold 7 away from the fixed mold 6. The push block 72 is installed on the extended connecting plate 73. During the mold closing process, the push block 72 pushes the force plate 36 to move the pressure assembly 3 to the left, so that the area corresponding to the clamping mechanism 5 returns to the area of ​​the first flat rail 311 and can wait for the next demolding operation.

[0058] like Figure 4 , Regarding the drag block 71 and the push block 72: in the mold assembly closed state, gaps are reserved between the drag block 71 and the clamping mechanism 5 and between the drag block 71 and the force plate 36, and at this time, the push block 72 is in close contact with the force plate 36. During the mold opening and demoulding process, the drag block 71 gradually approaches the force plate 36, and the push block 72 gradually moves away from the force plate 36 until the drag block 71 drags the force plate 36 to move. During this process, the distance between the push block 72 and the force plate 36 no longer changes; when the mold is re-closed, the movable mold 7 moves to the left, and at this time the push block 72 gradually approaches the force plate 36 to the left, and the drag block 71 gradually moves away from the force plate 36 to the left, until the push block 72 pushes the force plate 36 to the left. At this time, the entire pressure assembly 3 moves to the left with the movable mold 7, the movable mold 7 is gradually closed, and the area corresponding to the clamping mechanism 5 returns to the area of ​​the first flat rail 311 to achieve reset.

[0059] Preferably, a rubber pad is fixedly provided on one side of the drag block 71 close to the force-bearing plate 36 , and a rubber pad is also provided on one side of the push block 72 close to the force-bearing plate 36 .

[0060] Combination Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, in order to ensure the movement stability of the pressure assembly 3, a support component 4 is further provided here, and the support component 4 includes a side support wall 41, and the side support wall 41 is fixed to the base 10 through a support leg 413, and the side support wall 41 is located on the side of the pressure assembly 3 away from the clamping mechanism 5, and a guide structure for guiding the movement of the clamping mechanism 5 is provided on the side support wall 41, and this guide structure can limit the clamping mechanism 5 to gradually approach or move away from the metal blank along a straight line. Preferably, a concave rail 412 for guiding the movement of the assembly plate 33 is provided on the side support wall 41, and a convex rail adapted to the concave rail 412 is provided on the assembly plate 33.

[0061] Preferably, the above-mentioned guiding structure includes a guiding rod 415 and an assembly frame 414, one end of the guiding rod 415 is fixed on the side support wall 41, the assembly frame 414 is installed on the side support wall 41, the other end of the guiding rod 415 is fixed on the assembly frame 414, a side block 541 is provided on the force-bearing rod 54, the guiding rod 415 passes through the side block 541, and guides the entire clamping mechanism 5 by guiding the side block 541.

[0062] When in use, the pressure cylinder 1 gradually extends, so that the movable mold 7 gradually approaches the fixed mold 6. In this process, the push block 72 gradually pushes the force plate 36, so that the entire pressure assembly 3 moves until the mold is closed (refer to Figure 2 ), the position of the pressure assembly 3 at this time is as follows Figure 2As shown, the metal liquid is injected into the cavity in the movable mold 7 and the fixed mold 6 through the nozzle 2, and cooled and formed. After forming, the cylinder 1 is shortened, and the movable mold 7 gradually moves to the right, and the workpiece moves with the movable mold 7 inside the cavity of the movable mold 7. When the workpiece is completely separated from the cavity of the fixed mold 6, the drag block 71 can reach the position of the force plate 36, so that the drag block 71 can drag the entire pressure assembly 3 on the side support wall 41 to gradually move toward the pressure cylinder 1. As the pressure assembly 3 moves, the track relative to the position of the clamping mechanism 5 is transformed from the first flat track 311 to the first inclined track 312. As the pressure assembly 3 continues to move, the first inclined track 312 can push the force rod 54 to move. When the force rod 54 moves, the entire clamping mechanism 5 can move synchronously along the guide rod 415. At the same time, the travel gear 5 33 rotates through the rack 37, thereby driving the wheel shaft 531 to rotate. When the wheel shaft 531 rotates, the worm 534 can rotate, and then the worm wheel 532 can drive the second gear 538 to rotate through the first gear 535, so that the roller 536 can unwind the pull rope 52. When the pull rope 52 is unwinding, the displacement of the pressure plate body 512 relative to the pressure seat 511 is larger, thereby ensuring that the pressure plate body 512 clamps the workpiece. After the pressure plate body 512 clamps the workpiece, the workpiece will no longer move with the movable mold 7, thereby realizing the mutual separation of the workpiece and the movable mold 7. In the process of mutual separation of the workpiece and the movable mold 7, the track opposite to the force rod 54 is transformed from the first inclined rail 312 to the second flat rail 313; after the demoulding is completed, the workpiece is taken out from the top of the equipment using a manipulator.

[0063] The next cycle of die casting can then be carried out.
