Description

Technical Field

[0001] The utility model relates to the technical field of mold tooling, in particular to a demoulding device for composite material molds. Background Art

[0002] The annular shell of the magnetic resonance imaging device is made of a composite material, which is a thermosetting composite material. The demoulding method is to manually use a crowbar or a wedge to demould the product from the mold body little by little after the mold is thermally cured. This demoulding method is time-consuming and labor-intensive. Although there are some devices at present, such as the Chinese utility model patent, application number 2023212856544, the patent name is a molding mold for thermosetting composite materials. In this patent, molding and demoulding are designed in one device, and the demoulding mechanism is provided on the demoulder, which is used to store the release agent stored in the storage box. Through the action of a high-pressure pump, it is transported to the liquid outlet of the demoulder for discharge, thereby facilitating manual demoulding. Although this structure sprays the release agent, it is mainly demoulding by manual labor, which is inefficient and easy to damage the mold product. Utility Model Content
