Description of the Invention: [Technical Field] The present invention relates to a molded glass lens having a plurality of grooves on a shoulder and a molding die thereof, and more particularly to an outer ring portion of a cavity of a molding die Three or more equal height protrusions arranged in a ring shape are arranged, so that in the mold forming process, the air in the cavity can be evacuated from the gap formed by the height difference around the protrusions after being evacuated by the molding apparatus. A good venting effect is achieved; and the molded glass lens manufactured by the plastic mold can form opposite grooves on the shoulder of the lens by the convex body without affecting the assembly of the 0 lens. [Prior Art] Press, precision molding molding technology has been widely used to manufacture aspherical molded glass lenses with high resolution, good stability and low cost, such as US2006/0107695, US2007/0043463 'TW095101830 > JP63-295448, TW095133807, etc., which use a glass to soften at a high temperature, heat and soften a glass preform in the upper and lower molds, and then close and press the upper and lower molds. (And before the molding, the molding equipment will first vacuum), the optical surface of the upper and lower mold cores are transferred to the softened glass preform, and after cooling, the upper and lower mold cores are separated and become an upper and lower mold. The molded glass lens of the curved surface; wherein the glass preform has a spherical shape, a drop shape, a flat plate shape, and a blank material which is firstly ground to form a shape close to the shape of the molded lens. According to the above process of molding the glass lens, the glass preform is in close contact with the upper and lower molds, and during the heating and pressurization process, the glass preform is forced to press the upper and lower mold cores, and the mold core has A little residual air will form bubbles on the surface of the lens and affect the forming quality of the cymbal; especially the glass pre-molding system is placed on the lower mold, although the molding equipment will first vacuum before molding. But 3 200900364 The air in the mold cavity It cannot be ruled out due to the influence of glass preform weight force; the prior art has the following methods to try to solve the problem of residual air: <1>, using the method of controlling pressure, temperature or surface roughness: such as JP2002-003225, JP05-286730, JP06-191861, US 20050172671, EP0648712, etc. 'When the material purity variation or shape and size of the glass preform change, the operating conditions will also change, so that simply controlling the operating conditions does not completely solve the residual air. The problem. <2>, an air passage is provided in the molding apparatus so that the gas can be discharged from the passage during the warming and pressurization process, such as jP6i-291424, TWI248919'JP2000-044260'TW200640807'US20050242454, etc. For spherical or drop-shaped glass preforms, the air passages have better exhausting effects; however, for flat or disc-shaped glass preforms, flat or disc-shaped preforms may be used. Pressing the exhaust passage, or the glass preform may block the gas passage when heated and soften, reducing the exhaust effect. < 3 >, on the mold core (especially the lower mold core) is provided with grooves or vents, etc.: such as JP61-291424, JP08-337428, US7, 159, 420, etc., but such grooves or vents may The opposite Q bumps are formed on the formed lens, which causes problems in secondary processing or subsequent assembly. However, if the bump on the lens is to be reduced, the grooves and vent holes on the mold core are smaller and relatively generated. Poor exhaust problem. The exhaust effect is generally expressed in terms of exhaust efficiency, which is equal to the cross-sectional area of the exhaust passage divided by the cavity volume ((5 = cross-sectional area of the exhaust passage / cavity volume); when exhaust efficiency 3 The larger, the air can escape quickly during the molding process without accumulating, and the exhaust efficiency (5 low, indicating that the exhaust is easy to block; through long-term experimental results, for flat or disc-shaped glass preforms, (5 value should be greater than 1 or more. In the conventional technique of providing an exhaust passage in a molding apparatus, if the passage cross-sectional area is large enough, it can approach 4 200900364 (5=0.25, but there will be a large amount of molten glass at this time) Will infiltrate into the channel to form a skirt, which will require secondary processing to remove the edge after forming; and in the conventional technique in which the lower mold has a plurality of grooves to form a venting passage, the glass preform can be prevented from being pressed. The air passage blocks the exhaust, but a certain number of bumps are formed on the molded lens, which will cause difficulty in assembling the lens, and if the groove has a small cross section, the d value is too low and the exhaust effect is lacking. And will not form on the lens The projections are designed to avoid the assembly of the lens or to affect the assembly of the lens in order to meet the yield and yield of the mass production. [The present invention] The main object of the present invention is to provide a number on the shoulder. a grooved molded glass lens, the molded glass lens comprising upper and lower optical surfaces and upper and lower shoulder portions on the outer periphery of each optical surface, characterized in that: three on the lower shoulder and/or the upper shoulder Or the groove arranged in a ring shape, but does not affect the original size of the shoulder, and can avoid the influence of the groove for the exhaust in the conventional molded glass lens forming mold on the shoulder of the lens. The size and precision of the shoulder of the lens are used to improve the molding yield of the molded glass lens without affecting the subsequent assembly work of the lens, so that the production of the lens meets the demand for mass production and yield. The object is to provide a molded glass lens having a plurality of grooves on the shoulder, wherein the shapes of the plurality of grooves provided on the shoulder of the lens are not limited, and one of the grooves may have a shape different from the other grooves. The lens has a discriminating function 'helping the alignment function of the lens or the correcting operation of the molding die. Another object of the present invention is to provide a molded glass lens into a mold of 200900364, which comprises upper and lower mold cores. The mold cavity of each mold core includes a central portion for molding the optical surface of the lens and a ring portion for forming the outer shoulder of the lens, and the upper and lower molds are correspondingly closed and pressurized to be placed in the cavity. The glass pre-form phantom is a type of glass lens, characterized in that: the lower mold core and/or the outer mold core cavity are provided with three or more convex bodies of equal height arranged in a ring shape, so that the mold is formed. During the process, the air in the cavity is evacuated from the gap formed by the height difference around the convex body by the vacuuming of the molding device, thereby achieving a high efficiency exhaust effect; and the convex body can be on the shoulder of the lens The opposite groove is formed on the portion, so as to avoid the trouble that the groove for the exhaust in the conventional molding die relatively affects the size and precision of the groove on the shoulder of the lens caused by the formation of the phase f on the shoulder of the lens, and increase The molding yield of the in-mold glazing lens does not affect the subsequent assembly work of the lens. Another object of the present invention is to provide a molding die for molding a glass lens, the molding die having a convex body with respect to the shoulder of the molded glass lens, wherein the shape of the convex body is not limited, but the shape thereof is such that the molded glass after molding The lens can be demolded from the convex body, thereby simplifying the demolding operation of the molded glass lens without affecting the original size of the shoulder of the lens. Another object of the present invention is to provide a mold for molding a glass lens, wherein the three or more convex systems are evenly arranged around the circumference of the mold cavity, so that the cavity is formed. The medium air is quickly discharged from the gap formed by the height difference of the convex body by the vacuuming of the molding device, thereby improving the exhaust effect.
