Description
[technical field]
The invention belongs to machinery manufacturing technology field.More specifically, the present invention relates to a kind of compression molding device and the application in buoyant material preparation thereof of the environment protection type easy demoulding.
[background technology]
In material compression molding process, for the mode assisted demoulding of conveniently stripped common employing at mould inner surface brushing releasing agent or stickup processing release paper.
The problem of these two kinds traditional release method existence is: brushing releasing agent can pollute compression molding material surface, therefore need to after the demoulding, to the material surface of compression molding, carry out the Transformatin of releasing agent, in order to avoid affect its application and performance, thereby increase operation and cause waste.While adopt pasting the method demoulding of processing release paper, need by processing release paper be cut into suitable size and needs smooth stick on mould inner surface, whole process is loaded down with trivial details and efficiency is low.
Especially for low-density, high strength buoyant material, himself requiring high strength is excellent adhesive property, usually therefore causes the breakage of moulding material during the conventional method demoulding.In addition, because buoyant material moulding need to apply certain pressure to mould, thereby this often causes processing release paper distortion to affect the configuration of surface of buoyant material, sometimes even causes processing release paper to break and makes the excessive difficulty that finally causes the demoulding of raw material.And releasing agent and processing release paper are all disposable use.Therefore, the buoyant material yields of existing release method moulding is low, and not only uneconomical but also not environmental protection.
For this reason, the inventor, summing up on the basis of prior art, works by lot of experiments, has finally completed the present invention.
