[0034] 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.

[0035] Reference Figure 1-Figure 2The utility model provides an embodiment: a sample mold for a direct reading spectrometer, comprising a lower mold 1, the top of the lower mold 1 is threadedly connected to an upper mold 2, a mold groove 3 is placed in the middle of the lower mold 1, and a material injection port 4 is opened in the middle of the upper mold 2. After the mold groove 3 is placed inside the lower mold 1 and the upper mold 2 is installed, a complete mold is formed. At this time, only the solder solution needs to be injected from the material injection port 4, and the sample molding operation can be completed after the solder solution is cooled. A cooling component is arranged inside the lower mold 1, and the cooling component includes a water inlet pipe 14 and a drain pipe 15. The water inlet pipe 14 and the drain pipe 15 are both installed in the middle of the lower mold 1 and are connected to the internal cavity of the lower mold 1. During the molding process, a normal temperature or cooling solution can be injected from the water inlet pipe 14. After the cooling solution enters the internal cavity of the lower mold 1, it contacts the mold groove 3, so that the heat of the mold groove 3 can be taken out. After continuous solution injection, the cooling speed of the sample can be accelerated, greatly improving the molding efficiency. At the same time, a one-way valve 16 is installed in the middle of the water inlet pipe 14 and the drain pipe 15. The one-way valve 16 can prevent the solution from flowing back, thereby ensuring the normal injection of the cooling solution. It should be noted that the cooling solution mentioned here can be but is not limited to water.

[0036] Reference Figure 2-Figure 4 , a protrusion 6 is fixedly connected to the outside of the mold groove 3, and a circular ring 12 is fixedly connected to the inside of the lower mold 1. The protrusion 6 overlaps the upper part of the circular ring 12. When the mold groove 3 is placed inside the lower mold 1, the protrusion 6 overlaps the upper part of the circular ring 12 to provide support for the mold groove 3 as a whole. In this way, a cavity can be formed inside the lower mold 1 to facilitate the injection of the cooling solution. A sealing ring 13 is fixedly connected to the inside of the circular ring 12. The outer surface of the sealing ring 13 abuts against the outer surface of the mold groove 3. The sealing ring 13 ensures the sealing between the mold groove 3 and the circular ring 12 to prevent the cooling solution injected into the cavity inside the lower mold 1 from overflowing upward.

[0037] Reference Figure 2-Figure 4 , a plurality of positioning blocks 5 are fixedly connected to the inner edge of the lower mold 1, and the mold groove 3 is connected to the lower mold 1 through a clamping assembly. After the mold groove 3 is placed on the upper part of the ring 12, the mold groove 3 is rotated so that the protrusion 6 can be inserted into the gap between the positioning block 5 and the ring 12, so as to achieve the preliminary fixation of the mold groove 3, and then the installation of the mold groove 3 can be completed by the clamping assembly;

[0038] Reference Figure 2 , Figure 3 and Figure 6The clamping assembly includes a clamping rod 8, which is slidably connected to the middle part of the lower mold 1. A spring 9 is sleeved on the outside of the clamping rod 8. A clamping groove 7 is opened on the outside of the protrusion 6. The clamping groove 7 and the clamping rod 8 are clamped together. When the clamping rod 8 is pulled outward, the inner end of the clamping rod 8 can be separated from the middle part of the clamping groove 7. At this time, the restricting effect on the mold groove 3 can be cancelled, and the mold groove 3 can be rotated, so that the mold groove 3 can be removed and replaced conveniently. A limiting groove 11 is provided on the outer side of the lower mold 1, and a limiting block 10 is fixedly connected to the outer side of the clamping rod 8. The sizes of the limiting block 10 and the limiting groove 11 are matched. At least two clamping components are arranged on the outer side of the lower mold 1 to ensure the stability of the installation of the mold groove 3. During operation, especially when removing the mold groove 3, after pulling the clamping rod 8 outward, rotating the clamping rod 8 can make the limiting block 10 and the limiting groove 11 vertical and staggered. At this time, the limiting block 10 overlaps the outer side of the lower mold 1, which can limit the clamping rod 8, thereby ensuring the effective replacement of the mold groove 3.

[0039] Reference Figure 4 and Figure 5 A sealing ring 17 is fixedly connected to the top of the mold groove 3, and a sealing groove 18 is opened at the bottom of the upper mold 2. The sealing ring 17 and the sealing groove 18 are clamped together. The additional sealing ring 17 and the sealing groove 18 facilitate the positioning of the mold groove 3, and at the same time ensure that a closed space can be formed between the upper mold 2 and the mold groove 3 after the upper mold 2 is installed, thereby ensuring the normal molding operation. A handle 19 is fixedly connected to the top of the upper mold 2. By adding the handle 19, the lower mold 1 and the upper mold 2 can be easily separated to facilitate sampling and replacement of the mold groove 3.

[0040] Working principle: After the lower mold 1 and the upper mold 2 are threadedly connected, the solder solution is injected through the injection port 4, causing the solder solution to cool and form. During the forming process, room temperature or low temperature liquid can be injected from the water inlet pipe 14 to reduce the temperature of the internal cavity of the lower mold 1. The injected solution is discharged from the lower mold 1 through the drain pipe 15. The solution is continuously injected to accelerate the cooling speed of the solder solution and improve the cooling efficiency. After the sample is cooled, the upper mold 2 can be twisted to complete the separation operation of the lower mold 1 and the upper mold 2, thereby facilitating the removal of the sample.

[0041] When the samples of different models or shapes are to be molded, the inner end of the card rod 8 is disengaged from the card slot 7 by pulling the card rod 8 outwards. At this time, the card rod 8 is rotated to disengage the limit block 10 from the limit slot 11. After the card rod 8 is released, the card rod 8 is in a standby state under the influence of the limit block 10, and the spring 9 is in a contracted state due to the pressure. At this time, the protrusion 6 and the mold slot 3 can move freely. At this time, the mold slot 3 is rotated so that the protrusion 6 is located in the gap between the plurality of positioning blocks 5, and then the mold slot 3 can be taken out as a whole upward. Then the mold slot 3 that can be used to make samples of other models and specifications is put back in, and the mold slot 3 is rotated so that the card slot 7 is aligned with the card rod 8 again, and the limit block 10 is aligned with the limit slot 11. After the card rod 8 is released, the card rod 8 is reinserted into the card slot 7 under the elastic action of the spring 9, so that the connection of the new mold slot 3 is completed. At this time, the production of samples of new models and specifications can be completed.

[0042] 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.
