Description
Technical Field
[0001] This utility model relates to the field of rubber and plastic sheet production technology, specifically to an automatic cooling mold for rubber and plastic sheet production. Background Technology
[0002] After being cooled by open milling, the rubber sheet reaches a temperature of approximately 90°C. At this temperature, the rubber sheet is not easily stored and needs to be cooled to room temperature naturally. Multiple cooling rods are installed at the end of the open mill to spread the rubber compound evenly, achieving rapid cooling and ensuring continuous production.
[0003] However, in actual use, the aforementioned equipment has several drawbacks. Firstly, most cooling equipment uses a fixed single-layer or multi-layer drying rod structure, with the drying rods fixedly connected to the support frame. When operators need to pick up or put down the rubber material, they must bend over and reach into the frame, which is not only inconvenient and inefficient but also poses a risk of burns from the high-temperature rubber material. Secondly, the few cooling equipment with pull-out functions mostly have a single-sided, single-group design, meaning that only one group of drying rods can be pulled out in one direction, while the remaining drying rods remain fixed and dense. Even if there is sufficient space in the production area, it is impossible to pull out multiple groups of drying rods simultaneously to achieve a dispersed arrangement. In view of this, we propose an automatic cooling mold for the production of rubber and plastic sheets. Utility Model Content
[0004] The purpose of this invention is to provide an automatic cooling mold for the production of rubber and plastic sheets, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic cooling mold for producing rubber and plastic sheets, comprising a support leg, a support plate fixedly connected to the inner wall of the support leg via a telescopic assembly, a second side plate fixedly connected to the left surface of the support plate near the front, a first side plate fixedly connected to the right surface of the support plate near the rear, and a pull-out cooling assembly provided on the inner wall of the support plate. The pull-out cooling assembly includes two sets of side sliders, which are slidably connected to the inner walls of side plate one and side plate two, respectively. A middle slider is slidably connected to the inner walls of both sides of the support plate. A drying rod is fixedly connected to the opposite side of the middle slider and the side slider. A pivot is rotatably connected to the front surface of the middle set of drying rods. A pull plate is fixedly connected to the outer wall of the pivot. A stop block is fixedly connected to the front surface of the drying rods near both sides. The outer wall of the stop block is inserted into the right inner wall of side plate two.
[0006] Preferably, both side plate one and side plate two are L-shaped, and side plate one and side plate two are arranged in opposite directions. Side plate one, support plate and side plate two together form an S-shape.
[0007] Preferably, the slotted cross-section of the inner right side wall of the pull plate is T-shaped, and the inner right side wall of the pull plate is adapted to the stop block.
[0008] Preferably, the telescopic assembly includes an adjusting screw, the outer wall of which is threadedly connected to the inner wall of the support leg, and a sliding plate is slidably connected to the inner wall of the support leg.
[0009] Preferably, the surface of the sliding plate is provided with a threaded slot, and the outer wall of the adjusting screw is threadedly connected to the inner wall of the threaded slot.
[0010] Preferably, the support plate is provided with fixing components on both the front and rear sides. The fixing components include fixing plates. A set of fixing plates near the side plate is fixedly connected to the front surface of the support plate near the right side. The inner wall of the fixing plate is slidably connected with a plug rod.
[0011] Preferably, a handle is fixedly connected to the side of the insertion rod away from the pull plate, the handle is elastically connected to the fixing plate by a return spring, a receiving plate is fixedly connected to the front surface of the rotating shaft, and the outer wall of the insertion rod is inserted into the inner wall of the receiving plate.
[0012] Compared with the prior art, this utility model provides an automatic cooling mold for the production of rubber and plastic sheets, which has the following beneficial effects: 1. This automatic cooling mold for rubber and plastic sheet production, through the pull-out cooling component, with the cooperation of the side slider and the middle slider, allows operators to remove or place rubber materials without leaning out. They can simply pull the pull plate to move the drying rod out of the frame, greatly improving the convenience and efficiency of operation, while avoiding the risk of burns. At the same time, the S-shaped layout not only provides stable double-sided support for the pull-out cooling component, preventing wobbling when the slider slides, but also reduces the overall footprint of the equipment, improves the utilization rate of the site, and allows the drying rods to be distributed after being pulled out, thereby avoiding the accumulation that would reduce the efficiency of heat dissipation.
