Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for compaction experiments, and in particular to a hydraulic demolding device for stable demolding. Background Technology

[0002] A hydraulic demolding device is used in conjunction with a multi-functional electric compactor, a Marshall electric compactor, and concrete impermeability test molds to safely and non-destructively separate molded samples (e.g., concrete test blocks, asphalt mixture test blocks) from the mold. To improve the safety, convenience, and stability of demolding, we urgently need a hydraulic demolding device that provides stable demolding.

[0003] Currently, hydraulic demolding machines mainly consist of a hydraulic lifting module and a demolding module. During demolding, the molded sample to be demolded and the mold are placed together on the hydraulic lifting module, and the hydraulic lifting module controls the molded sample and the mold to move upward. When the molded sample, the mold and the demolding module come into contact, the molded sample passes through the through hole of the demolding module and continues to move upward. The mold is blocked by the demolding module and cannot move upward. In this way, demolding (i.e., the molded sample is removed from the mold) can be achieved. However, since the molded sample to be demolded and the mold are not aligned (i.e., the axis of the molded sample, the axis of the mold and the axis of the hydraulic lifting module are not on the same axis), this operation will cause the molded sample to have difficulty passing through the through hole of the demolding module (i.e., it is blocked by the demolding module), which will affect the demolding operation of the hydraulic demolding machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the technical problem that the demolding operation of the existing hydraulic demolding machine is affected by the misalignment of the axes of the molded sample, the mold and the hydraulic lifting module, this utility model provides a hydraulic demolding machine with stable demolding. By improving the structure of the hydraulic demolding machine, it can ensure that the axes of the molded sample, the mold and the hydraulic lifting module are aligned, so as to achieve stable demolding operation of the hydraulic demolding machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hydraulic demolding device for stable demolding, comprising: a hydraulic demolding mechanism, a demolding module, and multiple adjustment mechanisms. The demolding module is located above the hydraulic demolding mechanism and has a first through hole. When the hydraulic demolding mechanism abuts against the demolding module, the hydraulic demolding mechanism and the demolding module work together to demold the molded sample. The multiple adjustment mechanisms are distributed in a ring at equal intervals outside the hydraulic demolding mechanism. Each adjustment mechanism includes: a first driving member and an adjustment block. The telescopic end of the first driving member is connected to the adjustment block. The first driving member is used to drive the adjustment block to move closer to or further away from the hydraulic demolding mechanism to adjust the position of the molded sample relative to the hydraulic demolding mechanism. The multiple adjustment mechanisms work together on the mold to make the axis of the molded sample, the axis of the mold, and the axis of the hydraulic demolding mechanism coincide.

[0006] Therefore, by setting multiple adjustment mechanisms, the positions of the molded sample and the mold relative to the hydraulic lifting mechanism can be adjusted so that the axis of the molded sample, the axis of the mold, and the axis of the hydraulic lifting mechanism coincide. Compared with the existing method of directly placing the molded sample and the mold on the hydraulic lifting platform without adjustment, this method has a simple structure and is easy to operate. During demolding, by adjusting the positions of the molded sample and the mold relative to the hydraulic lifting mechanism, the molded sample can pass through the first through hole without being blocked by the demolding module. In this way, the hydraulic demolding machine can achieve stable demolding operation, thereby improving the demolding efficiency and demolding effect of the hydraulic demolding machine.

[0007] As a further improvement to the above technical solution, it also includes: a clamping block, which is located between the hydraulic demolding mechanism and the demolding module. The clamping block has a second through hole at a position opposite to the first through hole, and a stepped portion is provided on the side of the clamping block near the hydraulic demolding mechanism. The axes of the first through hole, the second through hole, and the stepped portion coincide. Thus, during demolding, the clamping block and the hydraulic lifting mechanism jointly fix the molded sample and mold to be demolded, ensuring that the molded sample and mold will not shake during the upward process (i.e., they will not move relative to the hydraulic lifting mechanism, and the axes of the molded sample and the mold will not deviate from the axis of the hydraulic lifting mechanism). This ensures that the molded sample can pass through the second through hole and the first through hole, thereby realizing the demolding operation of the molded sample. The stepped portion engages with the mold, further limiting the mold to ensure that the molded sample and mold will not shake during the upward process.

[0008] As a further improvement to the above technical solution, it also includes: a base, the hydraulic demolding mechanism being connected to the base, the demolding module being connected to the base via a support rod, the first driving member being connected to the base, and the clamping block passing through the support rod and being slidably connected to the support rod.

