[0002] Pot insulators are formed by using molds. After casting, demoulding is required to take out the pot insulators. In the prior art, horizontal demoulding is adopted. After cleaning the mating surfaces of the molds, tools are used to pry open the upper mold and the lower mold, and a suspension tool is used to move the upper mold to a designated position, then the pot insulator is taken off, the upper mold and the lower mold are cleaned, and then the two are mated and connected for mold closing.

[0003] However, the following problems exist in the prior art: (1) During the cleaning, demoulding and subsequent mold closing processes, in order to remove or install each connecting part, the mold needs to be flipped multiple times, the operation is complex, the work efficiency is poor, and foreign matters are likely to be mixed into the subsequent mold closing, directly affecting the quality of the next pot insulator; (2) Affected by the casting process, after casting, foreign matters adhere to the inner and outer surfaces of the mold, and the foreign matters falling between the two molds have a great impact on the quality of the next pot insulator. Although there is cleaning work before mold opening and before mold closing, in practice, the poor quality caused by foreign matters has always been a key concern of enterprises; (3) The edge of the pot insulator is close to the edge of the mold, and the method of prying open the upper mold and the lower mold is likely to damage the product.

[0078] Unless otherwise defined, the technical terms or scientific terms used in this specification and claims shall have the ordinary meanings as understood by those of ordinary skill in the technical field to which the present invention belongs.

[0079] Reference Figures 1-4 Understand. An embodiment of the present invention provides a vertical semi-automatic demolding device for pot insulators (hereinafter referred to as the "demolding device") for demolding a vertically placed closed mold.

[0080] The demoulding device includes a workbench 1, a first tooling 2, a second tooling 3, an expansion separator 4, and a separator position adjustment module 5. Among them, the core operations of demoulding and mould closing are carried out on the workbench 1. The first tooling 2 is used to lock the first half-mould 8 placed vertically, and the second tooling 3 is used to lock the second half-mould 9 placed vertically; the thickness direction of the mould is in the same direction as the movement direction of the first tooling 2 (or the second tooling 3), and the first tooling 2 and / or the second tooling 3 are slidably connected to the workbench 1 in the horizontal direction, so that the first half-mould 8 and the second half-mould 9 move away from or close to each other, so as to reserve enough safe operation space for taking out the pot-type insulator, cleaning the inner surfaces of the two moulds, and the mould closing operation. Expansion separation plates 82 are arranged on the sides of the first half-mould 8 and the second half-mould 9. The expansion separation plates 82 are arranged in pairs, that is, each expansion separation plate 82 on the first half-mould 8 and each expansion separation plate 82 on the second half-mould 9 are arranged in one-to-one correspondence. The expansion separator 4 is used to apply a force to the two expansion separation plates 82 in the same pair, so that the first half-mould 8 and the second half-mould 9 in the mould-closed state are separated by a small distance. The expansion separator 4 is installed on the separator position adjustment module 5. The separator position adjustment module 5 is used to adjust the position of the expansion separator 4 relative to the workbench 1. During use, the expansion separator 4 is adjusted between the two expansion separation plates 82, and when not in use, the expansion separator 4 is adjusted to a safe area that does not affect manual operation.

[0081] Here, the application of the demoulding device is briefly described as a whole in combination with the above scheme. For detailed application information, see the following demoulding method. Adjust the relative positions of the first tooling 2 and the second tooling 3, place, position and lock the first half-mould 8 and the second half-mould 9 in the mould-closed state vertically on the first tooling 2 and the second tooling 3, manually remove the connecting parts of the first half-mould 8 and the second half-mould 9, use the separator position adjustment module 5 to position the expansion separator 4 on the side of the mould, and manually fine-tune to position the expansion separator 4 between the two oppositely arranged expansion separation plates 82. Control the synchronous movement of each expansion separator 4 to separate the first half-mould 8 and the second half-mould 9 by a certain distance. Correspondingly, the first tooling 2 and the second tooling 3 are also separated by the same distance. Withdraw the expansion separator 4, and then by adjusting the relative positions of the first tooling 2 and the second tooling 3, make the distance between the first half-mould 8 and the second half-mould 9 more than 1000 mm; after removing the pot-type insulator, clean the inner surfaces of the first half-mould 8 and the second half-mould 9, and then perform the mould closing operation on the two.

