Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a low-residue injection molding device comprises a charging barrel 1, a heating plate 5 and a feeding port 8, wherein a rotating shaft 2 is rotatably arranged inside the charging barrel 1, the lower end of the rotating shaft 2 is fixedly connected with an output shaft of a motor 16 positioned at the lower end of the charging barrel 1, two processing threaded blades 4 are symmetrically welded on the outer wall of the upper end of the rotating shaft 2, the outer wall of the lower end of the rotating shaft 2 is rotatably connected with a fixed seat 15 and a pair of extrusion threaded blades 3 which are slidably arranged between the two processing threaded blades 4, the lower end of the extrusion threaded blade 3 is fixedly connected with the fixed seat 15, a chute 6 is arranged on the outer wall of the charging barrel 1, a slide block 12 is slidably arranged on the outer wall of the charging barrel 1, the mounting hole has been seted up in the up end of slider 12 runs through, and the inside of mounting hole is equipped with cylinder 13, the left end of cylinder 13 slides and sets up in spout 6, locating hole 14 that the telescopic link that corresponds with cylinder 13 is seted up to fixing base 15's outer wall, a pair of gag lever post 10 of 7 fixedly connected with of a pair of riser of feed cylinder 1's outer wall, gag lever post 10's outer wall sliding connection slider 12, the annular has been seted up to fixing base 15's outer wall, and the inside rotation of annular is equipped with connecting plate 11, connecting plate 11's upper end fixed connection slider 12, the outer wall fixedly connected with shield 9 of riser 7, shield 9's bottom fixed connection feed cylinder 1.

The working principle is as follows: when the machine works, the motor 16 drives the extruding thread blade 3 and the processing thread blade 4 to rotate, and plastics are stirred and extruded through the processing thread blade 4; when residues are removed, the motor 16 drives the extruding thread blades 3 and the processing thread blades 4 to rotate, so that the positioning holes 14 are aligned with the telescopic rods of the air cylinders 13, the telescopic rods of the air cylinders 13 are inserted into the positioning holes 14 to circumferentially fix the extruding thread blades 3, then the motor 16 drives the processing thread blades 4 to rotate, so that the extruding thread blades 3 slide and move upwards among the processing thread blades 4, and residual plastics among the processing thread blades 4 are extruded and discharged through an extrusion opening of the charging barrel 1; after removal, the motor 16 drives the processing thread blade 4 to rotate reversely, and the extrusion thread blade 3 moves downwards to reset because the extrusion thread blade 3 cannot rotate; when the sliding block is removed and reset, the left end of the air cylinder 13 and the sliding block 12 respectively slide up and down in the sliding groove 6 and the limiting rod 10; the dust cover 9 prevents dust and the like from polluting the inside of the injection molding device; the positioning hole 14 and the air cylinder 13 are ensured not to be displaced in the vertical direction by the connecting plate 11.
