Figure 10 The waterproof plug 20 on the demolding template 17 needs to be demolded into the mold hole 18 shown.

[0003] In existing technologies, the most primitive demolding method is still sometimes used, which is to manually remove each waterproof plug 20 one by one with hand clamps. However, since some waterproof plugs 20 are small in size, manual demolding is not convenient, has low demolding efficiency, and is labor-intensive for workers. Therefore, there are still shortcomings and deficiencies in existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide an automatic demolding machine for waterproof hydrants, so as to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: An automatic demolding machine for waterproof hydrants includes a frame with a horizontally mounted housing. Vertically distributed partitions divide the housing into an electrical control box and a demolding box. A controller is installed in the electrical control box. The demolding box has openings on both its top and bottom sides and a horizontally mounted displacement mechanism. A vertically distributed telescopic mechanism is mounted on the displacement mechanism, with its top end serving as a telescopic end. Two clamping plates that automatically move closer or further apart horizontally are mounted on the telescopic end. The controller is electrically connected to both the displacement mechanism and the telescopic mechanism. The top opening of the demolding box is also equipped with two horizontally opposite and spaced positioning rods. Each positioning rod has a material support plate installed on its opposite side, which is parallel to the positioning rod and is higher than the clamping plate.

[0006] Furthermore, the telescopic mechanism is a telescopic cylinder, and a pneumatic chuck with two jaws is coaxially mounted on the telescopic end of the telescopic cylinder. The pneumatic chuck is electrically connected to the controller, and the clamping plates are respectively mounted on the two jaws of the pneumatic chuck.

[0007] Furthermore, the displacement mechanism includes two horizontally opposite guide rods, each of which is connected to the demolding box. One of the guide rods is equipped with a lead screw that is parallel to the guide rod. Both ends of the lead screw are rotatably connected to the demolding box, and one end of the lead screw is also connected to a forward and reverse motor mounted on the chassis and electrically connected to the controller. A movable seat is fitted on the lead screw, and the side of the movable seat away from the lead screw is slidably fitted onto the two guide rods. The telescopic mechanism is installed on the movable seat.

[0008] Furthermore, each of the demolding boxes located at both ends of each positioning rod has a strip-shaped groove on its top surface. The strip-shaped groove is perpendicular to the positioning rod in the horizontal direction, and a nut that matches the strip-shaped groove is slidably connected in each strip-shaped groove. A cover plate is also fixedly connected to the opening of each strip-shaped groove. A strip-shaped slide is vertically opened on each cover plate and is parallel to the cover plate. Both ends of the positioning rod are threaded with a first connecting bolt. The screw end of the first connecting bolt passes through the positioning rod and the strip-shaped slide in sequence and is threadedly connected to the nut respectively.

[0009] Furthermore, a positioning sensing mechanism is also installed on the top surface of the demolding box. The positioning sensing mechanism is located between one end of the two positioning rods. The positioning sensing mechanism includes a horizontally arranged mounting plate connected to the top surface of the demolding box. One side of the mounting plate extends to the top of the opening of the demolding box and is equipped with a positioning sensor. The positioning sensor is electrically connected to the controller.

[0010] Furthermore, the mounting plate has a vertically formed strip-shaped through hole parallel to the positioning rod, and the mounting plate is connected to the top surface of the demolding box by a second connecting bolt. The screw end of the second connecting bolt passes through the strip-shaped through hole and is threadedly connected to the demolding box, and the head of the second connecting bolt abuts against the mounting plate.

[0011] Furthermore, the frame includes four vertically opposite retractable legs, and the chassis is mounted between the top ends of the four retractable legs.

[0012] Furthermore, each of the retractable outriggers includes a vertically distributed branch pipe. Each branch pipe has several equidistantly distributed first adjustment through holes from top to bottom. Each branch pipe is slidably connected to a movable rod. The top of each movable rod is connected to the chassis, and the bottom of each movable rod has a second adjustment through hole corresponding to the position of the first adjustment through hole. The second adjustment through hole and one of the first adjustment through holes are connected by a detachable connector.

[0013] Furthermore, the bottom opening of the demolding box is connected to a vertically distributed feeding hopper, which is a frustum-shaped structure that is wider at the top and narrower at the bottom.

