Description

Technical Field

[0001] This utility model relates to the field of sculpture mold technology, and more specifically, to a 3D sculpture mold device with a water circulation cooling structure. Background Technology

[0002] 3D sculpture is a type of sculpture that uses three-dimensional space to express artistic images. 3D sculpture molds are tools used to manufacture 3D sculpted plastic products, which can mass-produce sculpted parts with complex appearances. Existing 3D sculpture molds are mainly silicone molds, plaster molds, and metal molds. Among them, metal molds are used for mass production of metal sculptures, such as aluminum die casting or iron casting. Because metal sculptures are at high temperatures during processing, they need to be cooled and shaped by a water circulation cooling structure.

[0003] Currently, sculpture molds have different size requirements, so the mold core is changed to adapt to the sculpture requirements. When the sculpture inside the mold core is cooled, cooling water flows directly in the cooling pipe to cool the mold core. This traditional cooling method has a significant shortcoming of poor cooling coverage. When the mold core is used to cool large-sized sculptures, a single cooling pipe cannot cover the entire range of the large-sized sculpture, resulting in low cooling efficiency below the sculpture. In view of this, we propose a 3D sculpture mold device with a water circulation cooling structure. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a 3D sculpture mold device with a water circulation cooling structure to solve the technical problem that the current cooling pipe coverage cannot be adjusted, resulting in low cooling efficiency for large-sized sculptures.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a 3D sculpture mold device with a water circulation cooling structure, including a lower mold and an upper mold at the top of the lower mold, wherein mold cores are provided on the opposite surfaces of the lower mold and the upper mold; The lower mold includes a cooling mechanism, which includes a positioning rod, a first piston, and two linkage plates. The first piston is fixedly connected to the bottom surface of the positioning rod, and a drive plate is screwed to the top surface of the positioning rod. The two linkage plates are respectively rotatably installed on the outer walls of the two sides of the drive plate. The cooling mechanism also includes a cooling assembly, which includes a main cooling hole, two auxiliary cooling holes, and mounting holes at the bends of the auxiliary cooling holes. The main cooling hole and the two auxiliary cooling holes are all located inside the lower mold and the mold core. The cooling mechanism further includes an adjustment assembly, which includes a movable rod, a second piston, and a third piston. The third piston is fixedly connected to the bottom surface of the movable rod, and the second piston is fixedly connected to the outer wall of the movable rod. The second and third pistons are used to seal the auxiliary cooling holes.

[0006] Preferably, the cooling assembly further includes a liquid inlet pipe, which is threaded to the inner wall of the main cooling hole, with the liquid inlet end of the liquid inlet pipe facing the bottom surface; The cooling mechanism also includes a sleeve, which is threaded to the top surface of the liquid inlet pipe. The positioning rod is movably installed inside the sleeve. The first piston is located inside the liquid inlet pipe. A holding spring is sleeved on the outside of the positioning rod. The two ends of the holding spring are in contact with the top surface of the inner wall of the sleeve and the top surface of the outer wall of the first piston, respectively. The first piston is elastically connected to the inner wall of the sleeve through the holding spring. The first piston is used to block the bend of the liquid inlet pipe.

[0007] Preferably, a connecting plate is provided at the end of the linkage plate away from the drive plate, and the end of the connecting plate away from the linkage plate is screwed to the top surface of the movable rod. Mounting grooves for receiving the connecting plate are provided on both sides of the top surface of the lower mold. A sliding groove is provided on the connecting plate facing the outer wall of the linkage plate, and the linkage plate is slidably installed inside the sliding groove. A positioning shaft is movably installed inside the linkage plate. The end of the positioning shaft is threaded to the outer wall of the lower mold. The drive plate achieves lever drive of the connecting plate through the positioning shaft and the linkage plate.

