Description
Technical Field
[0001] This utility model relates to the field of high-performance composite material extrusion molding technology, and specifically discloses a carbon fiber mold cold and hot semi-automatic molding line. Background Technology
[0002] In the processing of high-performance composite material products, cold and hot forming equipment are needed to realize the two steps of carbon fiber forming, namely hot forming and cold forming. Therefore, the two steps need to be carried out in sequence. The current technology realizes the forming independently. The mold is transferred to the two presses by personnel or equipment, and the product is extruded and formed by cold and hot presses respectively.
[0003] The technical drawbacks of the molding methods described above can be summarized as follows: 1. Low efficiency. In the current trend of automation equipment transformation, the current production needs can no longer be met by a single machine operating manually. 2. If automated operation is adopted, precise positioning design for mold entry and exit is required. Since these molds are mostly large molds, when forming a production system or production line, the uncertainty factors during worker operation increase, leading to an increase in the failure rate of molds and equipment, a decrease in product yield, and even an increase in the risk of workplace accidents.
[0004] In view of the above-mentioned drawbacks, as a technical unit in the heavy press equipment industry, it is very necessary to design a semi-automatic hot and cold forming line for carbon fiber molds. The purpose is to replace the existing manual movement between two machines with automatic mold changing, minimize manual operation, improve production efficiency and yield, and reduce the probability of work-related accidents. Utility Model Content

Detailed Implementation
[0014] As shown in the attached drawings, this utility model discloses a semi-automatic hot and cold forming line for carbon fiber molds. This embodiment provides a detailed demonstration of the specific structure of the semi-automatic hot and cold forming line for carbon fiber molds, and explains the usage method through specific embodiments. Those skilled in the art can implement this technical solution or make further technical extensions based on this technical solution. The scope of protection of this utility model is subject to the claims.
[0015] Example 1: A semi-automatic hot and cold forming line for carbon fiber molds, the specific structure of which and the function of each part are described below: It includes a loading platform 4 and a unloading platform 40. A transverse track 5 and a transverse rack 51 are provided between the loading platform 4 and the unloading platform 40. A transverse trolley 3 is provided on the transverse track 5. A cold press 1 and a hot press 2 are provided within the movement range of the transverse trolley 3.
[0016] More specifically, the loading platform 4 is positioned at intervals to the cold press 1, and the unloading platform 40 is positioned at intervals to the hot press 2. The traverse trolley 3 and the traverse track 5 are positioned within the gaps between these intervals. This can be understood as the loading platform 4, unloading platform 40, cold press 1, and hot press 2 forming a quadrilateral structure. The traverse trolley 3 is equipped with a traverse drive motor 33, and traverse movement is achieved through the engagement of the drive gear on the traverse drive motor 33 with the traverse rack 51.
[0017] Both the loading platform 4 and the unloading platform 40 are equipped with top pulleys 42 and side guide pillars 43. A flow guide frame 41 is provided at the outermost edge of both platforms to facilitate the inward movement of the mold. Vertical push cylinders 44 are also provided on the top surfaces of both platforms, with a platform pin 46 at the top. Locking guide blocks 46 on both platforms provide guidance for the vertical movement of the platform pin 46, thus blocking and limiting the mold. Furthermore, since the platform pin 46 is automatically controlled by the vertical push cylinder 44, a plug-in pin 17 is provided on the guide block 46 for double safety. This allows for manual secondary limiting by the operator, ensuring the mold does not accidentally slip.
[0018] The traverse trolley 3 has a pulley 35 on its top. A longitudinal traverse assembly 7 is also installed inside the traverse trolley 3. The longitudinal traverse assembly 7 includes a longitudinal traverse track 71, on which a longitudinal traverse plate 74 is mounted. The longitudinal traverse plate 74 is connected to a longitudinal traverse drive unit, which is a longitudinal traverse drive motor 70. This motor drives a drive gear 72 to rotate, which in turn drives a drive chain 73 to move in a circular motion, thereby moving the entire longitudinal traverse plate 74 longitudinally. Two hooks 76 are hinged to the longitudinal traverse plate 74 via a hinge seat 75. The hooks 76 are connected together by a linkage rod 79. Each hook 76 has a locking part 77 at its front end. In this embodiment, the locking part is an clearance notch. Those skilled in the art can make equivalent structural replacements based on understanding the design intent. This utility model also includes a clamping drive unit 78 in conjunction with the hooks 76. The clamping drive unit 78 is connected to a vertical drive cylinder or electric actuator. With the above structural configuration, the longitudinal movement assembly 7 can move longitudinally on top of the transverse movement trolley 3, and drive the two hooks 76 to hook the mold and drive the longitudinal movement during the longitudinal movement. In this embodiment, a mold support plate 9 is provided to support the mold, and grooves 91 are provided on the mold support plate 9 to realize the hooking of the locking part 77.
