Description

Technical Field

[0001] This application relates to the field of power equipment manufacturing technology, specifically to an automated demolding integrated device for the production of high-voltage switch insulation components. Background Technology

[0002] Pot-type insulators are key insulating components in switchgear (GIS), widely used in high-voltage switchgear to support conductors and provide electrical isolation. Pot-type insulators are typically formed in a mold using a casting process. After forming, the insulators need to be removed from the mold for further processing.

[0003] In the current production process, the demolding of basin-type insulators is mostly done manually. The specific process is as follows: First, operators use hoisting equipment to move the mold containing the basin-type insulator to the work area; then, workers use wrenches and other tools to disassemble the multiple locking screws on the mold one by one; next, they use pry bars or special tools to pry open the left and right halves of the mold; finally, they manually knock the basin-type insulator out of the mold. Because the entire demolding process involves numerous steps, manual operation is time-consuming, inefficient, and carries safety risks such as component slippage and damage, and injury to operators. Furthermore, the demolding process, including disassembling the screws, prying open the mold, and removing the basin-type insulator, requires a high degree of synchronization, often requiring multiple workers to cooperate, which can easily lead to problems such as thread wear and insulator surface damage. In addition, the precision of manual operation is difficult to maintain consistently, making it difficult to meet product consistency requirements in large-scale, mass production. Summary of the Invention

[0068] This embodiment provides an automated demolding integrated device for the production of high-voltage switch insulation components, such as... Figure 1 and Figure 2 As shown, the automated demolding integrated device includes a base 1, a support fixture 2, a nut locking fixture 3, a screw disassembly fixture 4, a mold splitting fixture 5, a demolding fixture 6, and a robotic arm 7. The support fixture 2 is mounted on the base 1 and is used to support and position the mold 8 with the basin-type insulator. Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, the nut locking fixture 3 is slidably disposed on the base 1. The nut locking fixture 3 includes a first drive assembly and a locking sleeve 33. The locking sleeve 33 is connected to the first drive assembly and can move along the first horizontal direction P under the drive of the first drive assembly, so that the locking sleeve 33 can engage with the locking nut 82 on the mold 8 from one side of the mold 8. Figure 7 and Figure 8 As shown, the screw removal fixture 4 includes a first connecting seat 40 and a removal unit disposed on the first connecting seat 40. The removal unit includes an electric screwdriver 41 and a gripper assembly 42. The electric screwdriver 41 and the gripper assembly 42 cooperate to screw and remove the locking screw 83 on the mold 8 from the other side of the mold 8 along the first horizontal direction. The locking screw 83 is locked to the locking nut 82 on the mold 8.

[0069] By combining the nut locking fixture 3 and the screw disassembly work, the automatic disassembly of the locking screw 83 on the mold 8 can be achieved.

[0070] Combination Figure 12As shown, in this embodiment, the mold splitting fixture 5 is disposed on one side of the support fixture 2. The mold splitting fixture 5 includes a pushing unit 50 and a docking assembly. The docking assembly is used to drive the pushing unit 50 to extend into the space between two sets of docking blocks 84 on the mold 8. The pushing unit 50 is used to push the two sets of docking blocks 84 from between the two sets of docking blocks 84 in opposite directions to split the mold 8 into a left half mold 80 and a right half mold 81. Thus, the mold splitting fixture 5 can open the mold 8 into a left half mold 80 and a right half mold 81, exposing the basin-type insulator located inside the mold 8.

[0071] Combination Figure 16 As shown, the demolding fixture 6 in this embodiment includes a second connecting seat 60 and a demolding unit disposed on the second connecting seat 60. The demolding unit includes a second driving assembly 62 and a transmission screw 61 that is driven by the second driving assembly 62 and is rotatable. The transmission screw 61 is configured to fit into the screw hole on the basin insulator and can drive the basin insulator to disengage from the mold 8 through rotation. Thus, the basin insulator can be removed from the mold 8 by the demolding fixture 6.

