Description

Technical Field

[0001] This utility model relates to the technical field of concrete test mold demolding equipment, specifically an automatic demolding equipment for concrete test molds. Background Technology

[0002] Currently, the demolding of concrete test blocks largely relies on manual operation. Operators need to manually disassemble the mold and tap the test block to achieve demolding, which has the following technical drawbacks:

[0003] Low efficiency: Manual demolding can only process 1-2 sets of test molds at a time. For demolding of 100x100x100 triple test molds, the time required for each set is relatively long, making it difficult to meet the needs of batch testing scenarios; Poor safety: Manual hammering can easily cause test blocks to break and test molds to fly, posing a safety hazard of cuts and injuries to operators' hands; High risk of test block damage: Uneven manual force can easily lead to edge and corner damage and surface cracking of test blocks, affecting the accuracy of subsequent compressive strength and other test data. An automatic demolding device for concrete test molds has been invented to solve the above problems. Utility Model Content

[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] Example 1

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: an automatic demolding device for concrete test molds, including a frame 1, a flipping mechanism 2, a clamping mechanism 3, a limiting mechanism 4, and a lifting mechanism 5. The flipping mechanism 2 includes a fixed plate 201, a flipping frame 202, a buffer pad 203, and a first cylinder 204. The front and rear of the flipping frame 202 are rotatably connected to the fixed plate 201 via shafts. A buffer pad 203 for buffering is provided at the bottom of the flipping frame 202. The first cylinder 204 is rotatably connected to the inside of the frame 1 via shafts. The clamping mechanism 3 includes a second cylinder 301, an adjusting plate 302, a buffer spring 303, an air nozzle 304, a limiting cylinder 305, and a lifting mechanism 5. The trial mold 306 and the adjusting plate 302 are respectively equipped with a buffer spring 303 and the movable end of the second cylinder 301. One end of the buffer spring 303 is equipped with a limiting cylinder 305 that abuts against the trial mold 306. The end of the limiting cylinder 305 away from the trial mold 306 is provided with an air nozzle 304 for ventilation. The limiting mechanism 4 includes a third cylinder 401, a mating block 402 and a limiting baffle 403. The top of the mating block 402 is equipped with a limiting baffle 403 for blocking the limiting. The lifting mechanism 5 includes a fourth cylinder 501, a lifting frame 502 and a photoelectric switch 503. One side of the lifting frame 502 is provided with a photoelectric switch 503 for detection.

[0026] Specifically, to facilitate the flipping adjustment of the flipping frame 202, the buffer pad 203 is set to buffer the flipping frame 202 during reset when it completes a single demolding cycle, thus preventing the flipping frame 202 from rigidly colliding with the fixed plate 201.

[0027] Please see Figures 1 to 6 The movable end of the first cylinder 204 is rotatably connected to the tilting frame 202, and the bottom of the buffer pad 203 abuts against the fixed plate 201.

[0028] Specifically, after the flipping frame 202 is flipped, its position is aligned with the lifting frame 502, which facilitates the demolding of the test block inside the test mold 306.

[0029] Please see Figures 1 to 6 The fixed end of the second cylinder 301 is mounted on the tilting frame 202, and the position of the tilting frame 202 corresponds to the position of the lifting frame 502.

[0030] Specifically, the position of the test mold 306 is conveniently restricted by the cooperation of the limiting cylinder 305 and the flipping frame 202, and the air nozzle 304 facilitates air passage. The gas is blown into the gap between the test block and the inner wall of the test mold 306, which facilitates the demolding of the test block.

[0031] Please see Figures 1 to 3 The trial mold 306 is placed inside the flipping frame 202, and one side of the trial mold 306 has an air hole corresponding to the position of the limiting cylinder 305 and the air nozzle 304.

[0032] Specifically, the setting of the limiting baffle 403 is to conveniently restrict the position of the test block inside the test mold 306 and prevent the test block inside the test mold 306 from falling off when flipping.

[0033] Please see Figures 2 to 4 The fixed ends of the mating block 402 and the third cylinder 401 are rotatably connected to the tilting frame 202 via shafts, and the movable end of the third cylinder 401 is rotatably connected to the mating block 402 via shafts.

[0034] Specifically, the lifting frame 502 is adjusted to facilitate the support of test blocks that fall into the test mold 306 and to move the test blocks downwards.

[0035] Please see Figures 1 to 6 The fourth cylinder 501 is installed inside the frame 1, and the lifting frame 502 is installed at the movable end of the fourth cylinder 501.

[0036] In use, the external handling robot receives instructions from the PLC controller and precisely places the 100×100×100 triple mold 306 to be demolded into the interior of the flipping frame 202. When the position of the mold 306 is restricted, the second cylinder 301 of the clamping mechanism 3 operates, and the movable end of the second cylinder 301 retracts, driving the adjusting plate 302 and the limiting cylinder 305 to move, so that the limiting cylinder 305 abuts against the mold 306. Through the cooperation of the limiting cylinder 305 and the flipping frame 202, the position of the mold 306 is easily clamped and restricted. The buffer spring 303 is set to avoid rigid clamping of the mold 306 and avoid damage to the mold 306. At this time, the position of the limiting cylinder 305 is... Corresponding to the position of the air holes opened on the test mold 306, the third cylinder 401 of the limiting structure 4 is activated, and the movable end of the third cylinder 401 extends, causing the mating block 402 to rotate around the rotational connection between the mating block 402 and the flipping frame 202. This facilitates the limiting baffle 403 to move in an arc trajectory to the position corresponding to the test block position inside the test mold 306, preventing the test block inside the test mold 306 from falling out during subsequent flipping. After flipping and moving the test mold 306 and the position of the test block, the first cylinder 204 is activated, and the movable end of the first cylinder 204 extends, causing the flipping frame 202 to rotate around the rotational connection between the flipping frame 202 and the fixed plate 201, so that the test mold 306... Position 6 moves above the lifting frame 502 of the lifting mechanism 5. The fourth cylinder 501 operates, and its movable end extends, driving the lifting frame 502 upward to approach the test mold 306. Then, the movable end of the third cylinder 401 retracts, causing the limiting baffle 403 to reset and no longer block the position of the test block inside the test mold 306. Gas is injected through the air nozzle 304, allowing the gas to reach the limiting cylinder 305 and enter the interior of the test mold 306 through the air hole on the test mold 306, blowing air into the gap between the test block and the inner wall of the test mold 306 to facilitate the test block's detachment. If the photoelectric switch 503 detects that the test block has detached from the test mold 306 and fallen onto the lifting frame 502, A "successful demolding" signal is sent to the controller, which then controls the fourth cylinder 501 to operate, causing the lifting frame 502 to move the test block downwards and transport it to the robot's unloading height. If the photoelectric switch 503 does not detect the test block detaching, the controller automatically extends the blowing time of the air nozzle 304. If the test block is still not detected after extending the blowing time, the controller triggers an audible and visual alarm and displays a "test block stuck" fault on the operation screen, prompting manual inspection of the fit between the mold 306 and the test block. Subsequently, the robot removes the test block, and after the flipping frame 202 resets, the robot removes the mold 306, completing a single cycle. The equipment then enters the next operation waiting state, improving its practicality.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
