[0023] The cross section of the material discharge channel 2 is square, the top of the material discharge channel 2 is a material inlet 21, and the first material discharge port 22 and the second material discharge port 23 are respectively arranged on the two opposite side walls of the material discharge channel 2, and the first material discharge port 22 and the second material discharge port 23 are located at the bottom of the side wall. The first arc groove 24 and the second arc groove 25 are arranged on the adjacent side wall of the material discharge channel 2 where the first material discharge port 22 is located, and the first arc groove 24 is located above the second arc groove 25.

[0024] One end of the detection plate 1 is hingedly arranged above the unloading channel 2. The detection plate 1 can open or close the feed port 21. A gravity sensor is arranged on the detection plate 1. The gravity sensor is used to monitor the weight of the product on the detection plate 1. The gravity sensor is electrically connected to the controller. The gravity sensor can be a commercially available product and is not limited here. In actual use, a first slider 11 is arranged on the side of the detection plate 1 facing the first arc groove 25. The first slider 11 is embedded in the first arc groove 24 and slides along the first arc groove 24. The first motor is arranged on the unloading channel 2. The first motor is connected to the detection plate 1 to drive the detection plate 1 to rotate. The first motor is electrically connected to the controller.

[0025] The receiving plate (3) has a triangular cross section, and the baffle (4) is hinged to the top of the receiving plate (3). Specifically, the receiving plate 3 comprises a first part 31 and a second part 32, wherein the first part 31 is located at the bottom of the material discharge channel 2 and corresponds to the first discharge port 22, the first part 31 is arranged obliquely, one end of the first part 31 is located in the material discharge channel 2, and the end is higher than the other end, and the other end extends out of the material discharge channel 2 from the bottom of the first discharge port 22; the second part 32 is symmetrical to the first part 31, the higher end of the second part 32 is connected to the higher end of the first part 31, and the connection between the second part 32 and the first part 31 is located in the middle of the bottom of the material discharge channel 2.

[0026] The baffle 4 is located in the feed channel, one end of the baffle 4 is hinged to the higher end of the second part 32, and the other end of the baffle 4 can abut against the side wall of the first discharge port 22 or the second discharge port 23 of the feed channel 2, and when abutting, the other end of the baffle 4 is higher than the first discharge port 22 or the second discharge port 23. A second slider 41 is provided on the baffle 4 on the side facing the second arc groove 25, and the second slider 41 is embedded in the second arc groove 25 and slides along the second arc groove 25. The second motor is provided on the feed channel 2, and the second motor is connected to the baffle 4 to drive the baffle 4 to rotate, and the second motor is electrically connected to the controller.

[0027] There are two counting sensors, both of which are arranged on the material discharge channel 2 and correspond to the first discharge port 22 and the second discharge port 23 respectively, and are used to count the number of products passing through the first discharge port 22 and the second discharge port 23 respectively.

[0028] When the utility model is used, Figure 2 As shown, the detection plate 1 closes the feed port 21, and the injection molded product falls onto the detection plate 1. The gravity sensor monitors the weight of the product. If the weight is the same as the weight of the qualified product, it is necessary to discharge the product from the first discharge port 22, even if the second cylinder drives the baffle 4 to rotate, so that the top of the baffle 4 abuts against the side wall where the second discharge port 23 is located, that is, the baffle 4 closes the second discharge port 23, and the first cylinder drives the detection plate 1 to rotate, as shown in FIG. Figure 3 As shown, the product enters the discharge channel 2, and is discharged and collected from the first discharge port 22 along the baffle 4 and the first part 31. When each qualified product passes through the first discharge port 22, the corresponding counting sensor counts once. Therefore, the products discharged from the first discharge port 22 are all qualified products, and the total number of qualified products can be obtained. If the gravity sensor detects that the weight of the product on the detection plate 1 is lighter or heavier than the qualified product, it is a defective product and needs to be discharged from the second discharge port 23. Therefore, the products discharged from the second discharge port 23 are all defective products, and the total number of defective products can be obtained. Therefore, when the injection molding machine discharges materials, the qualified products and defective products can be automatically classified and counted, which improves work efficiency.
