[0023] Refer to Figures 1 to 4 , the gate cutting device for injection molded products, includes a main body 1 and a punching workbench 3. A manipulator 10 is slidably connected to the outer side wall of the main body 1. A grasping mechanism 2 is fixedly connected to the bottom of the manipulator 10. There is a cavity inside the punching workbench 3, and a conveyor line 7 penetrating the punching workbench 3 is connected inside the cavity. A clamping and feeding mechanism 5 is fixedly connected to the top of the punching workbench 3. A downward punching cutter mechanism 11 is fixedly connected to the top of the punching workbench 3. A plurality of sliding wheels 9 are fixedly connected to the bottom of the punching workbench 3.

[0024] The punching workbench 3 is the core part of the entire device. It not only bears all the operation processes but also integrates control and monitoring functions. The cavity inside the punching workbench 3 is used to accommodate the conveyor line 7 and other related components. The punching workbench 3 can be designed as a box structure with reinforcing ribs to enhance its rigidity and stability. The punching workbench 3 is also equipped with a protective cover 4 and an emergency stop button 8 to ensure the safety of the operators.

[0025] The grasping mechanism 2 includes a mounting plate 203. A vacuum chuck 201 is fixedly connected to the outer side wall of the mounting plate 203. A fixture 202 is connected to the outer side wall of the mounting plate 203. A plurality of vacuum chucks 201 can adsorb multiple positions of the product.

[0026] The clamping and feeding mechanism 5 includes two slide rails 504. The two slide rails 504 are fixedly connected to the top of the punching workbench 3. A slide table 505 is slidably connected to the top of the slide rail 504. A positioning groove matching the shape of the injection molded product is provided on the slide table 505. A plurality of sample molds 502 are fixedly connected to the top of the slide table 505. Each sample mold 502 is fixedly connected with a positioning cylinder 503.

[0027] The design of the slide rails 504 and the slide table 505 enables the clamping and feeding mechanism 5 to be adjusted according to the size of the product, so as to adapt to products of different specifications. The positioning cylinder 503 is used to provide sufficient clamping force to ensure that the product will not be displaced during the punching process.

[0028] The downward punching knife mechanism 11 includes a frame body 1101, which is fixed on the top of the punching table 3. A punching cylinder 1102 is fixedly connected to the top of the frame body 1101. The output end of the punching cylinder 1102 is fixedly connected to a pushing plate, and a plurality of punching heads 1104 are fixedly connected to the bottom of the pushing plate.

[0029] The punching cylinder 1102 ensures a quick and accurate punching action. The number and layout of the punching heads 1104 can be customized according to the number and position of the product's gates to achieve efficient batch processing.

[0030] A protective cover 4 is fixedly connected to the top of the punching table 3. The protective cover 4 is made of transparent impact-resistant material, which not only ensures good visibility but also provides necessary safety. Polycarbonate sheets can be used as the material for the protective cover. This material not only has high transparency but also has good impact resistance.

[0031] An emergency stop button 8 is electrically connected to the top of the punching table 3. This is an important safety measure. When someone opens the door, the work stops. The operator can stop the entire device immediately by pressing this button.

[0032] An inductive switch 1103 is electrically connected to the top of the frame body 1101. The inductive switch 1103 can detect whether the injection-molded product is placed in place, and only when the product is fully positioned can the gate cutting program be started.

[0033] The specific working principle of the present utility model is as follows:

[0034] In the initial state, when using this cutting device, first, the manipulator 10 takes out the product to be processed from the mold, and the vacuum suction cup 201 and the fixture 202 on the grasping mechanism 2 are used to stably grasp the product. Subsequently, the manipulator 10 moves the product above the punching table 3. At this time, the positioning cylinder 503 in the clamping and feeding mechanism 5 drives the sample die 502 to rise, and the sample die 502 cooperates with the positioning groove on the sliding table 505 to ensure that the product is accurately positioned at the predetermined position. To ensure operation safety, the whole process is carried out inside the protective cover 4 made of transparent impact-resistant material. At the same time, an emergency stop button 8 is also equipped on the top of the punching table 3 to immediately stop the operation of the equipment in case of an emergency. Once the product is correctly placed and positioned, the induction switch 1103 on the top of the frame body 1101 will detect that the product is in place and send a signal to the control system to start the gate cutting program. At this time, the punching cylinder 1102 in the downward pressing punch mechanism 11 starts to act, pushing the punch 1104 to move downward to accurately cut the gate position on the product. After the cutting is completed, the punch 1104 returns to its original position, and the positioning cylinder 503 in the clamping and feeding mechanism 5 drives the sample die 502 to descend, so that the product is out of the positioning state. Finally, the manipulator 10 acts again, uses the grasping mechanism 2 to move the product with the gate cut out of the punching table 3, and places it on the conveyor line 7. The conveyor line 7 sends the product to the next process or the collection area. During the whole process, the sliding wheel 9 ensures that the punching table 3 can be conveniently moved, facilitating maintenance and position adjustment. Through the coordinated action of the above components, the gate cutting device for the injection molded product realizes automatic, efficient and safe gate cutting operation.

[0035] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitution or change, and should be covered within the protection scope of the present invention.
