[0013] Four upright posts, the four upright posts being inserted and fixed on the base;

[0014] A movable plate, the movable plate being horizontally sleeved on the four upright posts; cylinder mounting grooves are provided on both sides of the movable plate;

[0015] a first movable plate oil cylinder, wherein a cylinder body of the first movable plate oil cylinder is installed in the center of the base, and a telescopic rod of the first movable plate oil cylinder is connected to the movable plate;

[0016] Two second movable plate oil cylinders, the cylinder bodies of the two second movable plate oil cylinders are respectively installed on both sides of the base, and the telescopic rods of the two second movable plate oil cylinders are connected to the movable plate;

[0017] A mold shifting mechanism, the mold shifting mechanism being mounted on the upper portion of the movable plate;

[0018] A neutron frame, which is sleeved on the four uprights and located above the movable plate; a slide groove is provided on the inner side of the neutron frame;

[0019] An upper seat, the upper seat being fixed at a position close to the top of the four columns; a fixed mold, the fixed mold being installed at the bottom of the upper seat corresponding to the movable mold;

[0020] The bottom of the fixed mold is provided with a hot plate;

[0021] a controller fixed on the mounting platform; the controller is controlled by a PLC and is electrically connected to the first movable plate oil cylinder, the second movable plate oil cylinder, and the mold shifting mechanism;

[0022] Two mounting screw holes are provided and are located at the top ends of the two outer side walls of the neutron frame. The mounting screw holes are used to connect the automatic hot press with the conveying mechanism.

[0023] The hot press controller is installed on the other side of the hot press platform and the conveying mechanism, is controlled by a PLC, and is electrically connected to the hot press, the automatic filler, and the conveying mechanism.

[0024] On the other hand, the present invention also provides a production method for hot pressing a brake pad, which adopts the production system for hot pressing a brake pad, and comprises the following steps:

[0025] By driving the motor to rotate, the driving gear and the driven gear are driven to rotate, thereby driving the crawler belt engaged with the gear to move, so that the movable mold on the crawler belt moves;

[0026] When the movable mold moves to the bottom of the automatic filling machine, the sensor on the filling machine detects the movable mold and the drive motor stops rotating. At this time, the filling operation is carried out;

[0027] After the filling is completed, the driving motor continues to rotate, and the movable mold moves to the mold-moving mechanism of the automatic hot press. The driving motor stops rotating, and the mold-moving mechanism transports the movable mold to the top plate for heating and pressing operations.

[0028] After the hot pressing is completed, the movable mold returns to the conveying mechanism through the mold moving mechanism, and the driving motor rotates again to allow the movable mold to cool naturally on the conveying mechanism;

[0029] After cooling, the movable mold moves to the top of the finished product collector, and is demoulded by inversion, and the finished product automatically falls into the finished product collector;

[0030] At least four movable molds are installed on the crawler, and the four movable molds can be in the filling, hot pressing, cooling and mold moving operations at the same time.

[0031] Compared with the prior art, the beneficial effect of the present invention is that: by driving the motor to rotate, the driving gear and the driven gear are driven to rotate, thereby driving the crawler engaged with the gear to move, and at least four movable molds are installed on the crawler. At the same time, the four movable molds can be in filling, hot pressing, cooling, and mold moving operations respectively. When the first movable mold moves to the bottom of the automatic filling machine, the sensor on the filling machine detects the movable mold, and the driving motor stops rotating. At this time, the second movable mold is directly below the hot press, the third movable mold is behind the hot press, above the crawler, and the fourth movable mold is above the finished product collector, inverted below one end of the crawler, and demolding is performed by inversion. Next, the automatic filling machine starts filling, and the automatic hot press starts heating and pressing. The third movable mold on the crawler cools naturally, and the fourth movable mold inverted below one end of the crawler is demolded by inversion. By cleverly distributing the movable molds, the integrated operation of filling, hot pressing, cooling, and mold moving can be achieved, which reduces the conversion time and cost between processes and improves work efficiency.

[0032] The automatic filling machine of the present invention is controlled by PLC. When the sensor on the automatic filling machine detects that the movable mold moves to the specified position, the PLC controls the driving motor in the transmission mechanism to stop rotating. At this time, the solenoid valves on the six discharge ports below the raw material bin open and close according to the predetermined time, which can realize quantitative filling and ensure the consistency of the filling amount each time, thereby improving the consistency of product quality. This process is controlled by PLC, which can realize accurate detection of the position of the movable mold and precise control of the rotation of the driving motor, ensuring the accuracy and stability of the filling operation. The entire filling process does not require manual intervention, greatly improving production efficiency, reducing labor costs, and reducing human errors. The raw material bin can be adjusted in height on the four filling machine columns, and the position of the discharge port below the raw material bin and the height of the raw material bin can be adjusted according to different products. The scheduled time for the opening and closing of the solenoid valve can be adjusted according to actual production needs, which can adapt to the filling requirements of different products and increase production flexibility.

