Description

Technical Field

[0001] This utility model relates to the field of ceramic blank processing technology, and more specifically, to a ceramic blank pressing and forming device. Background Technology

[0002] The pressing and molding of ceramic blanks is one of the key steps in the preparation of ceramic products. This process involves pressing powdered ceramic raw materials into ring-shaped blanks under certain pressure conditions.

[0003] Existing ceramic blank pressing devices involve manually placing ceramic raw materials into a mold and then pressing them with mechanical pressure to ensure the required density and shape, thus forming a ring-shaped ceramic blank. However, the manual feeding of ceramic raw materials into the mold reduces the processing efficiency of the ceramic blank. Furthermore, the formed ceramic blank is prone to getting stuck in the mold and is difficult to remove, making the operation quite laborious. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0045] See attached document Figure 1As shown, a ceramic blank pressing and forming apparatus includes:

[0046] A base frame 1 is set on the ground and a mounting bracket 11 is provided on it;

[0047] Raw material pipe 2 is vertically mounted on base frame 1;

[0048] The injection assembly 3 is connected to the side of the raw material tube 2 to inject the raw material into the raw material tube 2 in a metered manner;

[0049] The feeding assembly 4 is connected to the inside of the raw material pipe 2 to push out the raw material inside the raw material pipe 2;

[0050] The lower mold 5 of the annular groove is set at the top of the raw material pipe 2 to receive the raw material discharged from the raw material pipe 2;

[0051] The ejector assembly 6 is connected inside the lower mold 5 of the annular groove to eject the formed ceramic blank inside the lower mold 5 of the annular groove;

[0052] The pressing component 7 is mounted on the mounting bracket 11;

[0053] The upper annular mold 8 is connected to the pressing assembly 7 and is located directly above the lower annular mold 5 to press the raw material inside the lower annular mold 5.

[0054] In the specific implementation process of this utility model, ceramic powder raw material is quantitatively injected into raw material tube 2 through injection component 3. Then, feeding component 4 operates to push the raw material in raw material tube 2 into the lower mold 5 of the annular groove (then feeding component 4 resets). At this time, pressing component 7 operates to drive the upper annular mold 8 to move down and enter the lower annular groove mold 5 to realize the pressing and forming of the raw material in the lower annular groove mold (then pressing component 7 resets). Finally, ejecting component 6 operates to eject the formed ceramic blank in the annular groove (then ejecting component 6 resets). In this way, the pressing and forming operation of ceramic blank is realized once. Of course, this process can be repeated to realize several pressing and forming operations of ceramic blank.

[0055] For the above scheme, please refer to the appendix. Figure 1 and attached Figure 2 As shown, the injection assembly 3 includes:

[0056] Storage bin 31 contains ceramic powder raw materials;

[0057] The powder pump 32 has its inlet end connected to the outlet end of the storage tank 31;

[0058] One end of the injection pipe 33 is connected to the discharge end of the powder pump 32, and the other end is connected to the side of the raw material pipe 2.

[0059] During implementation, the powder pump 32 delivers a fixed amount of raw material each time by setting a fixed stroke or volume, thereby quantitatively delivering the ceramic powder raw material in the storage tank 31 to the raw material pipe 2 through the injection pipe 33.

[0060] Of course, for the injection component 3, in specific implementation, the existing pneumatic conveying system or screw feeder can also be used. This utility model will not elaborate further on this.

[0061] For the above scheme, please refer to the appendix. Figure 1 As shown, the feeding component 4 includes:

[0062] The feeding telescopic cylinder 41 is set on the base frame 1 and its telescopic end extends into the inside of the raw material pipe 2;

[0063] The feeding plate 42 is connected to the telescopic end of the feeding telescopic cylinder 41 and is slidably disposed inside the raw material pipe 2, and is initially positioned below the discharge port of the injection pipe 33.

[0064] During implementation, a raw material pre-storage cavity is formed between the feeding plate 42 and the discharge port of the injection pipe 33. When the raw material in the pre-storage cavity reaches the required amount, the feeding telescopic cylinder 41 operates to move the feeding plate 42 upward until the raw material is pushed out of the raw material pipe 2.

In the initial state, the top surface of the ejector rod 63 is flush with the bottom surface of the interior of the lower mold 5 of the annular groove.

[0069] During the process, when the ceramic blank is formed in the lower mold 5 of the annular groove, the operation of the ejector telescopic cylinder 61 causes the sliding sleeve 62 to move upward, and finally causes the ejector rod 63 to push upward along the inside of the lower mold 5 of the annular groove, thereby ejecting the ceramic blank from the lower mold 5 of the annular groove.

[0070] For the above scheme, please refer to the appendix. Figure 1 As shown, the compression component 7 includes:

[0071] The compression telescopic cylinder 71 is vertically mounted on the mounting frame 11;

[0073] The fixed frame 73 is connected to the pressing telescopic cylinder 71 and the guide rod 72, and the ring upper mold 8 is set on the fixed frame 73;

[0074] During the process, after the raw material is injected into the lower mold 5 of the annular groove, the pressing telescopic cylinder 71 operates to drive the fixed frame 73 to move down, so that the upper mold 8 of the annular groove is connected to the lower mold 5 of the annular groove to complete the pressing and forming operation. After the forming is completed, the pressing telescopic cylinder 71 is reset.

[0075] Furthermore, considering the automated operation of the device in the above scheme, please refer to the appendix. Figure 4 As shown, a ceramic blank pressing and forming device further includes:

[0076] The feeding component 9 is installed on the mounting bracket 11 and is set in correspondence with the lower mold 5 of the annular groove to feed the ceramic blank that is ejected above the lower mold 5 of the annular groove.

[0081] The feeding chute 94 is installed at an angle on the other side of the mounting frame 11, and the feeding end is connected to the lower mold 5 of the annular groove;

[0082] During the process, the pressed ceramic blank is ejected above the lower mold 5 of the annular groove. Then, the feeding telescopic cylinder 91 operates to drive the feeding plate 93 forward, and finally pushes the ceramic blank on the lower mold 5 of the annular groove to the feeding groove 94 for feeding.
