[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 The utility model provides an embodiment: an injection mold for a welcome lamp holder that is easy to dissipate heat, including a fixed block 1, which can position the entire device, and the right part of the fixed block 1 is fixedly connected to a fixed shaft 2, which is restricted and kept fixed by the fixed block 1, so that the upper mold 4 is kept fixed, and the right part of the fixed shaft 2 is fixedly connected to the upper mold 4, and a hole is provided in the middle of the upper mold 4 to allow plastic to enter the middle of the upper mold 4 and the lower mold 3 for extrusion molding, and a telescopic rod 6 is fixedly connected to the middle of the fixed block 1, and the telescopic rod 6 can drive the lower mold 3 to slide to the position of injection molding and unloading, and the right part of the telescopic rod 6 is fixedly connected to the lower mold 3, and a square groove is provided on the side end of the lower mold 3 to fix the mold core for injection molding, and the side end of the lower mold 3 is internally slidably connected to the outside of the fixed shaft 2, and the fixed shaft 2 can limit the lower mold 3 to only slide in a straight line to maintain stability.

[0032] Reference Figure 2-Figure 3The side end of the lower mold 3 is elastically connected with a U-shaped block 7 through a spring 11. The U-shaped block 7 can fix the tube groove 10 and the connecting groove 8 relative to the lower mold 3. One end of the spring 11 is fixedly connected to the inside of the side end of the lower mold 3, and the other end of the spring 11 is fixedly connected to the outside of the side end of the U-shaped block 7. The spring 11 is squeezed to fix the U-shaped block 7 in a sliding state to maintain stability. The side end of the U-shaped block 7 is slidably connected with a ramp block 12. The ramp block 12 is squeezed to make the U-shaped blocks 7 at both ends slide into the lower mold 3. This makes it convenient for the connecting groove 8 and the tube groove 10 and the tube groove 2 9 to slide out for replacement and maintenance. The side of the ramp block 12 is fixedly connected with a connecting rod 15 The connecting rod 15 can drive the inclined plane blocks 12 at the upper and lower ends to slide into the U-shaped block 7. The connecting rod 15 and the outer parts of the inclined plane block 12 are slidably connected to the side end of the lower mold 3. The lower mold 3 limits the connecting rod 15 and the inclined plane block 12 to slide horizontally only within a fixed distance. The outer parts of the U-shaped block 7 are slidably connected with a cooling component and a connecting groove 8 respectively. The connecting groove 8 can connect a hose 5 and a pipe groove 10 and a pipe groove 2 9, so that the coolant can enter the lower mold 3 for cooling. The outer part of the connecting groove 8 is slidably connected to the side end of the lower mold 3. The outer part of the connecting groove 8 is fixedly connected with a hose 5. The hose 5 can transport the coolant to the middle of the pipe groove 10 and the pipe groove 2 9 to cool the mold core.

[0033] Reference Figure 2 and Figure 4 The cooling component includes a tube groove 10. The circular groove between the tube groove 10 and the tube groove 2 9 allows the coolant to flow in and out, so that the mold core can be cooled. The outside of the tube groove 10 is slidably connected to the middle interior of the lower mold 3. The inside of the tube groove 10 is fixedly connected with a magnet 13. The magnet 13 can keep the tube groove 10 and the tube groove 2 9 relatively fixed. The outside of the magnet 13 is in contact with a T-block 14. The T-block 14 can make the tube groove 10 and the tube groove 2 9 only slide horizontally relative to each other. The right part of the T-block 14 is fixedly connected with the tube groove 2 9. The tube groove 2 9 and the tube groove 10 are fixed so that the circular groove is closed and only the two ends flow. The outside of the tube groove 29 is slidably connected to the middle interior of the lower mold 3, and the left end of the tube groove 29 is in contact with the side end of the tube groove 10.

[0034] Working principle: The telescopic rod 6 drives the lower mold 3 to slide and the upper mold 4 to close, so that injection molding can be carried out through the hole in the middle of the upper mold 4, and the hose 5 inputs the coolant into the connecting groove 8, and then the product is quickly cooled through the circular groove between the pipe groove 10 and the pipe groove 2 9. When there is a blockage inside, the connecting rod 15 can be slid, and the connecting rod 15 can drive the inclined surface block 12 to slide. The inclined surface block 12 squeezes and allows the U-shaped block 7 to slide into the lower mold 3, and then the connecting groove 8 can be slid out. At this time, the pipe groove 10 and the pipe groove 2 9 can be slid out for replacement. When the blockage is relatively clear, In a simple manner, the pipe groove 2 9 and the T-block 14 can be slid horizontally to slide out of the middle of the pipe groove 1 10 for cleaning, and then the T-block 14 can be slid into the pipe groove 1 10 so that the magnet 13 adsorbs the T-block 14. In this way, the pipe groove 1 10 and the pipe groove 2 9 are relatively fixed, and the cleaned or new pipe groove 1 10 and the pipe groove 2 9 can be slid into the lower mold 3, and then the connecting groove 8 is slid back to its original position, and the connecting rod 15 is released. The spring 11 squeezes the U-block 7 to slide into the connecting groove 8 and the interior of the pipe groove 1 10 and the pipe groove 2 9 to make them relatively fixed. At this time, the inclined block 12 and the connecting rod 15 are squeezed and slide back to their original positions.

[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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
