Description

Technical Field

[0001] The utility model relates to the technical field of material blanking protection for injection molding machines, in particular to a material blanking protection device for injection molding machines. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity.

[0003] In the prior art, after the injection molding machine forms a plastic product, a robot is usually used to grab the plastic product and place it on a conveyor belt for the next process. However, when the robot grabs the plastic product and drops it on the conveyor belt, since the conveyor belt is in a forward conveying state, the plastic product is prone to jump on the conveyor belt when it falls and contacts the conveyor belt, causing the plastic product to jump outside the conveyor belt. Therefore, an injection molding machine unloading protection device is needed to solve the above problem. Utility Model Content
