[0036] As shown in the attached Figure 1 - attached Figure 10 figure, the present utility model provides a die for molding an outer guide, including a bottom fixed die 3, a bottom movable die 4, a side wall outer die 2, a side wall inner die 6, a positioning ring 5, and a top die 8;

[0037] The side wall outer die 2 is sleeved on the outer wall of the bottom fixed die 3. Preferably, the side wall outer die 2 is detachably engaged with the bottom fixed die 3, that is, the side wall outer die 2 is slidably sleeved on the outer wall of the bottom fixed die 3. The positioning ring 5 is disposed in the middle of the bottom fixed die 3. Preferably, the positioning ring 5 is detachably arranged with the bottom fixed die 3, and the upper end of the positioning ring 5 protrudes from the bottom fixed die 3. The side wall inner die 6 is disposed on the bottom movable die 4. Preferably, the side wall inner die 6 and the bottom movable die 4 are detachably arranged. The bottom movable die 4 is slidably disposed on the positioning ring 5, that is, the bottom movable die 4 and the side wall inner die 6 can slide up and down together to mold the material.

[0038] The inner wall of the side wall outer mold 2, the outer wall of the side wall inner mold 6, the upper wall of the bottom fixed mold 3, the lower wall of the bottom movable mold 4, and a part of the outer wall of the positioning ring 5 enclose a to-be-formed cavity 9 with an open top. Among them, the to-be-formed cavity 9 includes a product side wall cavity and a product bottom wall cavity. The inner wall of the side wall outer mold 2 and the outer wall of the side wall inner mold 6 constitute the product side wall cavity, and the upper wall of the bottom fixed mold 3 and the lower wall of the bottom movable mold 4 constitute the product bottom wall cavity. The positioning ring 5 is located in the cavity between the upper wall of the bottom fixed mold 3 and the lower wall of the bottom movable mold 4 for closing the product bottom cavity;

[0039] The top mold 8 is placed on the upper end of the side wall inner mold 6. A downward pressure can be provided to the top mold 8 through a press device. The top mold 8 then pushes the side wall inner mold 6 downward, thereby molding the material in the product bottom wall cavity by pressing. And a forming pressing ring 81 is arranged on the top mold 8 and extends into the to-be-formed cavity 9 through the opening. When the press device provides a downward pressure to the top mold 8, the forming pressing ring 81 molds the material in the product side wall cavity by pressing. And at the same time, since the product side wall cavity and the product bottom wall cavity are connected, when the material in the product side wall cavity is molded by pressing, it will extrude the material in the product bottom wall cavity.

[0040] For the molding outer guiding forming mold of the present utility model, through the cooperation relationship among the top mold 8, the side wall inner mold 6, and the bottom movable mold 4, the side wall and the bottom wall of the product can be molded by pressing at one time. And the bottom wall of the product can be double-extruded by the bottom movable mold 4 and the material in the product side wall cavity, which can ensure the molding quality of the product bottom wall. The molding of the product bottom wall and the side wall is completed at one time, and the assembly, feeding, discharging, and disassembly processes of the whole mold are all convenient and fast, which can improve the molding efficiency. When performing carbon-carbon material molding, while ensuring the product strength, the matrix density of the green body is high, thereby shortening the densification process time, greatly shortening the molding cycle, and improving the utilization rate of the equipment.

[0041] In one embodiment, the molding outer guiding forming mold further includes a base 1. The bottom fixed mold 3 is detachably and fixedly arranged on the base 1. By setting the base 1, it is convenient to fix the bottom fixed mold 3 and the alignment effect between the bottom fixed mold 3 and the side wall outer mold 2. Preferably, the bottom fixed mold 3 is detachably fixed on the base 1 by bolts.

[0042] In one embodiment, a positioning groove 11 adapted to the bottom fixed mold 3 is arranged on the base 1. The bottom fixed mold 3 is embedded in the positioning groove 11 and can be fixed in the positioning groove 11 by gravity. The setting of the positioning groove 11 facilitates the quick and accurate positioning and installation of the bottom fixed mold 3 on the base 1, improving the installation efficiency and installation accuracy.

[0043] In one embodiment, an installation groove 31 for installing the positioning ring 5 is provided in the middle of the bottom fixed mold 3. The positioning ring 5 is embedded in the installation groove 31 and can be fixed in the installation groove 31 by gravity. The setting of the installation groove 31 facilitates the quick and accurate positioning and installation of the positioning ring 5 on the bottom fixed mold 3, improving the installation efficiency and accuracy.

[0044] Through holes 32 are provided on the installation groove 31, and disassembly holes 12 corresponding to the through holes 32 are provided on the base 1. When it is necessary to disassemble the positioning ring 5 from the bottom fixed mold 3, a tool can be operated to eject the positioning ring 5 through the disassembly holes 12 and the through holes 32, simplifying the disassembly difficulty.

