Description

Technical Field

[0001] The utility model relates to the technical field of bionic high-adhesion-strength liquid crystal elastomer production, and more specifically, to a molding die for producing bionic high-adhesion-strength liquid crystal elastomer. Background Art

[0002] Bionic high-adhesion liquid crystal elastomer is a material that combines the principles of bionics and liquid crystal technology and has the characteristics of high adhesion strength and elasticity. Liquid crystal elastomer is a polymer material composed of liquid crystal molecules. Liquid crystal molecules have a special structure that can change their arrangement under different temperature and electric field conditions, thereby changing the performance of the material. Due to its wide range of uses, its plasticity process is very important. However, the traditional molding molds for the production of bionic high-adhesion liquid crystal elastomers still have some shortcomings. For example, traditional molds mostly allow the elastomer to cool naturally when demolding. This method is easily affected by the external environment, and in this process, the traditional device cannot effectively control the cooling rate of the elastomer, which will cause the elastomer temperature to be too high, resulting in demolding failure.

When the resistance wire is energized, it will generate a lot of heat. At this time, the heat is transferred to the air around it, and the surface of the mold is heated up by the second motor. With the above structure, the temperature of the elastic body during demoulding can be detected and controlled, so that it is kept in the optimal temperature range during the demoulding process, thereby avoiding the demoulding failure caused by excessive temperature.
