Description

Technical Field

[0001] The present invention belongs to the technical field of contact lens mold material distribution, and specifically relates to a single-row material distribution device for contact lens molds. Background Art

[0002] When contact lenses are produced, resin molds are needed to shape the contact lenses, so that the silicone hydrogel can be injected into the resin mold for curing and molding. When the resin molds of contact lenses are produced, injection molding machines are needed for batch processing. When the resin molds of contact lenses are molded, the molds are also needed to cure the resin, so that the resin molds can mold the contact lens raw materials.

[0003] In order to maximize the material output during a single mold injection while also achieving high quality and minimal waste, molds are usually molded in a petal-shaped format, meaning the molds are equidistantly distributed in a ring shape, and the molds are connected in the middle by runners.

[0004] In order to facilitate subsequent work such as die pressing, pattern pad printing and demoulding in subsequent production, it is necessary to cut off the flow channel in the middle of the petal-shaped mold, and at the same time, molds of different types can be sorted and processed regularly. After the molds of the same type are placed on the same rack, the molds on the rack are transported to subsequent steps such as steaming and hydration, die pressing, pad printing and batch demoulding.

[0005] However, most of the existing methods of splitting runners use a shear seat to cut the mold and runner, and then collect the materials by automatically falling down during the cutting process. Subsequently, a vibrator or manual arrangement and loading process is used. Therefore, it is necessary to have a set of automatic cutting and loading devices that can also automatically load and load materials to improve production efficiency. Utility Model Content
