Description

Technical Field

[0001] This utility model relates to the field of plastic jewelry production technology, and more specifically, to a plastic jewelry injection molding mechanism. Background Technology

[0002] Plastic ornaments are decorative items made primarily of synthetic or semi-synthetic polymers (i.e., plastics) through processes such as injection molding, compression molding, carving, and dyeing. Their core value lies in using industrialized production methods to transform inexpensive basic materials into fashionable items of various shapes and colors, thus popularizing decorative art.

[0003] In the processing of plastic jewelry, injection molding equipment is a key device for completing injection molding. Operators typically place the mold below the injection port and inject molten plastic into the mold cavity through the equipment to form the product. However, existing injection molding mechanisms of this type have a common drawback: their structural design often does not adequately consider the problem of cleaning up residue at the injection port. Because some plastic easily cools and solidifies at the injection port during the injection process, if it is not removed in a timely and effective manner, it will cause blockage at the outlet, thereby affecting the continuity of subsequent injection molding operations and product quality, causing inconvenience to actual production. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a plastic jewelry injection molding mechanism that can automatically clean the outlet of the injection molding equipment, preventing material residue from causing blockages and facilitating subsequent normal use, thereby solving the problems mentioned in the background technology.

[0005] (II) Technical Solution To achieve the aforementioned advantages of automatically cleaning the outlet of the injection molding equipment, preventing material residue from causing blockages, and thus facilitating normal subsequent use, the specific technical solution adopted by this utility model is as follows: A plastic jewelry injection molding mechanism includes a machine body. A mounting plate is fixedly connected to one side of the top surface of the machine body, and a connecting box is fixedly connected to one side of the mounting plate. A fixing plate is fixedly connected inside the connecting box, and a first motor is fixedly mounted on one side of the fixing plate. A screw is fixedly connected to the output end of the first motor, and a moving block is threaded onto the screw. A connecting block is fixedly connected to the bottom surface of the moving block through a connecting groove opened on the bottom surface of the connecting box, and a fixing block is fixedly connected to the bottom end of the connecting block. A second motor is mounted on one side of the fixing block, and a rotating rod is fixedly connected to the output end of the second motor. A frame is provided on the outer side of the rotating rod, and a cleaning frame is fixedly connected to one side of the frame. A second cleaning brush is fixedly connected to one side of the inner wall of the cleaning frame, and a first cleaning brush is provided on the inner side of the cleaning frame.

[0006] Furthermore, a limiting block is fixedly connected to one side of the top and bottom surfaces of the rotating rod, and one end of the limiting block extends into the interior of the limiting groove opened on the lower top surface and upper bottom surface of the frame. The limiting block and the limiting groove are rectangular structures, and one end of the limiting block extends into the interior of the limiting groove and slides in connection with the limiting groove.

[0007] Furthermore, there are multiple first cleaning brushes, and the multiple first cleaning brushes are evenly distributed around the inside of the cleaning frame. The first cleaning brushes and the second cleaning brushes are matched with the cleaning frame.

[0008] Furthermore, a rod is fixedly connected to the first cleaning brush through the cleaning frame, and a first spring is sleeved on the outer surface of the rod between the first cleaning brush and the cleaning frame.

[0009] Furthermore, the connecting box has a limiting rod inside the moving block, and the moving block is slidably connected to the limiting rod.

[0010] Furthermore, a second spring is installed between the rotating rod and the frame.

[0011] Furthermore, the connecting block and the connecting groove are rectangular structures, and the connecting block slides through the connecting groove and is slidably connected to the connecting groove.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a plastic jewelry injection molding mechanism, which has the following beneficial effects: (1) In this utility model, the first motor in the connecting box is started, which drives the screw to rotate; under the cooperation of the limiting rod, the moving block generates axial displacement along the screw, and the moving block drives the connecting block connected to it, so that the latter moves smoothly along the connecting groove at the bottom of the connecting box, thereby pushing the second motor to move as a whole. When the cleaning frame moves to the outside of the injection outlet of the machine body, the second motor is started to drive the rotating rod to rotate. Through the cooperation of the frame, the limiting block and the limiting groove, the rotational motion is transmitted to the cleaning frame. The first cleaning brush and the second cleaning brush built into the cleaning frame then automatically clean the solidified material remaining around the outlet, effectively avoiding the blockage problem caused by the accumulation of material, thereby ensuring the smooth flow of the injection molding equipment outlet and the normal operation of subsequent work, which is conducive to improving its work continuity.