[0008] Preferably, the main cooling holes and auxiliary cooling holes are arranged horizontally, with the two auxiliary cooling holes distributed on both sides of the main cooling holes. The main cooling holes and auxiliary cooling holes are connected. The main cooling holes inside the lower mold and the mold core form the main cooling channel, and the auxiliary cooling holes inside the lower mold and the mold core form the auxiliary cooling channel. The outer wall of the lower mold is provided with several cleaning holes, which are respectively connected to the main cooling channel and the auxiliary cooling channel. The cleaning holes are threaded with plugs at the external direction.

[0009] Preferably, the adjustment assembly further includes a positioning tube located outside the second piston and the third piston, and the positioning tube is fixedly connected inside the mounting hole.

[0010] Preferably, the second piston and the third piston are respectively distributed on the top and bottom surfaces of the auxiliary cooling hole, and the gap between the second piston and the third piston forms a coolant flow gap. A sealing ring for maintaining the seal between the positioning tube and the auxiliary cooling hole is fixedly connected to the outer wall of the tube. The sealing ring is in contact with the inner wall of the mounting hole. The outer wall of the sealing ring is provided with a circular array of through holes, and the size of the through holes is adapted to the inner diameter of the auxiliary cooling hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves flexible switching of the cooling coverage range by designing an adjustment mechanism consisting of a positioning rod, a linkage plate, a movable rod, and multiple pistons. When cooling small-sized sculptures, the first piston blocks the bend in the liquid inlet pipe, and the coolant circulates only in the main cooling channel to meet basic cooling requirements. When cooling large-sized sculptures, increasing the coolant input pressure can push the first piston upward, which in turn drives the movable rod downward through the linkage plate lever, releasing the blockage of the auxiliary cooling channel by the third piston. This allows the coolant to flow through both the main and auxiliary channels simultaneously, solving the problem of low cooling efficiency for large-sized sculptures due to the inability to adjust the coverage range of the cooling pipe.

[0012] 2. This utility model also features a design where the sealing ring on the outer wall of the positioning tube fits tightly against the inner wall of the mounting hole, preventing coolant from leaking out from the gap between the mounting hole and the positioning tube. Furthermore, the through hole on the sealing ring matches the inner diameter of the auxiliary cooling hole, ensuring normal coolant flow. The sleeve guides the movement of the positioning rod, and the positioning tube encloses and limits the movement of the second and third pistons, guaranteeing precise alignment when each piston moves. Both the main and auxiliary cooling holes are horizontally arranged inside the lower mold and mold core, with the two auxiliary cooling holes symmetrically distributed on both sides of the main cooling hole, forming a balanced cooling layout of "one main and two auxiliary." When the coolant flows within the channel, it can achieve comprehensive and uniform heat exchange with the mold core and internal sculpture, avoiding problems such as localized shrinkage and deformation of the sculpture and surface cracking caused by uneven cooling in traditional molds. This further solves the problem of the non-adjustable cooling coverage area. Attached Figure Description

Detailed Implementation

[0015] like Figures 1 to 9 As shown, this utility model relates to a 3D sculpture mold device with a water circulation cooling structure, including a lower mold 1 and an upper mold 11 at the top of the lower mold 1. Both the lower mold 1 and the upper mold 11 have mold cores 12 on their opposite surfaces. The lower mold 1 includes a cooling mechanism 2, which includes a positioning rod 22, a first piston 23, and two linkage plates 26. The first piston 23 is fixedly connected to the bottom surface of the positioning rod 22, and a drive plate 25 is screwed to the top surface of the positioning rod 22. The two linkage plates 26 are rotatably mounted on the outer walls of both sides of the drive plate 25. The cooling mechanism 2 also includes a cooling... The cooling component 3 includes a main cooling hole 31, two auxiliary cooling holes 32, and mounting holes 34 formed at the bends of the auxiliary cooling holes 32. The main cooling hole 31 and the two auxiliary cooling holes 32 are all located inside the lower mold 1 and the mold core 12. The cooling mechanism 2 also includes an adjustment component 4, which includes a movable rod 42, a second piston 43, and a third piston 44. The third piston 44 is fixedly connected to the bottom surface of the movable rod 42, and the second piston 43 is fixedly connected to the outer wall of the movable rod 42. The second piston 43 and the third piston 44 are used to seal the auxiliary cooling holes 32. The cooling range can be flexibly adjusted according to the size of the sculpture. For small sizes, the coolant only flows through the main cooling hole 31 to meet basic cooling needs. For large sizes, increasing the pressure activates the auxiliary cooling holes 32, expanding the coverage area and improving efficiency, while also ensuring uniform cooling and preventing sculpture deformation and cracking.

