Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake pad processing, and particularly relates to an automobile brake pad forming device. Background Technique

[0002] Automobile brake pads, also known as automobile brake linings, refer to the friction materials fixed on the brake drums or brake discs rotating with the wheels. The friction linings and friction pads therein bear external pressures and generate frictional forces to achieve the purpose of vehicle deceleration. In the production process of brake pads, pressing and forming is an important link.

[0003] At present, the processing and forming process adopted in the market is that workers pour the friction material into the lower die, and then the upper die presses down to hot-press the friction material into brake pads. However, it is not easy to take out the formed brake pads from the lower die after hot-pressing, which reduces the work efficiency. Therefore, there is room for improvement. Content of the Utility Model

[0004] The utility model provides an automobile brake pad forming device to solve the problems put forward in the background technique.

[0005] To solve the above problems, the utility model provides an automobile brake pad forming device, which includes a workbench, an upper die, and a lower die. Above the middle of the workbench, there is a gantry. On the upper surface of the workbench, two slide rails are symmetrically opened. The upper die is installed in the gantry through two first telescopic rods. The lower die is slidably connected to the workbench through two slide rails. On one side surface of the lower die, two second telescopic rods are symmetrically installed, and the two second telescopic rods are installed on the workbench. On the upper surface of the lower die, a number of mold cavities are opened, and an activity cavity is opened at the lower part of the lower die. At the bottom of the mold cavity, there is a template matching the mold cavity. At the bottom of the template, two support rods are symmetrically provided, and the bottom ends of the support rods slidably penetrate through the mold cavity to the activity cavity of the lower die. In the activity cavity, a driving plate is installed through two third telescopic rods. The bottom ends of the support rods are fixedly connected to the upper surface of the driving plate.

[0006] Preferably: On both sides of the mold cavity of the lower die, two limit blocks are symmetrically and fixedly provided, and the upper die is provided with limit grooves matching the limit blocks.

[0007] Preferably: The upper die and the lower die match each other, and a number of pressing blocks matching the mold cavities are fixedly provided on the lower surface of the upper die.

[0009] The beneficial effects of adopting the above technical solutions are:

[0010] 1. During use, the friction material is fed into the mold cavity of the lower mold. The lower mold is driven by the second telescopic rod to slide along the slide rail to directly below the upper mold in the gantry. The upper mold is driven by the first telescopic rod to press down in cooperation with the pressing block to press and form the brake pads in the mold cavity, which is convenient for feeding and hot pressing forming.

[0011] 2. The third telescopic rod drives the driving plate to move upward, and then the template in the mold cavity is driven to move upward by the support rod, and then the formed brake pads are ejected from the mold cavity, improving the material taking efficiency.

[0020] As Figures 1-4 , in this embodiment, an automotive brake pad forming device includes a workbench 1, an upper mold 2, and a lower mold 3. Above the middle of the workbench 1, a gantry 4 is provided. On the upper surface of the workbench 1, two slide rails 11 are symmetrically opened. The upper mold 2 is installed in the gantry 4 through two first telescopic rods 21. The lower mold 3 is slidably connected to the workbench 1 through the two slide rails 11. On one side surface of the lower mold 3, two second telescopic rods 31 are symmetrically installed, and the two second telescopic rods 31 are installed on the workbench 1. On the upper surface of the lower mold 3, a plurality of mold cavities 32 are opened, and a movable cavity 5 is opened at the lower part of the lower mold 3. At the bottom of the mold cavity 32, a template 33 matching the mold cavity 32 is provided. At the bottom of the template 33, two support rods 34 are symmetrically provided, and the bottom ends of the support rods 34 slidably pass through the mold cavity 32 into the movable cavity 5 of the lower mold 3. In the movable cavity 5, a driving plate 6 is installed through two third telescopic rods 61. The bottom end of the support rod 34 is fixedly connected to the upper surface of the driving plate 6.

[0021] Through the above technical solution, when in use, the friction material is introduced into the mold cavity 32 of the lower mold 3, and the material is located above the template 33. Then, the lower mold 3 is driven by the second telescopic rod 31 to move along the slide rail 11 on the workbench 1. Through the setting of the slide rail 11, the movement of the lower mold 3 is restricted, so that it stably moves to directly below the upper mold 2. The upper mold 2 is driven by the first telescopic rod 21 to move downward, and then the friction material in the mold cavity 32 of the lower mold 3 is hot-pressed and formed. After the hot-pressing and forming is completed, the upper mold 2 returns to the initial position under the drive of the first telescopic rod 21. Then, the second telescopic rod 31 drives the lower mold 3 to move out from below the gantry 4 and return to the initial position. Then, the third telescopic rod 61 drives the driving plate 6 to move upward in the movable cavity 5, and then drives the support rod 34 to move upward to drive the template 33 to move in the mold cavity 32, and the formed brake pads are ejected from the mold cavity 32, which is convenient for taking materials and at the same time convenient for loading materials, effectively improving the work efficiency.

[0022] Preferably: On both sides of the mold cavity 32 of the lower mold 3, two limiting blocks 35 are symmetrically and fixedly provided, and the upper mold 2 is provided with a limiting groove 22 matching the limiting blocks 35.

[0023] Through the above technical solution, the matching setting of the limiting block 35 and the limiting groove 22 facilitates the limitation when the upper die 2 and the lower die 3 are pressed together, thereby ensuring the hot pressing forming effect.

[0024] Preferably: The upper die 2 and the lower die 3 are matched, and a pressing block 23 matching the mold cavity 32 is fixedly arranged on the lower surface of the upper die 2.

[0025] Through the above technical solution, the pressing block 23 facilitates the hot pressing forming of the friction material by the mold cavity 32, improving the forming effect.

[0026] Preferably: A spring 36 is sleeved at the end of the support rod 34 located in the movable cavity 5.

[0027] Through the above technical solution, the spring 36 sleeved on the support rod 34 facilitates ensuring the stability of the template 33 in the mold cavity 32, thereby ensuring the stability of the brake pad formed in the mold cavity 32.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than limiting the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above embodiments, those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced, and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention should be covered by the scope of the claims of the present invention; the technologies not described in detail in the present invention are implemented with the prior art.
