DETAILED DESCRIPTION

[0032] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0034] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] According to one embodiment of the present disclosure, Figure 1-5 As shown, the utility model provides a friction plate forming die, comprising:

[0038] A lower mold frame 5, wherein a receiving cavity 9 for receiving the material is formed in the lower mold frame 5, and the lower mold frame 5 is configured to be heated so as to heat the material in the receiving cavity 9;

[0039] The upper mold core 6 is disposed above the accommodating cavity 9. The upper mold core 6 is configured to be heated and to be able to move vertically up and down in the accommodating cavity 9;

[0040] The lower mold core 3 is disposed below the accommodating cavity 9, and the lower mold core 3 is configured to be able to move linearly up and down along the vertical direction in the accommodating cavity 9;

[0041] The first driving mechanism 10 is provided with a plurality of them, which are respectively arranged on both sides of the accommodating chamber 9. The first driving mechanism 10 has a retractable piston rod 11, and the piston rod 11 is connected to the slider core 12. The slider core 12 is configured to be driven by the piston rod 11 and can move back and forth in a horizontal direction in the accommodating chamber 9.

[0042] In this embodiment, a receiving cavity 9 is formed in the lower mold frame 5. The receiving cavity 9 is a hollow structure with openings at both ends. The receiving cavity 9 is arranged along the length direction of the lower mold frame 5. The upper mold core 6 is arranged above the receiving cavity 9. The upper mold core 6 includes an upper mold core body and a convex portion 13 formed in one piece. The convex portion 13 extends toward the lower mold frame 5. The shape of the convex portion 13 is adapted to the opening shape of the receiving cavity 9. The upper mold core 6 is configured to be able to move linearly up and down along the vertical direction, so that the convex portion 13 can move linearly up and down along the vertical direction in the receiving cavity 9.

[0043] The lower mold core 3 is arranged below the accommodating cavity 9, and the lower mold core 3 can move linearly up and down along the vertical direction in the accommodating cavity 9. In order to obtain the pressed friction plate, when the upper mold core 6 and the lower mold core 3 press the material in the accommodating cavity 9, the cross-sectional shape formed by the end surface of the convex portion 13 of the upper mold core 6, the end surface of the lower mold core 3 and the wall surface of the accommodating cavity 9 is constructed to be compatible with the cross-sectional shape of the pressed product, such as Figure 2 shown.

[0044] The above materials include the friction plate iron (i.e., substrate) and the required powder, which ultimately plays the role of friction of the friction plate. When using the mold of the present application to make a product, the substrate is first placed in the accommodating cavity one by one along the length direction of the accommodating cavity, and a certain amount of powder is placed between each substrate, and then the powder is solidified on the substrate by pressing and heating to form the product. Then, the product is taken out of the accommodating cavity, and each substrate constituting the product is separated to obtain a plurality of friction plate finished products, which improves production efficiency while maintaining the quality stability between the friction plates.

[0045] The friction plate forming mold of the present application is provided with a lower mold frame 5, which can accommodate materials, and the lower mold frame 5 and the upper mold core 6 can be heated, and the temperature of the material during heating can be accurately controlled. Therefore, when the material is pressed and formed by the mold, the quality of the pressed and formed product is good through accurate temperature control. In addition, the present application arranges the material in the accommodating cavity 9, and the upper mold core 6, the lower mold core 3 and the slider core press the material, so that multiple friction plate finished products can be obtained at the same time, with high production efficiency, and can ensure that the friction plates are at the same quality standard.

[0046] For example, in order to better compress the material and prevent the material (especially powder) from falling from the accommodating cavity, the width of the free end of the lower mold core 3 should be roughly the same as the width of the accommodating cavity, and the width of the free end of the lower mold core 3 is slightly larger than the width of its main body, so that the lower mold core 3 can move up and down more conveniently in the avoidance hole 14 of the lower mold plate 4, and prevent the lower mold core 3 from interfering with the avoidance hole 14 and hindering the movement of the lower mold core. Therefore, when the free end of the lower mold core 3 extends into the accommodating cavity 9 of the lower mold frame 5, the side wall surface of the free end of the lower mold core 3 contacts the wall surface of the accommodating cavity 9, and the two form a sealing surface, thereby preventing the material from falling from the accommodating cavity 9.

