Horizontal-type cold pressing chamber aluminum alloy die-casting die

Abstract

The invention discloses an aluminum alloy die-casting mold for a horizontal cold-press chamber. The aluminum alloy die-casting mold of the horizontal cold press chamber has a rare earth permanent magnet fixing device and a circulating water cooling system. The aluminum alloy body and the circular sheet-shaped iron insert are formed by die-casting at one time, which improves production efficiency and qualification rate, and reduces manufacturing costs. and energy consumption, the aluminum alloy body and the circular lamellar iron insert are closely combined, and there will be no quality problems such as separation or cracking, which improves the production of aluminum alloy die-casting parts with large direct circular lamellar iron inserts Efficiency and product quality, reducing product scrap rate, manufacturing costs and energy consumption.

Description

technical field [0001] The invention relates to a die-casting mold, in particular to a horizontal cold-press chamber aluminum alloy die-casting mold. Background technique [0002] The traditional horizontal cold chamber aluminum alloy die-casting mold is used for aluminum alloy die-casting parts with large-diameter circular flake-shaped iron inserts. Due to the large diameter and thin thickness of the inserts, it cannot be fixed and positioned during die-casting. The main body is pre-die-casted, and then the joint with the circular thin iron insert is machined to the matching size through machining, and then the circular thin insert is pressed into the bottom of the aluminum alloy body by a hydraulic press. [0003] There are following problems and shortcoming in above-mentioned technology: [0004] 1. The process route is long and the process is complicated. It needs to be completed through multiple processes such as die-casting, machining, and press-fitting, and the pro...

AI Technical Summary

Problems solved by technology

[0004] 1. The process route is long and the process is complicated. It needs to be completed through multiple processes such as die-casting, machining, and press-fitting, and the production efficiency is low.

[0005] 2. The effective matching area of ​​the joint between the aluminum alloy body and the iron sheet-shaped insert is small, which requires high machining accuracy, and the circular sheet-shaped iron insert is a stamping part, and its interference is difficult to guarantee, resulting in a high scrap rate high

[0006] 3. The bonding process of the aluminum alloy body and the iron sheet-shaped insert is mechanical crimping, and the mating area is small, so it is impossible to bond tightly, and quality problems such as separation or cracking are prone to occur under the influence of factors such as temperature changes or physical bumps
