Abstract
The utility model relates to a thickness controlling mechanism for the automatic molding machine of resin eyeglass and includes an upper locking cylinder arranged on an upper locking block; a knockout pin longitudinally passes through the upper locking block in a sliding way. A lower locking cylinder is arranged under a lower locking block; a lower knockout pin longitudinally passes through the lower locking block to form a sliding pair; the lower knockout pin is fixedly connected with a rack; a gear engaged with the rack is fixedly sleeved on the main shaft of a stepping motor; an upper sucking disc which can absorb on the upper molding piece is arranged at the end of an upper absorbing rod linked with an upper locking piece. The utility model adopts computer program controller to control the operation of the air cylinder and the stepping motor, simplifies the manufacturing technology of the mold and improves the production efficiency.
Description
Technical field:
The utility model relates to the eyeglass maker, particularly the thick controlling organization of the sheet of the automatic moulding machine of resin lens.
Background technology:
Making various eyeglasses, such as resin eyeglass.At first will make the base sheet on maker, polishing is trimmed to eyeglass then, eyeglass number of degrees difference, and sheet is thick also different.When producing now bad sheet, a common style number (number of degrees) just needs to make a secondary aluminium-making mould, causes mould various, and operation increases, and production cost rises.
Summary of the invention:
The purpose of this utility model provides a kind of thick controlling organization of sheet that can make the automatic moulding machine of different-thickness resin lens.
The utility model comprises the last locking cylinder that is installed in latch segment, the longitudinally-slidable latch segment that runs through of upper ejector pin, the piston rod of wherein going up locking cylinder can push the brake apparatus of upper ejector pin, it is characterized in that latch segment is equipped with down locking cylinder down, lower push rod vertically runs through latch segment composition sliding pair down, lower push rod is fixedlyed connected with tooth bar, is placed in the stepper motor main shaft admittedly with the tooth bar meshed gears, with the last soup stick bottom of last latch segment interlock the last sucker that can adsorb matrix is housed.Tooth bar, the vertical rod that is with spring and lower push rod is fixedly connected is integral.The upper ejector pin lower end is with spring.
The utility model adopts locking cylinder and the stepper motor by microcomputer program controller control, make that the lower push rod amount of feeding is controlled to be remembered, according to the thick instruction of default sheet, only need an aluminium-making mould just can make the glasses base sheet of all thickness, simplified Mold Making technology, improve production efficiency, reduced production cost.
Description of drawings:
Fig. 1 is the utility model embodiment front view.
Fig. 2 is the left view of the thick controlling organization of Fig. 1 sheet.
Fig. 3 is a base sheet shaping schematic view.
The specific embodiment:
See figures.1.and.2, last locking cylinder 2 levels are installed on latch segment 12, and upper ejector pin 1 vertically runs through latch segment 12, and can slide up and down therein, and the piston rod of cylinder 2 can be pressed and be touched cambered surface fixture block (not drawing among the figure), to realize the locking to upper ejector pin 1.Upper ejector pin 1 lower end is with spring 11, to guarantee the accurate of upper ejector pin amount of movement.Following locking cylinder 3 levels are installed on down latch segment 10, and latch segment 10 also can slide up and down therein under lower push rod 8 vertically ran through, and wherein the piston rod of cylinder 3 can be pressed and be touched cambered surface fixture block (not drawing among the figure), to realize the locking to lower push rod 8.Lower push rod 8 is fixedlyed connected with tooth bar, and gear 13 is formed rack-and-pinion with tooth bar 7, and gear 13 is fixedlyed connected with stepper motor 9 main shafts.There is column 17 on tooth bar 7 sides, and column 17 is fixedlyed connected with tooth bar 7, is with spring 6 on the column.Tooth bar 7, column and lower push rod 8 can be made into one.
With reference to Fig. 3, there are air flue 18 and air flue 25 respectively to communicate in last soup stick 16, the following soup stick 24 respectively with its suction and discharge cylinder, each is equipped with sucker 19,23 up and down respectively the soup stick top, and matrix 20,22 about adsorbable respectively.After the thick position of sheet was determined by last lower push rod, the adhesive tape wind can be the resin-cast die cavity to the side of matrix up and down along twining adhesive tape 21 in it automatically.Above-mentioned each locking cylinder, suction cylinder and stepper motor are controlled by microcomputer program controller.
When starting working, lower push rod 8 is got back to original position, and following locking cylinder 3 acts on down latch segment 10, following latch segment 10 locking lower push rods 8, and last latch segment 12 loosens, and upper ejector pin 1 can be free to slide in last latch segment 12.At this moment, last latch segment moves down, run into upward matrix 20 up to last soup stick 16 bottoms, upper ejector pin 1 pushes up mutually with lower push rod 8, this moment, program controller was remembered this range data, and control is simultaneously gone up locking cylinder 2 and acted on latch segment 12, made latch segment 12 locking upper ejector pins 1, air valve is simultaneously air-breathing by pore 18 and pore 25, and last sucker 19 holds matrix 20 and following matrix 22 simultaneously with following sucker 23.Last retaining mechanism drives to be gone up soup stick 16 and upward moves taking-up aluminum dipping form sheet on the matrix 20.Following latch segment 10 loosens, and by stepper motor 9, control gear 13 turns over certain angle, and then the control distance of moving or moving down on the tooth bar 7, and just the upper ejector pin remembered of program controller moves down distance.After lower push rod 8 moves to the instruction distance, following latch segment 10 lockings.Last retaining mechanism drives to go up soup stick 16 and go up matrix 20 and moves down, and pushes up mutually with lower push rod 8 up to upper ejector pin 1.At this moment, to have reached with aluminium ingot thickness be standard to last soup stick 16.Increase or reduce lens thickness on this basis, i.e. the thickness of die cavity 26, thus reach required lens thickness.Again around matrix up and down around on adhesive tape, to die cavity 26 in, inject resin formation embryo sheet.The top power that spring 6 produces makes the tooth bar 7 and the gap of gear 13 always be positioned at same direction before gear 13 rotations with after the rotation, thereby gash spacing error is dropped to minimum.