[0013] 2. This automatic cooling mold for rubber and plastic sheet production, through telescopic and fixed components, allows the operator to drive the sliding plate to rise and fall along the inner wall of the support leg by rotating the adjusting screw, realizing flexible adjustment of the support plate height. It can be adapted to the discharge port of open mills of different heights, solving the problem of fixed height and poor adaptability of existing equipment. At the same time, it can be inserted into the receiving plate in the storage state to achieve stable fixation of the drying rack position. Attached Figure Description

[0016] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic cooling mold for producing rubber and plastic sheets, including a support leg 1 for supporting the overall device. The inner wall of the support leg 1 is fixedly connected to a support plate 3 for supporting other structures and having slots on both sides through a telescopic component 2 for driving the support plate 3 to rise and fall. A side plate 2 5 for supporting a set of side sliders 61 on the left side near the front is fixedly connected to the left surface of the support plate 3. A side plate 4 for supporting a set of side sliders 61 on the right side near the rear is fixedly connected to the right side. The inner wall of the support plate 3 is provided with a pull-out cooling component 6 for allowing the drying rod 62 to be pulled away from the heat concentration area and for easy access. The pull-out cooling assembly 6 includes side sliders 61 for supporting the drying rods 62 near the outer side. The side sliders 61 are configured in two sets, and the two sets of side sliders 61 are slidably connected to the inner walls of the first side plate 4 and the second side plate 5, respectively. The inner walls of the left and right sides of the support plate 3 are slidably connected to the middle sliders 64 for supporting the drying rods 62 in the center. The opposite side of the middle sliders 64 and the side sliders 61 are fixedly connected to the drying rods 62 for placing the rubber sheets to be cooled. The front surface of the middle set of drying rods 62 is rotatably connected to a pivot 63 for supporting the rotation of the pull plate 65. The outer wall of the pivot 63 is fixedly connected to a pull plate 65 for the operator to pull out the drying rods 62. The front surface of the drying rods 62 near the sides is fixedly connected to a stop block 66 for simultaneously pulling the side drying rods 62 when the middle drying rod 62 is pulled. The outer wall of the stop block 66 is inserted into the right inner wall of the second side plate 5.
[0017] In one embodiment of this utility model, both side plate 4 and side plate 5 are L-shaped and arranged in opposite directions. Side plate 4, support plate 3, and side plate 5 together form an S-shape, so that the drying rods 62 are pulled out and are far apart from each other, preventing heat from accumulating in the middle and reducing heat dissipation efficiency. The slotted cross-section of the inner right side of the pull plate 65 is T-shaped. The inner right side of the pull plate 65 is adapted to the stop block 66, so that the operator can freely choose whether to pull the side drying rods 62 when pulling. In use, the device can be arranged so that the drying rods 62 on both sides are in the center, while the drying rods 62 in the middle are far apart from each other, thus blocking heat accumulation to the greatest extent. The telescopic component 2 includes an adjusting screw 21 for adjusting the extension length of the sliding plate 22. The outer wall of the adjusting screw 21 is threadedly connected to the inner wall of the support leg 1. The inner wall of the support leg 1 is slidably connected to the sliding plate 22 for supporting the up and down movement of the support plate 3.
[0018] In this embodiment of the present invention, the surface of the sliding plate 22 is provided with a threaded slot 23 for inserting into the threaded slot 23 to fix the sliding plate 22. The outer wall of the adjusting screw 21 is threadedly connected to the inner wall of the threaded slot 23. The front and rear sides of the support plate 3 are provided with fixing components 7 for fixing the pull plate 65. The fixing components 7 include fixing plates 71 for supporting the sliding of the insert rod 72. A set of fixing plates 71 near the side plate 4 is fixedly connected to the front surface of the support plate 3 near the right side. The inner wall of the fixing plate 71 is slidably connected with an insert rod 72 for inserting into the receiving plate 75 to fix the pull plate 65. The side of the insert rod 72 away from the pull plate 65 is fixedly connected with a handle 73 for the operator to pull the insert rod 72. The handle 73 and the fixing plate 71 are elastically connected by a return spring 74 for continuously pulling the handle 73. The front surface of the rotating shaft 63 is fixedly connected with a receiving plate 75 for receiving the insert rod 72. The outer wall of the insert rod 72 is inserted into the inner wall of the receiving plate 75.
