Description

Technical Field

[0001] The utility model relates to the technical field of brake pad production, in particular to a brake pad steel back U-shaped groove forming die for processing automobile brake pads. Background Art

[0002] Brake pads, also called brake pads, are the most critical safety parts in the car's braking system. They are generally composed of steel plates, bonded insulation layers and friction blocks. The insulation layer is made of non-heat-conducting materials for the purpose of heat insulation; the friction blocks are made of friction materials and adhesives. When braking, they are squeezed against the brake disc and brake drum to generate friction, thereby achieving the purpose of slowing down and braking the vehicle.

[0003] Patent publication number "CN221049100U" discloses a "brake pad forming mold" design, which includes a working box, a plurality of sliding rods fixedly connected to the top of the working box, a supporting plate slidably connected to the sliding rods, a forming mechanism provided on the top of the supporting plate, and two sets of vibration mechanisms symmetrically provided on both sides of the supporting plate. The device separates the formed brake pad from the inner walls of the forming cavity of the upper mold and the lower mold to avoid damage to the formed material caused by direct demolding, but lacks dust-proof settings. When making brake pads, it is necessary to select suitable friction materials, and perform crushing, screening and other treatments, and put the prepared mixture into the brake pad mold. During this process, dust will escape. Being in such an environment for a long time is not good for the health of the staff. In addition, the device lacks centralized collection of the formed brake pads, which reduces work efficiency.

[0038] In this embodiment, when it is necessary to feed the forming mechanism 3, the third motor 216 is started to rotate the third screw 215 to drive the first slide 22 to move upward, and then the lifting plate 21 drives the lower mold 210 to move upward until the shaping box 31 and the lower mold 210 are in contact with each other, and then the first motor 212 is started to rotate the first screw 26 to drive the slide 29 to move backward, and then drive the lower mold 210 to move together, and the lower mold 210 drives the top shaping box 31 to move backward together until the second slides on both sides of the shaping box 31 are in contact with each other. 32 is located at the rear end of the horizontal slide 12.

The molded brake pad falls from the feed hopper 16 to the guide plate 42, and is taken out through the discharge port 43.

[0039] Working principle: When it is necessary to feed the forming mechanism 3, the third motor 216 is started to rotate the third screw 215 to drive the first slide 22 to move upward, and then the lifting plate 21 drives the lower mold 210 to move upward until the shaping box 31 and the lower mold 210 are in contact with each other, and then the first motor 212 is started to rotate the first screw 26 to drive the slider 29 to move backward, and then the lower mold 210 is driven to move together, and the lower mold 210 drives the top shaping box 31 to move backward together until the second slides 32 on both sides of the shaping box 31 are located at the rear end of the horizontal chute 12. At this time, the shaping box 31 and the lower mold 210 are both located below the feeding pipe 63, and then the flow of the feeding pipe 63 is controlled by controlling the valve 64 to complete the feeding; when it is necessary to feed the forming mechanism 3 When the brake pad is being conveyed, the second motor 213 is started to rotate the second screw 27 to drive the push plate 211 to move forward until the molded brake pad on the lower mold 210 is pushed into the feeding hopper 16, and the molded brake pad falls from the feeding hopper 16 to the guide plate 42, and is taken out through the discharge port 43; when the material in the shaping box 31 needs to be hot-pressed, the lifting plate 21 is at the top, the shaping box 31 is in contact with the lower mold 210, and the push plate 211 is located on the rear side of the shaping box 31. First, the first motor 212 is started to rotate the first screw 26. Under the limiting action of the first limiting rod 28, the slider 29 drives the lower mold 210 to move forward. At this time, the shaping box 31 in contact with the lower mold 210 moves forward together. Until the second slide plate 32 slides to one end of the horizontal slide groove 12, at this time the shaping box 31 is located below the upper mold 34, and then the electric push rod 33 is started, so that its output end drives the upper mold 34 to move downward until it fits with the shaping box 31 to hot-press the material in the shaping box 31. During this process, it can be observed through the observation windows 17 on both sides of the working box 11, and the observation windows 17 are in a transparent and sealed state; when demoulding is required, the self-locking motor 55 is first started, so that its output end drives the first rotating shaft 52 to rotate, and the first rotating shaft 52 drives the half gear 53 to rotate, and under the meshing action of the half gear 53 and the rack 54, the working box 11 fixedly connected to the rack 54 is driven to move up and down. Since the bottom of the working box 11 is slidably connected to the connecting rod 57 and its bottom A spring 56 is fixedly connected to the collecting box 41, so that when the half gear 53 and the rack 54 are not engaged, the working box 11 drops due to gravity, squeezing the bottom spring 56, causing the working box 11 to swing up and down, facilitating the disengagement of the molded brake pad in the molding box 31, and at the same time facilitating the flattening of the material during hot pressing and molding. Then the third motor 216 is started to rotate the third screw 215 to drive the first slide 22 to move downward in the vertical slide 13, and then drive the lifting plate 21 fixed to it to move downward. At this time, the lower mold 210 moves downward together. Since the second slides 32 on both sides of the molding box 31 are slidably connected in the horizontal slide 12, the molding box 31 is separated from the lower mold 210. At this time, the molded brake pad is located on the lower mold 210 and is demolded.
