[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a casting and curing equipment for voltage transformer production provided in this embodiment includes a circulating mold clamping mechanism 1, which is used for mold joining and separation operations; the circulating mold clamping mechanism 1 includes a first support 101, and a circular frame 102 is rotatably connected to the first support 101, and the circular frame 102 includes a bottom plate 1021 and a top plate 1022, and a plurality of mold clamping assemblies 103 are arranged between the bottom plate 1021 and the top plate 1022.

One end of the guide rod 1033 is connected to the top plate 1022, and the other end of the guide rod 1033 is connected to the bottom plate 1021. The guide rod 1033 is used to install the upper mold 1031 and provide a motion guide for the upper mold 1031 so that the upper mold 1031 can be moved. 031 is precisely docked with the lower mold 1032, a first spring 1034 is sleeved on the guide rod 1033, the first spring 1034 is located between the upper mold 1031 and the bottom plate 1021, the first spring 1034 is used for the reset operation of the upper mold 1031, and a lower pressure column 1035 for pushing the upper mold 1031 downward is penetrated by the top plate 1022, the lower pressure column 1035 is slidably connected to the top plate 1022, and first balls 1036 are embedded at both ends of the lower pressure column 1035.

[0032] The circulating mold clamping mechanism 1 also includes a pressing assembly 104 for pushing the pressing column 1035 downward, and the pressing assembly 104 includes a second support 1041.

The pouring mechanism 2 includes a storage box 21 and a connecting pipe 22. The storage box 21 is fixed on the extrusion frame 1042, and the lower end of the storage box 21 is rotatably connected to the connecting pipe 22. A plurality of pouring tubes 23 that match the mold clamping assembly 103 are fixedly connected to the bottom plate 1021. In this embodiment, the number of pouring tubes 23 is eight, which is adapted to the number of the mold clamping assembly 103. One end of the pouring tube 23 is connected to the connecting pipe 22, and the other end of the pouring tube 23 is connected to a connecting piece 24. The connecting piece 24 is fixedly connected to the bottom plate 1021, and the connecting piece 24 is connected to the lower mold 1032 through a material guide pipe 25. A pouring plug 26 is provided through the connecting piece 24 and the two are slidably connected. A material guide hole 27 is provided on the pouring plug 26. When the material guide hole 27 is connected with the connecting piece 24, the connection operation among the pouring pipe 23, the connecting piece 24 and the material guide pipe 25 is realized, and then the pouring raw materials in the storage box 21 are introduced into the mold for pouring.

The upper end of the pouring plug 26 is connected with a pressing rod 210 that cooperates with the extrusion frame 1042, and a second ball 211 is embedded on the upper side of the pressing rod 210. The second ball 211 and the pressing rod 210 can be fixedly connected or movably connected. Preferably, the movably connected connection reduces friction.

[0034] like Figure 1 , Fig.10 , Fig.11 , Fig.12As shown, it also includes a placing and taking mechanism 4 that cooperates with the circulating mold clamping mechanism 1, and the placing and taking mechanism 4 includes a third support 41, and the upper side of the third support 41 is connected to a supporting platform 42, and the supporting platform 42 is connected to a track block 43, and a guide groove 44 is provided on the track block 43, and a track rod 45 is slidably connected in the guide groove 44, and both ends of the track rod 45 are connected to a lifting block 46, and one side of the lifting block 46 is connected to a clamping member 47, and the two clamping members 47 are symmetrically arranged, and a plurality of vacuum suction cups 48 are connected to the clamping member 47. In this embodiment, each clamping member 47 is respectively connected to three vacuum suction cups 48, and a sliding shaft 49 is penetrated through the lifting block 46. The moving shaft 49 is slidably connected to the lifting block 46, and both ends of the sliding shaft 49 are connected with sliding sleeves 410. A transverse column 411 is inserted in the sliding sleeve 410 and the two are slidably connected. The two ends of the transverse column 411 are respectively fixedly connected to the two sides of the track block 43. The upper side of the track block 43 is slidably connected with a driving block 412 for pushing the sliding sleeve 410 to slide. The track block 43 is connected to an electric push rod 413, and the output end of the electric push rod 413 is connected to the driving block 412. The two clamping members 47 and the two vacuum suction cups 48 have different functions. One realizes the operation of placing the internal components of the voltage transformer into the mold, and the other realizes the operation of taking out the finished voltage transformer.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a plurality of central shafts 5 are provided on the bottom plate 1021. In the present embodiment, the number of central shafts 5 is eight and is adapted to the clamping assembly 103. The central shaft 5 is slidably connected to the bottom plate 1021 and the central shaft 5 passes through the upper die 1031 and the lower die 1032. The upper die 1031 and the lower die 1032 are slidably connected to the central shaft 5 respectively. A third ball 6 is embedded at the lower end of the central shaft 5. A third spring 7 is sleeved on the central shaft 5. The upper end of the third spring 7 is fixedly connected to the lower side of the bottom plate 1021 and the lower end of the third spring 7 is fixedly connected to the central shaft 5. Both ends of the lower side of the extrusion frame 1042 are connected with second guide inclined plates 8 for extruding the central shaft 5. During the pouring process, the central shaft 5 passes through the upper die 1031 and the lower die 1032 to position the upper die 1031 and the lower die 1032. The central shaft 5 is tightly fitted to the inner edges of the upper die 1031 and the lower die 1032 to seal during the pouring process.

