Description

Technical Field

[0001] The utility model relates to the technical field of injection mold maintenance, in particular to an injection mold maintenance operation platform. Background Art

[0002] During the use of injection molds, problems such as mold channel blockage or difficulty in gate removal are inevitable. At this time, the injection molding company needs to remove the injection mold from the injection molding equipment and have it repaired by a technician. In order to ensure the strength of the injection mold, the injection mold is usually made of large metal blocks, which makes its overall weight larger. During the maintenance process, the staff needs to frequently turn over the injection mold, which is time-consuming and labor-intensive, resulting in low maintenance efficiency of the injection mold.

[0003] The utility model with publication number CN213947155U proposes an injection mold maintenance operating table, including a frame, a left clamping mechanism and a right clamping mechanism, wherein the left clamping mechanism includes a left base, a left rotating shaft, a rotating handle and a left clamping assembly, and the right clamping mechanism includes a right base, a right rotating shaft and a right clamping assembly. The left clamping mechanism and the right clamping mechanism respectively clamp the two ends of the injection mold. The staff rotates the injection mold by turning the handle according to the maintenance needs, and uses the ejector pin to lock the left rotating shaft, thereby achieving a smooth and efficient locking of the injection mold at a set angle, eliminating the staff from frequently and laboriously turning the injection mold, thereby effectively improving the maintenance efficiency of the injection mold.

[0004] However, the above-mentioned prior art still has some shortcomings when in use: 1. When the mold and the operating table are docked, a crane is needed to assist the mold to dock with the left clamping mechanism and the right clamping mechanism. The crane is also needed when disassembling after maintenance. That is to say, in the process of replacing the mold that needs to be repaired, it is necessary to operate the crane and different molds to switch the connection, and then align the connection. Switching the connection and aligning the connection will take up a lot of time, which will affect the efficiency of mold maintenance; 2. The position of the mold cannot be adjusted after it is docked with the left clamping mechanism and the right clamping mechanism. For example, for some molds with a smaller thickness, the height of one side of the mold will increase. At this time, the operator needs to climb up for maintenance. After turning over, the height of the other side of the mold will decrease. At this time, the maintainer will squat or bend over for maintenance, which leads to the defect of high labor intensity for the operator.

[0005] To this end, the utility model provides an injection mold maintenance operation platform. Utility Model Content

The top of the arc-shaped support plate and the bottom of the vertical shaft are rollingly matched. When the vertical shaft is located between the left vertical plate and the right vertical plate, the vertical shaft is located above the arc-shaped support plate.

[0008] Furthermore, the away-from sides of the left vertical plate and the right vertical plate are fixedly connected to control motors, and the other ends of the left transmission shaft and the right transmission shaft are respectively fixedly connected to the output shafts of adjacent control motors.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3The utility model provides a technical solution: an injection mold maintenance operation platform, including a support platform 1, a left vertical plate 2 and a right vertical plate 3 are arranged on the top of the support platform 1, and the space between the left vertical plate 2 and the right vertical plate 3 is a mold installation space, that is, a maintenance station. The opposite sides of the left vertical plate 2 and the right vertical plate 3 are rotatably connected with a coaxial left transmission shaft 21 and a right transmission shaft 31, respectively, and the opposite ends of the left transmission shaft 21 and the right transmission shaft 31 are fixedly connected with a left groove clamping plate 211 and a right groove clamping plate 311 with opposite opening ends, respectively, and the function of the left groove clamping plate 211 and the right groove clamping plate 311 is to clamp the mold.

[0023] In the present technical solution, the bottom of the right vertical plate 3 is fixedly connected to the top of the support platform 1, that is, the space between the right vertical plate 3 and the left vertical plate 2 is fixed, and the middle part of the bottom of the left vertical plate 2 is fixedly connected with a column 4, and the bottom of the column 4 is fixedly connected to the top of the support platform 1. A rotating sleeve 5 is sleeved on the column 4, and the outer peripheral wall of the rotating sleeve 5 is fixedly connected with at least two joists 6 evenly distributed in the circumferential direction. In this embodiment, the joists 6 are arranged horizontally, and when the rotating sleeve 5 rotates, the joists 6 will move with the rotating sleeve 5. A vertical shaft 7 near one end is slidably connected to the joists 6 up and down, and specifically, a guide sleeve near one end can be fixedly connected to the joists 6, and the guide sleeve is sleeved on the outside of the vertical shaft 7. A groove tray 8 is fixedly connected to the top of the vertical shaft 7, so that when the rotating sleeve 5 rotates, the groove tray 8 on each joist 6 will pass through the position between the left groove clamping plate 211 and the right groove clamping plate 311, wherein the groove tray 8 is used to place the mold to be repaired, and it should be noted that the width of the groove tray 8 is less than the length of the mold. Among them, a rubber pad 81 is bonded to the bottom of the inner groove tray 8, and evenly distributed protrusions 811 are fixedly provided on the upper end surface of the rubber pad 81. The rubber pad 81 cooperates with the vertical plates on both sides of the groove tray 8 to stably support the mold.

