Description

Technical Field

[0001] The present invention relates to the technical field of casting molds, and more particularly to a casting mold for processing heat-resistant steel castings. Background Art

[0002] A casting mold for processing steel castings is a tool used to pour molten steel into steel castings of specific shapes and sizes. When using a casting mold to cast steel castings, it is necessary to prepare suitable steel furnace charges according to the material requirements of the steel castings, such as scrap steel, pig iron, alloying elements, etc., and conduct strict inspections and batching calculations to ensure that the chemical composition of the molten steel meets the requirements. The furnace charges are added to furnaces such as electric furnaces and cupolas for melting. During the melting process, parameters such as temperature, chemical composition, and melting time should be strictly controlled, and a suitable refining process should be adopted to remove impurities, gases, etc. in the molten steel and improve the quality of the molten steel. When the molten steel reaches the specified temperature and composition, it is poured into the prepared casting mold. After pouring, the steel casting is allowed to cool naturally in the mold or cooled by forced cooling methods such as air cooling or water cooling to solidify the molten steel into a shape.

[0003] During repeated high-temperature casting and cooling processes, the mold material will undergo thermal fatigue due to the action of thermal stress, manifested as cracks on the mold surface, affecting the quality of the castings and the service life of the casting mold.

[0011] Furthermore, a fixed strip is rotatably sleeved on the side of the roller. Bearings are fixedly connected to both sides of the fixed strip.

[0013] The technical effects and advantages of the present invention: 1. The present invention is provided with a casting mold assembly. A casting cylinder for castings is provided in the middle part of the lower mold block. Heat-conducting fins are connected around the casting cylinder, and honeycomb heat dissipation holes are provided inside the lower mold block. The heat generated by the castings is dissipated from the inside of the lower mold block to the outside, avoiding the accumulation of heat between the casting cylinder and the lower mold block, thereby reducing the damage to the mold caused by thermal stress. In addition, the heat of the casting cylinder is conducted to the water tank by the heat-conducting fins, causing the water in the water tank to boil and generate a large amount of steam. By utilizing the kinetic energy and potential energy of the steam, the cylinder is driven to move, which is beneficial to reducing the damage to the mold caused by thermal stress and recycling a large amount of heat energy generated during the high-temperature casting or cooling process of the castings, improving the utilization rate of resources and reducing the electricity cost of enterprise production.

The heat of the casting cylinder is conducted to the water tank by the heat-conducting fins, causing the water in the water tank to boil and generate a large amount of steam. By utilizing the kinetic energy and potential energy of the steam, the cylinder is driven to move. The piston in the cylinder moves back and forth, causing the fan to rotate through the transmission assembly. Then, the wind is conveyed into the lower mold block through the wind pipe. The wind energy enables the air to flow rapidly, enhancing the heat exchange between the air and the surfaces of the mold and the castings. Then, the heat is taken away by the honeycomb heat dissipation holes. According to the principle of heat conduction, the flowing air can take away the heat on the surfaces of the mold and the castings faster, reducing the surface temperature and the temperature gradient between the inside and the surface of the mold and the castings. Since thermal stress is mainly caused by the uneven distribution of temperature, the reduction of the temperature gradient can effectively relieve the thermal stress, which is beneficial to reducing the damage to the mold caused by thermal stress during repeated high-temperature casting and cooling processes and improving the quality of the castings.

All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0018] Referring to Figure 1 , the present invention provides a casting mold for processing heat-resistant steel castings, including a die-casting mold assembly 1.

The bottom of the steam assembly 2 is connected to a heat dissipation assembly 3 through a pipeline, and both ends of the heat dissipation assembly 3 are connected to the die-casting mold assembly 1 through pipelines.

