In addition, the directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., are only references to the directions in the attached drawings. The directional terms used are for better and clearer explanation and understanding of the present utility model, rather than indicating or implying the orientation that the present utility model must have. Therefore, it should not be construed as a limitation to the present utility model.

[0019] As shown in the embodiments of the present utility model Figures 1 to 3 a kind of ultrasonic gate-cutting device, comprising a chassis 1. At the top of the chassis 1, there are two vertically arranged plates 2 arranged side by side at intervals. The two vertically arranged plates 2 extend in the front-rear direction. At the top of the two vertically arranged plates 2, there is a first sliding plate 3 with an octagonal cross-section, that is, the left part of the first sliding plate 3 slopes downward to the left, and the right part of the first sliding plate 3 slopes downward to the right. The middle line position of the first sliding plate 3 in the front-rear direction is the highest point. The inclined ends of the first sliding plate 3 away from the highest point are correspondingly connected to the tops of the two vertically arranged plates 2, that is, the left lower end and the right lower end of the first sliding plate 3 are correspondingly connected to the tops of the two vertically arranged plates 2. Inside the chassis 1, there is an ultrasonic generator 4. An ultrasonic transducer 5 is arranged on the ultrasonic generator 4. At the middle position of the highest point of the first sliding plate 3, there is an avoidance through hole 30 for avoiding the ultrasonic transducer 5, that is, there is a gap between the inner wall of the avoidance through hole 30 and the ultrasonic transducer 5. The top end of the ultrasonic transducer 5 sequentially passes through the top of the chassis 1 and the avoidance through hole 30. At the end of the ultrasonic transducer 5 away from the ultrasonic generator 4, there is an ultrasonic vibration head 6. A chassis door 10 is arranged on the front side wall of the chassis 1, which is convenient for adjusting or maintaining the ultrasonic generator 4 inside the chassis 1.

[0020] The ultrasonic generator 4 makes the ultrasonic vibration head 6 vibrate through the ultrasonic transducer 5. The manipulator on the injection molding machine places the connected gate and product on the ultrasonic vibration 6 head. The joint between the gate and the product breaks, and the product falls from the gate onto the first sliding plate 3. The product slides out along the first sliding plate 3, which is convenient for collecting the dropped products. In order to prevent the ultrasonic transducer 5 from transmitting vibration and affecting the first sliding plate 3, the ultrasonic transducer 5 is avoided through the avoidance through hole 30. With the first sliding plate 3 having an octagonal cross-section, the product will slide to the left and right sides and will not slide into the gap between the avoidance through hole 30 and the ultrasonic transducer 5.

[0021] Further improvements, such as Figure 1 and Figure 3 As shown in Figure 3 , inclined second slide plates 20 are provided on the side walls of the two vertical plates 2 that are away from each other. The two second slide plates 20 are inclined along the length direction of the vertical plate 2, that is, the second slide plates 20 extend in the front-back direction. The rear end of the second slide plate 20 is higher than the front end of the second slide plate 20. A surrounding plate 7 is provided on the chassis 1 to surround the first slide plate 3, the second slide plate 20, and the ultrasonic vibration head 6. Two discharge ports are provided at the front end of the surrounding plate 7. The two discharge ports are correspondingly located at the lowest positions of the two second slide plates 20. That is, after the product slides from the first slide plate 3 onto the two second slide plates 20, it slides out of the device along the corresponding second slide plate 20 from the discharge port. The two second slide plates 20 enable the product to discharge from the front end of the surrounding plate 7, facilitating the collection of the product. The surrounding plate 7 prevents the product from falling out of the device at other positions than the discharge port.

[0022] Further improvements, such as Figure 3 As shown in Figure 3 , the surrounding plate 7 is provided with inclined guide pipes 70 at the position of each discharge port. The guide pipes 70 cover the corresponding discharge ports. The guide pipes 70 are square pipe structures. The product slides from the second slide plate 20 into the corresponding guide pipe 70, and a box or conveyor belt for collecting the product is placed directly below the two guide pipes 70. The product slides from the guide pipe 70 into the box or conveyor belt for collecting the product.

[0023] Further improvements, such as Figure 1 and Figure 3 As shown in Figure 3 , a photoelectric sensor 8 is provided on the inner wall at the rear end of the surrounding plate 7. The photoelectric sensor 8 faces the ultrasonic vibration head 6. By the photoelectric sensor 8, it senses whether there is a sprue and a product approaching the ultrasonic vibration head 6, and cooperates with the positions of the sprue and the product to turn on and off the ultrasonic generator 4.

[0024] Further improvements, such as Figure 1 and Figure 2 As shown in Figure 2 , the ultrasonic vibration head 6 includes a connecting portion 60 and a cutting portion 61. The connecting portion 60 and the cutting portion 61 are integrally formed. The bottom end of the connecting portion 60 is connected to the ultrasonic transducer 5. The connecting portion 60 covers the avoidance through hole 30. The cutting portion 61 is provided at the top end of the connecting portion 60. A strip-shaped groove 62 is provided at the top end of the cutting portion 61. The groove 62 extends in the front-back direction, and the front and rear ends of the groove 62 are open structures. After the product falls from the sprue, the connecting portion can prevent the product from falling into the gap between the avoidance through hole 30 and the ultrasonic transducer 5, and the groove 62 can avoid the plastic at the position of the sprue hook needle on the sprue.

[0025] Further improvements, such as Figure 1 and Figure 3As shown in the figure, a fan 9 and a support frame for supporting the fan 9 are provided on the chassis 1 above the ultrasonic vibration head 6. The fan 9 is used to cool the products and gates just taken out from the plastic mold, preventing the products and gates from softening due to overheating and being incompletely broken when the ultrasonic vibration head 6 cuts the gates, and preventing part of the gates from remaining on the products.

[0026] It should be understood that those of ordinary skill in the art can make improvements or transformations according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
