Description

Technical Field

[0001] This utility model relates to the field of cement mortar test mold technology, specifically a waterproof device for cement mortar test molds. Background Technology

[0002] In the field of building materials quality testing and research, cement mortar molds are indispensable tools for conducting key performance tests such as cement mortar strength tests. Accurately measuring various performance indicators of cement mortar is crucial for evaluating cement quality and ensuring the safety and durability of building projects. During the curing process of cement mortar molds, many small water droplets will condense on the top of the mold, easily dripping onto the mold surface and thus affecting the mold's performance indicators.

[0003] Chinese patent with publication number CN217046881U discloses a waterproof device for the treatment and curing of cement mortar strength specimens before demolding. This patent uses a horizontal baffle located above the specimen mold to prevent water droplets in the curing chamber from falling onto the cement mortar in the specimen mold state, thus ensuring the appearance quality and compaction quality of the cement mortar specimens during the curing process.

[0004] Before cement mortar solidifies, the evaporated water floats upwards. In the aforementioned patent, the horizontal baffle is located directly above the cement mortar, which causes water vapor to adhere to the lower surface of the horizontal baffle and condense into small water droplets. There are still cases where water droplets fall onto the cement mortar, affecting the performance indicators of the test mold. Utility Model Content

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-5 This utility model provides a waterproof device for a cement mortar test mold, including a mold base 100. A mold cavity 101 is formed on the surface of the mold base 100. A U-shaped plate 102 is disposed inside the mold cavity 101. Lifting plates 103 are installed at both ends of the U-shaped plate 102. Installation grooves 104 are formed on both sides of the upper surface of the mold base 100. A lifting mechanism 200 is installed inside the installation grooves 104 to lift the lifting plates 103 upwards. A top plate 105 is provided on the top of the mold base 100. A water collection trough 106 is installed on the lower surface of the top plate 105 via a translation mechanism 300. A scraper 107 is installed inside the water collection trough 106, with the upper end of the scraper 107 contacting the lower surface of the top plate 105.

[0028] In use, cement mortar is first poured into the mold cavity 101, ensuring it fully fills the interior. Then, the mold base 100 is placed in a constant-temperature curing chamber for curing until completely solidified. During this process, water vapor evaporates from the cement mortar, rising and condensing into small water droplets on the lower surface of the top plate 105. At this point, the translation mechanism 300 moves the water collection tank 106 horizontally, allowing the scraper 107 to scrape off the water droplets condensed on the top wall of the top plate 105 and collect them in the water collection tank 106. This prevents water droplets from falling onto the cement mortar inside the mold cavity 101 and affecting the performance of the mold. After the cement mortar has solidified, the lifting mechanism 200 and the drive mechanism 400 work together to raise the mold cavity 101 a certain distance. At this point, the mold is no longer stuck to the inner wall of the mold cavity 101, allowing it to be easily removed, thus achieving rapid demolding and improving operational efficiency.

[0029] Preferably, the lifting mechanism 200 includes a first threaded rod 201 with a pair of reverse threads rotatably mounted inside the mounting groove 104. A first drive block 202 is mounted on each of the two reverse threads of the first threaded rod 201, and the first drive block 202 is slidably connected to the inner wall of the mounting groove 104. A first inclined surface 203 is provided at the upper end of the first drive block 202, and both ends of the lifting plate 103 are provided with second inclined surfaces 204 that match the first inclined surface 203. The outer surface of the mold base 100 is provided with a drive mechanism 400 that simultaneously engages with both sets of lifting mechanisms 200.

[0030] When the drive mechanism 400 drives the first threaded rod 201 to rotate, it can drive the two first drive blocks 202 to move closer or further away along the length of the first threaded rod 201. When the two first drive blocks 202 move closer to each other, their first inclined surfaces 203 press against the second inclined surfaces 204 of the lifting plate 103, thereby driving the lifting plate 103 to move upward. The solidified mold is then lifted a certain distance by the U-shaped plate 102 so that it is no longer stuck to the inner wall of the mold cavity 101. Then, both hands are inserted under the two lifting plates 103 respectively to lift them upward.

[0031] Preferably, the translation mechanism 300 includes two first side plates 301 mounted on the lower surface of the top plate 105 and located on both sides thereon. A second threaded rod 302 is rotatably mounted between the two first side plates 301. A second drive block 303 is mounted on the outer surface of the second threaded rod 302, and the top of the second drive block 303 is connected to the lower surface of the water collection tank 106. A motor 304 is mounted on the outer surface of one of the first side plates 301, and the end of the output shaft of the motor 304 is connected to the second threaded rod 302.

[0032] When the motor 304 is started, it drives the second threaded rod 302 to rotate, which in turn drives the second drive block 303 to move along its length, thereby achieving the purpose of driving the water collection tank 106 to move horizontally. During the translation of the water collection tank 106, the scraper 107 scrapes off the small water droplets on the top wall of the top plate 105 and drops them into the water collection tank 106, thereby preventing water droplets from falling into the cement mortar in the mold cavity 101 and affecting the performance indicators of the trial mold. Furthermore, the material of the contact part between the top of the scraper 107 and the top plate 105 is silicone, which can reduce the wear between the scraper 107 and the top plate 105 and can better scrape off the water droplets.

[0033] Preferably, the drive mechanism 400 includes two second side plates 401 mounted on the outer surface of the mold base 100, a rotating shaft 402 rotatably mounted between the two second side plates 401, two worm gears 403 mounted on the outer surface of the rotating shaft 402, and the ends of the two first threaded rods 201 extending to the outside of the mold base 100 and mounted with worm wheels 404, the worm gears 403 and worm wheels 404 meshing and connected.

[0034] When the rotating shaft 402 is rotated, it can drive the two worm gears 403 to rotate simultaneously. Since the worm gears 403 and worm wheels 404 mesh with each other, it can achieve the purpose of driving the two first threaded rods 201 to rotate simultaneously. Furthermore, the worm gears 403 and worm wheels 404 have a high transmission ratio, which can complete the demolding more effortlessly.

[0035] Preferably, a number of uprights 500 are installed on the upper surface of the mold base 100, and a number of through holes 502 matching the uprights 500 are opened on the surface of the top plate 105. The outer surface of the uprights 500 is provided with a shoulder 501.

[0036] By inserting the upright 500 into the through hole 502, the bottom of the top plate 105 is supported by the shoulder 501, thereby achieving the purpose of quick assembly and disassembly of the top plate 105.

[0037] Preferably, a battery 600 is mounted on the outer surface of the first side plate 301 on which the motor 304 is mounted, and the battery 600 is electrically connected to the motor 304.

[0038] The battery 600 provides power to the motor 304, enabling the water collection tank 106 to move horizontally without the need for an external power source, thus offering high flexibility.

[0039] Preferably, two third side plates 700 are installed on the lower surface of the top plate 105, and a slide rod 701 is installed in front of the two third side plates 700. A sliding sleeve 702 is slidably installed on the outer surface of the slide rod 701, and the top of the sliding sleeve 702 is connected to the lower surface of the water collection tank 106.

[0040] The sliding rod 701 and the sliding sleeve 702 provide a limiting function for the water collection tank 106, so that the water collection tank 106 can move more smoothly, ensuring that the scraper 107 is evenly attached to the top wall of the top plate 105 to scrape off the water droplets.

[0041] Preferably, a handle 800 is installed at the end of the rotating shaft 402, and the outer surface of the handle 800 is provided with an anti-slip layer.

[0042] With the handle 800, the rotating shaft 402 can be rotated more easily and effortlessly for demolding.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