[0016] Specifically, the cooling assembly 3 also includes an inlet pipe 35, which is threaded to the inner wall of the main cooling hole 31. The inlet end of the inlet pipe 35 faces the bottom. The cooling mechanism 2 also includes a sleeve 21, which is threaded to the top surface of the inlet pipe 35. A positioning rod 22 is movably installed inside the sleeve 21. A first piston 23 is located inside the inlet pipe 35. A holding spring 24 is sleeved on the outside of the positioning rod 22. The two ends of the holding spring 24 are in contact with the top surface of the inner wall of the sleeve 21 and the top surface of the outer wall of the first piston 23, respectively. The first piston 23 is elastically connected to the inner wall of the sleeve 21 through the holding spring 24. The first piston 23 is used to block the bend of the inlet pipe 35. The threaded connection of the inlet pipe 35 facilitates installation and disassembly. When the inlet pipe 35 becomes blocked or damaged, it can be quickly replaced, reducing maintenance costs. The design of the inlet end facing the bottom allows the coolant to flow more smoothly into the main cooling hole 31, reducing flow resistance. The sleeve 21 provides a guide and positioning for the positioning rod 22, ensuring that the positioning rod 22 maintains vertical movement when it drives the first piston 23, ensuring the accuracy of the first piston 23's movement. The elastic connection design of the top spring 24 provides a continuous top force for the first piston 23, allowing the first piston 23 to stably block the bend of the inlet pipe 35 when there is no pressure. The first piston 23 only partially blocks the bend, ensuring the smooth flow of coolant from inside the inlet pipe 35 into the main cooling hole 31. At the same time, when the auxiliary cooling hole 32 needs to be opened, it can also be flexibly compressed under the action of increased coolant pressure, ensuring the controllability of coolant flow into the auxiliary cooling hole 32.

[0017] Furthermore, a connecting plate 46 is provided at the end of the linkage plate 26 away from the drive plate 25. The end of the connecting plate 46 away from the linkage plate 26 is screwed to the top surface of the movable rod 42. Mounting grooves 13 for accommodating the connecting plate 46 are provided on both sides of the top surface of the lower mold 1. A sliding groove is provided on the outer wall of the connecting plate 46 facing the linkage plate 26, and the linkage plate 26 is slidably installed inside the sliding groove. A positioning shaft 27 is movably installed inside the linkage plate 26. The end of the positioning shaft 27 is threaded to the outer wall of the lower mold 1. The drive plate 25 realizes the lever drive of the connecting plate 46 through the positioning shaft 27 and the linkage plate 26. The screw connection between the connecting plate 46 and the movable rod 42 facilitates their assembly and disassembly. When either the movable rod 42 or the connecting plate 46 malfunctions, they can be replaced individually, reducing maintenance costs. The mounting slot 13 can store the connecting plate 46 during operation, preventing it from being exposed and affecting the mold closing state of the lower mold 1 and the upper mold 11. The sliding groove on the connecting plate 46 and the sliding engagement with the linkage plate 26 can adapt to the position changes of the linkage plate 26 during the lever drive process, ensuring the continuity of power transmission and preventing mechanical jamming. The positioning shaft 27 not only provides a rotation fulcrum for the linkage plate 26, ensuring the stable realization of the lever drive, but its threaded connection also facilitates the installation and position adjustment of the positioning shaft 27, further improving the accuracy of the linkage plate 26's movement.

