[0023] With reference to Figure 1 - Figure 4 An embodiment provided by the utility model: a high-precision automobile air conditioner panel mold, including mounting bottom plate 1 and upper die 5, the top end of mounting bottom plate 1 is fixedly connected with lower die 6 in the side, the top of lower die 6 is provided with forming cavity, the inside of lower die 6 is provided with mounting cavity 803, movable rod 805 is slidably connected in the through hole of the inner wall of mounting cavity 803, second spring 806 is arranged on the outside of movable rod 805, connecting block 807 is fixedly connected to one end of movable rod 805, moving plate 804 is fixedly connected to the other end of movable rod 805, the inner wall of mounting cavity 803 is fixedly connected with limiting plate 812, ejector rod 810 is slidably connected in the through hole of the inside of limiting plate 812, fixed block 809 is fixedly connected to the outside of ejector rod 810, ejection plate 811 is fixedly connected to the top end of ejector rod 810, upper die 5 is arranged directly above lower die 6, directional rod 801 is fixedly connected to the bottom of one side of upper die 5, pulley 802 is movably installed at the bottom of directional rod 801, and buffer assembly is arranged on the front and rear sides of lower die 6. Fixed block 809 is slidably connected to the inner wall of sliding groove 808, the longitudinal section of connecting block 807 is trapezoidal, one end of second spring 806 is fixedly connected to the outside of moving plate 804, and the other end of second spring 806 is fixedly connected to the inner wall of mounting cavity 803.
[0024] Specifically, the installation base plate 1 provides a stable support base, a lower mold 6 is installed in the top middle side thereof, and the top of the lower mold 6 is provided with a forming cavity for forming an automobile air conditioner panel. An installation cavity 803 is formed in the lower mold 6, and an upper mold 5 is controlled to move up and down by a hydraulic system. The bottom end of the upper mold 5 is fixedly connected to a directional rod 801 on one side in the clamping process, the bottom of the directional rod 801 is provided with a pulley 802, the pulley 802 is in sliding contact with a connecting block 807 in the lower mold 6, thereby driving the movement of a movable rod 805 and a moving plate 804. The two ends of the movable rod 805 are respectively fixedly connected to the connecting block 807 and the moving plate 804, and the top rod 810 is driven to move upward by the sliding mechanism, thereby driving the automobile air conditioner panel to be ejected from the top of the lower mold 6 by the ejection plate 811.
[0025] Through the cooperative work of the above structure, when the hydraulic cylinder 3 drives the upper mold 5 to move upward, the pulley 802 is in contact with the connecting block 807 and triggers the movement of the automatic ejection device. The cooperation of the movable rod 805, the moving plate 804 and the top rod 810 drives the ejection plate 811 to automatically eject the air conditioner panel, without manual operation, reduces the manual intervention time, and improves the production efficiency. And the ejection mechanism does not need to use an additional driving source, but uses the opening and closing of the mold to drive, so that the mold is more compact, greatly improving the use flexibility of the device.
[0026] The buffer assembly includes two U-shaped frames 701, which are respectively fixedly connected to the front and rear sides of the lower mold 6, the inside of the U-shaped frame 701 is fixedly connected with a fixed rod 702, the outside of the fixed rod 702 is sleeved with two first springs 706, the outside of the fixed rod 702 is slidingly connected with two sliding blocks 703, the top of the sliding block 703 is hingedly connected with a hinge rod 705, and the top end of the hinge rod 705 is hingedly connected with a contact plate 704. One end of the fixed rod 702 is fixedly connected with the outside of the sliding block 703, and the other end of the fixed rod 702 is fixedly connected with the inner wall of the U-shaped frame 701.
