[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a hot nozzle molding die, including a main body 1, the main body 1 is a main component of the hot nozzle molding die, and a hot nozzle is arranged inside to heat the hot melt plastic and inject it into the mold core 2 for extrusion molding. The lower end of the main body 1 is internally slidably connected with a connecting component, and the connecting component can position the mold core 2 so that it is placed in the installation position. A slide groove 7 is opened on the lower side of the main body 1, and the slide groove 7 can make the clamping block 3 slide up so that the mold core 2 can be clamped and fixed inside the lower end of the main body 1 with the main body 1. The internal thread of the slide groove 7 is connected with a bolt 10, and the bolt 10 can clamp the clamping block 3 on the slide. Inside the lower end of the groove 7, the external thread of the bolt 10 is connected with a clamping block 3, which can position and fix the mold core 2 so that the mold core 2 can be quickly disassembled and installed. The outside of the clamping block 3 is slidably connected to the inside of the lower end of the slide groove 7, and the side end of the clamping block 3 is provided with a square groove 11. The square groove 11 can clamp the clamping block 8 and pull the clamping block 8 upward, so that the mold core 2 is clamped and remains stable without shaking. The side end of the clamping block 3 is slidably connected with the mold core 2, and the upper end of the mold core 2 is connected to the hot nozzle so that the plastic can be extruded and formed to complete the injection molding operation. The outside of the mold core 2 is slidably connected to the inside of the lower end of the main body 1, and the main body 1 supports and fixes the mold core 2.

[0032] Reference Figure 1-Figure 3The inside of the mold core 2 is elastically connected to the clamping block 8 through a spring 15. The clamping block 8 is pulled upward by the square groove 11, so that the mold core 2 is subjected to an upward pulling force, which can reduce the shaking of the mold core 2 and increase the stability during injection molding. The outside of the clamping block 8 is slidably connected to the inside of the square groove 11, and one end of the spring 15 is fixedly connected to the inside of the mold core 2. The spring 15 is squeezed to fix the clamping block 8 inside the square groove 11, and the other end of the spring 15 is fixedly connected to the side of the clamping block 8. The spring 15 is squeezed by the mold core 2 to keep the clamping block 8 squeezed. The side end of the clamping block 8 is fixedly connected to a U-shaped rod 12, and the clamping block can be pulled by pulling the U-shaped rod 12. 8 can slide out of the square groove 11 to release the limit, which is convenient for disassembly and quick replacement of the worn core 2. The middle outer part of the U-shaped rod 12 is slidably connected with a sliding block 14. The sliding block 14 is U-shaped and can be squeezed so that the U-shaped rod 12 can slide out of the core 2. The outer parts of the U-shaped rod 12 and the sliding block 14 are slidably connected to the two ends of the core 2. The U-shaped rod 12 and the sliding block 14 maintain horizontal sliding within a fixed distance. The upper end of the sliding block 14 is slidably connected with a magnet 13. The upper part of the magnet 13 is in contact with the inside of the core 2. The adsorption of the magnet 13 can fix the sliding block 14 in the core 2 to keep the position fixed and will not slide out and be squeezed and damaged.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The connection assembly includes an I-shaped block 4, which can be positioned so that the mold core 2 can only slide horizontally. The outer sliding portion of the I-shaped block 4 is connected to the bottom of the main body 1, and the I-shaped block 4 can slide in from the left and right ends of the main body 1. The front end of the I-shaped block 4 is fixedly connected with a stopper 5, which can stop the mold core 2 so that it can stop at the installation position and no longer slide. This makes it convenient for the bolt 10 to be rotated into the lower end of the main body 1 without manual fixing, etc., which increases the ease of operation. The side end of the stopper 5 is connected to the front and rear side ends of the mold core 2 The front part of the I-shaped block 4 is slidably provided with a stop block 9, which can stop the I-shaped block 4 and fix it inside the main body 1, and the stop block 9 is L-shaped, and has a grinding pattern at the lower end to facilitate the sliding of the stop block 9 so that the I-shaped block 4 can slide in, and the side end of the stop block 9 is elastically connected to the lower end of the main body 1 through a spring 26, and the spring 26 can squeeze the stop block 9 to keep it in a fixed position, one end of the spring 26 is fixedly connected to the lower end of the main body 1, and the other end of the spring 26 is fixedly connected to the side end of the stop block 9.

[0034] Working principle: by grinding the lower end of the stop block 9 at one end of the slide, the stop block 9 can slide in the direction of the spring 2 6, and then the I-block 4 can be slid into the lower end of the main body 1, and then the stop block 9 is released, so that the spring 2 6 squeezes the stop block 9 to slide back to its original position, so that the I-block 4 is clamped and fixed by the main body 1 and the stop block 9, and then the mold core 2 is slid horizontally from the other end of the I-block 4 so that the lower part of the I-block 4 slides into the upper end of the mold core 2, and then slides horizontally until the side end of the mold core 2 contacts the stop block 5, at which time the mold core 2 stops at the installation position, and then the bolt 10 is turned to rotate its upper end into the lower end of the main body 1 so that the upper end of the card block 3 slides into the inside of the slide groove 7, so that the card block 3 pulls the clamping block 8 upward, and the clamping block 8 pulls the mold core 2 to keep it stable and will not shake, then the sliding stop block 9 can be pressed by the spring 2 6, and then the I-shaped block 4 can be slid out, and the stop block 9 can be released to make it slide back under the pressure of the spring 2 6. When the mold core 2 is worn, the sliding block 14 can be slid out, and the sliding block 14 drives the U-shaped rod 12 to slide to both ends, and the U-shaped rod 12 drives the clamping block 8 to slide into the interior of the mold core 2 to squeeze the spring 15, and then the mold core 2 can be disassembled, and the mold core 2 that has been maintained or replaced can be slid back to its original position, and the sliding block 14 can be released. At this time, the spring 15 squeezes the clamping block 8 to slide into the interior of the square groove 11, and the U-shaped rod 12 slides into the interior of both ends of the mold core 2, so that the sliding block 14 slides back to its original position, and the magnet 13 adsorbs the mold core 2 so that the sliding block 14 is fixed and will not slide out.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