[0033] The platform above the base of the automatic hot press is equipped with a groove that runs through the base and fits snugly with the conveyor mechanism. The automatic hot press is controlled by a programmable logic controller (PLC). When the machine's sensors detect that the movable mold has reached a designated position, the PLC stops the drive motor in the conveyor mechanism. At this point, the press's built-in electromagnetic induction heating assembly begins heating the upper mold. A hydraulic lever then pushes the upper mold downward, holding it in place for several seconds before raising it to its starting position. After that, the conveying mechanism continues to move. When the next movable mold is hot-pressed, the movable mold that has completed hot pressing cools down naturally on the conveying mechanism. Finally, it is automatically demoulded by flipping, and the finished product automatically falls into the finished product collector. This process does not require manual removal of the mold, which improves production efficiency and reduces the possibility of workers getting burned when taking the mold in the hot press. The electromagnetic induction heating component has a fast heating speed and high efficiency, can quickly reach the required heating temperature, shortens the production cycle, and the continuous movement of the conveying mechanism enables one movable mold to be hot-pressed while the previous movable mold can be naturally cooled and demoulded, realizing seamless connection of the production process, maximizing the use of time and space, and further improving overall production efficiency.

[0050] It can be understood that when the sensor on the automatic filling machine 4 detects that the movable mold 6 moves to the specified position, the PLC controls the drive motor in the conveying mechanism to stop rotating. At this time, the solenoid valves on the six discharge ports 43 below the raw material bin open and close according to the predetermined time to achieve quantitative filling.

[0051] Reference Figure 3As shown, the automatic hot press 500 includes: a frame 501, a base 502, a column 503, a movable plate 504, a first movable plate cylinder 505, a second movable plate cylinder 506, a mold moving mechanism 507, a neutron frame 508, an upper seat 509, a fixed mold 510, and a controller 511 with mounting screw holes 510;

[0053] It is understood that when the sensors of the automatic hot press 500 detect that the movable mold has reached the mold transfer mechanism, the PLC controls the drive motor in the conveyor mechanism to stop. At this point, the automatic hot press 500 controls the mold transfer mechanism 507 to transfer the movable mold 600 to the fixed mold 510.

After hot pressing is complete, the mold transfer mechanism 507 transfers the movable mold 600 back to the conveyor mechanism 100, completing the automatic hot pressing process for brake pad production.

[0054] In another embodiment based on the above embodiment, this embodiment provides a production method for hot pressing a brake pad. The method adopts the production system for hot pressing a brake pad in the above embodiment, and includes the following steps:

[0055] By driving the motor to rotate, the driving gear and the driven gear are driven to rotate, thereby driving the crawler 300 engaged with the gear to move, so that the movable mold 600 on the crawler 300 moves;

[0056] When the movable mold 600 moves to the bottom of the automatic filling machine 400, the sensor on the automatic filling machine 400 detects the movable mold 600, and the driving motor stops rotating. At this time, the filling operation is performed;

[0057] After the filling is completed, the driving motor continues to rotate, and the movable mold 600 moves to the mold moving mechanism 507 of the automatic hot press 500. The driving motor stops rotating, and the mold moving mechanism 507 transports the movable mold 600 to the top plate for heating and pressing operations.

[0058] After the hot pressing is completed, the driving motor rotates again to allow the movable mold 600 to cool naturally on the conveying mechanism 100;

[0060] At least four movable molds 600 are installed on the crawler 300. At the same time, the four movable molds 600 can be in the filling, hot pressing, cooling, and mold moving operations at the same time.

[0061] In the above embodiment, the automatic filler 400 is controlled by a PLC. When the sensor on the automatic filler 400 detects that the movable mold 600 moves to the specified position, the PLC controls the drive motor in the conveying mechanism 100 to stop rotating. At this time, the solenoid valves on the six discharge ports 430 below the raw material bin are opened and closed according to the predetermined time, which can realize quantitative filling and ensure the consistency of the filling amount each time, thereby improving the consistency of product quality. This process is controlled by the PLC, which can realize accurate detection of the position of the movable mold 600 and precise control of the rotation of the drive motor, ensuring the accuracy and stability of the filling operation. The entire filling process does not require manual intervention, greatly improving production efficiency, reducing labor costs, and reducing human errors.

The automatic hot press 500 controls the mold-moving mechanism 507 to transport the movable mold 600 to the fixed mold 510. Then, the hot plate on the fixed mold 510 heats the movable mold. After the heating is completed, hot pressing begins. After the hot pressing is completed, the mold-moving mechanism 507 transports the movable mold 600 back to the conveying mechanism 100. Thereafter, the conveying mechanism 100 continues to move.
