[0039] See also Figure 1 and Figure 2The utility model provides a pitting test mold, comprising a mold plate 1, two eccentric rollers 2, a double-axis motor 3, an anti-slide plate 4 and an auxiliary vibration mechanism 5. The two eccentric rollers 2 are mounted on the first surface 11 of the mold plate 1; the double-axis motor 3 is mounted on the first surface 11 and is located between the two eccentric rollers 2, and the two output shafts of the double-axis motor 3 are respectively connected to the two eccentric rollers 2; the anti-slide plate 4 is spaced apart from the mold plate 1; the auxiliary vibration mechanism 5 comprises an elastic member 51, and the opposite ends of the elastic member 51 are respectively arranged on the first surface 11 and the side of the anti-slide plate 4 facing the first surface 11.

[0040] In this way, the utility model provides a pitting test mold, by setting a double-axis motor 3 and two eccentric rollers 2, the two output shafts of the double-axis motor 3 are respectively connected to the two eccentric rollers 2, and the double-axis motor 3 is started to drive the eccentric rollers 2 to rotate. Due to the eccentric setting of the eccentric rollers 2, the eccentric rollers 2 will generate centrifugal force during the rotation process, and the eccentric rollers 2 are installed on the mold plate 1. During the rotation of the eccentric rollers 2, the mold plate 1 is driven to vibrate by the centrifugal force, so that the flow of the raw material is more uniform, and the uneven thickness of the mold plate 1 after the raw material is leveled is improved; by setting an elastic member 51, and the opposite ends of the elastic member 51 are respectively arranged on the mold plate 1 and the anti-slip plate 4, when the eccentric roller 2 drives the mold plate 1 to vibrate, the mold plate 1 can drive the elastic member 51 to vibrate. Since the elastic member 51 itself has elasticity, it can amplify the vibration frequency and vibration amplitude of the mold plate 1 through elastic force during the vibration process, thereby further enhancing the uniformity of the raw material flow.

[0041] See also Figure 2 In some embodiments, the auxiliary vibration mechanism 5 further includes a first fixed cover 52, a second fixed cover 53 and a connecting piece. The first fixed cover 52 is mounted on the first surface 11, and the second fixed cover 53 is mounted on the side of the anti-slip plate 4 facing the first surface 11. One end of the connecting piece and the second fixed cover 53 are penetrated through the second fixed cover 53 and are threadedly connected to the second fixed cover 53. The other end of the connecting piece is arranged on the inner wall of the first fixed cover 52. The elastic member 51 is sleeved on the connecting piece, and the opposite ends of the elastic member 51 are respectively connected to the inner wall of the first fixed cover 52 and the inner wall of the second fixed cover 53.

[0042] Among them, see Figure 1 In this embodiment, the first fixed cover 52 is fixedly connected to the first surface 11 of the mold plate 1; a first mounting through hole is provided on the anti-slip plate 4, the second fixed cover 53 is partially passed through the first mounting through hole, and the second fixed cover 53 is fixedly connected to the anti-slip plate 4.

[0043] See also Figure 2In some embodiments, the connecting member includes a screw 54 and a steel wire 55. The second fixing cover 53 is provided with a threaded through hole (not shown in the figure), and the screw 54 is passed through the threaded through hole. One end of the steel wire 55 is connected to the screw 54, and the other end is connected to the inner wall of the first fixing cover 52.

[0044] See also Figure 3 In some embodiments, a hexagonal groove 541 is provided on a side of the screw rod 54 facing away from the first fixing cover 52 .

[0045] In this way, by providing the hexagonal slot 541 , a hexagonal wrench can be inserted into the hexagonal slot 541 to drive the screw rod 54 to rotate, which is convenient for operation.

[0046] It is understandable that since the operating space of the first mounting through hole is relatively small, a hexagonal groove 541 is provided to facilitate the rotation of the screw 54. However, other suitable and convenient structures or other methods can be selected to rotate the screw 54 according to actual usage, and no excessive restrictions are made here.

[0047] In some embodiments, the elastic member 51 is a spring.

