Abstract

The invention discloses a mold for manufacturing a polarized lens. The mold comprises a rubber fixing ring, an upper glass mold and a lower glass mold. A circle of protruded strap with the upward radian is arranged on the inner side of the rubber fixing ring, and the thickness and the width of the protruded strap are uniform. Two thin-strap-shaped grooves which are centrosymmetric about the circle center of the rubber fixing ring are arranged in the middle of the protruded strap, and the length of each thin-strap-shaped groove corresponds to that of an arc edge of the polarized lens. Two small identified tiny bumps are respectively arranged at two ends of each thin-strap-shaped groove and correspond to the protruded strap. Due to the designed structure, the polarized lens can be accurately and simply fixed and centered in production, the quality of finished products is improved, and consumable and labor cost are reduced.

Description

A kind of making mould of polarized lenses

Technical field

The present invention relates to a kind of making mould of polarized lenses.

Background technology

Conventional at present polarized lenses all is a moulding by casting; And traditional polaroid implantation mode be with 6 on the bent substrate fixedly footing fix; This mode causes polaroid to wave up and down easily, is not fixed on the centre position of eyeglass, makes polarisation run look even loses the polarisation function.And traditional implantation mode, need artificial bending substrate in the production process, strengthened production cost and loss.

Summary of the invention

The object of the present invention is to provide a kind of making mould of polarized lenses, this mould is through special design structure, in the production of polarized lenses, can make during polaroid accurately and easily fixedly puts, thereby promote end product quality, reduction consumptive material and cost of labor.

For achieving the above object; The technical scheme that the present invention taked is: a kind of making mould of polarized lenses, comprise rubber retainer plate, upper glass mould and lower-glass mould, and it is characterized in that; There is protruding band the inboard of described rubber retainer plate; Described protruding band is a complete circle, and thickness and width are even, and have radian upwards.

There is faciola shape groove at described protruding band middle part, and described faciola shape groove is two, is symmetric points center symmetry with the center of circle of rubber retainer plate, is distributed in convexity and is with, and the arc limit partial-length of the length of every faciola shape groove and polaroid adapts.

Said convexity with on two corresponding positions of faciola shape groove on to be respectively arranged with the trickle convexity of three block identification property fast.

There is a handle in the outside of described rubber retainer plate.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the structural representation of rubber retainer plate.

The specific embodiment

Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the making mould of a kind of polarized lenses of the present invention.

As shown in Figure 1, a kind of making mould of polarized lenses comprises rubber retainer plate 1, upper glass mould 2, lower-glass mould 3, and the diameter of upper glass mould 2 and lower-glass mould 3 is identical with the internal diameter of rubber retainer plate 1.The middle inside of described rubber retainer plate 1 has circle thickness and a width even, and the convexity that has a radian is with 4.Convexity is the centrosymmetric faciola shape of a symmetric points groove 5 with two centers of circle with rubber retainer plate 1 being arranged on 4; The length of every faciola shape groove 5 is about 1/4th circular arcs of rubber retainer plate 1 (in actual production process; Should be as the criterion to adapt to the polaroid width, identical with polaroid arc limit partial-length).Mid point and the convexity above the end positions at every faciola shape groove 5 are with on 4 parts, and the trickle protruding block 6 of fritter sign property is all arranged.There is a square handle 7 in the outside of rubber retainer plate 1, is positioned on the symmetry axis of two faciola shape grooves 5.

When making polarized lenses; Earlier with six tabs 9 on the polaroid 8 arc limits; Corresponding described convexity embeds in two faciola shape grooves 5 with the position of the trickle protruding block 6 of six sign property on 4 simultaneously, makes polaroid 8 fixed-site; Again upper glass mould 2 is put into rubber retainer plate 1 from the top and be with 4 to offset until die edge and convexity, lower-glass mould 3 is put into rubber retainer plate 1 and is with 4 to offset until die edge and convexity from the below.Lower-glass mould 3 is because the frictional force of rubber retainer plate 1 inner surface reaches fixing effect.

The polarized lenses of being produced through the making mould of a kind of polarized lenses of the present invention; Because polaroid 8 position in process of production is accurately fixing; Therefore can not receive the influence of casting resin and take place to wave up and down; Polaroid 8 can not drawn close to monolateral, and when being cured heating for fixing shape, polaroid 8 is not easy to run look because of the inequality of being heated causes polarisation, the polarisation function of scattering and disappearing.In addition, adopt the fixedly mode of polaroid 8 of rubber retainer plate 1, do not need extra personnel to carry out the operation of traditional hand tabs fixation, simplified production procedure, reduced the influence of 8 pairs of eyeglass end product qualities of bending polaroid and the loss of raw materials for production simultaneously.
