[0002] A washing machine is a device that can automatically wash clothes, making it more convenient for people to wash clothes. During the production process of the washing machine, many injection molded parts need to be assembled. Because injection molded parts will cause burrs on the edges of the injection molded parts during the production process, the burrs of the injection molded parts need to be cut off when they are used, so that the injection molded parts will not affect the normal operation and assembly of the washing machine during the assembly process.

[0003] Patent publication number CN216635077U discloses a burr removal tooling for the production of injection molded parts of washing machine accessories, which relates to the technical field of injection molded parts processing, including a workbench, a slide rail is symmetrically arranged on one side of the top of the workbench, fixed blocks are symmetrically arranged at both ends between the two slide rails, a screw is rotatably arranged between the two fixed blocks, and one end of the screw passes through the fixed block and is connected to a motor, a moving block is threadedly matched on the screw, a fixed plate is fixed on the moving block, a slider is symmetrically arranged at the bottom of the fixed plate, and the two sliders are respectively slidably matched with the two slide rails, a tool body is fixed on the fixed plate, a tool holder is arranged on one side of the tool body, a cutter is arranged at the bottom of the tool holder, and a detachable connecting component is arranged between the tool holder and the cutter, which realizes improving the accuracy of burr removal of injection molded parts and reducing production Cost, and through the electromagnetic connection between the tool holder and the cutter, when the tool needs to be replaced, the battery can be turned off to achieve the replacement of the tool, which is extremely convenient. However, the device does not have a positioning mechanism when removing the burrs of the injection molded parts, so that when the device removes the burrs of the injection molded parts, it is necessary to manually observe the contact point between the burrs of the injection molded parts and the tool with the naked eye, so as to adjust the position of the injection molded parts for burr removal. Because the accuracy of manually observing and judging the burr removal position of the injection molded parts with the naked eye is low, the injection molded parts are not accurate enough when removing the burrs, which makes it easy for the injection molded parts to be removed too much or too little when removing the burrs, which not only easily wastes raw materials, but also requires secondary processing of many removed parts, which not only affects work efficiency, but also increases the workload of staff.

By placing the injection molded part on the workbench 1, the positioning plate 10 and the fixing plate 7 are connected through the round shell 8 and the round rod 9 and the first spring; the positioning plate 10 has a telescopic extrusion effect, so that the positioning plate 10 can be pressed on the top of the outer wall of the injection molded part, so that the positioning plate 10 cooperates with the workbench 1 to extrude and fix the injection molded part under the elastic force of the first spring, and the outer wall side of the positioning plate 10 is in the same plane as the tip of the cutting knife 5, so that when the injection molded part is placed, the burrs will need to be cut off. The part is placed on one side of the outer wall of the positioning plate 10 and the other side, so that the part beyond the positioning plate 10 is the cut-off part, so that the staff can clearly observe the part of the injection molded part to be cut off, so that the staff can adjust the position of the injection molded part before cutting, so that the part of the injection molded part to be cut off is located outside the outer wall of the positioning plate 10, so that the device will not cut too much or too little when cutting the burrs of the injection molded part, so that the device will not waste raw materials and does not need secondary processing, thereby improving work efficiency and reducing the workload of the staff. When the injection molded part is placed, the motor 3 drives the threaded shaft 6 to rotate. Because the threaded shaft 6 is threadedly connected to the sliding plate 4, The rotation of the threaded shaft 6 moves the sliding plate 4, and the movement of the sliding plate 4 drives the cutting knife 5 to move, so that the cutting knife 5 cuts off the burrs of the injection molded parts outside the positioning plate 10 that need to be cut off, thereby making the cutting operation of the device simple and convenient, and also making the cutting operation more accurate.

