Problems solved by technology

[0003] The problem with these two traditional demoulding methods is: brushing the mold release agent will pollute the surface of the molded material, so it is necessary to remove the mold release agent from the surface of the molded material after demoulding, so as not to affect its application and performance, thereby increasing the process and causing waste
Therefore, the yield rate of the buoyant material formed by the existing demoulding method is low, and it is neither economical nor environmentally friendly.

Abstract

The invention relates to an environment-friendly easily-demolded compression molding device, which comprises an outer mold 1, an assembled polytetrafluoroethylene inner lining 2, an upper cover 3, a lower cover 4, an upper sealing fin 5 and a lower sealing fin 6. The compression molding device is simple and practical in structure, and is convenient to disassemble and assemble; the surface of a molding material is not polluted, the molding material can be used repeatedly, demolding is very smooth, the molding material is smooth and flat on the surface and does not need secondary machining, machining procedures are reduced, and the aims of simplifying demolding post-treatment and improving the economic efficiency and environmental friendliness are fulfilled. When the device is applied to molding equipment for buoyancy materials, the problems of low yield, poor economic efficiency and environmental pollution existing in a buoyancy material molded by using the conventional demolding method are solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of mechanical manufacturing. More specifically, the present invention relates to an environment-friendly easy-release molding device and its application in the preparation of buoyant materials. 【Background technique】 [0002] In the process of material compression molding, in order to facilitate demoulding, it is usually used to assist demoulding by brushing a release agent on the inner surface of the mold or pasting a release paper. [0003] The problem with these two traditional demoulding methods is that applying the release agent will pollute the surface of the molded material, so it is necessary to remove the release agent from the surface of the molded material after demoulding, so as not to affect its application and performance, thereby increasing the process and causing waste. When using the method of pasting the release paper to release the mold, the release paper needs to be cut into a suitabl...