[0047] Furthermore, the width of the end of the convex portion 13 of the upper mold core 6 is also substantially the same as the width of the accommodating cavity 9, so that when the convex portion 13 of the lower mold core 3 extends into the accommodating cavity 9, the end side surface of the convex portion 13 contacts the wall surface of the accommodating cavity 9, and the two form a sealing surface, so that the material is pressed between the end surface of the convex portion of the upper mold core and the free end surface of the lower mold core.

[0048] For example, in this embodiment, in order to support the lower mold frame 5, the friction plate forming mold of the present application also includes a heatable lower mold plate 4, which is arranged below the lower mold frame 5 and the two are fixedly connected; the lower mold plate 4 is provided with an avoidance hole 14 for the lower mold core 3 to move linearly through, and the avoidance hole 14 is arranged corresponding to the accommodating cavity 9. The lower mold plate 4 and the lower mold frame 5 can be connected and fixed by fixing parts such as screws, pins, and screws. The avoidance hole 14 provided on the lower mold plate 4 is used to avoid the movement of the lower mold core 3, so that when the lower mold core 3 presses the material in the accommodating cavity 9, the lower mold core 3 passes through the avoidance hole 14 and extends into the accommodating cavity 9.

[0049] The lower mold plate 4 is configured to be heatable, specifically, in the same way as the heating method of the lower mold frame and the upper mold core. A third medium circulation channel 15 is formed in the lower mold plate 4, and the third medium circulation channel 15 is used to circulate the heated medium to heat the lower mold plate 4. The third medium circulation channel 15 is sealed and connected to the external heat-conducting medium through a third joint 16 provided on the side of the lower mold plate 4. This ensures that the material in the accommodating cavity 9 is heated in all directions, ensures that the material is heated evenly, and through the precise temperature control of the lower mold plate 4, the lower mold frame 5 and the upper mold core 6, the quality of the pressed product remains stable, so that the quality of the friction plate finally obtained is maintained at the same level. Among them, the medium can be heat-conducting oil.

[0050] For example, the first driving mechanism 10 is installed on the side of the lower mold plate 4 through the mounting plate 17. The first driving mechanism 10 realizes the linear movement of the slider core 12 through the slider guide rail assembly. The specific slider guide rail assembly includes a slider seat 18 and a guide rail 19. The guide rail 19 is installed on the lower mold plate 4. The slider seat 18 is slidably installed on the guide rail 19 and can move back and forth linearly along the guide rail 19. The piston rod 11 of the first driving mechanism 20 is connected to the slider core 12 through the slider seat 18. The movement of the piston rod 11 synchronously drives the slider seat 18 to move back and forth linearly on the guide rail 19, thereby synchronously driving the slider core 12 to move back and forth linearly in the horizontal direction in the accommodating cavity 9. Among them, the left and right sides of the lower mold frame 5 are respectively provided with openings 20 at the corresponding slider core positions, and the openings 20 are connected to the accommodating cavity 9. The end of the piston rod 11 is fixedly connected to the slider seat 18, one end of the slider core 12 is inserted into the slider seat and fixed in the slider seat 18, and the other end of the slider core 12 is movably arranged in the opening 20 of the lower mold frame. The slider core 12 can be driven by the first driving mechanism 10 to move back and forth in a horizontal direction in the accommodating cavity 9. The cross-sectional shape of the slider core 12 is adapted to the required cross-sectional shape of the product.

[0051] In one embodiment, a plurality of first medium circulation channels 21 that do not interfere with each other are formed in the upper mold core 6. The first medium circulation channels 21 are used to circulate the heating medium to heat the upper mold core 6. The first medium circulation channels 21 are sealed and connected to the first joint 22 provided on the side of the upper mold core. The first joint 22 is used to be sealed and connected to the external heat-conducting medium, so that the heat-conducting medium flows into the first medium circulation channels 21 of the upper mold core 6 through the first joint 22, thereby heating the upper mold core 6. For example, the medium can be heat-conducting oil. The oil temperature is used to achieve precise temperature control of the upper mold core 6, and the upper mold core 6 is heated more evenly, thereby improving the quality of the pressed molded product and making the product quality more stable.

