Description

Technical Field

[0001] This utility model relates to the field of ceramic forming and processing technology, specifically to an internal propeller device for ceramic forming. Background Technology

[0002] Ceramic molding typically involves injecting slurry into a mold, shaping it, and then demolding it. While inside the mold, the slurry needs to be rotated at high speed to adhere to the mold's inner wall. Currently, the mold is placed directly on a rotary table for high-speed centrifugal motion, meaning the mold rotates along with the ceramic. This method has the following problems:

[0003] The mold needs to be moved to a rotary table, which is quite difficult for large molds.

[0004] The center of the mold needs to be aligned with the center of the turntable; otherwise, it is easy to deviate and fall off the turntable. If the mold is not at the center point of the turntable, the rotation will cause uneven slurry adhesion in the mold cavity and will affect the quality of ceramic product molding, resulting in problems such as suction, air holes, and inconsistent weight.

[0005] To address this issue, we propose an internal propeller device for ceramic forming, which solves the problems mentioned above. Summary of the Invention

[0006] The technical problem solved by this utility model is to provide an internal propeller device for ceramic forming.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an internal propeller device for ceramic forming, comprising a vertical plate and a propeller mechanism, wherein a slide rail is installed on the surface of the plate, a slider slides on the slide rail, the propeller mechanism is connected to the slider, a drive source is installed on the top of the plate, the drive end of the drive source is connected to the propeller mechanism, and the drive source drives the propeller mechanism to move up and down on the surface of the plate;

[0008] The propeller mechanism includes an L-shaped support plate, which is fixed to a slider. A vertical drive rod is installed on the lower end face of the L-shaped support plate, and a blade is connected to the bottom of the drive rod. A motor is installed on the upper end face of the L-shaped support plate, and the drive end of the motor is connected to the top of the drive rod.

[0009] Furthermore, the drive source is one of a cylinder, a lead screw, or a hydraulic rod.

[0010] Furthermore, the blades are connected to the drive rod via a pivot pin.

[0011] Furthermore, the bottom of the drive rod has a notch, one end of the blade is inside the notch, both ends of the notch are open, and one end of the notch has a protrusion.

[0012] Furthermore, the blade tips of the propeller blades are curved upwards.

[0013] The beneficial effects of this utility model are as follows: The propeller mechanism in this utility model can be placed above the mold. Under the action of power, the propeller blades of the propeller mechanism enter the mold cavity and rotate the slurry in the cavity at high speed, which plays the role of centrifugal propeller. The mold does not need to rotate with it, which can effectively solve the problems mentioned in the background section. Moreover, the propeller blades are installed movably. When the propeller motor stops, the propeller blades will close due to gravity. The closed state reduces the resistance when the propeller blades enter the slurry. When leaving the slurry, it can prevent the slurry from adhering to the propeller blades and detaching from the mold. At the same time, it improves the pass rate of ceramic product molding. The molded ceramic products are free of suction, air holes, and have a consistent weight. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-2 As shown, the present invention discloses an internal propeller device for ceramic forming, comprising a vertical plate 2, which can be supported by a support member. The propeller is located directly above the mold 1. A slide rail 3 is installed on the surface of the plate 2, and a slider 4 slides on the slide rail 3. The propeller mechanism is connected to the slider 4. A drive source 5 is installed on the top of the plate 2, and the drive end of the drive source 5 is connected to the propeller mechanism. The drive source 5 pushes the propeller mechanism to move up and down on the surface of the plate 2.

[0020] When the propeller mechanism descends, the blade 9 enters the cavity of the mold 1, and the motor 8 is started. The motor 8 drives the drive rod 7 and the blade 9 to rotate, so the slurry in the mold 1 rotates rapidly. When it rises, the blade 9 disengages from the mold 1.

[0021] The propeller mechanism can be placed above the mold 1. Under the action of power, the propeller blade 9 of the propeller mechanism enters the cavity of the mold 1. The high-speed rotating propeller blade 9 drives the slurry in the cavity to centrifuge and spin. The slurry is thrown onto the mold cavity wall, while the mold 1 does not need to rotate. In this way, it is not necessary to move the mold 1 to the rotating table. One of this device can be equipped next to each mold 1 in advance.

[0022] The drive source 5 is one of the following: cylinder, lead screw, or hydraulic rod. All three components are existing technologies and are configured according to actual needs.

[0023] The blade 9 is connected to the drive rod 7 via the shaft pin 10. When the motor 8 is stopped, the blade 9 will close due to gravity, meaning that the blade 9 will enter the slurry vertically. The closed state reduces the resistance when the blade enters the slurry. Similarly, when leaving the slurry, it can prevent the slurry from adhering to the blade 9 and detaching it from the mold. Once the motor 8 is started, the blade 9 will open due to centrifugal force. When the blade 9 opens, it will drive the slurry to rotate together, thus performing the centrifugal swirling function.

[0024] The drive rod 7 has a notch at the bottom, and one end of the blade 9 is inside the notch. The two ends of the notch are open. One end of the notch has a protrusion 11, which can limit each blade 9 to rotate 90° in only one direction. In addition, the blade tip of the blade 9 is raised. During propulsion, the arched surface of the blade tip of the blade 9 is opposite to the slurry, increasing the contact area with the slurry and providing better propulsion for the slurry.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
