Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mold guiding technology, specifically relating to a multi-layer molding material rack guiding device. Background Technology
[0002] PVC structural foam is widely used in wind power, shipbuilding, aerospace and other fields due to its light weight, high strength, high rigidity and good chemical corrosion resistance. It is mainly produced by injecting material into a mold, then adding an upper mold or cover plate to the lower mold, and finally feeding it into a molding press for vulcanization and foaming. In actual production, to improve production efficiency and reduce equipment investment, presses often use multiple layers, such as 10-20 layers of hot plates for simultaneous heating. During this process, to ensure continuity, the upper and lower molds and materials are first fed into the feeding rack or the molds and materials are output onto the discharge rack. In actual use, misalignment of the multi-layer molds and brackets or deformation of the materials can cause the upper mold to become displaced. Especially on the discharge rack, the materials that have undergone high-temperature and high-pressure treatment will have certain stress after the pressure is released, causing the original material rack to collide or the upper mold to become misaligned. In existing technology, guide posts are usually only set at both ends of each layer of the material rack. This kind of guide post design is too simple and the layout is unreasonable. The stroke in the middle of each layer of the material rack is blank and unguided, allowing the mold to move freely. This often results in collisions with the transmission device, the mold running beyond the device and getting stuck, and in severe cases, the guide posts may break, causing the mold to fall and other risks, which seriously affect product quality and pose a high safety risk.

Installing anti-detachment low-roller, high-side guide wheels solves this problem and eliminates safety hazards. This ensures the dies move along a defined path, effectively guaranteeing that the upper and lower dies feed and discharge materials along a predetermined stroke, preventing misalignment and reducing the risk of falling.

Detailed Implementation
[0026] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0027] Example 1, see Figure 1-4 .
[0028] A multi-layer molding material rack guide device includes a material rack beam 1, connecting rods 2, and two sets of parallel and symmetrically arranged material rack columns 3; at least three sets of connecting rods are fixedly connected to one end of each material rack column 3 facing the symmetrical plane, and the other end of each connecting rod 2 is detachably fixedly connected to the horizontally arranged material rack beam 1; low roller high side guide device 4 and rotating guide device 5 are rotatably and alternately arranged on both sides of the material rack beam 1.
[0029] Furthermore, the low roller high side guide device 4 includes a first roller 42 and a low roller high side guide wheel 43; the first roller 42 and the low roller high side guide wheel 43 are coaxially and rotatably disposed on both sides of the material rack beam 1; the low roller high side guide wheel 43 is located on the side away from the plane of symmetry relative to the first roller 42; the high side of the low roller high side guide wheel 43 is located at the end away from the plane of symmetry relative to the low roller side.
[0030] Furthermore, the low roller high side guide device 4 also includes a first rotating shaft 41 and a first limiting nut 44; a first keyhole 45 is provided on the first rotating shaft 41; a first keyway 46 is provided on the side of the first roller 63 near the plane of symmetry, and a first connecting key 47 is provided in the first keyway 46 to cooperate with the first keyhole 45 and the first keyway 46; the first connecting key 47, together with the first keyhole 45, the first keyway 46 and the first limiting nut 44, fixes the first roller 42 to one end of the first rotating shaft 41; a first through hole 11 is provided horizontally through the material frame beam 1; the other end of the first rotating shaft 41 passes through the first through hole 11 and is fixedly connected to the geometric center of the low roller side of the low roller high side guide wheel 43; the first rotating shaft 41 and the material frame beam 1 are rotatably connected through the first through hole 11.
[0031] Furthermore, the rotating guide device 5 includes a second rotating shaft 51, a second roller 52, a third roller 53, and a second limiting nut 54; a second keyhole 55 is provided on the second rotating shaft; a second keyway 56 is provided on the side of the second roller near the plane of symmetry, and a second connecting key 57 is provided in the second keyway 56 to cooperate with the second keyhole 55 and the second keyway; the second connecting key 57, in conjunction with the second keyhole 55, the second keyway 56, and the second limiting nut 54, fixes the second roller 52 to one end of the second rotating shaft 51; a second through hole 12 is horizontally provided through the material rack beam 1; the other end of the second rotating shaft 51 passes through the second through hole and is fixedly connected to the third roller; the second rotating shaft 51 and the material rack beam 1 are rotatably connected through the second through hole 12.
[0032] By alternately rotatably arranging a low-roller high-side guide device 4 and a rotating guide device 5 on both sides of the material rack beam 1, the mold can be effectively guided as it moves on the material rack. The rotating guide device 5 provides auxiliary guidance and is less expensive than the low-roller high-side guide device 4, thus reducing equipment costs while ensuring effective overall guidance. The low-roller sections of the second roller 52, the third roller 53, and the low-roller high-side guide wheel 43 have the same diameter. In use, the heated material mold is distributed in layers on the material rack beam 1. The low-roller high-side guide device 4 and the rotating guide device 5 reduce moving friction and provide guidance. The low-roller high-side guide wheel 43, the first roller 42, the second roller 52, and the third roller 53 maintain a fixed fit with the first and second rotating shafts 41 and rotate relative to the material rack beam 1 through holes. At this time, the low roller high-side guide wheels 43 and the first roller 42 on both sides of the low roller high-side guide device 4 rotate simultaneously. If the heated material mold shifts outward, the high side of the continuously rotating low roller high-side guide wheel 43 can block further movement of the mold, and the tangential force generated during rotation can quickly correct the direction of mold movement. Multiple sets of the guide devices are used in series along the length of the material rack beam.
