Abstract
Description
Technical Field
[0001] This application relates to the field of ceramic impeller production technology, and in particular to a ceramic impeller filter press forming device. Background Technology
[0002] A related technology (publication number: CN220922767U) discloses a pressure filter molding apparatus for producing ceramic impellers, including a sliding bottom mold and a top mold for pressure filter molding of ceramic impellers. After the sliding bottom mold and the top mold are closed, they form a cavity inside that facilitates the molding of the ceramic impeller. The sliding bottom mold includes a bottom mold base, above which is a circular cavity for disc molding of the ceramic impeller, and multiple filter holes are arranged in a ring array on the inner wall of the cavity.
[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies:
[0004] This ceramic impeller production filter press molding device, during the filter press process, is subjected to strong extrusion from the sliding bottom mold and the top mold, allowing excess binder to flow out from the filter holes. This effectively avoids situations where there is too much binder that cannot solidify or where the solidified disc requires further processing. However, after pressing, it cannot automatically demold, making it difficult to remove from the sliding bottom mold.
[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0018] The ceramic impeller filter press forming device disclosed herein includes a support frame, a first hydraulic actuator, a lifting plate, a mold, a first cylinder, a second cylinder, a second hydraulic actuator, a circular plate, and a first annular plate. The support frame includes a first support plate, a second support plate, and a third support plate that are parallel to each other in their respective planes. Along the height direction of the support frame, the first, second, and third support plates are distributed sequentially from bottom to top, and each support plate is used to support and install relevant components of the device. The second support plate includes a first through hole located at its center, which allows relevant components of the device to pass through. The first hydraulic actuator is mounted on the third support plate along the height direction of the support frame, with its moving end facing the first support plate, providing driving force to achieve linear movement. The lifting plate is mounted on the moving end of the first hydraulic actuator and moves up and down under the drive of the first hydraulic actuator.

Under the drive of the first hydraulic actuator, the mold can move into the interior of the second cylinder, and under the drive of the second hydraulic actuator, the circular plate can move to the exterior of the second cylinder.
[0019] In operation, controlling the first hydraulic actuator moves the lifting plate, which in turn moves the mold, ultimately pressing the ceramic powder and adhesive placed inside the second cylinder and located on the circular plate. During the pressing process, excess adhesive can flow out through multiple second through holes, thus avoiding problems such as excessive adhesive failing to solidify or poor molding results after solidification. Furthermore, the first annular plate and the first cylinder act as barriers to prevent splashing of the adhesive. After the mold resets, controlling the second hydraulic actuator moves the circular plate, thereby ejecting the pressed-molded part located inside the second cylinder. This enables automatic demolding, facilitating the removal of the pressed-molded part.

The support frame 10 includes a first support plate 11, a second support plate 12, and a third support plate 13 that are parallel to each other in their respective planes. Along the height direction of the support frame 10, the first support plate 11, the second support plate 12, and the third support plate 13 are distributed sequentially from bottom to top, and are used to support and install relevant components of the apparatus. The second support plate 12 includes a first through hole located at its center, which is used for the passage of relevant components of the apparatus. The first hydraulic actuator 20 is mounted on the third support plate 13 along the height direction of the support frame 10, with the moving end of the first hydraulic actuator 20 facing the first support plate 11, and is used to provide driving force to achieve linear movement. A lifting plate 30 is mounted on the moving end of the first hydraulic actuator 20 and moves up and down under the drive of the first hydraulic actuator 20. A mold 40 is mounted on the bottom surface of the lifting plate 30 and is used to press the mixture of ceramic powder and adhesive. A first cylinder 50 is mounted on the top surface of the second support plate 12 and surrounds the first through hole. A second cylinder 60 is mounted on the top surface of the first support plate 11, passes through the first through hole, and is coaxially distributed with the first cylinder 50. The first cylinder 50 and the second cylinder 60 together form a double-layer cylindrical structure. The second cylinder 60 includes a plurality of second through holes located at its top end for passing excess adhesive. A second hydraulic actuator 70 is mounted on the top surface of the first support plate 11 along the height direction of the support frame 10 and is located inside the second cylinder 60. The moving end of the second hydraulic actuator 70 faces the third support plate 13 and is used to provide driving force to achieve linear movement. A circular plate 80 is mounted on the moving end of the second hydraulic actuator 70, fitting against the inner wall of the second cylinder 60, and positioned below the plurality of second through holes along the height direction of the support frame 10. During pressing, the circular plate 80 supports the mixture. After pressing, the circular plate 80 ejects the molded part. Specifically, under the drive of the first hydraulic actuator 20, the mold 40 can move into the interior of the second cylinder 60, and under the drive of the second hydraulic actuator 70, the circular plate 80 can move to the exterior of the second cylinder 60.
[0039] The ceramic impeller filter press molding apparatus provided in this embodiment controls the operation of the first hydraulic actuator 20, which in turn moves the lifting plate 30. This, in turn, moves the mold 40, ultimately pressing the ceramic powder and adhesive placed inside the second cylinder 60 and located on the circular plate 80. During the pressing process, excess adhesive can flow out from multiple second through holes, thus avoiding the problem of excessive adhesive failing to solidify or poor molding effect after solidification. Furthermore, the first annular plate 90 and the first cylinder 50 can act as a barrier to prevent splashing of the adhesive. After the mold 40 is reset, controlling the operation of the second hydraulic actuator 70 moves the circular plate 80, thereby ejecting the pressed molding component located inside the second cylinder 60. This allows for automatic demolding, facilitating the removal of the pressed molding component.
