Detailed implementation manners

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will describe the technical solutions of the present invention in detail. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present invention.

[0033] Refer to Figures 1-3 , the specific embodiment of the present invention provides a ceramic fiber tube shell forming mold, including:

[0034] The upper die base 1, and the upper die base 1 is fixedly connected to the downward pressing device;

[0035] The first upper half die 4 and the second upper half die 6, the first upper half die 4 and the second upper half die 6 are rotatably connected below the upper die base 1, and the first upper half die 4 and the second upper half die 6 form an upper die with a semi-circular cross-section;

[0036] The lower die 5, the lower die 5 is installed in the forming pool and is correspondingly arranged below the upper die;

[0037] The driving assembly, the driving assembly is installed at the bottom of the upper die base 1, and the first upper half die 4 and the second upper half die 6 are respectively driven by the driving assembly.

[0038] The existing ceramic fiber tube shell is formed by a semi-tube molding method, that is, it is formed by two sets of semi-tube molds. However, the semi-tube molds have defects. During the molding process, the edges of the product (ceramic fiber tube shell) will crack, affecting the quality of the product. In this application, a set of existing semi-tube molds is divided into a first upper half mold 4 and a second upper half mold 6. The combined first upper half mold 4 and second upper half mold 6 form a semi-circular upper mold, and the upper mold covers above the lower mold 5. The main function of the driving component is to drive the first upper half mold 4 and the second upper half mold 6 to rotate synchronously. When closing the mold, it drives the first upper half mold 4 and the second upper half mold 6 to swing towards the direction close to the lower mold 5 to form a clamping effect. After the mold closing is completed, vacuum is pumped between the upper mold and the lower mold 5 to filter the product between the upper mold and the lower mold 5 in the molding pool; through the clamping and filtering of the product, the phenomenon of edge cracking can be avoided, effectively improving the quality of the product.

[0039] Among them, the downward pressing device can be a pneumatic cylinder, and the pneumatic cylinder is installed on the workbench to realize the vertical lifting or lowering of the upper mold base 1, so as to drive the upper mold into the molding pool; a number of holes are respectively opened on the inner side walls of the first upper half mold 4 and the second upper half mold 6 and on the outer surface of the lower mold 5. For example, the dry holes are communicated with the negative pressure device to facilitate suction filtration. The negative pressure device is a conventional vacuum pumping device and will not be elaborated here.

[0040] A further optimized solution also includes:

[0041] Installation side plates 3, and two groups of installation side plates 3 are symmetrically and fixedly connected to both sides of the bottom of the upper mold base 1. The first upper half mold 4 and the second upper half mold 6 are coaxially rotatably connected between the two groups of installation side plates 3.

[0042] Such a setting facilitates the complete transfer of the first upper half mold 4 and the second upper half mold 6 into the molding pool to close the mold with the lower mold 5.

[0043] A further optimized solution also includes:

[0044] First connecting plates 9, and two groups of first connecting plates 9 are fixedly connected to both ends of the first upper half mold 4;

[0045] Second connecting plates 10, and two groups of second connecting plates 10 are fixedly connected to both ends of the second upper half mold 6. The first connecting plates 9 and the second connecting plates 10 are coaxially rotatably connected.

[0046] As Figure 2 shown, the two groups of second connecting plates 10 are located between the two groups of first connecting plates 9, or they can be staggered (not shown in the figure).

[0049] The axis of the rotating shaft 8 is located in the middle of the upper mold, that is, between the first upper half mold 4 and the second upper half mold 6. Avoidance areas 13 are respectively arranged on the outer sides of the rotation points of the first upper half mold 4 and the second upper half mold 6 to ensure synchronous rotation, opening or clamping between the first upper half mold 4 and the second upper half mold 6.

[0050] For a further optimized solution, the drive assembly includes:

[0051] The first hydraulic cylinder 2, the fixed end of the first hydraulic cylinder 2 is vertically fixedly connected to the bottom surface of the upper mold base 1, and the telescopic end of the first hydraulic cylinder 2 is installed on the top of the first upper half mold 4;

[0052] The second hydraulic cylinder 7, the fixed end of the second hydraulic cylinder 7 is vertically fixedly connected to the bottom surface of the upper mold base 1, and the telescopic end of the second hydraulic cylinder 7 is installed on the top of the second upper half mold 6;

[0053] The first connecting rod 11, the first connecting rod 11 is hinged between the telescopic end of the first hydraulic cylinder 2 and the first upper half mold 4;

[0054] The second connecting rod 12, the second connecting rod 12 is hinged between the telescopic end of the second hydraulic cylinder 7 and the second upper half mold 6.

[0055] Start the first hydraulic cylinder 2 and the second hydraulic cylinder 7 and shorten them, drive the first upper half mold 4 and the second upper half mold 6 to rotate a certain angle through the first connecting rod 11 and the second connecting rod 12; when the first upper half mold 4 and the second upper half mold are in the forming pool and above the lower mold 5, start the first hydraulic cylinder 2 and the second hydraulic cylinder 7 and extend them to clamp the product between the lower mold 5 and the upper mold (the first upper half mold 4 and the second upper half mold), and then start suction filtration; the edge quality of the product after demolding is effectively improved.

[0056] For a further optimized solution, the end of the first connecting rod 11 away from the first hydraulic cylinder 2 is inclined towards the first upper half mold 4, and the end of the second connecting rod 12 away from the second hydraulic cylinder 7 is inclined towards the second upper half mold 6.

[0057] With such a setting, it can ensure that the first hydraulic cylinder 2 smoothly drives the first upper half mold 4

[0058] For a further optimized solution, the sides of the first upper half mold 4 and the second upper half mold 6 away from the rotating shaft 8 respectively move radially 5 mm - 10 mm through the drive assembly.

[0059] The maximum sum of the swing amounts of the sides of the first upper half mold 4 and the second upper half mold 6 away from the rotating shaft 8 is 20 mm.

[0060] For a further optimized solution, the cross-section of the lower mold 5 is semi-circular. When the upper mold and the lower mold 5 are in the closed mold state, the lower mold 5 is correspondingly located inside the bottom of the upper mold, and the product is located between the upper mold and the lower mold 5.
