Description

Technical Field

[0001] This utility model relates to the field of demolding equipment technology, specifically to a device for demolding high-temperature alloy master alloys. Background Technology

[0002] In the production process of casting high-temperature master alloys, the direct casting method of molten steel is often used. The molten master alloy steel in the crucible is poured into a predetermined mold, and after demolding, a high-temperature master alloy bar is obtained. During demolding, the commonly used method is to fix the mold and then eject the high-temperature master alloy bar using a cylinder or other power device.

[0003] For example, patent document CN222790609U discloses a pneumatic device for demolding high-temperature alloy master alloys, including a C-shaped frame and a cylinder, as well as a lifting mechanism and a positioning mechanism located on one side of the C-shaped frame. The lifting mechanism and positioning mechanism are respectively located at both ends of the C-shaped frame. The lifting mechanism includes a driving component, a threaded rod, and a placement plate. The driving component is located on the C-shaped frame, and the output shaft of the driving component passes through the C-shaped frame and connects to the threaded rod. The threaded rod is vertically arranged, and one end of the threaded rod is hinged to the C-shaped frame. The placement plate is horizontally placed and threadedly engaged with the threaded rod. When the threaded rod rotates, it drives the placement plate to move up and down. The cylinder is located on the placement plate. This device can fix rod molds of different lengths through the positioning mechanism and adjust the position of the demolding module through the lifting mechanism, thereby allowing the high-temperature alloy master alloy rod to detach smoothly from the rod mold. However, in the above technology, the alloy rod is detached from the rod mold solely by the thrust of the driving component, resulting in low working efficiency. Utility Model Content

[0023] During demolding, the mold is fixed by the fixing device 8, and the telescopic part 3 of the power element 2 acts on the bar to push it out. The vibration generated by the vibration generator 4 facilitates the separation of the bar from the mold.

[0024] In some embodiments, such as Figure 1 As shown, a push rod 9 is provided at the lower end of the vibration generator 4, and a push head 10 is provided at the lower end of the push rod 9.

[0025] It should be noted that the height of the frame 1 and the length of the push rod 9 can be adjusted as needed. In use, the frame 1 can also be placed horizontally as required.

[0026] In some embodiments, the vibrating body 14 has a rotating disk 142 coaxial with the central shaft portion 141 (as the rotation axis 145) and located at the midpoint of the length direction of the central shaft portion 141. The rotating disk 142 has a toothed portion 146 arranged radially outwardly around it. The toothed portion 146 is used to drive the vibrating body 14 to rotate around the rotation axis 145 under the action of a fluid (see...). Figure 5 (As indicated by the middle arrow).

[0027] In some embodiments, there are two counterweights, namely a first counterweight 143 and a second counterweight 144; the first counterweight 143 and the second counterweight 144 are symmetrically arranged on both sides of the rotating disk 142.
