Description

Technical Field

[0001] This utility model relates to the field of manhole cover processing technology, and in particular to a forming mold for manhole cover processing. Background Technology

[0002] Manhole covers are used to cover deep wells on roads or in homes to prevent people or objects from falling in. During the manufacturing process, concrete is usually poured into a lower mold, and then an upper mold is placed on top of the lower mold. After the concrete has set, the upper and lower molds are removed to obtain the finished manhole cover.

[0003] In existing technology, after the manhole cover has solidified in the mold, the lower mold is lifted to separate it from the manhole cover. However, during solidification, the manhole cover tends to adhere to the inner wall of the lower mold. To separate the manhole cover from the lower mold, the operator usually uses tools such as a hammer to strike the side wall of the lower mold, causing it to vibrate and separate from the manhole cover. However, when striking the lower mold, the manhole cover inside the lower mold is easily damaged by the vibration. To address this issue, we have designed a molding die for manhole cover processing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A forming mold for processing manhole covers includes a placement platform 1, a lower mold 5 and an upper mold 7. The lower mold 5 is placed on the placement platform 1. A lifting mechanism is provided at the top of the bottom end of the placement platform 1. The lifting mechanism passes through the placement platform 1 and is fixedly connected to the side wall of the lower mold 5. The lifting mechanism includes an electric push rod 2 fixedly installed on the top of the bottom end of the placement platform 1. A sliding plate 3 is fixedly installed at the telescopic end of the electric push rod 2. The sliding plate 3 is slidably connected to the placement platform 1. Two mounting brackets 4 are fixedly installed on the top of the sliding plate 3. Both mounting brackets 4 pass through the placement platform 1 and are slidably connected to it. Both mounting brackets 4 are fixedly connected to the side wall of the lower mold 5.

[0025] A vertical plate 15 is fixedly installed on the top of the placement platform 1. A fixing plate 16 is fixedly installed on the front side wall of the vertical plate 15. A hydraulic cylinder 6 is fixedly installed on the bottom of the fixing plate 16. The upper mold 7 is fixedly installed on the telescopic end of the hydraulic cylinder 6. A smoothing mechanism is provided on the front side wall of the vertical plate 15. The smoothing mechanism includes an electric slide rail 8 fixedly installed on the front side wall of the vertical plate 15. An electric slider 19 is slidably connected in the electric slide rail 8. A second connecting rod 17 is fixedly installed on the front side wall of the electric slider 19. A scraper 18 is fixedly installed at the bottom end of the second connecting rod 17. The bottom of the scraper 18 is on the same horizontal plane as the top of the lower mold 5. With the setting of the smoothing mechanism, when the lower mold 5 is filled with concrete, the concrete above the top of the lower mold 5 can be automatically smoothed, saving the operator from manually holding the trowel to smooth the concrete and reducing the workload of the operator.

[0026] A sliding block 20 is slidably connected to the placement platform 1. A fixing mechanism is provided between the bottom of the placement platform 1 and the bottom of the sliding block 20. The fixing mechanism includes a locking screw 9 threadedly connected to the placement platform 1. A slot 21 is provided at the bottom of the sliding block 20. The top end of the locking screw 9 extends into the slot 21 and abuts against its inner top. Through the setting of the fixing mechanism, when the well cover in the lower mold 5 is pushed out, the baffle 13 on the fixing rod 12 can be fixed.

[0027] The top of the sliding block 20 is provided with an ejection mechanism, which includes a first connecting rod 10 fixedly installed on the top of the sliding block 20. A horizontal plate 11 is fixedly installed at the top of the first connecting rod 10, and a fixed rod 12 is fixedly installed at the bottom of the horizontal plate 11. A pull rod 14 is fixedly installed on the front side wall of the fixed rod 12. With the pull rod 14 on the front side wall of the fixed rod 12, when the baffle 13 on the fixed rod 12 is moved, the operator can pull it with the pull rod 14, which makes it convenient for the operator to move the baffle 13. The bottom end of the fixed rod 12 is fixedly installed with the baffle 13. With the setting of the lifting mechanism, the fixing mechanism and the ejection mechanism, after the well cover is produced, it can quickly separate the well cover that is attached to the lower mold 5 from the lower mold 5, and will not damage the well cover during separation.

[0028] The functional principle of this utility model can be explained through the following operation methods:

[0029] When manhole cover production is required, the operator first puts concrete into the lower mold 5. After the lower mold 5 is filled with concrete, the operator starts the electric slide rail 8. The electric slide rail 8 drives the electric slider 19 to slide to the right. The electric slider 19 drives the scraper 18 to slide to the right through the second connecting rod 17. When the scraper 18 slides to the right, the bottom of the scraper 18 scrapes the concrete above the top of the lower mold 5 and moves it to the right, smoothing the concrete in the lower mold 5. When the scraper 18 slides to the right side of the lower mold 5, the operator adds concrete to the recessed area in the lower mold 5. Then the operator starts the electric slide rail 8 to drive the scraper 18 to slide to the left and reset. At this time, the scraper 18 smooths the concrete in the lower mold 5 again. After the scraper 18 resets, the operator starts the hydraulic cylinder 6 to extend and drive the upper mold 7 to move downward, so that the bottom of the upper mold 7 abuts against the top of the lower mold 5.

[0030] After the concrete in the lower mold 5 has completely solidified, the operator activates the hydraulic cylinder 6 to retract, causing the upper mold 7 to return to its original position. Then, the operator pulls the pull rod 14, which moves the baffle 13 on the fixed rod 12 to the left. The fixed rod 12, through the horizontal plate 11, moves the sliding block 20 on the first connecting rod 10 to the left. When the sliding block 20 reaches the leftmost position, the center of the baffle 13 is directly above the center of the manhole cover in the lower mold 5. Then, the operator rotates the locking screw 9, causing the top of the locking screw 9 to enter the slot 21 and abut against its inner top. At this time, the sliding block 20 is in a fixed state, which in turn fixes the baffle 13. Then, the electric push rod 2 is activated to extend. The electric push rod 2 moves the lower mold 5 upward through the mounting bracket 4 on the sliding plate 3. The manhole cover in the lower mold 5 is blocked by the bottom of the baffle 13 and cannot move upward. Finally, the lower mold 5 continues to rise and detaches from the manhole cover. Then, the manhole cover can be removed from the placement platform 1.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
