Description

Technical Field

[0001] This utility model relates to the field of box turning technology, and in particular to a V-process casting sand box turning frame. Background Technology

[0002] V-process casting uses a heated plastic film to seal and cover the sand mold. A vacuum pump is used to extract the air from the mold, creating a pressure difference between the inside and outside of the molding sand. This compacts the dry sand into shape, thus completing the casting process.

[0003] After the castings are formed inside the sand box, the sand box needs to be flipped to discharge the castings. When flipping the sand box, a connecting frame is usually installed on the outside of the sand box, and a drive mechanism is installed on the connecting frame to make the sand box rotate around the connection point of the connecting frame, thereby flipping the sand box. In order to ensure the stability of the connection between the connecting frame and the sand box, the connecting frame is usually not detachable. Although this can ensure the stability of the connection between the connecting frame and the sand box, it will affect the production of molding sand inside the sand box and the pouring of molten metal, thus having certain defects.

Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] This utility model provides, for example Figures 1-4 The image shows a V-process casting sand box turning frame.

[0045] Example 1: Includes a sand box 1, a crossbeam housing 2, an arm plate 3, a moving assembly, a mounting housing 5, a tilting assembly 6, and a locking unit. The crossbeam housing 2 is located on top of the sand box 1. The arm plate 3 is mounted on the bottom of the crossbeam housing 2 via the moving assembly. The mounting housing 5 is fixedly connected to the bottom of the arm plate 3. The tilting assembly 6 is installed inside the mounting housing 5. The moving assembly drives the arm plate 3 to slide at the bottom of the crossbeam housing 2, allowing the tilting assembly 6 to dock with and separate from the sand box 1. The crossbeam housing 2 is installed on a gantry for use, thereby enabling the sand box 1 to be lifted and moved. When the tilting assembly 6 docks with the sand box 1, the tilting assembly 6 can drive the sand box 1 to tilt. The locking unit is located inside the mounting housing 5 and is linked with the tilting assembly 6. That is, when the tilting assembly 6 tilts the sand box 1, the locking unit locks its connection point to prevent the tilting assembly 6 from separating from the sand box 1 when it tilts the sand box 1.

[0046] Furthermore, the moving component includes a connecting plate 41, a connecting seat 42, a drive screw 43, and a guide post 44. The connecting plate 41 is slidably installed inside the crossbeam housing 2. The connecting seat 42 is fixedly connected between the connecting plate 41 and the arm plate 3. A sliding hole is provided at the bottom of the crossbeam housing 2. The outer wall of the connecting seat 42 is slidably sleeved with the inner cavity of the sliding hole. The drive screw 43 is rotatably installed inside the crossbeam housing 2. The outer wall of the drive screw 43 is threadedly connected to the connecting plate 41. A motor for driving the drive screw 43 to rotate is installed inside the crossbeam housing 2. The motor drives the drive screw 43 to rotate, and the drive screw 43 can drive the connecting plate 41 to slide inside the crossbeam housing 2, thereby causing the connecting plate 41 to drive the arm plate 3 to move through the connecting seat 42. The guide post 44 is fixedly connected inside the crossbeam housing 2. The outer wall of the guide post 44 is slidably sleeved with the connecting plate 41. The guide post 44 can improve the stability of the connecting plate 41 sliding inside the crossbeam housing 2.

[0047] Example 2: Based on Example 1, the flipping assembly 6 includes a connecting sleeve 61, a connecting post 62, a driving disc 63, a driving sleeve 64, and a driving shaft 65. The connecting sleeve 61 is fixedly connected to the inside of the mounting housing 5. One end of the connecting post 62 is fixedly connected to the sand box 1, and the outer wall of the connecting post 62 is slidably sleeved with the connecting sleeve 61. The driving disc 63 is rotatably mounted on the outside of the connecting sleeve 61. The driving sleeve 64 is fixedly connected to one side of the driving disc 63. One end of the driving shaft 65 is fixedly connected to the sand box 1, and the outer wall of the driving shaft 65 is slidably sleeved with the driving sleeve 64. When the driving disc 63 rotates, the driving disc 63 can rotate around the connecting post 62 through the two driving sleeves 64 and the two driving shafts 65. The ends of the connecting post 62 and the driving shaft 65 are both hemispherical. The locking unit is used to limit the driving shaft 65 inside the driving sleeve 64.

[0048] Furthermore, the flipping assembly 6 also includes an internal gear ring 66 and a servo motor 67. The internal gear ring 66 is fixedly connected to one side of the drive disk 63, and the servo motor 67 is fixedly installed on one side of the mounting housing 5. The output end of the servo motor 67 is connected to a drive gear 68, which meshes with the internal gear ring 66. The servo motor 67 can drive the drive disk 63 to rotate through the drive gear 68 and the internal gear ring 66.

[0049] Furthermore, the flipping assembly 6 also includes a grating 69 and a protective housing. The grating 69 is installed on the inner wall of the mounting housing 5. A cursor that works with the grating 69 is fixedly installed on one side of the drive disk 63. The grating 69 and the cursor can identify the angle and orientation of the drive disk 63's rotation. The control program for the motor and servo motor 67 is existing technology and will not be described in detail here. The protective housing is fixedly connected to one side of the mounting housing 5 and is fitted over the outside of the servo motor 67.

[0050] Specifically, the locking unit includes an arc plate 7, a slot, and an annular groove. The arc plate 7 is symmetrically fixedly connected to the inside of the mounting housing 5. The slot is formed on the outside of the drive sleeve 64, and the inner cavity of the slot corresponds to the arc plate 7. The annular groove is formed on the outside of the drive shaft 65, and the annular groove corresponds to the arc plate 7. Figure 3 As shown, when the sand box 1 is vertically upward or vertically downward, the drive sleeve 64 on the drive disc 63 and the drive shaft 65 are on the same vertical line. At this time, the arc plate 7 does not contact the drive shaft 65, so that the sand box 1 can be separated from or connected to the flipping assembly 6. When the flipping assembly 6 drives the sand box 1 to flip, the arc plate 7 is engaged in the annular groove outside the drive shaft 65, thereby limiting the drive shaft 65 and preventing the sand box 1 from separating from the flipping assembly 6, thus improving its safety in use.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
