[0016] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the embodiments of the present invention.

[0017] See also Figure 1-Figure 7 The present invention provides an injection mold for producing a wet wipes barrel cover, comprising a bottom mold 1 and a top mold 2, the bottom mold 1 and the top mold 2 are slidably connected to each other through positioning rods 3 arranged at four corners, both sides of the top mold 2 are fixedly connected with a connecting frame 5, a heat dissipation component and a cleaning component are movably arranged on the connecting frame 5, the heat dissipation component is located above the cleaning component, and the cleaning component cleans the middle concave part of the bottom mold 1; The end of the connecting frame 5 is fixedly connected to a bracket 8, and a collection component is fixedly installed on the bracket 8. The collection component is arranged on one side between the bottom mold 1 and the top mold 2. The collection component includes a storage box 12 and a protective plate 11. The top of the storage box 12 is fixedly connected to a frame 18, and the frame 18 is connected to one end of the protective plate 11. The protective plate 11 is inclined. Connecting arms 17 are connected to both sides of the middle of the protective plate 11. A soft board 16 is fixedly installed between the two connecting arms 17, and a soft leather layer is covered on the surface of the soft board 16. By arranging connecting frames 5 on both sides of the top mold 2, a group of storage boxes 12 are connected at the tail of the connecting frame 5 through the bracket 8. The storage box 12 is between the top mold 2 and the bottom mold 1, which is convenient for demolding the mold after injection molding of the two and entering the storage box 12, so as to achieve the effect of rapid collection and improve the overall operation efficiency.

[0018] By arranging the protective plate 11 and the flexible plate 16 between the storage box 12 and the bracket 8, when the mold after injection molding is collected, the injection molded parts first contact the surfaces of the protective plate 11 and the flexible plate 16, thereby greatly reducing the noise generated by damage and collision of the surface of the injection molded parts, and having a certain protective effect on the ears of nearby workers.

[0019] The heat dissipation component includes a side panel 4 and a rotating rod 19. The top end of the side panel 4 and the middle part of the rotating rod 19 are mutually connected. The rotating rod 19 is arranged in the middle part of the connecting frame 5. The outer end of the connecting frame 5 is fixedly connected with a motor 13. The output end of the motor 13 and the end of the rotating rod 19 are mutually connected. The rotating rod 19 drives the side panel 4 to flip.

[0020] Through holes 6 are evenly opened on both sides of the surface of the side plate 4, and a positioning plate is fixedly installed in the middle of the two through holes 6. A fan 7 is fixedly connected to the middle of the positioning plate, and one end of the positioning plate is fixedly connected to the driving machine. The output end of the driving machine is connected to the central axis of the fan 7. When the top mold 2 and the bottom mold 1 are separated, the injection molded part between the two can be blown by the fan 7, so as to achieve the effect of air cooling, which is convenient for rapid molding of the injection molded part and reduces the temperature of the entire injection molded part. Further, the driving machine is started (the driving machine is a micro motor or a small motor), and the driving machine drives the fan 7 to rotate, thereby generating wind force, and the wind force is used to blow the surface of the injection molded part. As can be seen from the figure, the fan 7 is arranged in the side plate 4, and the number is two, that is, the two side plates 4 are four groups of fans 7, which can make both sides of the injection molded part cool, greatly improving the cooling effect of the overall injection molded part.

[0021] The cleaning component includes two rotating plates 9 installed on both sides of the bottom of the side plate 4. A second motor 14 is arranged outside the rotating plate 9. The output end of the second motor 14 is connected to the rotating plate 9 through a rod body, and the second motor 14 drives the rotating plate 9 to rotate.

[0022] A polished rod and a cleaning roller 10 are arranged at the bottom end of the rotating plate 9, and the cleaning roller 10 is inserted on the polished rod. The polished rod and the cleaning roller 10 are horizontally installed between the two rotating plates 9. A motor three 15 is fixedly connected to one side of the bottom of the rotating plate 9, and the output end of the motor three 15 is connected to the polished rod. A plurality of rubber convex strips are fixedly installed on the surface of the cleaning roller 10. First, the motor one 13 is started to drive the side plate 4 to adjust the angle, and the motor two 14 is started to complete the angle adjustment of the rotating plate 9. Finally, by starting the motor three 14, the distance between the top mold 2 and the bottom mold 1 is reduced at the same time, so that the cleaning roller 10 can fit the position of the recessed part in the middle of the bottom mold 1. As the motor three 15 is started, the cleaning roller 10 can be driven to rotate. At this time, the cleaning roller 10 can realize high-speed rotation and cleaning inside the recessed part, so that the neatness of other injection molded parts can be guaranteed during the injection molding process in the later stage.

[0023] A protrusion 20 is fixedly connected to the middle of the bottom end of the top mold 2. The structure of the protrusion 20 corresponds to the concave part in the middle of the bottom mold 1. Positioning holes 22 are provided at the four corners of the top mold 2. The four positioning holes 22 are connected with four positioning rods 3. By setting the positioning holes 22 and interlacing with the positioning rods 3, it is effectively ensured that the bottom mold 1 and the top mold 2 are always on the same horizontal plane. When the top mold 2 moves, the protrusion 20 in the middle of the top mold 22 can directly contact the concave part in the middle of the bottom mold 1, so that the injection molded part is effectively formed. Before molding, a plurality of feed holes are opened on the edge of the bottom mold 1, and the injection liquid can be transported to the inside of the recessed part along the feed holes before use, so as to achieve the effect of subsequent injection molding.

[0024] A lifting plate 21 is provided on the inner side of the protrusion 20, and the surface of the lifting plate 21 is flush with the surface of the protrusion 20. The injection molded parts can be pushed by the lifting plate 21. The lifting plate 21 can be squeezed by the two convex strips on the top of the top mold 2 (as can be seen from the figure, no further details are given on this), so that the lifting plate 21 can achieve a small extension movement inside the protrusion 20, and with the extrusion injection molding between the top mold 2 and the bottom mold 1, the injection molded parts can be attached to the surface of the protrusion 20. Therefore, at this time, the lifting plate 21 is pushed to allow the injection molded parts attached to the protrusion 20 to complete the rapid falling-off process, so that the injection molded parts can directly enter the interior of the storage box 12 for later collection.