[0009] As a further improvement to the above technical solution: the hydraulic demolding mechanism includes a second driving member and a demolding base. The second driving member is connected to the base, and the demolding base is installed at the telescopic end of the second driving member. The demolding base is used to place the molded sample and the mold. Thus, the second driving member can drive the demolding base to move up and down to achieve the demolding operation of the molded sample.

[0010] As a further improvement to the above technical solution: when not demolded, the clamping block is installed on the demolding module by the first locking member, and the clamping block cannot move relative to the demolding module; when demolded, the first locking member is in a loosened state, and the clamping block can slide relative to the support rod.

[0011] As a further improvement to the above technical solution: a first magnet is provided on the side of the clamping block near the hydraulic demolding mechanism, and a second magnet is provided on the side of the base near the clamping block. The magnetism of the first magnet and the magnetism of the second magnet are repulsive. Therefore, during demolding, the interaction between the first and second magnets limits the descent speed of the clamping block and the mold (i.e., the gravity of the clamping block and the mold interacts with the repulsive force of the first and second magnets, thus limiting their descent speed). On the one hand, the clamping block and the mold will not damage the base due to excessive descent speed; on the other hand, the clamping block and the mold will not generate excessive noise due to excessive descent speed.

[0012] As a further improvement to the above technical solution, a limiting block is provided on the support rod. This limiting block restricts the descent position of the clamping block, ensuring that the first magnet and the second magnet do not collide due to mutual contact, thereby preventing damage to the first magnet and the second magnet.

[0013] As a further improvement to the above technical solution: the distance between the upper surface of the limiting block and the upper surface of the base is d1, and the thickness of the first magnet and the thickness of the second magnet are both d2; wherein: d1 > 2*d2. Therefore, by using the design method of d1 > 2*d2, it is ensured that when the pressing block is limited by the limiting block, there is still a gap between the first magnet and the second magnet, and they will not come into contact.

[0014] As a further improvement to the above technical solution: Multiple fixing blocks are also provided on one side of the clamping block relative to the hydraulic demolding mechanism. The cross-sectional shape of the fixing blocks is arc-shaped, and each fixing block has a second locking member threaded through it. The second locking member is threadedly connected to the fixing block. Thus, through the cooperation of the fixing blocks and the second locking members, it is ensured that during demolding, the clamping block connects to the mold and moves downwards synchronously, ensuring that the mold will not continue to move downwards when the clamping block abuts against the limiting block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting multiple adjustment mechanisms, the positions of the molded sample and mold relative to the hydraulic lifting mechanism can be adjusted so that the axis of the molded sample, the axis of the mold, and the axis of the hydraulic lifting mechanism coincide. Compared with the existing method of directly placing the molded sample and mold on the hydraulic lifting platform without adjustment, this method has a simple structure and is easy to operate. During demolding, by adjusting the positions of the molded sample and mold relative to the hydraulic lifting mechanism, the molded sample can pass through the first through hole without being blocked by the demolding module. In this way, the hydraulic demolding machine can achieve stable demolding operation, thereby improving the demolding efficiency and demolding effect of the hydraulic demolding machine.

[0017] 2. In this invention, during demolding, the clamping block and the hydraulic lifting mechanism jointly fix the molded sample and mold to be demolded, ensuring that the molded sample and mold will not shake during the upward process (i.e., they will not move relative to the hydraulic lifting mechanism, and the axis of the molded sample and the axis of the mold will not deviate from the axis of the hydraulic lifting mechanism). In this way, it can be ensured that the molded sample can pass through the second through hole and the first through hole, thereby realizing the demolding operation of the molded sample; the step part is engaged with the mold, which can further limit the mold to further ensure that the molded sample and mold will not shake during the upward process.

[0018] 3. During demolding, the present invention can limit the descent speed of the clamping block and the mold by the cooperation of the first magnet and the second magnet (that is, the gravity of the clamping block and the mold interacts with the repulsive force of the first magnet and the second magnet, which can limit the descent speed of the clamping block and the mold). On the one hand, the clamping block and the mold will not damage the base due to excessive descent speed, and on the other hand, the clamping block and the mold will not generate excessive noise due to excessive descent speed.

