Giving architects and sculptures free imagination and space to create.

In the prior art, two common preparation modes of polyurethane rubber mold, namely rubber mold for short, are as follows when precast by adopting a concrete decoration molding process:

mode a: directly bonding the rubber mold with decorative modeling with a steel mold by using a matched adhesive;

mode B: firstly, bonding a rubber mold on a wood mold serving as a supporting structure, and then fixing the wood mold on a steel mold for reuse;

the two technical schemes often have the following problems in application:

1) For special-shaped components, particularly modeling components with bevel edges, the adhesive cannot be fully covered and spread on the steel mould, so that the final mould has poor bonding effect and seriously affects subsequent work.

2) Splice welds and irregularities on the steel form are significantly reflected on the glue film, degrading the quality of the final molded product.

3) Professional field bonding must be added, the operation procedure is time-consuming and inefficient, and the operation efficiency is not high.

4) After the molding work is finished, the rubber mold is not required to be stored independently in a short time, however, the operation process of stripping the rubber mold from the steel mold is very complicated, the rubber mold can be cut and separated slowly only by a hand-held art knife, the time is wasted, the efficiency is low, and the adhesive film is sometimes damaged. Furthermore, it is provided that;

5) The flatness of the wood pattern affects the flatness of the final effect surface.

6) The conventional wood form has no waterproof performance, and after the conventional wood form is used for prefabricating and producing cast concrete for many times, repeated seepage of cement paste can cause expansion deformation of the wood form.
