DETAILED DESCRIPTION

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] like Figure 1 、 Figure 2 As shown, an easy-to-release concrete test mold includes a base 1, a boss 2, multiple panels 3, a mounting seat 4, a slider 5 and a driving mechanism 6.

[0030] like Figure 1 、 Figure 2 As shown, the base 1 is horizontally arranged on the table, and the boss 2 is arranged on the upper end surface of the base 1. A plurality of panels 3 are vertically arranged on the base 1 and surround the boss 2, and form a mold cavity 7 with an upper end opening with the boss 2 for pouring concrete slurry.

[0031] like Figure 1 、 Figure 2 As shown, the mounting seat 4 is arranged on the outer wall of the enclosure 3, the slider 5 is connected to the mounting seat 4, and slides in the surrounding directions along the center position of the base 1, and the driving mechanism 6 is used to control the synchronous sliding of multiple sliders 5 so that the enclosure 3 approaches or leaves the boss 2 at the same time.

[0032] When a concrete test block needs to be produced, the driving mechanism 6 controls the multiple sliders 5 to move closer to each other. At this time, the sliders 5 drive the mounting base 4 and the enclosure 3 to move synchronously, so that the enclosure 3 gradually approaches the boss 2. When the inner wall of the enclosure 3 hits the outer wall of the boss 2, the side walls of all the enclosures 3 hit each other, forming a mold cavity 7.

[0033] Then, concrete slurry is poured into the mold cavity 7. After the concrete solidifies and takes shape, the driving mechanism 6 is used to control the multiple sliders 5 to move away from each other. At this time, the sliders 5 drive the mounting seat 4 and the enclosure 3 to move synchronously, so that the enclosure 3 gradually moves away from the boss 2, realizing the rapid separation of the test piece and the test mold, and achieving the effect of automatic demoulding and rapid demoulding.

[0034] like Figure 1 、 Figure 2 As shown, the driving mechanism 6 includes a turntable 61, a handle 62, a guide rod 63 and a locking member 8. The turntable 61 is rotatably connected to the inside of the base 1, and the handle 62 is provided on the outer wall of the turntable 61 and passes through the side wall of the base 1.

[0035] like Figure 1 、 Figure 2 As shown, the guide rod 63 is vertically arranged on the lower end surface of the slider 5, the base 1 is provided with a strip hole 64 arranged along the sliding direction of the slider 5 and for the guide rod 63 to slide, and the turntable 61 is provided with an arc-shaped guide hole 65 for the guide rod 63 to be embedded.

[0036] like Figure 1 、 Figure 2 As shown, locking member 8 is used to secure turntable 61 and comprises a locking rod 81, a pull ring 82, and a tension spring 83. Locking rod 81 is vertically slidably connected to base 1, and turntable 61 is provided with a locking hole 84 for receiving locking rod 81. Pull ring 82 is provided at the upper end of locking rod 81, and tension spring 83 is provided on the outer wall of locking rod 81 and located between base 1 and pull ring 82.

[0037] When the slider 5 needs to be moved, the handle 62 is used to rotate the turntable 61. At this time, under the cooperation of the guide rod 63 and the guide hole 65, the guide rod 63 drives the slider 5 to slide in the strip hole 64, and the slider 5 drives the mounting seat 4 and the enclosure 3 to move synchronously. After the enclosure 3 surrounds the mold cavity 7, the locking rod 81 is controlled to be inserted into the locking hole 84 to fix the turntable 61 and the enclosure 3, thereby fixing the turntable 61 and the enclosure 3 for the production of the test piece.

[0038] On the contrary, when demoulding is required, the locking rod 81 is pulled upward to control the handle 62 to drive the turntable 61 to move in the opposite direction, so that the enclosure 3 is separated from the test piece, thereby achieving automatic demoulding.

[0039] like Figure 3 、 Figure 4 As shown, the boss 2 includes a circular platform 21 and a square platform 22, and the enclosure 3 includes an arcuate side panel 31 and a plane side panel 32. The circular platform 21 and the arcuate side panel 31 match each other, and the square platform 22 and the plane side panel 32 match each other.

[0040] like Figure 3 、 Figure 4As shown, the lower end surfaces of the circular table 21 and the square table 22 are provided with a clamping block 23, the base 1 is provided with a clamping groove 11 for the clamping block 23 to be embedded, the outer wall of the clamping block 23 is provided with a locking ring 24, and the inner wall of the clamping groove 11 is provided with a locking groove 12 for the locking ring 24 to be embedded, so as to realize convenient and quick fixation of the circular table 21 and the square table 22.

[0041] like Figure 3 、 Figure 4 As shown, the mounting seat 4 is respectively arranged on the outer wall of the arc-shaped side panel 31 and the flat side panel 32, the mounting seat 4 is provided with a hook 41, and the slider 5 is provided with a hole 51 for the hook 41 to pass through, so as to realize convenient and quick fixation of the arc-shaped side panel 31 and the flat side panel 32.

[0042] Therefore, by setting the circular table plate 21 and the arc-shaped side plate 31 together, a cylindrical mold cavity 7 is formed, and by setting the square table plate 22 and the flat side plate 32 together, a square mold cavity 7 is formed. Cylindrical specimens or square specimens can be produced according to needs to meet different usage requirements.

[0043] like Figure 3 、 Figure 4 As shown, the inner side walls of the curved side panels 31 and the flat side panels 32 are both provided with ceramic linings 33 to reduce the adhesion between the concrete and the enclosure 3, thereby achieving convenient demoulding of the concrete specimen.

[0044] like Figure 3 、 Figure 4 As shown, a sealing gasket 34 is provided on the side where the arcuate side plate 31 and the plane side plate 32 are close to each other, so as to increase the sealing between the adjacent arcuate side plates 31 and the plane side plates 32, avoid slurry leakage, and ensure the stable production of the specimen.

[0045] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
