Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic parts production, in particular to a mold for producing dehumidifier plastic parts. Background Art
[0002] Dehumidifiers are widely used in civil and industrial fields. Their working principle is to draw moist air into the machine through a fan, condense the water molecules in the air into water droplets through a heat exchanger, and then discharge the treated dry air out of the machine, thus maintaining the appropriate indoor humidity.
[0003] In the production process of dehumidifiers, plastic parts are important components. Their quality and production efficiency directly affect the performance and cost of the entire machine. Their production requires the use of molds. However, the molten plastic in the existing mold is connected to the molten plastic in the pipeline. The cooling process will cause the temperature of the molten plastic in the pipeline to drop, causing it to solidify in the pipeline and cause pipeline blockage.
[0004] A Chinese patent discloses a plastic mold for producing plastic parts (authorization publication number CN219563970U). This patented technology allows pressurized molten plastic to be passed into a feed pipe. Once the pressurized molten plastic enters the feed pipe, it depresses an isolation plug, which then enters the mold. Once the isolation plug enters the mold, the molten plastic enters the mold through a feed hole. During cooling, the pressure of the molten plastic in the feed pipe is reduced. Once the pressure is reduced, a return spring pulls the isolation plug at the lower end of the return guide rod upward, thereby isolating the molten plastic in the mold from the molten plastic in the pipe and preventing the molten plastic in the pipe from solidifying.
[0005] However, it has certain disadvantages: the molten plastic is discharged into the mold through the feed hole on the surface of the isolation plug. Although it can prevent the molten plastic from remaining on the inner wall of the pipe, some molten plastic will still remain in the feed hole. The molten plastic in the feed hole is difficult to clean. Over time, the feed hole will also be blocked, thereby affecting the molten plastic from entering the mold. Utility Model Content

[0027] The telescopic cylinder 8 is preferably a pneumatic cylinder. After it extends, it can drive the demolding ring 10 to rise, thereby ejecting the formed dehumidifier plastic part molding cavity 3, and then completing the automatic demolding of the dehumidifier plastic part molding cavity 3.
[0028] In Figure 2 and Figure 4 : A counterweight 11 is installed inside the feed main pipe 4. A scraping sleeve 12 is installed on the outer surface of the counterweight 11. The outer surface of the scraping sleeve 12 is movably fitted to the inner surface of the feed main pipe 4. Two sliding rods 13 are symmetrically and movably penetrated through the counterweight 11.