[0072] In this embodiment, the robotic arm 7 is used to drive the screw disassembly fixture 4 and the demolding fixture 6 to move by docking with the first connecting seat 40 and the second connecting seat 60, respectively. The robotic arm 7 can be used to grasp and move the screw disassembly fixture 4 and the demolding fixture 6, thereby facilitating the spatial arrangement of the nut locking fixture 3, the screw disassembly fixture 4, the mold splitting fixture 5, and the demolding fixture 6, and avoiding interference between the various fixtures during the demolding operation.

[0073] The automated demolding device provided in this embodiment enables automatic demolding of the basin-type insulator relative to the mold 8, significantly improving work efficiency and eliminating safety risks. Furthermore, this automated demolding device ensures product consistency and is suitable for large-scale, mass production.

[0074] Combination Figure 2 , Figure 3 and Figure 4As shown, the first driving component in this embodiment includes a first mounting base 30, a first linear driving mechanism 31, and multiple sets of rotary driving units 32. The multiple sets of rotary driving units 32 are disposed on the first mounting base 30 and correspond one-to-one with the locking nuts 82 on the mold 8. Locking sleeves 33 are disposed at the output end of the rotary driving units 32. Since multiple sets of locking screws 83 and locking nuts 82 are used for locking on the mold 8, to simplify the operation process, this embodiment provides a first mounting base 30 and simultaneously provides the same number of rotary driving units 32 as the number of locking nuts 82 on the mold 8. This allows the rotary driving units 32 and the locking sleeves 33 disposed at their output ends to correspond one-to-one with the locking nuts 82, enabling all locking nuts 82 on the mold 8 to be positioned in one operation. Specifically, in this embodiment, the first mounting base 30 is reciprocally slidably disposed on the base 1 along the first horizontal direction P. The first linear driving mechanism 31 is connected to the first mounting base 30 and is used to drive the first mounting base 30 to slide relative to the mold 8.

[0075] When the specifications and types of mold 8 are different, the distribution positions of its locking nuts 82 may differ. Therefore, it is necessary to change the size of the first mounting base 30 and the distribution position of the rotary drive unit 32 on the first mounting base 30 accordingly. To facilitate the replacement and assembly of the nut locking fixture 3 for different molds 8, in this embodiment, the nut locking fixture 3 is designed as a separate unit, specifically as follows: Figure 2 and Figure 3 As shown, the first mounting base 30 and multiple sets of rotary drive units 32 disposed on the first mounting base 30 in the nut locking fixture 3 are integrated as a whole, and a first lifting ring 300 is provided on the first mounting base 30. Before demolding, a suitable nut locking fixture 3 is selected according to the type of mold 8. The first linear drive mechanism 31 in the nut locking fixture 3 includes a second pneumatic slide 310 and a second support base plate 311. The second pneumatic slide 310 and the second support base plate 311 are pre-installed on the base 1. When replacing the first mounting base 30 and the rotary drive unit 32 as a whole, the first linear drive mechanism 31 does not need to be replaced, which can reduce the difficulty of replacement and assembly.

[0076] Furthermore, in this embodiment, the support fixture 2 includes a first support seat 20 fixedly disposed on the base 1 and a second support seat 21 slidably disposed on the base 1. The first support seat 20 is used to position the left half mold 80 in the mold 8, and the second support seat 21 is used to position the right half mold 81 in the mold 8. Thus, when the left half mold 80 and the right half mold 81 are relatively pushed apart, the right half mold 81 can slide relative to the left half mold 80. Specifically, in this embodiment, a first pneumatic slide 10 and a first support base plate 11 are provided on the base 1. The second support seat 21 in the support fixture 2 is fixedly disposed on the first support base plate 11, and the aforementioned second pneumatic slide 310 and second support base plate 311 are also disposed on the first support base plate 11. Figure 10 and Figure 11 As shown, the mold 8 includes a left half mold 80 and a right half mold 81. A left support base 800 is provided below the left half mold 80, and a right support base 810 is provided below the right half mold 81. A second lifting ring 85 is provided on both the left half mold 80 and the right half mold 81. The mold 8 to be demolded can be hoisted to the support fixture 2 through the second lifting ring 85. Then, the left support base 800 is locked and fixed to the first support seat 20 by screws, and the right support base 810 is locked and fixed to the second support seat 21 by screws.