[0052] A second medium circulation channel 23 is formed in the lower mold frame 5, and the second medium circulation channel 23 is used to circulate the heated medium to heat the lower mold frame 5. Specifically, a plurality of second medium circulation channels 23 are provided and do not interfere with each other. The second medium circulation channel 23 is sealed and connected with a second joint 24 provided on the side of the lower mold frame 5, and the second joint 24 is used to be sealed and connected with the external heat-conducting medium, so that the heat-conducting medium flows into the second medium circulation channel 23 through the second joint 24, thereby heating the lower mold frame 5. For example, the medium can be heat-conducting oil. The lower mold frame 5 of the present application realizes precise temperature control of the lower mold frame through an oil temperature heating method, so that the material in the accommodating cavity can be heated to a set temperature, thereby improving and maintaining the quality of the pressed product.

[0053] In one embodiment, the friction plate forming mold of the present application also includes an upper doubler plate 8, which is fixedly connected to the upper mold core 6. The upper doubler plate 8 is configured to be able to move linearly up and down along the vertical direction, thereby jointly driving the upper mold core to move.

[0054] The upper doubler plate 8 is used to be connected to an external driving mechanism, and the driving mechanism drives the upper doubler plate 8 to move linearly up and down in the vertical direction. For example, the driving mechanism can be a hydraulic press, and the upper doubler plate 8 is fixed to the output end of the hydraulic press. Since the output end of the hydraulic press can move linearly up and down in the vertical direction, the upper doubler plate 8 is synchronously driven by the output end of the hydraulic press to move linearly up and down in the vertical direction, so that the convex portion 13 of the upper mold core 6 connected to the upper doubler plate moves linearly up and down in the accommodating cavity 9 in the vertical direction.

[0055] For example, in this embodiment, a heat insulation board 7 is further provided between the upper composite plate 8 and the upper mold core 6, and the heat insulation board 7 is used to insulate when the upper mold core is heated to prevent heat loss. The upper composite plate 8, the heat insulation board 7 and the upper mold core 6 are connected and fixed by a fixing member, and the fixing member can be a screw, a bolt, a pin, etc.

[0056] Further, in this embodiment, the friction plate forming mold of the present application further includes a first guide sleeve 25 and a first guide column 26 adapted thereto, one of the first guide sleeve 25 and the first guide column 26 being fixedly connected to the upper doubler plate 8, and the other of the first guide sleeve 25 and the first guide column 26 being fixedly connected to the lower template 4. For example, the first guide sleeve 25 is fixedly embedded in the upper doubler plate 8, and one end of the first guide column 26 is fixed on the lower template 4. The first guide column 26 is inserted into the first guide sleeve 25. When the upper doubler plate 8 moves linearly up and down in the vertical direction, the first guide sleeve 25 moves linearly up and down on and along the first guide column 26.

[0057] In one embodiment, the friction plate forming mold of the present application also includes a lower ejector plate 2, which is arranged below the lower mold core 3 and fixedly connected thereto. The lower ejector plate 2 is used to connect to a second driving mechanism in the outside world, and is driven by the second driving mechanism to move linearly up and down in the vertical direction, thereby synchronously driving the lower mold core to move linearly up and down in the vertical direction.

[0058] For example, the second driving mechanism may be a cylinder having an output end in the vertical direction, the lower ejector plate 2 is connected to the output end of the cylinder, and is driven by the cylinder to move vertically up and down in a straight line. Therefore, when the lower ejector plate 2 synchronously drives the lower mold core 3 to move vertically up and down in a straight line, the lower mold core 3 can freely pass through the avoidance hole 14 on the lower mold plate 4 to enter the accommodating cavity 9 of the lower mold frame, and cooperate with the upper mold core 6 entering the accommodating cavity 9 to press and solidify the material in the accommodating cavity 9.

[0059] For example, in order to ensure the smooth up and down movement of the lower ejector plate 2, the friction plate forming mold of the present application further includes a second guide sleeve 27 and a second guide column 28, one of which is fixedly connected to the lower ejector plate 2, and the other of which is fixedly connected to the lower double plate 1. For example, the second guide sleeve 27 is fixedly embedded in the lower ejector plate 2, the second guide column 28 passes through the second guide sleeve, and the first end of the second guide column 28 is fixedly connected to the lower double plate 1, and the second end is accommodated in the lower template 4. When the lower ejector plate 2 moves linearly up and down along the vertical direction, the second guide sleeve 27 moves linearly up and down along the second guide column 28 at the same time. The second guide sleeve 27 and the second guide column 28 can ensure that the lower ejector plate 2 can move smoothly up and down along the vertical direction.