[0019] 4. This utility model limits the descent position of the pressing block by a limiting block to ensure that the first magnet and the second magnet will not collide due to mutual contact, thereby avoiding damage to the first magnet and the second magnet; by using the design method of d1>2*d2, it is ensured that when the pressing block is limited by the limiting block, there is still a gap between the first magnet and the second magnet, and the pressing block will not come into contact with the second magnet.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0044] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] like Figures 1 to 10The diagram shows the preferred embodiment of this utility model. The hydraulic demolding device for stable demolding in this embodiment includes: a hydraulic demolding mechanism 1, a demolding module 2, and multiple adjustment mechanisms 3. The demolding module 2 is located above the hydraulic demolding mechanism 1 and has a first through hole 201. When the hydraulic demolding mechanism 1 and the demolding module 2 come into contact, the hydraulic demolding mechanism 1 and the demolding module 2 work together to demold the molded sample. The multiple adjustment mechanisms 3 are distributed in a ring at equal intervals outside the hydraulic demolding mechanism 1. Each adjustment mechanism 3 includes: a first driving member 301 and an adjustment block 302. The telescopic end of the first driving member 301 is connected to the adjustment block 302. The first driving member 301 is used to drive the adjustment block 302 to move closer to or further away from the hydraulic demolding mechanism 1 to adjust the position of the molded sample relative to the hydraulic demolding mechanism 1. The multiple adjustment mechanisms 3 work together on the mold to make the axis of the molded sample, the axis of the mold, and the axis of the hydraulic demolding mechanism 1 coincide. Therefore, by setting multiple adjustment mechanisms 3, the positions of the molded sample and the mold relative to the hydraulic lifting mechanism can be adjusted so that the axis of the molded sample, the axis of the mold, and the axis of the hydraulic lifting mechanism coincide. Compared with the existing method of directly placing the molded sample and the mold on the hydraulic lifting platform without adjustment, this method has a simple structure and is easy to operate. During demolding, by adjusting the positions of the molded sample and the mold relative to the hydraulic lifting mechanism, the molded sample can pass through the first through hole 201 without being blocked by the demolding module 2. In this way, the hydraulic demolding machine can achieve stable demolding operation, thereby improving the demolding efficiency and demolding effect of the hydraulic demolding machine.

[0047] In other words, the existing method of not adjusting the molded sample and mold relative to the hydraulic lifting mechanism will cause the molded sample and mold to shift relative to the hydraulic lifting mechanism. As a result, during demolding, the molded sample will get stuck on the demolding module 2 and will not pass through the first through hole 201, which will affect the demolding operation of the hydraulic demolding device. Before demolding, this application adjusts the position of the molded sample and mold relative to the hydraulic lifting mechanism through multiple adjustment mechanisms 3 so that the axis of the molded sample, the axis of the mold, and the axis of the hydraulic lifting mechanism are aligned, that is, the molded sample is aligned with the first through hole 201. In this way, it can ensure that the molded sample passes through the first through hole 201 without obstruction, so as to achieve stable demolding operation of the hydraulic demolding device.

[0048] It should be noted that: such as Figure 9 As shown, this is the state of the molded sample before demolding. The molded sample is embedded in the mold and cannot move relative to the mold; as... Figure 10 As shown, the state of the molded sample after demolding is such that, under the action of external force (i.e., the force applied by the hydraulic lifting module), the molded sample is placed outside the mold, which is the state of the molded sample after demolding.

[0049] For example, the first driving component 301 is a cylinder.

[0050] In this embodiment, the device further includes a clamping block 4, located between the hydraulic demolding mechanism 1 and the demolding module 2. The clamping block 4 has a second through hole 401 positioned opposite the first through hole 201, and a step portion 402 is provided on the side of the clamping block 4 closest to the hydraulic demolding mechanism 1. The axes of the first through hole 201, the second through hole 401, and the step portion 402 coincide. Therefore, during demolding, the clamping block 4 and the hydraulic lifting mechanism jointly fix the molded sample and mold to be demolded, ensuring that the molded sample and mold do not sway during the upward movement (i.e., they do not move relative to the hydraulic lifting mechanism, and the axes of the molded sample and mold do not deviate from the axis of the hydraulic lifting mechanism). This ensures that the molded sample can pass through the second through hole 401 and the first through hole 201, thereby achieving the demolding operation. The step portion 402 engages with the mold, further limiting the mold and ensuring that the molded sample and mold do not sway during the upward movement.

[0051] In this embodiment, it also includes: a base 5, a hydraulic demolding mechanism 1 connected to the base 5, a demolding module 2 connected to the base 5 via a support rod 6, a first driving member 301 connected to the base 5, and a clamping block 4 passing through the support rod 6 and slidably connected to the support rod 6.

[0052] In this embodiment, the hydraulic demolding mechanism 1 includes a second driving member 101 and a demolding seat 102. The second driving member 101 is connected to the base 5, and the demolding seat 102 is installed at the telescopic end of the second driving member 101. The demolding seat 102 is used to place the molded sample and the mold. Thus, the second driving member 101 can drive the demolding seat 102 to move up and down to realize the demolding operation of the molded sample.

