Detailed Description
The utility model will be described in further detail with reference to the following figures and specific examples, without limiting the scope of the utility model.
As shown in fig. 1 to 4, in the hot nozzle assembly for a plastic mold cigarette holder of the present embodiment, the plastic mold is provided with a flow channel, and includes a sealing hanging block 1, a glue injection hot nozzle 2, and a hot nozzle sleeve 3 adapted to the glue injection hot nozzle 2;
the sealing hanging block 1 is provided with a first hot nozzle mounting hole; one end of the hot nozzle sleeve 3 is sleeved in the first hot nozzle mounting hole; the hot nozzle sleeve 3 is provided with a second hot nozzle mounting hole, the end face of one end of the hot nozzle sleeve 3 is provided with a first inverted structure 31, and the first inverted structure 31 extends out of the first hot nozzle mounting hole; one end of the glue injection hot nozzle 2 is sleeved in the second hot nozzle mounting hole; when the plastic mold is used, the sealing hanging block 1 covers a runner of the plastic mold in a sealing manner, so that the first inverted buckle structure 31 extends into the runner.
When the hot nozzle sleeve 3 moves upwards, the first reversing structure 31 is clamped with the stub bar, so that the stub bar is pulled to move upwards, and the stub bar is broken and separated from the formed product; after the stub bar is pulled out, the stub bar can be separated from the first reversing structure 31 of the hot nozzle sleeve 3 by enabling the sealing hanging block 1 and the hot nozzle sleeve 3 to move relatively, so that the stub bar can be removed.
This embodiment realizes the mouth of a river purpose of breaking through setting up first back-off structure 31 on hot mouth cover 3 to save mouth of a river crochet hook structure, makeed the product row position interval reduce greatly, do benefit to the cave position number that increases in one set of mould, do benefit to the size that reduces whole mould structure simultaneously, and then greatly reduced processing cost.
Based on the above embodiment, further, the outer surface of the first undercut structure 31 is uniformly distributed with a microstructure (not shown) of one or more combinations of ribs, corrugated grooves, spiral grooves and teeth. Due to the arrangement, the contact area between the first reversing structure 31 and the stub bar is increased, the first reversing structure 31 is guaranteed to be in buckling connection with the stub bar when the stub bar is separated from a product, the stub bar is not prone to being pulled out, and the structure is more reliable; meanwhile, different microstructures are arranged to adapt to the molding of different material products, so that the reliable realization of the water gap snapping is ensured.
Based on the above embodiment, further, the first reversing structure 31 is integrally formed on the hot nozzle sleeve 3. So set up for first back-off structure 31 is more firm, reliable.
Based on the above embodiment, further, the first reverse-buckling structure 31 is a frustum snap ring adapted to the aperture of the second hot nozzle mounting hole. So set up, through frustum buckle and the stub bar joint after the shaping to realize the purpose that the mouth of a river broke.
Based on the above embodiment, a first sealing ring (not shown) is further disposed between the hot nozzle sleeve 3 and the glue injection hot nozzle 2. Specifically, this first sealing washer setting is close to the one end of first back-off structure 31 at the hot mouth mounting hole of second, so sets up, avoids the hot melt adhesive to spill over to between the inner wall of hot mouth cover 3 and the outer wall of the hot mouth 2 of injecting glue.
Based on the above embodiment, a second sealing ring (not shown) is further disposed between the hot plug sleeve 3 and the sealing hanging block 1. Specifically, this second sealing washer sets up the one end that is close to first back-off structure 31 at first hot mouth mounting hole, so sets up, avoids the hot melt adhesive to spill over to between the outer wall of hot mouth cover 3 and the inner wall of sealed hanging piece 1.
Based on the above embodiment, further, one end of the first hot nozzle mounting hole is arranged in a tapered shape, and one end of the hot nozzle sleeve 3 is arranged in a tapered shape; the outer conical surface of one end part of the hot nozzle sleeve 3 is matched with the conical surface of one end part of the first hot nozzle mounting hole. So set up for sealed hanging piece 1 more closely with the cooperation of hot mouth cover 3, improves the leakproofness.
The above description is only a preferred embodiment of the present invention, and all equivalent changes or modifications of the structure, characteristics and principles described in the present patent application are included in the protection scope of the present patent application.
