Description

Technical Field

[0001] This utility model relates to the field of machine tool base casting processing technology, specifically a casting mold for machine tool base processing. Background Technology

[0002] The machine tool base is one of the basic components of CNC machine tools. Currently, the machine tool base is mainly processed by casting. With the improvement of casting technology, the iron mold sand casting process has begun to be widely used in the casting process of machine tool bases. It is a casting process that combines the advantages of metal mold casting and sand casting, forming a mold by covering the inner cavity of the metal mold with a thin layer of molding sand.

[0003] The aforementioned casting molds are cooled by a cooling structure during the casting process to improve production efficiency and casting quality. Cooling is generally achieved through air cooling or water cooling via slots. However, air cooling is inefficient, and water cooling is difficult to match with complex mold structures, leading to localized overheating or overcooling and uneven heating. In severe cases, this can even result in damage to the mold and casting. Therefore, a casting mold for machining machine tool bases is proposed to address these issues. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, casting molds are cooled by cooling structures during the casting process to improve production efficiency and casting quality. Cooling is generally achieved through air cooling or water cooling via slots. However, air cooling is inefficient, and water cooling is difficult to match with complex mold structures, leading to localized overheating or undercooling and uneven heating. In severe cases, it can even damage the mold and the casting. This utility model proposes a casting mold for machining machine tool bases.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the casting mold for machining machine tool base according to this utility model includes a lower mold and an upper mold arranged symmetrically. The outer side of the lower mold and the outer side of the upper mold are both fixedly connected with a frame. The inner side of the lower mold and the inner side of the upper mold are both fixedly connected with a sand box. The interior of the lower mold and the interior of the upper mold are both provided with a spirally arranged cooling groove, and the cooling groove is located outside the sand box. One end of the frame is fixedly connected to the top surface with a liquid inlet pipe. One end of the liquid inlet pipe is provided with a sealing mechanism on the inner side. Two limiting blocks are fixedly connected inside the frame. A support plate is slidably connected to the opposite surfaces of the two pairs of limiting blocks in the center. Several liquid guiding grooves are opened on the inner side of the frame.

[0006] Preferably, the sealing mechanism includes a set of sealing blocks, one end of which has a pressure groove, and both sides of the sealing blocks are fixedly connected to sliders, one end of which is fixedly connected to a sealing spring.

[0007] Preferably, the top of the cooling tank has several input terminals, and the bottom of the cooling tank is fixedly connected to one end with a liquid outlet pipe. The input terminals at the top of the cooling tank are adapted to the liquid guide groove on the inner side of the frame.

[0008] Preferably, the side of the support plate is fitted with the liquid guiding groove, and a number of support springs are fixedly connected to the bottom of the support plate, with the end of the support spring away from the support plate being fixedly connected to the inner surface of the frame.

[0009] Preferably, the sealing block is located inside the liquid inlet pipe and is slidably connected to the liquid inlet pipe. Several sealing blocks are arranged in a ring array, and the sides of two adjacent sealing blocks are in contact. The pressure groove is arranged in an inclined shape.

[0010] Preferably, the top surface of the upper mold is fixedly connected to a feed port, and the feed port is fixedly connected to a sand box inside the upper mold.

[0011] The advantages of this utility model are: 1. This utility model delivers coolant into the frame through an inlet pipe. As the coolant is continuously supplied, pressure is applied to the frame, causing it to descend vertically. At this time, the coolant enters the cooling tank through several evenly distributed guide channels. The coolant is guided by the cooling tank surrounding the inner side of the sand box. As the coolant flows through the cooling tank, it carries away the high temperature emitted by the casting, achieving a cooling effect. When the coolant reaches the bottom of the cooling tank, it is discharged through an outlet pipe. This application, by setting a flow equalization component, allows the coolant to flow into the mold synchronously and evenly from different directions, reducing the problem of uneven heating of the mold, thereby ensuring the service life of the mold and the quality of the casting. 2. Through the structural design of the sealing mechanism, after the output end of the cooling equipment enters the inlet pipe, it squeezes the pressure groove, causing the sealing block to slide outward. When adjacent sealing blocks separate, the inlet pipe is in an open state. When the output end of the cooling equipment separates from the inlet pipe, the sealing block loses its limiting force. Under the action of the sealing spring, the slider and the sealing block are reset. The sealing block fits into the inside of the inlet pipe, achieving a sealing effect and closing the inlet pipe. The sealing component ensures the normal delivery of coolant and can automatically seal the cooling pipe groove when idle, reducing the problem of external dust penetration and contamination, and further extending the service life of the mold.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 one Figure 6 As shown, a casting mold for machining machine tool base includes a lower mold 1 and an upper mold 2 symmetrically arranged. A frame 4 is fixedly connected to the outer side of the lower mold 1 and the outer side of the upper mold 2. A sand box 7 is fixedly connected to the inner side of the lower mold 1 and the inner side of the upper mold 2. A spirally arranged cooling groove 8 is opened in the interior of the lower mold 1 and the interior of the upper mold 2, and the cooling groove 8 is located outside the sand box 7. One end of the frame 4 is fixedly connected to the top surface of the liquid inlet pipe 5. One end of the liquid inlet pipe 5 is provided with a sealing mechanism 12 on the inner side. Two limiting blocks 10 are fixedly connected inside the frame 4. The opposing surfaces of the two pairs of limiting blocks 10 are slidably connected to a support plate 11. Several liquid guiding grooves 9 are opened on the inner side of the frame 4. During operation, traditional molds use cooling structures to lower the temperature during the casting process, thereby improving production efficiency and casting quality. Cooling is generally achieved through air cooling or water cooling via slots. However, air cooling is inefficient, and water cooling is difficult to match with complex mold structures, leading to localized overheating or undercooling and uneven heating. In severe cases, it can even damage the mold and casting. Cooling tanks 8, which surround the inner side of the sand box 7, guide the coolant. As the coolant flows through the cooling tanks 8, it carries away the high temperature emitted by the casting, achieving a cooling effect.