[0077] like Figure 4 , Figure 5 and Figure 6As shown, the rotary drive unit 32 in this embodiment includes a swing cylinder 320, a brake 3200, and a transmission mechanism. The transmission mechanism includes a drive shaft 321, a connecting sleeve 322, a first elastic element 323, and a first limiting structure. The drive shaft 321 is connected to the output end of the swing cylinder 320. The connecting sleeve 322 is keyed to the drive shaft 321 and can slide axially relative to the drive shaft 321. The first elastic element 323 is disposed between the connecting sleeve 322 and the drive shaft 321 and applies pressure to the connecting sleeve 322, causing it to tend to move away from the drive shaft 321. The first limiting structure is disposed on the drive shaft 321 and is used to prevent the connecting sleeve 322 from disengaging from the drive shaft 321. A locking sleeve 33 is fixedly installed on the connecting sleeve 322. The brake 3200 is used to brake the locking sleeve 33 after it engages with the locking nut 82. With the above structural design, when the locking nut 82 needs to be locked by the nut locking fixture 3, the first linear drive mechanism 31 drives the first mounting base 30 and the rotary drive unit 32 to move towards the mold 8 until the locking sleeve 33 abuts against the locking nut 82. Due to the presence of the first elastic element 323, rigid impact between the locking sleeve 33 and the locking nut 82 is avoided. Then, the swing cylinder 320 drives the locking sleeve 33 to rotate. While rotating, the locking sleeve 33 is also subjected to the elastic force applied by the first elastic element 323. When the locking sleeve 33 rotates to align with the locking nut 82, it automatically engages with the locking nut 82 under the pressure of the first elastic element 323, achieving docking between the locking sleeve 33 and the locking nut 82. Afterwards, the brake 3200 controls the locking sleeve 33 to stop rotating and locks the locking nut 82, ensuring that the locking nut 82 will not rotate during the subsequent tightening of the locking screw 83 using the screw removal fixture 4.

[0078] In this embodiment, the keyed fit between the drive shaft 321 and the connecting sleeve 322 ensures that they can both slide relative to each other and generate transmission along the circumference. Specifically, in this embodiment, the first elastic element 323 is a compression spring, and a protruding structure is provided on the drive shaft 321. The connecting sleeve 322 includes a first ring sleeve 3220 and a second ring sleeve 3221, wherein the first ring sleeve 3220 is a spline sleeve. The outer diameters of both the first ring sleeve 3220 and the second ring sleeve 3221 are larger than the outer diameter of the drive shaft 321. The first elastic element 323 is sleeved on the outside of the drive shaft 321, with one end of the first elastic element 323 abutting against the protruding structure and the other end abutting against the first ring sleeve 3220. The first limiting structure includes a limiting circular plate 324 provided at the end of the drive shaft 321 and an abutting inclined surface 32200 formed on the first ring sleeve 3220. Specifically, the first ring sleeve 3220 is keyed to the drive shaft 321. During assembly, the two are first keyed together, and then the limiting circular plate 324 is locked and fixed to the end of the drive shaft 321 using screws. The outer edge of the limiting circular plate 324 forms a limiting part 3240 that can cooperate with the abutting inclined surface 32200 provided on the first ring sleeve 3220. The limiting part 3240 and the abutting inclined surface 32200 cooperate to prevent the first ring sleeve 3220 from falling off the drive shaft 321. Then, the second ring sleeve 3221 is locked and fixed to the first ring sleeve 3220 with screws. The inner diameter of the second ring sleeve 3221 is designed to be larger than that of the limiting circular plate 324, so that the first ring sleeve 3220 and the second ring sleeve 3221 can slide relative to the drive shaft 321.

