Description

Technical Field

[0001] The utility model relates to the field of material mixing devices for component injection molds, in particular to a material mixing device for component injection molds. Background Art

[0002] The development and application of electrical appliances have made people's lives richer and more convenient, and the application of plastic parts in the electrical industry has enabled electrical appliances to have sufficient quality while significantly reducing their costs, making the prices of electrical appliances more affordable, allowing a large number of electrical appliances that were very expensive in the past to enter thousands of households. The production and manufacturing of plastic parts mostly adopts an injection molding process in which molten injection molding materials are injected into an injection mold and then cooled to form. The molten injection molding material needs to be mixed in a solid state first, and then transported by a screw conveyor device, and converted into a molten injection molding material during the conveying process. It is first transported into the injection mold. When mixing solid materials, the traditional mold mixing device pours the raw materials directly into the mixing drum for stirring, resulting in the inability to screen out large particles in the raw materials. In the subsequent process of converting the raw materials into molten injection molding materials, these large particles are difficult to be converted, resulting in uneven density of the injection molding material and poor quality of subsequent plastic products.

[0003] In the prior art, a patent document with application number CN202223428949.0 reviewed and published by the State Intellectual Property Office of China discloses a utility model patent named a mixing device for injection molds of household appliance parts, a feed hopper and a crushing mechanism, and a feed hopper is installed at the upper left end of the mixing box. The crushing mechanism, a filter screen and a first heater are installed in the feed hopper from top to bottom. The crushing mechanism first crushes the various materials entering the mixing box, and then filters them through the filter screen to screen the smaller injection molding raw material particles, and at the same time can effectively filter out impurities in the injection molding raw material particles.

[0004] However, in the prior art, after the raw materials are poured into the feed hopper of the mixing device used for the injection mold of home appliance parts, some raw materials with larger particles will sink on the filter screen arranged at the bottom of the feed funnel, and thus cannot be crushed by the crushing wheel. When the filter screen is cleaned, these large particles of raw materials will be wasted. Utility Model Content

When the driving gear 10 is meshed with the driven gear 9, the driven gear 9 rotates in the opposite direction to the driving gear 10, thereby driving the filter drum 3 to rotate in the opposite direction to the crushing wheel 6, thereby realizing the rotation of the crushing wheel 6 and the reverse rotation of the filter drum 3.

The motor 14 is turned on to drive the wheel shaft 7 to rotate through the transmission shaft of the motor 14, and the wheel shaft 7 drives the crushing wheel 6 to rotate. At the same time, the rotation of the wheel shaft 7 drives the gear shaft 11 to rotate in the same direction through the belt transmission mechanism 12, and the gear shaft 11 drives the driving gear 10 to rotate. Under the meshing of the driving gear 10 and the passive gear 9, the passive gear 9 is rotated. The rotation in the opposite direction to the driving gear 10 drives the filter cartridge 3 to rotate in the opposite direction to the crushing wheel 6, thereby realizing the rotation of the crushing wheel 6 and the reverse rotation of the filter cartridge 3; when feeding into the filter cartridge 3, the sealing screw 5 is screwed out from the screw hole on the surface of the filter cartridge 3, and then the feed cover plate 4 is screwed out from the feed port of the filter cartridge 3, and the raw material can be added into the filter cartridge 3 from the feed port of the filter cartridge 3. After adding, the feed cover plate 4 is screwed back to its original position and the sealing screw 5 is screwed into the screw hole of the filter cartridge 3, thereby closing the feed port of the filter cartridge 3 to prevent the raw material from leaking out of the feed port.