[0053] For example, the second drive component 101 is a cylinder.

[0054] In this embodiment, when not demolded, the clamping block 4 is mounted on the demolding module 2 via the first locking member 202, and the clamping block 4 cannot move relative to the demolding module 2; when demolding, the first locking member 202 is in a loosened state, and the clamping block 4 can slide relative to the support rod 6. For example, the first locking member 202 is a bolt.

[0055] In this embodiment, a first magnet 403 is provided on the side of the clamping block 4 near the hydraulic demolding mechanism 1, and a second magnet 501 is provided on the side of the base 5 near the clamping block 4. The magnetism of the first magnet 403 and the second magnet 501 are repulsive. Thus, during demolding, the interaction between the first magnet 403 and the second magnet 501 can limit the descent speed of the clamping block 4 and the mold (i.e., the gravity of the clamping block 4 and the mold interacts with the repulsive force of the first magnet 403 and the second magnet 501, which can limit the descent speed of the clamping block 4 and the mold). On the one hand, the clamping block 4 and the mold will not damage the base 5 due to excessive descent speed; on the other hand, the clamping block 4 and the mold will not generate excessive noise due to excessive descent speed.

[0056] In this embodiment, a limiting block 601 is provided on the support rod 6; the distance between the upper surface of the limiting block 601 and the upper surface of the base 5 is d1, and the thicknesses of the first magnet 403 and the second magnet 501 are both d2; wherein: d1 > 2 * d2. Thus, the limiting block 601 limits the descent position of the pressing block 4 to ensure that the first magnet 403 and the second magnet 501 will not collide due to mutual contact, thereby avoiding damage to the first magnet and the second magnet 501; the design of d1 > 2 * d2 ensures that when the pressing block 4 is limited by the limiting block 601, there is still a gap between the first magnet 403 and the second magnet 501, and the first magnet 403 will not come into contact with the second magnet 501.

[0057] In this embodiment, a plurality of fixing blocks 404 are also provided on the side of the clamping block 4 opposite to the hydraulic demolding mechanism 1. The cross-sectional shape of the fixing blocks 404 is arc-shaped, and a second locking member 405 passes through each fixing block 404. The second locking member 405 is threadedly connected to the fixing block 404. Thus, through the mutual cooperation between the fixing blocks 404 and the second locking members 405, it is ensured that during demolding, the clamping block 4 is connected to the mold and moves downward synchronously, so as to ensure that when the clamping block 4 abuts against the limiting block 601, the mold will not continue to move downward.

[0058] For example, the second locking element 405 uses a bolt.

[0059] The demolding process of the molded sample of this utility model is as follows: First, the molded sample to be demolded and the mold are placed on the demolding base 102. At this time, the first driving component 301 is in a shortened state, and the clamping block 4 is fixed on the demolding module 2 by the first locking component 202. Next, the first driving component 301 is activated, which drives the adjusting block 302 to move closer to the mold. Through the combined action of multiple adjusting mechanisms 3, the axis of the molded sample, the axis of the mold, and the axis of the hydraulic lifting mechanism are aligned. Then, the first locking component 202 is loosened, so that the clamping block 4 moves downward and the step part 402 engages with the mold, and then it is tightened. The second locking member 405 is engaged with the mold. Then the first driving member 301 is activated to move the adjusting block 302 away from the mold. Finally, the second driving member 101 is activated to move the molded sample and the mold upward. After the clamping block 4 engages with the demolding seat 102, the mold is blocked from moving upward because it is engaged with the step part 402. The molded sample can pass through the second through hole 401 and the first through hole 201. In this way, the demolding operation of the molded sample can be realized. After the molded sample is demolded, the clamping block 4 and the mold move downward until the clamping block 4 engages with the limiting block 601.

[0060] In summary, this utility model, through the provision of multiple adjustment mechanisms 3, can adjust the position of the molded sample and the mold relative to the hydraulic lifting mechanism, so that the axis of the molded sample, the axis of the mold, and the axis of the hydraulic lifting mechanism coincide. Compared with the existing method of directly placing the molded sample and the mold on the hydraulic lifting platform without adjustment, this method has a simple structure and is easy to operate. During demolding, by adjusting the position of the molded sample and the mold relative to the hydraulic lifting mechanism, the molded sample can pass through the first through hole 201 without being blocked by the demolding module 2. In this way, stable demolding operation of the hydraulic demolding device can be achieved, thereby improving the demolding efficiency and demolding effect of the hydraulic demolding device.

[0061] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
