[0001] This utility model relates to the technical field of brake pad processing, specifically to a brake pad compression molding mechanism. Background Technology
[0002] In the manufacturing process of brake pads, injection molding technology is widely used due to its ability to efficiently achieve composite molding of metal and plastic. The traditional process is usually as follows: a robotic arm places the brake pad metal raw material at a designated position in the moving mold, and then the hydraulic cylinder drives the moving mold to close with the fixed mold, forming a closed molding cavity; then, the injection mechanism injects molten plastic raw material into the molding cavity, and after the plastic raw material cools and solidifies in the cavity, it combines with the metal raw material to form the finished brake pad.
[0003] Currently, during the processing of most brake pads, the plastic raw material is not compressed during the cooling process inside the molding cavity. Therefore, the following disadvantages exist: tiny air bubbles are easily left or insufficient filling at the interface between the plastic and metal raw materials, resulting in a loose bond between the two. Utility Model Content

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] like Figures 1-4 As shown, a brake pad compression molding mechanism includes a machine body 1, which is fixed to the top surface of a base frame 2. A fixed mold 3 is provided above the base frame 2. Several molding cavities 4 are opened on the front side of the fixed mold 3. A hydraulic cylinder is provided inside the machine body 1. A movable plate 5 is fixed to one end of the hydraulic cylinder's telescopic rod. A movable mold 6 is provided behind the movable plate 5. Several movable holes 7 are opened on the front side of the movable mold 6. A cylinder 8 is fixed to the rear side of the movable plate 5. A connecting plate 9 is fixed to one end of the telescopic rod of the cylinder 8. Several movable columns 10 are fixed to the rear side of the connecting plate 9. The several movable columns 10 are slidably inserted into the several movable holes 7 and are respectively... The machine body 1 is equipped with a fixed placement column 11. Several extrusion rods 12 are fixed to the outer walls of several placement columns 11. Arc-shaped blocks 13 are fixed between several extrusion rods 12. The machine body 1 is equipped with a pull door 14. Two mounting plates 15 are fixed between the moving plate 5 and the moving mold 6. The top surface of the base frame 2 is equipped with a fixed plate 16. The front side of the fixed plate 16 is fixedly connected to the rear side of the fixed mold 3. The front side of the fixed plate 16 and the fixed mold 3 are both provided with injection holes 17. The front side of the fixed mold 3 is provided with several guide channels 18. The several guide channels 18 are respectively connected to several molding cavities 4. The top surface of the base frame 2 is equipped with an injection mechanism 19.
[0022] In use, the shape of the molding cavity 4 matches the finished brake pad. With the help of a robotic arm (not shown in the figure), the operator moves several brake pad metal materials through the top of the sliding door 14 into the sliding door 14. Then, the metal materials are placed on the placement column 11 to prepare for the subsequent mold closing process. Next, the hydraulic cylinder is started, and the extension rod of the hydraulic cylinder drives the moving plate 5 to move backward. The moving plate 5 then drives the moving mold 6 to move backward in sync until the moving mold 6 and the fixed mold 3 are tightly closed. At this time, several metal materials are accurately inserted into several molding cavities 4, ensuring that each metal material can be processed in the correct position.
[0023] Subsequently, through the injection mechanism 19, the plastic raw material is injected into the injection hole 17 of the fixed mold 3. The plastic raw material flows into several molding cavities 4 along the guide groove 18 to begin the cooling and molding process. When the plastic raw material is in a semi-solid state, the cylinder 8 is activated. The telescopic rod of the cylinder 8 drives the connecting plate 9 to move backward, which in turn drives several movable columns 10 to move backward inside several movable holes 7. At the same time, it drives several placement columns 11, extrusion rods 12 and arc blocks 13 to extrude into the molding cavity 4. This extrusion action makes the semi-solid plastic raw material subject to uniform and appropriate pressure, which can completely penetrate the microporous structure of the metal raw material surface. This effectively avoids the problem of small air bubbles or insufficient filling at the interface between the plastic raw material and the metal raw material, ensuring a seamless bond between the metal raw material and the plastic raw material interface, and improving the quality and performance of the brake pad.
[0024] Through the coordinated action of the machine body 1, base frame 2, fixed mold 3, molding cavity 4, moving plate 5, moving mold 6, movable hole 7, cylinder 8, connecting plate 9, movable column 10, placement column 11, extrusion rod 12, and arc block 13, the brake pad achieves precise extrusion of plastic raw material during the molding process. This allows the plastic raw material to fully penetrate the microporous structure of the metal raw material surface, solving the problem that easily occurs at the interface between the plastic and metal raw materials, ensuring a tight and seamless bond between the two, and thus improving the quality of the brake pad.
[0025] like Figures 1-4 As shown, a limiting hole 20 is provided on the front side of the moving mold 6, and a limiting rod 21 is fixed on the rear side of the connecting plate 9. The limiting rod 21 is slidably inserted into the limiting hole 20.
[0026] During use, when the connecting plate 9 moves back and forth via the cylinder 8, the limiting rod 21 slides inside the limiting hole 20, which limits the connecting plate 9 and ensures that the connecting plate 9 will not deviate or shake during the back and forth movement, thus improving stability.
[0027] like Figures 1-4 As shown, the rear side of the moving mold 6 is fixed with several positioning pins 22, and the front side of the fixed mold 3 is provided with several positioning holes 23, which respectively position several positioning pins 22.
[0028] During use, when the moving plate 5 drives the moving mold 6 to move backward and close with the fixed mold 3, the positioning pin 22 will accurately insert into the positioning hole 23. This action can assist in positioning the moving mold 6, so that the moving mold 6 can accurately fit with the fixed mold 3, effectively avoiding the problem of inaccurate mold closing caused by the position deviation of the moving mold 6.
[0029] like Figure 1 , Figure 2 and Figure 4As shown, a PLC controller 24 is fixed to the rear side of the sliding door 14. The PLC controller 24 is a Siemens S7-200. A support frame 25 is fixed to the top surface of the PLC controller 24. A lighting lamp 26 is fixed to the top surface inside the support frame 25. Observation holes 27 are opened on the left and right sides of the sliding door 14. Observation plates 28 are fixed inside the two observation holes 27.
[0030] During operation, the PLC controller 24 is the core of the entire equipment. When the equipment operates in poorly lit environments, the lighting 26 emits bright light, evenly illuminating the area around the PLC controller 24 and providing ample illumination for the staff. The observation panel 28 is made of transparent acrylic sheet, allowing staff to monitor the equipment's internal operating status in real time, such as the accuracy of metal material placement, the smoothness of the mold closing process, the uniformity of plastic material injection, and the normality of the product molding process. Through the observation hole 27 and the observation panel 28, staff can directly observe everything inside without opening the sliding door 14.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
