[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example 1: This example provides a low-pressure casting equipment that allows for rapid demolding. See [link to example]. Figures 1-4 Specifically, it includes a machine body 1, a hydraulic cylinder 2 fixedly connected to the top of the machine body 1, a slide rod 3 slidably connected inside the hydraulic cylinder 2, a pressure plate 4 fixedly connected to the bottom of the slide rod 3, mounting plates 5 fixedly installed on both sides inside the machine body 1, a mold shell 6 fixedly connected between the two mounting plates 5, a base plate 7 fixedly connected inside the machine body 1, a cylinder 8 fixedly connected to the top of the base plate 7, a sliding shell 9 slidably connected inside the cylinder 8, a push rod 10 slidably connected inside the sliding shell 9, and a top plate 11 fixedly connected to the top of the push rod 10.
[0026] L-shaped plates 12 are fixedly connected to both sides of the outer side of the sliding shell 9. Multiple connecting shells 13 are fixedly connected to the inner side of the two L-shaped plates 12. Rotating rods 14 are connected between the multiple connecting shells 13 through bearings. Tough rubber plates 15 are fixedly connected to the outer side of the multiple rotating rods 14. A limiting plate 16 is provided at the bottom of the tough rubber plate 15. Two fixing plates 17 are fixedly connected to both sides of the outer side of the mold shell 6. Rotating plates 18 are movably connected between each pair of the four fixing plates 17 through rotating shafts.
[0027] In this embodiment, the slide rod 3 is slidably connected to the body 1, and the top rod 10 is also slidably connected to the body 1, which allows the slide rod 3 and the top rod 10 to slide.
[0028] In this embodiment, the top plate 11 is located inside the mold shell 6 and is in contact with the interior of the mold shell 6. Multiple connecting shells 13 are arranged in a linear shape, which allows the top plate 11 to eject the casting material.
[0029] In this embodiment, the limiting plate 16 is fixedly connected to one side of the L-shaped plate 12, and the limiting plate 16 is in contact with the outer surface of the flexible rubber plate 15, so that the L-shaped plate 12 can support and limit the limiting plate 16.
[0030] In this embodiment, the counterweight plate 19 is fixedly connected to one side of the rotating plate 18, and the top of the flexible rubber plate 15 is in contact with one side of the rotating plate 18, so that the rotating plate 18 can be accelerated by the counterweight plate 19.
[0031] In the specific implementation process, as shown in Figures 1-5 when the material forming work is needed, the worker needs to pour the external material into the inside of the mold shell 6, and then the worker opens the hydraulic cylinder 2, which controls the slide rod 3 and the pressing plate 4 to move downward to compact the material in the mold shell 6. When the material is formed, the air cylinder 8 needs to be opened, which controls the sliding shell 9 to move upward in the process of opening. The sliding shell 9 slides outside the top rod 10 in the process of moving, and the sliding shell 9 drives the L-shaped plate 12 to rise, which synchronously drives the connecting shell 13, the rotating rod 14 and the flexible rubber plate 15 to move. When the flexible rubber plate 15 is in contact with one side of the rotating plate 18, the rotating plate 18 is turned up at this time, and there is a large distance between the rotating plate 18 and the mold shell 6. If the flexible rubber plate 15 completely separates from one side of the rotating plate 18 in the process of rising, the rotating plate 18 will be quickly reset by the increased weight of the counterweight plate 19 and collide with the mold shell 6. This reciprocating can achieve the pre-vibration work of the material in the mold shell 6, so as to ensure the loosening of the material in the mold shell 6 and facilitate the subsequent demolding work.
[0032] In this embodiment, the two fixed rods 20 are fixedly connected to the outside of the rotating plate 18, and the two fixed rods 20 are fixedly connected to the strip plates 21 outside, which can facilitate the rotation of the rotating plate 18 and the strip plates 21.
[0033] In this embodiment, the two strip plates 21 are fixedly connected to the long plates 22, and one side of the long plate 22 is in contact with one side of the mold shell 6, so that the long plate 22 can impact and vibrate the different positions of the mold shell 6.
[0034] In the specific implementation process, as shown in Figure 5 the rotating plate 18 also synchronously drives the fixed rod 20 to rotate in the process of resetting and rotating, and the fixed rod 20 synchronously drives the strip plate 21 and the long plate 22 to rotate in the process of rotating. When the long plate 22 collides with one side of the mold shell 6, the materials in different positions of the mold shell 6 can be vibrated to ensure the integrity of demolding.
[0035] When the sliding shell 9 moves to a certain height and the bottom is in contact with the bottom of the top rod 10, the sliding shell 9 drives the top rod 10 and the top plate 11 to push upwards, and the top plate 11 drives the material to move synchronously in the process of pushing, so that the material can be conveniently demolded, and when the sliding shell 9 resets into the air cylinder 8, the sliding shell 9 drives the L-shaped plate 12, the connecting shell 13, the rotating rod 14 and the flexible rubber plate 15 to move downwards, then the arc surface of the flexible rubber plate 15 is in contact with one side of the rotating plate 18 and is guided to rotate, at this time, the flexible rubber plate 15 rotates away from one side of the limiting plate 16, so that the smoothness in the resetting process can be ensured.
[0036] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
