Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of die-casting metal parts production technology, and specifically to a die-casting metal parts trimming mold. Background Technology
[0002] In the production process of die-cast metal parts, trimming dies are key equipment used to remove excess parts from the edges of die-cast metal parts, such as flash and burrs. However, existing trimming dies for die-cast metal parts have many problems. For example, during the trimming process, insufficient positioning accuracy of the die leads to inaccurate trimming position of the metal part, resulting in large dimensional deviations in the trimmed product and affecting product quality. At the same time, existing trimming dies are prone to metal parts sticking to the die during demolding, which not only reduces production efficiency but may also damage the surface of the metal part, increasing the defect rate. In addition, traditional trimming dies have complex structures and high maintenance costs, making it difficult to meet the needs of large-scale, high-efficiency production.
[0003] Existing devices cut the metal film by stamping. This means that the cutter is only installed in one direction of the phone mold. As a result, the metal parts are not completely cut at the edges when cut by stamping, which can cause burrs or adhesion. Utility Model Content

A first lower cutter and a second lower cutter are provided on both sides of the placement plate. When a moving plate moves the mounting plate downwards, the second upper cutter and the second upper cutter on both sides of the moving plate cooperate with the first lower cutter and the second lower cutter to achieve a bidirectional extrusion trimming effect, effectively ensuring the quality of the trimmed edge. A first upper cutter and a third upper cutter are also fixedly installed at both ends of the mounting plate. The first upper cutter and the third upper cutter effectively cut both ends of the metal part. The bottom of the third upper cutter cooperates with the mating frame, effectively ensuring the quality of the trimmed edge. This invention solves the problems mentioned in the background art.
