Description

Technical Field

[0001] The utility model relates to the technical field of display molding dies, in particular to a molding die for producing a display rear shell and a base. Background Art

[0002] During the production of monitor back covers and bases, double-cavity injection molds are typically used, allowing the back cover and base to be molded simultaneously during the same injection cycle. However, during the injection molding process, especially when producing large plastic products such as monitor back covers and bases, a large amount of odor often occurs during the mold cooling process. This odor primarily originates from volatile organic compounds (VOCs) and decomposition products of plastic materials and their additives at high temperatures. These odors not only negatively impact the air quality in the workshop and potentially endanger the health of operators, but also affect the environment of other production workstations, reducing overall work comfort.

[0003] Traditional methods rely on the workshop's overall ventilation and air purification systems to deal with these odors. However, these methods are generally inefficient and difficult to effectively control at the source of odors. In addition, the workshop's overall air handling equipment may not be able to address specific issues in the mold operation area, causing odors to spread throughout the production environment and affect production at other workstations.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 In an embodiment of the present invention, a molding die for producing a display back cover and a base comprises an injection molding table 1, a double-cavity injection molding die, a partition mechanism and a ventilation and deodorization mechanism.

[0022] In the specific implementation process, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the upper surface of the injection molding table 1 is provided with two symmetrically arranged sliding cavities 4, and the injection molding table 1 is connected to a double-cavity injection mold for producing the back shell and the base of the display, and the double-cavity injection mold includes a lower mold 2 and an upper mold 3. The upper surface of the injection molding table 1 is fixedly connected with the lower mold 2, and the upper mold 3 is installed on the lower mold 2. The injection molding table 1 is connected with an injection molding table 1 separation mechanism, and the separation mechanism includes a servo motor 16, a screw rod 17, a slide rod 18, a slider 19, an L-shaped push block 5 and a half cover body 6. A servo motor 16 is installed on one side of the injection molding table 1, and the output end of the servo motor 16 passes through the side of the injection molding table 1 and is fixedly connected to the screw rod 17 through a coupling. The other end of the screw rod 17 is fixedly connected to the inner side surface of the injection molding table 1, and the thread directions of the two ends of the screw rod 17 are opposite. The screw rod 17 is threaded with two symmetrically arranged sliders 19, and two slide rods 1 arranged parallel to the screw rod 17 are fixedly connected inside the injection molding table 1. 8. The slider 19 is slidably mounted on the two sliding rods 18. The upper surface of the slider 19 is fixedly connected with an L-row pushing block 5. The L-row pushing block 5 passes through the adjacent sliding cavity 4 and is fixedly connected with a half-cover body 6. The half-cover body 6 is slidably connected to the upper surface of the injection molding table 1. The injection molding table 1 is connected with a ventilation and deodorization mechanism. The ventilation and deodorization mechanism includes a fan 11, an exhaust hose 12, a purification box 13, activated carbon 10, an air pipe 14 and an exhaust pipe 20. A fan 11 is installed on one side of the injection molding table 1. The inlet of the fan 11 is fixedly connected to the side of one of the half-cover bodies 6 through the exhaust hose 12. Two symmetrically arranged air inlets 7 are provided on the side of the other half-cover body 6. A purification box 13 is also installed on one side of the injection molding table 1. Activated carbon 10 is provided in the purification box 13. The outlet of the fan 11 is fixedly connected to one side of the purification box 13 through the air pipe 14. The other side of the purification box 13 is fixedly connected with the exhaust pipe 20.

[0023] It should be noted that: when the rear shell and base of the display are produced by injection molding using a double-cavity injection mold composed of a lower mold 2 and an upper mold 3, the rotation of the servo motor 16 can drive the rotation of the screw 17. The rotation of the screw 17 causes the two sliders 19 to slide horizontally along the slide rod 18 and approach each other. The movement of the slider 19 pushes the horizontal sliding of the half-cover body 6 through the L-row pushing block 5, so that the two half-cover bodies 6 fit together, and the double-cavity injection mold is isolated in the two half-cover bodies 6 (at this time, the sliding cavity 4 is not within the range of the half-cover body 6), and the fan 11 exhausts air through the exhaust hose 12, so that the isolated environment formed by the two half-cover bodies 6 generates negative pressure, so that the outside air is blown into the two half-covers from the air inlet 7. The air flows into the isolated environment formed by the body 6, and the odor generated during the cooling process of the mold is taken away by the air flow. The air flow is passed into the purification box 13 through the air supply pipe 14, and the air flow is adsorbed and purified by the activated carbon 10 in the purification box 13. The air flow is then discharged through the exhaust pipe 20. Therefore, during the cooling process of the mold, the odor can be processed at the source as soon as it is generated, thereby preventing the odor from spreading to other areas of the workshop and protecting the health of the operators. Moreover, the flow of air can effectively improve the cooling efficiency of the mold, thereby improving the production efficiency. After cooling is completed, the servo motor 16 is started to reverse, the two half-cover bodies 6 are removed, and the mold is opened and closed without affecting the normal opening and closing and injection operation of the double-cavity injection mold.

[0024] refer to Figure 3 and Figure 5 As shown, the purification box 13 is connected to a flipping mechanism, which includes a motor 21, a rotating shaft 22 and a flipping rod 23.

A plurality of evenly distributed flipping rods 23 are fixedly connected to the side of the rotating shaft 22.

[0025] It should be noted that during use, the rotation of the motor 21 can drive the rotating shaft 22 to rotate, and the rotation of the rotating shaft 22 drives the turning rod 23 to rotate and turn the activated carbon 10. By turning the activated carbon 10 regularly, the utilization rate of the activated carbon 10 is effectively improved.

[0026] refer to Figure 2 As shown, a cleaning port is provided on one side of the purification box 13 , and a matching sealing door 15 is installed in the cleaning port. The cleaning port and the sealing door 15 facilitate the replacement of the activated carbon 10 in the purification box 13 .
