Description

Technical Field

[0001] The present invention relates to the technical field of injection molding equipment, and in particular to an injection molding device for a highly dispersive bamboo charcoal polyester fiber composite material. Background Art

[0002] Highly dispersive bamboo charcoal polyester fiber is a composite material in which bamboo charcoal nanoparticles are evenly distributed in a polyester substrate through a special process. It is made by adding nanoscale bamboo charcoal powder and melt-spinning. It has functions such as odor adsorption and antibacterial. By injection molding on the bamboo charcoal polyester fiber, a composite workpiece is formed, which has good practicality, aesthetics and environmental protection at the same time. Therefore, it is favored in the fields of automobiles, furniture, etc.

[0003] In the processing of existing highly dispersive bamboo charcoal polyester fiber composite materials, the highly dispersive bamboo charcoal polyester fiber needs to be first woven into a fabric, then cut and installed on a mold, and preforming and injection molding operations are carried out successively. The entire process involves multiple independent workstations, and frequent material transfer and equipment switching between processes not only consume a large amount of time, but also easily cause the material to be affected by the external environment during the transfer process, resulting in temperature fluctuations, pollution and other conditions, seriously affecting product quality and production efficiency; existing injection molding devices are mostly single-mode structures and cannot carry out preforming and final injection molding work simultaneously. After each preforming is completed, operations such as mold switching and material reloading need to be waited for, and the equipment is in an idle or low-efficiency operating state for a long time, resulting in waste of resources. The fabric needs to be manually positioned and installed by workers during installation, and the production efficiency is low. Summary of the Invention
