The term "and / or" as used in this description includes any and all combinations of one or more of the associated listed items.
[0024] The following combination Figures 1-8 The invention provides an injection mold for copper castings capable of rapid demoulding.
[0025] like Figure 1 and Figure 2 As shown, in one embodiment, a quick-demolding copper casting processing injection mold includes a lower mold 1, an upper mold 2, a casting clamping part 3, a material placement platform 4 and a material moving part 5.
[0026] The lower mold 1 has a lower abutment 11 and a cavity 12 .
[0027] The upper mold 2 includes an upper abutment 21 and a core 22, which are used to cooperate with the cavity 12 to complete the molding of the copper casting.
[0028] It should be noted that the injection mold for copper castings with rapid demolding is mounted on a casting platform. The casting platform includes an upper platen, a mounting frame, and a drive source. The drive source is fixedly mounted on the top of the mounting frame. The upper platen has a through hole and is mounted on the mounting frame so that it can be displaced in the height direction. The output end of the drive source is connected to the upper platen. The core 22 is connected to the upper platen by bolts. The upper abutment 21 is mounted on the upper platen so that it can be displaced in the height direction. The lower mold 1 is fixed to the inner bottom wall of the mounting frame by bolts.
[0029] The casting clamp 3 comprises an upper clamping jaw 31 and a lower clamping plate 32 , which is detachably mounted on the lower abutment 11 and is used to clamp the copper casting after demoulding.
[0030] It should be noted that the upper clamp 31 includes a top inclined plate, a transverse connecting plate and a lower support rod. The bottom of the top inclined plate is fixedly connected to the transverse connecting plate, and the lower support plate is fixedly connected to the bottom of the transverse connecting plate. The height of the bottom end of the top inclined plate is lower than the height of the bottom of the transverse connecting plate.
[0031] The unloading platform 4 is located on one side of the lower mold 1 and is used to place the copper casting after demoulding.
[0032] The material moving member 5 is provided on a set of side walls of the lower mold 1 and is used to drive the casting clamping member 3 to move toward the material unloading platform 4.
[0033] The lower abutment 11 is installed on the lower mold 1 so as to be movable upward in the height direction. The lower abutment 11 includes a lower abutment block 11 - 1 and a traction frame 11 - 2 . The traction frame 11 - 2 and the material moving member 5 are located on the same side.
[0034] The upper abutment 21 is mounted on the upper mold 2 so as to be displaceable in the height direction.
[0035] Specifically, when casting copper castings, the casting liquid is injected into the mold cavity 12, and the core 22 drives the upper support member 21 to move downward into the mold cavity 12. The core 22, the lower support member 11, the mold cavity 12 and the upper support member 21 enclose a complete casting space to shape the casting liquid.
[0036] When demolding the formed copper casting, the core 22 moves upward, the core 22 is separated from the lower mold 1, and the upper clamp 31 begins to move between the core 22 and the lower mold 1. During this process, the copper casting is still located in the mold cavity 12, so the core 22 is separated from the top of the copper casting, and at the same time, the bottom of the upper abutment 21 is still in contact with the top of the copper casting.
[0037] As the core 22 continues to move upward, the core 22 begins to drive the upper push piece 21 to move upward synchronously. Since the upper clamp 31 is located on the upward path of the copper casting at this time, the upward path of the copper casting is blocked by the upper clamp 31, and the copper casting remains in the mold cavity 12, thereby separating the bottom of the upper push piece 21 from the top of the copper casting.
[0038] The core 22 and the upper push piece 21 continue to move upward, and begin to pull the lower push piece 11 upward synchronously through the traction frame 11-2. Since the casting clamping claw is installed on the lower push piece 11, the upper clamping claw 31 and the lower push block 11-1 clamp the copper casting together and move it upward, thereby removing the copper casting from the cavity 12.
[0039] During the process of removing the copper casting from the cavity 12, when the distance between the bottom of the copper casting and the top of the lower mold 1 is equal to the thickness of the lower clamping plate 32 along the height direction, the lower clamping plate 32 begins to move below the copper casting while following the upward movement of the traction frame 11-2.
