Through the dispersion assembly, the liquid ammonia from the output liquid ammonia pump enters the horizontal shunt pipe 7 through the liquid ammonia output pipe 6, and then is delivered to the embedded condensing pipe 9, the second horizontal condensing pipe 11 and the first horizontal condensing pipe 15 through multiple vertical output pipes 8, and is uniformly sprayed on the objects to be cooled through the liquid ammonia nozzles 25 on these pipes. This dispersion design ensures that the liquid ammonia can fully cover the objects to be cooled, improves the cooling efficiency and uniformity, helps to quickly reduce the mold temperature, and improves the production efficiency. The clamping assembly adopts the design of L-shaped clamping plate 21 cooperating with inclined guide rod 22 and vertical guide rod 17, which makes the clamping process stable and flexible. The L-shaped clamping plate 21 can be flexibly adjusted in angle on the first concave mounting seat 26 through the rotating roller, and is suitable for molds of different shapes and sizes. The spring design on the inclined guide rod 22 and the vertical guide rod 17 provides the function of automatic adaptation and tightening, ensuring that the mold remains stable during the cooling process, while avoiding damage caused by excessive clamping. Through the recovery liquid ammonia pump 13 and the recovery liquid ammonia pipe 14, the device can recover the liquid ammonia that has not completely evaporated from the bottom of the box body 1 and re-inject it into the liquid ammonia storage tank 5, realizing the recycling of liquid ammonia. This not only reduces production costs, but also reduces environmental pollution, in line with the concept of green production. The whole device has a compact structure, is convenient for daily maintenance and repair, and the door plate 2 connected by the hinge 3 can be easily opened for cleaning the inside of the box body 1 and replacing damaged parts.Meanwhile, the mounting blocks 16 and mounting seats on the bearing plate 10 are also designed to facilitate the adjustment of the position and angle of the clamping assembly to adapt to different production needs. Through reasonable layout and sealing design, the risk of liquid ammonia leakage is effectively prevented, and the safety during production is improved. At the same time, the ingenious design of the dispersion assembly and the clamping assembly also reduces the direct contact of the operator with liquid ammonia, further ensuring the safety of the operator.

[0030] Further, in the present example, as shown in Figure 1 , Figure 3 and Figure 5 , the dispersion assembly includes a horizontal distribution pipe 7, the upper end of which is installed at the bottom end of the liquid ammonia output pipe 6, and the bottom end of the horizontal distribution pipe 7 is provided with a plurality of vertical output pipes 8, the bottom end of which is installed at the top of the box body 1, and the top of the box body 1 is provided with a through hole with the same diameter as the vertical output pipe 8 at the position corresponding to the bottom end of the vertical output pipe 8, and a plurality of vertical output pipes 8 are installed with embedded condenser pipes 9 through the through hole, and a plurality of embedded condenser pipes 9 are installed on the side wall of the box body 1, the bottom end of the embedded condenser pipe 9 is abutted and installed on the bottom wall of the box body 1, and a plurality of embedded condenser pipes 9 are installed on the middle side wall of the embedded condenser pipe 9, and a plurality of embedded condenser pipes 9 are installed on the top side wall of the embedded condenser pipe 9 and the bottom side wall of the embedded condenser pipe 9, and a plurality of embedded condenser pipes 9, second horizontal condenser pipes 11 and first horizontal condenser pipes 15 are provided with liquid ammonia nozzles 25 on the side wall, and the directions of the liquid ammonia nozzles 25 are different, when the liquid ammonia cooling device is started, the liquid ammonia in the liquid ammonia storage tank 5 is pumped out by the output liquid ammonia pump, and is transported along the liquid ammonia output pipe 6 into the horizontal distribution pipe 7. During this process, the output liquid ammonia pump provides the necessary pressure to ensure the smooth flow of liquid ammonia. The horizontal distribution pipe 7 receives liquid ammonia from the liquid ammonia output pipe 6 and distributes it to a plurality of vertical output pipes 8. These vertical output pipes 8 are evenly distributed along the top of the box body 1, ensuring that liquid ammonia can cover every corner of the box body 1. The bottom end of each vertical output pipe 8 is connected to an embedded condenser pipe 9, which extends along the side wall and bottom wall of the box body 1, forming a complex condensation network. On the side wall of the embedded condenser pipe 9, second horizontal condenser pipe 11 and first horizontal condenser pipe 15, there are a plurality of liquid ammonia nozzles 25. The design of these nozzles allows liquid ammonia to be sprayed at different angles and directions, forming a dense mist of liquid ammonia. These droplets can quickly cover the surface of the mold, achieving rapid cooling. Because the directions of the liquid ammonia nozzles 25 are different, they can form a cross-spraying effect, ensuring that each part of the mold is fully cooled. At the same time, the complex layout of the embedded condenser pipe 9, second horizontal condenser pipe 11 and first horizontal condenser pipe 15 also increases the contact area of liquid ammonia with the surface of the mold, further improving the cooling efficiency.

