Its function is to quickly reduce the temperature of the projectile by exchanging heat with the high-temperature projectile through a specific cooling medium, so that it can be cooled from the high temperature state after casting to the temperature range required for subsequent processing or treatment. The device is usually designed with corresponding bearing structure, medium conveying system and temperature control components according to the shape, size and cooling process requirements of the projectile to achieve effective control of the projectile cooling process and ensure the stable performance and production continuity of the projectile after casting.

[0031] The positioning assembly 11 comprises a mold shell 111, a guide sliding groove 112 and a high-temperature-resistant buffer pad 113. The guide sliding groove 112 is arranged on the surface of the mold shell 111. The high-temperature-resistant buffer pad 113 is fixedly connected to the bottom of the inner side of the mold shell 111. By arranging the positioning assembly 11, the mold shell 111 can be matched with the guide sliding groove 112 and the high-temperature-resistant buffer pad 113. The mold shell 111 can temporarily store the elastomer casting and the sand mold. The mold shell 111 can form a closed space together with the heat dissipation assembly 12 and the adjusting assembly 21. The up-down movement of the heat dissipation assembly 12 can be guided by the guide sliding groove 112.

At the same time, the temperature control component 13 can be limited, and the heat conducting plate 122 and the guide slider 121 can be driven to move along with the temperature control component 13 to adapt to the position of the temperature control component 13 after deformation.

[0033] Among them, the temperature control component 13 includes a heat transfer sleeve 131, a high temperature resistant corrugated hose 132 and a combination ring 133. The heat transfer sleeve 131 is clamped on the inner side of the heat dissipation fin 123, the high temperature resistant corrugated hose 132 is connected to the top of the heat transfer sleeve 131, and the combination ring 133 is connected to the top of the high temperature resistant corrugated hose 132. By setting the temperature control component 13, the heat transfer sleeve 131 can cooperate with the high temperature resistant corrugated hose 132 and the combination ring 133, and the high temperature resistant corrugated hose 132 is limited by the heat transfer sleeve 131. The combination ring 133 can connect the current high temperature resistant corrugated hose 132 with another identical heat transfer sleeve 131, and can allow the most The assembly ring 133 at the top is connected to the conveying assembly 16, allowing the heat transfer sleeve 131 at the bottom to be connected to the air valve 231, forming a passage for the heat flow in the mold shell 111 to be transported to the regulating assembly 21. In addition, the high-temperature resistant corrugated hose 132 can use the heat transfer sleeve 131 as a support point to expand according to its own high-temperature resistance and flexibility, and the characteristics of heat flow due to thermal expansion, thereby increasing the distance between the heat transfer sleeve 131 and the assembly ring 133. Therefore, the spacing of the heat dissipation fins 123 can be adjusted together. Increasing the spacing between each heat dissipation fin 123 increases the efficiency of the external air flow in removing heat, thereby improving the efficiency of cooling the projectile.

[0034] Among them, the guide assembly 14 includes a guide frame 141, an interception mesh plate 142 and an air supply hole plate 143. The guide frame 141 is clamped on the top of the inner side of the mold shell 111, the interception mesh plate 142 is clamped on the bottom of the inner side of the guide frame 141, and the air supply hole plate 143 is fixedly connected to the inner side of the guide frame 141. The bottom of the air supply hole plate 143 contacts the top of the interception mesh plate 142. By setting the guide assembly 14, the guide frame 141 can cooperate with the interception mesh plate 142 and the air supply hole plate 143. The guide frame 141 limits the intercepting mesh plate 142 and the air supply hole plate 143, so that the air supply hole plate 143 can block the intercepting mesh plate 142 according to its own porous design. When the bottom of the intercepting mesh plate 142 contacts the sand mold, the sand mold can be intercepted, and the heat flow transported from the holes of the sand mold can be transported to the centralized component 15 through the air supply hole plate 143, thereby providing heat flow for the centralized component 15, and the intercepting mesh plate 142 can be disassembled and assembled from the guide frame 141 for easy subsequent cleaning and maintenance.

