The force-bearing surface is narrow, the demoulding work is effective, and the test piece is easily damaged by hitting the ground when demoulding at a high place, which affects the subsequent experimental work. Utility Model Content

[0004] The utility model aims to provide a demoulding device for an anti-seepage test mold to solve the above problems.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides a demoulding device for an anti-permeability test mold, comprising: a demoulding device frame, a jack arranged on the demoulding device frame, a support plate arranged on the demoulding device frame, a drop-off hole arranged on the support plate, and a shock-absorbing part arranged on the demoulding device frame;

[0008] The jack can push the cushion block to press down the anti-seepage test block, so that the anti-seepage test block falls off the anti-seepage test mold and is collected by the shock-absorbing part after being damped.

[0009] Further, the shock absorbing part includes two connecting rods mirror-imaged on both sides of the demoulding device frame, two direction-changing abutting parts sleeved outside one end of the two connecting rods, and a plurality of first springs arranged between each of the direction-changing abutting parts and each of the connecting rods;

[0010] When the anti-permeability test block falls off, it can rub against the two direction-changing abutting parts, so that the two direction-changing abutting parts compress a plurality of the first springs along the two connecting rods.

[0011] Furthermore, the direction-changing resistance portion includes a movable sleeve sleeved on the outside of one end of the connecting rod, and a triangular block arranged at one end of the movable sleeve;

[0012] The inclined surface of the triangular block gradually slopes downward from a direction approaching the movable sleeve toward a direction away from the movable sleeve, and the inclined surface can contact the anti-seepage test block.

[0013] Furthermore, the shock absorbing part further comprises two elastic ropes arranged in an X-shaped pattern at different heights on the demoulding device frame, and a sand storage box arranged at the lower ends of the two elastic ropes;

[0014] When the anti-seepage test block falls off, it can press down the two elastic ropes to deform and then fall into the sand storage box.

[0015] Furthermore, the support plate is provided with four positioning components;

[0016] The lower end of the impermeability test mold is provided with a frame plate, and the frame plate is provided with four positioning holes;

[0021] Further, the positioning assembly includes an annular groove arranged on the support plate and co-centric with the support column, and a second spring arranged in the annular groove;

[0022] The second spring is disposed at the periphery of the support column;

[0023] The frame plate can compress the second spring so that the anti-seepage test mold can be placed in a shock-absorbing manner.

[0024] Compared with the prior art, the embodiment of the utility model has the following beneficial effects: compared with the prior art, the upper and lower end surfaces of the cushion block are in synchronous contact with the lower end of the jack and the upper end of the anti-permeability test block respectively, so that the anti-permeability test block can be separated under the load under the influence of the cushion block's own load-bearing effect, and the jack's downward push work allows the cushion block to act on the anti-permeability test block as a force transition carrier, so that the anti-permeability test block expands the force surface and more quickly separates from the anti-permeability test mold, shortening its working timeliness;

[0025] After the anti-seepage test block is separated from the test mold of the anti-seepage instrument, it can be collected by the shock-absorbing part on the lower falling trajectory, which ensures that the anti-seepage test block is not damaged by impact after demoulding, and also maintains the quality of the anti-seepage test block, so that the accuracy of subsequent testing work of the anti-seepage test block is not affected.

[0033] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0034] like Figure 1-4 As shown, a demoulding device for an impermeability test mold comprises: a demoulding device frame 1 for supporting force, a jack 2 arranged on the demoulding device frame 1, the jack 2 is ejected upward, which is a prior art and will not be further described here, a support plate 3 arranged on the demoulding device frame 1, a drop-off hole 4 arranged on the support plate 3, and a shock absorbing part 5 arranged on the demoulding device frame 1;

[0035] The vertical central axes of the jack 2, the drop-off hole 4 and the shock-absorbing part 5 are collinear;

[0036] The anti-seepage test mold demoulding device also includes an anti-seepage test mold 6 that can be set on the support plate 3, an anti-seepage test block 7 set inside the anti-seepage test mold 6, and the size of the drop-out hole 4 is larger than the anti-seepage test block 7, so that the anti-seepage test block 7 can be separated from the anti-seepage test mold 6 without obstruction.

