AI Technical Summary

Technical Problem

Traditional die-casting molds have problems such as high waste rate at the distal air hole defect, uneven growth force caused by product bias to one side, complex mold structure leads to waste of materials and increased costs, failure of overflow groove structure, lack of exhaust ducts, difficulty in mold matching of the integral type of the slider structure, difficulty in repairing the overall structure of the slider core, low strength of the moving mold frame, and inability to place the mold vertically independently.

Method used

A mold for die-casting of a bracket is designed, including a moving die frame and a fixed die frame, the movable die core cooperates with the recesses of the fixed die core to form a cavity, and an inner gate, runner, slider, exhaust channel and improved support structure, as well as a square die foot for independent vertical placement.

Benefits of technology

By optimizing the order of aluminum water filling, material saving and damage reduction, increasing exhaust ducts to improve product quality, strengthening mold strength, and improving mold placement methods, various problems of traditional molds have been solved, and production efficiency and product quality have been improved.

Abstract

The utility model relates to a die for bracket die casting, which comprises a movable die frame and a fixed die frame, a movable die core is arranged in the movable die frame, and a fixed die core is arranged in the fixed die frame; the opposite side faces of the movable mold core and the fixed mold core are each provided with a concave part corresponding to the support in shape. The concave parts of the movable mold core and the fixed mold core are matched to form a cavity. The cavity is connected with a flow gate arranged on the movable mold core, the flow gate is connected with the outflow end of a pouring gate arranged in the movable mold core, and the inflow end of the pouring gate is connected with a material cake; a sprue bush matched with the material cake is arranged on the fixed mold frame; and a boss is arranged in the cavity. According to the utility model, the two flow gates are arranged, so that the filling sequence of molten aluminum is optimized; due to the balance design of asymmetry and overall symmetry of all parts of the whole mold, materials are saved, and the damage probability is reduced; the sliding block is added, so that an exhaust passage can be formed, and the product quality is improved; a supporting structure is improved, and the mold strength is enhanced; the mold foot is changed into a square shape, so that the mold foot can be independently and vertically placed.