[0035] Among them, the centralized component 15 includes a centralized pipe 151, an assembly frame 152 and an assembly plate 153. The centralized pipe 151 is connected to the top of the guide frame 141, the assembly frame 152 is fixedly connected to the top of the centralized pipe 151, and the assembly plate 153 is clamped on the inner side of the assembly frame 152. By setting the centralized component 15, the centralized pipe 151 can cooperate with the assembly frame 152 and the assembly plate 153, and the transported heat flow is gradually gathered upward through the centralized pipe 151, and the air flow rate is increased in a gathering manner, so that the heat flow can be transported to the conveying component 16. The assembly frame 152 can temporarily limit the assembly plate 153 with the top of the centralized pipe 151 as the support point. The assembly plate 153 can be assembled with the assembly frame 152 through its own snap-in structure to form a closed air conveying channel, which transports the heat flow to the conveying component 16, and the bayonet structure can facilitate the disassembly and maintenance of the conveying component 16 from the assembly frame 152 along the assembly plate 153.

By setting the conveying component 16, the conveying pipe 161 can cooperate with the buffer sleeve 162 and the connecting pipe 163, and the heat flow is conveyed to the connecting pipe 163 through the conveying pipe 161, and the connecting pipe 163 can convey the heat flow to the combination ring 133, thereby providing heat flow for the introduction component 23. The buffer sleeve 162 can protect the bending part of the conveying pipe 161 and increase the structural stability of the bending part of the conveying pipe 161. The connecting pipe 163 can facilitate the disassembly and assembly of the conveying pipe 161 from the combination ring 133, thereby facilitating the subsequent disassembly and maintenance of the connecting pipe 163.

[0037] The working principle of this embodiment is as follows: First, the elastomeric casting and the corresponding sand mold are placed in the mold shell 111, and then the guide frame 141 is installed on the mold shell 111. When the casting needs to be cooled, the mold shell 111 is moved to a flowing air environment, and then the flowing air is used to take away the heat from the mold shell 111 to achieve cooling. During the cooling process, the sand mold will transfer the heat flow upward through its own holes to each corresponding central pipe 151, and then transfer it to the delivery pipe 161 through the central pipe 151, and then from the delivery pipe 161 through the connecting pipe 163 to the combination ring 13 3. Then, the heat flow will be transported from the heat transfer pipe sleeve 131 to the corresponding adaptation mechanism 2 through each corresponding high-temperature resistant corrugated hose 132. At this time, the high-temperature resistant corrugated hose 132 will stretch as the heat flow expands, and at the same time, the distance between the high-temperature resistant corrugated hose 132 and the heat transfer pipe sleeve 131 will increase. The heat transfer pipe sleeve 131 will drive the heat dissipation fins 123 to move together with the heat conduction plate 122 and the guide slider 121. The guide slider 121 will move along the guide groove 112. Then, the outside air will take away the heat on the heat dissipation fins 123 until the casting is cooled.

[0038] Example 2 refer to Figure 9-12A projectile casting cooling device that can eliminate internal defects also includes an adaptive mechanism 2, wherein the adaptive mechanism 2 includes an adjusting component 21, a transmission component 22 and an introduction component 23.

By setting the adaptive mechanism 2, the adjusting component 21 can cooperate with the transmission component 22 and the introduction component 23, and the heat flow delivered from the cooling mechanism 1 is sent into the transmission component 22 through the introduction component 23. The air pressure between the transmission component 22 and the adjusting component 21 can be changed, so that the adjusting component 21 is lifted upward along the transmission component 22, pushing the sand mold at the corresponding contraction point of the casting, compensating the sand mold to the cavity caused by the contraction of the casting, and improving the stability of the sand mold during continuous cooling.

[0039] Among them, the adjusting component 21 includes an adjusting frame 211, an adjusting push plate 212 and an adjusting piston rod 213.