[0082] As can be seen from the above, first, the present invention performs mold closing and demolding operations in a vertical state. During this process, there is no need to flip the mold, eliminating the flipping operation, improving work efficiency. Moreover, the two molds are not in an up-and-down relationship, so there is no problem of foreign objects falling onto each other's inner surfaces, which improves the product qualification rate for mass production of the demolding device. Second, the present invention applies a force to the expansion and separation plate 82 outside the mold to separate the first half mold 8 and the second half mold 9 by a certain distance, without damaging the pot-shaped insulator itself, and has a higher qualification rate compared to the prior art. Third, the semi-automatic nature is reflected in that the operations of expanding and horizontally moving the mold are achieved through the demolding device, and the work of removing and installing the connecting members of the first half mold 8 and the second half mold 9 is achieved manually. Therefore, as long as the mold feet of different types of molds can be matched with the first tooling 2 and the second tooling 3, the demolding device provided by each embodiment of the present invention can be used to demold molds of various structures and sizes. In other words, the demolding device provided by the embodiments of the present invention has universality. Fourth, when demolding is performed using the demolding device provided by the embodiments of the present invention, only two people are required to operate, saving manpower compared to the prior art.

[0083] The overall structure of the demolding device has been described above and its application has been briefly explained. Next, the structures of the workbench 1, the first tooling 2, the second tooling 3, the expansion separator 4, and the separator position adjustment module 5 will be further introduced in detail.

[0084] In the embodiment of the present invention, the workbench 1 is fixedly arranged, used to provide an operating platform for demolding and also provide an installation basis for other components of the demolding device. The workbench 1 includes a support frame 11 and end plates 12. The support frame 11 adopts a frame structure, for example, made by crisscrossing and fixedly connecting several beams. The end plates 12 are arranged at the top of the support frame 11, and several holes and grooves can be arranged on the end plates 12 for connecting with other components or providing space for other components to avoid.

[0085] In the embodiment of the present invention, the first tooling 2 includes a first base 21 and a first pressing mechanism 22. The first base 21 has a first positioning structure for positioning the first half mold 8. The first positioning structure can be a hole located on the first base 21, or a positioning post 211 directly or indirectly arranged on the first base 21, or a positioning surface located on the first base 21. Figures 1-4In the illustrated embodiment, the first positioning structure adopts the positioning post 211 structure. Correspondingly, holes adapted to the positioning posts 211 are provided on the cornea of the first half mold 8. The output end of the first pressing mechanism 22 can move relative to the first base 21. After the first mold leg 81 of the first half mold 8 is placed on the first base 21, the first pressing mechanism 22 is used to apply a force towards the first base 21 to lock it on the first base 21. In the embodiment of the present invention, the first tooling 2 combines the positioning function and the pressing function, improving the demolding efficiency, the stability and reliability of the mold during the operation. At the same time, the positioning function and the pressing function are realized by different structures. Correspondingly, the structures corresponding to these two functions on the mold leg (the part for connecting with the first base 21) of the first half mold 8 are also separately arranged, which has higher reliability for the mold.

[0086] In the embodiment of the present invention, there are two first pressing mechanisms 22 on the first base 21 to obtain higher reliability. In other embodiments, the solutions of providing one first pressing mechanism 22 or three or more first pressing mechanisms 22 are also within the protection scope of the present invention.

[0087] In the embodiment of the present invention, the first pressing mechanism 22 includes a first pressing plate 221, a first connecting rod 222 and a first transmission member. The first transmission member includes a first transmission block 223 and a first lead screw. Two ends of the first connecting rod 222 are respectively rotatably connected to the first pressing plate 221 and the first base 21. One end of the first pressing plate 221 is rotatably connected to the first transmission block 223, and the other end of the first pressing plate 221 is used to press the first mold leg 81. The first mold leg 81 includes a square first positioning plate, and the first positioning plate is in contact with the first base 21. The first pressing plate 221 can directly press on the first positioning plate, or a first pressing portion protruding upward or protruding in the direction away from the first half mold 8 can be provided on the first positioning plate, and the first pressing plate 221 presses on the first pressing portion. The first transmission block 223 can be directly threadedly connected to the first lead screw, or can be fixedly connected to a nut, and the nut is threadedly connected to the first lead screw, that is, the first transmission block 223 is indirectly threadedly connected to the first lead screw. The vertically arranged first lead screw is rotatably connected to the first base 21 and is driven by a motor. When the motor rotates forward, the first transmission block 223 moves upward, the first pressing plate 221 rotates and presses the first mold leg 81. When the motor rotates reversely, the first transmission block 223 moves downward, and the first pressing plate 221 rotates in the reverse direction and disengages from the first mold leg 81. In some embodiments, the two first pressing mechanisms 22 on the first tooling 2 are synchronously controlled.

