[detailed description of the invention]
In order to make the purpose of the present invention, technical scheme and advantage are clearer, below in conjunction with accompanying drawing and embodiment, are further elaborated the present invention.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, trough plate mould 10 of the present invention includes a stress system 101, molding system 103 and Nei Mo underframe 109.Stress system 101 and molding system 103 are all built on interior mould underframe 109, constitute the agent structure of whole trough plate mould 10.Stress system 101 is in the periphery of whole mold system, and its inner bay is set as type system 103.Molding system 103 includes collapsible core 1033 and side form 1031, and collapsible core 1033 is positioned at the middle part of molding system 103, and its cross section is the open cavity of " arched door " shape, with supports support in cavity.Side form 1031 is installed in the both sides of molding system 103, forms a rectangular channel, and side form 1031 is bolted on interior mould underframe 109.
