Detailed Description of the Embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment

[0029] A processing mold for SMC deep groove ribs, as Figure 1 shown, includes a support assembly, a die-casting assembly, and a demolding assembly; the support assembly includes a support plate 1, a fixing plate 7, and a bottom plate 11. The support plate 1 is connected to the bottom plate 11 through the lower support column 10, and the support plate 1 is connected to the fixing plate 7 through the upper support column 3;

[0030] As shown Figure 2 in the figure, the die-casting assembly includes a hydraulic cylinder 6, an upper die head 5 and a lower die head 12; the hydraulic cylinder 6 is fixedly connected to the bottom of the fixed plate 7, and the upper die head 5 is fixedly connected to the bottom of the hydraulic cylinder 6; the lower die head 12 includes a lower left die head 1201 and a lower right die head 1202, and the lower left die head 1201 and the lower right die head 1202 are symmetrically arranged on the mounting plate; the lower left die head 1201 and the lower right die head 1202 are connected by a connecting device, and the connecting device is used to separate or close the lower left die head 1201 and the lower right die head 1202;

[0031] At the front side of the middle part of the support plate 1, there is a blanking port 15; the demoulding assembly includes a telescopic rod 21, a suction cup 20 and an air pump 19; as Figure 4 shown in the figure, the bottom of the telescopic rod 21 is connected to the bottom plate 11, the suction cup 20 is connected to the top of the telescopic rod 21, and the suction cup 20 faces the blanking port 15; the air pump 19 is arranged on the bottom plate 11, and the air pump 19 is connected to the suction cup 20.

[0032] Specifically, during use, the lower left die head 1201 and the lower right die head 1202 are closed into the lower die head 12 through the connecting device. The lower die head 12 has an inner cavity, and the SMC composite material is laid in the inner cavity. The hydraulic cylinder 6 is started to make the upper die head 5 enter the inner cavity of the lower die head 12 and extrude the SMC composite material. The bottom of the upper die head 5 has a cavity, and the SMC composite material enters the cavity of the upper die head 5 after being extruded. Subsequently, a rib in an inverted T-shaped structure is formed between the upper die head 5 and the lower die head 12. After the rib die-casting is completed, the hydraulic cylinder 6 is controlled to move upward a small distance so that the upper die head 5 no longer exerts pressure on the lower die head 12. The lower left die head 1201 and the lower right die head 1202 are separated by the connecting device, so that the blanking port 15 directly faces the bottom of the rib. The telescopic rod 21 is started and the telescopic rod 21 is controlled to extend. The telescopic rod 21 pushes the suction cup 20 upward, and the suction cup 20 contacts the bottom of the rib after passing through the blanking port 15. The air pump 19 is started, and the air pump 19 extracts air to form a negative pressure at the suction cup 20 and makes the suction cup 20 suck the rib. Subsequently, the hydraulic cylinder 6 can be controlled to drive the upper die head 5 to move to the top dead center. During the upward movement of the upper die head 5, the rib is pulled by the suction cup 20, so that demoulding is completed. Finally, the rib between the lower left die head 1201 and the lower right die head 1202 can be taken away. The entire demoulding process is convenient and fast, and the next die-casting can be continued after the demoulding work is completed.

[0033] In a preferred embodiment, as Figure 1As shown in the figure, a reinforcing frame 4 is fixedly connected between the upper support columns 3 on both sides of the support plate 1. The reinforcing frame 4 is of an X-shaped structure. The reinforcing frame 4 is used to connect the two upper support columns 3 and ensure the stability of the upper support columns 3. Since the hydraulic cylinder 6 is connected to the fixed plate 7, during the die-casting process, the upper support columns 3 are subjected to a large force, and the strength of the upper support columns 3 needs to be enhanced. By adding the X-shaped reinforcing frame 4, the strength of the upper support columns 3 can be effectively increased.

[0034] In a preferred embodiment, as Figure 2 shown, wing plates 8 are fixedly connected to both sides of the upper die head 5. A guide post 9 is fixedly connected between the support plate 1 and the fixed plate 7. The guide post 9 is located on both sides of the upper die head 5. The wing plates 8 are slidably connected to the guide post 9. The wing plates 8 are used to increase the stability of the upper die head 5. During use, the hydraulic cylinder 6 drives the upper die head 5 to move up and down. The wing plates 8 on both sides of the upper die head 5 slide on the guide post 9, so that the upper die head 5 can be lifted and lowered stably. After ensuring the stability of the upper die head 5, the quality of the pressed ribs can be guaranteed.

