Description

Technical Field

[0001] The invention relates to the field of processing molds, and in particular to a mold for processing a coupling which is easy to disassemble. Background Art

[0002] Couplings are an important component of mechanical transmission systems and are often used to connect two shafts or a shaft and a rotating part to transmit torque and motion. Couplings are mechanical parts used to connect two shafts (driving shaft and driven shaft) in different structures so that they rotate together to transmit torque. Casting is a common coupling processing method. During the coupling processing, liquid metal needs to be injected into the coupling mold through a mold. After the metal solidifies, subsequent processing is carried out to finally obtain the finished product.

[0003] The existing coupling casting mold still has the following problems when in use: During the existing coupling casting process, the upper and lower molds need to be fixed together, and liquid metal is injected into the interior of the two molds through the reserved casting port. After the liquid metal solidifies, the upper and lower molds are disassembled and the formed coupling is taken out. However, when connecting the two molds together, in order to ensure the tightness of the connection between the two molds, multiple sets of screws and nuts are usually used to fix the two molds together. This results in the need to turn the screws during the installation and disassembly process of the two molds before the two molds can be opened. Although this method ensures the tightness of the connection between the two molds, it also invisibly increases the workload, which reduces the overall production efficiency.

[0004] Therefore, it is necessary to invent a coupling processing mold that is easy to disassemble to solve the above problems. Summary of the Invention

After the liquid metal solidifies, the upper and lower molds are disassembled and the molded coupling is taken out. However, when connecting the two molds together, in order to ensure the tightness of the connection between the two molds, multiple sets of screws and nuts are usually used to fix the two molds together. This results in the need to turn the screws during the installation and disassembly process of the two molds before the two molds can be opened. Although this approach ensures the tightness of the connection between the two molds, it also invisibly increases the workload, which reduces the overall production efficiency.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a mold for machining a coupling that is easy to disassemble, comprising a top plate, wherein the four corners of the top plate are fixedly connected to columns, and the four corners of the top plate are fixedly connected to the bottom plate via four columns, an open fitting groove is formed inside the bottom plate, and the bottom of the lower mold is fitted in the fitting groove, and the top of the lower mold is covered with an upper mold, and limit rods are provided on both sides of the upper mold, and further comprising: The driving assembly includes a motor fixedly connected to the top wall of the top plate, and an output shaft of the motor passes through the top plate.

The movable component has a gap 1 reserved inside the card block, and the inner wall of the gap 1 is rotatably connected to one end of the inclined rod through a rotating shaft. The movable block has a gap 2 reserved inside, and the inner wall of the gap 2 is rotatably connected to the other end of the inclined rod through a rotating shaft.

[0007] Preferably, a limiting rod 2 is provided inside the upper mold and the snap-fit ​​block fixedly connected to the bottom of the upper mold, and the outer wall of the limiting rod 2 is in contact with the inner wall of the through hole 2 reserved inside the upper mold and the inner wall of the through hole 1 reserved inside the snap-fit ​​block and is slidably connected up and down, and the through hole 1 is connected to the through hole 2, ensuring that the upper mold will not shift during the up and down movement, thereby ensuring the accuracy of matching the upper and lower molds.

[0008] Preferably, there are two limit rods 1, and the two limit rods 1 are symmetrically arranged with reference to the central axis of the top plate as the symmetry axis, and the outer surfaces of the two limit rods 1 are relatively smooth; The two limiting rods pass through the two sides of the upper mold, and the upper mold and the two limiting rods are connected in an upward and downward sliding manner. The limiting rods and the upper mold slidably connected thereto serve to limit the movement direction.

[0009] Preferably, the top end of the second limiting rod is fixedly connected to the plate body of the top plate, and the bottom end of the second limiting rod is fixedly connected to the midpoint position on the midline of the bottom wall of the buckling groove.

[0010] Preferably, the top and bottom of the card block are both provided with inclined surfaces, and the entire card block is in a transverse trapezoidal structure, and the surfaces of the inclined surfaces at both ends of the card block are relatively smooth.

[0011] Preferably, the polished rods are provided in two groups of four in total, and two polished rods are symmetrically fixedly connected inside one buckling groove, and the bottom ends of the polished rods are fixedly connected to the bottom wall of the buckling groove, and the top ends of the polished rods are flush with the notch of the buckling groove.

