Description

Technical Field

[0001] The present invention relates to the demolding technology of pot insulators, and particularly to a demolding method and a demolding system for pot insulators. Background Art

[0002] Pot insulators are formed by using molds. After casting, demolding is required to take out the pot insulators. In the prior art, horizontal demolding 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) In the processes of cleaning, demolding, and subsequent mold closing, 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 cleaning work is carried out before mold opening and before mold closing, the quality problems caused by foreign matters in practice have always been the key concerns 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.

[0089] 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 pertains.

[0090] The embodiments of the present invention provide a demolding method for a pot - type insulator, which is carried out in a vertical manner. The realization of the demolding method for the pot - type insulator can be achieved through the following demolding system. In the following description of the demolding method, it is described in combination with the demolding system, and when referring to the product, it is understood with reference to Figure 2-5 the demolding system involved.

[0091] As Figure 1 shown, the embodiments of the present invention provide a demolding method for a pot - type insulator, including the following steps:

[0092] S08. Transport the mold to be processed to the mold - closing and blanking area through an AGV cart carrying a tray;

[0093] S09. Lift the mold to be demolded from the mold - closing and blanking area for surface cleaning;

[0094] S10. Place the mold to be demolded vertically, and lock the first half mold and the second half mold of the mold respectively;

[0095] S20. Manually remove the connecting parts of the first half mold and the second half mold;

[0096] S30. Expand the first half mold and the second half mold by a first distance to completely separate the first half mold and the second half mold;

[0097] S40. Control the relative movement of the first half mold and the second half mold in the horizontal direction so that the distance between the first half mold and the second half mold is not less than 1000 mm;

[0098] S50. Remove the insulator flange and the pot insulator on the first half mold;

[0099] S60. Control the relative movement of the first half mold and the second half mold in the horizontal direction until they are aligned;

[0100] S70. Manually connect the first half mold and the second half mold and place them in the demolding and blanking area.

[0101] As can be seen from the above, this method performs the mold closing and demolding operations in a vertical state. During this period, there is no need to flip the mold, which saves the flipping operation and improves 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 the mass production of the demolding device.

[0102] Next, the demolding method will be specifically described in combination with the demolding system.

[0103] Step S10 is specifically implemented through the following steps:

[0104] S101. Put the positioning tooling in the unlocked state to facilitate placing the mold to be demolded;

[0105] S102. Hoist the mold in a vertical state directly above the positioning tooling;

[0106] S103. Position the lower end of the first half mold with the first tooling of the positioning tooling, and position the lower end of the second half mold with the second tooling of the positioning tooling;

[0107] S104. Control the first tooling and the second tooling to act synchronously. The first tooling locks the first half mold, and the second tooling locks the second half mold.

[0108] Step S30 specifically includes the following steps:

[0109] S301. Initially position the expansion separator on both sides of the mold;

[0110] S302, manually positioning the expansion separator between the expansion separation plates arranged in pairs on the sides of the first half mold and the second half mold; two pairs of expansion separation plates are arranged on each side of the mold, and each pair of expansion separation plates corresponds to one expansion separator;

[0111] S303, controlling the expansion separators to move synchronously to expand the first half mold and the second half mold, with the first distance being no less than 10 mm;

[0112] S304, controlling the expansion separator to move away from the mold.

[0113] Step S40 specifically includes the following steps:

[0114] S401, detect whether the expansion separator is near the mold. If so, an alarm is triggered, and the position of the expansion separator is manually adjusted before continuing with this step. If not, execute step S402. It should be noted that when specifically executing "detect whether the expansion separator is near the mold", it can be achieved by detecting whether the expansion separator is within a preset area, such as detecting whether the expansion separator is at the first end of the demolding device.

[0115] S402, loading traction force on the first tooling and / or the second tooling, and stopping loading traction force after the first half mold and the second half mold are separated by a second distance, during which the traction force is detected in real time. If the traction force exceeds a first threshold, stopping loading traction force and alarming, and continuing to execute this step after manual intervention to handle the alarm information, if not, continuing to execute this operation; wherein, the second distance is not less than 1000 mm.

