Description

Technical Field

[0001] The utility model relates to the field of automatic processing equipment for non-spherical glass, in particular to an automatic upper mold core mechanism for non-spherical glass. Background Art

[0002] Optical lenses are usually made by die casting (i.e., molding) in order to improve the production efficiency of optical lenses. However, for aspherical glass, the processing requirements are higher. The processing mold can refer to Chinese patent CN202223211852.4, which includes a sleeve, an upper mold core and a lower mold core. During the processing, the upper mold core and the lower mold core are extruded to realize the extrusion molding of the glass ball.

[0003] However, the upper mold core of the existing aspherical glass is generally processed in two steps, that is, the upper mold core is first die-cast, then the upper mold core is taken out by a second mechanism, and finally the upper mold core is taken out again. The processing steps are relatively large, so the production line is relatively long. Utility Model Content

[0004] The main purpose of the utility model is to provide an automatic upper mold core mechanism for non-spherical glass, aiming to improve the existing upper mold core structure and realize the pressing and forming and synchronous removal of the upper mold core.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes an automatic upper mold core mechanism for non-spherical glass, comprising:

[0006] A vertical moving device, wherein the vertical moving device is installed on the frame;

[0007] A positioning seat, wherein the positioning seat is arranged on a vertical moving device, and the vertical moving device can drive the positioning seat to move vertically;

[0008] A driving seat, which is arranged at the lower wall of the positioning column, a slidably arranged pressure column is arranged in the middle of the driving seat, and a first driving device for driving the pressure column to move vertically is arranged on the driving seat, and the bottom end of the pressure column can be against the top wall of the upper mold core;

[0009] A clamping arm, wherein the clamping arm is provided in plurality and is slidably mounted on the lower wall of the driving seat, wherein the driving seat is provided with a second driving device for driving the clamping arm to slide, and wherein the second driving device drives the end of the clamping arm to move between a position moving toward the axis or a position away from the axis;

[0010] The end of the clamping arm can be used to clamp the upper wall of the upper mold core.

[0011] In actual operation, when the upper die core needs to be clamped, the multi-axis moving frame drives the upper die core to move vertically to the position of the upper die core, and clamps it through the clamping arm, and then moves to the position of the sleeve and drives the upper die core to move downward into the sleeve through the vertical moving device;

[0012] Then the clamping arm moves to a position away from the axis, at which time the upper mold core contacts the glass ball. At the same time, the first driving device drives the pressing column downward until the non-spherical glass ball is formed, and then the pressing column moves upward, and finally the clamping arm clamps the upper mold core and moves upward;

[0013] The dual-stage travel mode of the vertical moving device and the first driving device can effectively reduce the height of the processing mechanism. The structure of the clamping arm and the pressure column as one can effectively simplify the loading and clamping steps of the upper die core, and also facilitate the replacement of the upper die core (that is, after a period of processing, the upper die core will have residues due to the influence of materials and temperature.
