Description
Technical Field
[0001] The utility model relates to the technical field of contact lens production, in particular to a plastic mould shelling machine. Background Art
[0002] Contact lenses, also called contact lenses or contact glasses, are lenses that are worn on the cornea of the eye to correct vision or protect the eyes. Cosmetic contact lenses are contact lenses.
[0003] Contact lenses are made by pouring liquid hydrogel into a hemispherical die, which is then pressed together with a hemispherical punch. The contact lenses are formed after the liquid hydrogel solidifies. When the contact lenses need to be taken out of the two hemispherical molds, the punch needs to be squeezed out with the help of a punch. At this time, the contact lenses will be attached to the punch, but the extrusion of the punch will cause the die, punch, and contact lenses to be scattered together. Workers are also required to manually take the contact lenses and sort the die and punch, which seriously affects production efficiency. Utility Model Content

[0024] The demoulding mechanism 9 includes a piston 91, a push rod 92, an air pipe 93, and a hose 94; the piston 91 is slidably connected to the inner wall of the slider 83, and the push rod 92 is fixedly installed on the side wall of the piston 91. The end of the push rod 92 away from the piston 91 passes through the slider 83, and the push rod 92 is slidably connected to the penetration of the slider 83. The piston 91 is pushed by the push rod 92, so that the piston 91 squeezes the air inside the slider 83 into the inside of the air pipe 93. The air pipe 93 is fixedly installed on the inner wall of the slider 83, and the hose 94 is fixedly installed on the outer wall of the air pipe 93.