[0088] It should be noted that in some other embodiments, as an alternative means, the first transmission member can adopt a cylinder, a hydraulic cylinder or an electric cylinder.

[0089] In an embodiment of the present invention, the second tooling 3 includes a second base 31 and a second pressing mechanism 32. The second base 31 has a second positioning structure for positioning the second half mold 9. The second positioning structure can be a hole located on the second base 31, or a positioning post 211 directly or indirectly provided on the second base 31, or a positioning surface located on the second base 31; Figures 1-4 In the illustrated embodiment, the second positioning structure adopts the structure of the positioning post 211. Correspondingly, a hole adapted to the positioning post 211 is provided on the cornea of the second half mold 9. The output end of the second pressing mechanism 32 can move relative to the second base 31. After the second mold leg 91 of the second half mold 9 is placed on the second base 31, the second pressing mechanism 32 is used to apply a force towards the second base 31 to lock it on the second base 31. In this embodiment, the second tooling 3 combines the positioning function and the pressing function, improving the demolding efficiency, the stability and reliability of the mold during the operation. At the same time, the positioning function and the pressing function are realized by different structures. Correspondingly, the structures corresponding to these two functions on the mold leg (the part for connecting with the second base 31) of the second half mold 9 are also separately arranged, which has higher reliability for the mold.

[0090] In an embodiment of the present invention, there are two second pressing mechanisms 32 on the second base 31 to obtain higher reliability. In other embodiments, the solutions of setting one second pressing mechanism 32 or three or more second pressing mechanisms 32 are also within the protection scope of the present invention.

[0091] The second pressing mechanism 32 includes a second pressing plate 321, a second connecting rod 322 and a second transmission member. The second transmission member includes a second transmission block 323 and a second lead screw. The two ends of the second connecting rod 322 are respectively rotatably connected to the second pressing plate 321 and the second base 31. One end of the second pressing plate 321 is rotatably connected to the second transmission block 323, and the other end of the second pressing plate 321 is used to press the second mold leg 91. The second mold leg 91 includes a square second positioning plate, and the second positioning plate is in contact with the second base 31. The second pressing plate 321 can directly press on the second positioning plate, or a second pressing portion protruding upward or protruding in a direction away from the second half mold 9 can be provided on the second positioning plate, and the second pressing plate 321 presses on the second pressing portion. The second transmission block 323 is directly or indirectly threadedly connected to the second lead screw. The vertically arranged second lead screw is rotatably connected to the second base 31 and is driven by a motor; when the motor rotates forward, the second transmission block 323 moves upward, the second pressing plate 321 rotates and presses the second mold leg 91, and when the motor rotates in reverse, the second transmission block 323 moves downward, and the second pressing plate 321 rotates in the reverse direction and disengages from the second mold leg 91. In some embodiments, the two second pressing mechanisms 32 on the second tooling 3 are synchronously controlled.

[0092] It should be noted that in some other embodiments, as an alternative means, the second transmission member may be a cylinder, a hydraulic cylinder or an electric cylinder.

[0093] When the first tooling 2 and the second tooling 3 are slidably connected to the workbench 1, a traction force detection module is provided, which is used to output the traction force when the first tooling 2 or the second tooling 3 slides relative to the workbench. For example, when the linear transmission mechanism 6 drives the first tooling 2 to move, the motor driving the traction lead screw 61 to rotate has a power, and the traction force detection module can obtain the traction force according to this power. The traction force can be used to judge whether the half mold is stuck or whether the positive pressure is too large when the two half molds are clamped.

[0094] In the embodiment of the present invention, the vertical semi-automatic demolding device for pot-type insulators further includes a linear transmission mechanism 6. The output end of the first tooling 2 is detachably connected to the linear transmission mechanism 6, and the second tooling 3 is rotatably connected to the linear transmission mechanism 6. The second tooling 3 is arranged at a position close to one end of the workbench 1 (i.e., the second end of the workbench 1), and the first tooling 2 slides between the first end and the second tooling 3 of the workbench 1. In some other embodiments, as an alternative means, the first tooling 2 can be fixed, the second tooling 3 is slidably connected to the workbench 1, and the relative position of the half mold is controlled by driving the second tooling 3, or both the first tooling 2 and the second tooling 3 are slidably connected to the workbench 1, and the relative position of the half mold is controlled by driving the first tooling 2 and the second tooling 3 simultaneously.

