[0015] 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.

[0016] Please see Figure 1-5 This utility model provides a technical solution: A sprue cutting device for automotive injection molded parts, comprising: The sealing box 1 has a lifting assembly 3 at its lower end for supporting the injection molded part. The top of the sealed box 1 is equipped with a cutting assembly 6 for cutting the sprue of the injection molded part; A dustproof plate 7 is fixedly connected to the inside of the side wall of the sealed box 1, and a dust collection component 8 is provided on the side of the sealed box 1 away from the dustproof plate 7 for collecting dust during cutting.

[0017] For example, the sealed box 1 serves as the main load-bearing space for the entire cutting operation, providing a relatively independent and stable environment for the cutting process. Two symmetrically distributed sealed doors 2 are provided on the side wall of the sealed box 1. When closed, they ensure that a relatively sealed space is formed inside the sealed box 1, preventing dust generated during the cutting process from leaking into the external environment. The sealed doors 2 are made of transparent material, making it easy to observe the inside of the sealed box 1. Through the flexible adjustment of the lifting component 3, the height position of the injection molded part inside the sealed box 1 can be precisely controlled to meet the processing needs of injection molded parts with different specifications and cutting requirements. The cutting component 6, as a core functional component, directly determines the quality and efficiency of the sprue cutting. It can perform efficient and precise cutting operations on the sprue of injection molded parts under precise control. The dustproof plate 7 can effectively block external dust from entering the interior of the sealed box 1, ensuring the cleanliness of the cutting environment and reducing the impact of dust on the cutting process and equipment. A large amount of dust is generated during the cutting process. The dust removal component 8 can collect this dust in time, preventing dust from spreading inside the sealed box 1. This not only improves the working environment but also prevents dust from damaging the equipment and extends the service life of the equipment.

[0018] The dust removal assembly 8 includes a collection pipe 81, an elastic plate 82, a fixing rod 83, a connecting ring 85, a filter plate 86, a hose 87, and a fan 88; The sealed box 1 is internally threaded with a collection pipe 81. Two symmetrically distributed elastic plates 82 are fixedly connected inside the collection pipe 81. A fixing rod 83 is fixedly connected inside the collection pipe 81. A cloth strip 84 is fixedly connected to the side wall of the fixing rod 83. The cloth strip 84 contacts the filter plate 86. A connecting ring 85 is internally threaded with the collection pipe 81. The filter plate 86 is fixedly connected inside the connecting ring 85. A hose 87 is threadedly connected to the outside of the connecting ring 85. A fan 88 is fixedly connected to the upper end of the hose 87. The fan 88 is fixedly connected to the sealed box 1.

[0019] For example, the sealed box 1 is internally threaded with a collection tube 81. This threaded connection makes the installation and removal of the collection tube 81 more convenient, and facilitates later cleaning and maintenance of the collection tube 81. The elastic plate 82 has a certain degree of elasticity and can deform when the airflow passes through, thereby buffering and blocking the dust in the airflow, making it easier for the dust to settle inside the collection tube 81. When the airflow passes through the cloth strip 84, the cloth strip 84 moves with the airflow, and then, with the swing of the cloth strip 84, it prevents the filter plate 86 from clogging (the figure is only a schematic diagram, the length of the cloth strip 84 is longer than shown in the figure, which facilitates the contact between the cloth strip 84 and the surface of the filter plate 86). The filter plate 86 is fixedly connected inside the connecting ring 85. Made of special filter material, it can effectively filter dust in the airflow, making the exhaust air cleaner. The hose 87 has a certain degree of flexibility and can be bent and adjusted according to the actual installation position, which facilitates the connection of the collection pipe 81 to the fan 88 and the disassembly of the collection pipe 81. The fan 88 is fixedly connected to the sealing box 1. When the fan 88 is working, it will generate a strong suction force, which will draw the dust-laden air in the sealing box 1 into the collection pipe 81. After being filtered by the filter plate 86, the clean air is discharged, thereby realizing the collection and purification of dust. When holding the hose 87, rotating the collection pipe 81 will cause the connecting ring 85 to rotate. At the same time, the collection pipe 81 is separated from the sealing box 1, and the connecting ring 85 is separated from the hose 87.

[0020] The lifting assembly 3 includes a fixed frame 31, a first motor 32, a first screw 33, a lifting frame 34, and a support platform 35; The lower end of the sealing box 1 is fixedly connected to a fixed frame 31, the inside of the fixed frame 31 is fixedly connected to a first motor 32, the output shaft of the first motor 32 is fixedly connected to a first screw 33, the outside of the first screw 33 is threadedly connected to a lifting frame 34, the lifting frame 34 is slidably connected to the sealing box 1, and the upper end of the lifting frame 34 is fixedly connected to a support platform 35.

[0021] For example, the fixed frame 31 provides a stable support structure for the entire lifting assembly 3, ensuring the stability of the lifting assembly 3 during operation. The first motor 32 serves as a power source, providing power for the operation of the lifting assembly 3. When the first motor 32 starts, it drives the first screw 33 to rotate. During the rotation of the first screw 33, due to the sliding restriction between the lifting frame 34 and the sealing box 1, the lifting frame 34 will move linearly along the axial direction of the first screw 33. The support platform 35 is used to place the injection molded part. By moving the lifting frame 34 up and down, the support platform 35 and the injection molded part can be lifted and lowered together, thereby achieving precise adjustment of the height of the injection molded part to meet the cutting requirements of the cutting assembly 6.

