Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 4, the utility model provides a reusable composite material casting mold, which comprises a bottom plate 1 and an outer mold connected to the top of the bottom plate 1, wherein a detachable inner mold 4 is arranged in the outer mold. The internal mold 4 comprises an internal mold core 8 and a silica gel outer layer 5 wrapped outside the internal mold core 8, the internal mold core 8 is made of a wood material, the silica gel outer layer 5 is made of a silica gel material, the silica gel outer layer 5 is assembled and used together during casting, fine lines on the surface of a product can be clearly sketched out by the silica gel outer layer 5, fine features on a prototype part can be well reproduced, and the internal mold has excellent simulation performance and extremely low shrinkage rate, basically does not lose the dimensional accuracy of the product, has the characteristics of good demolding performance, difficult deformation, high temperature resistance, acid and alkali resistance and no expansion, and is suitable for long-term repeated use. The bottom plate 1 is connected with a positioning middle plate 6 for positioning the outer die and the inner die 4, plays a role in positioning the outer die and the inner die 4 through the positioning middle plate 6, can be convenient to assemble, and increases the precision of die assembly.

The outer die comprises two side plates I2 and two side surfaces II 3, the side plates I2 and the side surfaces II 3 are detachably connected, and the side plates I2 and the side surfaces II 3 are inserted in the outer side of the positioning middle plate 6.