[0033] Compared with existing technologies, this utility model restricts the movement of the upper and lower dies within the entire material rack device by installing a positioning guide device in the direction of movement of the conveyor rail. Utilizing a low-roller, high-side guide device and a rotating guide device, it ensures that the upper and lower dies smoothly reach the designated positions. Especially during the movement of the unloading device, heated materials are prone to deformation and lifting under stress, potentially causing irregular movement of the upper and lower dies. Installing anti-detachment low-roller, high-side guide wheels solves this problem and eliminates safety hazards. This ensures that the dies move along a defined path, effectively guaranteeing that the upper and lower dies feed and discharge materials along a predetermined stroke, preventing misalignment and reducing the risk of falling.
[0034] Example 2, see Figure 4-7 .
[0035] A multi-layer molding material rack guide device includes a material rack beam 1, connecting rods 2, and two sets of parallel and symmetrically arranged material rack columns 3; at least three sets of connecting rods 2 are fixedly connected to one end of each material rack column 3 facing the symmetrical plane, and the other end of each connecting rod 2 is detachably fixedly connected to the horizontally arranged material rack beam 1; low roller high side guide device 4 and rotating guide device 5 are rotatably and alternately arranged on both sides of the material rack beam 1.
[0036] Furthermore, the low roller high side guide device 4 includes a first roller 42 and a low roller high side guide wheel 43; the first roller 42 and the low roller high side guide wheel 43 are coaxially and rotatably disposed on both sides of the material rack beam 1; the low roller high side guide wheel 43 is located on the side away from the plane of symmetry relative to the first roller 42; the high side of the low roller high side guide wheel 43 is located at the end away from the plane of symmetry relative to the low roller side.
[0037] Preferably, the low-roller high-side guide device 4 further includes a first rotating shaft 41, a first roller 42, a low-roller high-side guide wheel 43, and a first limiting nut 44; the first rotating shaft 41 is horizontally fixedly connected to the left and right sides of the material rack beam 1; the first roller 42 and the low-roller high-side guide wheel 43 are rotatably connected to the two ends of the first rotating shaft 41 away from the material rack beam 1, respectively; the first roller 42 and the low-roller high-side guide wheel 43 are limited by the first limiting nut 44 at the two ends of the first rotating shaft 41 away from the material rack beam 1.
[0038] Preferably, the rotating guide device 5 includes a second rotating shaft 51, a second roller 52, a third roller 53, and a second limiting nut 54; the second rotating shaft 51 is horizontally fixedly connected to the left and right sides of the material rack beam 1; the second roller 52 and the third roller 53 are rotatably connected to the two ends of the second rotating shaft 51 away from the material rack beam 1, respectively; the second roller 52 and the third roller 53 are limited by the second limiting nut 54 at the two ends of the second rotating shaft 51 away from the material rack beam 1.
[0039] The difference between this embodiment and embodiment 1 is that the first rotating shaft 41 and the second rotating shaft 51 are fixed on both sides of the material rack beam 1, and the low roller high side guide wheel 43, the first roller 42, the second roller 52, and the third roller 53 are rotatably connected relative to the first rotating shaft 41 and the second rotating shaft 51.
[0040] In use, the heated material mold is layered on the material rack beam 1 of this device. The low-roller high-side guide device 4 and the rotating guide device 5 reduce moving friction and provide guidance. The low-roller high-side guide wheel 43, the first roller 42, the second roller 52, and the third roller 53 rotate relative to the first rotating shaft 41 and the second rotating shaft 51. At this time, the first roller 42 on one side of the low-roller high-side guide device 4 rotates. If the heated material mold shifts outward to the low-roller side of the low-roller high-side guide wheel 43, the low-roller high-side guide wheel 43 will rotate under the action of friction. After shifting further to the high-side side, the continuously rotating high-side side of the low-roller high-side guide wheel 43 can block further movement of the mold. The tangential force generated during rotation can correct the direction of mold movement.
[0041] Compared with Embodiment 1, the low roller high edge guide device 4 and the rotating guide device 5 provided in this embodiment have less friction. In this way, the outer low roller high edge guide wheel 43 does not rotate when the mold does not have a significant tendency to deviate in direction, which reduces the generation of wear. Compared with Embodiment 1, the maintenance cost can be significantly reduced and maintenance is easier while maintaining the mold guiding function unchanged.
[0042] Example 3, see Figure 8 and Figure 9 This embodiment is an improvement on embodiment 2.
[0043] The low-roller high-side guide wheel 43, the first roller 42, the second roller 52 and the third roller 53 are all designed with roller shafts; the inner rings of the low-roller high-side guide wheel 43 and the first roller 42 are both interference-fitted with the first rotating shaft 41; the inner rings of the second roller 52 and the third roller 53 are both interference-fitted with the second rotating shaft 51.
[0044] This method further reduces wear and makes maintenance more convenient while maintaining the guiding function of the mold. It also enhances the rotational stability of the low-roller high-side guide device and the rotating guide device, thereby better achieving the guiding function.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
