Description

Technical Field

[0002] An injection molding machine, also known as an injection molding machine or injection machine, is the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting plastics using plastic molding molds. Currently, optical drive cover plates require injection molding machines with multiple mold cavities. This produces multiple optical drive cover plate products and parts such as sprues. After injection molding and release from the mold, the parts can be dropped directly into a storage area, or a robotic gripper can be used to pull the parts from the mold and then transfer them to the storage area. Due to the sprues, existing suction jigs cannot simultaneously pull multiple optical drive cover plates and sprues. After release from the mold, the sprues can only be dropped into the storage area inside the injection molding machine. To remove the parts, workers must reach into the storage area to clean them. Due to the high injection temperatures of injection molding machines, this poses a safety hazard to workers. Summary of the Invention