[0040] Then the upper mold 2 begins to move downward, and the core 22 drives the lower block 11-1 to move downward through the traction frame 11-2. Since the lower clamp 32 is located on the downward path of the copper casting, when the lower clamp 32 moves down to its bottom and abuts the top of the lower mold 1, the lower clamp 32 begins to separate from the lower block 11. At the same time, the lower clamp 32 begins to be stuck on the material moving piece 5. The copper casting is clamped by the lower clamp 32 together with the upper clamp 31 and retained above the lower mold 1. The lower block 11 continues to move downward. Since the downward path of the copper casting is blocked by the lower clamp 32, the lower block 11-1 begins to separate from the bottom of the copper casting.
[0041] After the lower abutment 11 is separated from the copper casting, the material moving member 5 is moved, and the material moving member 5 drives the demoulded copper casting to move to the unloading platform 4 through the lower clamping plate 32, thereby completing the automatic unloading and taking process of the copper casting.
[0042] like Figure 3 As shown, in one embodiment, the upper abutment 21 includes an upper abutment block 21-1, a connecting locking member 21-2 (see Figure 2 ) and a traction rod 21-3, the core 22 has a lifting hole 22-1 set through in the height direction (see Figure 2 ), the upper block 21-1 passes through and is slidably installed in the lifting hole 22-1, and the top end of the upper block 21-1 extends out of the lifting hole 22-1 and is fixedly connected to the traction rod 21-3.
[0043] It should be noted that the inner wall of the lifting hole 22-1 has a snap-fit groove, and the upper stop 21-1 has a retraction cavity along its width, within which the connecting locking member 21-2 is mounted. When the bottom of the upper stop 21-1 is flush with the bottom of the core 22, one end of the connecting locking member 21-2 extends out of the retraction cavity and is inserted into the snap-fit groove. When the core 22 and the upper stop 21-1 are relatively movable, the connecting locking member 21-2 is entirely located within the retraction cavity.
[0044] The connecting locking member 21-2 includes a telescopic spring and a clamping block. The clamping block is installed in the retraction chamber so as to be displaceable in the horizontal direction. One end of the telescopic spring abuts against the inner wall of the retraction chamber, and the other end abuts against the side wall of the clamping block away from the opening of the retraction chamber.
[0045] Specifically, in the process of separating the core 22 from the top of the copper casting, when the core 22 begins to move upward, the clamping block is squeezed by the inclined surface at the bottom end of the clamping groove, and the clamping block retracts into the retraction cavity by squeezing the telescopic spring. In the subsequent process of the core 22 continuing to move upward relative to the upper block 21-1, the clamping block housed in the retraction cavity is pushed by the elastic force of the telescopic spring to abut against the inner wall of the lifting hole 22-1.
[0046] In order to enable the core 22 to move up or down relative to the upper block 21 - 1 , the end of the traction rod 21 - 3 away from the upper block 21 - 1 has a locking block, and the shape of the locking block is an isosceles trapezoid.
[0047] The surface of the core 22 adjacent to the traction rod 21-3 has a driving block, and the top and bottom ends of the driving block both have inclined driving surfaces. The distance between the end of the locking block away from the traction rod 21-3 and the core 22 is greater than the distance between the end of the driving block away from the traction rod 21-3 and the core 22.
[0048] An unlocking guide frame is provided on the side wall of the lower mold 1 adjacent to the traction rod 21-3, and a support slide bar and a limit plate are fixedly connected to the unlocking guide frame. The support slide bar is installed between the limit plate and the unlocking guide frame, and a limit block is slidably installed on the support slide bar. A retraction spring is installed between the limit blocks, and the limit blocks are located on the lifting and lowering displacement path of the driving block and the locking block.
[0049] The surface of the limiting block adjacent to the lower mold 1 has a limiting groove, and the shape of the limiting groove matches the shape of the locking block.
[0050] Specifically, when the core 22, the lower push piece 11, the cavity 12 and the upper push piece 21 enclose a complete casting space, the locking block is inserted into the limiting slot, and the driving block is located below the limiting block.
[0051] When the core 22 starts to move upward relative to the upper block 21-1, the core 22 drives the driving block to move upward synchronously, and the limiting block is limited by the limiting slot, so that when the core 22 starts to move upward, the height of the upper block 21-1 remains unchanged, prompting the locking block to be pulled out of the locking slot.
