[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling in. They can be classified by material into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. When processing manhole covers, a molding machine is used to solidify molten iron into a manhole cover through two sets of molds on the molding machine.

[0003] Existing manhole cover molding processes require opening the mold and unloading the material after molding. However, the unloading operation still requires manual labor, which is time-consuming and labor-intensive, reducing the efficiency of demolding and unloading. To address this, we propose a molding device for manhole cover processing. Utility Model Content

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 5 This utility model provides a technical solution: a forming mold device for manhole cover processing, including a base 11, a frame 3 fastened to the top of the base 11, and an upper mold 10 connected to the bottom of the frame 3. The frame 3 is a U-shaped frame with the opening facing downwards. The upper mold 10 is located directly below the frame 3, and a first electric push rod 12 is vertically connected to the frame 3. The telescopic end of the first electric push rod 12 is fixedly connected to the upper mold 10, and a plurality of first guide rods 13 penetrating the frame 3 are vertically connected to the top of the upper mold 10. Figure 1 , 2 As shown, the push of the first electric push rod 12 can cause the upper mold 10 to slide up and down within the frame 3. Under the guidance of the first guide rod 13, the upper mold 10 can be kept to slide stably at the bottom of the frame 3, ensuring the normal use of the device.

[0022] As shown in Figures 1, 2, and 3, a lower mold 7 is connected to the top of the base 11 and located directly below the upper mold 10. A demolding mechanism is provided inside the lower mold 7. The demolding mechanism includes a chamber 25 located inside the base 11. A connecting seat 23 is horizontally arranged inside the chamber 25, and a push rod 4 is vertically connected to the top of the connecting seat 23. A through groove 5 is provided through the lower mold 7, and the push rod 4 is slidably connected in the through groove 5. A second electric push rod 21 is vertically connected inside the chamber 25. A push plate 20 is coaxially connected to the telescopic end of the second electric push rod 21. The push plate 20 and the bottom of the connecting seat 23 abut against each other. Under the combined pressing action of the upper mold 10 and the lower mold 7, the manhole cover can be molded. After the mold is formed, the push plate 20 can be moved upward by the push rod 21 and the manhole cover can be quickly demolded by the push rod 4, which greatly facilitates the demolding operation.

[0023] Meanwhile, to ensure that the connecting seat 23 slides up and down stably, multiple second guide rods 22 are vertically connected inside the chamber 25, penetrating the connecting seat 23. A return spring 24 is tightly fixed between the top of the connecting seat 23 and the top surface inside the chamber 25, and the return spring 24 and the second guide rod 22 are coaxially arranged. Under the elastic force of the return spring 24, the push rod 4 can be quickly reset.

[0024] like Figure 1 , 4 As shown in Figure 5, transport tables 18 are symmetrically connected to both sides of the base 11. Each transport table 18 is equipped with multiple transport rollers 17 that are rotatably connected to it. The top of the transport table 18 is symmetrically provided with strip grooves 15. The strip grooves 15 located on the same straight line are connected to each other. Supports 6 are slidably arranged in the strip grooves 15. In order to ensure that the supports 6 can slide and adjust synchronously, screws 14 are rotatably connected in each strip groove 15. The supports 6 and screws 14 are threaded together. A sprocket 19 is coaxially connected to one end of each of the two screws 14. The two sprockets 19 are connected to each other by a chain. A second motor 16 is coaxially connected to one of the screws 14. By controlling the rotation of the second motor 16, the two sprockets 19 can be driven to rotate synchronously, thereby realizing the synchronous rotation of the two screws 14.

[0025] Meanwhile, a lifting mechanism is symmetrically arranged on the top of the support 6. The telescopic end of the lifting mechanism is fixedly fitted with a support plate 9, and the bottom of the lifting mechanism is connected to the support 6 through a rotating mechanism. The rotating mechanism includes a first motor 1 fixedly fitted on the top of the support 6. A second gear 30 is coaxially connected to the output end of the first motor 1. A connecting shaft 28 is rotatably connected to the top of the support 6, and a first gear 29 is coaxially connected to the connecting shaft 28. The first gear 29 and the second gear 30 are meshed together. The lifting mechanism includes a third electric push rod 27 fixedly fitted on the top of the connecting shaft 28. The support plate 9 and the telescopic end of the third electric push rod 27 are connected. A mounting housing 8 is fixedly fitted on the top of the support 6. The telescopic end of the third electric push rod 27 passes through the mounting housing 8. An opening 26 is opened on the side wall of the mounting housing 8, and the second gear 30 extends into the mounting housing 8 through the opening 26.

[0026] In summary, the molding and pressing device for manhole cover processing also includes a control box 2. The control box 2 contains a controller that connects the first motor 1, the first electric push rod 12, the second motor 16, the second electric push rod 21, the third electric push rod 27, and the controller. Simultaneously, the manhole cover ejected through the aforementioned demolding structure (…) Figure 3 (Indicated by arrow A) is located above the lower mold 7, and the screw 14 is rotated to move the support 6 to the outside of the lower mold 7. At this time, the third electric push rod 27 pushes the support plate 9 upward, and under the control of the first motor 1, it drives the support plate 9 to rotate so that it contacts the side wall of the manhole cover. Then, the position of the support plate 9 is finely adjusted by the third electric push rod 27 so that the support plate 9 can support the bottom of the manhole cover or its extended skirt structure. After the support is completed, the screw 14 rotates to move the support 6, so that the manhole cover can be moved to the transport roller 17 on the top of the transport platform 18. With the support of the transport roller 17, the pressure on the support plate 9 can be reduced, which greatly facilitates the transportation of the manhole cover and saves a lot of manpower.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