[0079] Combination Figure 7 , Figure 8 and Figure 11 As shown, the disassembly unit in this embodiment includes an electric screwdriver 41 and a gripper assembly 42. After locking the locking nut 82 using the nut locking fixture 3, the screw disassembly fixture 4 can be moved by the robotic arm 7 to mate the electric screwdriver 41 with the locking screw 83. Then, the electric screwdriver 41 is used to tighten the locking screw 83, removing the locking screw 83 from the mold 8. The electric screwdriver 41 is an existing product, and its structure and working principle will not be described in detail here.

[0080] The gripper assembly 42 in this embodiment includes a first linear actuator 420 disposed on the first connecting seat 40, a bending frame 421 driven by the first linear actuator 420 and capable of moving axially along the locking screw 83, and a pneumatic gripper 422 disposed on the bending frame 421. The pneumatic gripper 422 has multiple circumferentially distributed gripper portions, which surround the outer side of the front section of the electric screw gun 41. With the above structural design, when the locking screw 83 is screwed to the point of separation from the locking nut 82 but not yet completely detached from the mold 8, the first linear actuator 420 can be used to drive the pneumatic gripper 422 to move forward, and then the pneumatic gripper 422 can be controlled to work so that the gripper portions cooperate to clamp and fix the locking screw 83. Afterwards, the robotic arm 7 drives the screw disassembly fixture 4 to move as a whole to the unloading position to lower the locking screw 83.

[0081] As mentioned earlier, the molds 8 used for producing different pot-type insulators differ in size, resulting in differences in the positions of the insulating nuts and insulating screws. To improve the adaptability of the screw disassembly fixture 4, this embodiment has two sets of disassembly units arranged at intervals. The screw disassembly fixture 4 also includes a first adjusting mechanism 43 disposed on the first connecting seat 40. The first adjusting mechanism 43 is connected to the disassembly unit and is used to adjust the distance between the two sets of disassembly units by driving the two sets of disassembly units to move relative to each other. Through the above structural design, the position of the disassembly unit in the vertical direction can be adjusted by the robotic arm 7, and the distance between the two sets of disassembly units can be adjusted by the first adjusting mechanism 43, so that the disassembly unit can adapt to the position of the locking screw 83 on different molds 8. The disassembly unit also includes an adapter 45, on which the electric screw gun 41 and the gripper assembly 42 are all mounted.

[0082] Specifically, in this embodiment, the first adjusting mechanism 43 is a cylinder. The first adjusting mechanism 43 is fixedly mounted on the first connecting seat 40, and its output end is fixedly connected to the adapter 45 in one of the disassembly units. That is, one set of disassembly units can translate under the drive of the first adjusting mechanism 43, while the other set of disassembly units remains fixed relative to the first connecting seat 40. Correspondingly, in this embodiment, a first guide rail 44 is provided on the first connecting seat 40 for one set of disassembly units to ensure the stability of the disassembly units during translation.

[0083] Combination Figure 1 , Figure 9 , Figure 12 and Figure 13As shown, the mold splitting fixture 5 in this embodiment also includes a frame 51. The docking assembly includes a horizontal drive mechanism 53 disposed on the frame 51 and an adapter frame 52 disposed on the output end of the horizontal drive mechanism 53. The horizontal drive mechanism 53 is used to drive the adapter frame 52 to reciprocate along the second horizontal direction S. The push unit 50 is disposed on the adapter frame 52, and the second horizontal direction S is perpendicular to the first horizontal direction P. By driving the push unit 50 to move along the second horizontal direction S through the horizontal drive mechanism 53, the push unit 50 is controlled to retract to avoid the placement operation of the mold 8. By controlling the push unit 50 to move closer to the mold 8, the push unit 50 can be inserted between the two sets of docking blocks 84 on the mold 8. Then, by using the push unit 50 to act on the two sets of docking blocks 84 in the opposite direction, the left half mold 80 and the right half mold 81 can be pushed apart.