[0116] Step S50 specifically includes the following steps:

[0117] S501. Use a lifting device to hook the lifting ring on the insulator flange and preliminarily fix the insulator flange;

[0118] S502, after removing the connecting piece between the insulator flange and the first half mold, the insulator flange and the pot-type insulator connected to the insulator flange are separated from the first half mold;

[0119] S503. Place the insulator flange and pot-type insulator products in the storage area through the lifting device, and remove the pot-type insulator for stacking.

[0120] Between step S50 and step S60, step S51 is also included:

[0121] The inner surface of the first mold half and the inner surface of the second mold half are cleaned and coated with a release agent.

[0122] Step S60 specifically includes the following steps:

[0123] S601. Apply traction force to the first tooling and / or the second tooling. Stop applying the traction force after the first half mold and the second half mold are aligned. During this period, the traction force is detected in real time. If the traction force exceeds the second threshold, stop applying the traction force and give an alarm. After the alarm information is processed manually, continue to execute this step. If not, continue to execute this operation.

[0124] The above generally describes the demoulding method. Next, in combination with Figure 1-5 A specific embodiment is given for detailed description. In the following introduction, the demoulding method includes the following steps:

[0125] A. Transport the first half mold 8 and the second half mold 9 with a pot insulator inside in the closed mold state to the closed mold blanking area. Specifically, the closed mold 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 lifted by a lifting device to the closed mold blanking area.

[0126] B. Place 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, adaptively select whether to control the movement of the first tooling 2, or control the movement of the second tooling 3, or control the movement of both at the same time to achieve in real time. This step can be carried out after the previous mold is processed and the first tooling 2 and the second tooling 3 already meet the requirements for this demoulding, and only need to check the position during this demoulding; 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.

[0127] C. Use the lifting device to lift the mold to be demoulded and clean its surface. Position and connect the first half mold 8 and the second half mold 9 in the closed mold state with clean surfaces to the first tooling 2 and the second tooling 3. Specifically, when executing, lift the mold vertically from the closed mold blanking area by the lifting device, manually clean the surface of the mold, especially the bottom surface of the mold feet should be cleaned thoroughly, and then lift the vertically placed mold to directly above the first tooling 2 and the second tooling 3. Cooperate with the operator to make the positioning holes on the mold feet below the mold correspond and plug into the positioning posts 211 on the first base 21 and the positioning posts 211 on the second base 31 to realize 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.

[0128] D. After manually removing the connecting parts of the first half-mold 8 and the second half-mold 9, the first half-mold 8 and the second half-mold 9 are separated and expanded by the expansion separator 4, and then the expansion separator 4 is adjusted 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 8 and the second half-mold 9 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.

[0129] 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 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. Manual intervention is required for rechecking. After ensuring that there is no problem, press the corresponding button again to start the motor until the first tooling 2 runs to the specified position.

[0130] F. After initially positioning the pot-type insulator, remove it; specifically, hook the two lifting rings on the insulator flange with a hook to initially position the insulator flange. Remove the fasteners between the first half-mold 8 and the insulator flange, and then use the lifting device in cooperation with manual labor to lift the insulator flange and the pot-type insulator connected to the insulator flange to the product storage area. Remove the pot-type insulator for stacking, and clean the insulator flange for standby.

[0131] G. Clean the inner surfaces of the first half-mold 8 and the second half-mold 9, remove the attached impurities, and then apply a release agent to prepare for the production of the next pot-type insulator.

[0132] 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 jammed, or the first half mold 8 and the second half mold 9 have been aligned and cannot move relative to each other further. Otherwise, it will damage the insulator flange or other structures inside the mold. Continuing to apply traction force will damage components such as the mold and the insulator flange. 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 will 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 designated position. If the first half mold 8 and the second half mold 9 are already aligned, proceed to the next step.

[0133] I. Manually connect the first half mold 8 and the second half mold 9.

[0134] 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 demoulding 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 convey the mold to the designated area through the hoisting device.

[0135] The embodiment of the present invention also provides a pot - type insulator demoulding system for implementing the above - mentioned pot - type insulator demoulding method; the pot - type insulator demoulding system includes a transportation device, a demoulding device, a gantry, and a hoisting device.

