Description

Technical Field

[0001] The present invention belongs to the technical field of contact lens six-petal injection molding workstations, and specifically relates to a six-petal male and female mold injection molding disk and discharge dual-discharge combined workstation. 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] Usually, in order to facilitate subsequent work such as die pressing, pattern pad printing and demoulding in subsequent production, and also to maximize the material output during a single mold injection, the mold injection changes the original single-size single injection molding machine's single-mold injection form to a multiple-petal-shaped mold injection form, that is, the mold shape is distributed in an annular shape with equal distances, and the mold is connected in the middle by a runner. The annularly distributed mold can obtain multiple molds of different specifications after one injection molding, thereby greatly increasing production efficiency.

[0004] This petal-shaped mold is usually loaded directly into the material tray after injection molding, which is convenient for transportation to the subsequent runner removal and material separation steps. After the material separation is completed, the mold is directly poured into the vibrating feeder for subsequent resin injection and compression molding.

[0005] However, since there are still a number of old-fashioned discharge production equipment in the existing resin injection compression molding production equipment, although the efficiency is not as high as the new ones, it can ensure long-term normal and stable production. Therefore, if all the old equipment are directly dismantled and replaced, it will cause a huge waste of costs. Therefore, a combined workstation that can not only discharge materials in a petal-type mold but also in the form of discharge is needed. Utility Model Content
