Description
[technical field]
The invention belongs to machinery manufacturing technology field.More specifically, the present invention relates to a kind of compression molding device of the environment protection type easy demoulding and the application in buoyant material preparation thereof.
[background technology]
In material compression molding process, conveniently the demoulding is typically employed in mould inner surface brushing releasing agent or pastes the mode assisted demoulding of processing release paper.
These two kinds traditional release method Problems existing are: brushing releasing agent can pollute compression molded material surface, therefore the Transformatin after demoulding material surface of compression molding being carried out to releasing agent is needed, in order to avoid affect its application and performance, thus increase operation and cause waste.Adopt when pasting the method demoulding of processing release paper, then need processing release paper to be cut into suitable size and need smooth to be pasted onto mould inner surface, whole process is loaded down with trivial details and efficiency is low.
Especially for low-density, high strength buoyant material, himself require usually therefore to cause the breakage of moulding material during the conventional method demoulding by the adhesive property that high strength is namely excellent.In addition, need to apply certain pressure to mould because buoyant material is shaping, this often causes processing release paper to be out of shape thus affects the configuration of surface of buoyant material, sometimes even causes processing release paper to break and makes the excessive difficulty finally causing the demoulding of raw material.And releasing agent and processing release paper are all single use.Therefore, the shaping buoyant material yields of existing release method is low, and not only uneconomical but also not environmentally.
For this reason, the present inventor, on the basis of summing up prior art, is worked by lot of experiments, finally completes the present invention.