[0136] The transport device is used to transport the mold to be demolded to the mold-closing and blanking area at the first end of the demolding device, and is used to transport the demolded mold away from the demolding and blanking area at the second end of the demolding device; the transport device includes an AGV cart and a tray, and the tray is detachably installed on the top of the AGV cart, and the tray is used to support the mold. The gantry is implemented by the prior art, and the demolding device is located below the gantry; the hoisting device is matched with the gantry, and the hoisting device is used to hoist the mold, the insulator flange and the pot-type insulator. The hoisting device includes a hook for suspending the first half mold 8, the second half mold 9 and the insulator flange. Accordingly, hoisting rings are provided on the first half mold 8, the second half mold 9 and the insulator flange. In the mold-closing state, the hook is connected to the hoisting ring on the first half mold 8 and / or the second half mold 9. When disassembling the pot-type 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 casting, the pot-type insulator is connected to the first half mold 8 through the insulator flange. After removing the insulator flange, the pot-type insulator is removed accordingly. The demolding device is used to lock the first half mold and the second half mold, expand the first half mold and the second half mold, and control the relative movement of the first half mold and the second half mold.

[0137] Reference Figure 2-5 Understand. The demolding 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 demolding and mold closing are carried out on the workbench 1. The first tooling 2 is used to lock the vertically placed first half mold 8, and the second tooling 3 is used to lock the vertically placed second half mold 9; the thickness direction of the mold 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 mold 8 and the second half mold 9 are separated 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 molds and mold closing operations. Expansion separation plates 82 are provided on the sides of the first half mold 8 and the second half mold 9. The expansion separation plates 82 are arranged in pairs, that is, each expansion separation plate 82 on the first half mold 8 corresponds to each expansion separation plate 82 on the second half mold 9. 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 mold 8 and the second half mold 9 in the mold-closing state are separated by a small distance. The expansion separator 4 is installed on the separator position adjustment module 5, and the separator position adjustment module 5 is used to adjust the position of the expansion separator 4 relative to the workbench 1. When in 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.

[0138] Here, the application of the demoulding device is briefly described as a whole in combination with the above solutions. For detailed application information, refer to the above demoulding method. Adjust the relative positions of the first tooling 2 and the second tooling 3, vertically place, position and lock the first half-mould 8 and the second half-mould 9 in the closed-mould state 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 expanding separator 4 on the side of the mould, and manually fine-tune to position the expanding separator 4 between two oppositely arranged expanding separation plates 82. Control the synchronous movement of each expanding 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 expanding 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.

[0139] As can be seen from the above, first, the present invention performs the mould closing and demoulding operations in a vertical state. During this process, there is no need to flip the mould, eliminating the flipping operation, improving work efficiency, and since the two moulds are not in an up-and-down relationship, there is no problem of foreign objects falling onto each other's inner surfaces, thus improving the product qualification rate for the mass production of the demoulding device. Second, the present invention applies a force to the expanding separation plates 82 on the outside of the mould to separate the first half-mould 8 and the second half-mould 9 by a certain distance, without damaging the pot-type insulator itself, and has a higher qualification rate compared to the prior art. Third, one aspect of semi-automatic is that the operations of expanding and horizontally moving the mould are realized by the demoulding device, and the work of removing and installing the connecting parts of the first half-mould 8 and the second half-mould 9 is realized manually. Therefore, as long as the mould feet of different types of moulds can match the first tooling 2 and the second tooling 3, the demoulding device provided by each embodiment of the present invention can be used to demould moulds of various structures and sizes. In other words, the demoulding device provided by the embodiments of the present invention has universality. Fourth, when demoulding by using the demoulding device provided by the embodiments of the present invention, only two people are required to operate, saving manpower compared to the prior art.

[0140] The above has elaborated on the overall structure of the demoulding device and briefly described its application. Next, the structures of the workbench 1, the first tooling 2, the second tooling 3, the expanding separator 4, and the separator position adjustment module 5 will be further introduced in detail.

[0141] In the embodiment of the present invention, the workbench 1 is fixedly arranged, which is used to provide an operating platform for demoulding and also provides an installation basis for other components of the demoulding device. The workbench 1 includes a support frame 11 and end plates 12. The support frame 11 adopts a frame structure, for example, it is made by crisscrossing and fixedly connecting a number of beams. The end plates 12 are arranged at the top of the support frame 11. A number of holes and grooves can be arranged on the end plates 12 for connecting with other components or providing space for other components to avoid.