[0014] Furthermore, a touch screen control panel that is electrically connected to the controller is embedded on the top surface of the electrical control box, and an openable transparent protective plate is installed on the touch screen control panel.

[0015] The beneficial effects of this utility model by adopting the above technical solution are as follows: In use, this invention allows the demolding template to be placed horizontally at a suitable position on two support plates, with the end of the waterproof plug facing downwards. Two positioning rods then fix the position of the demolding template. A displacement mechanism and a telescopic mechanism then move the two clamping plates horizontally and vertically. Since the two clamping plates can move closer or further apart horizontally, multiple rows of waterproof plugs on the demolding template can be automatically demolded sequentially. In summary, this invention facilitates the automatic demolding of waterproof plugs on the demolding template, thereby improving demolding efficiency and reducing the labor intensity of workers.

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 9 As shown, this utility model provides an automatic demolding machine for waterproof hydrants, used in applications such as... Figure 10 On the demolding template 17 shown, multiple waterproof plugs 20 arranged in a rectangular array are automatically demolded; specifically, handles 18 are installed on both sides of the demolding template 17 for easy hand movement; and multiple mold holes 19 arranged in a rectangular array are opened on the demolding template 17 for inserting the finished waterproof plugs 20; in addition, Figure 8 For example, the direction in which the stripping template 17 is parallel to the positioning rod 10 is the length direction of the stripping template 17.

[0020] This utility model includes a frame 8, on which a horizontally arranged housing 4 is mounted. Vertically distributed partitions 43 are installed inside the housing 4, dividing the housing 4 into an electrical control box 41 and a demolding box 42. The electrical control box 41 is equipped with a controller, which is a PLC controller in the prior art. The demolding box 42 has openings on both the top and bottom. The bottom opening of the demolding box 42 is the material discharge port. In use, a material bucket can be placed below the bottom opening of the demolding box 42 to hold the waterproof plug 20 that discharges material from the demolding box 42.

[0021] Furthermore, a horizontally arranged displacement mechanism 5 is installed inside the demolding box 42. A telescopic mechanism 2, capable of reciprocating along the displacement mechanism 5 and vertically distributed, is mounted on the displacement mechanism 5. Figure 8For example, driven by the displacement mechanism 5, the telescopic mechanism 2 can move along the length of the demolding template 17; the top of the telescopic mechanism 2 is the telescopic end, and the telescopic end of the telescopic mechanism 2 is equipped with two clamping plates 1 that can automatically move closer or further apart in the horizontal direction. The controller is electrically connected to the displacement mechanism 5 and the telescopic mechanism 2 respectively; specifically, the telescopic mechanism 2 can drive the two clamping plates 1 to move in the vertical direction; and driven by the displacement mechanism 5, with Figure 8 For example, it can indirectly drive the two clamping plates 1 to move along the length direction of the demolding template 17; in addition, the clamping plates 1 are all horizontally set and parallel to the width direction of the demolding template 17, and the length of the clamping plates 1 is sufficient to clamp the entire row of waterproof plugs 20 on the demolding template 17 at the same time. In this way, multiple waterproof plugs 20 in a row can be demolded at the same time during use, so that multiple rows of waterproof plugs 20 on the demolding template 17 can be automatically demolded in sequence.

[0022] Two horizontally positioned and spaced-apart positioning rods 10 are installed at the top opening of the demolding box 42. Each positioning rod 10 has a material support plate 11 parallel to it on its opposite side. The material support plate 11 is higher than the clamping plate 1. Specifically, ... Figure 8 For example, the distance between the two positioning rods 10 is adapted to the width of the demolding template 17, that is, the distance between the two positioning rods 10 is slightly greater than the width of the demolding template 17. When in use, by holding the demolding template 17, the demolding template 17 can be placed horizontally on the two material support plates 11 at a suitable position, and the end of the waterproof plug 20 outside the demolding template 17 is facing down. At this time, the position of the demolding template 17 can be fixed by the two positioning rods 10. Then, the displacement mechanism 5 and the telescopic mechanism 2 can drive the two clamping plates 1 to move in the horizontal and vertical directions. Since the two clamping plates 1 can move closer or further away from each other in the horizontal direction, the multiple rows of waterproof plugs 20 on the demolding template 17 can be automatically demolded in sequence.