[0018] It is worth noting that the main cooling hole 31 and the auxiliary cooling hole 32 are arranged horizontally, with the two auxiliary cooling holes 32 distributed on both sides of the main cooling hole 31. The main cooling hole 31 and the auxiliary cooling hole 32 are connected. The main cooling hole 31 inside the lower mold 1 and the mold core 12 forms the main cooling channel, and the auxiliary cooling hole 32 inside the lower mold 1 and the mold core 12 forms the auxiliary cooling channel. Several cleaning holes 33 are opened on the outer wall of the lower mold 1. The cleaning holes 33 are connected to the main cooling channel and the auxiliary cooling channel respectively. The cleaning holes 33 are threaded with plugs at the external direction. The horizontal arrangement of the main cooling hole 31 and the auxiliary cooling hole 32 allows the coolant to be evenly distributed in the flow channel, ensuring cooling uniformity and avoiding localized insufficient cooling due to the tilt of the flow channel. The interconnected design of the main cooling flow channel and the auxiliary cooling flow channel realizes the diversion and merging of coolant. Depending on the size of the sculpture, it is possible to flexibly choose to use only the main cooling flow channel or to use both the main cooling flow channel and the auxiliary cooling flow channel at the same time, which improves the adaptability of the cooling system. The setting of the cleaning hole 33 facilitates the regular cleaning of the main cooling flow channel and the auxiliary cooling flow channel, preventing impurities in the coolant from accumulating and clogging the flow channel, ensuring the long-term stable operation of the cooling system. The plug can seal the cleaning hole 33 after cleaning to prevent coolant leakage.

[0019] It is worth mentioning that the adjustment assembly 4 also includes a positioning tube 41, which is located outside the second piston 43 and the third piston 44 and is fixedly connected inside the mounting hole 34. The positioning tube 41 provides a guide for the movement of the second piston 43 and the third piston 44, ensuring that they remain on the auxiliary cooling hole 32 during movement, thus improving the accuracy of the sealing. At the same time, the positioning tube 41 being fixed inside the mounting hole 34 also enhances the overall installation stability of the adjustment assembly 4, preventing the adjustment assembly 4 from shifting due to vibration during the cooling process.

[0020] It is worth noting that the second piston 43 and the third piston 44 are respectively distributed on the top and bottom surfaces of the auxiliary cooling hole 32. The gap between the second piston 43 and the third piston 44 forms a coolant flow gap. A sealing ring 45 for maintaining the seal between the positioning tube 41 and the auxiliary cooling hole 32 is fixedly connected to the outer wall. The sealing ring 45 contacts the inner wall of the mounting hole 34. The outer wall of the sealing ring 45 has a circular array of through holes, and the size of the through holes is adapted to the inner diameter of the auxiliary cooling hole 32. The distribution of the second piston 43 and the third piston 44 on the top and bottom surfaces of the auxiliary cooling hole 32 can seal the auxiliary cooling hole 32 from both top and bottom directions, ensuring the sealing effect. The gap between the two pistons forms a coolant flow gap, allowing the coolant to pass smoothly when the auxiliary cooling channel is needed, ensuring the cooling effect. The sealing ring 45 can effectively enhance the sealing between the positioning tube 41 and the auxiliary cooling hole 32, preventing coolant leakage from the gap between the mounting hole 34 and the positioning tube 41, ensuring the sealing of the cooling system. The through hole on the sealing ring 45 is matched with the inner diameter of the auxiliary cooling hole 32, ensuring that the coolant flows smoothly when passing through the sealing ring 45, further ensuring the normal operation of the cooling system.

