Description

Technical Field

[0001] This utility model belongs to the field of die casting technology, and more specifically, relates to a trimming device for aluminum die casting products. Background Technology

[0002] After a die-cast part is removed from the die-casting machine, it must undergo a cleaning process. This cleaning process includes removing the gating system, overflow system (overflow groove / slag collection bag, etc.), venting system (vacuum venting groove, etc.), excess material (material handle), burrs, etc., which are collectively referred to as trimming.

[0003] Typically, after die castings are removed, excess material is manually knocked away to trim the edges. However, manual trimming is inefficient for mass production of die castings. For thin-walled die castings, manual trimming easily leads to hammering deformation and chipping, making it difficult to guarantee casting quality. Furthermore, larger thin-walled die castings often have complex gating, overflow, and venting systems, making manual trimming a very heavy and tedious manual labor task, resulting in low efficiency and high labor costs.

[0004] The existing patent authorization announcement number: CN220880701U, discloses a trimming mold for aluminum die-casting products, including an upper plate and a lower plate, both of which have notches for fixing. The key feature is that a lower mold base is fixed in the middle of the lower plate, and a lower mold is fixed on the lower mold base. A pressure sleeve structure is installed in the middle of the upper plate, and a cutter is also fixed to the upper plate surrounding the pressure sleeve structure. The pressure sleeve structure, cutter, and lower mold base are respectively arranged on opposite sides of the upper and lower plates, and the upper and lower plates are guided by guide posts. The pressure sleeve structure consists of a spring and a pressure mold; one end of the spring is fixed to the upper plate, and the other end is connected to the pressure mold. The surface of the pressure mold is adapted to the product shape. The cutter consists of a columnar cutter holder and a cutting edge at the top of the cutter holder. The inner wall of the cutter holder is adapted to the product shape. The cutter consists of two to six sets of small cutters, each independently fixed to the surface of the upper plate and surrounding the pressure sleeve structure. The guide post consists of a guide rod fixed to the upper plate and a guide sleeve fixed to the lower plate.

[0005] However, existing technologies have the following drawbacks: when the cutting die is cutting, the position of the die casting is easily changed, and the die casting cannot be placed on the template accurately and quickly, which easily leads to inaccurate cutting, increases the product defect rate, reduces product productivity, and is not very convenient to operate, which is time-consuming and labor-intensive.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
