Description

Technical Field

[0001] This utility model relates to the technical field of brake pad production, specifically to an injection molding mechanism for brake pad production. Background Technology

[0002] In the production process of brake pads, injection molding technology is a common method. Typically, a robotic arm places the metal raw material on the moving mold, and then the moving mold and the fixed mold are closed by a hydraulic cylinder. Subsequently, the plastic raw material is injected into the molding cavity by an injection mechanism, so that the plastic raw material and the metal raw material are connected. After cooling, the mold is formed.

[0003] Currently, most brake pads are produced by injection molding, which typically involves connecting cooling pipes to the fixed mold and then supplying cooling water to the fixed mold through the cooling pipes to dissipate heat between the fixed mold and the molded part. However, this method has the following drawbacks: the fixed mold relies on only a single cooling water channel, resulting in poor heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide an injection molding mechanism for brake pad production, which solves the problem of poor heat dissipation when the fixed mold relies on only a single cooling water channel.

[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an injection molding mechanism for brake pad production, comprising a machine body, the machine body being fixed to the top surface of a base frame, a sliding door being provided inside the machine body, a through hole being opened on the top surface of the sliding door, a fixed plate being fixed to the top surface of the base frame, a fixed mold being fixed to the front side of the fixed plate, two cooling holes being opened on the right side of the fixed mold, heat pipes being fixed to both cooling holes, cooling pipes being fixed to the left and right ends of both heat pipes, heat dissipation grooves being opened on the top and bottom surfaces of the fixed mold, heat dissipation fins being fixed inside both heat dissipation grooves, and a plurality of heat dissipation channels being opened on the top and bottom surfaces of the fixed mold, the plurality of heat dissipation channels being connected to the heat dissipation grooves.

[0006] Preferably, the fixed mold and the fixed plate have injection holes on their front sides, the fixed mold has several guide grooves on its front side, and the guide grooves are respectively connected to the injection holes. The fixed mold has several molding cavities on its front side, and the molding cavities are respectively connected to the guide grooves. The machine body has a hydraulic cylinder inside, one end of the hydraulic cylinder's telescopic rod is fixed to a moving plate, the rear side of the moving plate is fixed to a moving mold, the rear side of the moving mold has protrusions corresponding to the molding cavities, and the top surface of the base frame has an injection mechanism.

[0007] Preferably, a number of positioning pins are fixed on the rear side of the moving mold, and a number of positioning holes are opened on the front side of the fixed mold, with the positioning holes respectively positioning the positioning pins.

[0008] Preferably, the fixed plate is connected and fixed to the machine body by a number of guide posts, and the front side of the movable plate is provided with a number of guide holes. The movable plate is slidably mounted on the number of guide posts through the number of guide holes.

[0009] Preferably, observation holes are provided on both the left and right sides of the sliding door, and a transparent plate is fixed inside each of the two observation holes.

[0010] Preferably, a U-shaped frame is fixed to the right side of the sliding door, and a rubber sleeve is fixed to the outer wall of the U-shaped frame.

[0011] Compared with existing technologies, the injection molding mechanism for brake pad production that adopts the above technical solution has the following advantages:

[0012] 1. In use, through the synergistic effect of the machine body, base frame, sliding door, through hole, fixed plate, fixed mold, cooling hole, heat pipe, cooling tube, heat dissipation groove, heat dissipation fin and heat dissipation flow channel, multiple heat dissipation methods are achieved for the fixed mold. Compared with the traditional mold that relies on a single cooling water channel for heat dissipation, the heat dissipation efficiency of the fixed mold and the molded part is improved. The rapid heat dissipation can shorten the cooling time of the product, improve production efficiency, and at the same time ensure the quality stability of the product.

[0013] Second, during use, it can assist in positioning the moving mold, ensuring accurate fitting between the moving mold and the fixed mold, thus avoiding inaccurate mold closing caused by positional deviation of the moving mold. It can also limit the movement of the moving plate, ensuring that the moving plate and moving mold do not shift or wobble during forward and backward movement.

[0014] Third, during use, staff can see everything inside without opening the sliding door, enabling them to promptly identify problems that arise during production. When staff hold the U-shaped frame, the rubber sleeve provides a comfortable grip, reducing discomfort from direct contact between the hand and the metal U-shaped frame. Attached Figure Description

[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, an injection molding mechanism for brake pad production includes a machine body 1, which is fixed to the top surface of a base frame 2. The machine body 1 has a sliding door 3 inside, with a through hole 4 on its top surface. A fixed plate 5 is fixed to the top surface of the base frame 2, and a fixed mold 6 is fixed to the front side of the fixed plate 5. Two cooling holes 7 are opened on the right side of the fixed mold 6, and heat pipes 8 are fixed to both cooling holes 7. Cooling pipes 9 are fixed to the left and right ends of the two heat pipes 8. Heat dissipation grooves 10 are opened on the top and bottom surfaces of the fixed mold 6, and heat dissipation fins 11 are fixed inside the two heat dissipation grooves 10. Several heat dissipation channels 12 are opened on the top and bottom surfaces of the fixed mold 6. Several heat dissipation channels 12 are connected to heat dissipation grooves 10. Injection holes 13 are opened on the front side of the fixed mold 6 and the fixed plate 5. Several guide grooves 14 are opened on the front side of the fixed mold 6, and the several guide grooves 14 are respectively connected to the injection holes 13. Several molding cavities 15 are opened on the front side of the fixed mold 6, and the several molding cavities 15 are respectively connected to the several guide grooves 14. A hydraulic cylinder is provided inside the machine body 1. A moving plate 16 is fixed at one end of the hydraulic cylinder telescopic rod. A moving mold 17 is fixed at the rear side of the moving plate 16. A protrusion corresponding to the several molding cavities 15 is provided at the rear side of the moving mold 17. An injection mechanism 18 is provided on the top surface of the base frame 2.

