Description
Technical Field
[0001] This application relates to the field of mold technology, and in particular to a sand and gravel crushing mold. Background Technology
[0002] The sand and gravel crushing mold, also known as the aggregate crushing value test mold, is a special test device used to determine the crushing ability of coarse aggregates under continuously increasing loads. It is an indispensable key quality inspection tool in road engineering, construction engineering and building materials laboratories. Its test result - crushing value - is one of the core indicators for measuring the mechanical properties of aggregates and evaluating their engineering applicability. Although the sand and gravel crushing mold is a simple device, it plays a crucial "gatekeeper" role in ensuring the quality of basic materials for construction projects and ensuring the safety and durability of engineering structures. However, the existing sand and gravel crushing mold still has certain defects. While traditional sand and gravel crushing molds can be used effectively, they typically can only handle samples of one shape or size. During the pressing process, misalignment or tilting can easily occur between the crushing block and the mold, resulting in uneven pressure distribution, which affects the repeatability and accuracy of experimental data. Furthermore, traditional crushing blocks may bend, jump, or even burst out when subjected to rapid or uneven pressure, threatening the safety of operators and often causing problems for users. Utility Model Content

A first pressure sensor 2 is embedded and fixedly installed inside the square mold 1. An upper mold 3 is provided on the top surface of the square mold 1. A polygonal pressing groove 4 is provided on the upper mold 3. A first positioning block 5 and a second positioning block 6 are provided on the polygonal pressing groove 4. The first positioning block 5 and the second positioning block 6 are set by pins and are fixedly installed by connecting bolts 7. A polygonal pressing block 8 is provided on the bottom surface of the first positioning block 5 and the second positioning block 6, and the polygonal pressing block 8 is slidably connected to the polygonal pressing groove 4.
[0020] A first pressure post 9 is provided above the first positioning block 5 and the second positioning block 6, and the first pressure post 9 is slidably connected through the center of the first positioning block 5 and the second positioning block 6.
[0021] The first pressure column 9 is provided with four sets of first protective plates 10 in a circular array. The first protective plates 10 are provided with first fixing bolts 11, and the first protective plates 10 are fixed to the first pressure column 9 by the first fixing bolts 11. The specific steps are as follows: This application will have the following effect; When users need to crush sand and gravel into square stone cakes, workers use square mold 1 to crush the sand and gravel. First, it needs to be assembled. Square mold 1 is placed on a flat surface, and upper mold 3 is placed on top of square mold 1. Then, the first positioning block 5 and the second positioning block 6 are fixed by connecting bolts 7. Since the first positioning block 5 and the second positioning block 6 are set with pins, the first positioning block 5 and the second positioning block 6 are fixed more stably. Then, the first protective plate 10 is fixedly installed on the first pressure column 9 by the first fixing bolt 11. Since there are four sets of first protective plates 10, the four sets of first protective plates 10 can protect the first pressure column 9 and the square mold 1 at the bottom, preventing the crushed stone from falling out when crushing the sand and gravel. Users crush the sand and gravel by pressing down on the first pressure column 9. When the first pressure column 9 presses down on the sand and gravel, the first pressure sensor 2 set inside the square mold 1 monitors the downward pressure of the first pressure column 9 in real time. Terminology Explanation: like Figures 4 to 5 As shown, a second pressure sensor 13 is embedded and fixedly installed inside the circular mold 12, and an auxiliary cylinder 14 is provided above the circular mold 12.

The second protective plate 16 and the second pressure column 15 are fixedly installed by the second fixing bolt 17, and four sets of the second protective plate 16 and the second fixing bolt 17 are arranged in a circular array about the center of the second pressure column 15. The specific steps are as follows: This application will have the following effect; When users need to crush sand and gravel into round stone cakes, the staff uses a round mold 12 to crush the sand and gravel. First, it needs to be assembled. The round mold 12 is placed on a flat surface, and the auxiliary cylinder 14 is sleeved on top of the round mold 12. Then, the second protective plate 16 is fixedly installed on the second pressure column 15 by the second fixing bolt 17. Since there are four sets of second protective plates 16, the four sets of second protective plates 16 can protect the second pressure column 15 and the round mold 12 at the bottom, preventing the crushed stone from falling out when crushing the sand and gravel. The user crushes the sand and gravel by pressing down on the second pressure column 15. When the second pressure column 15 presses down on the sand and gravel, the second pressure sensor 13 installed inside the round mold 12 monitors the downward pressure of the second pressure column 15 in real time. Working principle: When the user needs to crush sand and gravel into square stone cakes, the staff uses square mold 1 to crush the sand and gravel. First, it needs to be assembled. Square mold 1 is placed on a flat surface, and upper mold 3 is placed on top of square mold 1. Then, the first positioning block 5 and the second positioning block 6 are fixed by connecting bolts 7. Since the first positioning block 5 and the second positioning block 6 are set with pins, the first positioning block 5 and the second positioning block 6 are fixed more stably. Then, the first protective plate 10 is fixedly installed on the first pressure column 9 by the first fixing bolt 11. Since there are four sets of first protective plates 10, the four sets of first protective plates 10 can protect the first pressure column 9 and the square mold 1 at the bottom, preventing the crushed stone from falling out when crushing the sand and gravel. The user crushes the sand and gravel by pressing down the first pressure column 9. When the first pressure column 9 presses down on the sand and gravel, the first pressure sensor 2 set inside the square mold 1 monitors the downward pressure of the first pressure column 9 in real time. When users need to crush sand and gravel into round stone cakes, workers use a round mold 12 to crush the sand and gravel. First, it needs to be assembled. The round mold 12 is placed on a flat surface, and the auxiliary cylinder 14 is sleeved on top of the round mold 12. Then, the second protective plate 16 is fixedly installed on the second pressure column 15 by the second fixing bolt 17. Since there are four sets of second protective plates 16, the four sets of second protective plates 16 can protect the second pressure column 15 and the round mold 12 at the bottom, preventing the crushed stone from falling out when crushing the sand and gravel. Users crush the sand and gravel by pressing down on the second pressure column 15. When the second pressure column 15 presses down on the sand and gravel, the second pressure sensor 13 installed inside the round mold 12 monitors the downward pressure of the second pressure column 15 in real time.
