Description

Technical Field

[0001] The present invention relates to the technical field of casting molds, and specifically relates to an intelligent temperature-controlled casting mold. Background Technique

[0002] A casting mold refers to a solid material formed by pouring molten metal or plastic materials inside the mold and then cooling. After pouring, the casting mold usually adopts the methods of self-cooling and liquid-cooling contact for cooling. Such cooling methods cannot precisely meet the complex requirements of different casting materials for the mold temperature under different casting processes. Direct contact liquid-cooling also causes the internal material to not be compensated, resulting in casting defects such as shrinkage cavities and porosity, making it impossible for small castings produced to be formed normally.

[0003] The utility model with the publication number of CN217617603U discloses a casting mold for preventing casting defects. By adding a centrifugal force mechanism with a rotating mechanism, the rotating mechanism drives the casting mold to rotate at a high speed. When casting a casting, liquid metal is injected from the sprue of the mold. Under the die-casting action of the centrifugal force generated by the high-speed rotation, the liquid metal can be cooled and solidified in a state where the cavity is filled, so that the cavity of the casting is quickly filled, the casting is quickly formed, and due to the die-casting action of the centrifugal force on the liquid metal, the casting is fully compensated and the internal structure of the casting is more dense.

[0004] The utility model with the publication number of CN217595831U discloses a casting mold for the production of elevator pulleys. When it is necessary to cool the casting cavity, circulating cold water can be respectively input into the main cylinder and the auxiliary cylinder. The circulating cold water will flow outside the casting cavity, and the heat near the casting cavity formed by the lower die base and the upper die base can be taken away for rapid cooling. Thus, when controlling the temperature of the casting mold, the forming cavity area inside the casting mold can be quickly cooled, the temperature control time can be shortened, and it is more convenient to use.

[0005] However, the above-mentioned temperature-controlled casting molds still have the following problems in actual use: Although the temperature is reduced by injecting water into the mold, before the casting mold is cast, the mold at room temperature contacts the molten material, and due to the large temperature difference, it will cause material defects and also affect the service life of the mold. At the same time, during the forming process, the cooling liquid cannot be effectively controlled, and rapid cooling easily causes cracks in the internal material, affecting the forming accuracy.

[0006] Therefore, we propose an intelligent temperature-controlled casting mold to solve the problems mentioned above. Summary of the Invention

[0007] The object of the present invention is to provide an intelligent temperature-controlled casting mold. To solve the problem that the existing temperature control method is to use water injection in the mold to achieve cooling. However, before the casting mold is cast, the mold at room temperature contacts the molten material, and due to the large temperature difference, it will cause material defects and also affect the service life of the mold. At the same time, during the molding process, the cooling liquid cannot be effectively controlled, and rapid cooling is likely to cause cracks in the internal material, affecting the molding accuracy.

[0008] To achieve the above object, the present invention provides the following technical solution: An intelligent temperature-controlled casting mold, including a bearing base, and support columns fixedly installed at the four corners of the top surface of the bearing base, and a protective top plate is fixedly arranged at the top ends of the support columns;

[0009] It further includes: A cooling mechanism is fixedly arranged at the central position of the top surface of the bearing base, and the cooling mechanism includes a cooling frame, and the cooling frame is fixedly installed at the central position of the top surface of the bearing base;

[0010] Among them, preheating mechanisms are fixedly arranged on the left and right sides above the bearing base, and the preheating mechanisms include preheating frames, and the preheating frames are fixedly installed on the left and right sides of the top surface of the bearing base.

[0011] Preferably, the left and right sides of the top surface of the bearing base are fixedly connected to the bottom ends of the lifting side plates, and the top ends of the left and right lifting side plates are fixedly connected to the outer ends of the upper mold body, and through grooves are formed in the symmetrically arranged lifting side plates, and positioning brackets are fixedly arranged inside the through grooves.

[0012] Preferably, the upper ends of the positioning brackets penetrating through the symmetrically arranged lifting side plates are rotatably provided with guide gears through bearings, and guide racks are fixedly arranged on the outer sides of the upper ends of the left and right lifting side plates, and the guide racks are meshed with the guide gears.

[0013] Preferably, the lower sides of the symmetrically arranged positioning brackets are rotatably provided with driving rotating shafts through bearings, and the outer ends of the driving rotating shafts are meshed with the rotating shafts of the guide gears through a first sprocket mechanism. By driving the guide racks to descend through the lifting side plates, the meshed guide gears and driving rotating shafts rotate.

[0014] Preferably, the cooling mechanism includes a closed partition, and the closed partition is fixedly installed at the central position inside the cooling frame, and a cooling circulation pipe is fixedly arranged between the closed partition and the cooling frame, and a lower mold body is fixedly arranged inside the closed partition, so as to achieve cooling of the lower mold body through the cooling mechanism.

