Application technology of release agent for aluminum die casting die
(Summary description)Aluminum alloy die-casting, including aluminum, magnesium and zinc alloy series die-casting products, is widely used in automotive, telecommunications, motorcycles, home appliances and other industries. Mold release agent for aluminum alloy die casting is an auxiliary agent that must be used in the production process. Due to the different volume size, structure complexity and post-processing requirements of products, the requirements for release agent are also different. The zinc alloy material is heated and melted (aluminum melting point 660.4 ℃), injected into the mold cavity under high pressure in the liquid state, and the top part of the mold is opened for ejection in a short time. In order to ensure the smooth demoulding of products, the mold cavity surface must be sprayed with release agent before injection. The release agent for aluminum alloy die casting must meet the following requirements: 1. Oil. As an effective material for metal to metal isolation, organic silicone oil is an ideal choice. This silicone oil must have the characteristics of high temperature resistance and not affect the post-processing performance (such as aluminum product coating). 2. Water based. Because the mold is in a high temperature state, any solvent based release agent is not suitable. With water as the dispersion medium, the water evaporates rapidly in the high temperature environment, and the effective demoulding material is evenly distributed on the surface of the mold cavity. Uniform film formation, strong adhesion, high temperature erosion resistance, good demoulding performance. 3. Emulsion. Select appropriate emulsifier to emulsify silicone oil to prevent its carbonization at high temperature. To keep the surface of products and mold cavity clean. 4. No corrosion to castings and mold equipment. The wheel Gallery of casting products shall be clear, and the surface shall be smooth without trace, which will not affect the coating. Volatiles are smoke-free, non-toxic, do not pollute the environment and do not damage the health of operators.