[0095] The linear transmission mechanism 6 includes a mutually matching traction lead screw 61 and a traction nut. The two ends of the traction lead screw 61 are rotatably connected to the two ends of the workbench 1. Among them, in some embodiments, the traction lead screw 61 is a unidirectional lead screw, the first base 21 is fixedly connected to the traction nut, and the second base 31 is rotatably connected to the traction lead screw 61; in some other embodiments, the traction lead screw 61 is a bidirectional lead screw, the traction nut corresponding to the thread of one rotation direction of the bidirectional lead screw is connected to the first base 21, and the traction nut corresponding to the thread of the other rotation direction of the bidirectional lead screw is connected to the second base 31. Or, in some other embodiments, the linear transmission mechanism 6 adopts a cylinder, a hydraulic cylinder, an electric cylinder or other mechanisms capable of outputting linear motion, which are also within the protection scope of the present invention.

[0096] In the embodiment of the present invention, the vertical semi-automatic demolding device for pot-type insulators further includes a guiding mechanism 7. The guiding mechanism 7 is used to guide the moving direction of the first tooling 2 and / or the second tooling 3 so that it runs smoothly along a preset direction, and the preset direction is the same as the linear motion output by the linear transmission mechanism 6.

[0097] The arrangement of the guiding mechanism 7 and the linear transmission mechanism 6 is not restricted. In some embodiments, in the width direction of the workbench 1, the linear transmission mechanism 6 is arranged in the middle area between the first tooling 2 and the second tooling 3, and guiding mechanisms 7 are respectively arranged on both sides of the linear transmission mechanism 6 and close to the edges of the two toolings; in some other embodiments, as an alternative means, the guiding mechanism 7 can also be arranged in the middle area, and the linear transmission mechanism 6 can be arranged at both sides.

[0098] The guiding mechanism 7 includes a track 71 arranged in parallel with the traction lead screw 61 and a plurality of sliders 72. Regardless of how the guiding mechanism 7 and the linear transmission mechanism 6 are arranged, and regardless of how the motion relationship between the first tooling 2 and the second tooling 3 is set, both ends of the track 71 can be fixed to both ends of the workbench 1, and a part of the sliders 72 can be fixed to the first base 21, and another part of the sliders 72 can be fixed to the second base 31; it should be noted that in some embodiments, when the second tooling 3 is fixedly arranged relative to the workbench 1, sliders 72 can still be arranged on the second base 31. On the one hand, during the assembly process of the demoulding device, the relationship between the sliders 72 and the track 71 can be used to quickly and accurately position the second tooling 3. On the other hand, during the application of the demoulding device, the track 71 and the sliders 72 play a constraining role on the second tooling 3, improving the stability of the second tooling 3.

[0099] In the embodiments of the present invention, two expansion separators 4 are arranged on each side of the relative movement path of the first tooling 2 and the second tooling 3. Correspondingly, there are two groups of expansion separation plates 82 corresponding to both sides of the mold. When separating the mold, the four expansion separators 4 are controlled to move synchronously. The expansion separators 4 can be realized by cylinders, electric cylinders or a combination of both. Of course, hydraulic cylinder technology can also be used. In addition, the expansion separators 4 can be realized by using the existing technology, and the present invention will not elaborate further.

[0100] In the embodiments of the present invention, the separator position adjustment module 5 can move relative to the workbench 1. Preferably, it can move arbitrarily within the entire long side range of the workbench 1. The separator position adjustment module 5 includes two manipulators 51, a first driving mechanism 52 and a second driving mechanism 53. The two manipulators 51 are respectively arranged on both sides of the workbench 1. The two manipulators 51 can be slidably connected to the workbench 1 or slidably connected to the ground. The two manipulators 51 can be operated in a purely electric control manner, or can be jointly controlled by electric control and manual control. For example, after moving forward to any position in an electric control manner, it is not locked, and at this time, a certain reverse torque is manually applied, and the manipulator 51 can move backward to restore the original position.

[0101] The first driving mechanism 52 is used to synchronously adjust the relative position between the two manipulators 51 in the width direction of the workbench 1. Specifically, the separator position adjustment module 5 further includes a driving connection frame 54. In the width direction of the workbench 1, both ends of the driving connection frame 54 extend out respectively to form an extension part 541. The manipulator 51 is slidably connected to the extension part 541 on the same side. The two output ends of the first driving mechanism 52 are correspondingly connected to the manipulator 51 to drive the manipulator 51 to move. The first driving mechanism 52 can be realized by a driving member (such as a motor) cooperating with a mechanism having two output ends. The one driving member simultaneously drives the two output ends to move synchronously in opposite directions. It can also be realized by two driving members each cooperating with one output end. During operation, the two driving members are linked to ensure the synchronization of the two output ends.

