For a better understanding of the objects, structure and function of the present invention, a side-entry hot nozzle system of the present invention will be described in further detail with reference to the accompanying drawings.
As shown in figures 1 and 2, the side-glue-feeding heat nozzle system of the utility model comprises a heat nozzle body 1, wherein a flow channel 2 is arranged in the heat nozzle body 1, and the flow channel 2 is used for plastic particles in a molten state to flow. The flow passage 2 is communicated with a nozzle core 3, and plastic particles are discharged from the hot nozzle body 1 through the nozzle core 3.
In order to realize the installation of the nozzle core 3, the hot nozzle body 1 is detachably connected with a pressing plate 4, the nozzle core 3 is pressed on the hot nozzle body 1 by the pressing plate 4, and the nozzle core 3 is communicated with the flow passage 2. Thereby separating the core 3 from the hot nozzle body 1 by removing the pressure plate 4. And because body 1 and clamp plate 4 are divided into two parts to heat, chew core 3 and can follow the lower extreme and directly install, the fixed die plate need not to set up and dodge the hole. In order to fix the pressure plate 4, a bolt connection or an electromagnetic adsorption is generally adopted.
Referring to fig. 3, a tapered nozzle 31 is formed on the side of the mouthpiece 3. In order to make the chewing core 3 and the runner 2 smoothly communicate, a connecting inclined plane 32 is formed at one end of the chewing core 3, an inlet 33 communicated with the inner cavity of the chewing core 3 is arranged on the connecting inclined plane 32, the connecting inclined plane 32 is jointed with the hot chewing body 1, and the inlet 33 is communicated with the runner 2.
And a splicing surface 41 is formed on the edge of the pressure plate 4, and the splicing surface 41 is jointed with the end surface of the hot nozzle body 1, so that the pressure plate 4 and the hot nozzle body 1 are spliced into a whole.
Since the nozzle 31 projects from the side of the hot nozzle body 1, the hot nozzle body 1 is formed with the upper groove 11, the presser plate 4 is formed with the lower groove 42, and both sides of the nozzle core 3 are fitted in the upper groove 11 and the lower groove 42, respectively. Furthermore, the upper groove 11 and the lower groove 42 each include a half hole 5, the two half holes 5 are combined to form a through hole, and the nozzle 31 extends from the hot nozzle body 1 through the through hole. A sealing rubber ring 34 is sleeved between the spray head 31 and the via hole, and the sealing rubber ring 34 ensures internal and external sealing.
As shown in fig. 4 and 5, in order to supply a plurality of cores 3 to the runner 2, the runner 2 comprises a primary runner 21, two primary runners 22 are connected in parallel to the primary runner 21, and two secondary runners 23 are connected in parallel to each primary runner 22. And the number of the flow passages 2 at each stage can be correspondingly adjusted according to the number of the nozzle cores 3. The end of the secondary flow channel 23 is formed with a tertiary flow channel 24 extending to both sides of the hot nozzle body 1, and the tertiary flow channel 24 is obliquely arranged and communicated with the inlet 33 of the nozzle core 3.
As shown in fig. 6 and 7, in order to provide the flow paths 2, a processing channel 12 extending to the surface of the heat nozzle body 1 is formed at one end of each flow path 2, and the flow paths 2 in the heat nozzle body 1 are formed by processing through the processing channel 12. A plug 6 is in interference fit in the processing channel 12, and the plug 6 seals the processing channel 12 to prevent the leakage of the flow channel 2.