At this time, the extension plate 102 will retract into the first through groove 13, so that the clamping plate 12 is not easily affected by the positioning plate 10 when it is fixed, and through the telescopic effect of the positioning plate 10, when the injection molded part is large, the extension plate 102 is ejected by the second spring 15, so that the length of the positioning plate 10 is extended, so that the positioning plate 10 in the device can be positioned. The range of the position is increased, thereby further improving the practicality of the device, and the outer wall side of a pair of extension plates 102 and the outer wall side of the square plate 101 and the tip of the cutting knife 5 are all in the same plane, so that the square plate 101 and the extension plate 102 have a positioning function, and the top of the outer wall of the workbench 1 is rotatably connected to the first double-threaded rod 11 through the first square plate; the outer wall of the first double-threaded rod 11 is threadedly connected to a pair of clamping plates 12 symmetrical about the center line of the workbench 1; the outer wall bottom ends of the pair of clamping plates 12 are slidably connected to the top of the outer wall of the workbench 1, and the pair of clamping plates 12 are rotated by the first double-threaded rod 11. The double threaded rod 11 is threadedly connected, so that the rotation of the first double threaded rod 11 can cause a pair of clamping plates 12 to move toward the center or both sides of the workbench 1 at the same time, so that when the injection molded part is placed on the workbench 1 for cutting, the first double threaded rod 11 can be rotated to cause the pair of clamping plates 12 to clamp and fix the injection molded part, so that the pair of clamping plates 12 are fixed and squeezed and fixed by the positioning plate 10, so that the injection molded part is more stable and not easy to shift when being cut, so that the injection molded part after cutting can be more beautiful and not easy to have defects, and a right-angled trapezoidal groove 18 is opened through the top of the outer wall of the workbench 1; the top of the inclined surface of the right-angled trapezoidal groove 18 is in the same plane as one side of the outer wall of the positioning plate 10;A closed shell 19 is hingedly connected at the edge of one side of the top of the outer wall of the workbench 1, and one side of the outer wall of the closed shell 19 is open. The closed shell 19 is located above the right-angled trapezoidal groove 18. The right-angled trapezoidal groove 18 is opened at the top of the outer wall of the workbench 1, so that the burrs of the injection molded part will fall into the right-angled trapezoidal groove 18 after being cut off, so that the cut burrs are collected in a centralized manner, and the top of the inclined surface of the right-angled trapezoidal groove 18 is in the same plane with one side of the outer wall of the positioning plate 10, so that before the burrs of the injection molded part are cut off, the burrs that need to be cut off will be above the inclined surface of the right-angled trapezoidal groove 18, so that the burrs that need to be cut off are in a suspended state, so that the burrs of the injection molded part are easier to be cut off, and after cutting, they will fall onto the inclined surface of the right-angled trapezoidal groove 18, thereby sliding along the inclined surface into the right-angled trapezoidal groove 18 and being collected, so that the cut burrs are easier to be collected, and the closed shell 19 is hingedly connected at the edge of one side of the top of the outer wall of the workbench 1 , and one side of the outer wall of the closed shell 19 is open, and the closed shell 19 is located above the right-angled trapezoidal groove 18, so that the closed shell 19 will block the upper and side surfaces of the right-angled trapezoidal groove 18, so that the external force of the external environment is not easy to blow or drive the cut burrs to move, so that the cut burrs and the waste generated during the cutting will not fly around, so that not only the cut burrs of the injection molded parts and the waste generated during the cutting are collected, but also the cut burrs of the injection molded parts and the waste generated during the cutting can be prevented from flying around and polluting the environment, so that not only the waste generated during the cutting of the injection molded parts pollutes the environment, but also the staff is more convenient to clean up, and a pair of sliding grooves 16 are opened through the top of the outer wall of the square plate 101, and the pair of sliding grooves 16 are respectively connected to the pair of first through grooves 13; the outer side walls of a pair of moving blocks 14 are respectively slidably connected to the inner side walls of the pair of first through grooves 13 and the sliding grooves 16, and the moving blocks 14 are in an inverted T shape;A second double-threaded rod 17 is rotatably connected to the center of the top of the outer wall of the square plate 101 through the second square plate, and the two ends of the outer wall of the second double-threaded rod 17 respectively penetrate a pair of moving blocks 14, and the second double-threaded rod 17 is threadedly connected to the pair of moving blocks 14. By rotating the second double-threaded rod 17, since the second double-threaded rod 17 is threadedly connected to the pair of moving blocks 14, the rotation of the second double-threaded rod 17 causes the pair of moving blocks 14 to move toward the center or both sides of the square plate 101 at the same time, so that the movement of the pair of moving blocks 14 will drive the pair of second springs 15 and the pair of extension plates 102 to move, so that the length of the extension plates 102 outside the square plate 101 can be adjusted, so that the device can be adjusted by adjusting the position of the moving block 14. The length of the extension plate 102 outside the square plate 101 is reduced, so that the positioning range of the extension plate 102 and the square plate 101 is further increased, so that the device can position injection molded parts with longer or shorter lengths, and when the second spring 15 is used for a long time, the elastic force of the second spring 15 will be reduced, so that the positioning range of the positioning plate 10 is reduced. By adjusting the second double-threaded rod 17, the extendable range of the extension plate 102 on the positioning plate 10 can be increased, so that when the elastic force of the second spring 15 is reduced, the extension range of the extension plate 102 can be increased by adjusting the second double-threaded rod 17, so that the extension range of the extension plate 102 is within a stable range, thereby improving the service life of the positioning plate 10. ;