[0031] Further, in the present example, as Figure 3 and Figure 4As shown, the clamping assembly includes a first concave mount 26 installed on the upper surface of the bearing plate 10, and a rotating roller is installed on the inner wall of the groove of the first concave mount 26, and an L-shaped clamping plate 21 is rotatably installed on the rotating roller, and a diagonal guide rod 22 is installed at the top end of the long arm of the L-shaped clamping plate 21, and a circular groove with the same diameter as the diagonal guide rod 22 is opened at the top end of the long arm of the L-shaped clamping plate 21 corresponding to the position of the diagonal guide rod 22, and a contact block 24 is installed at one end of the diagonal guide rod 22, and a diagonal spring 23 is installed on the diagonal guide rod 22, and one end of the diagonal spring 23 is abutted and installed on the top end side wall of the L-shaped clamping plate 21, and the other end of the diagonal spring 23 is abutted and installed on the side wall of the contact block 24, and a second concave mount 19 is installed at the bottom end of the short arm of the L-shaped clamping plate 21, and a rotating rod 20 is installed on the inner wall of the groove of the second concave mount 19, and a vertical guide rod 17 is rotatably installed on the rotating rod 20, and a hole with the same diameter as the rotating rod 20 is opened at the top end of the vertical guide rod 17 corresponding to the position of the rotating rod 20, and a vertical spring 18 is installed on the vertical guide rod 17, and the top end of the vertical spring 18 is abutted and installed on the side wall of the rotating rod 20, and the bottom end of the vertical spring 18 is abutted and installed on the upper end face of the bearing plate 10, and a hole with the same diameter as the vertical guide rod 17 is opened on the bearing plate 10 corresponding to the position of the vertical guide rod 17. First, the operator places the mold to be cooled on the bearing plate 10. The design of the bearing plate 10 allows the mold to be placed stably on it without sliding or tilting. The L-shaped clamping plate 21 is flexibly adjusted in angle on the first concave mount 26 through the rotating roller to adapt to the shape and size of the mold. The operator can manually adjust the position and angle of the L-shaped clamping plate 21 according to the actual size of the mold to ensure that the clamping plate can closely fit the surface of the mold. After the L-shaped clamping plate 21 is adjusted to the appropriate position, the diagonal guide rod 22 and the diagonal spring 23 begin to play a role. One end of the diagonal guide rod 22 is connected with the contact block 24, and the other end passes through the circular groove on the L-shaped clamping plate 21 and is fixed on the bearing plate 10. The diagonal spring 23 is installed on the diagonal guide rod 22 and generates a certain elastic force. This elastic force allows the L-shaped clamping plate 21 to tightly clamp the mold to prevent it from moving or deforming during the cooling process. In addition to the diagonal guide rod 22 and the diagonal spring 23, the vertical guide rod 17 and the vertical spring 18 also play a role in auxiliary clamping. One end of the vertical guide rod 17 is connected with the second concave mount 19, and the other end passes through the hole on the bearing plate 10 and is fixed on the box body 1. The vertical spring 18 is installed on the vertical guide rod 17 and generates an upward elastic force. This elastic force allows the bearing plate 10 to maintain a certain tension, further enhancing the clamping effect. Through the coordinated action of the diagonal guide rod 22, the diagonal spring 23, the vertical guide rod 17 and the vertical spring 18, the clamping assembly can not only ensure the stability of the mold during the cooling process, but also adapt to molds of different shapes and sizes. This design not only improves the cooling efficiency, but also reduces the operation difficulty and cost.