[0027] Specifically, the buffer assembly includes two U-shaped frames 701, which are fixedly connected to the front and rear sides of the lower die 6, respectively. The U-shaped frames 701 serve as supports and provide a stable mounting base for other components of the buffer assembly. When the upper die 5 approaches the closing die state, the bottom of the upper die 5 first contacts the outer surface of the contact plate 704. As the upper die 5 continues to move downward, the contact plate 704 begins to be pressed by the upper die 5, causing the articulated rod 705 to swing. Since the articulated rod 705 is hinged to the slider 703, the swinging of the articulated rod 705 drives the slider 703 to slide outward, thereby stretching the external first spring 706. The first spring 706 generates elastic potential energy after being stretched, which can effectively absorb the impact force during the closing of the upper die 5 and the lower die 6. When the upper die 5 and the lower die 6 almost contact, the impact force is transmitted to the first spring 706 through the articulated rod 705 and the slider 703, and is absorbed and buffered by the elastic deformation of the spring. In this way, the buffer assembly not only effectively disperses the impact force, but also converts part of the impact force into elastic potential energy of the spring, thereby reducing the mechanical stress on the mold assembly and avoiding the loss or failure of mold parts due to long-term impact load. Ultimately, the design of the buffer assembly ensures the stability and long-term durability of the mold, improving the reliability of the mold in high-frequency production processes.
[0028] The top of the mounting base plate 1 is fixedly mounted with a top plate 2, and the top of the top plate 2 is mounted with a hydraulic cylinder 3, and the output end of the hydraulic cylinder 3 is fixedly connected to the top of the upper die 5.
[0029] The left and right sides of the top of the upper die 5 are fixedly connected with guide rods 4, and the top ends of the guide rods 4 penetrate through the outer sides of the top plate 2 and extend to the outside thereof.
[0030] Specifically, the hydraulic cylinder 3 serves as a driving source and is mounted on the top of the top plate 2. The output end of the hydraulic cylinder 3 is fixedly connected to the top of the upper die 5 through mechanical connection. When the hydraulic cylinder 3 is started, by controlling the flow of hydraulic oil, the piston of the hydraulic cylinder 3 will move downward, thereby driving the upper die 5 to move downward along a specific path. In this process, the distance between the upper die 5 and the lower die 6 gradually decreases, and finally the closing die state with the lower die 6 is achieved. At this time, the upper die 5 and the lower die 6 are in close contact, forming a closed state of the mold, which ensures that the molding material in the mold is correctly pressed and molded.
[0031] Specifically, the guide rods 4 ensure the stability of the upper die 5 during movement, thereby ensuring the stability of the upper die 5 and the lower die 6 during the closing process.
[0032] Working principle: when using the device, first, start the hydraulic cylinder 3 to drive the upper die 5 to move downward, so that the upper die 5 and the lower die 6 are closed, at this time, the guide rod 4 moves along the through hole in the inner wall of the top plate 2, under the limiting action of the guide rod 4, the upper die 5 and the lower die 6 can be normally closed, and high precision in the mold closing process is ensured;
[0033] In addition, when the upper die 5 moves downward, the directional rod 801 moves synchronously, at this time, the pulley 802 at the bottom of the directional rod 801 contacts the outer surface of the connecting block 807, and drives the connecting block 807 to move outward until the pulley 802 extends into the inner bottom wall of the installation cavity 803, when the upper die 5 and the lower die 6 are about to contact, the bottom of the upper die 5 will first contact the outer surface of the contact plate 704, so that the top end of the hinged rod 705 swings, at this time, under the traction of the hinged rod 705, the sliding block 703 moves outward, so that the first spring 706 is stretched, and the impact force generated in the closing process of the upper die 5 and the lower die 6 is converted into the elastic potential energy of the first spring 706 for energy dissipation, so as to ensure the service life of the mold, after the closing is completed, the injection liquid is injected into the top forming cavity of the lower die 6, and after cooling and forming, the automobile air conditioner panel is formed, at this time, the output end of the hydraulic cylinder 3 contracts to drive the upper die 5 to move upward, so that the directional rod 801 and the pulley 802 at the bottom move synchronously, when the pulley 802 contacts the inclined surface of the connecting block 807, at this time, the movable rod 805 and the moving plate 804 move leftward, when the moving plate 804 moves, the fixed block 809 moves along the inner wall of the sliding groove 808, so that the top rod 810 and the ejection plate 811 move upward, and the ejection plate 811 ejects the automobile air conditioner panel in the forming cavity from the top of the lower die 6, without manual ejection, the time of manual intervention is reduced.
[0034] Finally, it should be pointed out that: the above only describes the preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
