Description

Technical Field

[0001] This utility model relates to the field of edge trimming technology for die castings, and in particular to an edge trimming mold for aluminum die castings. Background Technology

[0002] A casting trimming die is a tool or device specifically used to remove excess edges from die-cast parts. During the die-casting process, as molten metal fills the mold cavity and cools and solidifies, it forms a die-cast part with excess parts such as flash, burrs, and gates. These excess parts are usually not part of the final product's design requirements and need to be removed using a trimming die to obtain a die-cast part that meets the precision and appearance requirements.

[0003] Chinese Patent Publication No. CN220920879U discloses a cutting device for aluminum die-casting molds with good fixing effect, including a cabinet. A clamping mechanism is installed on the top of the cabinet. The clamping mechanism includes a base, and a cylinder is arranged on the right side of the top of the base. The output end of the cylinder is rotatably connected to a pressing plate. This cutting device can perform cutting operations on workpieces of various specifications through the clamping mechanism. After the die-casting workpiece is firmly clamped by the pressing plate and the placement seat, the geared motor is turned on. Since the top of the pressing plate is rotatably connected to the output end of the cylinder, the clamped workpiece can be made to rotate. The servo motor drives the moving table to move linearly to the left through the lead screw, and drives the grinding disc to rotate through the output end of the drive motor to perform the cutting operation on the workpiece. Through the combination of the above technologies, cutting operations on die-casting machines of various specifications can be realized.

[0004] However, the above technical solution has the following shortcomings: When the edge trimming equipment drives the grinding disc to trim the edge through the drive motor, the position of the drive motor is fixed on the protective frame and remains stationary. As a result, the grinding disc can only trim the part that is in contact with the rotating surface of the grinding disc. If the size of the workpiece is large, it is necessary to continuously adjust the position of the workpiece on the placement seat for edge trimming. The operation is troublesome and not conducive to use. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an edge trimming die for aluminum die castings. This die solves the problem that when the workpiece size is too large, the grinding disc cannot easily process various parts of the workpiece surface to be processed, thereby improving the efficiency of edge trimming.

[0006] The technical solution of this utility model is an aluminum die-casting trimming mold, including a base and a driving mechanism. A placement platform and a mounting seat are provided on the top of the base. A first motor is provided on the mounting seat, and a grinding disc is driven and connected to the first motor. The driving mechanism includes two symmetrically distributed and slidably arranged blocks on the base, a lifting component on the blocks, and a translation component on the lifting component.

The left lifting block is threadedly connected to the first threaded rod, the right lifting block is slidably connected to the first fixed rod, and the first threaded rod is rotatably connected to the left fixed block.

[0009] Preferably, the stop block is provided with a connecting block and a connecting plate, and the base is provided with two first cylinders distributed on the left and right, and the first cylinders are driven to connect with the connecting block.

[0010] Preferably, a rotating column is coaxially arranged on the placement platform, the rotating column is rotatably connected to the base, and the base is provided with a rotating component that drives the rotating column to rotate.

[0011] Preferably, the rotating assembly includes a fourth motor disposed inside the base, a second gear driven and connected to the fourth motor, and a first gear coaxially disposed on the rotating column, wherein the first gear meshes with the second gear.

The lifting assembly includes four fixed blocks 7 distributed on the blocks 6, a second motor 8 mounted on one of the fixed blocks 7, a first threaded rod 9 drivenly connected to the second motor 8, two left and right distributed lifting blocks 11, and a first fixed rod 10 mounted on the right fixed block 7. The left lifting block 11 is threadedly connected to the first threaded rod 9, and the right lifting block 11 is slidably connected to the first fixed rod 10. The first threaded rod 9 is rotatably connected to the left fixed block 7. A guide block 17 is provided on the lifting block 11, and a groove is provided on the blocks 6 for the guide block 17 to slide vertically.

[0024] The translation component includes a third motor 12 mounted on the left lifting block 11, a second threaded rod 13 rotatably mounted on the lifting block 11, and a second fixed rod 14 mounted on the lifting block 11. The mounting base 3 is threadedly connected to the second threaded rod 13, and the mounting base 3 is slidably connected to the second fixed rod 14.

[0025] In this embodiment, the driving mechanism enables the grinding disc to process various parts of the workpiece surface, improving the practicality of the equipment. The second motor 8 drives the first threaded rod 9 to rotate. Guided by the first fixed rod 10 and guide block 17, the first threaded rod 9 engages with the lifting block 11. The first lifting block 11 drives the mounting base 3 to move vertically, thereby controlling the grinding disc 5 in the vertical direction. The third motor 12 drives the second threaded rod 13 to rotate. Guided by the second fixed rod 14, the second threaded rod 13 engages with the mounting base 3. The mounting base 3 moves horizontally along the axial direction of the second threaded rod 13, thereby controlling the grinding disc 5 in the horizontal direction.

[0026] Example 2

[0027] like Figure 1 and Figure 2 As shown in the figure, the aluminum die casting trimming mold proposed in this embodiment has a connecting block 15 and a connecting plate 27 on the stop block 6 compared to the first embodiment. The base 1 has two first cylinders 16 distributed on the left and right. The first cylinders 16 are driven to connect with the connecting block 15. The connecting plate 27 is used to connect the two stop blocks 6.

[0028] In this embodiment, the connecting block 15 is driven to move horizontally by the first cylinder 16. The connecting block 15 drives the stop block 6 and the grinding disc 5 to move toward the workpiece so as to perform edge trimming on the workpiece. At the same time, the stop block 6 can prevent waste material from splashing to both sides during edge trimming.

[0029] Example 3

[0030] like Figure 1 and Figure 4 As shown, in this embodiment, an aluminum die-casting trimming mold is proposed. Compared with the first embodiment, in this embodiment, a rotating column 18 is coaxially arranged on the placement platform 2. The rotating column 18 is rotatably connected to the base 1.

[0032] like Figure 4 As shown, the placement platform 2 is provided with four rollers 22 arranged in a ring array, and the base 1 is provided with a circular groove for the rollers 22 to roll. The rollers 22 are used to reduce the friction between the placement platform 2 and the base 1 and reduce energy consumption.

[0033] In this embodiment, when it is necessary to fix the workpiece, the surface to be processed is first oriented towards the grinding disc 5, and then the second cylinder 24 is activated to drive the pressure plate 25 downward until the elastic anti-slip pad 26 is pressed tightly against the workpiece, thereby fixing the workpiece. When it is necessary to adjust the position of the workpiece to perform edge trimming on different surfaces, the second cylinder 24 is first used to drive the pressure plate 25 upward, and then the fourth motor 20 is activated to drive the first gear 19 and the second gear 21 to mesh and transmit power, thereby rotating the column 18 to drive the placement table 2 to rotate, thereby adjusting the position of the workpiece, which has good practicality.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
