Description

Technical Field

[0001] The utility model relates to the technical field of demoulding equipment, in particular to an electric hydraulic demoulding device. Background Art

[0002] Electro-hydraulic demolding devices are widely used in the fields of construction, engineering, and materials testing, particularly in the molding and testing of materials such as concrete, asphalt, and alloy ingots. They utilize an electrically driven hydraulic system to eject molded parts from the mold. This device converts electrical energy into hydraulic energy, which is then used to push a plunger to release the molded part. However, existing electro-hydraulic demolding devices cannot accurately position the molded part before demolding, resulting in unsuccessful demolding and increased overall test piece processing time. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an electric hydraulic demoulding device capable of accurately positioning a test piece.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] An electric hydraulic demoulding device includes a box, a bracket, a hydraulic cylinder, a controller, a support plate, a top plate, and a positioning part; the top plate is fixedly connected to the bracket; the support plate is fixedly connected to the lower part of the bracket; the upper end of the support plate is symmetrically and detachably connected to two horizontally placed positioning parts; the output end of the hydraulic cylinder is clamped with a pad.

[0006] Furthermore, the positioning portion includes a telescopic motor and an arc plate; the telescopic motor is connected to the upper end of the support plate through bolts; and the arc plate is detachably connected to the output end of the telescopic motor.

[0007] Furthermore, a rubber pad is attached to the concave surface of the arc plate.

[0008] Furthermore, the concave surfaces of the arc plates on the two positioning portions are arranged opposite to each other.

[0009] Furthermore, a compacting cylinder is detachably connected to the upper end of the top plate.

[0010] Furthermore, the compaction cylinder includes a cylinder body and a fixed cover; the fixed cover is detachably connected to the upper end of the cylinder body and forms an annular groove.

[0011] Furthermore, the width of the annular groove is greater than the thickness of the top plate.

[0012] Furthermore, a placement box is fixedly connected to the side wall of the box body.

[0013] Furthermore, the controller is electrically connected to the hydraulic cylinder and the positioning part respectively.

[0014] Beneficial effects of the utility model:

[0015] The controller controls the supporting plates on the two positioning parts to move toward each other, so that the specimen can move relative to the pad and be located in the center of the pad, effectively ensuring the demoulding accuracy. At this time, the controller controls the hydraulic cylinder to work and eject the specimen in the specimen; when demoulding small-sized specimens, the compaction cylinder can be detachably installed on the top plate first. Since the fixed cover can fix the cylinder to the top plate, the staff does not need to use hand support until the specimen contacts the compaction cylinder, which ensures the accuracy of small-sized specimens when demoulding.

[0023] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features described below in the various embodiments of the present invention may be combined with one another as long as they do not conflict with one another.

[0024] Reference Figure 1-4 As shown, an electric hydraulic demoulding device includes a box body 1, a bracket 2, a hydraulic cylinder 3, a controller 4, and also includes a support plate 5, a top plate 6, and a positioning part 7; the top plate 6 is fixedly connected to the upper part of the bracket 2; the support plate 5 is fixedly connected to the lower part of the bracket 2; the upper end of the support plate 5 is symmetrically and detachably connected to two horizontally placed positioning parts 7; the output end of the hydraulic cylinder 3 is clamped with a pad 8.

[0025] It should be noted that the box body 1 can place most of the bracket 2 and the hydraulic cylinder 3 inside the box body to ensure the stability of the bracket 2 and the hydraulic cylinder 3; the hydraulic cylinder 3 is an ejection device that can cooperate with the pad 8 to eject the sample in the specimen, and is a key component for demolding; the controller 4 can control the operation of related components, and it is an existing technology, and technical personnel in this field can easily select it according to their own needs; the support plate 5 can place the specimen, and the top plate 6 plays the role of limiting the upper end of the specimen; the positioning part 7 can accurately position the specimen after it is placed on the support plate 5 to ensure the accuracy of the specimen demolding.

[0026] Specifically, the positioning unit 7 includes a telescopic motor 71 and an arc plate 72. The telescopic motor 71 is bolted to the upper end of the support plate 5. The arc plate 72 is detachably connected to the output end of the telescopic motor 71. The telescopic motor 71 cooperates with the arc plate 72 to move the specimen to the correct position for demolding.

[0027] Specifically, in order to ensure the stability of the test piece, a rubber pad 73 is attached to the concave surface of the arc plate 72 .

[0028] Specifically, in order to facilitate the contact between the test piece and the arc plate 72 , the concave surfaces of the arc plate 72 located on the two positioning parts 7 are arranged opposite to each other.

[0029] Specifically, in order to facilitate demoulding of small test pieces, a compacting cylinder 9 is detachably connected to the upper end of the top plate 6 .

[0030] Specifically, the compaction cylinder 9 comprises a cylinder body 91 and a fixed cover 92. The fixed cover 92 is detachably connected to the upper end of the cylinder body 91 and forms an annular groove 93. The cylinder body 91 can provide good support for small specimens. The fixed cover 92 can secure the cylinder body 91 to the top plate 6, eliminating the need for workers to manually support the specimen until it contacts the compaction cylinder 9.

[0031] Specifically, in order to ensure that the cylinder 91 and the fixed cover 92 can be tightened when threadedly connected, the width of the annular groove 93 is greater than the thickness of the top plate 6 .

[0032] Specifically, in order to facilitate the placement of components such as the compacting cylinder 9 , a placement box 10 is fixedly connected to the side wall of the box body 1 .

[0033] Specifically, the controller 4 is electrically connected to the hydraulic cylinder 3 and the positioning part 7 respectively, and each component can be effectively controlled by the controller 4.

[0034] The working principle of this utility model:

[0035] The specimen to be demoulded is placed on the pad 8 engaged with the hydraulic cylinder 3, and then the controller 4 controls the support plates 5 on the two positioning parts 7 to move toward each other, so that the specimen can move relatively on the pad 8 and be located in the center of the pad 8, effectively ensuring the demoulding accuracy. At this time, the controller controls the hydraulic cylinder 3 to work and eject the sample in the specimen; when demoulding small-sized specimens, the compaction cylinder 9 can be detachably installed on the top plate 6 first. Since the fixed cover 92 can fix the cylinder body 91 to the top plate 6, there is no need for the staff to hold it by hand until the specimen contacts the compaction cylinder 9, thereby ensuring the accuracy of small-sized specimens when demoulding.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