[0021] Working Principle: This embodiment provides a 3D sculpture mold device with a water circulation cooling structure. During use, the need for auxiliary cooling channels is determined based on the size of the 3D sculpture to be cooled inside the mold core 12. When the sculpture size is small, only the main cooling channel needs to operate to meet the cooling requirements. The external coolant pumping device pumps the coolant normally. At this time, the top-holding spring 24 is in an extended state, and its two ends generate a holding force on the top surface of the inner wall of the sleeve 21 and the top surface of the outer wall of the first piston 23, respectively. This causes the first piston 23 to stably block the bend of the inlet pipe 35, only blocking half of it, ensuring that the coolant can enter the main cooling hole 31. The operator connects the coolant to the inlet end of the inlet pipe 35. The coolant flows along the inlet pipe 35. Due to the blocking effect of the first piston 23, the coolant... Coolant can only enter the main cooling hole 31, which forms the main cooling channel inside the lower mold 1 and the mold core 12. The coolant circulates in the main cooling channel and achieves initial cooling through heat exchange with the mold core 12 and the internal sculpture. The coolant that has completed heat exchange is finally discharged from the outlet of the main cooling channel. When the sculpture is large and the main cooling channel cannot meet the full cooling requirements, the main cooling channel and the auxiliary cooling channel need to be used at the same time. At this time, by increasing the input pressure of the coolant in the inlet pipe 35, the high-pressure coolant generates a downward thrust on the first piston 23. This thrust overcomes the holding force of the top spring 24, causing the first piston 23 to move upward along the inner wall of the inlet pipe 35. The upward movement of the first piston 23 drives the positioning rod 22, which is fixedly connected to it, to move upward synchronously. The positioning rod 22 then drives the drive plate 25, which is connected to the top screw, to move upward. When the drive plate 25 moves upward, the linkage plate 26, which is rotatably mounted on the outer walls of its two sides, rotates around the positioning shaft 27 as a fulcrum. The positioning shaft 27 is movably mounted inside the linkage plate 26 and its end is threaded to the outer wall of the lower mold 1, providing a stable rotation fulcrum for the linkage plate 26. Since the end of the linkage plate 26 away from the drive plate 25 is connected to the top screw of the movable rod 42 through the connecting plate 46, and the connecting plate 46 has a groove on its outer wall facing the linkage plate 26, the linkage plate 26 can slide in the groove. Therefore, the rotation of the linkage plate 26 is converted into a downward pulling force on the connecting plate 46. Under this force, the connecting plate 46 moves downward along the mounting grooves 13 opened on both sides of the top surface of the lower mold 1. The downward movement of piston 46 causes the movable rod 42 to move downward synchronously. When the movable rod 42 moves downward, the second piston 43, which is fixedly connected to its outer wall, and the third piston 44, which is fixedly connected to its bottom surface, also move downward. Originally, the third piston 44 blocked the auxiliary cooling hole 32. As the second piston 43 moves downward, the blocking state is released, realizing that the second piston 43 and the third piston 44 respectively block the upper and lower ends of the auxiliary cooling hole 32. Thus, the auxiliary cooling flow channel formed by the auxiliary cooling hole 32 inside the lower mold 1 and the mold core 12 is opened. At the same time, because the first piston 23 moves upward and no longer blocks the bend of the liquid inlet pipe 35, some coolant can enter the main cooling hole 31 through the liquid inlet pipe 35, while the other part of the coolant flows through the coolant flow gap between the second piston 43 and the third piston 44.Entering the auxiliary cooling hole 32, which connects to the main cooling hole 31, the coolant circulates simultaneously in both the main and auxiliary cooling channels, significantly expanding the cooling coverage area. This achieves efficient cooling through more comprehensive heat exchange with the large sculpture. During this process, the sealing ring 45, fixedly connected to the outer wall of the positioning tube 41, is in close contact with the inner wall of the mounting hole 34, effectively preventing coolant leakage from the gap between the mounting hole 34 and the positioning tube 41. The circular array of through holes on the outer wall of the sealing ring 45 ensures smooth flow of coolant within the auxiliary cooling channel. During use, if impurities accumulate in the main or auxiliary cooling channels, affecting coolant flow, the operator can unscrew the plug on the cleaning hole 33 on the outer wall of the lower mold 1 to clean the inside of the channel. After cleaning, the plug can be screwed back on to restore the normal cooling function of the device. Once the coolant pressure is restored, the holding spring 24 releases its force, driving the first piston 23 to reset. This, in turn, drives the second piston 43 and the third piston 44 to reset via the linkage plate 26 and connecting plate 46. The third piston 44 then re-seals the auxiliary cooling hole 32.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
