Flashing prefabricated part and forming die thereof

The flashing prefabricated part comprises a body and further comprises a clamping strip and a clamping groove, the clamping strip is vertically arranged and fixedly arranged on one side of the body in the length direction, and the clamping groove is formed in the side, away from the clamping strip, of the body and extends to the top and the bottom of the body. The shape of the clamping grooves is matched with the shape of the clamping strips, and two adjacent bodies are inserted into the clamping grooves in a matched mode through the clamping strips during installation. The method has the advantages that the possibility of dislocation between the flashing prefabricated parts is reduced, and therefore the effect of follow-up waterproof operation and the effect of attractive appearance are guaranteed. 本申请涉一种泛水预制件及其成型模具，其包括本体，还包括卡条及卡槽，所述卡条竖直设置、并固定设置于所述本体长度方向一侧，所述卡槽开设于所述本体远离所述卡条的一侧、且延伸至所述本体的顶部及底部，所述卡槽的形状与所述卡条的形状相适应设置，安装时相邻的两所述本体通过所述卡条插接配合于所述卡槽。本申请具有降低泛水预制件间发生错位的可能，从而保证后续防水作业的效果及外形美观的效果。
