Abstract
The invention relates to a hard plastic co-extrusion method, using two extrusion machines with soft hard plastic on a streamline to extrude to one mold to make it melt inside the mold, controlling the hard plastic in 175deg.C-185deg.C and the soft plastic in 155deg.C-165deg.C, extracting the air from the mold on the vacuum cooling working platform, allowing the plastic part sticking close to the mold cavity to get away the heat, cooling and shaping the product, with the plastic part close to the mold cavity tightly and converting from fuse state to glass state, using extractor to drag the shaping mold in the power of 2-5kw, extraction force hundreds of thousands N, the extruded part being cut synchronically by the cutter, using one mold to stick the soft and hard plastic directly, reducing secondary processing, labor cost and material cost.
Description
Technical field
The present invention relates to a kind of soft and hard plastic co-extrusion method.
Background technology
The framework that uses under occasions such as plastic window door, icebox in order to play sealing, choke, insulation effect, needs soft section bar and is combined with each other.
Generally be prefabricated groove in the gravity die material in the prior art, allow soft material the soft or hard section bar be lumped together in being inlaid into.But producing this product needed has two section bar streamlines to finish:
The gravity die material will be made up of streamlines of machine such as extruder, hard timber die, vacuum cooled workbench, hauling machine, cutting machines, finishes production and processing;
Soft section bar also is to need an above-mentioned streamline to form, and finishes production and processing;
Then soft section bar is embedded and form the requirement that a soft or hard section bar reaches use in the gravity die material.
The problem of the existence of this method also is conspicuous:
The first, take two streamlines and finish, the mould that the Second Mate is different is finished this soft or hard section bar;
The second, need secondary operations that soft section bar is inlaid into the gravity die material.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of soft and hard plastic co-extrusion method, are intended to solve above-mentioned defective.
In order to solve the problems of the technologies described above, the present invention realizes by following steps:
On a streamline, adopt two extruders to add soft and hard plastic respectively;
Clamp-on simultaneously in one pair of mould, make it bonding in mould when high temperature; Hard material is controlled at 175 ℃-185 ℃, and soft material is controlled at 155 ℃-165 ℃;
On the vacuum cooled workbench, extract air in the mould, make plastic be close to die cavity wall, take away heat; Cooling water flows in stock mould and makes the mould temperature descend the product cooling and shaping simultaneously;
Plastic is close to cooling and shaping mould die wall and is transformed to glassy state by molten state, with hauling machine it is pulled out in stock mould; The hauling machine motor power (output) is about 2～5 kilowatts, and its tractive force is about thousand Ns of hundreds ofs;
This plastic extrude length by the cutting machine synchronous cutting, according to length requirement by the up and down scale cutting of garden saw blade.
Compared with prior art, the invention has the beneficial effects as follows: machine takies minimizing, cuts down the consumption of energy; Only need to adopt one pair of mould, reduced die cost; The soft or hard material is directly bonding, reduces secondary operations, reduces cost of labor; The soft or hard material is directly bonding, and it is simple to make it profile shapes, reduces material cost.
