Description

Technical Field

[0001] This utility model belongs to the field of investment casting technology, and more specifically, it relates to a precision investment casting equipment. Background Technology

[0002] Investment casting, also known as lost-wax casting, mainly includes the following processes: wax pattern forming, tree assembly, slurry application, hardening, wax melting and shell making, melting and casting, and shell cleaning.

[0003] In the existing casting production process, most operations such as mold locking, wax injection, cooling, and casting need to be done manually, resulting in low work efficiency.

[0004] In the prior art, there are many inventions and designs concerning automated investment casting devices. For example, Chinese patent CN202210285520.6 discloses a precision investment casting equipment and its investment casting method. A control system controls an electric telescopic rod to move a connecting seat downwards, causing the connecting seat to contact the locking groove. At this time, an electromagnet is energized and becomes magnetic. The electromagnet and the corresponding surface of the magnetic locking block have opposite magnetic properties, thus connecting the mold body and the connecting seat into a whole through magnetic attraction. This method is convenient to operate and has a high degree of automation. Through the combined use of a rotating motor and an electric telescopic rod, the hardened mold body and wax model are inserted into a molten wax heating tank. The control system controls the heating wire to heat the mold body and wax model inside the hardened shell, melting them to obtain the casting mold. The molten wax enters a wax collection tank through an outlet pipe for easy recycling. However, this patent can only use one mold for processing at a time. Although the high degree of automation reduces labor costs, the production efficiency is still relatively low. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a precision investment casting equipment to solve the problem of low efficiency caused by existing investment casting equipment being able to use only one mold for production at a time.

[0006] This utility model provides a precision investment casting equipment, which is achieved by the following specific technical means:

[0007] A precision investment casting device includes a mounting base; the mounting base is arched, and there are two sets of mounting bases. Each mounting base is equipped with a downward-facing electric telescopic rod. The end of the electric telescopic rod is fixedly connected to a lifting plate. Multiple sets of lifting rods are fixedly connected below the lifting plate. Electromagnets A are fixedly connected to the lower ends of the lifting rods. Electromagnets B are attracted to the bottom of each electromagnet A. A mold is fixedly connected below the electromagnet B. A circular fixing plate is set below the mold. The fixing plate is equipped with a slurry tank, a hardener tank, a wax heating tank, a shelling tank, and a casting machine. A rotating mechanism is connected below the fixing plate. The rotating mechanism includes a circular track, and an equipment base is welded to the bottom of the circular track. The rotating mechanism is rotatably connected to a drive linkage. One end of the drive linkage is rotatably connected to a transmission disk. The transmission disk is connected above the rotating mechanism. Multiple sets of transmission wheels are rolled on the outer side of the transmission disk. The transmission wheels are fixedly connected to the shaft of a drive motor. The body of the drive motor is mounted and fixed to the side wall of the circular track and the equipment base through a motor mount.

[0008] Furthermore, the slurry bucket, hardener bucket, wax melting heating bucket, shelling bucket, and casting machine are arranged in a circle and fixed on a fixed plate, and are respectively located at the five corners of a plane regular hexagon, arranged in a counterclockwise order as follows: slurry bucket, hardener bucket, wax melting heating bucket, shelling bucket, and casting machine.

[0009] Furthermore, a connecting plate is provided inside the annular track, the connecting plate is fixed below the fixed plate, and a support rod is fixedly connected below the connecting plate, with a limiting member provided at the end of the support rod.

[0010] Furthermore, the limiting component includes an upper limit block, and a roller is installed on one side of the upper limit block. The roller is rotatably connected to a slide rail opened on the annular track.

[0011] Furthermore, the upper limit block has a placement hole at its bottom, in which a buffer spring is placed. One end of the buffer spring is connected to the lower limit block, and the lower limit block also has a placement hole at its top. The buffer spring is located in the placement holes of both the upper and lower limit blocks. A limit rod is provided above the lower limit block, and the limit rod slides through the upper limit block. A hemispherical pit is provided at the bottom of the lower limit block, in which a steel ball is placed. The steel ball rolls and connects to the annular groove on the annular track.

[0012] Furthermore, a drive rod is provided below the end of a support rod connected to the connecting plate, and a limiting plate is provided at the bottom of the drive rod. The drive rod is rotatably connected to a drive link through a bushing, and the bushing is equidistantly positioned on the drive link.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, after the drive motor is turned on, the transmission wheel drives the transmission disk to rotate. The drive linkage connected to the transmission disk at one end rotates and follows the transmission disk in a circular motion. It also drives multiple sets of rotating mechanisms to rotate simultaneously through the bushing and drive rod. Each rotation is one-sixth of a revolution. In conjunction with the electric telescopic rod, the mold is raised and lowered. First, the electromagnet A below the lifting rod is energized to attract the electromagnet B on the mold, and multiple sets of molds are lifted at the same time. All molds are then sequentially subjected to wax injection, slurry application, cooling and hardening, high-temperature wax melting, vibration demolding, and casting. The degree of automation is high, and most of the casting steps except for casting, cutting, and cut smoothing can be completed automatically, reducing the consumption of manpower and time, thereby reducing production costs.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 8 As shown:

