Description

Technical Field

[0001] The utility model relates to the technical field related to the production of injection molded parts, in particular to a raw material crushing and constant temperature mixing device for the production of injection molded parts. Background Art

[0002] During the mixing process of raw materials, the raw materials need to be heated at a constant temperature to ensure the pre-heating treatment of the raw materials, so as to facilitate the hot melting of the raw materials when entering the injection molding machine. However, the commonly used mixing device is not convenient for constant temperature heating and mixing of the raw materials, which is prone to uneven mixing of the raw materials. The uneven mixing of the raw materials leads to poor color fusion of the raw materials during hot melting, which in turn leads to color spots on the injection molded parts. In addition, the large temperature difference makes it easy for the raw materials to be heated unevenly during heating treatment, thereby affecting the subsequent injection molding effect.

[0003] After searching, it is found that a Chinese patent document discloses a raw material crushing and constant temperature mixing device for injection molding production [Announcement No.: CN216267280U]. This raw material crushing and constant temperature mixing device for injection molding production includes a hollow barrel, a fixed cover is fixedly installed on the top of the hollow barrel, and a feed hopper is fixedly connected to the inner wall of one side of the fixed cover, a driving motor is fixedly installed on the top of the fixed cover, and a rotating column is fixedly connected to the rotating shaft of the driving motor, and a propeller for moving the raw material upward is fixedly connected to the bottom end of the rotating column.

[0004] When the device disclosed in the patent is in use, the staff can use hot water to keep the hollow barrel warm, and then cooperate with the raw material mixing work. However, in this way, the raw materials on the inner side of the hollow barrel cannot directly contact the heat source, resulting in poor heat transfer effect, which may affect the subsequent injection molding effect.

[0022] The conveying mechanism 6 includes a water pump 61 fixed on the surface of the constant temperature water tank 5 and a water distribution pipe 64 connected to both sides of the stirring rod 3. The output end of the water pump 61 is connected to a water supply pipe 62. One end of the water supply pipe 62 is connected to the inner cavity of the constant temperature water tank 5. The other end of the water supply pipe 62 is rotatably connected to a connector 63. The connector 63 is arranged at one end of the stirring rod 3. The surface of the water distribution pipe 64 is connected to a connecting pipe 65. The other end of the connecting pipe 65 is connected to a return pipe 66. The return pipe 66 is rotatably connected to the stirring rod 3.
