[0002] Die-casting molds are key components used in the die-casting process. They enable liquid or semi-liquid metal to quickly fill the mold cavity under high pressure and rapidly cool and solidify to form the desired shape. These molds are usually made of materials with high heat resistance, wear resistance, and strength, such as special alloy steels, to withstand the high temperature and pressure generated during die-casting. By precisely designing the geometric shape of the mold cavity, metal parts with complex structures and high surface quality can be ensured to be produced.

[0003] Deficiencies of existing die-casting molds:

[0004] Firstly: In the die-casting process, due to the slow cooling rate of the product after die-casting, the mold cannot be removed quickly, which leads to a reduction in production efficiency, an increase in energy consumption and production costs. In addition, the long-term high temperature may also exacerbate mold wear and shorten its service life.

[0005] Secondly: During die-casting, the workpiece being die-cast is tightly connected to the mold and is not easy to remove, and the workpiece adhering tightly to the mold affects the production progress. Content of the Utility Model

[0013] The technical effects and advantages of the present utility model:

[0014] 1. When the present utility model is in use, the air cylinder is started to make the telescopic rod move downward. At this time, the lower pressing plate moves downward. When the lower pressing plate moves downward, the round rod and the cover plate move downward. At this time, the solution is injected into the mold box through the injection port. At this time, the pressing mold coincides with the lower mold. Subsequently, the air extraction pump is started to extract air from the outside through the air inlet. At this time, the air enters the air guiding pipe through the air extraction pump. Subsequently, the air guiding pipe transmits the air to the condensation pipe. When the air enters the condensation pipe, the temperature begins to decrease. Finally, the cold air is transmitted to the air duct, and the air duct transmits the cold air to the cooling pipe. At this time, the temperature of the mold box begins to rapidly decrease, which is beneficial to rapidly reducing the temperature of the mold box during the die pressing process, can significantly improve production efficiency, shorten the cooling time of the product in the mold, speed up the production process. At the same time, this also helps to improve product quality, reduce deformation caused by uneven cooling, and improve the dimensional accuracy and surface quality of the product.

[0015] 2. When the cooling is completed, the pressing mold is moved upward. At this time, the spring begins to contract. At this time, the folding block folds towards both sides of the mold box in the square groove. At this time, the bottom of the folding block will push up the solidified workpiece, which is beneficial to helping the workpiece quickly break away from the mold, greatly shortening the demolding time, and improving the overall production efficiency.

[0024] In a preferred embodiment, the top of the round rod 101 is fixedly connected to the lower pressing plate 1, the bottom of the round rod 101 is fixedly connected to a pressing die 102, the top of the cover plate 103 is fixedly connected to an injection port 104, the bottom of the lower pressing plate 1 is fixedly connected to a telescopic rod 105, and the bottom of the telescopic rod 105 is movably connected to a cylinder 106.

[0025] In a preferred embodiment, a workbench 201 is fixedly connected to the bottom of the mold box 2, feet 202 are fixedly connected to the bottom of the workbench 201, a cooling pipe 203 is fixedly connected to the inner surface of the mold box 2, an air duct 407 is fixedly connected to the bottom of the cooling pipe 203, an air outlet 204 is provided at the top of the mold box 2, and an air permeable opening 207 is provided at the bottom of the equipment box 206.

[0026] In a preferred embodiment, a folding block 301 is movably connected to the inner surface of the square groove 3. Both ends of the folding block 301 are fixedly connected to a central shaft 302, both ends of the central shaft 302 are fixedly connected to the square groove 3, and a spring 303 is fixedly connected to one side of the folding block 301.

[0027] In a preferred embodiment, an air inlet 401 is fixedly connected to one side of the air extraction pump 4, an air guiding pipe 402 is fixedly connected to the top of the air extraction pump 4, a condensation pipe 403 is fixedly connected to one side of the air guiding pipe 402, frames 404 are fixedly connected to both sides of the condensation pipe 403, a connecting block 405 is fixedly connected to the top of the frame 404, the connecting block 405 is fixedly connected to the workbench 201, a dryer 408 is fixedly connected to one side of the frame 404, and a fan 406 is fixedly connected to the bottom of the frame 404.

[0028] In a preferred embodiment, the angle between the spring 303 and the folding block 301 is thirty degrees.

[0029] Working principle of the utility model: When the starting cylinder 106 is used to move the telescopic rod 105 downward, at this time the lower pressing plate 1 moves downward. After the lower pressing plate 1 moves downward, the round rod 101 and the cover plate 103 move downward. At this time, the solution is injected into the mold box 2 through the injection port 104. At this time, the pressing mold 102 coincides with the lower mold 205. Subsequently, the air inlet 401 of the air extraction pump 4 starts to extract air to the outside.

At the same time, this also helps to improve the product quality, reduce the deformation caused by uneven cooling, and improve the dimensional accuracy and surface quality of the product. When the cooling is over, the pressing mold 102 is moved upward. At this time, the spring 303 starts to contract. At this time, the folding block 301 opens and folds to both sides of the mold box 2 in the square groove 3. At this time, the bottom of the folding block 301 will push up the solidified workpiece, which is beneficial to help the workpiece quickly break away from the mold, greatly shortening the demolding time and improving the overall production efficiency.
