Embodiment

[0021] An upper mold insert used for trimming of aluminum plates. The bottom of the upper mold insert 7 is provided with a connecting vertical edge 71, an arc connecting edge 72, a vertical hypotenuse 73, a vertical edge 74, and a horizontal hypotenuse 75 in sequence. , Horizontal edge 76 and connecting hypotenuse 77, such as figure 1 , 2 As shown, the connecting vertical side 71 and the connecting hypotenuse 77 are connected to the upper part of the upper mold insert 7, the connecting vertical side 71 and the vertical side 74 are parallel and in a vertical direction, and the horizontal side 76 is perpendicular to the vertical side 74, In addition, the horizontal side 76 is in the horizontal direction, and the inclination direction of the vertical hypotenuse 73 and the horizontal side 76 are located on the same side of the vertical side. Among them, the horizontal span between the vertical side 74 and the connecting vertical side 71 is 5 mm, the vertical span between the bottom ...

Abstract

The invention relates to an upper die insert and a die for aluminum plate trimming. A connecting vertical side, an arc-shaped connecting side, a vertical inclined side, a vertical side, a horizontal inclined side, a horizontal side and a connecting inclined side are sequentially arranged on the bottom part of the upper die insert; the connecting vertical side and the connecting inclined side are connected with the upper part of the upper die insert; the connecting vertical side and the vertical side are in parallel and are located in the vertical direction; the horizontal side is perpendicularto the vertical side and is located in the horizontal direction; the span of the horizontal inclined side in the horizontal direction is 1 to 3mm; the span of the horizontal inclined side in the vertical direction is 0.2 to 0.5mm; and a 2 to 5-degree angle is formed between the vertical inclined side and the vertical side. Compared with the prior art, according to the upper die insert and the diefor aluminum plate trimming provided by the invention, the aluminum skimming generation capacity is effectively reduced, and the mould cleaning and maintenance frequency is reduced.

Description

Technical field [0001] The invention relates to aluminum alloy plate processing, in particular to an upper mold insert and a mold for trimming the aluminum plate. Background technique [0002] With the rapid development of the automotive industry, the requirements for lightweight vehicles continue to increase. Aluminum alloy sheets began to be used in the production of automobile panels and structural parts. The aluminum alloy sheet produces aluminum chips during the trimming process, which seriously threatens the surface quality of the outer cover. In actual production, it is necessary to improve the finish of the trimming insert, reduce the probability of aluminum chips sticking to the edge of the insert, and increase the frequency of cleaning molds to reduce the impact of aluminum chips on the quality of parts. How to reduce the mold structure, or even eliminate the aluminum chips generated during the trimming of aluminum alloy materials, has become an important research top...
