Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold release agent technology, and in particular to a mold release agent preheating device. Background Technology
[0002] In the field of metal casting and stamping, release agent is a chemical substance or mixture specifically used to form an isolation layer between the mold and the metal forming material. Its main function is to prevent the metal material from adhering to the mold surface during the stamping process, thereby ensuring that the workpiece can be demolded smoothly, reducing friction and wear between the mold and the workpiece, and avoiding damage to the mold and the surface of the finished product. There are many types of release agents, including liquid release agents.
[0003] When liquid release agent is sprayed, the surface of the mold is always under a high temperature gradient, but the temperature of the release agent is relatively low. This results in a large temperature difference between the release agent and the mold, which may cause the release agent to not adhere evenly to the mold surface and not effectively protect the mold and the product for smooth demolding. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an apparatus to solve one or more problems in the prior art.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A mold release agent preheating device includes a tank. A feed pipe is fixedly connected to the top of the tank, and a discharge pipe is fixedly connected to one side of the tank at its bottom. A valve is provided on the outer side of the discharge pipe. A disc-type heat exchange tube is fixedly connected to the inner wall of the tank. A circular shaft is rotatably connected to the inner bottom wall of the tank via a bearing. A slip ring that moves axially along the circular shaft is provided on the outer side of the shaft. Multiple evenly distributed connecting posts are fixedly connected to the outer side of the slip ring. A fixing ring is fixedly connected to one end of each connecting post. A spiral strip is sleeved on each connecting post, and both ends of the spiral strip are fixed to the slip ring and the fixing ring, respectively. A power component for rotating the circular shaft is provided on the outer top wall of the tank, and a drive assembly for reciprocating up and down movement of the slip ring is provided inside the tank.
[0007] As a further embodiment of this utility model, the power component is a geared motor, which is fixedly connected to the top outer wall of the tank. One end of the output shaft of the geared motor passes through the tank and is fixed to a round shaft via a coupling.
[0008] As a further embodiment of this utility model, the drive assembly includes two connecting plates, which are symmetrically fixedly connected to both sides of a circular shaft. Each of the two connecting plates has a mounting hole at its top. A threaded rod is rotatably connected to the mounting hole via a bearing, and the threaded rod passes through a fixed ring and is threadedly connected to the fixed ring. A gear is keyed to the top of the threaded rod, and a gear ring is fixedly connected to the inner wall of the top of the tank, with the gear meshing with the gear ring.
[0009] As a further embodiment of this utility model, scrapers that fit against the inner wall of the tank are fixedly connected to one side of each of the two connecting plates in opposite directions.
[0010] As a further embodiment of this utility model, one end of the disc heat exchanger tube is fixedly connected to a water inlet pipe, and the other end of the disc heat exchanger tube is fixedly connected to a water outlet pipe, both of which extend out of the tank body.
[0011] As a further embodiment of this utility model, the bottom end of the threaded rod is provided with a groove, and a ball bearing that rolls and contacts the inner wall of the bottom of the tank is rolled in the groove.
[0012] As a further embodiment of this utility model, a sealing cap is snapped onto the top end of the feed pipe, and a sealing ring is provided between the sealing cap and the feed pipe.
[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0014] 1. By setting up a disc heat exchange tube, hot fluid is added into the disc heat exchange tube through the water inlet pipe. The hot fluid flows in the disc heat exchange tube to exchange heat with the liquid release agent in the tank, thereby heating the liquid release agent. This avoids a large temperature difference between the liquid release agent and the mold, and solves the problem that the release agent cannot be evenly attached to the mold surface and cannot effectively protect the mold and the product for smooth demolding.
[0015] 2. Through the configuration of the drive component, the drive component can drive the slip ring to move up and down along the axial direction of the circular shaft through the fixed ring, thereby agitating the liquid release agent with the fixed ring, so that the liquid release agent is heated evenly, thus improving the heating efficiency of the liquid release agent.

[0022] Reference Figures 1-3 A preheating device for a release agent includes a tank 1. An inlet pipe 4 is welded to the top of the tank 1, and an outlet pipe 6 is welded to the bottom of one side of the tank 1. A valve is provided on the outside of the outlet pipe 6. A disc heat exchange tube 8 is bolted to the interlayer of the tank wall of the tank 1. A water inlet pipe 5 is welded to one end of the disc heat exchange tube 8, and a water outlet pipe 7 is welded to the other end of the disc heat exchange tube 8. Both the water inlet pipe 5 and the water outlet pipe 7 extend out of the tank 1. Hot fluid is added into the disc heat exchange tube 8 through the water inlet pipe 5. The hot fluid flows in the disc heat exchange tube 8 and is discharged through the water outlet pipe 7. During the flow of the hot fluid, heat exchange occurs on the liquid release agent in the tank 1, thereby heating the liquid release agent. This avoids a large temperature difference between the liquid release agent and the mold, and solves the problem that the release agent cannot adhere evenly to the mold surface and cannot effectively protect the mold and the product for smooth demolding.