[0052] When the core 22 starts to drive the upper block 21-1 to move upward, the driving block moves upward with the core 22, and the inclined driving surface at the top of the driving block starts to squeeze the limit block. The limit block is displaced in the direction away from the locking block by squeezing the retraction spring. When the top of the core 22 starts to abut against the bottom of the traction rod 21-3, the locking block is driven by the core 22 to move upward synchronously, so that the inclined surface at the top of the locking block starts to abut against the inner top wall of the limit slot. The locking block is lifted and moved upward continuously by the core 22, and the inclined surface at the top of the locking block starts to squeeze the limit block until the locking block is completely moved out of the limit slot. In this way, the core 22 drives the upper block 21-1 to move upward together. When the locking block is completely moved above the limit block, the limit block is reset under the elastic force of the retraction spring.
[0053] When the core 22 drives the upper push block 21-1 to move downward together with the lower mold 1 to form a complete casting cavity, the upper push block 21-1, the driving block and the locking block are driven by the core 22 to move downward synchronously. When the bottom inclined guide surface of the driving block begins to abut against the top of the limit block, the limit block obtains the downward space by squeezing the limit block, and the locking block follows and moves downward synchronously and begins to abut against the top of the limit block. As the core 22 continues to move downward, the locking block is pulled and gradually aligned with the limit slot until the locking block is stuck in the limit slot again. At this time, there is still a distance between the core 22 and the lower mold 1. The core 22 continues to move downward, and the upper push block 21-1 is limited by the locking block and cannot move downward anymore. When the core 22 is fitted with the lower mold 1, the bottom of the core 22 is flush with the bottom of the upper push block 21-1.
[0054] In order to enable the core 22 to drive the traction frame 11-2 and the lower support block 11-1 to move upward synchronously, the top of the traction frame 11-2 is provided with a synchronous connecting frame, and a synchronous connecting piece is installed in the synchronous connecting frame.
[0055] The synchronous connecting piece comprises a contraction spring and a synchronous connecting block. The synchronous connecting block is slidably and penetrates the synchronous connecting frame. The contraction spring is abutted and installed between the inner wall of the synchronous connecting frame and the synchronous connecting block.
[0056] One end of the core 22 adjacent to the traction rod 21 - 3 is provided with a snap-fit block, the snap-fit block having a groove body matching the synchronous connection block, and the snap-fit block is installed on the up and down displacement path of the synchronous connection block.
[0057] The top end of the unlocking guide frame is provided with an unlocking guide plate, which is fixedly mounted on the outer end of the unlocking guide frame and is located on the up and down displacement path of the raised column.
[0058] The side wall of the synchronous connecting frame adjacent to the lower mold 1 is penetrated by a through hole, and the side wall of the synchronous connecting frame adjacent to the through hole is provided with a movable groove. The synchronous connecting block is installed through the through hole, and one end of the telescopic spring abuts against the inner wall of the synchronous connecting frame facing away from the lower mold 1, and the other end of the telescopic spring abuts against the end of the synchronous connecting block located in the synchronous connecting frame. The end of the synchronous connecting block extending out of the through hole has a clamping guide surface, and the side wall of the synchronous connecting block has a protruding column, which is slidably installed in the movable groove.
[0059] In the initial state, the protruding column is squeezed by the unlocking guide plate to the outer end of the movable groove.
[0060] Specifically, when the core 22 starts to drive the lower push piece 11 to move upward, the locking block starts to abut against the bottom end of the synchronous connection block as the core 22 moves upward, and drives the synchronous connection block to move upward. At this time, the raised column that is limited by the unlocked guide plate is unlocked and limited, so that the synchronous connection block can be pushed by the telescopic spring and inserted into the groove body of the locking block, so that the subsequent downward movement of the core 22 can drive the traction frame 11-2 and the lower push block 11-1 to move downward synchronously.
[0061] like Figure 4 As shown, in one embodiment, the casting clamp 3 includes a bracket 33 and a driving spring 34, and the traction frame 11-2 has a connecting plate 11-21 (see Figure 3 ), the bracket 33 is slidably installed on the top of the connecting plate 11-21, and the driving spring 34 is installed on the top of the bracket 33.
[0062] The top of the bracket 33 is provided with a track plate 33-1, and the track plate 33-1 is provided with a clamping jaw driving track 33-2. The upper clamping jaw 31 is slidably installed on the clamping jaw driving track 33-2. The side wall of the upper clamping jaw 31 is provided with a slide column 31-1, and the slide column 31-1 is slidably installed in the clamping jaw driving track 33-2. One end of the driving spring 34 abuts against the inner wall of the track plate 33-1, and the other end thereof abuts against the upper clamping jaw 31.
