Description

Technical Field

[0001] This utility model relates to the field of brake pad technology, specifically to brake pad hot-pressing film. Background Technology

[0002] Brake shoes are key friction components in braking systems, used to achieve mechanical deceleration or stopping through friction. Brake shoes are components in the brake that come into contact with rotating parts. They generate braking torque through friction, converting kinetic energy into heat energy, thereby achieving braking. They convert external forces, such as hydraulic, pneumatic, or mechanical forces, into frictional forces, consuming mechanical energy through friction, thus slowing down equipment or vehicles, preventing excessive wear or thermal fade, and ensuring the reliability of the braking system.

[0003] In existing technology, the original mold is a single-layer heating plate structure. Due to the limitation of the press tonnage, it is difficult to improve production efficiency. If the number of mold holes is increased to increase output, a large-tonnage press with a large table is required. Moreover, the large-tonnage press with a large table consumes a lot of energy and the mold manufacturing cost is high. Therefore, it is necessary to improve the design and use the original small-tonnage press to achieve the effect of a single-layer multi-hole mold of a large-tonnage press with a large table. Therefore, we proposed the brake shoe hot pressing film. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figs. 1-2The brake pad hot-pressing film includes a base 1. A mold seat 2 is precisely machined to ensure a smooth and gapless contact surface with the base 1 at the upper end of the base 1. A lower mold seat 4 is also precisely machined to the upper end of the mold seat 2. The mold seat 2 and the lower mold seat 4 are connected by a connecting device. The connecting device includes connecting ears fixedly connected to the side wall of the mold seat 2. The connecting ears are made of thickened steel plate to ensure connection strength. Another corresponding connecting ear is fixedly connected to the lower end of the lower mold seat 4. This connecting ear maintains an assembly tolerance of less than 0.1mm with the connecting ear on the mold seat 2. Both connecting ears have through-holes. The inner walls of the connecting holes are polished to reduce bolt wear. Connecting bolts 3, made of 12.9 grade high-strength bolts, are fitted into the connecting holes to ensure a stable and reliable connection.

[0019] The lower mold base 4 has multiple mold cavities 13 running through it. These cavities are precision milled using a CNC machining center, achieving a dimensional accuracy of ±0.02mm. Multiple sealing devices are fixedly connected to the upper end of the base 1 at corresponding positions. These sealing devices are made of high-temperature silicone material, effectively preventing material overflow during hot pressing. The sealing devices include multiple base plates 10 fixedly connected to the base 1. The surface of each base plate 10 is covered with a Teflon coating, providing excellent anti-stick properties. The shapes of the multiple base plates 10 correspond to the shape of the brake shoe template 7, ensuring uniform pressure distribution. Each base plate 10 is located within a specific mold cavity 13 and is sealed to the inner wall of that cavity. The mating surfaces are precision ground to achieve a surface roughness of Ra0.8μm. Each base plate 10 is connected to the base 1 via corresponding fixing bolts 11. These fixing bolts are designed to prevent loosening under long-term vibration.

[0020] Specifically, an upper mold base 9 is located above the lower mold base 4, and a pressure sensor is installed on the upper mold base 9 to monitor the pressing pressure in real time. A temperature control device is installed throughout the lower mold base 4, and the temperature control device adopts a PID automatic control system with a temperature control accuracy of ±1℃. The temperature control device includes multiple heating ring channels 5 installed throughout the lower mold base 4, and the heating ring channels 5 have built-in high-efficiency heating wires that can reach the set temperature within 30 seconds. Multiple temperature control ring channels 6 are installed throughout the lower mold base 4 at the same location. The coolant circulating in the temperature control ring channels 6 uses a special formula and has excellent thermal conductivity. The multiple heating ring channels 5 and multiple temperature control ring channels 6 are designed to cross each other, and this cross layout ensures uniform temperature distribution in the working area. Multiple mold cavities 13 are equipped with multiple stacked brake pad templates 7, and each template 7 is quenched to a hardness of HRC58 or higher.

[0021] Specifically, a dust collection hood 12 is additionally designed on the upper side of the upper mold base 9. The dust collection hood 12 is connected to the central dust removal system, which can effectively collect the dust generated during the pressing process. Multiple mold cavities 13 are filled with mold liners 8, which are made of nanocomposite materials and have a service life of up to 20,000 pressing cycles.

[0022] In this utility model, multiple base plates 10 are designed between the base 1, the mold base 2, and the lower mold base 4 to correspond to each mold cavity 13, ensuring the material removal of each mold cavity 13 in the later stage and adding an extra mold layer to facilitate hot pressing operation. The cross design of multiple heating rings 5 ​​and multiple temperature control rings 6 during hot pressing makes hot pressing simpler. The mold liner 8 designed in each mold cavity 13 is made of stainless steel, which can facilitate demolding.