[0023] Specifically, before use, the equipment is powered on and reset. In the initial state, the telescopic mechanism 2 is retracted, and there is a certain gap between the two clamping plates 1. During use, after the release template 17 is placed, the extension of the telescopic mechanism 2 raises the two clamping plates 1 until they are positioned on either side of the row of waterproof tassels 20. At this point, there is a vertical gap between the clamping plates 1 and the release template 17, preventing them from lifting the release template 17. Then, the two clamping plates 1 move closer together to clamp the waterproof tassels 20, and the telescopic mechanism 2 retracts. The two clamping plates 1 are lowered to clamp the waterproof plugs 20 for demolding. Then, the two clamping plates 1 move away from each other. At this time, the waterproof plugs 20 can fall into the demolding box 42 for unloading. Then, driven by the displacement mechanism 5, the two clamping plates 1 can be moved to the position of the next row of waterproof plugs 20 on the demolding template 17 for demolding. In this way, multiple rows of waterproof plugs 20 on the demolding template 17 can be automatically demolded in sequence. After all the waterproof plugs 20 are demolded, a new demolding template 17 is replaced. At the same time, driven by the displacement mechanism 5, the clamping plates 1 can be moved back to the initial position.

[0024] In summary, this utility model facilitates the automatic demolding of the waterproof plug 20 on the demolding template 17, thereby improving the demolding efficiency of the waterproof plug 20 and reducing the labor intensity of workers.

[0025] The specific arrangement of the telescopic mechanism 2 and the specific arrangement of the two clamping plates 1 that can automatically move closer or further apart in the horizontal direction are as follows: Figures 1 to 4 As shown, the telescopic mechanism 2 is a telescopic cylinder. A pneumatic chuck 3 with two jaws 31 is coaxially mounted on the telescopic end of the telescopic cylinder. The pneumatic chuck 3 is electrically connected to the controller, and the clamping plates 1 are respectively mounted on the two jaws 31 of the pneumatic chuck 3. Specifically, both the telescopic cylinder and the pneumatic chuck 3 are externally connected to solenoid valves that are electrically connected to the controller, and can be connected to the same set of air sources. In use, by moving the two jaws 31 on the pneumatic chuck 3 closer to or further away from each other in the horizontal direction, the two clamping plates 1 can be automatically moved closer to or further away from each other in the horizontal direction. Under the drive of the telescopic cylinder, the two clamping plates 1 can be indirectly moved and raised in the vertical direction through the pneumatic chuck 3.

[0026] The specific configuration of displacement mechanism 5 is as follows: Figure 3 and Figure 4 As shown, the displacement mechanism 5 includes two horizontally opposite guide rods 51, each guide rod 51 being connected to the demolding box 42. Specifically, ... Figure 8For example, the guide rod 51 is parallel to the length direction of the demolding template 17, and each guide rod 51 has a first support 54 fixedly fitted at both ends. The first supports 54 are all installed on the inner bottom surface of the demolding box 42. Furthermore, a lead screw 52 is provided outside one of the guide rods 51, parallel to the guide rod 51. Both ends of the lead screw 52 are rotatably connected to the demolding box 42. Specifically, both ends of the lead screw 52 are rotatably connected to a second support 55, which is installed on the inner bottom surface of the demolding box 42. One end of the lead screw 52 is also connected to a forward and reverse motor installed on the housing 4 and electrically connected to the controller. The forward and reverse motor is a stepper motor, not shown in the figure. A movable seat 53 is mounted on the lead screw 52. The side of the movable seat 53 away from the lead screw 52 is slidably mounted on two guide rods 51. The telescopic mechanism 2 is installed on the movable seat 53. Specifically, when the forward and reverse motor is started, it can drive the lead screw 52 to rotate. During the rotation of the lead screw 52, ​​it can drive the movable seat 53 to move along the guide rods 51. The telescopic mechanism 2 can move synchronously with the movable seat 53. In this way, through the telescopic mechanism 2, the two clamping plates 1 can be indirectly driven to move back and forth along the length direction of the stripping template 17.

