Description
[technical field]
The present invention relates to a kind of glass mold forming apparatus, refer to a kind of multi-point mould type glass mold forming apparatus that is applicable to that accurate aspherics eyeglass is made especially.
[background technology]
The model method of existing aspherics glass mirror, be with a template or sleeve cooperate paired on, following die is to form die cavity, and utilize the hot mastication characteristic of glass material, in die cavity, reach the pressure process of die down by upper cores, glass material is pressed the type that causes, make its distortion and approaching pre-interim surface shape and the thickness that is molded as product, in the process that the glass material cooling is shunk and viscosity raises, give the model eyeglass suitable secondary extrusion forming more subsequently, on, the surface shape of following die is incited somebody to action therefore transcription on glass material, and finally obtains the optical glass lens of required surperficial face shape degree.
For improving the production efficiency and the production capacity of glass moulding processing procedure, industrial community often adopts multi-point mould pattern manufacturing apparatus on producing at present, be a kind of essential structure of existing multi-point mould type glass mold forming apparatus as shown in Figure 1, it comprises top plate 107 and lower bolster 108, several upper cores 101 are placed in respectively in this top plate 107, and correspondingly settle some dies 104 down of corresponding number on lower bolster 108.Dispose pad 109 between these upper cores 101, following die 104 and top plate 107, the lower bolster 108, to adjust upper cores 101, the following placement degree of depth of die 104 in top plate 107, lower bolster 108, make each die cavity press the lens thickness of producing to reach unanimity.Drive top plate or vertically activity of lower bolster by transmission system during production, make the upper cores, the actions such as die generation matched moulds, die sinking down that are fixedly mounted on top plate and lower bolster, thereby finish the model of aspheric surface glass mirror.
Aforementioned glass moulding device is provided with a plurality of dies on the template and forms a plurality of die cavitys at a cover, thereby can increase substantially production efficiency and enhance production capacities.Yet the upper and lower die in this existing moulding device is to be fixedly mounted on respectively in the upper and lower template, drive upper and lower template motion by transmission system and produce actions such as matched moulds, die sinking, if certain die defectiveness wherein, then whole template dismounting just can must be carried out spare part changes, so that incur loss through delay and produce, perhaps handle, but if plug cave quantity increases, then production capacity must correspondingly reduce in plug cave mode.In addition, because each all is to adjust its relative height by pad to die, be the aspheric surface glass mirror gauge unanimity of guaranteeing to extrude by each die cavity, need accurate calculation and control shim size, and carry out high-precision installation and debugging so that the height unanimity of each die, therefore can make gang mould, the process that repairs a die is loaded down with trivial details and tediously long, needs the skilled manpower to spend a large amount of time and efforts.Therefore, the utmost point is necessary to improve the defective of existing moulding device, with reduction group mould, the man-hour and reduce its fussy degree of repairing a die, thereby enhances productivity and production capacity.
[summary of the invention]
The object of the present invention is to provide a kind of glass mold forming apparatus, to solve existing moulding device is difficult for adjusting the product thickness inequality that causes because of pad problem, and the complicated procedures of simplifying moulding device group mould, debugging and repair a die, avoid incuring loss through delay processing procedure, thereby enhance productivity and production capacity owing to plug cave or dismounting repair a die.
The objective of the invention is to be achieved through the following technical solutions: glass mold forming apparatus comprises top plate, lower bolster and movable axis, and wherein top plate is provided with some holes, respectively is equiped with a upper cores in each hole; Lower bolster is provided with and some one to one holes, the position, hole of top plate, movable axis is located at below the lower bolster and corresponding to each hole, wherein, each movable axis end is provided with die, this time die can be movable in the hole of lower bolster correspondence with movable axis, and cooperate the die cavity that is formed for glass moulding with upper cores in the hole of top plate.
In the glass mold forming apparatus provided by the present invention, movable axis can adopt oil pressure axle or other hydraulic axis, airpressure axle.
During use, the top plate of glass mold forming apparatus descends, aim at accurate combination one by one by the fastening screw hole that makes upper and lower template of matching with pilot hole on the lower bolster, movable axis rises then, to descend the die die that makes progress to draw close matched moulds, utilize input to make each time die height unanimity apart from compensating value accurately, thereby can obtain the modeling glass lens of consistency of thickness.
Compared with prior art, the present invention accurately controls the pressing position of die cavity by the height of die under the movable axis control, thereby obtain the uniform finished product of thickness, the very complicated process of having avoided existing apparatus group mould, debugging Intermediate gasket to adjust, and adopt movable axis the control die sinking and the matched moulds of die down, be convenient to flaw die cavity wherein dismantled and repair a die and do not influence the normal use of other die cavity, block up thereby avoid procedure for producing being caused seriously, improved the productive efficiency of operating efficiency and installations because of repairing a die.