[0014] In the above technical solution, the technical effects and advantages provided by the present invention are: The present invention starts the motor to adjust the rotation of the threaded rod, and the extension block threadedly connected to the threaded rod adjusts the upper mold fixedly connected to the extension block to move up and down. This facilitates the disassembly of the upper and lower molds and the removal of the formed coupling from the upper and lower molds. The threaded connection has a self-locking function, which ensures the tightness of the upper and lower molds and the convenience of subsequent disassembly of the upper and lower molds. Under the action of the spring force, the two movable blocks fixedly connected to the spring and slidably connected on the same polished rod are subjected to mutual force, causing the oblique rod to push the clamping block toward the direction of the clamping slot reserved in the buckle block, thereby making the clamping block fit tightly with the clamping slot. In this way, the upper and lower molds are fixed for the second time, ensuring the stability of the closed state of the upper and lower molds. At the same time, the upper mold descends, driving the snapping block fixedly connected to it to descend and match the snapping groove. During the descending process of the snapping block, its lower end presses against the inclined surface reserved on the top of the card block. The card block is limited by the protrusion and the slide groove so that it can only move horizontally. At this time, the card block is moved toward the direction of the light rod by the force of the snapping block. Under the action of the rotating inclined rod, the two movable blocks slidingly connected to the light rod are separated and moved. At this time, the movement of the card block is convenient to match the card slot reserved in the snapping block. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The top end of the limiting rod 2 9 is fixedly connected to the plate body of the top plate 1 , and the bottom end of the limiting rod 2 9 is fixedly connected to the midpoint position on the midline of the bottom wall of the buckling groove 102 .

[0023] The top and bottom of the block 106 are both provided with inclined surfaces 1061 , and the entire block 106 is in a transverse trapezoidal structure. The inclined surfaces 1061 at both ends of the block 106 are relatively smooth.

[0027] Working principle: When using a coupling processing mold that is easy to disassemble, first when the upper mold 4 and the lower mold 5 connected together need to be disassembled, the motor 81 is started, and then the rotation of the threaded rod 82 connected to the output shaft of the motor 81 is adjusted, and the extension block 83 fixedly connected to the side of the upper mold 4 is threadedly connected to the threaded rod 82. At the same time, two symmetrically arranged limit rods 1 pass through the two sides of the upper mold 4 and are connected to the upper mold 4 for sliding up and down. As the threaded rod 82 rotates in different directions with the motor 81, the entire upper mold 4 can be adjusted to rise and fall. At this time, the disassembly and separation of the upper mold 4 and the lower mold 5 is convenient, and the formed coupling is conveniently removed from the upper and lower molds. At the same time, during the upward movement of the upper mold 4, the two symmetrical snap-fitting blocks 101 fixedly connected to the upper mold 4 move upward synchronously to leave the inside of the snap-fitting groove 102. When the snap-fitting block 101 moves upward, the snap-fitting block 101 The inclined surface of the internal reserved card slot 107 is against the inclined surface 1061 at the bottom of the card block 106. The card block 106 is limited by the protrusion 1104 and the slide groove 1105 so that it can only move horizontally.

The two inclined inclined rods 109 connected to the card block 106 by the rotating shaft 1103 push the two blocks through the spring 1011 movable sleeve The movable block 108 connected to the outer ring of the polished rod 1010 performs a phase separation movement, so that the clamping block 106 does not hinder the movement of the snapping block 101 (when the snapping block 101 moves downward, the lower end of the snapping block 101 abuts the inclined surface 1061 reserved at the upper end of the clamping block 106. The clamping block 106 moves in the direction of the polished rod 1010 adjacent to it in the same manner as described above, ensuring that the clamping block 106 can match the clamping slot 107 reserved inside the snapping block 101); After the upper mold 4 and the lower mold 5 are fully matched, the two movable blocks 108 fixedly connected to the spring 1011 and slidably connected on the same polished rod 1010 are subjected to mutual force under the action of the force of the spring 1011, so that the oblique rod 109 pushes the clamping block 106 to tightly engage with the clamping groove 107 reserved in the buckling block 101, and the upper mold 4 and the lower mold 5 are fixed for the second time to ensure the stability of the closed state of the upper and lower molds; At the same time, the extension rod 2 9 passes through the through hole 104 and the through hole 2 105 reserved inside the upper mold 4 and the snap-fit ​​block 101, thereby ensuring that no displacement will occur during the up and down movement of the snap-fit ​​block 101 driven by the upper mold 4, ensuring that the upper mold 4 and the lower mold 5 will not be displaced when installed, and that the snap-fit ​​block 101 will not be displaced when matching with the snap-fit ​​groove 102.
