Description

Technical Field

[0001] This utility model relates to the field of static press technology, and in particular to a static press mold changing device. Background Technology

[0002] A static press is a four-column press used for brick production. It typically uses stone powder, fly ash, slag, mineral slag, crushed stone, sand, and water as raw materials to produce cement bricks through static pressure. Static press brick machines offer stable force application, high pressure, and a high degree of automation, resulting in high-quality, high-strength bricks with standardized dimensions and a high yield rate.

[0003] However, during the mold loading or changing process of the static press, a forklift is needed to push or pull the slider of the static press onto the middle frame 2. Due to the unbalanced force during the pushing or pulling process of the forklift, the angle of pushing or pulling the middle frame 2 may deviate during the mold loading or changing process, which may cause jamming and affect the efficiency of mold loading or changing. Utility Model Content

[0004] This utility model discloses a static press mold changing device, which mainly solves the problem of imbalance that occurs when a forklift is used to push or pull out the middle frame 2 during the mold loading or changing of a traditional static press.

[0005] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: This utility model provides a die-changing device for a static press, including sliders symmetrically arranged on the static press, a middle frame disposed between the two sliders, and a lower die mounted on the middle frame. Each of the two sliders has a groove on one side facing the middle frame, and the middle frame has a boss at the position corresponding to the groove. The boss and the groove cooperate with each other. A die-changing hydraulic cylinder is installed between the two sliders along the sliding direction of the middle frame. The output end of the die-changing hydraulic cylinder is a piston rod, and the end of the piston rod is detachably connected to the middle frame, so that the die-changing hydraulic cylinder drives the middle frame to move along the groove on the slider.

[0006] In one embodiment, both ends of the boss are provided with inclined surfaces that are away from the slider.

[0007] In one embodiment, the piston rod of the mold-changing hydraulic cylinder is driven to extend and retract by a hydraulic pump, and the hydraulic pump is connected to the mold-changing hydraulic cylinder through an electromagnetic directional valve.

[0008] In one embodiment, a synchronization plate is connected between the two sliders, and the mold-changing hydraulic cylinder is mounted on the synchronization plate so that the piston rod passes through the synchronization plate.

[0009] In one embodiment, the synchronization plate is provided with a mounting base plate at the position corresponding to the mold changing hydraulic cylinder, and the mold changing hydraulic cylinder is mounted on the synchronization plate through the mounting base plate.

[0010] In one embodiment, the piston rod has a connecting flange at its end, which is detachably connected to the middle frame by means of hexagon socket screws.

[0011] The advantages or beneficial effects of the above technical solution include at least the following: During mold assembly, by cooperating with the boss of the middle frame and the groove of the slider, one end of the middle frame can be pre-guided into the groove by a small section. Then, the end of the piston rod of the mold changing hydraulic cylinder is connected to the middle frame, and the middle frame can be driven to move along the direction of the groove by the mold changing hydraulic cylinder. During mold changing, the middle frame is driven in the opposite direction by the mold changing hydraulic cylinder, so that the middle frame and the lower mold can be pushed out of the slider together. This avoids the need to use a forklift to push or pull out the middle frame, thus ensuring that the angle of pushing or pushing out the middle frame does not deviate, preventing jamming problems, and improving the efficiency of mold assembly or mold changing.

[0019] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0020] See Figure 1 and Figure 2This utility model provides a mold-changing device for a static press, including sliders 1 symmetrically arranged on the static press, a middle frame 2 disposed between the two sliders 1, and a lower mold 3 mounted on the middle frame 2. Each slider 1 has a groove 11 on the side facing the middle frame 2. The middle frame 2 has a boss 21 corresponding to the groove 11, which cooperates with the groove 11. A mold-changing hydraulic cylinder 4 is installed between the two sliders 1 along the sliding direction of the middle frame 2. The output end of the mold-changing hydraulic cylinder 4 is a piston rod 41, the end of which is detachably connected to the middle frame 2, allowing the mold-changing hydraulic cylinder 4 to drive the middle frame 2 to move along the direction of the groove 11 on the slider 1. The static press also includes an upper mold. The pressing of bricks is achieved through the upper mold, middle frame 2, and lower mold 3. The working principle of the static press is prior art and will not be described further.

[0021] With the above structure, during mold assembly, the boss 21 of the middle frame 2 and the groove 11 of the slider 1 cooperate to pre-guide one end of the middle frame 2 into the groove 11 by a small section. Then, the end of the piston rod 41 of the mold changing hydraulic cylinder 4 is connected to the middle frame 2, and the middle frame 2 can be driven to move along the direction of the groove 11 by the mold changing hydraulic cylinder 4. During mold changing, the mold changing hydraulic cylinder 4 drives the middle frame 2 in the opposite direction, so that the middle frame 2 and the lower mold 3 can be pushed out of the slider 1 together. This avoids the need to use a forklift to push or pull the middle frame 2, thus ensuring that the pushing or pushing angle of the middle frame 2 does not deviate, preventing jamming and improving the efficiency of mold assembly or mold changing.

[0022] In one embodiment, see Figure 2 Both ends of the boss 21 are provided with inclined surfaces 211 that are inclined away from the slider 1. In practical applications, the inclined surfaces 211 can facilitate the boss 21 to act as a guide during the process of embedding into the slider 1, so that the boss 21 can be embedded into the groove 11 of the slider 1.

[0023] In one embodiment, see Figures 1 to 4 The piston rod 41 of the mold-changing hydraulic cylinder 4 is driven to extend and retract by the hydraulic pump 5, which is connected to the mold-changing hydraulic cylinder 4 via an electromagnetic directional valve. In practical applications, the piston rod 41 of the mold-changing hydraulic cylinder 4 can extend and retract through the cooperation of the electromagnetic directional valve and the hydraulic pump 5, thereby driving the movement of the middle frame 2.

[0024] In one embodiment, see Figure 3 and Figure 4A synchronization plate 6 connects the two sliders 1, and the mold-changing hydraulic cylinder 4 is mounted on the synchronization plate 6, allowing the piston rod 41 to pass through it. The synchronization plate 6 may have holes for the piston rod 41 to pass through. In practical applications, the synchronization plate 6 ensures synchronized movement of the sliders 1 on the hydrostatic press and facilitates the installation of the mold-changing hydraulic cylinder 4 between the two sliders 1.

[0025] A mounting base plate 7 is provided on the synchronous plate 6 corresponding to the position of the mold-changing hydraulic cylinder 4. The mold-changing hydraulic cylinder 4 is mounted on the synchronous plate 6 via the mounting base plate 7. In practical applications, the mounting base plate 7 facilitates the mounting of the mold-changing hydraulic cylinder 4 onto the synchronous plate 6.

[0026] The piston rod 41 has a connecting flange 411 at its end, which is detachably connected to the middle frame 2 by hexagon socket screws. Four hexagon socket screws can be used to ensure the connection stability between the connecting flange 411 and the middle frame 2, and to further ensure that the pushing and pulling angles on both sides of the middle frame 2 do not shift when the piston rod 41 pushes and pulls.

[0027] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
