Description

Technical Field

[0001] The utility model relates to a feeding system of an injection molding machine used for producing lampshades. Background Art

[0002] Lampshades are common products in the injection molding field, usually made by mixing multiple raw materials, such as polycarbonate and light diffusers. Existing injection molding machine feeding systems mostly use a single storage mode, which is difficult to meet the production requirements of precise mixing of multiple materials. The main problems are as follows:

[0003] Uneven feeding: Traditional storage systems have poor processing effects on raw materials with poor fluidity, such as powder materials, and are prone to blockage or insufficient feeding, affecting the uniformity and quality of the final product.

[0004] Insufficient mixing precision: The existing system lacks efficient mixing equipment, making it difficult to ensure the uniformity and proportion control of raw materials. This is especially evident in the production of products such as lampshades that require high optical uniformity.

[0005] Large measurement errors: Traditional measurement methods mostly rely on manual or simple electronic measurements, which are prone to errors and cannot meet high-precision production requirements.

[0006] Low conveying efficiency: During the conveying stage, materials are prone to separation or loss due to vibration or impact, further affecting the stability of the product.

[0007] Therefore, developing an injection molding machine feeding system specifically for lampshade production that can efficiently complete the precise storage, uniform mixing, precise metering and stable transportation of multiple materials is the key to solving the above problems.
