Description

Technical Field

[0001] This utility model belongs to the field of demolding technology, specifically relating to an electro-hydraulic inorganic material specimen demolding device. Background Technology

[0002] In fields such as materials mechanics, civil engineering, and materials research and development, it is often necessary to use molds to form specimens, and then use testing machines to test the performance of the specimens. During the testing process, it is often necessary to remove the formed specimen from the mold so that subsequent mechanical property tests or dimensional inspections can be carried out.

[0003] Hydraulic demolding machines are widely used in traditional demolding methods. These devices typically rely on hydraulic systems to apply force and eject the specimen from the mold. Hydraulic demolding machines offer high operational stability, but their high cost and complex maintenance limit their application in some small laboratories.

[0004] When using a hydraulic demolding machine for demolding, the specimen can only be demolded normally if the adhesion between the specimen and the mold wall does not exceed the rated power of the demolding machine. Once the adhesion exceeds the rated power of the machine, not only will the specimen not be able to be demolded, but the machine will also be damaged. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to design an electro-hydraulic inorganic material specimen demolding device to facilitate specimen demolding.

[0006] The specific technical solution of this utility model is as follows: An electro-hydraulic inorganic material specimen demolding device includes a support mechanism and a load application mechanism. The support mechanism includes a top plate, a middle plate, and a bottom plate fixed together by multiple columns. The top plate has an upper through hole, the middle plate has a central demolding hole, and the bottom plate is provided with a specimen protective sleeve. The load application mechanism includes a connecting base and a force-applying column fixed together, the force-applying column being able to pass through the upper through hole and the central demolding hole.

[0007] The specimen protective sleeve consists of two half-sleeves, one side of which is hinged together and the other side is connected together by a locking mechanism.

[0008] The connecting base is provided with connecting bolt holes.

[0009] Compared with the prior art, the technical effect of this utility model is that by combining the force application function of the universal testing machine with the precise demolding process, this utility model achieves a demolding operation with higher precision and lower cost.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-4 An electro-hydraulic inorganic material specimen demolding device includes a support mechanism 10 and a load application mechanism 20.

[0016] The support mechanism 10 includes a top plate 11, a middle plate 12, and a bottom plate 13 fixed together by multiple columns 14. The top plate 11 is provided with an upper plate through hole 111, the middle plate 12 is provided with a middle demolding hole 121, and the bottom plate 13 is provided with a specimen protective sleeve 30.

[0017] The load application mechanism 20 includes a connecting base 21 and a force application column 22 fixed together. The force application column 22 can pass through the upper plate through hole 111 and the middle demolding hole 121.

[0018] like Figure 1 To facilitate the removal of the specimen, the specimen protective sleeve 30 includes two half-sleeves, one side of which is hinged together and the other side is connected together by a locking element 32 (such as a bolt).

[0019] like Figure 3 To facilitate connection with the universal testing machine, the connecting base 21 is provided with connecting bolt holes 211.

[0020] The support mechanism 10 and the load application mechanism 20 are made of high-strength aluminum alloy, which reduces weight while maintaining rigidity.

[0021] Electro-hydraulic type: It adopts electric drive and hydraulic transmission technology. The hydraulic pump driven by the motor generates pressurized fluid to provide power support for the device and realize precise demolding operation.

[0022] Specimens: Mainly inorganic material specimens, non-metallic material samples formed by molding and curing, such as cement concrete, asphalt mixture, adobe, etc., are used for physical and mechanical property testing.

[0023] Demolding device: A mechanical device that uses a universal testing machine or other mechanical equipment to separate a molded and cured material specimen from its mold. Its working principle is as follows: S1. Connection: Place the support mechanism 10 within the force application range of the universal testing machine, and connect the connecting base 21 to the force application component of the universal testing machine. The connecting base 21 is connected and fixed to the universal testing machine using bolts.

[0024] S2. Place the specimen: Place the specimen (which is wrapped in a mold) on the upper surface of the middle plate 12, aligning the specimen with the middle demolding hole 121, with the mold located outside the middle demolding hole 121.

[0025] S3. Demolding: Start the universal testing machine and press down its force-applying components, causing the connecting base 21 and the force-applying column 22 to move downwards simultaneously. The force-applying column 22 passes through the upper plate through hole 111, the middle demolding hole 121, and then enters the mold, pushing the specimen downwards. At the same time, the middle plate 12 blocks the mold from moving downwards. In this way, the demolding operation is completed, and the specimen moves downwards and enters the protective sleeve 30.

[0026] S4. Remove the test piece: Unlock the locking piece 32, pry open the protective cover 30, and remove the test piece.

[0027] This utility model has the following significant advantages: S1. This utility model is a novel demolding machine that combines the advantages of a universal testing machine and a traditional hydraulic demolding machine. By designing a dedicated demolding frame, the force application function of the universal testing machine is combined with the precise demolding process, achieving higher precision and lower cost demolding operation.

[0028] S2. This demolding machine is designed with a structure that works in conjunction with a universal testing machine. It pushes the specimen to demold by applying precise force and displacement. It can demold normally when the adhesion force between the specimen and the protective wall does not exceed 1000KN.

[0029] S3. A receiving mold was designed to ensure that the specimen falls directly into the receiving area after demolding, avoiding damage caused by free fall. The design of the receiving mold ensures the integrity of the specimen after demolding and improves the protection of the specimen.

[0030] S4. Different sizes of intermediate demolding holes can be designed, and different sizes of molds can be demolded using different sized pads. The demolding machine designed in this way has high flexibility. By simply changing the corresponding position of the mold, it can demold specimens of different sizes and types, meeting diverse needs.

[0031] S5. Low cost: Compared with traditional hydraulic demolding machines, the demolding device in this design uses an existing universal testing machine to apply force. This device is low in cost, which greatly reduces equipment investment and maintenance costs.

[0032] S6. Specimen Protection: The bottom receiving mold ensures that the specimen can fall directly into the receiving area after it is removed, avoiding damage caused by free fall.

[0033] S7. High rated power: Normal demolding is possible when the adhesion force between the specimen and the protective wall does not exceed 1000KN. Among existing materials, this power can meet the requirements of all specimens.

[0034] S8. Easy to operate: The demolding machine in this design is combined with a universal testing machine, making it easy to operate without complicated procedures. Any trained staff can operate it easily, reducing the complexity of the operation.

[0035] For other details, please refer to the existing technology.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