[0027] Furthermore, such as Figures 1 to 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, strip-shaped grooves are formed on the top surface of the demolding box 42 located at both ends of each positioning rod 10. The strip-shaped grooves are perpendicular to the positioning rod 10 in the horizontal direction, and a nut 12 that matches the strip-shaped groove is slidably connected in each strip-shaped groove. That is, the nut 12 can slide along the strip-shaped groove, but cannot rotate in the strip-shaped groove. A cover plate 44 is also fixedly connected to the groove opening of each strip-shaped groove. A strip-shaped slide 45 is vertically formed on the cover plate 44 and is parallel to the cover plate 44. The width of the strip-shaped slide 45 is smaller than the groove width of the strip-shaped groove. The two ends of the positioning rod 10 are threadedly connected to the first connecting bolt 13. The screw end of the first connecting bolt 13 passes through the fixed bolt in sequence. Positioning rod 10 and strip slide 45 are respectively threaded to nut 12. Specifically, in use, by rotating the first connecting bolt 13 until the head of the first connecting bolt 13 is pressed against the positioning rod 10, the position of the positioning rod 10 can be fixed on the top surface of the demolding box 42. By rotating the first connecting bolt 13 in the opposite direction, after the head of the first connecting bolt 13 is moved away from the positioning rod 10, the positioning rod 10 can slide along the strip slide 45. In this way, in use, it is convenient to adjust the distance between the two positioning rods 10 according to the size specifications of the demolding template 17. After adjustment, the position of the positioning rod 10 can be fixed again using the first connecting bolt 13 for easy use.

[0028] Furthermore, such as Figures 1 to 3 , Figure 8 and Figure 9 As shown, a positioning sensing mechanism 6 is also installed on the top surface of the demolding box 42. The positioning sensing mechanism 6 is located between one end of the two positioning rods 10. The positioning sensing mechanism 6 includes a horizontally arranged mounting plate 61 connected to the top surface of the demolding box 42. One side of the mounting plate 61 extends above the opening on the top surface of the demolding box 42 and a positioning sensor 62 is installed thereon. The positioning sensor 62 is electrically connected to the controller. Specifically, two positioning sensors 62 can be set, and the two positioning sensors 62 are arranged opposite each other and both are electrically connected to the controller. In use, it can be used as follows: Figure 8 As shown, one of the handles 19 on the stripping template 17 is abutted against the two positioning sensors 62 respectively. With the position of the positioning sensing mechanism 6 as a reference, the stripping template 17 can be easily placed horizontally in a suitable position on the two material support plates 11; and it can also be used to detect whether the stripping template 17 is placed in the correct position.

[0029] In addition, a start button 15 and an emergency stop switch 16, which are electrically connected to the controller, are also installed on the top surface of the electrical control box 41. Specifically, during use, when the positioning sensing mechanism 6 detects that the demolding template 17 has been placed in place, pressing the start button 15 will automatically control the various components electrically connected to the controller to run in sequence. In addition, if the positioning sensing mechanism 6 does not detect the demolding template 17, the equipment will not run even if the start button 15 is pressed, so as to avoid equipment failure due to misoperation. When any emergency occurs in the automatic demolding machine of this utility model, pressing the emergency stop switch 16 can immediately stop the operation of the equipment.

[0030] Furthermore, such as Figures 1 to 3 , Figure 8 and Figure 9 As shown, the mounting plate 61 has a vertically arranged strip-shaped through hole 63 parallel to the positioning rod 10. The mounting plate 61 is connected to the top surface of the demolding box 42 by a second connecting bolt 64. The screw end of the second connecting bolt 64 passes through the strip-shaped through hole 63 and is threaded to the demolding box 42. The head of the second connecting bolt 64 abuts against the mounting plate 61. This facilitates the installation and removal of the positioning sensing mechanism 6 on the top surface of the demolding box 42. Secondly, when the second connecting bolt 64 is loosened, the position of the mounting plate 61 can be adjusted along the strip-shaped through hole 63. This facilitates the adjustment of the positioning sensor 62 to a suitable position according to the size and specifications of the demolding template 17. In addition, two strip-shaped through holes 63 can be opened and arranged opposite each other, and multiple second connecting bolts 64 can be set. The screw end of each second connecting bolt 64 passes through the strip-shaped through hole 63 and is threaded to the demolding box 42. This prevents the mounting plate 61 from tilting when adjusting its position.

