Description

Technical Field

[0001] The utility model belongs to the field of cement mortar molding, and in particular relates to a cement mortar test mold device. Background Art

[0002] The cement mortar test mold is a special tool used to form cement strength test blocks. The test blocks formed by the test mold can be used to conduct compressive strength, flexural strength and other physical property tests of cement, mortar and concrete.

[0003] A cover plate is arranged above the mold cavity of the cement mortar test mold. When the mold cavity is filled with cement, the cover plate is controlled to seal the upper end of the mold cavity to flatten the upper surface of the cement, thereby completing the preparation of the cement test block. However, after the lower surface of the cover plate contacts the cement, some cement will inevitably remain on the surface. In order to ensure the molding quality of the subsequent test blocks, the lower surface of the cover plate needs to be cleaned after each molding. For this purpose, a cement mortar test mold device is proposed. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a cement mortar test mold device comprises a workbench 1, and two templates 2 that can be synchronously approached are arranged on the upper end of the workbench 1, and the templates 2 are "concave" shaped. The two templates 2 can be fitted together to form a square mold cavity, so as to facilitate the preparation of cement test blocks; when the cement test block is formed, the demoulding action can be realized by controlling the two templates 2 to synchronously slide in opposite directions, so as to facilitate the removal of the cement test block;

[0026] In this embodiment, two hydraulic cylinders 3 are arranged on the workbench 1 to drive the two templates 2 to slide synchronously in opposite directions, and ensure that the mold closing positions of the two templates 2 remain consistent each time, so as to facilitate the alignment of the square mold cavity formed by the mold closing with the cover plate.

[0027] A cover plate assembly 4 is provided at the upper end of the workbench 1. Figure 2 As shown, the cover assembly 4 includes a slidable mounting frame 41, and the sliding direction is parallel to the sliding direction of the template 2. A first cylinder 44 is provided on the mounting frame 41 to drive the cover 45 to rise and fall. The descending cover 45 can act on the square mold cavity and flatten and compact the cement therein. It is worth mentioning that the mounting frame 41 is position-adjusted along the sliding direction of the template 2, which can facilitate the alignment of the square mold cavity and the cover 45 to a certain extent.

[0028] In this embodiment, the mounting frame 41 is slidably connected to the workbench 1, and the sliding direction is parallel to the sliding direction of the template 2. Two fixing plates 42 are fixed to the upper end of the workbench 1. A screw rod 43 is rotatably connected between the two fixing plates 42. The screw rod 43 penetrates the mounting frame 41 and is threadedly connected thereto. By arranging a motor on one of the fixing plates 42 to drive the screw rod 43 to rotate, the mounting frame 41 can be driven to slide.

[0029] Furthermore, in order to ensure that the mounting bracket 41 remains stable after position adjustment, the screw rod 43 needs to have a self-locking property, that is, the thread lead angle of the screw rod 43 is smaller than the equivalent friction angle.

[0030] Of course, the method of driving the mounting frame 41 to slide includes but is not limited to the structure such as the screw rod 43 in this embodiment. In some embodiments, the mounting frame 41 can also be directly driven to slide by setting a telescopic rod on the workbench 1.

[0031] A fixing frame 5 is fixed on the upper end of the workbench 1. Figure 3 As shown, the upper end of the fixing frame 5 is provided with an inclined scraper 51. After the cement test block is formed, the cover plate 45 is controlled to rise to the highest point, and the mounting frame 41 slides so that the edge of the cover plate 45 reaches the scraper 51. Then, the cover plate 45 is controlled to descend so that its lower surface contacts the scraper 51. Then, the mounting frame 41 is controlled to slide again so that the scraper 51 can scrape the cement adhered to the lower surface of the cover plate 45, thereby ensuring the subsequent cement test block forming quality.

[0032] A storage box 6 is fixed on the fixing frame 5, and the storage box 6 can store cement scraped from the lower surface of the cover plate 45; and in the present embodiment, the storage box 6 and the fixing frame 5 are fixed by bolt connection to facilitate the disassembly of the storage box 6, so as to unload the cement stored therein.

[0033] A lifting assembly 7 is provided at the lower end of the workbench 1, and the lifting assembly 7 can scrape and clean the concrete adhering to the inner walls of the two templates;

[0034] like Figure 4 and Figure 5 As shown, the lifting assembly 7 includes a connecting plate 71 fixed to the lower end of the workbench 1, two second cylinders 72 are fixed on the connecting plate 71, and a lifting plate 73 is fixed on the driving shaft of the two second cylinders 72 respectively, and two clearance grooves 11 are provided on the workbench 1; when the two templates 2 move away from each other and reach the farthest point, under the drive of the second cylinder 72, the two lifting plates 73 can respectively pass through the two clearance grooves 11 and slide in cooperation with the inner cavities of the two templates 2 respectively, so that the inner walls of the two templates 2 can be scraped and cleaned.

[0035] Working principle:

[0036] By arranging two concave templates 2 that can be synchronously approached at the upper end of the workbench 1, a square mold cavity is formed when the mold is closed, and a mounting frame 41 that can slide along the sliding direction of the template is arranged on the workbench 1, and a cover plate 45 that can be lifted and lowered is arranged on the mounting frame 41. When the cover plate 45 descends, it can act on the cement in the square mold cavity to compact and flatten the cement inside, and by arranging an inclined scraper 51 on the fixing frame 5, when the cover plate 45 slides with the mounting frame 41, the scraper 51 can contact the lower end surface of the cover plate 45, so that the cement adhered to the lower surface of the cover plate 45 can be scraped off, thereby ensuring the subsequent cement test block molding quality. By arranging a lifting component 7 below the workbench 1, two lifting plates 73 that can be lifted and lowered are arranged in the lifting component 7. When the two templates 2 move away from each other and reach the farthest point, the two lifting plates 73 can slide in cooperation with the inner cavity of the two templates 2 respectively, so that the inner walls of the two templates 2 can be scraped and cleaned.
