As shown in fig. 1-5, an injection structure of a plastic mold injection molding machine comprises a feeding cylinder 110, an injection cylinder 120 and a screw 130, wherein the screw 130 is transversely arranged in the injection cylinder 120, and the feeding cylinder 110 is vertically arranged on the injection cylinder 120. The material is heated and flows into the charging barrel 110, and then falls into the screw 130 in the injection barrel 120, and the screw 130 rotates to push the material to move toward the outlet of the injection barrel 120.

The injection molding barrel 120 is communicated with a connecting pipe 140, the lower end of the feeding barrel 110 is inserted into the connecting pipe 140 and is detachably connected with the connecting pipe 140, a blocking piece 210 and a blocking ring 220 are arranged in the lower end of the feeding barrel 110, the blocking piece 210 is circular, and an opening of the blocking ring 220 is circular. The baffle sheet 210 is located above the baffle ring 220, a height difference exists between the baffle sheet 210 and the baffle ring 220, so that a gap allowing the raw material to flow through is left between the baffle sheet 210 and the baffle ring 220, the baffle sheet 210 covers an opening of the baffle ring 220 in the vertical direction, and the baffle sheet 210 is connected with the baffle ring 220 through a connecting rod 230. The material falls from the top of the feed cylinder 110, the middle material falls onto the middle baffle 210, the surrounding material falls onto the surrounding baffle ring 220, and the material falls onto the screw 130 from the middle opening of the baffle ring 220. The baffle plate 210 and the baffle ring 220 provide a supporting force for the falling of the raw material, and the raw material falls onto the screw 130 from the opening of the baffle ring 220, so that the falling height of the raw material is reduced, the impact force of the raw material on the screw 130 is reduced, the screw 130 is effectively protected, and the service life of the screw is prolonged.

An annular connecting sleeve 310 is arranged between the connecting pipe 140 and the feeding cylinder 110, the annular connecting sleeve 310 is provided with a plugging groove 320 downwards, the lower end of the feeding cylinder 110 is inserted into the plugging groove 320 of the annular connecting sleeve 310, the outer side of the annular connecting sleeve 310 is connected with the connecting pipe 140 through threads, and the baffle ring 220 is connected with the upper end of the annular connecting sleeve 310. The annular connection sleeve 310 is screwed with the connection pipe 140, which makes the baffle 210 and the baffle ring 220 worn seriously after a long time use, and the baffle 210 and the baffle ring 220 can be replaced. The charging barrel 110 is inserted into the insertion groove 320 to be connected with the annular connecting sleeve 310, so that the charging barrel 110 can be easily separated from the annular connecting sleeve 310.

The annular connecting sleeve 310 is in threaded connection with the connecting pipe 140. The lateral wall of the insertion groove 320 is provided with a slide strip 410 along the vertical direction, the lower end of the feeding cylinder 110 is provided with a slide groove 420 along the vertical direction, when the lower end of the feeding cylinder 110 is inserted into the insertion groove 320, the slide strip 410 is inserted into the slide groove 420, and the feeding cylinder 110 and the annular connecting sleeve 310 are limited to rotate relatively. Thus, the charging barrel 110 is driven to rotate, so that the charging barrel 110 drives the annular connecting sleeve 310 to be in threaded connection with the connecting barrel.

The sidewall of the retainer ring 220 is inclined downward to form a funnel shape of the retainer ring 220. This makes it easier for the material falling onto the retainer ring 220 to fall onto the screw 130 along the opening in the middle of the retainer ring 220.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
