Description of the Invention: [Technical Field] The present invention relates to a heating device for a molded glass device, and more particularly to a heating device for a molded glass device capable of controlling temperature distribution. [Prior Art] Uranium, digital cameras and portable electronic devices with digital camera functions are becoming more and more popular, and their requirements for image effects and thinness and shortness are becoming higher and higher. Conventional plastic lenses are more difficult to meet the high requirements due to the low light transmittance. Glass lenses - generally have two manufacturing methods, (4) grinding method and molding method, the grinding method is complicated by the processing process 'it is mainly applied to larger optical lenses, and the molding method produces lenses by injection and pressing mold technology' There is no need for a grinding process, which can overcome the shortcomings of glass lens grinding difficulties, so the molding method is becoming more and more popular. The manufacture of optical lenses disclosed in U.S. Patent No. 5,720,791, issued Feb. 24, 1998, the disclosure of which is incorporated herein by reference in its entirety, in its entirety, in Officer 28 and - glass preform 23, the mold includes the lower mold core 25' to heat the glass pre-operation 23 to soften, press the upper mold core 24, the nuclear k-glass lens under pressure and high temperature action, pre-oval molding method The point is that since the glass preform 23-I is a spherical or biconvex cake-like structure, the difference between the upper and lower deformations of the glass lion body 23 is large, and the lower right cost and the processing effect are low. This will cause the energy wave ^ need to get up and down _ the difference is larger == Bu == = ::= is the better way, knowing that heating is for this, it is necessary to provide a position of the mold, so that the mold can be controlled and prepared ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Surface can control the temperature of the mold The present invention provides a heating device for a mold making apparatus, which comprises an upper mold and a lower mold, which is moved along the axial direction thereof. The 敎 body' and the upper and lower dies can be mirrored separately, and the 发出 source emits a 埶 ':, 、, 、, and includes a plurality of heat sources and a plurality of concave faces... the heat s is reflected by the concave mirror and can be wound around the axis , rotate to control the heating point to control the temperature distribution of the mold. , " concave mirror can be carried out two: lifting: the direction of the surface mold rotation, so that the heating point is located in the upper mold, so as to the upper mold, thereby heating the lower mold to increase the temperature of the lower mold. The heating point is located in the lower shovel technology, the concave mirror of the glass-making damage heating device of the invention can be planted with one shaft residual rotation, so the heating shaft can be selected according to the shape of the lens, so that the upper and lower sides can be obtained. Temperature distribution, [Embodiment] From your glass lens. • Glass f f, oracle face. Recording includes a mold 1, the upper mold =: two =;; including - ground. TM 2 is generally a spherical braided structure, pure; 'set == 2, the glass preform:! . Dan X knife..., clothing set 3 sets outside the cookware 1 for heating the mold upper mold 10 includes an upper support 1〇〇 and an upper mold or integrally formed. The upper support and the upper mold core H1 are finely connected to have a larger overall diameter than the cylinder, and the upper bracket is provided with a sectional-first curved ship, and the bottom surface of the upper support 100 of the complementary one is corresponding. . The Mmo is movable up and down with respect to the lower mold 11 in a shape corresponding to the preset molded glass lens. - The vertical position moves along the direction of the machine, that is, the surface straight # is larger than the lower mold core m support no. Set a complex - product 11 〇 -, the edge of the bottom of the lower support 110 corresponds. The mold n can move in the direction of its residual direction between the shape and the position of the preset molded glass lens and the #2 position, that is, the J274741 can move up and down with respect to the upper mold 10.
