Mould opener and mould opening method thereof

Abstract

The invention relates to the technical field of lens manufacturing equipment, in particular to a mould opener and a mould opening method. The mould opener comprises a mainboard, wherein a mould opening mechanism is arranged on the mainboard; the mould opening mechanism comprises a mould fixing seat; a tool rest assembly is arranged above the mould fixing seat; the tool rest assembly is connected with an eccentric wheel through a bearing; the eccentric wheel is driven by a handle to rotate on the mainboard; the tool rest assembly comprises a flat tool bit; the blade of the tool bit faces toward the mould fixing seat below; and the length direction of the blade is consistent with the mould opening direction of a mould on the mould fixing seat. According to the mould opening method, the mould opener is adopted to carry out a mould opening process. By adopting the technical scheme and the mould opening process, the mould opening is time-saving and labor-saving, and the remarkable advantages of being high in mould opening efficiency and low in lens breakage ratio are achieved.

Description

technical field [0001] The invention relates to the technical field of lens manufacturing equipment, in particular to a mold opener and a mold opening method. Background technique [0002] Resin lens is an optical lens made of resin. Because of its significant advantages such as light weight, strong impact resistance, and good light transmission, it is widely manufactured and used. At present, the molds for making resin lenses usually use two molds (one A mold and one B mold) to manufacture resin lenses by casting. After the resin lens is cured, a mold opening process is required. The traditional technique is to squeeze the lens with a plastic mold core to deform the lens and cause the mold to separate from the lens. If the pressure of the forced extrusion of the mold opening lens is slightly too large, a black shadow will appear when the lens is dyed, resulting in unqualified dyeing and scrapping. It is difficult for the mold opening operator to grasp the strength, and ...

AI Technical Summary

Problems solved by technology

If the pressure on the mold opening lens is slightly too high, a black shadow will appear when the lens is dyed, resulting in unqualified dyeing and scrapping

Mold opening operators are not easy to grasp the strength, it is difficult to manage by hand feeling

In addition, the plastic mold core is easy to wear and needs to be continuously improved, resulting in high cost of use

[0003] In addition, when opening the mold, the current mold opening machine usually adopts flat opening, and the operator needs to look down at the mold opening position. If the mold opening position is slightly worse, the mold or lens will be scrapped
