Contact lens processing mold

Abstract

The present invention provides a contact lens processing mold, which comprises: a body provided with a first surface and a second surface, wherein the first surface and the second surface are opposite, and one end of the body is provided with a force applying part; a concave cup formed on the first surface of the body and projecting toward the second surface; and a plurality of fixed holes arranged on the body. According to the present invention, the unnecessary procedure manufacturing investment and waste can be saved, the injection mold use amount can be reduced, and the hydration demolding program is not used so as to complete the contact lens production; and with the contact lens processing mold, the effect that the procedure manufacturing complexity is reduced to reduce the production cost so as to improve the productivity and the qualification rate can be achieved.

Description

technical field [0001] The invention relates to a contact lens processing mold, in particular to a contact lens processing mold which can reduce the complexity of the manufacturing process, thereby reducing the production cost and improving the production capacity and qualification rate. Background technique [0002] The manufacturing and production of contact lenses are common methods of mold casting and rotary molding. The production efficiency of mold casting is currently recognized as the most efficient way, but the investment required and the complexity of technology and equipment are also very huge. Challenges, and the spin-molding method is critical that it cannot produce contact lenses in large quantities, but the required investment is more advantageous than the mold-casting method. However, the plastic injection mold required in the production process must be discarded after use, and It cannot be reused. Because contact lenses are medical products, the molds in the...

Problems solved by technology

[0004] The aforementioned "packaging method for disposable contact lenses" and "container for contact lenses", both technical solutions use the master model in production as the packaging style. Although some manufacturers try to save the packaging method of contact lens injection blisters, they still When the master model is used to replace the PP cup that needs additional injection when the production is completed, the design is mainly based on the convenience of production considerations, and the user has no support point and force when tearing the aluminum foil when picking up the contact lens. The arm is easy to cause inconvenience to the user, so the plastic bulb with the support point and the force arm will still be injected again for the convenience of the user, so the plastic bulb with the support point and the force arm will be newly injected or Auxiliary parts will incur considerable costs
