Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine injection, and more specifically, to a novel nozzle anti-spray protection cover. Background Art

[0002] With the rapid development of the new energy vehicle industry in recent years, plastics, as one of the most common component raw materials in new energy materials, are being widely used in the automotive manufacturing industry. At present, the main clamping mechanisms used in plastic injection machines include toggle type and two-platen type. Due to the simple and compact structure, large mold opening stroke and no usage restrictions, the two-platen injection molding machine is being widely used in the current plastic manufacturing process. As an important branch of the two-platen machine, the multi-color machine (multi-shot table) is also widely used in actual production.

[0003] For existing multi-shot injection molding machines, the number of materials or colors of the injection molding machine can generally be increased by adding a right-angle shooting table (sub-shooting table). Due to the existence of the right-angle shooting table, when processing personnel open door and window components to take out production materials or perform maintenance, the molten plastic in the right-angle shooting table may be accidentally sprayed out, resulting in safety accidents. Therefore, the right-angle shooting table needs to take certain safety measures to prevent the occurrence of accidental spraying of molten plastic.

[0004] The Chinese patent announcement number is CN217414709U, and the announcement date is September 13, 2022. The name of the application is an injection molding nozzle device for an injection molding machine. The application discloses an injection molding nozzle device for an injection molding machine, including a nozzle body, an exhaust mechanism and a flow-stopping mechanism. The nozzle body includes an injection barrel and a nozzle connected to each other. The injection barrel is installed on the injection molding machine, and the nozzle is used to eject the colloid; the exhaust mechanism is used to discharge the bubbles inside the nozzle; the exhaust mechanism includes a mounting plate, a stirring shaft, a stirring impeller and three exhaust pipes. The mounting plate is arranged between the injection barrel and the nozzle, one end of the stirring shaft is rotatably connected to the mounting plate, and the other end of the stirring shaft is tightly connected to the stirring impeller. The three exhaust pipes are all fixedly connected to the nozzle, and the three exhaust pipes are all connected to the inside of the nozzle; the flow-stopping mechanism is arranged in the injection barrel, and is used to prevent the colloid inside the injection barrel from flowing back to the injection molding machine. The flow-stopping mechanism in the above structure can only prevent the colloid from flowing back into the injection molding machine, but cannot prevent the plastic from being sprayed out of the nozzle.
