A direct-connected all-electric injection plasticizing driving system

Abstract

The invention discloses a direct-connected full-electric injection plasticizing and driving system, which comprises a rectangular injection bench, a linear guide rail, an annular moment motor, a ribbed slab, a connection disc, a ball bearing lead screw nut, a bearing, a bearing sleeve, a mold movement sleeve support bench, a mold movement sleeve, a chute, a projection, a servo motor, a screw, a machine cylinder and a feed inlet, two rectangular through holes are opened at side edge of the rectangular injection bench, a linear guide rail is fixed on each through hole, a rotor of the annular moment motor is connected to the screw, the projection is arranged at end of the ball bearing lead screw nut, and the projection is capable of sliding in the chute. Compared with the full-electric injection plasticizing driving system in prior art, member rotation shafts capable of performing revolution motion is positioned on same line, vibration due to machine unbalance can be reduced, the injection motor is removed from the injection bench simultaneously, injection bench vibration due to rotation of the injection motor can be avoided, screw wearing due to vibration can be reduced, injection bench weight is reduced, and injection speed is increased.

Description

technical field [0001] The invention relates to a novel injection plasticizing drive system, which belongs to the field of injection molding machine equipment. Background technique [0002] With the concept of environmental protection, energy saving and high efficiency promoting the rapid transformation of the industrial structure in the machinery industry, injection molding equipment is developing rapidly in the direction of high speed and high efficiency, precision energy saving, low noise and high automation. The current all-electric injection molding machine has abandoned the traditional hydraulic pressure Drive the injection molding machine to have defects such as oil pressure control loss, pipe loss, valve resistance and other flow losses, and oil pump volumetric efficiency, friction loss, etc., and has high precision, high production efficiency, energy saving, clean and environmentally friendly, wide speed control range, and responsiveness. Good advantages, has become...

AI Technical Summary

Problems solved by technology

The injection and plasticization driving system of the traditional all-electric injection molding machine is composed of servo motor, synchronous belt, synchronous wheel, coupling, etc. The servo motor is distributed on the side of the injection table, which causes the quality of the entire injection table to be misaligned. Such a machine Misalignment will aggravate the mechanical vibration of the system. Since the distance between the screw and the barrel is very small, the vibration is extremely easy to cause contact wear between the screw and the barrel, thereby affecting the precision, injection performance and injection speed of the injection molding machine