[0019] In this utility model, during use, rotating the adjusting screw 21 in the telescopic assembly 2 causes the outer wall of the adjusting screw 21 to be threadedly connected to the inner wall of the support leg 1 and the threaded slot 23 of the sliding plate 22. During rotation, the sliding plate 22 can be driven to rise and fall stably along the inner wall of the support leg 1, thereby driving the support plate 3 and the S-shaped frame above to adjust their height synchronously until the support surface formed by the drying rod 62 is flush with the discharge port of the open mill, ensuring that the high-temperature sheet can be dropped smoothly and completing the initial positioning. The 90°C high-temperature rubber and plastic sheet discharged from the open mill is placed and laid flat on the drying rod 62 along the opening direction of the S-shaped frame formed by the side plate 1 4, the side plate 2 5 and the support plate 3: L Side plate 4 and side plate 5 are arranged in opposite directions. At this time, the outer wall of the stop block 66 is inserted into the inner wall of the right side of side plate 5, realizing the initial storage and positioning of the pull-out cooling component 6 and preventing the drying rod 62 from accidentally sliding when the board is placed. The selectable pull-out and dispersed heat dissipation are achieved by rotating the pull plate 65 to select the pull-out and disperse the heat dissipation of the drying rod 62 according to the size of the board and the space of the site. The core relies on the rotation of the rotating shaft 63, the matching of the pull plate 65, and the linkage of the slider structure. When the pull plate 65 is rotated, since the pull plate 65 is fixedly connected to the rotating shaft 63 and the rotating shaft 63 is rotatably connected to the middle drying rod 62, the pull plate 65 can be freely adjusted around the drying rod 62, so that the T-shaped slot on the inner wall of its right side can selectively match the stop block 66. If it is necessary to enhance local heat dissipation, rotate the pull plate 65 so that the slot is only aligned and engaged with the stop block 66 of the middle drying rod 62. Pulling the pull plate 65 outward will only drive the middle slider 64 along the support plate. 3. The inner wall slides, corresponding to the independent extension of a single middle drying rod 62; if overall dispersed cooling is required, rotate the pull plate 65 so that the slot is simultaneously aligned and engaged with the stop blocks 66 of the middle and side drying rods 62. When the pull plate 65 is pulled, the side slider 61 is simultaneously driven to slide along the inner wall of side plate 1 4 and side plate 2 5, so that multiple drying rods 62 can extend simultaneously. Since the frame is S-shaped, the drying rods 62 naturally move away from each other after being pulled out, expanding the heat dissipation gap between the boards and avoiding heat accumulation in the middle. During the pulling state locking and cooling process, after the drying rod 62 is pulled to the target position, it is stably locked by the fixing component 7. The receiving plate 75, which rotates synchronously with the rotating shaft 63, has been adjusted to the position aligned with the insertion rod 72 according to the angle of the pull plate 65. When the handle 73 is released, the return spring 74 releases the elastic potential energy and pushes the insertion rod 72 to slide along the inner wall of the fixing plate 71 until the outer wall of the insertion rod 72 is inserted into the inner wall of the receiving plate 75. At this point, the drying rod 62 is locked in place and does not wobble under the double support of the S-shaped frame. Air can flow smoothly along the gaps between the drying rods to accelerate the cooling of the sheet. After the rubber and plastic sheet cools to room temperature, pull the handle 73 to disengage the insert rod 72 from the receiving plate 75 and push the pull plate 65 in the opposite direction. Through the stop block 66, the side slider 61 and the middle slider 64 are reset synchronously. The drying rod 62 is retracted into the S-shaped frame, and the stop block 66 is re-inserted into the inner wall of the side plate 2 5 to complete the storage and positioning.Operators do not need to lean out; they can directly pick up and put down the cooled sheet material from above or to the side of the frame. After the material is picked up, the equipment returns to its initial state and waits for the next round of work. The entire process is achieved by rotating the pull plate 65 to switch the pull mode. The S-shaped layout enhances the dispersion of heat dissipation, and the fixed component 7 ensures stable operation, which is fully adapted to the cooling requirements of rubber and plastic sheets.
[0020] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