[0036] like Figure 1 , Fig. 9 As shown, a driving mechanism 3 for driving the circular ring frame 102 to rotate is provided on the first support 101, and the driving mechanism 3 includes a connecting plate 31, one end of the connecting plate 31 is connected to the first support 101, a motor 32 is installed on the connecting plate 31, a gear 33 is sleeved on the output end of the motor 32, and a gear ring 34 meshing with the gear 33 is coaxially connected to the lower side of the base plate 1021. The driving mechanism 3 can also be replaced by an existing well-known grooved wheel intermittent mechanism to achieve intermittent rotation.

[0037] like Figure 8 As shown, one side of the connecting piece 24 is connected to the limiting seat 9, and a limiting groove 10 is provided on the limiting seat 9. A limiting column 11 is slidably connected in the limiting groove 10, and one end of the limiting column 11 is fixedly connected to the casting plug 26. The limiting seat 9 and the limiting groove 10 limit the stroke of the limiting column 11, thereby limiting the stroke of the casting plug 26 to prevent the casting plug 26 from detaching from the connecting piece 24.

[0038] The working principle of this embodiment is as follows:

[0039] Step 1: Place the internal components of the voltage transformer on the supporting platform 42, the vacuum suction cup 48 adsorbs the internal components, and the electric push rod 413 is operated to move. The electric push rod 413 drives the driving block 412 to slide, and the driving block 412 pushes the sliding sleeve 410 connected to it to slide on the transverse column 411. The sliding sleeve 410 drives the sliding shaft 49 to move, and the two sliding shafts 49 drive the track rod 45 to slide in the guide groove 44, thereby realizing the movement of the clamping member 47 along the track of the guide groove 44. When the internal components move to the position of the lower mold 1032, the vacuum suction cup 48 places the internal components into the lower mold 1032.

[0040] Step 2: The motor 32 is operated to rotate, and the motor 32 drives the gear 33 to rotate, and the gear 33 drives the gear ring 34 to rotate, thereby realizing the rotation of the annular frame 102. The rotation of the annular frame 102 drives the upper mold 1031, the lower mold 1032, the guide rod 1033, the internal components, the lower pressure column 1035, the lower pressure rod 210, and the central axis 5 to rotate. The first ball 1036 at the upper end of the lower pressure column 1035 contacts and moves relative to the first guide inclined plate 1043, providing a downward pressure force to the lower pressure column 1035, and the lower pressure column 1035 drives the upper mold 1031 to move downward. At this time, the first spring 1034 is in a compressed state. After the first ball 1036 moves to contact with the extrusion frame 1042, the upper mold 1031 and the lower mold 1032 are fully engaged. When the ball 1036 contacts the first guide ramp 1043, the second ball 211 also contacts the first guide plate. The first guide ramp 1043 and the extrusion frame 1042 provide a force on the downward pressing rod 210, so that the downward pressing rod 210 drives the pouring plug 26 to move downward, and the guide hole 27 on the pouring plug 26 is connected with the connecting piece 24, so that the pouring tube 23, the connecting piece 24, and the guide tube 25 are connected, and the pouring raw material flows out of the storage box 21 and flows into the mold through the guide tube 25 to realize pouring; when the first ball 1036 contacts the first guide ramp 1043, the third ball 6 contacts the second guide ramp 8, and the central axis 5 moves upward into the center of the upper mold 1031 and the lower mold 1032, which plays a positioning and sealing role for both.

[0041] Step three: After the pouring is completed, the circular frame 102 continues to rotate. Due to the action of the first spring 1034, the second spring 28, and the third spring 7, the upper mold 1031 moves up and separates from the lower mold 1032 to realize the mold opening operation. The pouring plug 26 moves up to separate the material guide hole 27 from the connecting piece 24 to realize the pouring raw material blocking operation. The central axis 5 moves down and separates from the upper mold 1031 and the lower mold 1032 to reset. When the finished product moves to the position of the pick-up and placement mechanism, the vacuum suction cup 48 and the clamping member 47 take out the finished voltage transformer and place it on the supporting platform 42.

[0042] The circulating mold clamping mechanism 1 cooperates with the pick-and-place mechanism. In the integrated production process, the pick-and-place operations are performed simultaneously. The motor 32 rotates intermittently and cooperates with the electric push rod 413 to realize the pick-and-place operations.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