[0063] In this embodiment, the clamping claw driving track 33-2 has a retracting portion 33-21, an upward driving portion 33-22 and a limiting portion 33-23, and the retracting portion 33-21, the upward driving portion 33-22 and the limiting portion 33-23 are arranged along the traction rod 21-3 (see Figure 3 ) to the direction of the upper clamping jaw 31 are arranged in sequence.
[0064] The bracket 33 has a sliding claw 35 at the bottom end near the limiting portion 33 - 23 . The lower clamping plate 32 has a sliding track 32 - 1 . The sliding claw 35 is slidably located in the sliding track 32 - 1 .
[0065] Specifically, in the process of the core 22 moving up and separating from the lower mold 1, the upper clamping jaw 31, which is now released from the limit, is driven by the driving spring 34 to abut against the core 22. When the core 22 moves up to a certain distance, the upper clamping jaw 31 is engaged with the top of the copper casting and the lower mold 1 by the driving spring 34. In this process, the upper clamping jaw 31 is pushed by the driving spring 34 in the clamping jaw driving track 33-2 from the retraction part 33-21 through the upward driving part 33-22 into the limiting part 33-23. At this time, the position of the upper clamping jaw 31 relative to the bracket 33 is locked.
[0066] like Figure 5 As shown, in one embodiment, the top of the bracket 33 also has a clamping claw limiter 36 (see Figure 4 ), the clamping jaw limiting member 36 includes a clamping jaw limiting block 36-1, a lifting spring 36-2 and a translation spring 36-3, and a group of side walls of the track plate 33-1 away from the unloading platform 4 are provided with a lifting limiting groove 33-11 and a translation limiting groove 33-12. The top end of the clamping jaw limiting block 36-1 is installed in the lifting limiting groove 33-11, the top end of the lifting spring 36-2 abuts against the inner top wall of the lifting limiting groove 33-11, and the bottom end of the lifting spring 36-2 abuts against the top end of the clamping jaw limiting block 36-1.
[0067] The bottom end of the clamping jaw limit block 36-1 is installed in the translation limit slot 33-12, one end of the translation limit slot 33-12 abuts against the inner wall of the translation limit slot 33-12 away from the unloading platform 4, and the other end of the translation limit slot 33-12 abuts against the side wall of the clamping jaw limit block 36-1 away from the unloading platform 4.
[0068] The bottom end of the clamping jaw limit block 36 - 1 adjacent to the upward driving portion 33 - 22 has a retraction driving inclined surface 36 - 11 , the top end of the clamping jaw limit block 36 - 1 has a release driving surface 36 - 12 , and the core 22 has a release driving block 22 - 2 .
[0069] When the bottom of the core 22 is about to fit into the top of the lower mold 1 , the release drive is released by squeezing the release drive surface 36 - 12 to drive the clamping jaw limit block 36 - 1 to move out of the clamping jaw drive track 33 - 2 .
[0070] In this embodiment, the material moving member 5 includes a material moving plate 51, a material loosening plate 52 and a material moving frame 53 (see Figure 3 and Figure 4 ), one end of the material moving plate 51 is fixedly mounted on the side wall of the lower mold 1, and the other end thereof is fixedly mounted on the material unloading platform 4, the material loosening plate 52 is fixedly mounted on the material unloading platform 4, the material moving rack 53 is slidably mounted on the material moving plate 51, and the material moving rack 53 is slidably mounted on the material moving plate 51.
[0071] In this embodiment, a locking drive rod 51-1 is fixedly installed on the top of the end of the material moving plate 51 away from the lower mold 1, and a locking drive column 31-2 is provided at the bottom of the upper clamping jaw 31 (see Figure 4 ).
[0072] The loosening plate 52 has an access track 52-1, a loosening driving surface 52-2 and a clamping claw locking track 52-3 (see Figure 3 ), the access track 52-1, the loosening driving surface 52-2 and the clamping claw locking track 52-3 are arranged in sequence along the direction from the lower mold 1 to the unloading table 4.