[0019] In this embodiment, it should be specifically supplemented that the die-casting mold assembly 1 avoids heat accumulation, thereby reducing the damage of the mold caused by thermal stress. In addition, the heat is used to boil water to generate a large amount of steam, and the kinetic energy and potential energy of the steam are utilized to drive the cylinder to move, which is beneficial to reducing the damage of the mold caused by thermal stress and recycling a large amount of heat energy generated during the high-temperature casting or cooling process of the casting, improving the utilization rate of resources and reducing the electricity cost of enterprise production. The steam assembly 2 is beneficial to reducing the damage of the mold caused by thermal stress during repeated high-temperature casting and cooling processes and improving the quality of the casting. The specific structures and working principles of the above components will be described in detail later.

Heat-conducting fins 1013 are connected around the pouring cylinder 1012, and honeycomb heat dissipation holes 1015 are provided inside the lower mold block 1011 to disperse the heat generated by the casting from the inside of the lower mold block 1011 to the outside, avoiding the accumulation of heat between the lower mold block 1011 and the pouring cylinder 1012, thereby reducing the damage of the mold caused by thermal stress. In addition, the heat of the pouring cylinder 1012 is conducted to the steam assembly 2 by the heat-conducting fins 1013, so that the water in the steam assembly 2 boils to generate a large amount of steam. By utilizing the kinetic energy and potential energy of the steam to drive the heat dissipation assembly 3, it is beneficial to reduce the damage of the mold caused by thermal stress and recycle a large amount of heat energy generated during the high-temperature casting or cooling process, improving the utilization rate of resources and reducing the electricity cost of enterprise production.

After the casting cylinder 1012 is filled with casting material, the fixed round rods 1023 are placed corresponding to the limiting round holes 1014, and at the same time, the die-casting sheet 1024 corresponds to the casting cylinder 1012, and the gravity of the upper die assembly 102 itself is used to die-cast the casting material in the casting cylinder 1012.

[0025] Referring to Figure 7 , the steam assembly 2 includes a water tank 201. A steam chamber assembly 202 is fixedly connected in the middle of the water tank 201. A steam pipe 203 is connected to the bottom of the water tank 201 through a pipeline, and a water inlet pipe 204 is connected to one side of the water tank 201 through a pipeline.

[0026] In this embodiment, it should be specifically supplemented that there is a space between the water tank 201 and the steam chamber assembly 202, and there is water in the space. The bottom ends of the four heat-conducting sheets 1013 are all in the water in this space. The top end of the steam pipe 203 is communicated with the steam chamber assembly 202, and the water inlet pipe 204 is used to supplement the water between the water tank 201 and the steam chamber assembly 202.

[0027] Referring to Figure 8 , the steam chamber assembly 202 includes an intermediate air chamber 2021, and a steam-permeable hole 2022 is provided at the top end of the side of the intermediate air chamber 2021.

[0028] In this embodiment, it should be specifically supplemented that the water between the water tank 201 and the steam chamber assembly 202 is heated by the heat transferred by the heat-conducting sheets 1013 and boils and evaporates to generate a large amount of steam. The steam enters the inside of the intermediate air chamber 2021 through the steam-permeable hole 2022 and is then transferred to the heat dissipation assembly 3 through the steam pipe 203.

[0029] Referring to Figure 9 , the heat dissipation assembly 3 includes an intermediate pipe 301. The top of the intermediate pipe 301 is connected to the steam pipe 203 through a pipeline. Both ends of the intermediate pipe 301 are connected to a cylinder assembly 302 through pipelines. One end of each of the two cylinder assemblies 302 is fixedly connected to a pneumatic fan assembly 303. The top ends of the two pneumatic fan assemblies 303 are connected to the casting mold assembly 101 through pipelines.

