Description

Contact lens overturning and suction mold head

The technical field is as follows:

the utility model relates to a contact lens processing equipment, concretely relates to contact lens upset suction mould head.

Background art:

the color contact lenses are also called as beauty pupils, not only can correct the vision of a wearer, but also can change the color of the pupils to achieve the effect of beautifying the eyes, and the color contact lenses are increasingly popular among young people as popular beauty products in recent years. The process of making a colored contact lens generally comprises the steps of printing a designed pattern on a mold, injecting a liquid material for forming the contact lens into a cavity formed between a male mold and a female mold, pressing the male mold and the female mold together, and finally curing the liquid material to obtain the formed contact lens.

In the production process of the contact lenses, plastic molds such as male molds, female molds and the like suitable for the process flow are generally produced by an injection molding machine, and then the production is completed by relying on the molds in each production procedure. The circulation of the dies among various production processes or in a single process needs to use various circulation tools, and how to accurately convey each die from a previous station to a next station directly determines the production fluency and production efficiency. In this situation, there is a need for a mechanism that has a low failure rate and can effectively transport the mold, thereby effectively ensuring the smoothness of the contact lens production and further ensuring the production efficiency.

The invention content is as follows:

an object of the utility model is to provide a upset suction die head aims at improving production efficiency. The specific technical scheme is as follows:

a contact lens inverting suction die head, comprising: a rotating mechanism and a telescoping mechanism on the rotating mechanism;

the telescopic mechanism comprises a pair of convex suction die heads which are symmetrically distributed and move oppositely, a pair of slide blocks which are fixedly connected with the convex suction die heads respectively, and a chute positioned on the rotating mechanism; the raised suction die head is connected with the sliding block through a bolt.

Preferably, the raised suction die head comprises two parts: the upper vertical protrusion and the lower telescopic member are connected with the sliding block through bolts.

The utility model has the advantages that: the utility model discloses in upset suction die head do not adopt compressed gas to absorb the mould, but adopt the pressure between device and the mould to fix the mould, can prevent effectively that the mould from dropping to guarantee the smoothness nature of production, and then guarantee production efficiency.

Description of the drawings:

FIG. 1 is a schematic view of an embodiment of a contact lens inverting suction die structure; in the figure, 1 represents a rotating mechanism, 2 represents an upper vertical projection, 3 represents a lower telescopic member, 4 represents a slider, and 5 represents a chute.

FIG. 2 is a schematic right side view directional structure of FIG. 1; in the figure, 1 represents a rotating mechanism, 2 represents an upper vertical projection, 3 represents a lower telescopic member, 4 represents a slider, 5 represents a chute, and 6 represents a bolt.

The specific implementation mode is as follows:

example (b):

a contact lens inverting suction die head, comprising: a rotating mechanism 1 and a telescopic mechanism positioned on the rotating mechanism;

the telescopic mechanism comprises a pair of convex suction die heads which are symmetrically distributed and move oppositely, a pair of sliding blocks 4 which are respectively fixedly connected with the convex suction die heads, and a sliding chute 5 which is positioned on the rotating mechanism; the convex suction die head is connected with the sliding block through a bolt 6; the raised suction die head comprises two parts: the upper vertical protrusion 2 and the lower telescopic member 3 are connected with the sliding block through bolts.

The working process of the contact lens overturning suction die head is as follows: the mechanical arm controls the device to come to the position of a mold, at the moment, a pair of upper vertical protrusions of the mold suction head are in a closed state, the vertical protrusions of the mold suction head are inserted into an inner cavity of the mold, then the telescopic mechanism stretches out, the vertical protrusions support the inner cavity of the mold, and then the rotating mechanism turns over for 180 degrees clockwise; then the mechanical arm controls the die sucking head to go to the next station, the die is placed on the next station, and then the telescopic mechanism retracts, so that the die is released, and the die transfer is completed.