[0084] In this embodiment, two sets of mold disassembly fixtures 5 are arranged on both sides of the mold 8. The simultaneous operation of the two sets of mold disassembly fixtures 5 can ensure the symmetry of the pushing action.

[0085] Combination Figure 14 As shown, the docking assembly in this embodiment also includes a guide unit disposed on the adapter frame 52. The guide unit includes a guide block 54, and a pushing unit 50 is fixedly installed on the guide block 54. The guide block 54 is used to cooperate with one of the docking blocks 84 to guide the pushing unit 50 to extend between the two sets of docking blocks 84. In practical applications, due to manufacturing or assembly errors, the pushing unit 50 may not be able to fully align with the space between the two sets of docking blocks 84 in some cases, which may cause the pushing unit 50 to interfere with the docking blocks 84 and fail to extend properly between the two sets of docking blocks 84. To avoid this situation, in this embodiment, the docking block 84 is designed to move elastically relative to the adapter frame 52, and the guide block 54 is provided to guide and position the docking block 84. Specifically, in this embodiment, the guide block 54 is provided with a side abutment portion 540. The thickness of the guide block 54 is configured such that when the side abutment portion 540 abuts against the side of the docking block 84 on one side, the push unit 50 fixed to the guide block 54 is positioned between the two docking blocks 84 along the first horizontal direction P.

[0086] The guiding unit also includes a second elastic member 57 and a second limiting structure disposed between the guide block 54 and the adapter frame 52. The second elastic member 57 applies pressure to the guide block 54 to cause the guide block 54 to tend to move away from the adapter frame 52. The second limiting structure is used to prevent the guide block 54 from disengaging from the adapter frame 52. Figure 14As shown, a guide slope is also provided at the end of the guide block 54 facing the mold 8. When the push unit 50 interferes with the docking block 84, it can slide and contact the docking block 84 through the guide slope of the guide block 54, and the second elastic element 57 is used to adaptively move, so that the guide block 54 drives the push unit 50 to translate along the first horizontal direction P until the push unit 50 is completely aligned and extends between the two sets of docking blocks 84.

[0087] In this embodiment, the pushing unit 50 is a flat hydraulic cylinder. Flat hydraulic cylinders have the advantage of occupying little space in a specific direction, making them suitable for application scenarios where the distance between the two sets of mating blocks 84 on the mold 8 cannot be too large. By the flat hydraulic cylinder acting on the two sets of mating blocks 84 in opposite directions, the left half mold 80 and the right half mold 81 can be pushed apart. During this process, the first electric cylinder platform synchronously drives the first support base plate 11 to apply force. After the left half mold 80 and the right half mold 81 separate, the second support seat 21 located on the first support base plate 11 and the right half mold 81 located on the second support seat 21 can be moved apart.

[0088] Combination Figure 13 and Figure 15 As shown, the guiding unit in this embodiment further includes a mounting frame 55 disposed on the adapter frame 52. The mounting frame 55 forms a cavity, and a second elastic member 57 is disposed within the cavity, with both ends abutting against the mounting frame 55 and the guide block 54, respectively. Thus, the second elastic member 57 can apply pressure to the guide block 54. In this embodiment, the second elastic member 57 is a spring tube. Additionally, the second limiting structure in this embodiment includes a guide rod 56 slidably disposed on the mounting frame 55 and a limiting block 560 disposed on the guide rod 56 at one end away from the guide block 54. One end of the guide rod 56 is fixedly installed on the guide block 54. To ensure the stability of the guide rod 56's sliding movement, a sleeve 550 is also fixedly installed within the mounting frame 55 in this embodiment, and the guide rod 56 is slidably disposed within the sleeve 550. Thus, the second elastic member 57 can apply pressure to the guide block 54, and the limiting block 560 abutting against one end of the mounting frame 55 can prevent the guide rod 56 and the guide block 54 fixedly installed with the conduit from disengaging from the mounting frame 55.