[0073] Specifically, in the process of pulling the upper clamping claw 31 and the lower clamping plate 32 to move toward the unloading platform 4, like Figure 6 As shown, in one embodiment, the surface of the lower clamping plate 32 adjacent to the unloading platform 4 has a T-shaped guide column 32-2 (see Figure 4 ), the material moving rack 53 includes a material moving slider 53-1, an upward guide plate 53-2, a translation drive plate 53-3, a downward locking plate 53-4, an offset drive plate 53-5 and a reset guide plate 53-6, and the upward guide plate 53-2 is fixedly installed on the top of the material moving slider 53-1.
[0074] The translation driving plate 53-3 includes a long driving plate 53-31 and a short driving plate 53-32. The long driving plate 53-31 is fixedly mounted on the top of the upward guide plate 53-2, and the short driving plate 53-32 is fixedly mounted on the material moving slider 53-1.
[0075] The downward locking plate 53-4 is set in a "U" shape, one end of the downward locking plate 53-4 is fixedly installed on the translation driving plate 53-3, and one end of the downward locking plate 53-4 is fixedly installed on the bottom end of the offset driving plate 53-5.
[0076] The reset guide plate 53-6 is slidably mounted on the top of the upward guide plate 53-2. The reset guide plate 53-6 can be displaced along the length direction of the translation drive plate 53-3 relative to the upward guide plate 53-2.
[0077] In the initial state, the top end of the reset guide plate 53 - 6 abuts against the bottom end of the short driving plate 53 - 32 .
[0078] Preferably, the material moving slider 53 - 1 has a traction handle.
[0079] In this embodiment, the top of the upward guide plate 53-2 connected to the reset guide plate 53-6 has a spring seat 53-21, and the top of the spring seat 53-21 is flush with the bottom of the short drive plate 53-32. The reset guide plate 53-6 includes an arc plate 53-61 and a strip plate 53-62. The strip plate 53-62 is fitted and slidably installed on the top of the spring seat 53-21, and the bottom end of the arc plate 53-61 is fixedly connected to the top of the strip plate 53-62.
[0080] The bottom end of the strip plate 53-62 has a sliding limit block 53-63, which is slidably installed in the spring seat 53-21. The sliding limit block 53-63 is away from the side wall of the arc plate 53-61 and is abutted against the movable spring 53-22, and the other end of the movable spring 53-22 abuts against the inner wall of the outer end of the spring seat 53-21.
[0081] In the initial state, the top end of the strip plate 53 - 62 abuts against the bottom end of the short driving plate 53 - 32 .
[0082] Specifically, in the process of the core 22 driving the traction frame 11-2 and the lower support block 11-1 to move upward, the traction frame 11-2 drives the bracket 33, the upper clamping jaw 31 and the lower clamping plate 32 to move upward synchronously through the connecting plate 11-21. When the height of the lower clamping plate 32 moves to a height higher than the top of the lower mold 1, the T-shaped guide column 32-2 on the lower clamping plate 32 begins to be between the two groups of upward guide plates 53-2. As the lower clamping plate 32 continues to move upward, the T-shaped guide column 32-2 begins to enter between the long drive plate 53-31 and the short drive plate 53-32. The T-shaped guide column 32-2 is driven toward the direction of the copper casting during the upward movement, so that the lower clamping plate 32 is gradually moved to the bottom of the copper casting, so that the lower clamping plate 32 and the upper clamping jaw 31 can clamp the copper casting together.
[0083] As the core 22 drives the traction frame 11-2 and the lower retaining block 11-1 downward, separating the lower retaining block 11-1 from the copper casting, the traction frame 11-2 drives the bracket 33, the upper clamping jaw 31, and the lower clamping plate 32 to move downward synchronously through the connecting plate 11-21. After the bottom of the lower clamping plate 32 abuts the top of the lower mold 1, the bracket 33, the upper clamping jaw 31, the lower clamping plate 32, and the copper casting stop moving downward, while the lower retaining block 11-1 continues to move downward, allowing the lower retaining block 11-1 to be separated from the copper casting. In this process, the lower clamping plate 32 moves downward into the bottom end of the downward locking plate 53-4, locking the position of the lower clamping plate 32 relative to the copper casting.
