Technical Field

[0001] The invention relates to the technical field of molds, and in particular to an intelligent plastic broom hair-planting hole multi-angle core-pulling mold. Background Art

[0002] Plastic brooms are processed using injection molds. After the injection molding is completed, it is necessary to drill holes for implanting hair on the broom, and then implant the plastic filaments into the holes. This results in low processing efficiency and uneven distribution of the holes, affecting product quality.

[0003] Prior art CN206416451U discloses a multi-angle core-pulling mold for hair-planting holes of a plastic broom, comprising a fixed mold and a movable mold, wherein the movable mold comprises a lower composite plate, a core, and a mold foot arranged between the lower composite plate and the core, and the core is provided with a core-pulling mechanism for core-pulling hair-planting holes on the end face of the plastic broom, the core-pulling mechanism comprises a first side pull-out block, and a second side pull-out block and a third side pull-out block distributed on both sides of the first side pull-out block, the first side pull-out block, the second side pull-out block, and the third side pull-out block are arranged on the core and can slide along the core, the first side pull-out block, the second side pull-out block, and the third side pull-out block are all connected with a plurality of cores for forming hair-planting holes on the end face of the plastic broom, and the core is provided with a fixed mold that fits the end face of the plastic broom. A positioning plate is provided with a plurality of positioning holes for cores to pass through. After the fixed mold and the movable mold are closed, the fixed mold and the movable mold form a cavity under the action of the cavity plate and the core, and hot-melt plastic is injected into the cavity, so that the hot-melt plastic forms the shape of a plastic broom in the cavity after cooling. Among them, a plurality of cores pass through the positioning plate, and the ends of a plurality of cores protrude from the positioning plate and are located in the cavity. The first side pull-out block, the second side pull-out block, and the third side pull-out block are driven by an external hydraulic cylinder to slide on the core, so that a plurality of cores are pulled out from the end face of the plastic broom, thereby forming a plurality of implantation holes on the end face of the plastic broom. After that, the plastic broom is ejected out of the cavity under the action of the ejector pin, and the production of the plastic broom is completed.

[0004] The above-mentioned device uses a core to form a number of bristle holes on the end face of the plastic broom after injection molding is completed, but the core angle is fixed. However, in actual applications, plastic brooms for different purposes have diverse requirements for the angle of the bristles; for example, a broom used for floor cleaning may require the bristles to maintain a certain inclination angle with the ground to improve cleaning efficiency; while a broom used for wall or ceiling cleaning may require the bristles to be nearly perpendicular to the cleaned surface to ensure the cleaning effect. Even on the same broom, it may be necessary to achieve a gradual change or specific distribution of the bristle angle according to different usage scenarios or design requirements. The non-adjustable core angle in the above-mentioned device cannot meet the processing requirements of different brooms. Summary of the invention
