Description
Technical field
The present invention relates to the technical field of mould, the present invention relates to a kind of casting resin eyeglass mould in particular.
Background technology
Due to lightweight, refractive index is high and resistance to impact, present most of spectacle lens made of resin is all by resin manufacture.In order to make resin lens, usually adopt two half modules, they are commonly referred to as front mould and rear mold.When with Making mold resin lens, front mould and rear mold tight closure form a die cavity, and then resin melt are introduced in closed die cavity from sprue gate and make eyeglass.
At present, usually adopt top pouring to pour into a mould molten resin in prior art when molded ophthalmic lenses: its implication refers to and utilizes the mould with molding cavity to be vertically positioned, make sprue gate be positioned at die top, the filling device be connected with molten resin accumulator sends molten resin into molding cavity by sprue gate.In the fabrication process, discharge duct is also played in sprue gate.Inevitably, some bubbles produced in casting process are easy to be captured in sprue gate place, can form the vent plug of the casting process that slows down.And the vent plug formed can cause the inhomogeneities of cast, thus the possibility producing optical defect in obtained eyeglass is increased.
Summary of the invention
In order to solve the above-mentioned technical problem existed in prior art, the object of the present invention is to provide a kind of mould for casting resin eyeglass of novelty.
In order to solve the problems of the technologies described above and realize above-mentioned purpose, the invention provides following technical scheme:
A kind of spectacle lens made of resin mould, comprises the front mould with inner concave, the rear mold with outer convex surface, and is positioned at described front mould and rear mold and by described front mould and the sealed mould housing of rear mold, described front mould, rear mold and mould housing collectively define cast chamber; Described mould housing comprises the main body of cylinder socket, and is positioned at the upper end body of described main body the top and is positioned at described main body lower end body bottom; Described upper end body has the exhaust outlet be communicated with described cast chamber topmost, and described lower end body has the sprue gate be communicated with bottom with described cast chamber.
Wherein, described mould housing has the groove extending to the top, described sprue gate from described exhaust outlet bottom on the inner surface in correspondence described cast chamber.
Wherein, described mould housing becomes spell shape by two block plates are bending.
Mould of the present invention can avoid spectacle lens made of resin to produce the defect of bubble in the inhomogeneities of cast and eyeglass.

Fig. 2 is the perspective structure schematic diagram of resin lens mould of the present invention;
Fig. 3 is the external overall structural representation of resin lens mould of the present invention.
Detailed description of the invention
As Figure 1-3, spectacle lens made of resin mould of the present invention, comprise the front mould 20A with inner concave, the rear mold 20B with outer convex surface, with be positioned at described front mould 20A and rear mold 20B and by described front mould and the sealed mould housing 10 of rear mold, described front mould 20A, rear mold 20B and mould housing 10 collectively defines cast chamber 30; Described mould housing 10 comprises the main body of cylinder socket, and is positioned at the upper end body 12 of described main body the top and is positioned at described main body lower end body 18 bottom; Described upper end body 12 has the exhaust outlet 14 be communicated with described cast chamber 30 topmost, described lower end body 18 has the sprue gate 16 be communicated with bottom with described cast chamber 30, and described mould housing 10 has the groove (not shown) extending to the top, described sprue gate 16 from described exhaust outlet 14 bottom on the inner surface in correspondence described cast chamber 30.Wherein, described mould housing is become spell shape by two pieces of No. 40 steel steel plate bendings.Described No. 40 steel are through forging molding, and forging temperature is 800 DEG C.After forging molding, at N
2carry out temper in atmosphere, described temper comprises: first constant temperature process 60 minutes at 700 DEG C, after being then cooled to room temperature, is heated to 350 DEG C, temper 60 minutes.Improve processability and the elastic deformability of material after temper, thus be suitable for cold roll forming and form mould housing of the present invention.In addition, groove due to front mould rear end face, rear mold front end face and the mould housing inner surface described in described spectacle lens made of resin mould needs stand molten resin constantly to corrode and temperature transition frequently, the contact surface causing described cast chamber to limit can wear and tear, thus can stick together with shaping glasses base substrate, cause the surface quality of glasses blank to reduce.Front mould rear end face for this reason described in the present embodiment and the front end face of rear mold are coated with protective coating, described groove is formed with lubricant coating.Wherein, described protective coating is formed by cold spraying protective coating, and thickness is 5-10mm; Described protective coating comprises: the ethanol of the ethyl acetate of the nickel powder of 32wt%, the polytetrafluoroethylene powder of 5wt%, 15wt%, the aluminium oxide particles of 27wt%, the polymethyl siloxane of 2wt% and surplus.After the above-mentioned wear-resistant paint of cold spraying, the coefficient of friction of described contact surface can reach 0.15-0.18; HRC hardness reaches 53-56; Thus give the good wearability of described contact surface and aggressivity.Wherein, described lubricant coating adopts brushes slip coating formation, and thickness is 1-3mm, and the coefficient of friction of described lubricant coating is 0.10-0.12.Described slip coating comprises: the water of the zirconium English powder of the flake graphite of 38wt%, the diatomite of 12wt%, 3wt%, the andalusite powder of 2wt%, the magnesium aluminate spinel of 2wt%, the polytetrafluoroethylene powder of 3wt% and surplus.Described protective coating and lubricant coating can resist the erosion of molten resin, and prevent adhesion, cause the quality of lens blank to reduce.Described protective coating and lubricant coating generally can use and reach one-year age, and need not repair, and drastically increase mold use life-span and service efficiency.
Although detailed description of the invention part is elaborated technical scheme of the present invention by detailed description of the invention, but those of ordinary skill is to be understood that and can without departing from the scope of the present disclosure, equivalent replacement or equivalent transformation form can be adopted to implement technical scheme of the present invention.As long as no the embodiment departing from invention essence, be all interpreted as having dropped within protection scope of the present invention.