[0084] Subsequently, by pulling the traction handle, the traction handle drives the material moving frame 53 to move toward the unloading platform 4. The material moving frame 53 pulls the lower clamping plate 32, the bracket 33, the upper clamping jaw 31, and the copper casting together through the T-shaped guide column 32-2. During this process, the bottom end of the upper clamping jaw 31 first enters the access track 52-1. When the bottom end of the upper clamping jaw 31 abuts the loose material driving surface 52-2, the upper clamping jaw 31 begins to be driven upward, causing the clamping jaw of the upper clamping jaw 31 to begin to separate from the copper casting. The material moving frame 53 continues to move. When the bottom end of the clamping jaw of the upper clamping jaw 31 is higher than the top height of the copper casting, the copper casting is no longer driven by the upper clamping jaw 31 to move on the unloading platform 4.
[0085] The material transfer rack 53 is continuously moved to drive the upper clamping jaw 31 into the clamping jaw locking track 52-3. Subsequently, the locking drive column 31-2 on the upper clamping jaw 31 begins to abut against the locking drive rod 51-1. As the upper clamping jaw 31 continues to move along the clamping jaw locking track 52-3, the locking drive column 31-2 begins to be pushed by the locking drive rod 51-1 to move away from the copper casting. During this process, the slide post 31-1 of the upper clamping jaw 31 moves from the limiting portion 33-23 to the retraction portion 33-21 via the upward driving portion 33-22. When the upper clamping jaw 31 enters the retraction portion 33-21, the slide post 31-1 squeezes the clamping jaw limiting block 36-1 to cause the clamping jaw limiting block 36-1 to move upward to obtain a displacement path. When the slide post 31-1 moves to the retraction portion 33-21, the clamping jaw limiting block 36-1, which has been pushed back to its original position by the lifting spring 36-2, is blocked between the retraction portion 33-21 and the upward retraction portion 33-21, preventing the upper clamping jaw 31 from returning to its original position. Subsequently, the traction handle is pulled in the opposite direction to move the lower clamping plate 32, the bracket 33, and the upper clamping jaw 31 back to the connecting plate 11-21.
[0086] The core 22 is driven upward again, which in turn drives the traction frame 11-2 upward. The traction frame 11-2 drives the lower clamping plate 32, bracket 33, and upper clamping jaw 31 upward synchronously via the connecting plate 11-21. During the upward movement, the T-shaped slide 31-1 on the lower clamping plate 32 is driven by the offset drive plate 53-5 to partially reset horizontally. The core 22 is then driven downward, driving the lower clamping plate 32, bracket 33, and upper clamping jaw 31 downward. During this process, the T-shaped slide 31-1 presses the reset guide plate 53-6, driving the reset guide plate 53-6 to move along the spring seat 53-21, separating the strip plate 53-62 from the short drive plate 53-32. This allows the T-shaped slide 31-1 to move between the long drive plate 53-31 and the short drive plate 53-32, facilitating the reset of the lower clamping plate 32 by downward movement.
[0087] like Figure 7 and Figure 8As shown, in one embodiment, a vertical traction plate 11-22 is fixedly mounted on the connecting plate 11-21, and the bracket 33 has a horizontal limiting hole 33-3 at the bottom end adjacent to the traction frame 11-2, and the shape of the horizontal limiting hole 33-3 matches the shape of the vertical traction plate 11-22.
[0088] The lower clamping plate 32 has a horizontal latch 32 - 3 at one end facing away from the lower mold 1 , and the bracket 33 and the vertical traction plates 11 - 22 both have a socket that matches the shape of the horizontal latch 32 - 3 .
[0089] It should be noted that the bottom end of the upper clamping jaw 31 has a movable hole, which is a vertically arranged rectangle, so that the upper clamping jaw 31 can move up and down relative to the horizontal pin 32-3 and move along the clamping jaw drive track 33-2.
[0090] Specifically, when the lower clamping plate 32 moves to the bottom of the copper casting, the lower clamping plate 32 drives the horizontal pin 32-3 to be removed from the sockets of the bracket 33 and the vertical traction plate 11-22 to release the position locking effect on the bracket 33 and the traction frame 11-2.
[0091] When the traction handle is pulled to drive the lower clamping plate 32 and the upper clamping claw 31 to move toward the unloading platform 4, the lower clamping plate 32 drives the bracket 33 to move synchronously, so that the bracket 33 is removed from the vertical traction plate 11-22, and the limit on the bracket 33 and the connecting plate 11-21 is completely released.