[0089] Furthermore, this embodiment also designs the position guidance of the pushing unit 50 in the height direction. Specifically, the guide block 54 in this embodiment is provided with a guide groove 541 facing one side of the docking block 84. The guide block 54 is configured such that when the inner wall of the guide groove 541 abuts against the docking block 84 on one side, the pushing unit 50 fixed to the guide block 54 is positioned vertically between the two sets of docking blocks 84. Meanwhile, as... Figure 12 and Figure 13As shown, the docking assembly also includes a slide rail structure disposed between the mounting frame 55 and the adapter frame 52, with the mounting frame 55 slidably disposed on the adapter frame 52 via the slide rail structure. To distinguish it from other slide rails in this embodiment, the slide rail structure disposed between the mounting frame 55 and the adapter frame 52 is referred to as the second guide slide rail 520 in this embodiment.

[0090] Before pushing the push unit 50 into the space between the two sets of docking blocks 84, the push unit 50 is held at a certain height. After the inner wall of the guide groove 541 contacts the docking block 84, the cooperation between the inner wall of the guide groove 541 and the docking block 84 can guide the mounting bracket 55, the guide block 54 and the push unit 50 as a whole to rise a certain distance along the second guide rail 520 in the height direction to precisely adjust the height position of the push unit 50.

[0091] As mentioned above, in this embodiment, a set of mold splitting fixtures 5 are respectively provided on both sides of the mold 8. Furthermore, each set of mold splitting fixtures 5 in this embodiment is provided with two sets of guide units. The two sets of guide units are distributed vertically at intervals, and the mold splitting fixture 5 also includes a lifting drive mechanism 58. The lifting drive mechanism 58 is used to connect with the guide unit located on the upper side and to drive the guide unit located on the upper side to move vertically between a first position and a second position, wherein the second position is higher than the first position. Correspondingly, two sets of push units 50 are also provided, and the two sets of push units 50 are correspondingly arranged on the two sets of guide units.

[0092] The positions of the upper docking blocks 84 on different molds 8 may vary. The lifting drive mechanism 58 allows the two sets of guiding units and the pushing unit 50 to adapt to different molds 8, increasing the applicability of the mold disassembly fixture 5. The upper guiding unit can be driven to a first position or a second position via the lifting drive mechanism 58. The first and second positions refer to predetermined height positions adapted to the upper docking blocks 84 in different molds 8.

[0093] In this embodiment, the lower guide unit and the pusher unit 50 disposed on the guide unit can be positioned at the bottom end of the second guide rail 520 by their own weight. After the inner wall of the guide groove 541 contacts the docking block 84, the interaction between the inner wall of the guide groove 541 and the docking block 84 can drive the lower guide unit to move slightly upward along the second guide rail 520. After the upper guide unit and the pusher unit 50 disposed on the guide unit are driven to the first or second position by the lifting drive mechanism 58, in order to enable them to also achieve position adjustment in the height direction, the mold disassembly fixture 5 in this embodiment also includes a support cylinder 59 disposed on the adapter frame 52. The output end of the support cylinder 59 is configured to switch between an extended position and a retracted position. When the output end of the support cylinder 59 is in the extended position, it can support the upper guide unit. Specifically, as shown... Figure 13 As shown, the mounting bracket 55 of the guide unit is provided with two sets of guide rods 56 and a limiting block 560 installed on the guide rods 56. When the guide unit is in the first position, the output end of the support cylinder 59 abuts against the limiting block 560 on the upper side and supports the guide unit through the limiting block 560 on the upper side. Similarly, when the guide unit is in the second position, the output end of the support cylinder 59 abuts against the limiting block 560 on the lower side and supports the guide unit through the limiting block 560 on the lower side.

