[0002] Optical glass is a special glass material mainly used in the optical field, which can change the propagation direction of light and change the relative spectral distribution of ultraviolet, visible or infrared light, including various types such as colorless optical glass, colored optical glass, laser glass, quartz optical glass, radiation-resistant glass, ultraviolet and infrared optical glass, fiber optical glass, acousto-optic glass, magneto-optic glass and photochromic glass.

[0003] The operation process of optical glass molding is loading - molding - cooling - unloading. The traditional optical glass molding device does not have a good unloading function for the optical glass after molding, and the traditional optical glass molding device has only one molding cylinder. After the molding is completed, during the waiting process for the glass to cool, the operation of the entire device is greatly delayed. How to reasonably allocate the time of each process is the problem to be solved this time. Summary of the Utility Model

[0004] To solve the above problems, the utility model discloses a high-precision molding device for optical glass production, and the utility model is realized through the following technical solutions.

[0005] A high-precision molding device for optical glass production includes a base, a hydraulic cylinder, a mounting cylinder and a molding cylinder. Support legs are fixedly connected to the four corners of the lower surface of the base. Four limiting rods are fixedly connected to the upper surface of the base in a circumferential and uniform manner. A top plate is fixedly connected to the top of the limiting rods. The hydraulic cylinder is fixedly connected to the top plate. The output shaft of the hydraulic cylinder is fixedly connected to a molding plate. The molding plate is slidably connected to the limiting rods. A molding head is fixedly connected to the center of the lower surface of the molding plate. A turntable is rotatably connected to the base. Three mounting cylinders are fixedly connected to the turntable in a circumferential and uniform manner. The molding cylinder is slidably connected in the mounting cylinder. Positioning screws are symmetrically engaged with the front and rear of the upper part of the mounting cylinder. Fixing holes corresponding to the positioning screws are formed on the outer wall of the molding cylinder.

[0006] Further, the molding cylinder is composed of two left and right semi-cylinders.

[0007] Further, a limiting groove is formed on the base. A limiting block corresponding to the limiting groove is fixedly connected to the bottom of the turntable.

[0008] Further, a fixed cylinder is fixedly connected to the base. A telescopic rod is slidably connected in the fixed cylinder. A clamping block is fixedly connected to the end of the telescopic rod. A spring is fixedly connected between the fixed cylinder and the clamping block. Three card slots corresponding to the clamping block are formed on the turntable in a circumferential and uniform manner.

[0009] Furthermore, a support column is rotatably connected to the bottom of the turntable, and the support column is fixedly connected to the base through a connecting rod.

[0010] The technical solution provided by the present utility model has the following beneficial effects compared with the known public technology: by setting the molding cylinder as two semi-cylinders, it is possible to more easily take out the optically molded glass in the molding cylinder after molding. By setting three mounting cylinders and molding cylinders on the turntable, it is possible to produce optical glass more efficiently. After the optical glass is molded, the turntable can be rotated to turn away the molding cylinder and placed aside for cooling, and the adjacent molding cylinder filled with materials can be rotated under the molding head to continue molding, greatly improving the production efficiency.

[0020] Preferably, a limiting groove 191 is provided on the base 1, and a limiting block 192 corresponding to the limiting groove 191 is fixedly connected to the bottom of the turntable 14.

[0027] In the optical glass molding activity, the optical glass material to be molded is placed into the molding cylinder 4. The turntable 14 is rotated until the card slot 19 in front of the molding cylinder 4 containing the optical glass material to be molded is engaged with the block 17 on the base 1. Then, the hydraulic cylinder 2 is opened, and the push rod of the hydraulic cylinder 2 will drive the molding plate 21 to move up and down. The molding head 22 at the bottom of the molding plate 21 will mold the optical glass in the molding cylinder 4. During the optical glass molding process, the adjacent molding cylinder 4 is loaded with materials. After the molding is completed, the turntable 14 is rotated to turn the molding cylinder 4 containing the molded optical glass to one side for cooling, and the adjacent molding cylinder 4 filled with the optical glass material is rotated under the molding plate 21 for molding.
