Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy die casting equipment, specifically to an aluminum alloy die casting edge trimming mold. Background Technology

[0002] Aluminum alloy die casting is a technology that uses aluminum alloy as raw material and high pressure casting process to produce precision metal parts. It has the characteristics of high finished product precision, high material utilization rate and adaptability to the forming of complex thin-walled parts. In the processing of aluminum alloy die casting, the edges of the aluminum alloy die casting need to be processed by edge trimming mold.

[0003] Currently, traditional trimming dies typically employ a single-layer punching method, meaning they can only remove slag deposits from one side of the product. However, with the increasing complexity of aluminum alloy die-casting parts, to ensure smooth product forming and improve die-casting yield, some complex products require a double-layer overflow slag design, resulting in slag deposits and flash on both the top and bottom sides. This means traditional single-layer trimming dies cannot handle this in a single pass, necessitating product flipping and secondary processing, thus reducing production efficiency, increasing labor costs, and potentially causing a decrease in trimming accuracy and affecting processing quality due to secondary positioning. Therefore, we propose a trimming die capable of simultaneously removing both the top and bottom slag deposits to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting mold for aluminum alloy die castings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting mold for aluminum alloy die castings, comprising a lower die cutting edge plate and an upper die cutting edge plate. The lower die cutting edge plate includes a lower die cutting edge and a lower mounting template. Multiple sets of the lower die cutting edges are evenly arranged on the top of the lower die cutting edge plate, and the lower mounting template is located below the lower die cutting edge plate.

[0029] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4 Both the lower die cutter plate 1 and the upper die cutter plate 2 have movable slots inside. The lower die cutter 101 is movably connected to the lower die cutter plate 1 through the movable slot, and the upper die cutter 201 is movably connected to the upper die cutter plate 2 through the movable slot. The lower die cutter 101 and the upper die cutter 201 can be adjusted to facilitate trimming of the die casting. Both ends of the bottom of the lower die cutter plate 1 are provided with connecting blocks, and the bottom ends of the two sets of connecting blocks are connected to the lower template 102 by bolts to connect the upper die cutter... The upper die cutter plate 1 is fixed to the lower template 202. Fixing rods are provided at the four corners of the top of the upper die cutter plate 2, and the tops of the fixing rods are connected to the upper template 202 by bolts, thus fixing the upper die cutter plate 2 to the upper template 202.

[0030] Please refer to this carefully. Figure 1 and Figure 2 The bottom of the sleeve rod 3 is provided with a telescopic groove. The upright rod 302 is movably connected to the sleeve rod 3 through the telescopic groove. The sleeve rod 3 and the upright rod 302 can move up and down through the telescopic groove, which facilitates the adjustment and use of the cutting mold.

[0031] Working Principle: In use, when the upper and lower molds of the hydraulic press are closed, the force of the upper mold spring 205 is greater than that of the lower mold spring 105. The lower mold spring 105 will first compress the lower mold ejector plate 103. Through the connection between the lower mold ejector plate 103 and the lower mold cutting edge 101 via the positioning rod 104, the lower mold ejector plate 103 and the lower mold cutting edge 101 move synchronously. The lower mold cutting edge 101 works first to punch away the lower layer of slag from the product. The hydraulic press will then continue to move downwards. The upper mold stripper plate 203 can be connected to the upper mold cutting edge 201 via the connecting rod 204, allowing the upper mold stripper plate 203 and the upper mold cutting edge 201 to move synchronously. Through the action of the upper mold spring 205 and the hydraulic press, the upper mold cutting edge 201 will punch and remove the upper slag bale of the product, thereby achieving the function of removing the flash of two layers of slag bale at the same time. It can quickly perform edge trimming on aluminum alloy die castings, resulting in better processing effect and improved processing quality of aluminum alloy die castings.