[0022] During use, the operator uses a robotic arm (not shown in the figure) to move several brake pad metal materials through the through hole 4 into the sliding door 3. Then, the metal materials are placed on several protrusions of the moving mold 17 to prepare for the subsequent mold closing process. Next, the hydraulic cylinder is activated, and the extension rod of the hydraulic cylinder drives the moving plate 16 to move backward, which in turn drives the moving mold 17 to move backward, so that the moving mold 17 and the fixed mold 6 are tightly closed. At this time, several metal materials are accurately inserted into several molding cavities 15. Then, through the injection mechanism 18, the plastic material is injected into the injection hole 13 of the fixed mold 6. The plastic material flows into several molding cavities 15 along the guide groove 14 and begins the cooling and molding process.

[0023] During the cooling and molding stage, the workers connect the cooling pipe 9 to the cooling water delivery pipe (not shown in the figure). The cooling water is delivered to the heat pipe 8 through the cooling pipe 9. The heat pipe 8 utilizes its efficient thermal conductivity to quickly transfer the heat generated by the fixed mold 6 to the cooling water. The cooling water carries away the heat and flows out, achieving initial heat dissipation for the fixed mold 6. At the same time, the heat sinks 11 on the top and bottom surfaces of the fixed mold 6 are made of aluminum. Aluminum has good thermal conductivity and can quickly absorb the heat of the fixed mold 6. It can also dissipate the heat to the surrounding environment through its large surface area, further enhancing the heat dissipation effect. In addition, the design of the heat dissipation channel 12 expands the heat dissipation area, allowing the heat to come into more full contact with the air and accelerating the heat loss, thereby further improving the heat dissipation efficiency.

[0024] Through the synergistic effect of the body 1, base frame 2, sliding door 3, through hole 4, fixed plate 5, fixed mold 6, cooling hole 7, heat pipe 8, cooling pipe 9, heat dissipation groove 10, heat dissipation fin 11 and heat dissipation flow channel 12, multiple heat dissipation methods are achieved for the fixed mold 6. Compared with the traditional mold that relies on a single cooling water channel for heat dissipation, the heat dissipation efficiency of the fixed mold 6 and the molded part is improved. The rapid heat dissipation can shorten the cooling time of the product, improve production efficiency, and at the same time ensure the quality stability of the product.

[0025] like Figures 1-3 As shown, the rear side of the moving mold 17 is fixed with several positioning pins 19, and the front side of the fixed mold 6 is provided with several positioning holes 20, which respectively position several positioning pins 19.

[0026] In use, when the moving plate 16 drives the moving mold 17 to move backward and close with the fixed mold 6, the positioning pin 19 is inserted into the positioning hole 20, which can assist in positioning the moving mold 17, so that the moving mold 17 can accurately fit with the fixed mold 6, avoiding the problem of inaccurate mold closing caused by the position deviation of the moving mold 17.

[0027] like Figures 1-3 As shown, a number of guide posts 21 are fixedly connected between the fixed plate 5 and the body 1. A number of guide holes 22 are opened on the front side of the movable plate 16. The movable plate 16 is slidably mounted on the guide posts 21 through the guide holes 22.

[0028] During use, when the moving plate 16 and the moving mold 17 move back and forth via the hydraulic cylinder, the moving plate 16 slides on the guide post 21, which limits the movement of the moving plate 16 and ensures that the moving plate 16 and the moving mold 17 do not deviate or shake during the back and forth movement.

[0029] like Figure 1 , Figure 2 and Figure 4As shown, observation holes 23 are provided on both the left and right sides of the sliding door 3. A transparent plate 24 is fixed inside each of the two observation holes 23. A U-shaped frame 25 is fixed on the right side of the sliding door 3, and a rubber sleeve 26 is fixed on the outer wall of the U-shaped frame 25.

[0030] During use, the transparent plate 24 is made of transparent plastic. Operators need to monitor the internal operating status of the equipment in real time, such as the placement of metal raw materials, the accuracy of mold closing, the injection of plastic raw materials, and the product molding process. Through the observation hole 23 and the transparent plate 24, operators can directly see everything inside without opening the sliding door 3, enabling them to promptly identify problems during production. The U-shaped frame 25 fixed to the right side of the sliding door 3 provides a convenient operating handle for operators. When opening or closing the sliding door 3, operators can hold the U-shaped frame 25, improving operational convenience and efficiency. The rubber sleeve 26 provides excellent protection and comfort. With its soft texture and good elasticity, the rubber sleeve 26 offers a comfortable grip when operators hold the U-shaped frame 25, reducing discomfort from direct contact between the hand and the metal U-shaped frame 25.

[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.