[0045] In one embodiment, a pressure equalizing ring 7 is further provided between the top of the bottom moving mold 4 and the lower wall of the top mold 8. Preferably, one end of the pressure equalizing ring 7 is fixed on the bottom moving mold 4, and the other end is flush with the upper end of the side wall inner mold 6. When the top mold 8 provides a downward pressure, it simultaneously contacts the upper end of the side wall inner mold 6 and the upper end of the pressure equalizing ring 7, thereby balancing the downward pressures at different radial positions of the bottom moving mold 4, making the force on the bottom moving mold 4 balanced during the downward pressing and forming process, and ensuring the uniformity of the forming of the bottom wall of the product. It should be noted that before the top mold 8 is pressed downward, the upper ends of the side wall inner mold 6 and the pressure equalizing ring 7 are flush and higher than the side wall outer mold 2. At this time, the downward displacement of the top mold 8 will not squeeze the side wall outer mold 2. After the product is molded in place, the upper end of the side wall outer mold 2 can be flush with the upper ends of the side wall inner mold 6 and the pressure equalizing ring 7.

[0046] In one embodiment, a sliding hole 41 that slidably cooperates with the outer wall of the positioning ring 5 is provided on the bottom moving mold 4, that is, the bottom moving mold 4 is slidably arranged on the outer wall of the positioning ring 5 through the sliding hole 41, thereby realizing that the bottom moving mold 4 can only slide along the axial direction of the positioning ring 5 and avoiding the deviation of the bottom moving mold 4 in other directions.

[0047] An engaging step 42 for installing the pressure equalizing ring 7 is provided at the top of the sliding hole 41. The outer wall and the bottom wall of the pressure equalizing ring 7 are arranged on the engaging step 42, and the inner wall is slidably arranged on the outer wall of the positioning ring 5, thereby ensuring the installation stability and moving guiding property of the pressure equalizing ring 7.

[0048] In one embodiment, a ventilation hole 82 is provided on the top mold 8. The upper end of the positioning ring 5 is sleeved inside the pressure equalizing ring 7. The positioning ring 5 and the pressure equalizing ring 7 are tubular structures with a hollow interior and open ends at both ends, and the disassembly hole 12, the through hole 32, the positioning ring 5, the pressure equalizing ring 7, and the ventilation hole 82 are sequentially connected. At this time, when the mold together with the molded product is transferred to an oven for curing, heat can enter the inside of the mold through the ventilation hole 82 and the disassembly hole 12, improving the uniformity of product curing, and at the same time reducing the weight of the mold and lowering the cost.

[0049] In one embodiment, the outer walls of the base 1 and the top mold 8 both protrude beyond the side wall outer mold 2. Corresponding fitting grooves 10 are provided on the protruding parts of the outer walls of the base 1 and the top mold 8. Two corresponding fitting grooves 10 are used for connecting and fixing the fasteners of the base 1 and the top mold 8. The fasteners can be bolt assemblies. Preferably, multiple groups of fitting grooves 10 are provided on the outer walls of the base 1 and the top mold 8, thereby improving the fixing stability of the base 1 and the top mold 8. In this embodiment, after molding, the base 1 and the top mold 8 are fixed by fasteners, and then the overall mold forms a whole, which is convenient to be transferred into an oven for curing.

[0050] In one embodiment, a socket ring 43 is provided on the top of the bottom movable mold 4. The side wall inner mold 6 is sleeved on the outer wall of the socket ring 43. By providing the socket ring 43, the inner wall of the side wall inner mold 6 is sleeved on the socket ring 43, and the bottom wall abuts against the upper end surface of the bottom movable mold 4 to complete the fixation, which can improve the fixing stability and prevent the side wall inner mold 6 from axially shifting on the bottom movable mold 4. At the same time, the installation efficiency and installation accuracy are improved.

[0051] In one embodiment, draft angles are provided on the side wall outer mold 2 and the side wall inner mold 6 to facilitate the disassembly of the product.

[0052] The specific working process of this compression molding outer guide forming mold is as follows:

[0053] S1. Assemble the bottom fixed mold 3 onto the base 1 and lock it with multiple countersunk bolts to ensure that the bottom fixed mold 3 fits tightly with the base 1.

[0054] S2. Assemble the positioning ring 5 onto the bottom fixed mold 3.

[0055] S3. Weigh a certain amount of material and fill it onto the bottom fixed mold 3, and press the bottom movable mold 4 onto the material.

[0057] S5. Fill a certain amount of prepared material into the product side wall cavity, and assemble the top mold 8 into the cavity.

[0058] S6. Press down the top mold 8 through the press. The top mold 8 presses down the sidewall inner mold 6 and the pressure equalizing ring 7. The sidewall inner mold 6 and the pressure equalizing ring 7 press down the bottom moving mold 4. At the same time, the forming pressing ring 81 of the top mold 8 compacts the material in the product sidewall cavity. At the same time, the material in the product sidewall cavity compacts the material in the product bottom wall cavity, and pre-cures the compaction of the material in the product sidewall cavity and the product bottom wall cavity.

[0059] S7. After locking the top mold 8 and the base 1 through two sets of fitting grooves 10 with the screw, put them into the oven for curing.

[0060] S8. After curing, remove the bolts, then remove the top mold 8 and the pressure equalizing ring 7 in sequence and place them aside. Lift the sidewall outer mold 2 and then place it on the base 1 again to avoid damaging the product when removing the sidewall inner mold 6.