[0023] In this utility model, the bottom inner wall of the tank body 1 is rotatably connected to a circular shaft 9 via a bearing. A slip ring 13 that moves along the axial direction of the circular shaft 9 is provided on the outer side of the circular shaft 9. Multiple evenly distributed connecting posts 19 are welded to the outer side of the slip ring 13. A fixing ring 17 is welded to one end of the connecting post 19. A spiral strip 18 is sleeved on the connecting post 19, and the two ends of the spiral strip 18 are fixed to the slip ring 13 and the fixing ring 17 respectively. The top outer wall of the tank body 1 is provided with a power component that makes the circular shaft 9 rotate. The power component is a geared motor 2. The geared motor 2 can be a DC motor and can rotate in both directions. The geared motor 2 is fixed to the top outer wall of the tank body 1 by bolts. One end of the output shaft of the geared motor 2 passes through the tank body 1 and is fixed to the circular shaft 9 via a coupling.
[0024] In particular, the tank body 1 is equipped with a drive assembly that enables the slip ring 13 to move up and down reciprocally. The drive assembly includes two connecting plates 15, which are symmetrically welded to both sides of the round shaft 9. Each connecting plate 15 has a mounting hole at its top. A threaded rod 12 is rotatably connected to the mounting hole via a bearing. The threaded rod 12 passes through a fixed ring 17 and is threadedly connected to the fixed ring 17. A gear 16 is keyed to the top of the threaded rod 12. A gear ring 10 is bolted to the inner wall of the top of the tank body 1, and the gear 16 meshes with the gear ring 10.
[0025] When the geared motor 2 is started, it rotates in both directions. The geared motor 2 drives the circular shaft 9 to rotate in both directions. During the rotation of the circular shaft 9, the gear 16 and the gear ring 10 mesh. The rotation of the gear 16 drives the threaded rod 12 to rotate. During the rotation of the threaded rod 12, the threaded rod 12 meshes with the fixed ring 17 through the threaded engagement, causing the fixed ring 17 to drive the slip ring 13 to move up and down along the axial direction of the circular shaft 9 through the connecting column 19. This causes the fixed ring 17 and the slip ring 13 to agitate the liquid release agent. At the same time, the spiral strip 18 turbulents the agitated release agent, thus performing multiple agitation and turbulence on the release agent, so that the liquid release agent is heated evenly, improving the heating efficiency of the liquid release agent.
[0026] It should be noted that scrapers 11 that fit against the inner wall of the tank 1 are welded to the opposite sides of the two connecting plates 15. During the rotation of the circular shaft 9, the scrapers 11 will be rotated through the connecting plates 15, thereby scraping and cleaning the inner wall of the tank 1 by the scrapers 11, preventing the liquid release agent from adhering to the inner wall of the tank 1. The bottom end of the threaded rod 12 is provided with a groove, and a ball bearing 20 that rolls in contact with the bottom inner wall of the tank 1 is connected in the groove. The ball bearing 20 will support the threaded rod 12, and at the same time, the ball bearing 20 will roll during the rotation of the threaded rod 12, thereby reducing the friction of the rotation of the threaded rod 12.
[0027] A sealing cap 3 is snapped onto the top of the feed pipe 4. A sealing ring is provided between the sealing cap 3 and the feed pipe 4. After the liquid release agent is added, the feed pipe 4 is sealed by the sealing cap 3, which can reduce the heat loss in the tank 1.
[0028] Working principle: During use, the liquid release agent is added into the tank 1 through the feed pipe 4, and at the same time, the hot fluid is added into the disc heat exchange tube 8 through the water inlet pipe 5. The hot fluid flows in the disc heat exchange tube 8 and is discharged through the water outlet pipe 7. During the flow of the hot fluid, heat exchange is carried out on the liquid release agent in the tank 1, thereby heating the liquid release agent and avoiding a large temperature difference between the liquid release agent and the mold. This solves the problem that the release agent cannot be evenly attached to the mold surface and cannot effectively protect the mold and the product for smooth demolding.
[0029] Simultaneously, the reduction motor 2 is started to rotate in both directions. The reduction motor 2 drives the circular shaft 9 to rotate in both directions. During the rotation of the circular shaft 9, the gear 16 and the gear ring 10 are engaged. The rotation of the gear 16 drives the threaded rod 12 to rotate. During the rotation of the threaded rod 12, the threaded engagement between the threaded rod 12 and the fixed ring 17 causes the fixed ring 17 to drive the slip ring 13 to move up and down along the axial direction of the circular shaft 9 through the connecting column 19. At the same time, the spiral strip 18 is rotated back and forth, thereby agitating the liquid release agent with the fixed ring 17 and the slip ring 13. The spiral strip 18 turbulents the agitated release agent, thereby agitating and turbulent the release agent multiple times, so that the liquid release agent is heated evenly and the heating efficiency of the liquid release agent is improved.
[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
