The contact lens is molded by pouring a transparent contact lens manufacturing resin into the mold base, and then applying heat and pressure to sandwich the contact lens mold. When the contact lens molding is completed, the contact lens mold may be separated from the mold base, and the finished contact lens product attached to the bottom of the contact lens mold may be collected.

1 is a perspective view illustrating a coupling state of a contact lens mold and a mold base. In the related art, when the contact lens mold 10 is separated from the mold base 12, an operator manually pulls out the contact lens mold 10 and separates the contact lens mold 10.

In this case, if the worker cannot adjust the force well, the contact lens is damaged and a lot of defective products are generated. In addition, the contact lens mold and the mold base are in a state of considerable heat and pressure, so it is not easy to apply a suitable force to separate them. In addition, because of the manual work progress was slow and the productivity was low.

According to a preferred embodiment of the present invention, the press cylinder is operated by a scaffold formed on the outside of the body, the guide cylinder is operated by a lever formed on the upper plate of the body.

According to a preferred embodiment of the present invention, the press cylinder and the guide cylinder are formed to operate by hydraulic pressure.

According to a preferred embodiment of the present invention, a protective cover is installed outside the guide cylinder to prevent damage to the guide cylinder.

According to a preferred embodiment of the present invention, the pipes are coupled to the top of the pipes so that the pipes move simultaneously with the operation of the press cylinder.

According to a preferred embodiment of the present invention, a lower box is provided at the lower part of the body to accommodate the mold base separated from the contact lens mold by the pressure of the pipe.

Hereinafter, the contact lens mold separating apparatus of the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view illustrating a contact lens mold detachment apparatus according to an exemplary embodiment of the present invention. According to FIG. 2, the contact lens mold separator of the present invention includes a body 110 formed by connecting the frame 114 to a lower portion of the upper plate 112, a press cylinder 120 formed on the body upper plate 112, and the A guide cylinder 130 formed on the side of the body frame 114, a plurality of grooves 137 to be engaged with the step formed on the contact lens mold 10, one side is fixed to the frame 114 and the other The side of the contact lens mold 10 by applying a pressure to the mold base 12 by the operation of the press cylinder 120 and the pair of mold guides 136 formed to be movable by the guide cylinder 130. It includes a plurality of pipes (128) for separating the.

The press cylinder 120 and the guide cylinder 130 are preferably operated hydraulically to apply a constant force and pressure, the press cylinder 120 is operated by the foot plate 122 formed on the outside of the body, the guide cylinder ( 130 is operated by the lever 132 formed on the upper plate of the body. The scaffold 122 and the lever 132 are the press cylinder 120 and the guide cylinder 130 to operate the press cylinder 120 and the guide cylinder 130 by operating the scaffold 122 and the lever 132. And a hydraulic hose 124 are connected. In addition, a protective cover 134 is additionally installed outside the guide cylinder to prevent damage to the guide cylinder 130.

And the fixture 138 is provided in order to fix the mold guide 136 firmly. The groove 137 provided in the mold guide 136 is formed to engage the stepped portion formed on the contact lens mold 10 so that the position of the contact lens mold 10 when the contact lens mold and the mold base are separated. It keeps constant. Therefore, the groove 137 may be formed to surround the step of the contact lens mold 10 by about 1/2.

3 to 5 are plan views illustrating a bonding process of a contact lens mold and a mold guide according to an exemplary embodiment of the present invention.

Initially, the operator installs the stepped portion formed in the upper portion of the contact lens mold 10 and the groove 137a provided in the mold guide 136a fixed to the body frame 114. At this time, the contact lens mold 10 is arranged in two rows, one of which is installed to be engaged with the mold guide 136a.

Then, when the guide cylinder 130 is operated by operating the lever 132, the mold guide 136b connected to the guide cylinder 130 moves to engage the mold guide 136a fixed to the body frame 114. The stepped portion formed in the contact lens mold 10 in a row and the groove 137b of the mold guide 136b are engaged.

As a result, the position of the contact lens mold 10 is fixed by the mold guides 136a and 136b, and the mold base 12 is also fixed together with the contact lens mold 10.

Although not shown, a separate on / off device for operating the guide cylinder 130 may be used instead of the lever 132.

6 and 7 are side views illustrating a bonding process of a contact lens mold and a mold guide according to an exemplary embodiment of the present invention.

One side of the contact lens mold 10 arranged in two rows is installed to engage with the groove 137a formed in the mold guide 136a fixed to the body frame 114.

Then, the guide cylinder 130 is operated to move the mold guide 136b to engage with the row of the unfixed side of the contact lens mold 10 so as to completely fix the position of the contact lens mold 10.

In order to prevent damage to the guide cylinder 130, a protective cover 134 is installed outside the guide cylinder 130.

8 is a side view illustrating a state in which a contact lens mold is separated from a mold base according to an exemplary embodiment of the present invention. According to FIG. 8, after the groove 137 formed in the mold guides 136a and 136b is engaged with the stepped upper portion of the contact lens mold 10, the position of the contact lens mold 10 is fixed, and then the press cylinder 120 is opened. By operation, the contact lens mold 10 and the mold base 12 are separated.

The press cylinder 120 operates by manipulating the footrest 122 formed outside the body. A plurality of pipes 128 are formed below the press cylinder 120. When the press cylinder 120 is operated, the pipes 128 are lowered to apply pressure to the mold base 12 to separate from the contact lens mold 10. Let's do it.

In this case, the contact lens mold 10 maintains a constant position even when separated from the mold base 12 because the contact lens mold 10 is engaged with the mold guide 136. When the contact lens mold 10 and the mold base 12 are separated, the manufactured contact lens remains coupled to the bottom of the contact lens mold 10, so that the operation is completed when the contact lenses are collected.

Under the body 110, a storage box 116 may be installed to collect the separated mold base 12.

Although not shown, a separate on / off device for operating the press cylinder 120 may be used instead of the scaffold 122.

9 and 10 are front views showing the operation of the press cylinder according to an embodiment of the present invention.

According to FIG. 9, a plurality of pipes 128 are installed to pressurize the mold base 12 from the contact lens mold 10 in accordance with the operation of the press cylinder 120. The upper portion of the pipe 128 is coupled to the connecting plate 126 to operate at the same pressure at the same time.

According to FIG. 10, when the press cylinder 120 operates, the connecting plate 126 is lowered by the pressure, and the pipes 128 coupled to the lower portion of the connecting plate 126 apply pressure to the mold base 12. It is separated from the contact lens mold 10.

In the contact lens mold separator of the present invention, the press cylinder 120 and the guide cylinder 130 are operated hydraulically, so that the device can be operated while maintaining a constant force and pressure to reduce the product defect rate.

In addition, since the progression by hand can be completed in a short time, there is an effect of improving product productivity.