[0019] The traverse trolley 3 is also equipped with a trolley end sensor 34 and a roof positioning pin. The roof positioning pins are the trolley end positioning pin 31 and the trolley front positioning pin 32. The vertical drive structure of the trolley end positioning pin 31 and the trolley front positioning pin 32 is the same as the drive principle of the platform pin 46, and will not be described in detail here. This utility model uses the trolley end positioning pin 31, the trolley front positioning pin 32, and the trolley end sensor 34 to constrain and detect the position of the mold.
[0020] This utility model also provides press guide wheels 64 on the worktables of both the cold press 1 and the hot press 2, and provides end mold positioning pins and end sensors on the cold press 1 and the hot press 2, respectively. More specifically, the cold press worktable 10 is provided with a cold press end sensor 14, a cold press end positioning pin 15, and a cold press front positioning pin (not labeled); the hot press worktable 20 is provided with a hot press front positioning pin 21, a hot press end positioning pin 22, and a hot press end sensor 23; the fixing method and position of the cold press front positioning pin (not labeled) can refer to the installation method of the hot press end positioning pin 22. The cold press end sensor 14 and the hot press end sensor 23 are mainly used to detect whether the mold is in place and whether the longitudinal movement assembly 7 needs to pull the mold out or send it in.
[0021] Both the cold press 1 and the hot press 2 described in this utility model adopt a downward pressing design, that is, the mold support plate 9 is placed still on the worktable, and the upper part presses down to form the material. In this process, it is necessary to ensure that the mold support plate 9 moves smoothly on the worktable 10 of the cold press or the worktable 20 of the hot press, and also to ensure that the press guide rollers 64 on the worktable 10 of the cold press or the worktable 20 of the hot press are not damaged. This utility model designs the press guide rollers 64 as a vertical lifting structure, specifically as follows: Figure 3 , 4 As shown, press guide wheel fixing holes 11 are provided on the cold press worktable 10 or the hot press worktable 20. The press guide wheel 64 is set in the press guide wheel fixing hole 11, and a guide wheel drive cylinder 6 is set in the corresponding press guide wheel fixing hole 11. The guide wheel drive cylinder 6 is fixed on the drive cylinder base 61. The guide wheel drive cylinder 6 drives the drive block 62 to move vertically. A drive rod 63 is set on the top of the drive block 62, and the press guide wheel 64 is set on the drive rod 63. When the mold support plate 9 moves in and out of the cold press 1 and the hot press 2, the press guide wheel 64 rises to achieve guide wheel support. When extrusion molding, the press guide wheel 64 descends, and the mold support plate 9 is placed on the cold press worktable 10 or the hot press worktable 20, changing from point support to surface support, which effectively improves the stability of extrusion molding. In conjunction with the above structural setup, the end positioning pin 15 of the cold press, the front positioning pin (not marked) of the cold press, the front positioning pin 21 of the hot press, and the end positioning pin 22 of the hot press are all fixed designs. When the press guide wheel 64 is raised, the above positioning pins do not function. When the press guide wheel 64 is lowered, the front and rear positioning in the working state is achieved through all the above positioning pins.
[0022] This utility model also provides several guide wheel frames 12 on the cold press worktable 10 or the front end of the hot press worktable 20, and achieves stable connection when the mold enters and exits the cold press worktable 10 or the hot press worktable 20 through the leading press guide wheels 13 on the several guide wheel frames 12.
[0023] Because the transverse trolley 3 needs to circulate between the loading platform 4 and the unloading platform 40 during operation, serving as the connecting platform between the loading platform 4 and the cold press worktable 10, and between the unloading platform 40 and the hot press worktable 20, it is essential to ensure that the transverse trolley 3 does not shift relative to the loading platform 4 and the unloading platform 40 during the longitudinal movement of the mold support plate 9. Therefore, this utility model incorporates the following structural design, such as... Figure 10 As shown, a transverse positioning cylinder 8 is provided on the transverse trolley 3, and a trolley positioning pin 81 is provided on the transverse positioning cylinder 8. Positioning points are respectively set on the loading platform 4 and the unloading platform 40 corresponding to the trolley positioning pin 81. When the transverse trolley 3 moves to the position of the loading platform 4 and the unloading platform 40, the positions of the two are fixed by inserting the trolley positioning pin 81 on the transverse positioning cylinder 8 into the positioning point.
[0024] In summary, this utility model achieves positioning through the positioning devices on the loading platform 4 and unloading platform 40, and the cold press 1 and hot press 2. The transverse trolley 3 enables the mold or mold 9 pallet to move sequentially on the cold press 1 and hot press 2. Simultaneously, it coordinates with external personnel to unload the mold on the loading platform 4 and move it towards the external unloading platform 40. This production line can achieve sequential movement of a single set of molds, and can also achieve continuous operation with two or three sets of molds cyclically entering and exiting. It has a high degree of automation; the entire mold loading and unloading process, as well as mold movement and selection, can be semi-automatic or automatic. Multiple positioning pins achieve precise positioning and provide sensing signals to support the movement of the transverse trolley 3 and the longitudinal assembly 7, enabling synchronous production of multiple sets of molds. This improves production efficiency and product forming accuracy, increases product yield, reduces manual operation, and lowers the probability of workplace accidents.
