Automatic mold separating device for upper mold and lower mold of contact lens

Abstract

The invention discloses an automatic mold separating device for an upper mold and a lower mold of a contact lens. The automatic mold separating device comprises a mold separating rotary disc, a feeding rotary disc and a discharging rotary disc, wherein the feeding rotary disc and the discharging rotary disc are located on the left side and the right side of the mold separating rotary disc; the mold separating rotary disc, the feeding rotary disc and the discharging rotary disc are arranged on a mold separating rotary disc rotating shaft, a feeding rotary disc rotating shaft and a discharging rotary disc rotating shaft correspondingly and connected with a driving mechanism through a synchronizing mechanism. Station notches are formed in the edges of the mold separating rotary disc, the feeding rotary disc and the discharging rotary disc correspondingly; an upper mold pressing mechanism and a lower mold pressing mechanism are arranged on the upper side and the lower side of the mold separating rotary disc correspondingly; a feeding cutter is arranged on the edge of the feeding rotary disc; an upper mold limiting block, a lower mold limiting block, a main mold separating cutter, an auxiliary mold separating cutter and an upper mold discharging rail are sequentially arranged on the edge of the mold separating rotary disc; and a lower mold limiting block is arranged on the edge of the discharging rotary disc. By means of the automatic mold separating device, continuous and automatic separation of the upper mold and the lower mold of the contact lens is achieved, the risk that products make contact with dust can be reduced, lens damage caused by mold separating can be avoided, the mold separating yield is increased, the mold separating production efficiency can be improved, and the labor cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of automatic production and manufacture of contact lenses, and in particular relates to an automatic mold splitting device for upper and lower molds of contact lenses. Background technique [0002] In the production and manufacturing process of contact lenses, contact lens lenses are made by closing the upper and lower molds. After the contact lens is made, it is first necessary to separate the upper and lower molds, the lens is adhered to the curved surface of the separated lower mold, and then the lens is taken out from the lower mold. At present, most of the upper and lower molds are separated by manual semi-automatic tooling. This method leads to low production efficiency of contact lenses and increased labor costs, which is not suitable for mass production. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides an automatic parting device for the upp...