[0013] (2) In this utility model, the first cleaning brush is elastically limited by the cooperation of the insert rod and the first spring, ensuring that it always keeps in close contact with the outlet surface of the machine body during the working process, thereby effectively improving the cleaning effect. In addition, when the frame moves to contact the outlet, the rotating rod continues to advance, driving the limiting block to slide along the limiting groove on the frame and compressing the second spring set inside the frame. This mechanism can absorb the impact force generated when the cleaning frame contacts the outlet, avoiding rigid collisions that could damage the outlet, thus protecting the equipment structure and improving the operational stability and safety of the cleaning process.

The outlet is cleaned; and a fixing block 11 is fixedly connected to the bottom end of the connecting block 9. A second motor 10 is installed on one side surface of the fixing block 11, and a rotating rod 19 is fixedly connected to the output end of the second motor 10. A frame 13 is provided on the outside of the rotating rod 19, and a cleaning frame 12 is fixedly connected to one side surface of the frame 13. A second cleaning brush 21 is fixedly connected to one side of the inner wall of the cleaning frame 12, and a first cleaning brush 14 is provided on the inner side of the cleaning frame 12. When the second motor 10 is started, the second motor 10 drives the rotating rod 19 to rotate. With the use of the frame 13, the limiting block 18 and the limiting groove 17, the cleaning frame 12 can be driven to rotate. Through the use of the first cleaning brush 14 and the second cleaning brush 21 in the cleaning frame 12, the residual material on the outlet can be automatically cleaned to prevent the material from remaining on the outlet and causing blockage.

[0020] Please see Figure 1 , Figure 2 and Figure 4 A limiting block 18 is fixedly connected to one side of the top and bottom surfaces of the rotating rod 19, and one end of the limiting block 18 extends into the interior of the limiting groove 17 opened on the lower top surface and upper bottom surface of the frame 13. The limiting block 18 and the limiting groove 17 are rectangular structures, and one end of the limiting block 18 extends into the interior of the limiting groove 17 and slides in connection with the limiting groove 17. When the second motor 10 is started, the second motor 10 drives the rotating rod 19 to rotate. With the use of the frame 13, the limiting block 18 and the limiting groove 17, the cleaning frame 12 can be driven to rotate.

[0021] Please see Figure 2 and Figure 3Multiple first cleaning brushes 14 are provided, and the multiple first cleaning brushes 14 are evenly distributed around the inside of the cleaning frame 12. The first cleaning brushes 14 and the second cleaning brushes 21 are matched with the cleaning frame 12. By using the first cleaning brushes 14 and the second cleaning brushes 21, the outlet on one side surface of the machine body 1 can be cleaned to prevent material residue on the outlet and ensure its normal subsequent use.

[0022] Please see Figure 2 and Figure 3 A rod 15 is fixedly connected to the first cleaning brush 14 through the cleaning frame 12. The rod 15 is movably connected to the cleaning frame 12. A first spring 16 is sleeved on the outer surface of the rod 15 between the first cleaning brush 14 and the cleaning frame 12.

[0027] Working Principle: First, the material is added to the machine body 1. The machine body 1 then performs injection molding. After molding, the first motor 8 in the connecting box 3 is activated. The first motor 8 drives the screw 5 to rotate. Combined with the use of the limiting rod 4, the moving block 7 on the screw 5 is limited, allowing it to move along the screw 5. Simultaneously, the moving block 7 moves the connecting block 9 in the connecting groove 6 on the bottom surface of the connecting box 3. The moving block 9 also moves the fixed block 11, causing the second motor 10 to move. When the cleaning frame 12 moves to the outside of the outlet on the machine body 1, the second motor 10 is activated. The second motor 10 drives the rotating rod 19 to rotate. In conjunction with the frame 13, the limiting block 18, and the limiting groove 17, the cleaning frame 12 can be rotated. Through the use of the first cleaning brush 14 and the second cleaning brush 21 in the cleaning frame 12, the residual material on the outlet can be automatically cleaned to prevent the material residue from causing blockage on the outlet, thus ensuring its normal subsequent use. The insertion rod 15 and the first spring 16 can limit the first cleaning brush 14 so that the first cleaning brush 14 can always be in contact with the outlet on one side surface of the machine body 1, thereby improving the cleaning effect of the outlet.
