A feeding nozzle in an online molding device for carbon fiber composite materials

Abstract

The invention relates to a feeding spray nozzle in an online carbon fiber composite die-pressing device, which belongs to the field of machinery, and aims to solve the problems that the existing spray nozzle adopting horizontal injection mostly wastes materials and has a poor injection effect, and as production automation is difficult to realize, the productivity of carbon fiber composite products can be reduced. The feeding spray nozzle comprises a spray nozzle body horizontally and fixedly arranged at the front end of a cylinder, a discharge outlet is arranged at the front end of the cylinder, a cavity is arranged inside the spray nozzle body, one end of the cavity is connected with the discharge outlet, a vertical downward spout is arranged in the lower side surface of the spray nozzle body and connected with the other end of the cavity, and a sealing cover device for opening and closing the spout is arranged on the spray nozzle body. By virtue of the structure, a carbon fiber composite can be easily and effectively injected into a die, the spout can be freely opened and closed, the production automation of whole online die pressing can be realized, and thus the productivity and the quality of the carbon fiber composite products are greatly improved.

Description

technical field [0001] The invention belongs to the field of machinery and relates to an online molding device, in particular to a feeding nozzle in the online molding device for carbon fiber composite materials. Background technique [0002] Carbon fiber composite materials have been highly concerned by people because of their excellent strength and corrosion resistance. Carbon fiber composite products are generally formed by injection molding, molding and pultrusion on-line molding equipment. In existing online molding devices, horizontal injection molding machines are generally used to inject material into the mold, and then carry out molding and pultrusion. Since the feeding nozzle on the horizontal injection molding machine is installed horizontally, the nozzle is located at one end of the nozzle, so the nozzle is horizontally opposite. The mold is injecting material, and the carbon fiber composite material is in a thick state at this time, and the material flows out fr...

Problems solved by technology

With this structure, the traditional horizontal injection is changed to vertical injection, so that the placement position of the mold can also be changed according to the change of the feeding direction. After the molded product is sent out, the mold can be re-filled, and the production automation can be easily realized. Capping The design of the device not only solves the problem of random dripping of the material under its own weight when there is no need for material injection, but also overcomes the problem of plugging the spout due to the hardening of the remaining material, so as to ensure effective material injection and improve product quality.