[0028] This utility model provides a precision investment casting equipment, including a mounting base 1; the mounting base 1 is arched, and there are two sets of mounting bases 1. Each mounting base 1 is equipped with a downward-facing electric telescopic rod 2. The end of the electric telescopic rod 2 is fixedly connected to a lifting plate 3. Multiple sets of lifting rods 4 are fixedly connected below the lifting plate 3. Electromagnets A5 are fixedly connected to the lower end of each lifting rod 4. Electromagnets B6 are attracted to the bottom of each electromagnet A5 when energized. A mold 7 is fixedly connected below the electromagnet B6. A circular fixing plate 8 is set below the mold 7. A slurry tank 9, a hardener tank 10, and a molten wax heating tank 11 are set on the fixing plate 8. The shelling barrel 12 and the casting machine 13 are connected to a rotating mechanism below the fixed plate 8. The rotating mechanism includes a ring track 14, and an equipment base 15 is welded to the bottom of the ring track 14. The rotating mechanism is rotatably connected to a drive rod 16. One end of the drive rod 16 is rotatably connected to a transmission disk 17. The transmission disk 17 is connected above the rotating mechanism. Multiple sets of transmission wheels 18 are rolled on the outside of the transmission disk 17. The transmission wheels 18 are fixedly connected to the shaft of the drive motor 19. The body of the drive motor 19 is mounted and fixed to the side wall of the ring track 14 and the equipment base 15 through a motor base 20.

[0029] Among them, such as Figure 2As shown, the slurry tank 9, hardener tank 10, molten wax heating tank 11, shell removal tank 12, and casting machine 13 are arranged in a circle and fixed on the fixed plate 8, and are respectively located at the five corners of a plane regular hexagon. The order of arrangement in counterclockwise is: slurry tank 9, hardener tank 10, molten wax heating tank 11, shell removal tank 12, and casting machine 13. During production, the electric telescopic rod 2 cooperates with the drive motor 19 to sequentially inject wax, slurry, cool and harden, melt wax at high temperature, melt and cast, vibrate to remove shell, and pour the mold. The degree of automation is high, and it can automatically complete most of the melting and casting steps except for pouring, cutting, and cutting edge smoothing, which reduces manpower consumption and thus reduces production costs.

[0030] Among them, such as Figure 4 As shown, a connecting plate 21 is provided inside the annular track 14. The connecting plate 21 is fixed below the fixed plate 8. A support rod 22 is fixedly connected below the connecting plate 21, and a limiting member is provided at the end of the support rod 22; Figure 6 As shown, the limiting component includes an upper limit block 23, and a roller 24 is installed on one side of the upper limit block 23. The roller 24 is tactilely connected to the slide rail opened on the annular track 14. The roller 24 is limited in the slide groove of the annular track 14, which improves the roundness of the rotating mechanism when it rotates, ensures that the rotating mechanism runs smoothly when the fixed plate 8 is driven to rotate, and avoids the annular track 14 from being deformed under high load.

[0031] Among them, such as Figure 6 As shown, the upper limit block 23 has a placement hole at its bottom, in which a buffer spring 25 is placed. One end of the buffer spring 25 is connected to the lower limit block 26, and the lower limit block 26 also has a placement hole at its top. The buffer spring 25 is located in the placement holes of both the upper limit block 23 and the lower limit block 26. A limit rod 27 is provided above the lower limit block 26, and the limit rod 27 slides through the upper limit block 23. A hemispherical pit is provided at the bottom of the lower limit block 26, in which a steel ball 28 is placed. The steel ball 28 is rolled in the annular groove on the annular track 14. The steel ball 28 rolls in the annular groove of the annular track 14, reducing the friction force on the rotating mechanism during rotation, thereby reducing the torque required by the drive motor 19 during operation and extending the service life of the equipment.

[0032] Among them, such as Figure 8As shown, a support rod 22 connected to the connecting plate 21 has a drive rod 29 near its end. A limiting plate 30 is provided at the bottom of the drive rod 29. The drive rod 29 is rotatably connected to a drive link 16 through a bushing 31. The bushing 31 is equidistantly positioned on the drive link 16. After the drive motor 19 is turned on, the transmission wheel 18 drives the transmission disk 17 to rotate. The drive link 16, which is rotatably connected to the transmission disk 17 at one end, follows the transmission disk 17 in a circular motion. It also drives multiple sets of rotating mechanisms to rotate simultaneously through the bushing 31 and the drive rod 29. Each rotation is one-sixth of a revolution. In conjunction with the electric telescopic rod 2, the mold 7 is raised and lowered, so that multiple investment molds 7 can be used for processing and production at the same time.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In this utility model, after the drive motor 19 is turned on, the transmission wheel 18 drives the transmission disk 17 to rotate. The drive linkage 16, which is rotatably connected to the transmission disk 17, follows the transmission disk 17 to make a circular motion. It also drives multiple sets of rotating mechanisms to rotate simultaneously through the bushing 31 and the drive rod 29. Each rotation is one-sixth of a revolution. In conjunction with the electric telescopic rod 2, the mold 7 is raised and lowered. First, the electromagnet A5 below the lifting rod 4 is energized to attract the electromagnet B6 on the mold 7. At the same time, multiple sets of molds 7 are lifted. The wax injection, slurry dipping, cooling and hardening, high-temperature wax melting, melting and casting, vibration shelling, and casting steps are completed for all molds 7 in sequence.

[0035] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