[0048] See also Figure 1 In this embodiment, four auxiliary vibration mechanisms 5 are arranged at intervals around the first surface 11 to enhance the vibration effect and make the raw material flow more uniform.

[0049] See also Figure 1 In some embodiments, the pitting test mold further includes a fixing frame 6 , which is mounted on the first surface 11 , and the two eccentric rollers 2 are both mounted on the fixing frame 6 .

[0050] Among them, in this embodiment, a plurality of fixing frames 6 are arranged at intervals along the width direction of the mold plate 1, and a second mounting through hole (not shown in the figure) is provided on the fixing frame 6, and the eccentric roller 2 is inserted into the second mounting through hole to facilitate the installation of the eccentric roller 2.

[0051] See also Figure 1 In some embodiments, the pitting test mold further includes a heat dissipation assembly 7, which includes a heat conducting plate 71, a semiconductor refrigerator 72, and a controller 73. The heat conducting plate 71 is mounted on the first surface 11, and the semiconductor refrigerator 72 is mounted on a side of the heat conducting plate 71 away from the first surface 11. The controller 73 is mounted on a side of the anti-slip plate 4 facing the first surface 11, and the controller 73 is in communication connection with the semiconductor refrigerator 72.

[0052] In this way, by setting up the controller 73 to control the operation of the semiconductor refrigerator 72, it is beneficial to improve the automation level of the pitting test mold; by setting up the heat conducting plate 71 and the semiconductor refrigerator 72, the heat conducting plate 71 can transfer the heat of the raw material to the cold end of the semiconductor refrigerator 72, and dissipate the heat through the hot end of the semiconductor refrigerator 72, thereby accelerating the cooling efficiency of the raw material and further improving the pitting test efficiency.

[0053] See also Figure 1 In some embodiments, an electric wire 74 is provided inside the semiconductor refrigerator 72 , and the controller 73 is connected to the semiconductor refrigerator 72 through the electric wire 74 .

[0054] See also Figure 4 In some embodiments, a main flow channel 13 is opened on the second surface 12 of the mold plate 1 , a pouring flow channel 14 is opened at the center of the main flow channel 13 , and the pouring flow channel 14 is connected to the main flow channel 13 .

[0055] See also Figure 4 In some embodiments, two cavity plates 15 are installed on the second surface 12, and the two cavity plates 15 are symmetrically located on both sides of the main channel 13 and are both connected to the main channel 13. The specification of each cavity plate 15 is 80mm*90mm*3mm.

[0056] The specific testing process of the utility model is as follows: during the test, the anti-slip plate 4 always remains stationary, is inserted into the hexagonal groove 541 through a hexagonal wrench, and the screw 54 is driven to rotate by the hexagonal wrench. During the rotation, the screw 54 can drive the first fixed cover 52 to move through the steel wire 55. Since the first fixed cover 52 is fixedly connected to the mold plate 1, it can also drive the mold plate 1 to move, thereby adjusting the distance between the first fixed cover 52 and the second fixed cover 53. By adjusting the distance between the first fixed cover 52 and the second fixed cover 53, the compression degree of the elastic member 51 can be adjusted. The compression degree of the elastic member 51 is different, and the vibration amplitude of the corresponding elastic member 51 is also different. After adjusting the distance between the first fixed cover 52 and the second fixed cover 53, pouring is performed into the two cavity plates 15, and then the dual-axis motor 3 is started, and the dual-axis motor 3 drives the two eccentric rollers 2 to rotate. The eccentric rollers 2 drive the mold plate 1 to vibrate through centrifugal force during the rotation process. The mold plate 1 drives the first fixed cover 52 to vibrate during the vibration process, and the first fixed cover 52 drives the elastic member 51 to vibrate. The elastic member 51 can amplify the vibration frequency and vibration amplitude of the mold plate 1 through elastic force during the vibration process, so that the raw material flow on the surface of the cavity plate 15 is more uniform. After the vibration is completed, the semiconductor refrigerator 72 is started, and the semiconductor refrigerator 72 can cool the mold plate 1 and the cavity plate 15 through the heat conducting plate 71, thereby accelerating the cooling efficiency of the raw materials, and then improving the efficiency of the pitting test.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