[0102] The second driving mechanism 53 is used to synchronously adjust the position of the two manipulators 51 relative to the workbench 1 in the length direction of the workbench 1. Specifically, the second driving mechanism 53 can drive the above-mentioned driving connection frame 54 to drive the two manipulators 51 to move simultaneously. The second driving mechanism 53 can be realized by a driving member (such as a motor) driving a belt transmission mechanism, or can also be realized by a driving member driving a kinematic pair capable of outputting linear reciprocating motion. By adjusting the positions of the manipulator 51 in two directions, the position of the expanding separator 4 relative to the mold is adjusted. In the embodiment of the present invention, the angle, lateral position and vertical position of the expanding separator 4 can be further adjusted by setting the structure of the manipulator 51 itself. The specific scheme can be realized by the prior art, and the present invention does not limit the specific structure of the manipulator 51.

[0103] In the embodiment of the present invention, the demoulding device includes a control module. The control module includes a plurality of input buttons and a controller. Each button corresponds to a different function of the controller. Among them, the locking button corresponds to the function of locking and clamping the first tooling 2 and the second tooling 3. The unlocking button corresponds to the function of rotating and loosening the mold by the first pressing plate 221 and the second pressing plate 321. There are also corresponding buttons for the linear motion of the first tooling 2 and the second tooling 3 relative to the workbench 1.

[0104] An embodiment of the present invention further provides a semi-automatic demoulding system for a vertical pot insulator, which includes the above-mentioned demoulding device, and also includes a gantry and a hoisting device. Among them, the gantry is implemented by the prior art, and the demoulding device is located below the gantry; the hoisting device can run along the gantry, and this technology can be achieved by the prior art. The hoisting device includes hooks for suspending the first half mold 8, the second half mold 9, and the insulator flange. Correspondingly, lifting rings are provided on the first half mold 8, the second half mold 9, and the insulator flange. In the closed mold state, the hook is connected to the lifting ring on the first half mold 8 and / or the second half mold 9. When disassembling the pot insulator, the hook on the hook and the insulator flange are correspondingly connected. Among them, the insulator flange is pre-installed on the first half mold 8 through fasteners. After pouring, the pot insulator is connected through the insulator flange and the first half mold 8. After removing the insulator flange, the pot insulator is removed accordingly.

[0105] An embodiment of the present invention further provides a semi-automatic demoulding method for a vertical pot insulator, which is implemented by using the above-mentioned semi-automatic demoulding device for a vertical pot insulator. The demoulding method includes the following steps:

[0106] A. Transport the first half mold 8 and the second half mold 9 in the closed mold state and containing the pot insulator to the blanking area. Specifically, the blanking area is located at the first end of the demoulding device. A tray is set on the AGV trolley, and the mold stacked on the tray is hoisted to the blanking area through the hoisting device.

[0107] B. Make the first tooling 2 and the second tooling 3 in the demoulding working position and in the unlocked state. In this step, according to the sliding connection relationship between the first tooling 2 and the second tooling 3 and the workbench 1, it is adaptively selected whether to control the movement of the first tooling 2, or to control the movement of the second tooling 3, or to control the simultaneous movement of both to be realized in real time. This step can be verified when the position of the first tooling 2 and the second tooling 3 already meet the requirements of this demoulding after the previous mold is processed well; as an alternative means, this step can also be realized by operating the first tooling 2 and / or the second tooling 3 before positioning the mold for this demoulding.

[0108] C. Position and connect the first half - mold 8 and the second half - mold 9 with their surfaces cleaned and in the mold - closing state to the first tooling 2 and the second tooling 3. During specific implementation, lift the mold from the blanking area by a hoisting device, manually clean the surface of the mold, especially the bottom surface of the mold feet. Then hoist the mold directly above the first tooling 2 and the second tooling 3, and manually align the positioning holes on the mold feet below the mold with the positioning posts 211 on the first base 21 and the positioning posts 211 on the second base 31 for plug - in connection to achieve the positioning of the mold. Then press the corresponding button, and the first transmission member of the first pressing mechanism 22 and the second transmission member of the second pressing mechanism 32 act. The first pressing plate 221 rotates and presses the mold feet of the first half - mold 8 on the first base 21, and the second pressing plate 321 rotates and presses the mold feet of the second half - mold 9 on the second base 31, thereby locking the mold on the tooling.

