Description

Technical Field

[0001] The utility model relates to the technical field of axial castings, in particular to an axial casting mould. Background Art

[0002] At present, the axis is the core part of the metal part, which generally plays the role of supporting and rotating the parts. Generally, the metal liquid is poured into the mold, cooled and formed, and then the axis is taken out to complete the manufacturing of the axis.

[0003] In the existing technology, after the axis is formed, external force is required to remove the axis. When the mold is opened, the mold is easily bumped, which affects the tightness of the axis, thereby increasing the defective rate of the finished product. At present, there is a lack of an axis removal mechanism inside the mold to ensure the rapid removal of the axis after completion and to ensure the quality of the axis. In order to solve the above problems, we propose an axis casting mold. Utility Model Content

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The utility model embodiment discloses an axial casting mold.

[0023] The utility model provides Figure 1-3 The axial casting mold shown includes a machine base 1, a left frame 2 is welded to the left side of the top of the machine base 1, and a right frame 6 is welded to the right side of the top of the machine base 1, a first cylinder 3 is installed on the outer wall of the left frame 2, a piston rod of the first cylinder 3 penetrates the inner wall of the left frame 2, and a left mold 4 is fixed to the end of the piston rod of the first cylinder 3, a second cylinder 7 is installed on the outer wall of the right frame 6, a piston rod of the second cylinder 7 penetrates the inner wall of the right frame 6, and a right mold 8 is fixed to the end of the piston rod of the second cylinder 7, and the bottom of the inner part of the machine base 1 A third cylinder 15 is installed in the middle of the base 1, and a mold support sleeve 11 is provided in the middle of the top of the base 1. A molding support groove 13 is provided inside the mold support sleeve 11, and a push block 12 is built in the molding support groove 13. The inner walls of the left mold 4 and the right mold 8 are both provided with molding grooves 10. The molding support sleeve 11 is installed on the mold. When the axis is cooled and formed, it will be vertically limited before the mold is opened, so that when the axis is demolded and taken out, it will be conducive to the rapid and complete removal of the axis, thereby ensuring the rapid demolding of the axis and ensuring the quality of the molded axis.

[0024] In order to quickly disassemble the drive shaft: Figure 1 and Figure 2 As shown, the end of the piston rod of the third cylinder 15 passes through the forming support groove 13 in the mold support sleeve 11, and the end of the piston rod of the third cylinder 15 is fixed to the central axis of the bottom end of the push block 12. When the third cylinder 15 is working, it will drive the push block 12 to rise and fall based on the inside of the forming support groove 13.

[0025] In order to provide better protection for the axis during demoulding: Figure 1 and Figure 2As shown, the push block 12 is adapted to the outer ring size of the forming support groove 13, and the push block 12 and the forming support groove 13 constitute a sliding mechanism. The forming support groove 13 is located directly below the forming groove 10, and the diameter of the forming support groove 13 is adapted to the diameter of the forming groove 10. When the push block 12 is located in the forming support groove 13 and is lifted and lowered, it will be beneficial to directly push the bottom of the forming axis to move, thereby driving the forming axis to fall off quickly, which greatly improves the efficiency of demolding after the axis is formed.

[0026] In order to ensure the quality of shaft production: Figure 1 As shown, both ends of the side wall of the left mold 4 are provided with mold docking holes 5, and both ends of the side wall of the right mold 8 are fixed with mold docking rods 9, the mold docking rods 9 are adapted to be docked with the mold docking holes 5, and the ends of the mold docking rods 9 are inserted into the inside of the mold docking holes 5. The mold docking rods 9 and the mold docking holes 5 are respectively provided on the left mold 4 and the right mold 8, so that when the left mold 4 and the right mold 8 are docked, the stability of the mold docking point will be guaranteed, thereby ensuring the quality of the internal axis during forming.

[0027] To control the operation of the device: Figure 1 , Figure 2 and Figure 3 As shown, a switch 14 is provided on the right side of the top of the base 1 , and the switch 14 is electrically connected to the first cylinder 3 , the second cylinder 7 and the third cylinder 15 , and the switch 14 will control the normal start and stop of the first cylinder 3 , the second cylinder 7 and the third cylinder 15 .

[0028] During operation, the left mold 4, the right mold 8 and the mold support sleeve 11 are connected to each other, the left mold 4 and the right mold 8 are fitted together, the mold docking rod 9 is inserted into the mold docking hole 5, and the bottom ends of the left mold 4 and the right mold 8 will fit together at the bottom end of the mold support sleeve 11, and the molten metal is poured into the connection between the left mold 4 and the right mold 8. At this time, the molten metal will be formed inside the forming support groove 13 and the forming groove 10 to form an axis. After the axis is cooled and formed, when the axis needs to be taken out, the switch 14 controls the first cylinder 3 and the second cylinder 7. The first cylinder 3 and the second cylinder 7 will respectively drive the left mold 4 and the right mold 8 to separate and open. At this time, the mold outside the axis is directly separated quickly. At this time, the axis will be inserted into the mold support sleeve 11. The switch 14 controls the third cylinder 15 to work. The third cylinder 15 will push the push block 12 up and down, so that the push block 12 drives the forming axis to move out of the outside of the mold support sleeve 11, thereby forming a quick demolding and ensuring the quality of the forming axis. The design is simple and more practical.
