Technical field
The utility model is related to a kind of polyurethane injecting paste material specimen molding molds.
Background technology
Injecting paste material type is various, should have extensively.Over nearly more than 30 years, organic chemistry injecting paste material is quickly grown, polyurethane
The one kind of class injecting paste material as organic chemistry slurries, with its good property noted, cohesiveness, outstanding water blockoff and anti-permeability performance
Widely is studied and applied by domestic and foreign scholars.In the research to polyurethane sludge injection material, the examination for preparing small size is needed
Part is used for experimental study.Existing test material preparation mold majority is the cavity of the metal tube composition spirally covered with there are two,
Since polyurethane material has certain caking property, dilatancy, at the same the reflection of individual species material is very fast, the reaction time compared with
Short, these features can lead to the problem of all kinds of in test material preparation, be concentrated mainly on that mould impermeability is poor, in specimen molding rear mold
Lower sealing cover can not unscrew.For example, since material has stickiness and dilatancy, while itself permeability is stronger, in mold
It after capping is tightened, often has and is oozed out at the gaps a certain amount of slurries Gai Kou, connect along with slurries cohere completely with capping top
It touches so that capping is closely bonded together with metal tube, slurries, can not be unscrewed；Other part material reflecting time comparatively fast also can
Slurries have reacted expansion and overflow mold in causing to manage when capping is not yet tightened, and model is made to prepare failure, influence to test into
Journey.