[0142] 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-mould 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. Figure 2-5 In the shown embodiment, the first positioning structure adopts the structure of the positioning post 211. Correspondingly, a hole adapted to the positioning post 211 is arranged on the cornea of the first half-mould 8. The output end of the first pressing mechanism 22 can move relative to the first base 21. After the first mould leg 81 of the first half-mould 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 demoulding efficiency, the stability and reliability of the mould during the operation process. 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 mould leg (the part for connecting with the first base 21) of the first half-mould 8 are also separately arranged, which has higher reliability for the mould.

[0143] 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 scheme of setting one first pressing mechanism 22 or three or more first pressing mechanisms 22 is also within the protection scope of the present invention.

[0144] In an 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 for pressing the first die foot 81. The first die foot 81 includes a square first positioning plate. The first positioning plate is attached to the first base 21. The first pressing plate 221 can directly press on the first positioning plate. A first pressing portion protruding upward or protruding in a direction away from the first half die 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 die foot 81. When the motor rotates in reverse, the first transmission block 223 moves downward, and the first pressing plate 221 rotates in the reverse direction and disengages from the first die foot 81. In some embodiments, the two first pressing mechanisms 22 on the first tooling 2 are synchronously controlled.

[0145] It should be noted that in some other embodiments, as an alternative means, the first transmission member can be a cylinder, a hydraulic cylinder, or an electric cylinder.

[0146] 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 die 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. Figure 2-5 In the shown 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 die 9. The output end of the second pressing mechanism 32 can move relative to the second base 31. After the second die foot 91 of the second half die 9 is placed on the second base 31, the second pressing mechanism 32 is used to apply a force toward 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 die foot (the part for connecting to the second base 31) of the second half die 9 are also separately arranged, which has higher reliability for the mold.

[0147] 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 providing one second pressing mechanism 32 or three or more second pressing mechanisms 32 are also within the protection scope of the present invention.

[0148] 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. 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 die foot 91. The second die foot 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 the direction away from the second half die 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 die foot 91. 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 die foot 91. In some embodiments, the two second pressing mechanisms 32 on the second tooling 3 are synchronously controlled.

[0149] It should be noted that in some other embodiments, as an alternative means, the second transmission member can adopt a cylinder, a hydraulic cylinder or an electric cylinder.

[0150] When the first tooling 2 and the second tooling 3 are slidably connected to the workbench 1, a traction force detection module is provided. The traction force detection module 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 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 die is stuck or whether the positive pressure is too large when the two half dies are clamped.

[0151] In the embodiment of the present invention, the demolding device 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 mold is controlled by driving the second tooling, 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.

[0152] The linear transmission mechanism 6 includes a traction lead screw 61 and a traction nut that match each other. 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 is also within the protection scope of the present invention.

[0153] In the embodiment of the present invention, the demolding device 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.

[0154] The arrangement of the guiding mechanism 7 and the linear transmission mechanism 6 is not limited. 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 mechanisms 6 are arranged on both sides.

[0155] 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 are fixed to the first base 21, and the other part of the sliders 72 are 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.

[0156] In the embodiment of the present invention, two expansion separators 4 are arranged on each side of the path of the relative movement 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 a cylinder, an electric cylinder or a combination of the two. Of course, it can also be realized by using hydraulic cylinder technology. In addition, the expansion separators 4 can be realized by using the existing technology, and the present invention will not elaborate.

[0157] In the embodiment 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 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.

[0158] The first driving mechanism 52 is used to synchronously adjust the relative positions of 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, an extension part 541 is formed at each end of the driving connection frame 54 by extending outwards. The manipulator 51 is slidably connected to the extension parts 541 on the same side. The two output ends of the first driving mechanism 52 are correspondingly connected to the manipulator 51 respectively 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 synchronous movement of the two output ends.

[0159] The second driving mechanism 53 is used to synchronously adjust the positions 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 driving a belt transmission mechanism, or can also be realized by a driving member driving other kinematic pairs capable of outputting linear reciprocating motion. By adjusting the positions of the manipulator 51 in two directions, the position of the expansion separator 4 relative to the mold is adjusted. In the embodiment of the present invention, the angle, lateral position and vertical position of the expansion 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.

[0160] In the embodiment of the present invention, the demolding 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 movement of the first tooling 2 and the second tooling 3 relative to the workbench 1.

Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