[0094] With the above structural design, when the upper guide unit is pre-positioned in the first position, it can be supported by the output end of the support cylinder 59 abutting against the upper limiting block 560. After the inner wall of the guide groove 541 contacts the docking block 84, the interaction between the inner wall of the guide groove 541 and the docking block 84 causes the upper guide unit to move slightly upward along the second guide rail 520. It should be noted that the distance between the upper and lower limiting blocks 560 allows the upper guide unit to move slightly upward along the second guide rail 520 without interfering with the support cylinder 59. When the upper guide unit is pre-positioned in the second position, it can be supported by the output end of the support cylinder 59 abutting against the lower limiting block 560. After the inner wall of the guide groove 541 contacts the docking block 84, the interaction between the inner wall of the guide groove 541 and the docking block 84 causes the upper guide unit to move slightly upward along the second guide rail 520.

[0095] Combination Figure 1 , Figure 16 , Figure 17 and Figure 18As shown, the demolding unit in this embodiment further includes a second mounting base 63 disposed on the second connecting base 60, a second linear driver 64 disposed on the second mounting base 63, and a second connecting frame 65 slidably disposed on the second mounting base 63. The second driving component 62 is fixedly disposed on the second connecting frame 65, and the second linear driver 64 is connected to the second connecting frame 65 and is used to drive the second connecting frame 65 to reciprocate along the axial direction of the transmission screw 61. Therefore, the second connecting frame 65 and the second driving component 62 disposed on the second connecting frame 65 can be moved by the second linear driver 64. Compared to the scheme where the demolding fixture 6 is moved as a whole by the robotic arm 7, which in turn moves the second driving component 62, the control precision of driving the second driving component 62 by the second linear driver 64 is higher. To ensure the sliding stability of the second connecting frame 65 and the second driving component 62, a third guide rail 630 is also provided between the second connecting base 60 and the second connecting frame 65 in this embodiment.

[0096] Similarly, in order to adapt to different specifications and models of basin insulators, the demolding unit in this embodiment is provided with two sets and the two sets of demolding units are arranged at intervals. The demolding fixture 6 also includes a second adjusting mechanism 66 provided on the second connecting seat 60. The second adjusting mechanism 66 is connected to the demolding unit and is used to adjust the distance between the two sets of demolding units by driving the two sets of demolding units to move relative to each other.

[0097] In this embodiment, the second adjusting mechanism 66 is a cylinder, and the cylinder body and output end are respectively connected to the second mounting base 63 in the two sets of demolding units. In this embodiment, a fourth guide rail 67 is also provided between the second connecting base 60 and the second mounting base 63 to ensure the sliding stability of the demolding unit during the position adjustment process.

[0098] The demolding fixture 6 in this embodiment also includes a positioning element, which is used to cooperate with the pin hole on the basin insulator to align the transmission screw 61 with the screw hole on the basin insulator. The positioning element in this embodiment includes a first positioning pin 68 and a second positioning pin 690, wherein the first positioning pin 68 is fixedly disposed on the second connecting seat 60, and the second positioning pin 690 is movably disposed relative to the second connecting seat 60. Specifically, the positioning element also includes a third linear actuator 69 disposed on the second connecting seat 60, and the second positioning pin 690 is disposed at the output end of the third linear actuator 69. That is, the third linear actuator 69 can drive the second positioning pin 690 to move relative to the second connecting seat 60. The first locating pin 68 and the second locating pin 690 are respectively adapted to the screw holes on different specifications and models of basin insulators. By setting a third linear actuator 69, the extension length of the second locating pin 690 relative to the first locating pin 68 can be controlled. In this way, when the first locating pin 68 needs to be mated with the screw hole, the second locating pin 690 is controlled to retract to avoid interference between the second locating pin 690 and the basin insulator; when the second locating pin 690 needs to be mated with the screw hole, the second locating pin 690 is controlled to extend to avoid interference between the first locating pin 68 and the basin insulator.

[0099] In summary, the automated demolding integrated device provided in this embodiment can automatically disassemble the locking screw 83 on the mold 8 through the cooperation of the nut locking fixture 3 and the screw disassembly work. The mold splitting fixture 5 can open the mold 8 into a left half mold 80 and a right half mold 81. The demolding fixture 6 can remove the basin insulator from the mold 8. This achieves fully automated demolding of the basin insulator relative to the mold 8, significantly improving work efficiency and eliminating safety risks.