[0035] In a preferred embodiment, as Figure 3 shown, the connecting device includes a bidirectional lead screw 18. A left connecting block 26 is fixedly connected to the rear side of the lower left die head 1201, and a right connecting block 26 is fixedly connected to the rear side of the lower right die head 1202; a fixed block 25 is fixedly connected to the support plate 1; the bidirectional lead screw 18 is rotatably connected to the fixed block 25. The lower left die head 1201 and the lower right die head 1202 are respectively threadedly connected to both sides of the bidirectional lead screw 18 through the left connecting block 26 and the right connecting block 26. Among them, the bidirectional lead screw 18 is a lead screw with opposite thread directions on both sides. Specifically, during use, the bidirectional lead screw 18 is rotated, and the bidirectional lead screw 18 drives the left connecting block 26 and the right connecting block 26 on both sides to approach or move away from each other. The approaching left connecting block 26 and right connecting block 26 drive the lower left die head 1201 and the lower right die head 1202 to approach or move away from each other, so as to realize the separation or closing of the lower left die head 1201 and the lower right die head 1202. The fixed block 25 is used to install the bidirectional lead screw 18 and provide support for the lead screw to ensure that the bidirectional lead screw 18 can rotate stably. At the same time, the bidirectional lead screw 18 has the ability of self-locking, that is, after adjusting the positions of the lower left die head 1201 and the lower right die head 1202, the positions of the lower left die head 1201 and the lower right die head 1202 will not move, which can effectively improve the stability of the entire device.

[0036] In a preferred embodiment, as Figure 3As shown in the figure, a driven wheel 24 is fixedly connected to one side of the bidirectional lead screw 18; a driving motor 2 is connected to the support plate 1, and a driving wheel 22 is fixedly connected to the output shaft of the driving motor 2. The driving wheel 22 is connected to the driven wheel 24. Further optimized, the driving wheel 22 and the driven wheel 24 are connected by a toothed belt 23. Setting the driving motor 2 can facilitate the rotation of the bidirectional lead screw 18. During use, the bidirectional lead screw 18 can be rotated by starting the driving motor 2. More specifically, the driving motor 2 can be a servo motor. When the servo motor is used in cooperation with an encoder or other position feedback devices, the number of rotation turns of the servo motor can be controlled according to the set position or angle. By changing the position command, the motor can be controlled to move to the specified position, thereby controlling the number of rotation turns of the motor. The number of rotation turns of the bidirectional lead screw 18 is controlled by controlling the number of rotation turns of the driving motor 2. By controlling the number of rotation turns of the lead screw, the moving distance between the lower left die head 1201 and the lower right die head 1202 can be controlled. Using the toothed belt 23 to connect the driving wheel 22 and the driven wheel 24 is to ensure the stability of the connection. The toothed belt 23 has the advantage of not being prone to slipping and can stably transmit power, thereby controlling the stable rotation of the bidirectional lead screw 18.

[0037] In a preferred embodiment, as Figure 3 shown, positioning plates 17 are fixedly connected to both the left and right sides of the support plate 1. Guide rods 16 are fixedly connected to the sides of the lower left die head 1201 and the lower right die head 1202. The guide rods 16 on the lower left die head 1201 and the lower right die head 1202 are respectively movably connected to the adjacent positioning plates 17. The positioning plates 17 are used to limit the positions of the lower left die head 1201 and the lower right die head 1202, preventing the lower left die head 1201 or the lower right die from moving too far. The guide rods 16 on the sides of the lower left die head 1201 and the lower right die head 1202 are used to stabilize the positions of the lower left die head 1201 and the lower right die head 1202, ensuring the stability of the movement of the lower left die head 1201 and the lower right die head 1202, enabling the lower left die head 1201 and the lower right die head 1202 to move smoothly to the left or right, and ensuring stable demolding.

[0038] In a preferred embodiment, as Figure 1 shown, a blanking groove 13 is provided on the front side of the middle part of the support plate 1. In actual use, a collection box can be placed below the blanking groove 13. The blanking groove 13 is used to facilitate the collection of the rib strips after processing. During use, the rib strips can be dropped by pushing the demolded parts into the blanking groove 13. Further optimized, the front side of the material positioning opening 15 is communicated with the blanking groove 13. Through this design, it is convenient to push the processed rib strips into the blanking groove 13, thereby facilitating the collection of the processed rib strips.

[0039] In a preferred embodiment, as Figure 1As shown, the blanking port 15 is a long strip structure. A guide rail 14 is fixedly connected to the bottom plate 11. A guide groove is provided on the guide rail 14. Sliders are fixedly connected to both sides of the bottom of the telescopic rod 21, and the sliders are slidably connected in the guide groove. An electric push rod 27 is also provided on the bottom plate 11. One end of the electric push rod 27 is connected to the telescopic rod 21, and the other end is connected to the bottom plate 11. The sliders at the bottom of the telescopic rod 21 are used to ensure that the telescopic rod 21 can move stably on the guide rail 14. Specifically, during actual use, after the rib demolding is completed, the electric push rod 27 is started. The electric push rod 27 drives the telescopic rod 21 to move. The telescopic rod 21 drives the rib to move through the suction cup 20 at the top. When the rib moves to the front side of the support plate 1, the suction cup 20 is released. In this way, the rib can be removed from between the lower left die head 1201 and the lower right die head 1202, which is convenient for collecting the processed ribs and can effectively improve the processing efficiency.
