[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] like Figs. 1 to 6 As shown, an automatic demolding device for engineering material test blocks includes a test block mold 1, a demolding device 2, a limiting device 3, and a conveying device 4. The demolding device 2 is located behind the conveying device 4, and the limiting device 3 is provided at the connection between the demolding device 2 and the conveying device 4. The test block mold 1 is conveyed on the conveying device 4. The demolding device 2 includes a hydraulic cylinder 201, a piston rod 202, and a demolding module 203. The hydraulic cylinder 201 is fixed to the rear of the conveying device 4, and the piston rod 202 is assembled on the front side inside the hydraulic cylinder 201. The front end of the piston rod 202 is fixedly connected to the demolding module 203 that matches the test block mold 1. After the engineering material test block has been cured to the demolding time, the test block mold 1 is placed on the conveying device 4, and the limiting device 3 cooperates with the conveying device 4 to demold. This invention solves the problem that the current method of demolding engineering material test blocks mainly relies on manual operation, which is inefficient, wastes time and effort, and is prone to damage due to improper operation, affecting the accuracy of test results.

[0041] In the embodiment, the conveying device 4 comprises a mold conveying belt 401, a test block conveying belt 402 and a center wheel 403. The mold conveying belt 401 and the test block conveying belt 402 are arranged in parallel on the front side of the demolding device 2, and the test block conveying belt 402 is located on the front side of the mold conveying belt 401. The mold conveying belt 401 and the test block conveying belt 402 are both equipped with the center wheel 403 inside, and the mold conveying belt 401 and the test block conveying belt 402 are both driven by the center motor 304. The mold conveying belt 401 is used to convey the test block mold 1, so as to facilitate conveying the test block mold 1 into the working range of the limiting device 3 and the demolding device 2. The test block conveying belt 402 is used to convey the test block demolded from the test block mold 1. The center motor 304 can control the conveying direction and the conveying speed of the mold conveying belt 401 and the test block conveying belt 402.

[0042] In the embodiment, the limiting device 3 comprises a limiter 303, a motor 304, an extension rod 305, a sliding groove 306, a gear 307 and a fixed rod 308. The limiter 303 is arranged in multiple groups and arranged in a conical distribution on the front side of the demolding device 2. Adjacent two groups of limiters 303 are respectively located on both sides of the mold conveying belt 401. The lower side of the right two groups of limiters 303 is provided with the extension rod 305. The bottom of the extension rod 305 is fixedly provided with a T-shaped rack plate. The left side of the extension rod 305 is provided with the fixed rod 308. The fixed rod 308 is internally provided with the sliding groove 306. The rack plate at the bottom of the extension rod 305 is clamped into the sliding groove 306 and is in sliding connection with the fixed rod 308. The lower side of the rack plate is in meshing transmission connection with the gear 307. The gear 307 is driven by the motor 304. The limiting device 3 arranged can accurately position and fix the test block mold 1 conveyed on the mold conveying belt 401, so as to prevent the test block mold 1 from sliding and offsetting, thereby ensuring the accuracy and stability of demolding. When the test block mold 1 is conveyed to the front side of the demolding device 2, the limiting device 3 starts to work. The limiter 303 can limit and fix the test block mold 1 from both sides, so as to fix the test block mold 1 in the working range of the demolding device 2. At the same time, the motor 304 drives the gear 307 to rotate. The gear 307 is in meshing transmission connection with the rack plate at the bottom of the extension rod 305, so as to drive the extension rod 305 to slide in the sliding groove 306. By adjusting the position of the extension rod 305, the position of the extension rod 305 can be accurately adjusted, so that the extension rod 305 is blocked at the right end of the test block mold 1, thereby preventing the test block mold 1 from moving excessively.

[0043] In this embodiment, the limiting device 3 further includes two sets of positioning plates 301. The two sets of positioning plates 301 are symmetrically arranged on both sides of the mold conveyor belt 401, and the positioning plates 301 are located to the left of the demolding device 2. Multiple sets of ball bearings 302 are embedded on the contact surfaces of the two sets of positioning plates 301 and the mold conveyor belt 401, and the ball bearings 302 roll against the mold conveyor belt 401. The two sets of positioning plates 301 limit the movement range of the test block mold 1, guiding the test block mold 1 to move along the mold conveyor belt 401 and accurately enter the limiting range of the limiter 303, ensuring that the mold does not deviate from the predetermined trajectory during conveying. The design of multiple sets of ball bearings 302 reduces the frictional resistance between the positioning plates 301 and the mold conveyor belt 401, thereby reducing wear between the positioning plates 301 and the mold conveyor belt 401.

[0044] In this embodiment, the test block mold 1 includes a mold shell 101, a mold base 102, and a base handle 103. The mold shell 101 is placed on the mold conveyor belt 401. A detachable mold base 102 is provided through the bottom of the mold shell 101, and a base handle 103 is fitted to the left end of the mold base 102. The test block mold 1 is used to contain and cure engineering material test blocks, and cooperates with the demolding device 2 during the demolding process to achieve smooth demolding of the test blocks. During the curing stage of the engineering material test blocks, the test blocks are formed inside the mold shell 101. The mold base 102 fits tightly with the mold shell 101 to ensure that the test blocks are fully cured. When the test blocks have cured to the demolding time, the operator removes the mold base 102 through the base handle 103 and places the mold shell 101 on the mold conveyor belt 401. As the conveyor belt moves, the mold shell 101 is transported to the working range of the demolding device 2, and then cooperates with the demolding device 2 to achieve smooth demolding of the test blocks.

[0045] In this embodiment, the test block mold 1 and the release module 203 are plastic products, the positioning plate 301, the ball bearing 302, the limiter 303, the telescopic rod 305, and the fixing rod 308 are steel products, and the mold conveyor belt 401 and the test block conveyor belt 402 are rubber products.

[0046] In this embodiment, the front end of the release module 203 is a detachable block assembly structure, and its rear end is fixedly connected to the piston rod 202. The specifications of the release module 203 are adapted to the internal structure of the test block mold 1. This design allows the release module 203 to be adjusted and combined according to the internal structure of the test block mold 1, enabling the release module 203 to adapt to test block molds 1 of different specifications and shapes, thus improving the versatility of the equipment.