[0022] The cutting assembly 6 includes a fixed housing 61, a second motor 62, a second screw 63, a moving plate 64, and a cutting machine 66; The sealed box 1 has a fixed shell 61 fixedly connected to its inner top. A second motor 62 is fixedly connected inside the fixed shell 61. A second screw 63 is fixedly connected to the output shaft of the second motor 62. The second screw 63 is rotatably connected to the fixed shell 61. A movable plate 64 is threadedly connected to the outer side of the second screw 63. The movable plate 64 is slidably connected to the fixed shell 61. Two symmetrically distributed cleaning burr rings 65 are fixedly connected to the side wall of the movable plate 64. The two cleaning burr rings 65 are in contact with the second screw 63 respectively. A cutting machine 66 is fixedly connected to the lower end of the movable plate 64.

[0023] For example, the fixed housing 61 provides an installation and support platform for other components of the cutting assembly 6. The second motor 62 is the power device that drives the cutting assembly 6. When the second motor 62 is started, it drives the second screw 63 to rotate. During the rotation of the second screw 63, due to the sliding restriction between the moving plate 64 and the fixed housing 61, the moving plate 64 will move linearly along the axial direction of the second screw 63. The cleaning lint ring 65 cleans the surface of the second screw 63 during the movement of the moving plate 64 to prevent dust and impurities from adhering to the second screw 63 and affecting the normal rotation of the second screw 63 and the moving accuracy of the moving plate 64. The cutting machine 66 is the component that actually performs the cutting operation. By moving the moving plate 64, the cutting machine 66 can be moved in the horizontal direction, thereby realizing the cutting of different positions of the injection molding part's sprue.

[0024] Two symmetrically distributed electric push rods 4 are fixedly connected to the inner bottom of the sealed box 1, and clamping plates 5 are fixedly connected to the output ends of the two electric push rods 4.

[0025] For example, the electric push rod 4 is an actuator capable of linear motion. By controlling the extension and retraction of the electric push rod 4, the position of its output end can be adjusted. When it is necessary to clamp the injection molded part, the electric push rod 4 is activated, causing the output ends of the two electric push rods 4 to extend towards the middle at the same time, driving the clamping plate 5 to move closer to the injection molded part until the clamping plate 5 firmly clamps the injection molded part in the middle. This symmetrically distributed clamping method can make the injection molded part subject to uniform clamping force, ensuring the stability of the injection molded part during the cutting process, thereby improving the cutting accuracy and quality. In addition, a rubber plate is provided on the side wall of the clamping plate 5, which can protect the injection molded part when clamping it.

[0026] Working principle: First, open the sealing door 2 and place the automotive injection molded part to be cut on the support platform 35 at the bottom of the sealing box 1. Turn on the first motor 32. The first motor 32 drives the lifting frame 34 to rise and fall through the first screw 33. The lifting frame 34 drives the injection molded part on the support platform 35 to rise and fall together, thereby achieving precise adjustment of the height of the injection molded part. After the height of the injection molded part is adjusted to the right position, the output ends of the two electric push rods 4 extend to the middle at the same time, driving the clamping plate 5 to clamp the injection molded part. The second motor 62 is turned on, and the second motor 62 drives the moving plate 64 to move through the second screw 63. During the movement of the moving plate 64, the cleaning ring 65 cleans the surface of the second screw 63. As the moving plate 64 moves, the cutting machine 66 moves in the horizontal direction and cuts different positions of the injection molded part's sprue according to the preset cutting path and program. When the blower 88 is turned on, the blower 88 draws in the dust-laden air from the sealed box 1 through the collection pipe 81. When the dust-laden air passes through the collection pipe 81, the elastic plate 82 deforms as the airflow passes through, thus buffering and blocking the dust in the airflow, making it easier for the dust to settle in the collection pipe 81. When the airflow passes through the cloth strip 84, the cloth strip 84 moves with the airflow. Then, as the cloth strip 84 swings, it prevents the filter plate 86 from clogging, preventing dust from clogging the filter plate 86 and ensuring the filtration effect of the filter plate 86. The clean air filtered by the filter plate 86 is discharged through the hose 87, thereby realizing the collection and purification of dust. At the same time, the dustproof plate 7 fixedly connected inside the side wall of the sealed box 1 can effectively block external dust from entering the interior of the sealed box 1, ensuring the cleanliness of the cutting environment and reducing the impact of dust on the cutting process and equipment. After the cutting assembly 6 finishes cutting the sprue of the injection molded part, all components stop working. The operator opens the sealing door 2, removes the cut injection molded part from the support platform 35, and then closes the sealing door 2. The device returns to its initial state and waits for the next cutting task.

[0027] The control method of the first motor 32, electric push rod 4, second motor 62, and fan 88 in this application is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so the control method and circuit connection will not be explained in detail in this application. The device is powered by a built-in power supply or an external power supply.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
