Description

Technical Field

[0001] This utility model belongs to the field of die casting technology, and relates to edge trimming, specifically a die casting edge trimming mold. Background Technology

[0002] After die casting, excess metal parts often need to be removed, such as gates and flash generated during casting. These excess parts are called "trimming." The main function of trimming dies is to precisely cut die castings to ensure that the final product's appearance and dimensions meet design requirements. They are typically made of high-strength materials and designed to withstand high pressure and impact to ensure the efficiency and accuracy of the trimming process. Suitable trimming dies can improve production efficiency, reduce scrap rates, and ensure product quality.

[0003] However, some existing die-casting trimming dies can only trim one die-casting part at a time, which requires frequent replacement of the die-casting part during the trimming process, thus reducing production efficiency. This is especially true in mass production, where the potential of the die cannot be fully utilized. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a die-casting trimming mold. The technical problem this utility model aims to solve is that typically only one die-casting part can be trimmed, which leads to frequent replacement of the die-casting part during the trimming process, thus reducing production efficiency. This is especially true in mass production, where the potential of the mold cannot be fully utilized.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A die-casting trimming mold includes a base, a first U-shaped plate fixedly connected to the top of the base, a second U-shaped plate disposed on the top of the first U-shaped plate, two transmission belts disposed on symmetrical sides of the first and second U-shaped plates, and the two transmission belts are configured to cooperate with each other, side plates fixedly connected to both sides of the second U-shaped plate, a lifting mechanism for raising and lowering the second U-shaped plate is provided at the bottom of the two side plates, a limit plate fixedly connected to the surface of the two transmission belts, and multiple limit plates are arranged in pairs, and a rotating mechanism for rotating the transmission belts is provided on one side of the two transmission belts. The arrangement of the two transmission belts can ensure that multiple die-casting parts can be trimmed continuously.

[0007] As a further embodiment of this utility model, the lifting mechanism includes two second rollers, both of which are fixedly connected to the top of the base. The side plate is slidably sleeved on the surface of the two limiting posts. A hydraulic rod is fixedly connected to the top of the base on the side near the two limiting posts. The output ends of the two hydraulic rods are fixedly connected to the bottom of the side plate. By setting the hydraulic rods, the upper transmission belt can be lifted and lowered.

[0008] As a further embodiment of this utility model, the rotating mechanism includes four first rollers, which are rotatably connected to one side of the first U-shaped plate and the second U-shaped plate, respectively. The first rollers are arranged in pairs, and the two transmission belts are respectively sleeved on the surfaces of the two sets of first rollers. Each set of first rollers has a rotating mechanism for rotating the first roller on one side. The transmission belts can be rotated by the arrangement of the first rollers.

[0009] As a further embodiment of this utility model, the rotating mechanism includes a first synchronous pulley, which is fixedly connected to one end of one of the first rollers. A second motor is fixedly connected to the base and the surface of the second U-shaped plate near the first synchronous pulley. The output shaft of the second motor is fixedly connected to the second synchronous pulley. The surfaces of the second and first synchronous pulleys are fitted with the same synchronous belt. Multiple second rollers are rotatably connected inside the first and second U-shaped plates near the transmission belt, and all the second rollers cooperate with the transmission belt. An extrusion plate is fixedly connected to one side of both the first and second U-shaped plates, and both extrusion plates cooperate with the transmission belt. A first motor is fixedly connected to the top of the base away from the extrusion plate. A cutting disc is fixedly connected to the end of the first motor near the transmission belt via a coupling. The synchronous belt allows the first rollers to rotate.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model employs a technical solution that uses two transmission belts to move the die-casting parts, ensuring that multiple die-casting parts can be continuously trimmed. This effectively solves the problem that usually only one die-casting part can be trimmed, leading to frequent replacements during trimming and reduced production efficiency, especially in mass production where the mold's potential cannot be fully utilized. Transmission belts are installed on the surfaces of both first rollers, with the other ends of each belt supported by a first roller. When one first roller rotates, both transmission belts rotate, thus moving the die-casting parts. Limiting plates are installed on the surfaces of both transmission belts, with each pair of plates continuously positioned to constrain the die-casting parts. Multiple second rollers are also installed inside the two transmission belts, maintaining close contact with them to ensure that the die-casting parts do not loosen during trimming.

[0019] Preferably, the rotating mechanism includes four first rollers 201, which are rotatably connected to one side of the first U-shaped plate 101 and the second U-shaped plate 105, respectively. The first rollers 201 are arranged in pairs, and two transmission belts 2 are respectively sleeved on the surfaces of the two sets of first rollers 201. Each set of first rollers 201 has a rotating mechanism on one side for rotating the first rollers 201. The transmission belts 2 can be rotated by the arrangement of the first rollers 201.

[0020] Furthermore, the rotating mechanism includes a first synchronous pulley 205, which is fixedly connected to one end of one of the first rollers 201. A second motor 208 is fixedly connected to the surface of the base 1 and the second U-shaped plate 105 near the first synchronous pulley 205.

Transmission belts 2 are installed on the surface of both first rollers 201, and the other ends of both transmission belts 2 are also supported by the first rollers 201. Thus, when one of the first rollers 201 rotates, both transmission belts 2 will rotate, thereby driving the die-cast part to move.

Multiple second rollers 202 are also installed inside the two conveyor belts 2, and the multiple second rollers 202 are in close contact with the conveyor belts 2 to ensure that the die casting will not loosen during the edge cutting process. An extrusion plate 204 is installed on one side of the conveyor belt 2, and both ends of the extrusion plate 204 are inclined. When the die casting comes into contact with the extrusion plate 204, the die casting will move according to the shape of the extrusion plate 204 to ensure that it can be cut normally.
