Nozzle special for injection molding of airplane seat plastic product

Abstract

The invention belongs to the technical field of plastic processing equipment, and discloses a special injection nozzle for injection molding of aircraft seat plastic products, which comprises an injection molding pipe barrel, an injection molding screw rod is movably sleeved in the injection molding pipe barrel, and one end of the injection molding screw rod is fixedly connected with a screw rod tip. Through the arrangement of the mounting sleeve, the fan blades and the auger, in the injection molding process, the auger rotates along with rotation of the fan blades, the inner wall of an injection hole can be repeatedly scraped and cleaned, a plastic solution can be guided in a one-way mode, the backflow resistance of the plastic solution is increased, backflow of the plastic solution is avoided, and meanwhile, the service life of the plastic solution is prolonged. In the pressure maintaining process, the auger is gradually inserted into the injection nozzle hole formed in one end of the injection nozzle body, scraping and cleaning of the inner wall of the injection nozzle hole are achieved, plastic solution residues are avoided, meanwhile, after injection molding is completed, automatic reset can be achieved under the springback of the reset spring, secondary scraping is conducted on the injection hole, and plastic solution residues are further avoided.

Description

Technical field [0001] The present invention belongs to the technical field of plastic processing equipment, specifically an aircraft seat plastic product injection molding special nozzle. Background [0002] Common aircraft seats are generally made of plastic products, and plastic products in the process of processing and molding will need to go through multiple processing molding, and injection molding engineering is the top priority, therefore, injection molding quality often plays a key role in the quality of aircraft seats, and injection molding machines are also known as injection molding machines or injection machines. It is the main molding equipment for thermoplastics or thermosetting plastics to make various shapes of plastic products using plastic molding molds, divided into vertical, horizontal, all-electric, injection molding function can heat plastics, apply high pressure to molten plastics, so that they shoot out and fill the mold cavity. It needs to melt the soli...

AI Technical Summary

Problems solved by technology

[0003] In the current commonly used injection molding equipment, generally after the injection is completed, there will still be molten raw materials in the nozzle, especially when the viscosity of the raw materials is relatively low, the phenomenon is more serious

Moreover, the molten plastic stuck at the injection hole of the nozzle is easy to block the injection hole, and it is troublesome to deal with after the blockage, which will affect the normal development and production.
