Problems solved by technology

[0008] Die casting casting is a method of applying pressure to molten metal and injecting it. It is a casting method that can manufacture a large number of products in a short time. However, when the cycle is shortened to improve productivity, the temperature of the mold will increase. For the release agent of Patent Document 1, there is a problem. The problem of reduced mold release

Embodiment 1～7、 comparative example 1

[0089] (Preparation of oily release agent composition)

[0090] The oil-based release agent composition described in Examples 1-7 and Comparative Example 1 was prepared with the composition (mass %) shown in Table 1. The release properties at 350°C and 400°C were evaluated for each oil-based release agent composition. The evaluation method of the releasability will be described later.

Abstract

The present invention provides: a mold release agent composition which is configured to contain a polymer ester, and which is thus capable of exhibiting good mold releasability even in cases where thetemperature of a mold is increased; and a die casting method which uses this composition.

Description

technical field [0001] The present application relates to a release agent composition and a die casting method. Background technique [0002] In die casting, in order to lubricate the cavity in the mold, a release agent is sprayed after the mold is opened to form an oil film on the surface of the cavity, thereby preventing the cavity from being damaged by molten non-ferrous metals such as aluminum, magnesium, and zinc. Welding makes continuous casting possible. The mold release agents for die casting are roughly classified into oil-based mold release agents and water-soluble mold release agents. Recently, water-soluble mold release agents are widely used from the viewpoints of productivity, safety, and work environment. In addition, since oil-based mold release agents have high lubricity, their uses are limited, and they are used in fields requiring high lubricity. [0003] An oil-based release agent has a high viscosity and tends to be poor in sprayability, but Patent Doc...