[0060] Furthermore, the friction plate forming mold of the present application also includes a lower double plate 1, which is arranged below the lower ejector plate 2 and is connected to the lower template 4 through a fixing member 34 and a spacer plate 29 to ensure space for the lower ejector plate 2 to move. The lower double plate 1 is provided with an avoidance opening 30 for avoiding the operation of the second drive mechanism.

[0061] The friction plate forming mold of the present application is generally placed on a workbench. Specifically, the lower composite plate 1 is fixed on the workbench, and the lower ejector plate 2 is driven by a second driving mechanism on the workbench. The output end of the second driving mechanism can be moved through the avoidance opening 30 and fixedly connected with the lower ejector plate 2.

[0062] For example, a plurality of balancing blocks 33 are fixed on the upper surface of the lower belly plate 1 , and these balancing blocks 33 can ensure that when the lower ejector plate 2 returns to the origin, the balancing blocks are in contact with the lower ejector plate 2 to prevent the lower ejector plate 2 from hitting the lower composite plate 1 .

[0063] In one embodiment, the friction plate forming mold of the present application also includes a first reset rod 31 and a second reset rod 32, the first reset rod 31 is fixedly connected to the upper plate 8, the second reset rod 32 can movably pass through the lower template 4, and the end is fixedly connected to the lower ejector plate 2, wherein the first reset rod 31 and the second reset rod 32 are arranged opposite to each other.

[0064] The first reset rods 31 and the second reset rods 32 are equal in number and are respectively distributed in the circumferential direction of the upper reclosing plate / lower ejector plate and are arranged opposite to each other.

[0065] When the material needs to be pressed by the mold, the upper composite plate 8 synchronously drives the upper mold core 6 to move toward the lower mold frame 5, and at the same time, the lower ejector plate 2 synchronously drives the lower mold core to move toward the lower mold frame 5, that is, the upper mold core 6 and the lower mold core 3 move toward each other. During this process, the first reset rod 31 and the second reset rod 32 also move toward each other until the upper mold core 6 and the lower mold core 3 contact the material and press the material. In this process, the first reset rod 31 and the second reset rod 32 are close to each other until the product is pressed and formed, and the first reset rod and the second reset rod are almost in contact with each other.

[0066] When the pressed product needs to be taken out, the upper plate 8 retreats to open the mold, and the lower ejector plate 2 is driven upward by the second driving mechanism to eject the product from the accommodating cavity 9 and remove the product. Then the upper plate 8 drives the upper mold core 6 to move downward, so that the first reset rod 31 hits the second reset rod 32, so that the second reset rod 32 drives the lower ejector plate 2 and the lower mold core 3 to move downward and retreat to the origin. Wait for the next pressing of the material. By setting the first reset rod 31 and the second reset rod 32, it can be ensured that the lower ejector plate 2 returns to the original position, which plays a safety role.

[0067] The working process of the friction plate forming mold of the present application is described in detail below:

[0068] The lower ejector plate 2 moves upward, synchronously driving the free end of the lower mold core 3 to extend into the accommodating cavity 9 of the lower mold frame 5 to reach the specified position; then the material is placed in the accommodating cavity 9, and at the same time, the upper composite plate 8 synchronously drives the upper mold core 6 to move downward, so that the convex portion 13 of the upper mold core extends into the accommodating cavity 9 to reach the specified position, thereby pressing on the material. At this time, the material is subjected to pressure in the upper and lower directions; the first driving mechanisms 10 on both sides of the accommodating cavity 9 work at the same time, and the piston rod 11 extends, synchronously driving the slider core 12 to extend into the accommodating cavity 9 from the openings 20 on both sides of the accommodating cavity to squeeze the material. At this time, the material is subjected to pressure in four directions: up, down, left and right. At this time, the heat-conducting medium enters the upper mold core 6, the lower mold frame 5 and the lower mold plate 4 respectively, so that the mold reaches the set temperature, and after the pressure is maintained and solidified for a certain period of time, the pressure maintenance is completed, the upper plate 8 returns to the origin, the piston rod 11 of the first drive mechanism 10 drives the slider core 12 to return to the origin, and the lower ejector plate 2 continues to move upward to eject the pressed product from the accommodating cavity 9. Take out the product, separate the friction plate iron parts, and obtain multiple friction plates at the same time. Finally, the upper plate 8 moves downward, so that the first reset rod 31 hits the second reset rod 32 on the lower ejector plate 2, so that the lower ejector plate 2 drives the lower mold core 3 to return to the origin. Wait for the next pressing of the material.
