[0003] Friction plate is mainly formed by the mixture of bonding system, reinforcing system and friction lubricating system, and needs to be molded, and the prior art is that friction plate is bonded and solidified with metal matrix after being formed separately, and the process is complex and tedious, and the production efficiency is low.Therefore, it is crucial to develop a motor friction plate integrated forming die. UTILITY MODEL CONTENT

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a motor friction plate integrated forming die, which aims at solving the problems of complex and tedious friction plate pressing process and low production efficiency in the prior art.

[0005] The utility model solves the technical scheme that the technical problem thereof adopts: a motor friction plate integrated forming die, including cavity and setting in cavity upper limit block, lower limit block, upper pressure head, lower pressure head, upper rubber pad and lower rubber pad, wherein: the lower rubber pad is arranged at the bottom of the cavity, the lower limit block is placed above the lower rubber pad, the lower pressure head is arranged between the lower limit block and the side wall of the cavity, and the lower pressure head is in contact with the cavity below;Motor friction plate steel body, upper limit block and upper rubber pad are placed in turn above the lower limit block, and the upper pressure head is arranged above the motor friction plate steel body and between the upper limit block and the side wall of the cavity.

[0006] Further, the pad is arranged on the upper pressure head.

[0007] Further, the upper surface of the upper rubber pad is higher than the upper surface of the pad.

[0008] Further, the upper surface of the upper rubber pad is higher than the upper surface of the pad.

[0009] Further, the round hole for inserting the screw rod during demolding is arranged at the bottom of the cavity.

[0010] Further, the handle is arranged on the outer side wall of the cavity.

[0011] Further, the lower end surface of the upper limit block is tightly combined with the upper end surface of the motor friction plate steel body.

[0012] Furthermore, the upper end face of the lower limit block is tightly fitted together with the lower end face of the motor friction plate steel body.

[0013] Compared with the prior art, the positive effects of this utility model are:

[0014] This invention utilizes an upper limit block, a lower limit block, and a rubber pad. During pressing, the lower rubber pad is pressed downwards, causing the lower limit block to move downwards, thus pressing the friction material below the steel body without overflow. Simultaneously, the upper rubber pad is pressed downwards, causing the upper limit block to move downwards, pressing the friction material above the steel body without overflow. Finally, the mold cavity is lifted, a screw is placed in the lower circular hole, and a tile-shaped steel sheet is placed on the upper edge of the mold cavity. Demolding is then completed by pressing downwards. The method of integrally molding motor friction plates using this invention is simple, efficient, and reduces labor intensity. Compared to existing techniques where friction plates are individually molded and then bonded to a metal substrate, this invention provides an integral molding mold for motor friction plates, offering advantages such as simple molding process, high production efficiency, and reduced labor intensity.

[0020] A type of integral molding mold for motor friction plates, such as Figure 1 and Figure 2 As shown, it includes: upper rubber pad 1, pad 2, upper limit block 3, upper pressure head 4, lower pressure head 6, lower limit block 7, lower rubber pad 8, cavity 9, etc., wherein:

[0021] The upper limit block 3 is placed on top of the upper rubber pad 1, and the lower limit block 3 is connected to the motor friction plate steel body 5. The upper limit block 7 is connected to the motor friction plate steel body 5, and the lower limit block 8 is placed below the lower limit block. The upper pressure head 4 is connected to the pad 2 by bolts, mainly to increase the stroke. The lower pressure head 6 is in contact with the cavity 9.

[0022] Furthermore, when the upper rubber pad 1 is pressed, it is compressed, which firmly fixes the upper limit block 3 to the steel body 5 of the motor friction plate, so that the material will not overflow above the motor friction plate.

[0023] Furthermore, when the lower rubber pad 8 is pressed, it is compressed by force, the motor friction plate steel body 5 has downward buffer space, and the lower limit block 7 is tightly combined with the motor friction plate steel body 5, so that no material overflows below the motor friction plate.

[0024] like Figure 3 As shown, a round hole is provided at the bottom of cavity 9 for inserting a screw to facilitate demolding. A handle is provided on the outer wall of cavity 9 to facilitate lifting and moving the mold.

[0025] The method for integrally molding a motor friction plate using the mold of this utility model includes the following steps:

[0026] Step 1: Place the lower rubber pad 8 at the bottom of the cavity 9, place the lower limit block 7 above the lower rubber pad 8, and set the lower pressure head 6 between the lower limit block 7 and the side wall of the cavity 9.

[0027] Step 2: Place the first layer of friction material above the lower pressure head 6, then place the motor friction plate steel body 5, then place the upper limit block 3 above the motor friction plate steel body 5, and then place the second layer of friction material that is exactly the same as the first layer of friction material above the motor friction plate steel body 5 at the position corresponding to the first layer of friction material.

[0028] Step 3: Place the upper pressure head 4 above the second layer of friction material, set the pad 2 on the upper pressure head 4, and place the rubber pad 1 above the upper limit block 3;

[0029] After this step is completed, the superimposed height of the upper rubber pad 1, the upper limit block 3, the motor friction plate steel body 5, the lower limit block 7 and the lower rubber pad 8 is higher than the superimposed height of the pad 2, the upper pressure head 4, the two layers of friction material and the lower pressure head 6, that is, the upper surface of the upper rubber pad 1 is higher than the upper surface of the pad 2.

[0030] Step 4: Start the equipment and press down on the upper rubber pad 1. The upper rubber pad 1 is compressed first, which firmly fixes the upper limit block 3 on the motor friction plate steel body 5, ensuring that there is no material overflow above the motor friction plate. Then the lower rubber pad 8 is also compressed. The motor friction plate steel body 5 has downward buffer space, so that the lower limit block 7 is tightly combined with the motor friction plate steel body 5, ensuring that there is no material overflow below the motor friction plate.

[0031] Step 5: After the upper rubber pad 1 is compressed a certain distance, the pad 2 is driven by the upper pressure head 4 to move downward. With the cooperation of the lower pressure head 6, the two layers of friction material are pressed.

[0032] Step 6: After the motor friction plate material is pressed and formed, release the pressure, raise the press, lift the cavity 9, put the screw into the round hole at the bottom of the cavity, place the tile-shaped steel sheet on the upper edge of the cavity 9, and then press the press down to complete the demolding.

[0033] The working principle of this utility model is as follows: In use, the lower pressure head 6, the lower rubber pad 8, and the lower limit block 7 are placed into the cavity 9 in sequence. Then, the friction material is placed above the lower pressure head 6, followed by the motor friction plate steel body 5. The friction material is then placed above the motor friction plate steel body 5, and finally, the limit block 3, the upper pressure head 4, and the upper rubber pad 1 are placed in sequence. The equipment is started, and the upper rubber pad 1 is pressed down to make the pad 2 and the upper pressure head 4 move downward. After the motor friction plate material is pressed into shape, the pressure is released, the press is raised, the cavity 9 is lifted, and a screw is placed in the round hole below it. A tile-shaped steel sheet is placed on the upper edge of the cavity 9, and demolding is completed when it is pressed downward.