[0109] D. After manually removing the connecting parts of the first half - mold 8 and the second half - mold 9, separate and expand the first half - mold 8 and the second half - mold 9 with the expansion separator 4, and then adjust the expansion separator 4 to one end of the workbench 1. Specifically, after removing the connecting parts, press the corresponding button, and the separator position adjustment module 5 acts. The second driving mechanism 53 drives the two manipulators 51 to move from the first end to both sides of the mold. Manually adjust the specific position of the expansion separator 4 to position it between the paired expansion separation plates 82. Press the corresponding button, and the four expansion separators 4 act synchronously to separate the first half - mold 8 and the second half - mold 9 by at least 10 mm. Generally, after separating by 10 mm, the positioning pins between the first half - mold and the second half - mold have been disengaged. Then manually or electrically control the two manipulators 51 to return to the first end to avoid interfering with the safety of subsequent operations. If it is detected that the manipulators 51 or the expansion separator 4 do not return to the first end, the system automatically stops the subsequent operations and gives an alarm, and then manual intervention is required to ensure that the manipulators 51 or the expansion separator 4 return to the first end.

[0110] E. Control the first tooling 2 and the second tooling 3 to move away from each other until the interval is at least 1000 mm. Taking the second tooling 3 not moving and the first tooling 2 moving as an example, press the corresponding button, and the motor drives the linear transmission mechanism 6 to act. The first tooling 2 moves to the first end. During this period, the traction force detection module calculates the traction force of the traction lead screw 61 in real - time according to the power of the motor. If the measured traction force exceeds the first threshold, it may be that the positioning pins of the first half - mold 8 and the second half - mold 9 are not completely disengaged or even stuck. At this time, the control module sends an alarm instruction and controls the motor to stop running. The linear transmission mechanism 6 and the first half - mold 8 stop accordingly. After manual intervention and verification to ensure there is no problem, press the corresponding button again to start the motor until the first tooling 2 runs to the specified position.

[0111] F. After the pot insulator is preliminarily positioned, remove it. Specifically, hook two lifting rings on the insulator flange with a lifting hook to preliminarily position the insulator flange. Remove the fasteners between the first half mold 8 and the insulator flange, and then use a lifting device in cooperation with manual labor to lift the insulator flange and the pot insulator connected to the insulator flange to the product storage area. Remove the pot insulator and stack it, and reserve the insulator flange after cleaning.

[0112] G. Clean the inner surface of the first half mold 8 and the inner surface of the second half mold 9, remove the attached impurities, and then apply a release agent to prepare for the production of the next pot insulator.

[0113] H. Control the first tooling 2 and the second tooling 3 to approach each other until they are aligned. Taking the second tooling 3 as stationary and the first tooling 2 as moving as an example, press the corresponding button, and the motor drives the linear transmission mechanism 6 to act. The first tooling 2 moves from the first end towards the second tooling 3. During this period, the traction force detection module calculates the traction force of the traction lead screw 61 in real time according to the power of the motor. If the measured traction force exceeds the second threshold, it may be that the positioning pins of the first half mold 8 and the second half mold 9 are not aligned and stuck, or the first half mold 8 and the second half mold 9 have been aligned and cannot move relatively further, otherwise it will damage the insulator flange or other structures inside the mold. At this time, the control module sends an alarm instruction and controls the motor to stop running. The linear transmission mechanism 6 and the first half mold 8 stop accordingly. After manual review and no problems, if the first half mold 8 and the second half mold 9 are not yet aligned, press the corresponding button again to start the motor until the first tooling 2 runs to the specified position. If the first half mold 8 and the second half mold 9 are already aligned, proceed to the next step.

[0114] I. Manually connect the first half mold 8 and the second half mold 9.

[0115] J. After disconnecting the connection between the first tooling 2 and the first half mold 8 and disconnecting the connection between the second tooling 3 and the second half mold 9, move the first half mold 8 and the second half mold 9 outside the vertical semi-automatic pot insulator demolding device. Specifically, press the corresponding button, and the first pressing mechanism 22 and the second pressing mechanism 32 act. The first pressing plate 221 and the second pressing plate 321 rotate and release the die feet. Connect the lifting hook to the half mold of the mold, and transport the mold to the specified area through the lifting device.
