For realization aforementioned invention purpose, the technical solution adopted by the present invention includes:
The embodiment of the present invention provides a kind of process of civil LED convex lens comprising following steps: by poly-methyl methacrylate
Rouge is placed in special injection molding machine, and thawing processing is carried out under the conditions of 200-250 DEG C, later in 60-90 in the special die
It is independently formed under conditions of DEG C, forms the civil LED convex lens, the special die sets that there are two die cavitys.
Further, two die cavitys overlapping of the special die.
Further, dedicated melten gel cartridge module there are two being set in the special machine.
Further, the dedicated melten gel cartridge module of A and the dedicated melten gel cartridge module of B are equipped in the special machine, it is described special
Mold is equipped with A die cavity and B die cavity, and the dedicated melten gel cartridge module of the A is molded A die cavity, and the dedicated melten gel cartridge module of B is to B
Die cavity injection molding.
Further, the dedicated melten gel cartridge module of the A of the special machine is mounted on moving template.
Further, the dedicated melten gel cartridge module of the B of the special machine is mounted on moving template.
Compared with prior art, the invention has the advantages that the process of civil LED convex lens provided by the invention, is somebody's turn to do
Method uses special machine, in the machine of same model, only once plus one is penetrated platform, then special die, make production efficiency double (with
Compared using the product of multi-cavity mold), the production efficiency of civil LED convex lens is improved, civil LED convex lens can be widely used in
Field.
