Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment: Refer to Figures 1-5 a shakeout machine for casting shown in the figure, including a box body 1. A crushing mechanism is provided at the bottom of the box body 1. The crushing mechanism utilizes the vibration generated by the vibration source to perform a frequency-controlled lifting movement to crush the falling molding sand and prevent it from agglomerating and caking during the falling process; and a separating mechanism is provided above the screen of the box body 1. The separating mechanism can divide the space above the screen into several spaces, effectively separating the casting parts and the molding sand, and avoiding the mutual stacking of the two during the processing process, resulting in the influence on the processing efficiency.

[0024] Crushing mechanism: An activity slot 104 is provided on the inner wall of the box body 1, and a limiting slot 105 is provided on the inner wall of the activity slot 104. A positioning rod 8 is provided in the limiting slot 105, and a slide plate 10 is slidably connected to the positioning rod 8 (the slide plate 10 is adapted to the limiting slot 105 to achieve the limiting purpose, so that the slide plate 10 can only perform lifting movement). Two groups of springs 9 are sleeved on the positioning rod 8, and the slide plate 10 is located between the two groups of springs 9. A crushing screen 11 is installed on the outer wall of the slide plate 10 (the crushing screen 11 is in the shape of a comb and is adapted to the internal space of the box body 1 as a whole). When the molding sand falls from above, through the power of the vibration source, the slide plate 10 on the positioning rod 8 performs lifting movement, squeezing the upper and lower springs 9. The springs 9 react the force on the slide plate 10 and transmit it to the crushing screen 11 to crush the agglomerated molding sand for recycling and reuse.

[0025] To prevent the molding sand from entering the limiting slot 105 and eroding the spring 9, a protective plate 12 is provided between the crushing screen 11 and the slide plate 10. The specification of the protective plate 12 is larger than the limiting slot 105 and smaller than the activity slot 104, so that during the lifting movement, the limiting slot 105 is always blocked to protect the spring 9.

[0026] The top section of the comb teeth of the crushing screen 11 is conical to facilitate the crushing of the agglomerated molding sand.

[0027] Partition mechanism: Four groups of sliding slots 101 are provided on the outer wall of the box body 1. Two opposite groups of sliding slots 101 are at the same horizontal height (front and back, left and right are at the same height). A sliding hole 102 communicating with the inside of the box body 1 is provided on the inner wall of the sliding slot 101, and a limiting channel 103 is provided on the inner top surface of the sliding slot 101 (for the front and back sliding slots 101 and the left and right sliding slots 101, there is a group of limiting channels 103 communicating with the top surface respectively). A first slider 2 and a second slider 3 are respectively provided in two opposite groups of sliding slots 101. A first limiting block 4 and a second limiting block 5 are respectively provided on the top surfaces of the first slider 2 and the second slider 3 (the difference between the second limiting block 5 and the first limiting block 4 is that a screw hole is provided on the top surface of the second limiting block 5, so the limiting channel 103 where the second limiting block 5 is located communicates with the outside). A positioning bolt 6 is threadedly connected to the top surface of the second limiting block 5. Its function is to press the top surface of the box body 1 by tightening the positioning bolt 6, so as to fix the position of the second limiting block 5. A positioning hole 301 is provided at the inner end surface of the second slider 3, and a chamfer is provided at the port of the positioning hole 301 (for the positioning insertion of the partition rod 7). A through hole 201 is provided on the first slider 2. The partition rod 7 passes through the through hole 201 and abuts into the positioning hole 301. And a set screw hole is provided on the inner wall of the through hole 201, and a set screw 202 is screwed into the set screw hole to limit the partition rod 7 for easy installation and disassembly.

[0028] The working principle of this utility model: According to the specifications of the casting parts, the separating rod 7 can be correspondingly toggled to make the separating rod 7 adapt to different casting parts. Subsequently, by rotating the positioning bolt 6, the second slider 3 and the second limiting block 5 are limited. Then, the vibration source is started to control the vibration of the box body. During the vibration process, the vibration sensation is transmitted to the springs 9 in the limiting grooves 105. The two groups of springs 9 work to drive the sliding plate 10 to lift and lower on the positioning rod 8 in cooperation with the springs 9. Thus, the sliding plate 10 drives the crushing net 11 to lift and lower in the box body 1 through the protective plate 12 to crush the falling molding sand and prevent caking.

[0029] By loosening the setscrew 202 on the first slider 2, the limitation on the separating rod 7 is released. Subsequently, the separating rod 7 is pulled out from the positioning hole 301 and the through hole 201 of the second slider 3 for maintenance and replacement. The first slider 2, the second slider 3 and the separating rod 7 are limited through the sliding groove 101 and the sliding hole 102, and the limiting channel 103 limits the first limiting block 4, the second limiting block 5 and the positioning bolt 6.
