Abstract

The invention provides a plasticizing device and an injection molding machine. The plasticizing device is used for melting a plastic material and comprises a charging barrel with an inner cavity extending in a preset direction; a screw which is mounted in the charging barrel and extends in the preset direction; a rotating shaft which is arranged at one end of the screw and is in transmission connection with the screw so as to drive the screw to rotate through the rotating shaft; an adjusting seat mounted on the rotating shaft, wherein a through hole is formed in the adjusting seat, the screw is arranged in the through hole in a penetrating manner and is in clearance fit with the inner wall of the through hole, a plurality of first threaded holes are formed in the adjusting seat, the multiple first threaded holes are formed in the circumferential direction of the through hole at intervals, and all the first threaded holes extend to the inner wall of the through hole; and a plurality of adjusting pieces provided with external threads, wherein the multiple adjusting pieces are matched with the multiple first threaded holes in a one-to-one correspondence mode through the threads, and the end portions, located in the through hole, of the multiple adjusting pieces abut against the screw. The plasticizing device solves the problem that a screw of a plasticizing device in the prior art is not convenient to adjust.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a plasticizing device and an injection molding machine. Background technique [0002] The plasticizing device is a key component of the injection molding machine, and its function is to melt the plastic material in the barrel through the rotation of the screw. [0003] In the prior art, due to the existence of processing and assembly errors, the screw of the plasticizing device is often misaligned with the barrel, that is to say, when the plasticizing device is used, the screw is often not in the center of the barrel. In this way, it will not only increase the friction between the barrel and the screw to damage the screw, but also seriously affect the plasticizing effect. After the screw rod in the prior art is installed, it is difficult to adjust the position of the screw rod. Contents of the invention [0004] The main purpose of the present invention is to provide...