[0017] Furthermore, the sealing mechanism 12 includes a set of sealing blocks 14, one end of which is provided with a pressure groove 15, and both sides of the sealing block 14 are fixedly connected with sliders 16, one end of which is fixedly connected with a sealing spring 17. During operation, the sealing mechanism 12 reduces the problem of external dust penetration. When the cooling pipe is separated from the liquid inlet pipe 5, the sealing block 14 loses its limiting force. Under the action of the sealing spring 17, the slider 16 and the sealing block 14 are reset. The sealing block 14 is fitted inside the liquid inlet pipe 5 to achieve a sealing effect, thereby closing the liquid inlet pipe 5, avoiding external dust contamination, and ensuring the service life of the cooling pipe.

[0018] Furthermore, the top of the cooling tank 8 is provided with several input terminals, and the bottom of the cooling tank 8 is fixedly connected to one end with a liquid outlet pipe 6. The input terminals at the top of the cooling tank 8 are adapted to the liquid guide channel 9 on the inner side of the frame 4. During operation, when the coolant flows to the bottom of the cooling tank 8, it is discharged through the outlet pipe 6, thus realizing the circulation of the coolant.

[0019] Furthermore, the side of the support plate 11 is in contact with the liquid guide groove 9, and several support springs 13 are fixedly connected to the bottom of the support plate 11. The end of the support spring 13 away from the support plate 11 is fixedly connected to the inner surface of the frame 4. During operation, coolant enters the frame 4 from the inlet pipe 5. As the coolant is continuously input, it exerts pressure on the frame 4, causing the frame 4 to drop vertically. At this time, the coolant enters the cooling tank 8 through several evenly distributed guide channels 9.

[0020] Furthermore, the sealing block 14 is located inside the liquid inlet pipe 5, and the sealing block 14 is slidably connected to the liquid inlet pipe 5. Several sealing blocks 14 are arranged in a ring array, and the sides of two adjacent sealing blocks 14 are in contact. The pressure groove 15 is arranged in an inclined shape. During operation, first connect the output end of the cooling device to the inlet pipe 5, then connect the input end of the cooling device to the outlet pipe 6. After the output end of the cooling device enters the interior of the inlet pipe 5, it contacts the pressure groove 15. As the input end continues to be inserted, it squeezes the pressure groove 15, causing the sealing block 14 to slide outward. The adjacent sealing blocks 14 separate, and the inlet pipe 5 is in the open state.

[0021] Furthermore, the top surface of the upper mold 2 is fixedly connected to the feed port 3, and the feed port 3 is fixedly connected to the sand box 7 inside the upper mold 2; During operation, the inside of the sand box 7 is first sandblasted and coated. Then, the lower mold 1 and the upper mold 2 are symmetrically attached and fixed with bolts. Then, the cooling equipment is connected. After that, the casting raw material is poured into the feed port 3. The raw material enters the inside of the sand box 7 along the feed port 3 and is cast inside the sand box 7 to form the machine tool base.

[0022] Working principle: First, the inside of the sand box 7 is sandblasted and coated. Then, the lower mold 1 and the upper mold 2 are symmetrically attached and fixed with bolts. Then, the output end of the cooling equipment is connected to the liquid inlet pipe 5, and the input end of the cooling equipment is connected to the liquid outlet pipe 6. After the output end of the cooling equipment enters the inside of the liquid inlet pipe 5, it contacts the pressure groove 15. As the input end is continuously inserted, it squeezes the pressure groove 15, causing the sealing block 14 to slide outward. The adjacent sealing blocks 14 separate, and the liquid inlet pipe 5 is in an open state. Then, the casting raw material is poured into the feed port 3. The raw material enters the inside of the sand box 7 along the feed port 3 and is cast inside the sand box 7 to form the machine tool base.

[0023] After casting is completed, the cooling equipment is started. Coolant enters the frame 4 from the inlet pipe 5. With the continuous input of coolant, pressure is generated on the frame 4, causing the frame 4 to drop vertically. At this time, the coolant enters the cooling tank 8 through several evenly distributed guide grooves 9. The coolant is guided by the cooling tank 8 surrounding the inner side of the sand box 7. When the coolant flows through the cooling tank 8, it carries away the high temperature emitted by the casting, achieving a cooling effect. When the coolant flows to the bottom of the cooling tank 8, it is discharged through the outlet pipe 6, realizing the circulation of coolant and continuously cooling the mold.

[0024] Until the cooling process is complete, the input and output ends of the cooling equipment are removed. When the output end of the cooling equipment is separated from the liquid inlet pipe 5, the sealing block 14 loses its limiting force. Under the action of the sealing spring 17, the slider 16 and the sealing block 14 are reset. The sealing block 14 is fitted inside the liquid inlet pipe 5 to achieve a sealing effect, thereby closing the liquid inlet pipe 5 and preventing external dust contamination. Then, the bolts are removed, and the lower mold 1 and the upper mold 2 are disassembled. The machine tool base casting inside the sand box 7 can then be taken out, and the casting process is complete.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
