Nozzle anti-blocking device for injection molding machine and method of use thereof

Abstract

The invention discloses an injection molding machine nozzle anti-blocking device and a use method thereof and belongs to the field of injection molding machines. For the injection molding machine nozzle anti-blocking device, an anti-blocking mechanism automatically performs continuous disturbance on a nozzle by utilizing flowing of a material, and the probability of occurrence of the nozzle blocking problem can be lowered by at least 10 percent. Specifically, a first gear and a second gear perform the double stirring effect on the material, and the caking probability of the material can be lowered by at least 5 percent; every time that the second gear rotate with one circle, the larger end of the second gear is utilized to poke a smooth rod, the smooth rod drives a tamping rod to perform disturbance on the nozzle at one time, and the material blockage at the nozzle can be effectively prevented; in the process that an elastic backward pulling rod pulls back the tamping rod, the tampingrod performs disturbance on the nozzle at one time again, and continuous disturbance is realized; and when flowing of the material is insufficient to drive the anti-blocking mechanism to automaticallyperform continuous disturbance on the nozzle, a motor drives a first rotary shaft to rotate, and continuous disturbance on the nozzle by the anti-blocking mechanism is realized.

Description

technical field [0001] The invention relates to the field of injection molding machines, and more specifically, to an anti-blocking device for nozzles of injection molding machines and a method for using the same. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Divided into vertical, horizontal, all-electric. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and make it inject and fill the mold cavity. The working principle of the injection molding machine is similar to that of a syringe for injection. It uses the thrust of the screw (or plunger) to push the plasticized plastic The process of injecting plastic in a molten state (that is, a viscous fluid state) into a closed mold cavity, and obtaining a fin...