[0015] Preferably, the cooling mechanism includes a storage water tank, and the storage water tank is connected to the outer end of the cooling circulation pipe through a conveying pipe. The cooling circulation pipe is connected in a penetrating manner in the up and down distribution, and a temperature control module is installed on the top surface of the storage water tank to adjust the operation of the cooling mechanism.

[0016] Preferably, the preheating mechanism includes a driving rotating shaft, and the driving rotating shaft is rotatably arranged on the upper and lower sides inside the preheating frame through bearings. The middle part of the lower driving rotating shaft is meshed and connected to the inner end of the driving rotating shaft inside the lifting side plate through a bevel gear set.

[0017] Preferably, the preheating mechanism includes a driving rotating shaft, and the driving rotating shaft is rotatably arranged on the upper and lower sides inside the preheating frame through bearings. The middle part of the lower driving rotating shaft is meshed and connected to the inner end of the driving rotating shaft inside the lifting side plate through a bevel gear set.

[0018] Preferably, the front end of the upper driving rotating shaft included in the preheating mechanism is fixedly connected to the rotating shaft of the upper driving gear, so that the rotation directions of the upper and lower driving rotating shafts are opposite. The middle outer walls of the upper and lower driving rotating shafts are fixedly connected to the outer ends of the preheating turning plates, and preheating nozzles are fixedly arranged at equal distances on the outer sides of the symmetrically arranged preheating turning plates.

[0019] Preferably, the preheating turning plates included in the preheating mechanism are distributed in a way that they are offset inside and outside. The preheating turning plates in the initial state cover the inner sides of the upper die body and the lower die body through the preheating nozzles, so that when the upper die body descends, the upper and lower preheating turning plates are driven to turn outwards for storage to prevent affecting subsequent casting work.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: For this intelligent temperature-controlled casting mold, during the merging process of the upper die body and the lower die body, through the turning of the preheating mechanism, the cavities on the upper and lower sides are heated to avoid the problem that the large temperature difference with the material affects the service life. At the same time, the temperature control module separates the cooling circulation pipe and the lower die body through the partition plate of the cooling mechanism to avoid cracks caused by rapid cooling, and improves the accuracy of casting forming and the temperature control effect. The specific content is as follows:

[0021] 1. The lifting side plate drives the upper die body to move downward. The contracted lifting side plate drives the guiding rack to drive the engaged guiding gear to rotate, and the guiding gear drives the driving rotating shaft below the positioning bracket to rotate through the first sprocket mechanism, so as to drive the preheating mechanism to work during the merging process of the upper die body and the lower die body, avoiding the problem that the large temperature difference affects the service life.

[0022] 2. The driving rotating shaft rotates the transmission rotating shaft of the preheating mechanism through a bevel gear set, and the second sprocket mechanism drives the driving gear and the upper transmission rotating shaft to rotate. The transmission rotating shafts distributed on the upper and lower sides drive the preheating turnover plates to rotate outward in opposite directions, and heat the cavities of the upper die body and the lower die body during the rotation process to reduce the temperature difference between the molten material and the upper die body and the lower die body, avoiding difficult demolding in the subsequent process.

[0023] 3. The combined upper die body and the lower die body form the casting of the material through the cavity. At the same time, the temperature control module detects the temperature of the casting environment and drives the storage water tank of the cooling mechanism to inject water into the cooling circulation pipe inside the cooling frame, thereby realizing the heat dissipation-assisted forming with independent temperature control.

[0024] Furthermore, the cooling frame separates the cooling circulation pipe from the lower die body through the internal closed partition, so that the cooling circulation pipe assists the material to cool and solidify by wrapping, in order to improve the accuracy of the casting forming and the temperature control effect during the casting process.

[0039] The upper ends of the symmetrically arranged lifting side plates 6 passing through the positioning brackets 9 are rotatably arranged with guiding gears 10 through bearings, and guiding racks 11 are fixedly arranged on the outer sides of the upper ends of the left and right lifting side plates 6, and the guiding racks 11 are meshed with the guiding gears 10; the driving rotating shafts 12 are rotatably arranged through bearings below the symmetrically arranged positioning brackets 9, and the outer ends of the driving rotating shafts 12 are meshed with the rotating shafts of the guiding gears 10 through the first sprocket mechanism 13. By driving the guiding racks 11 to descend through the lifting side plates 6, the meshed guiding gears 10 and the driving rotating shafts 12 are rotated.