[0031] The specific setup method for rack 8 is as follows: Figure 1 , Figure 3 and Figure 8 As shown, the frame 8 includes four vertically distributed telescopic legs, and the housing 4 is mounted between the tops of the four telescopic legs. Specifically, by setting the telescopic legs, the height of the housing 4 can be adjusted to a suitable position according to the height of the operator during use.

[0032] The specific configuration of the retractable outriggers is as follows: Figure 1 , Figure 3 and Figure 8 As shown, each telescopic outrigger includes a vertically distributed branch pipe 81. Several equidistant first adjustment through holes 82 are formed on each branch pipe 81 from top to bottom. A movable rod 83 is slidably connected inside each branch pipe 81. The top of each movable rod 83 is connected to the housing 4, and the bottom of each movable rod 83 has a second adjustment through hole corresponding to the position of the first adjustment through hole 82. The second adjustment through hole and one of the first adjustment through holes 82 are connected by a detachable connector. Specifically, the connector can be a bolted connection pair, i.e., the connector includes a third connecting bolt 84 and a locking nut 85. The first adjustment through holes 82 formed on the branch pipe 81... The adjustment through hole 82 passes through both sides of the branch pipe 81. In use, after the screw end of the third connecting bolt 84 passes through the first adjustment through hole 82 and the second adjustment through hole in sequence through the branch pipe 81 and the movable rod 83, the locking nut 85 can be fitted onto the third connecting bolt 84 to fix the position of the movable rod 83 on the branch pipe 81. Then, when it is necessary to adjust the height of the chassis 4, after removing the connector, the movable rod 83 can be slid along the branch pipe 81 until the second adjustment through hole is aligned with the other first adjustment through holes 82. Then, the connector can be used to fix the position of the movable rod 83 on the branch pipe 81 again to fix the height of the chassis 4.

[0033] In addition, a horizontally arranged support plate 86 is installed between the bottoms of the four support pipes 81. The support plate 86 can improve the connection strength between the four telescopic support legs to ensure the structural stability of the frame 8. Furthermore, the support plate 86 can also be used to place a material bucket to hold the waterproof plug 20 that drops material from the demolding box 42.

[0034] Furthermore, such as Figure 1 , Figure 7 and Figure 8 As shown, the bottom opening of the demolding box 42 is connected to a vertically distributed hopper 14. The hopper 14 is a frustum shape with a wider top and a narrower bottom. Specifically, during use, the material bucket can be placed below the hopper 14. By setting the hopper 14 and making it a frustum shape with a wider top and a narrower bottom, it is convenient to drop the waterproof plug 20 inside the demolding box 42 into the material bucket during use.

[0035] Furthermore, such as Figure 1 , Figure 3 and Figure 8 As shown, a touch screen control panel 7 electrically connected to the controller is embedded on the top surface of the electrical control box 41. By setting the touch screen control panel 7, it is convenient to input and adjust the operating parameters of various components electrically connected to the controller in the automatic demolding machine. In addition, a transparent protective plate 9 that can be opened and closed is installed on the touch screen control panel 7. Specifically, the transparent protective plate 9 can be set as a transparent acrylic plate. One side of the transparent protective plate 9 is hinged to the top surface of the electrical control box 41 so that the transparent protective plate 9 can be opened and closed. A pad 91 is installed on the other side of the protective plate 9. Specifically, when the transparent protective plate 9 is closed, it can prevent the operator from accidentally touching the touch screen control panel 7 and causing equipment failure. And the relevant parameters displayed on the touch screen control panel 7 can be observed in real time through the transparent protective plate 9. In addition, after the transparent protective plate 9 is closed, the pad 91 can make a gap between the transparent protective plate 9 and the top surface of the electrical control box 41 so as to facilitate opening the transparent protective plate 9.
