Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment, and in particular relates to an adjustable height truncated cone test mold. Background Technology

[0002] Water resistance pressure is a key indicator characterizing the waterproofing capability of waterproofing materials. When the thickness of the waterproofing layer is no more than 5 mm, it is required to test the water resistance pressure of the coated specimen. According to the current national standard "Inorganic Waterproofing and Leak-Plugging Materials" (GB 23440-2009), when preparing the base mortar for the coating water resistance pressure test specimen, the thickness of the specimen should be reduced by about 2 mm on the corresponding water-facing or water-repellent side by adding a pad or scraping. After the specimen has cured, a coating of the corresponding thickness should be formed on the water-facing or water-repellent side by manual scraping. That is, the thickness of the coating water resistance pressure test specimen is the thickness of the base mortar specimen plus the thickness of the coating.

[0003] However, the following defects were found in actual operation: 1) The test mold is a truncated cone with a bottom, with dimensions of 70mm upper diameter, 80mm lower diameter, and 30mm height. When preparing the base mortar specimens using the standard method, the actual height of the base specimens after demolding and curing will deviate; 2) When preparing the coating on the back side of the base mortar, manual scraping cannot strictly control the coating thickness, especially when preparing a highly fluid slurry coating. This easily leads to slurry flow at the edges, resulting in inconsistent coating thickness and discrepancies between the molded specimen parameters and the predetermined parameters; 3) Because the mold is a truncated cone, it is difficult for the coating to form a uniform angle with the base mortar around the specimen; 4) The coating thickness cannot be changed according to actual needs, making it impossible to prepare specimens with coatings of different thicknesses, thus limiting its applicability; 5) The operation process is inconvenient and prone to large human errors. These problems ultimately lead to difficulties in mold assembly and leakage during the impermeability pressure test. Furthermore, inconsistent coating thickness may affect the reliability of the test results, thereby affecting the evaluation of product quality. Utility Model Content

[0004] In view of this, in order to solve the above-mentioned technical problems, this utility model proposes an adjustable height truncated cone mold, which is simple to operate, can ensure high molding accuracy and small error of the specimen, uniform thickness of the coating throughout, tight adhesion between the coating and the base mortar, and smooth connection on all sides; at the same time, it can also mold base mortar specimens of different heights, thereby meeting the needs of preparing specimens with different coating thicknesses.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An adjustable-height truncated cone mold, characterized in that it comprises:

[0007] The base is a circular plate structure with a ring of insertion grooves on its upper surface.

[0008] The assembly mold comprises multiple sets, each set including mold one and mold two; mold one has a ring of insertion protrusions at its bottom that match the insertion groove, and mold one is detachably mounted on the base; mold two is detachably assembled onto mold one; after assembly, mold one and mold two form a frustum-shaped molding cavity; the total height of mold one and mold two in each set does not exceed 30mm, wherein the height of mold two is 2-10mm.

[0009] The base, mold one, and mold two constitute a complete test mold. The height of mold one is the height of the basic mortar specimen, and the height of mold two is the thickness of the coating. The base plus mold one is used to form the basic mortar specimen, and the base plus mold one plus mold two is used to form the final coating impermeability pressure test specimen. Multiple sets of splicing molds are set up. The total height of mold one and mold two in each set is the same, but the heights of mold one and mold two are different. According to the actual situation, mold one of appropriate height is selected and installed on the base to prepare the basic mortar specimen (the height of the basic mortar specimen = 30mm - the coating thickness). Mold two is not assembled during this process. After the basic mortar specimen is formed, it is demolded, cured, and then placed back into the original mold. At this time, the corresponding mold two is assembled. The forming method is selected according to the state of the coating material. For materials with high fluidity, it can be directly poured and formed. For materials with poor fluidity, it is formed by tamping or vibration. After filling and compacting, the surface is smoothed. After the coating is completely hardened, it is demolded by directly opening the joint between mold one and the base, and then gently pushing the specimen from the top to remove the specimen from the mold.

[0010] Furthermore, the top of the first mold is provided with a ring of splicing grooves, and the bottom of the second mold is provided with a ring of splicing protrusions that are adapted to the splicing grooves.

[0011] The use of interlocking grooves and interlocking protrusions allows for quick and accurate assembly of mold one and mold two, preventing displacement.

[0012] Furthermore, the dimensions of the molding cavity are a frustum structure with a bottom diameter of 80mm and a top diameter of 70mm.

[0013] Furthermore, the height of mold two in each set of splicing molds is 2-5mm.

[0014] Furthermore, the splicing mold has four sets, and the dimensions of mold one and mold two in each set are as follows: in the first set, mold one is 28mm and mold two is 2mm; in the second set, mold one is 27mm and mold two is 3mm; in the third set, mold one is 26mm and mold two is 4mm; in the fourth set, mold one is 25mm and mold two is 5mm.

[0015] It can form coating pressure resistance test specimens with coating thicknesses of 2mm, 3mm, 4mm, and 5mm.

[0016] Furthermore, it also includes a detachable elastic rubber sleeve fitted onto the outer wall of the splicing mold.

[0017] The elastic rubber sleeve can improve the connection stability of mold one and mold two, and prevent them from separating.

[0018] Furthermore, an anti-slip layer is provided on the outer wall of the elastic rubber sleeve.

[0019] The anti-slip layer makes it easy to hold during demolding and prevents slippage.

[0020] Furthermore, the lower end face of the base is also provided with a support groove.

[0021] When demolding or moving the mold, you can insert your fingers into the support groove to stabilize the base, while holding the elastic rubber sleeve with your other hand to stabilize the entire mold.

[0022] Compared with the prior art, the adjustable-height truncated cone test mold of this utility model has the following advantages:

[0023] (1) The adjustable height truncated cone test mold structure of this utility model is reasonably designed and easy to operate. It can accurately form the basic mortar test specimen by assembling the base and mold one, and then accurately form the final coating anti-seepage pressure test specimen by assembling the base, mold one and mold two. The test specimen has high forming accuracy and small error, uniform coating thickness, tight bonding between the coating and the basic mortar, and smooth connection around the perimeter, ensuring that the subsequent anti-seepage and waterproof test can be carried out smoothly and the test results are reliable.

[0024] (2) The adjustable height truncated cone test mold of this utility model is equipped with multiple sets of assembly molds, which can form basic mortar test specimens of different heights, meet the needs of preparing coating test specimens of different thicknesses, and has a wide range of applications.