[0024] The bottom of the support platform 1 is fixedly connected with a lifting cylinder 9, the top gap of the output shaft of the lifting cylinder 9 passes through the support platform 1 and is fixedly connected with an arc-shaped support plate 91 located between the left vertical plate 2 and the right vertical plate 3, the top of the arc-shaped support plate 91 and the bottom of the vertical shaft 7 are rollingly matched, and a roller can be installed at the bottom of the vertical shaft 7. When the vertical shaft 7 is located between the left vertical plate 2 and the right vertical plate 3, the vertical shaft 7 is located above the arc-shaped support plate 91, that is, when the lifting cylinder 9 drives the arc-shaped support plate 91 to descend, the vertical shaft 7 will descend, and when the arc-shaped support plate 91 rises, it will drive the vertical shaft 7 to rise. When the arc-shaped support plate 91 descends, the upper mold of the groove tray 8 will be lifted by the lower side wall of the left groove clamping plate 211 and the right groove clamping plate 311, so as to realize the rapid non-fastening connection between the mold and the left groove clamping plate 211 and the right groove clamping plate 311, and at this time, the groove tray 8 can be controlled to descend away from the mold.

[0025] Furthermore, the away sides of the left vertical plate 2 and the right vertical plate 3 are fixedly connected with the control motor 101, and the other ends of the left transmission shaft 21 and the right transmission shaft 31 are respectively fixedly connected to the output shafts of the adjacent control motors 101. The control motors 101 connected to the left vertical plate 2 and the right vertical plate 3 are operated in a synchronous manner, thereby controlling the synchronous movement of the left slot-shaped clamping plate 211 and the right slot-shaped clamping plate 311, and then driving the clamped mold to rotate.

[0026] In this embodiment, both sides of the left groove clamping plate 211 and the right groove clamping plate 311 are fixedly connected with the cylinder 102, and the left groove clamping plate 211 and the right groove clamping plate 311 are provided with a pressing plate 103 near both sides and fixedly connected with the back side and the adjacent cylinder 102 output shaft. When the cylinder 102 pushes, the pressing plate 103 will clamp the mold to realize the control of the clamping and release of the mold, which is convenient for the subsequent control of the mold flipping. It should be noted that the position of the pressing plate 103 is controlled by the cylinder 102, which is convenient for adjusting the position of the mold.

[0027] Furthermore, a resistance-increasing rubber pad 1031 is fixedly connected to the side of the pressing plate 103 facing away from the cylinder 102. The resistance-increasing rubber pad 1031 plays a role in clamping and preventing slipping, and has a higher reliability in clamping and relaxing the mold.

[0028] In this embodiment, a driving motor 104 is fixedly connected to the top of the supporting platform 1, and the output shaft of the driving motor 104 is fixedly connected to a driving gear 1041. The outer fixed sleeve of the rotating sleeve 5 is provided with a passive gear 51 meshing with the driving gear 1041. The driving motor 104 drives the rotating sleeve 5 to rotate through the meshing of the passive gear 51 and the driving gear 1041, and has the function of motorized control of the rotation of the rotating sleeve 5.

[0029] In this embodiment, the inner arc wall of the arc-shaped support plate 91 is opposite to the column 4, the upper end surface of the arc-shaped support plate 91 is an arc-shaped surface and the height of the middle part is higher than the height of the two ends, that is, the upper end surface of the arc-shaped support plate 91 is an upper and lower slope structure. After the roller at the bottom of the vertical shaft 7 contacts one end of the upper end surface of the arc-shaped support plate 91, as the vertical shaft 7 continues to move, the vertical shaft 7 will be lifted. This arrangement enables the two ends of the mold to move directly into the groove cavity of the left groove clamping plate 211 and the right groove clamping plate 311, without controlling the action of the lifting cylinder 9 to assist the arc-shaped support plate 91 and the vertical shaft 7 to dock.

[0030] Working principle: 1. Loading of mold: hang the mold directly on a groove tray 8, then start the driving motor 104, the driving gear 1041 drives the passive gear 51 to rotate, the rotating sleeve 5 rotates, and a groove tray 8 carrying the mold makes an arc motion. When the vertical shaft 7 at the bottom of the groove tray 8 contacts one end of the upper end surface of the arc-shaped support plate 91, the vertical shaft 7 is pushed upward. With the continuous rotation of the rotating sleeve 5, the groove tray 8 moves to between the left groove clamping plate 211 and the right groove clamping plate 311, the height of the groove tray 8 increases, and the two ends of the mold are located in the groove between the left groove clamping plate 211 and the right groove clamping plate 311. At this time, the non-clamping operation of loading the mold is completed.

[0031] 2. Clamping and height adjustment of the mold: When the two ends of the mold are located in the groove between the left groove-shaped clamping plate 211 and the right groove-shaped clamping plate 311, the lifting cylinder 9 is controlled to move according to the height of the mold, so that the mold rises to a state where its horizontal center line is approximately coaxial with the center line of the left transmission shaft 21. At this time, the cylinders 102 at the top of the left groove-shaped clamping plate 211 and the right groove-shaped clamping plate 311 are controlled to move synchronously, and the pressure plate 103 moves downward and squeezes the mold. Then, the cylinders 102 at the bottom of the left groove-shaped clamping plate 211 and the right groove-shaped clamping plate 311 are controlled to move synchronously, and the corresponding pressure plate 103 moves upward and squeezes the bottom of the mold, thereby completing the clamping and fixing operation of the mold. At this time, when the left transmission shaft 21 and the right transmission shaft 31 are controlled to rotate synchronously in different directions, the mold will flip over, and the height of each surface is approximately equal when flipping, which is convenient for maintenance operations.

[0032] 3. Unloading of molds: When the current mold is being repaired, other molds can be hung on the grooved tray 8 on another supporting beam 6. After the current mold is repaired, the left grooved clamp 211 and the right grooved clamp 311 are controlled to be in a vertical state, and then the lifting cylinder 9 is controlled to push the grooved tray 8 close to the mold, and then the cylinder 102 is controlled to return. At this time, the repaired mold will be lifted by the grooved tray 8, and then the rotating sleeve 5 is controlled to rotate to realize the unloading of the mold.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
