Embodiment 1

[0028] A device for measuring the opening force of an optical lens mold, comprising a mold tray 1, a base 2, a vertical plate 3, a pressure head rod 4, a connecting block 5, a hand pressure rod 6, a connecting rod 7, a sensor 8, a guide ring 9, and a pressure head 10. Lens mold 11, the vertical plate 3 is fixed on the base 2, the vertical plate extension 31 is arranged above the vertical plate 3, one end of the hand pressure rod 6 is rotationally connected with the vertical plate extension 31, and the other end is connected with the connecting block One end of 5 is movably connected, and the other end of described connecting block 5 is movably connected with an end of connecting rod 7, and the other end of described connecting rod 7 is connected with one end surface of sensor 8, and described guide ring 9 is a middle pass cylindrical shape with two All are fixed on the extension end 31 of the vertical plate, and one end of the pressure head rod 4 passes through the guide ring 9...

Embodiment 2

[0033] The rest of the structural features of Embodiment 1 remain unchanged, only the shape and connection mode of the connecting block 5 are changed. In addition to being movably connected with the connecting rod 7, the connecting block 5 can also be pressed with the connecting rod 7 through surface contact. The connection in this embodiment The shape of block 5 is cam shape, and one side of cam contacts with connecting rod 7 faces, when working, the power of hand pressing lever 6 can be transmitted to connecting rod 7 by cam-shaped connecting block 5, and press down.

Embodiment 3

[0035] The rest of the structural features of Embodiment 1 remain unchanged, and the sensor 8 can be arranged between the indenter 10 and the indenter rod 4 in addition to being connected to the indenter rod 4 and the connecting rod 7 . When the sensor 8 is arranged between the indenter 10 and the indenter rod 4, one end surface of the sensor 8 is connected to the indenter 10, the other end is connected to one end of the indenter rod 4, and the other end of the indenter rod 4 is connected to the connecting rod 7 is directly connected, and the size of the mold opening force can also be detected. At this time, the role of the two guide rings 9 is to allow the connecting rod 7 and the pressure head rod 4 to pass through to limit the direction of the force, and the distance between them is not required.

Abstract

The invention discloses a device for measuring mold opening force of an optical lens mold. The device comprises a mold tray, a base, a vertical plate, a pressure head rod, a connecting block, a hand pressure rod, a connecting rod, a sensor, a guide ring, a pressure head and a lens mold. The sensor is arranged to detect the data of the mold opening force of the mold opening equipment during mold opening in real time, and the mold opening force data detected in real time can be used as an important reference basis for designing the automatic mold opening equipment of the lens mold; the device is not limited to a single lens mold, and can be used for detecting the mold opening force of lens molds with different diameters and thicknesses.

Description

technical field [0001] The invention relates to the technical field of measuring the opening force of an optical lens mold, in particular to a measuring device for the opening force of an optical lens mold. Background technique [0002] For the spectacle lens industry, the mold opening method of the lens mold is as follows: the operator first manually fixes the lens mold, then aligns the mold opening knife with the gap of the lens mold, then hits the mold opening knife with a hammer, and finally separates the lens mold. This method is completely manual, which not only has high labor costs and low work efficiency, but also easily damages the lens when the hammer hits the mold knife, thereby reducing the product quality. In addition, some manufacturers use automatic equipment for mold opening. However, whether it is manual mold opening or automatic mold opening, the problem that the mold opening force is unknown during the mold opening process still cannot be solved, and the m...
