AI Technical Summary

Technical Problem

The discharge conveying device of the existing injection molding machine is far away from the product demolding position, which causes the product to easily deform during the fall, and the traditional buffer parts are prone to wear, have a short service life, which affects the product quality.

Method used

An injection molding machine discharge conveying device including a base, an output mechanism and a buffer mechanism is designed. The output mechanism realizes close-die release of the product by lifting the lifting frame, and uses gas buffering to reduce the impact force when the product falls through the inflation box and the inflation cylinder in the buffering mechanism.

Benefits of technology

It effectively reduces the impact force and impact force of the product during the transmission process, improves the stability of the output process of injection molded parts, extends the service life of the buffer structure, and ensures product quality.

Abstract

The invention discloses a discharging conveying device of an injection molding machine, relates to the field of discharging conveying devices of injection molding machines, and solves the problem that the discharging conveying device of the existing injection molding machine has a large impact force when in use, which affects the product quality. The invention comprises a base, an output mechanism and a buffer mechanism, wherein the output mechanism comprises a lifting frame and an output frame, and the buffer mechanism comprises an air charging box and an air charging cylinder. A plurality of first blowing holes are provided in the lifting frame and the output frame. The invention links the lifting frame to lift and lower during the moving injection molding process of the movable mold through the output mechanism, so that the lifting frame moves up and approaches the product during demoulding, and links the air charging box to inflate and pressurize through the buffer mechanism, so that the gas is blown out through the first blowing holes on the inner wall of the lifting frame, so as to reduce the impact force of the product during the falling process, and transports the product to the output frame for output when the lifting frame moves downward, and at the same time links the air charging cylinder to pressurize and inflate, so that the first blowing holes in the output frame blow air, so as to reduce the impact force when the product moves to the output frame.
