Description

Technical Field

[0001] This utility model relates to the field of mold opening and closing technology for large lightweight wall panel mold boxes, specifically to an automatic mold opening and closing device for large lightweight wall panel mold boxes. Background Technology

[0002] In industrial production, handling large mold boxes often requires a significant amount of manpower and time to open the vertical mold. Traditional methods are mostly manual, requiring workers to use simple tools such as pry bars and wrenches to loosen the latches on all four sides of the mold box one by one, and then manually tilt the mold. This process not only demands strong physical strength and endurance from workers, but is also cumbersome, often taking several hours to process each mold box, severely hindering production efficiency. Not only is it inefficient, but during the loosening process, residual stress inside the mold box can cause the latches to suddenly spring open, easily resulting in hand injuries to workers. Furthermore, when tilting the mold, if the mold's center of gravity is unstable or the worker applies improper force, the mold may tip over, causing workers to be crushed. Such accidents are frequent and pose a significant threat to workers' lives.

[0003] Meanwhile, some existing automatic opening devices have complex structures and high costs. They integrate a large number of mechanical transmission components, electrical control components, and complex connection lines. This not only increases the difficulty and cost of manufacturing the equipment, making the purchase price of the equipment high and deterring many small and medium-sized enterprises, but also makes the maintenance and upkeep of the equipment much more difficult. Frequent failures and repairs further increase the cost of use.

[0004] Therefore, an automatic mold opening and closing device for large lightweight wall panel mold boxes is needed to solve the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4As shown, the automatic opening and closing mold box for large lightweight wall panel provided by this utility model includes a base 1. A tapered guide bar 2 is symmetrically fixedly connected to the top of the base 1. A base plate 3 is provided on the top of the base 1. A first side plate 4 is symmetrically hinged to the top of the base plate 3. A slot is symmetrically formed on the inner wall of the first side plate 4, and a second side plate 5 is engaged inside the slot. A lock 6 is symmetrically fixedly connected to the surface of the second side plate 5, and the lock 6 engages with the first side plate 4. A convex-shaped sliding groove 7 is symmetrically formed on the surface of the first side plate 4. A slider 8 is slidably connected inside the sliding groove 7. A snap-fit ​​component 9 is slidably connected to the surface of the slider 8. A snap-fit ​​interface 10 is formed on the surface of the snap-fit ​​component 9. A transmission groove 11 is symmetrically formed on the front and back of the base 1. A transmission rod 12 is rotatably connected inside the transmission groove 11, and the transmission rod 12 is driven by a transmission motor. A threaded block 13 is connected to the threaded surface and is slidably connected to the transmission groove 11. A hinge 14 is fixedly connected to the surface of the threaded block 13 and is driven by a deflection motor. A hydraulic push rod 15 is hinged inside the hinge 14. A bidirectional push rod 16 is fixedly connected to the output end of the hydraulic push rod 15 and passes through the card interface 10 to cooperate with the lock 6. A control unit is fixedly connected to the top of the base 1. The control unit adopts a programmable logic controller (PLC). It receives signals from the drive motor, deflection motor, hydraulic push rod 15 and bidirectional push rod 16, and controls the action sequence and running status of the drive motor, deflection motor, hydraulic push rod 15 and bidirectional push rod 16 according to a preset program. The PLC controller that realizes this function is existing technology, such as a Siemens S7-200CN controller.

[0022] refer to Figure 1 and Figure 2 One end of the tapered guide bar 2 is fixedly connected to a limiting block 17, and a pressure sensor 18 is fixedly connected inside the limiting block 17.

[0023] As a technical optimization of this utility model, by setting up the limiting block 17 and the pressure sensor 18, the pressure sensor 18 detects that the pressure applied to the bottom plate 3 of the mold box reaches a preset threshold, and determines that the mold box has reached the designated position, thereby facilitating its positioning.

[0024] refer to Figure 1 and Figure 2 The top of the base 1 is symmetrically provided with multiple positioning grooves 19. The positioning grooves 19 are rotatably connected to positioning pins 20. The surface of the positioning pins 20 is threadedly connected to positioning blocks 21, and the positioning blocks 21 are slidably connected to the positioning grooves 19. The surface of the tapered guide strip 2 is provided with several openings 22, and the several openings 22 correspond one-to-one with the multiple positioning grooves 19.

[0025] As a technical optimization of this utility model, by setting up the positioning groove 19, positioning column 20, positioning block 21 and through 22, the corresponding positioning block 21 can be translated according to the size of the base plate 3, thereby blocking its movement trajectory and achieving the effect of positioning the base plate 3.

[0026] refer to Figure 2 Two positioning pins 20 located on the same straight line pass through the base 1 at one end and are driven by the same bidirectional motor (not shown). The threaded surfaces of the two positioning pins 20 located on the same straight line are arranged in opposite directions.

[0027] As a technical optimization of this utility model, by setting a bidirectional motor, two symmetrical positioning columns 20 can be driven to rotate. Then, by setting the threaded surfaces of the two positioning columns 20 located on the same straight line in opposite directions, the two symmetrical positioning blocks 21 can move synchronously relative to each other or in opposite directions.

[0028] refer to Figure 1 and Figure 3 Limiting blocks are symmetrically fixedly connected to the surface of the first side plate 4, and the limiting blocks are used in conjunction with the lock 6.

[0029] As a technical optimization of this utility model, by setting the limiting block, the locking of the lock 6 can be restricted, so that it can be locked between the two limiting blocks.

[0030] refer to Figure 1 and Figure 2 The top of the base 1 has several auxiliary slots, which are evenly arranged, and the inside of the auxiliary slots is connected to rollers 23.

[0031] As a technical optimization of this utility model, by setting the auxiliary groove and the roller 23, the sliding friction between the base plate 3 and the base 1 can be converted into rolling friction, thereby making the base plate 3 move more smoothly.

[0032] The working principle and usage process of this utility model are as follows: When using this automatic mold opening and closing device to open the mold of a large lightweight wall panel, the large mold is first transported to the designated area of ​​the base 1 by an external transport device. Then, the bottom plate 3 of the large mold is guided by the tapered guide bar 2, causing it to move to contact the limiting block 17. At this time, the pressure sensor 18 detects that the pressure applied to the bottom plate 3 has reached a preset threshold, indicating that the large mold has reached the designated position. This activates the bidirectional motor at the corresponding position to drive the two positioning columns 20 to rotate, thereby causing the positioning block 21 at the corresponding position to move relative to each other, so that it abuts against the bottom plate 3, thus achieving the effect of positioning the large mold. Then, the control unit starts the transmission motor to drive the transmission rod 12 to rotate, causing the threaded block 13 to drive the hydraulic push rod 15 to move. Move the device to the designated position, then start the deflection motor to drive the hydraulic push rod 15 to deflect. At the same time, start the hydraulic push rod 15 to push the bidirectional push rod 16 into the locking interface 10 of the locking piece 9 for locking. Then start the bidirectional push rod 16 so that its output end passes through the locking interface 10. At this time, use the thrust of the hydraulic push rod 15 to push the slider 8 on the locking piece 9 to move upward along the slide groove 7 on the first side plate 4, so that it reaches the point where the bidirectional push rod 16 is parallel to the lock 6. Then start the bidirectional push rod 16 so that it can block the lock 6 and unlock it. Then, using the combined action of the deflection motor and the hydraulic push rod 15, the output end of the bidirectional push rod 16 can pull the locking piece 9, thereby tilting the first side plate 4 until it is fully opened, thus achieving the effect of automatic mold opening for large mold boxes of lightweight wall panels.