[0037] and a cushion block 8 that can be placed on the upper end of the impermeability test block 7 and contact the end of the jack 2. In one embodiment, the jack 2 may not be connected to the demoulding device frame 1 but may be centrally placed on the cushion block 8. The jack 2 pushes up the demoulding device frame 1 and allows the cushion block 8 to move downward relatively. The cushion block 8 may be made of cast iron with a diameter of 100 mm and a thickness of 35 mm. The jack 2 is 100 kN.

[0038] The jack 2 can push the cushion block 8 to press down the anti-seepage test block 7, so that the anti-seepage test block 7 falls off the anti-seepage test mold 6 and is collected by the shock-absorbing part 5. Specifically, in the prior art, the demoulding work of the anti-seepage test block 7 from the anti-seepage test mold 6 is long in time, small in force surface, low in efficiency, and easy to cause damage to the anti-seepage test block 7. Compared with the prior art, the upper and lower end surfaces of the cushion block 8 are in synchronous contact with the lower end of the jack 2 and the upper end of the anti-seepage test block 7 respectively, so that the anti-seepage test block 7 can be in the cushion block 8 itself The load-bearing test block 7 is detached under the influence of the load effect, and the downward pushing work of the jack 2 allows the cushion block 8 to act on the anti-seepage test block 7 as a force transition carrier, so that the anti-seepage test block 7 can expand the force surface and more quickly detach from the anti-seepage test mold 6, shortening the timeliness of its work; and after the anti-seepage test block 7 detaches from the anti-seepage test mold 6, it can be collected by the shock-absorbing part 5 on the lower falling trajectory by shock absorption, which ensures that the anti-seepage test block 7 is not damaged by impact after demolding, and also maintains the quality of the anti-seepage test block 7, so that the accuracy of subsequent detection work of the anti-seepage test block 7 is not affected.

[0039] Optionally, the shock absorbing part 5 includes two connecting rods 51 mirror-mounted on both sides of the demoulding device frame 1, two direction-changing abutting parts 52 sleeved outside one end of the two connecting rods 51, and a plurality of first springs 53 arranged between each of the direction-changing abutting parts 52 and each of the connecting rods 51;

[0040] When the anti-seepage test block 7 falls off, it can rub the two redirecting resistance parts 52, so that the two redirecting resistance parts 52 compress a number of the first springs 53 along the two connecting rods 51. Specifically, after the anti-seepage test block 7 is separated from the anti-seepage test mold 6, it contacts the sides of the two redirecting resistance parts 52. As the descending distance of the anti-seepage test block 7 increases, the contact area between the anti-seepage test block 7 and the two redirecting resistance parts 52 is also gradually increasing, thereby increasing the compression degree of the first springs 53 of the corresponding position number. During the descent of the anti-seepage test block 7, the friction resistance between the anti-seepage test block 7 and the redirecting resistance parts 52 also has a process from small to large, thereby slowing down the descending force of the anti-seepage test block 7, thereby protecting the anti-seepage test block 7. When the anti-seepage test block 7 is completely separated from the two redirecting resistance parts 52, the first spring 53 is reset from the compressed state, thereby ensuring the repeated position change of the redirecting resistance parts 52.

[0041] Optionally, the direction-changing resistance portion 52 includes a movable sleeve 521 sleeved on the outside of one end of the connecting rod 51, and a triangular block 522 arranged at one end of the movable sleeve 521;

[0042] The inclined surface of the triangular block 522 gradually tilts downward from the direction approaching the movable sleeve 521 toward the direction away from the movable sleeve, and its inclined surface can contact the anti-seepage test block 7. Specifically, the inclined surface of the triangular block 522 serves as a friction surface with the anti-seepage test block 7 when it falls, so that the force effect of the anti-seepage test block 7 and the movable sleeve 521 is smoother, and the movable movement of the movable sleeve 521 toward the connecting rod 51 is convenient. The movable sleeve 521 can drive the triangular block 522 to move radially along the connecting rod 51, ensuring that the telescopic trajectory of the first spring 53 will not be offset, and also making the degree of directional unloading of the falling force of the anti-seepage test block 7 accurate.