[0030] Referring to Figure 10, the cylinder assembly 302 includes a movable cylinder 3021, a piston 3022 is movably sleeved inside the movable cylinder 3021, one end of the piston 3022 is fixedly connected to a connecting member 3023, a first connecting rod 3024 is rotatably sleeved inside the connecting member 3023, one side of each end of the first connecting rod 3024 is fixedly connected to a connecting strip 3025, one end of the two connecting strips 3025 is fixedly connected to a second connecting rod 3026, the pneumatic fan assembly 303 includes a rotating disc 3031, the edge of the bottom of the rotating disc 3031 is fixedly connected to the second connecting rod 3026, a roller 3032 is fixedly connected to the top of the rotating disc 3031, a fixing strip 3033 is rotatably sleeved on the side surface of the roller 3032, bearings 3034 are fixedly connected to both sides of the fixing strip 3033, the top end of the roller 3032 is fixedly connected to a fan 3035, and both ends of the two bearings 3034 are fixedly connected to a wind duct 3036 and are connected to the inner wall of the wind duct 3036.

[0031] In this embodiment, it should be specifically supplemented that the heat of the pouring cylinder 1012 is conducted to the water tank 201 by the heat conducting sheet 1013, so that the water in the water tank 201 boils to generate a large amount of steam. Then, the kinetic energy and potential energy of the steam are utilized to drive the movement of the cylinder assembly 302. The piston 3022 in the cylinder assembly 302 moves back and forth. Through the transmission assembly, the fan 3035 rotates. Then, the wind is conveyed to the pouring mold assembly 101 through the wind duct 3036. The wind energy enables the air to flow quickly, enhancing the heat exchange between the air and the surfaces of the mold and the casting. Then, the heat is taken away by the honeycomb heat dissipation holes 1015. According to the heat conduction principle, the flowing air can take away the heat on the surfaces of the mold and the casting faster, reducing the surface temperature and decreasing the temperature gradient between the inside and the surface of the mold and the casting. Since the thermal stress is mainly caused by the uneven distribution of temperature, the reduction of the temperature gradient can effectively relieve the thermal stress, which is beneficial to reducing the damage caused by the thermal stress to the mold during the repeated high-temperature casting and cooling processes and improving the quality of the casting.

[0032] Working principle of the present invention: A casting cylinder 1012 for castings is provided in the middle of the lower die block 1011. Heat-conducting fins 1013 are connected around the casting cylinder 1012, and honeycomb heat dissipation holes 1015 are provided inside the lower die block 1011 to evacuate the heat generated by the casting from the inside of the lower die block 1011 to the outside, avoiding the accumulation of heat between the lower die block 1011 and the casting cylinder 1012, thereby reducing the damage to the die caused by thermal stress. In addition, the heat-conducting fins 1013 are used to conduct the heat of the casting cylinder 1012 to the steam assembly 2, causing the water in the steam assembly 2 to boil and generate a large amount of steam. By utilizing the kinetic energy and potential energy of the steam to drive the heat dissipation assembly 3, it is beneficial to reduce the damage to the die caused by thermal stress and recycle a large amount of heat energy generated during the high-temperature casting or cooling process of the casting, improving the utilization rate of resources and reducing the electricity cost of enterprise production.

[0033] Then, the heat-conducting fins 1013 are used to conduct the heat of the casting cylinder 1012 to the water tank 201, causing the water in the water tank 201 to boil and generate a large amount of steam. By utilizing the kinetic energy and potential energy of the steam to drive the movement of the cylinder assembly 302, the piston 3022 in the cylinder assembly 302 moves back and forth. Through the transmission assembly, the fan 3035 rotates. Then, the wind is conveyed to the casting die assembly 101 through the wind pipeline 3036. The wind energy enables the air to flow quickly, enhancing the heat exchange between the air and the surfaces of the die and the casting. Then, the heat is taken away by the honeycomb heat dissipation holes 1015. According to the heat conduction principle, the flowing air can take away the heat on the surfaces of the die and the casting faster, reducing the surface temperature and decreasing the temperature gradient between the inside and the surface of the die and the casting. Since the thermal stress is mainly caused by the non-uniform distribution of temperature, the reduction of the temperature gradient can effectively relieve the thermal stress, which is beneficial to reducing the damage to the die caused by thermal stress during the repeated high-temperature casting and cooling processes and improving the quality of the casting.
