Field of the Invention The present invention relates to a glass mold-forming device, and more particularly to a multi-cavity batch type glass mold-forming device suitable for the manufacture of precision aspheric optical lenses. [Prior Art] According to the conventional method of molding an aspherical optical glass lens, a pair of upper and lower mold cores are formed by a template or a sleeve to form a cavity, and the high temperature softening property of the glass material is utilized. In the hole, the glass material is pressed into a shape by the pressing process of the upper mold core and the lower mold core, deforming and approaching the surface shape and thickness of the desired mold, and then the glass material is cooled and contracted and the viscosity is increased. During the process, the molded lens is appropriately subjected to secondary press molding, and the surface profile of the upper and lower mold cores is thus transferred to the glass material, and finally the optical glass lens of the desired surface shape is obtained. In order to improve the production efficiency and productivity of the glass molding process, a multi-cavity molding device is often used in the production of the industry, as shown in the figure--the basic structure of a conventional multi-cavity glass mold-forming device. The upper template 101 and the lower template are respectively disposed, and a plurality of upper molds 101 are respectively disposed in the upper template 107, and correspondingly, a corresponding number of lower mold cores 104 are disposed on the lower template. The upper mold core (9), the lower mold core 104 and the upper template 107 and the lower template 108 are arranged with a cymbal piece (10), thereby adjusting the upper mold core and the lower mold core U) 4 in the upper template 107 and the lower template. The depth of placement in 1〇8 is such that the thickness of the lens produced by each cavity tends to be H-corrected by the transmission system to drive the upper template or the lower template to move in the vertical direction, and is mounted on the upper template and the lower template. The mold core and the lower mold core are subjected to the action of clamping, opening, and the like, and the aspherical surface lens is molded. 1290540 The glass molding apparatus described above is provided with a plurality of mold cores on a set of templates to form a plurality of mold cavities, thereby greatly improving production efficiency and expanding productivity. However, the upper and lower mold cores of the existing molding device are respectively fixedly installed in the upper and lower templates, and the movement of the upper and lower templates is driven by the transmission system to generate a mold clamping, mold opening, etc., if one of the mold cores is defective. , the entire template must be dismantled to replace the components, bribes delay production, or bribes to deal with 'but if the number of plugs increased, the production capacity must be reduced accordingly. In addition, since each pair of mold cores adjusts their relative height by the wire, the thickness of the aspherical glass lens which is pressed by each cavity is uniform, and it is necessary to accurately calculate and control the size of the gasket and perform high-precision installation. And debugging so that the height m of each mold core will cause _, the mold repair process is cumbersome and lengthy 'requires skilled craftsmen to spend a lot of time and effort. Therefore, it is extremely necessary to improve the production efficiency and productivity by improving the conventional mold making (4), reducing the _, and reducing the complexity of the work. SUMMARY OF THE INVENTION The object of the present invention is to provide a problem that the product thickness is uneven due to the difficulty in adjusting the gasket, and simplifying the mold assembly, debugging and repairing of the molding device. The _ type, to avoid delays in the process due to plugging or disassembly, thereby improving production efficiency and productivity. The glass mold-forming device that is not supplied by the moon includes the upper template, which has a plurality of holes. Each of the holes is provided with an upper die; a lower die, the lower die is provided with a plurality of holes corresponding to the positions of the holes of the upper die plate; and a lower portion corresponding to the position of each of the holes below the lower die plate , shot, each - the movable shaft end material 1290540 has a mold core, the lower mold core can move with the movable axis in the corresponding hole of the lower template, and cooperate with the upper mold core in the hole of the upper template to form a glass mold. In the glass mold-making device provided by the present invention, the movable shaft can adopt a hydraulic shaft or other hydraulic shaft and a pneumatic shaft. When used, the upper template of the glass mold-forming device is lowered, and the positioning pin and the lower template are borrowed. The upper hole is matched with the holes of the upper and lower template one by one, and then the movable shaft is raised to make the lower mold core close to the mold, and the correct distance is used to correct the height of each lower mold. Thus, a molded glass lens having a uniform thickness can be obtained. Compared with the prior art, the present invention precisely controls the pressing position of the cavity by controlling the height of the lower mold core by the movable shaft, thereby obtaining a finished product having a uniform thickness, and eliminating the conventional device. The complicated and complicated process of adjusting the gasket in the mold and the debugging, and adopting the movable shaft to control the opening and clamping of the mold core, it is convenient to dismantle the mold cavity without affecting the normal use of other mold holes, thereby avoiding Due to the serious stagnation of the production process, the work efficiency and the production efficiency of the machine device are improved.