[0040] Such as Figures 5-6As shown in the figure, the lifting side plates 6 installed on the left and right sides of the top surface of the bearing base 1 are driven by lifting cylinders, so that the lifting side plates 6 drive the upper die body 7 fixedly connected to the top end to move downward. The descending lifting side plates 6 drive the guide racks 11 above the outside, and drive the engaged guide gears 10 to rotate at the top end of the positioning bracket 9. At the same time, the guide gears 10 drive the engaged drive rotating shafts 12 to rotate through the first sprocket mechanism 13 at the outer end, so as to drive the preheating mechanisms on the left and right sides to preheat and work during the descent of the upper die body 7.

[0041] Embodiment 2: In order to solve the problems existing in the use of the existing temperature-controlled casting mold, therefore, in this embodiment, through the following technical solutions, the preheating mechanism includes a transmission rotating shaft 20, and the transmission rotating shaft 20 is rotatably arranged inside the upper and lower sides of the preheating frame 5 through bearings. And the middle part of the lower transmission rotating shaft 20 is meshed and connected to the inner end of the drive rotating shaft 12 inside the lifting side plate 6 through a bevel gear set 24; the preheating mechanism includes a drive gear 21, and the drive gear 21 is rotatably arranged above the front end of the preheating frame 5 in an upper and lower meshing manner. And the rotating shaft of the lower drive gear 21 is meshed and connected to each other through a second sprocket mechanism 25 with the transmission rotating shaft 20 below the preheating frame 5.

[0042] The front end of the upper transmission rotating shaft 20 included in the preheating mechanism is fixedly connected to the rotating shaft of the upper drive gear 21, so that the rotation directions of the upper and lower transmission rotating shafts 20 are set to be opposite. And the outer walls of the middle parts of the upper and lower transmission rotating shafts 20 are fixedly connected to the outer ends of the preheating turning plates 22. And the preheating nozzles 23 are fixedly arranged at equal intervals on the outer sides of the symmetrically arranged preheating turning plates 22; the preheating turning plates 22 included in the preheating mechanism are distributed in a way of being offset inside and outside. And the preheating turning plates 22 in the initial state cover the inner sides of the upper die body 7 and the lower die body 16 through the preheating nozzles 23, so that the upper and lower preheating turning plates 22 are driven to turn outward for storage by the descent of the upper die body 7, in order to prevent affecting the subsequent casting work.

Then the transmission rotating shaft 20 drives the lower drive gear 21 to rotate through the second sprocket mechanism 25 at the front end, so as to drive the upper engaged drive gear 21 and the transmission rotating shaft 20 above the preheating frame 5 to rotate. The transmission rotating shafts 20 with opposite rotation directions on the upper and lower sides drive the fixedly connected preheating turning plates 22 to turn outward synchronously, and heat the cavities of the upper die body 7 and the lower die body 16 in contact through the preheating nozzles 23 outside the preheating turning plates 22, so as to reduce the temperature difference between the remaining molten materials and avoid damaging the upper die body 7 and the lower die body 16.

[0044] Embodiment 3: To solve the problems existing in the existing temperature-controlled casting molds during use, the following technical solutions are adopted in this embodiment. A cooling mechanism is fixedly arranged at the center position of the top surface of the bearing base 1, and the cooling mechanism includes a cooling frame 4, and the cooling frame 4 is fixedly installed at the center position of the top surface of the bearing base 1.

[0045] The cooling mechanism includes a closed partition 14, and the closed partition 14 is fixedly installed at the center position inside the cooling frame 4, and a cooling circulation pipe 15 is fixedly arranged between the closed partition 14 and the cooling frame 4, and a lower mold body 16 is fixedly arranged inside the closed partition 14, so as to cool the lower mold body 16 through the cooling mechanism. The cooling mechanism includes a storage water tank 17, and the storage water tank 17 is connected to the outer end of the cooling circulation pipe 15 through a conveying pipe 18, and the cooling circulation pipe 15 is arranged in a vertically penetrating connection, and a temperature control module 19 is installed on the top surface of the storage water tank 17 to adjust the operation of the cooling mechanism.

[0046] As Figures 2-5 shown, after the upper mold body 7 descends and merges with the lower mold body 16, the molten material is put in through the material port at the top of the upper mold body 7, so as to realize casting through the cavity between the upper mold body 7 and the lower mold body 16, and the temperature control module 19 installed above the bearing base 1 monitors the temperature of the casting environment during the casting process; and when auxiliary cooling is required, the storage water tank 17 is controlled to work, so as to convey the cooling water to the cooling circulation pipe 15 inside the cooling frame 4 through the conveying pipe 18. At the same time, the cooling frame 4 separates the cooling circulation pipe 15 from the lower mold body 16 through the internal closed partition 14, so that the cooling circulation pipe 15 assists the material to cool and solidify in a wrapping manner, so as to improve the precision of casting and the temperature control effect during the casting process.
