Injection molding nozzle capable of preventing instantaneous impact and cleaning blockage

Abstract

The invention relates to the technical field of plastic injection molding, and discloses an injection molding nozzle capable of preventing instantaneous impact and cleaning blockage. The injection molding nozzle comprises a liquid storage cavity, wherein the lower end of the liquid storage cavity is fixedly connected with a buffer box, the lower end of the buffer box is fixedly connected with a buffer plate, the two sides of the bottom of the liquid storage cavity are fixedly connected with buffer springs, a movable plate is fixedly connected to the side face of the liquid storage cavity, a metal feeler lever is fixedly connected to the surface of the movable plate, a liquid outlet pipe is fixedly connected to the interior of the buffer box, an air inlet pipe is movably wound around the surface of the liquid outlet pipe, and an air pump is fixedly connected to one end of the air inlet pipe. According to the injection molding nozzle, the buffer box is fixedly connected to the lower end of the liquid storage cavity, the buffer plate is fixedly connected to the lower end of the buffer box, and the buffer springs are fixedly connected between the buffer plate and the liquid storage cavity, so that the effects of preventing high-temperature and high-pressure plastic liquid from being in direct contact with the nozzle and protecting the nozzle from being impacted by instantaneous impact force are achieved.

Description

technical field [0001] The invention relates to the technical field of plastic injection molding, in particular to an injection nozzle that prevents instantaneous impact and can clear blockage. Background technique [0002] During plastic injection molding, because the personnel did not clean up the plastic residue inside the nozzle in time, the nozzle will be blocked. When the current nozzle is blocked, workers need to disassemble it and clean the inside, which increases the difficulty of work for workers. The efficiency of production is reduced, and the high-temperature and high-pressure solution directly contacts the nozzle, and the instantaneous impact generated by the solution is easy to cause damage to the nozzle. [0003] In order to solve the above problems, the inventor provides an injection molding nozzle that prevents instantaneous impact and can clear clogging. A buffer tank is fixedly connected to the lower end of the liquid storage chamber, and a buffer plate i...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an injection nozzle that prevents instantaneous impact and can clear clogging. It can relieve the instantaneous impact of the solution, prevent the nozzle from being damaged, and can automatically clean the clogged nozzle, and make full use of the solution. Heat, more energy-saving and environmental protection, no need to disassemble and then clean, improve the production efficiency, solve the need for workers to dismantle it and then clean the inside when the nozzle is blocked, which increases the difficulty of work for workers and reduces production The efficiency, and the high-temperature and high-pressure solution is directly in contact with the nozzle, and the instantaneous impact generated by the solution is likely to cause damage to the nozzle
