[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Example 1

[0035] See Figure 1-4 A casting device for manufacturing aluminum cylinders for motorcycle shock absorbers includes a main component 1, which includes: a base 11 with a side plate 12 fixedly connected to its top left side; a casting mechanism 13 disposed on the base 11; a fixing component 2 disposed on the base 11 and the side plate 12, the fixing component 2 including: a cavity 21 symmetrically opened on the right side wall of the side plate 12; a bidirectional lead screw 22 rotatably connected to the inside of the cavity 21; a threaded block 23 symmetrically and threadedly connected to the outside of the bidirectional lead screw 22; a motor 24 disposed on the front side wall of the side plate 12, the output shaft of the motor 24 being fixedly connected to the front end of the bidirectional lead screw 22; a fixing plate 25 symmetrically and slidably connected to the top of the base 11, the left side wall of the fixing plate 25 being fixedly connected to the threaded block 23; and a controller 26 disposed on the outer side wall of the side plate 12, the controller 26 being electrically connected to the motor 24 and the casting mechanism 13. The fixing plate 25 has symmetrically opened "V"-shaped grooves facing each other. A pressure sensor 3 is provided on the inner sidewall of a "V"-shaped groove of the fixing plate 25. The pressure sensor 3 is electrically connected to the motor 24 through the controller 26.

[0036] In use, the operator places the molds sequentially between the fixed plates 25 and starts the motor 24 via the controller 26. After starting, the motor 24 drives the bidirectional lead screw 22 to rotate. The threaded block 23 connected to the bidirectional lead screw 22 causes the fixed plates 25 to move closer together, clamping the mold in the middle. The controller 26 then controls the casting mechanism 13 to cast the mold below. Because the mold is fixed by the movable fixed plates 25, the stability of the casting process is increased, and it facilitates fixing molds of different diameters within a certain range, thus increasing the device's practicality. During the process of fixing the mold with the fixed plates 25, the outer wall of the mold contacts the "V"-shaped groove on the fixed plates 25. The "V"-shaped groove increases the contact area between the fixed plates 25 and the mold, further increasing the stability when fixing cylindrical molds. Meanwhile, when the mold applies pressure to the inner wall of the "V"-shaped groove of the fixing plate 25, the pressure sensor 3 monitors the pressure. When the pressure value reaches the preset threshold, the pressure sensor 3 sends the pressure data to the controller 26 via an electrical signal. The controller 26 sends a shut-off signal to the motor 24, and the fixing plate 25 stops moving. This allows the fixing plate 25 to stably clamp the mold while avoiding damage to the mold, which would affect the quality of the finished product after casting.

[0037] The aforementioned casting mechanism 13 employs conventional techniques, including a conveying pipe connecting to the external molten aluminum, a ladle for holding the molten aluminum, and a casting nozzle. The pipe delivers the molten aluminum to the ladle, and the casting nozzle delivers the molten aluminum to the mold. The goal is simply to achieve casting of the aluminum cylinder mold; the specific structure will not be detailed here. The pressure sensor 3 is equipped with a built-in power supply. When the mold applies pressure to the inner wall of the "V"-shaped groove on the fixed plate 25, the resistance value of the sensitive element in the pressure sensor 3 changes with the pressure. The measuring circuit measures the change in resistance value and converts it into a corresponding voltage or current signal change. After amplification and processing, an electrical signal corresponding to the mold pressure can be obtained, thereby achieving the detection of mold pressure.

[0038] Example 2

[0039] An auxiliary function has been added based on Embodiment 1.

[0040] See Figure 1-4 The inner sidewalls of the "V"-shaped grooves of the fixing plate 25 are all provided with protective pads 251. Slider 4s are symmetrically and fixedly connected to the right sidewall of the fixing plate 25. A sliding rod 41 is fixedly connected between the base 11 and the casting mechanism 13, and the sliders 4 are all slidably connected to the outside of the sliding rod 41. Telescopic shells 27 are symmetrically arranged between the cavity 21 and the threaded block 23.

[0041] When the fixing plate 25 clamps the mold, a rubber protective pad 251 is typically used to contact the outer wall of the mold. The protective pad 251 protects the mold while increasing the friction between the fixing plate 25 and the mold, further enhancing the clamping effect. When the threaded block 23 moves the fixing plate 25, the fixing plate 25 causes the slider 4 to slide on the slide rod 41. The slider 4 and slide rod 41 guide the other end of the fixing plate 25, thereby increasing the stability of the fixing plate 25 during movement and facilitating the fixation of the mold. When the threaded block 23 moves, the telescopic shell 27 connected to the threaded block 23 extends and retracts with the movement of the threaded block 23. When the threaded blocks 23 move closer to each other, the telescopic shell 27 in the middle of the threaded block 23 contracts and the telescopic shell 27 on the outside extends. When the threaded blocks 23 move away from each other, the telescopic shell 27 in the middle of the threaded block 23 contracts and the telescopic shell 27 on the outside extends. The telescopic shell 27 blocks the cavity 21 to prevent dust or foreign objects from entering the cavity 21 and affecting the normal movement of the bidirectional lead screw 22 and the threaded block 23.