[0043] Optionally, the shock absorbing part 5 further includes two elastic ropes 54 arranged in an X-shaped staggered manner at different heights on the demoulding device frame 1, and a sand storage box 55 arranged at the lower ends of the two elastic ropes 54;

[0044] When the anti-seepage test block 7 falls off, it can press down the two elastic ropes 54 to deform and then fall into the sand storage box 55. Specifically, the elastic rope 54 has toughness and elasticity. After the anti-seepage test block 7 reaches the area of ​​the two elastic ropes 54 after the friction and shock absorption measures of the triangular block 522 in the previous stage, the two elastic ropes 54 are elastically pressed down by the pressure of the anti-seepage test block 7 and contact the sand in the sand storage box 55 together, so that the protection angle and range of the anti-seepage test block 7 are wider, the unloading effect is balanced, and the quality of the protection work for the anti-seepage test block 7 is improved.

[0045] Optionally, four positioning components 9 are provided on the support plate 3;

[0046] The lower end of the impermeability tester test mold 6 is provided with a frame plate 10, and the frame plate 10 is provided with four positioning holes 11;

[0047] When the impermeability test mold 6 is placed down on the support plate 3, the four positioning holes 11 can be combined with the four positioning components 9. Specifically, during the production process of the impermeability test mold 6, the frame plate 10 faces upward and the impermeability test mold 6 faces downward. When demolding, the impermeability test mold 6 is inverted. At this time, the frame plate 10 faces downward. Based on this combination of positioning components 9 and positioning holes 11, the disengagement exit of the impermeability test block 7 corresponds to the center of the disengagement hole 4, which ensures that during the demolding of the impermeability test block 7, the position of the impermeability test mold 6 will not be offset to block the disengagement state of the impermeability test block 7 with the disengagement hole 4.

[0048] Optionally, the positioning assembly 9 includes a support column 91 disposed on the support plate 3, and a support cone 92 rotatably disposed on the support column 91;

[0049] The outer diameter of the support column 91 is equal to the aperture of the positioning hole 11, and the diameter of the upper end surface of the support cone 92 is smaller than the aperture of the positioning hole 11;

[0050] The frame plate 10 can drive the positioning hole 11 to be inserted into the support cone 92 and the support column 91 in sequence. Specifically, the upper end area of ​​the support cone 92 is small and the lower end area is large, and the end with the large area is connected to the support column 91. The positioning hole 11 is first inserted into the support cone 92, and is fitted with the outer wall of the support column 91 by its guiding effect. In this state, the frame plate 10 can no longer shake back and forth or left and right, which ensures a good positioning effect of the anti-permeability test mold 6 in the pre-demolding state, and also makes the positioning work more convenient.

[0051] Optionally, the positioning assembly 9 includes an annular groove 93 disposed on the support plate 3 and co-centered with the support column 91, and a second spring 94 disposed in the annular groove 93;

[0052] The second spring 94 is disposed at the periphery of the support column 91;

[0053] The frame plate 10 can compress the second spring 94 so that the anti-seepage test mold 6 can be placed in a shock-absorbing manner. Specifically, the annular groove 93 is colinear with the central axis of the support column 91. The annular groove 93 provides an accommodating space for the second spring 94. After the second spring 94 is installed, as the frame plate 10 is pressed downward, the downward vibration amplitude of the anti-seepage test mold 6 is slowed down, and the vibration frequency of the anti-seepage test mold 6 is increased, which is conducive to better detachment of the anti-seepage test block 7.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Specifically, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
