Description

Technical Field

[0001] The utility model relates to the technical field of contact lens production, in particular to an automatic ejecting mold machine for contact lens production. Background Art

[0002] Automatic mold ejection machines for contact lens production play an indispensable role in the contact lens manufacturing process. These highly sophisticated machines utilize advanced automation technology and play a key role in the contact lens molding process. Their operating principle is based on precise mechanical motion and program control. Once the contact lens material is initially formed in the mold, the ejection machine accurately ejects the mold according to pre-set parameters.

[0003] For example, the utility model disclosed in announcement number CN219946991U discloses a contact lens mold, comprising: a first mold, the first mold having a male mold portion, a first clamping portion disposed around the male mold portion; and a second mold, the second mold having a female mold portion, a second clamping portion disposed around the female mold portion. After the first mold and the second mold are assembled, a molding cavity for the contact lens is formed between the male mold portion and the female mold portion, and the first clamping portion and the second clamping portion are engaged to prevent the first mold and the second mold from separating. By disposing the first clamping portion around the male mold portion and the second clamping portion around the female mold portion, the first clamping portion and the second clamping portion are engaged to prevent the first mold and the second mold from separating. Thus, an engagement connection can be performed around the molding cavity, thereby making the engagement connection between the first mold and the second mold more secure and stable, and preventing the first mold and the second mold from bouncing apart due to expansion caused by heating.

[0004] Similar to the above applications, there are still the following shortcomings: the contact lenses after molding are difficult to demold. Utility Model Content

[0005] The utility model discloses an automatic mold ejecting machine for contact lens production, aiming to solve the technical problem that the contact lenses are difficult to demould after being formed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An automatic ejecting mold machine for contact lens production includes a base, the top of the base is fixedly connected to a first fixing frame, the upper surface of the first fixing frame is fixedly connected to a second fixing frame, the end of the second fixing frame is fixedly connected to a mold mechanism, the mold mechanism includes a first fixing plate, the side of the first fixing plate is fixedly connected to a limiting rod, the two ends of the limiting rod are symmetrically rotatably connected to a rotating frame, the end of the rotating frame is fixedly connected to the second fixing plate, and the inner wall of the second fixing plate is fixedly connected to a bottom mold; the end of the first fixing frame is fixedly connected to a demolding mechanism, the demolding mechanism includes a fixing frame, the fixing frame is fixedly connected to the end of the first fixing frame, and the inner wall of the fixing frame is fixedly connected to a motor.

[0008] By setting up a mold mechanism, the contact lens can be shaped, and after the contact lens is shaped, the bottom mold can be rotated and brought into contact with the demoulding mechanism to complete the demoulding of the contact lens. By setting up a limit rod, the rotating frame can be limited so that the rotating frame can drive the second fixed plate and the bottom mold to rotate. By setting up a demoulding mechanism, after the contact lens is formed, the bottom of the bottom mold can be impacted, and the contact lens located in the inner cavity of the bottom mold can be separated during the impact.

[0009] In a preferred embodiment, there are several bottom molds, and the several bottom molds are fixedly connected to the inner wall of the second fixed plate. The first fixed plate is fixedly connected to a support rod on the side away from the limiting rod, and the bottom end of the support rod is fixedly connected to a top mold, and the top mold is extruded and adapted to the inner wall of the bottom mold.

[0010] By setting up several bottom molds, multiple contact lenses can be injection molded at the same time. By setting up a top mold, it can cooperate with the bottom mold to complete the molding of the contact lenses.

[0011] The cam is fixedly provided with an eccentric cylinder at one end and an eccentric cylinder away from the eccentric cylinder, and the outer surface of the cam is rotatably connected to the limiting sleeve, and the limiting sleeve is fixedly connected to the first fixing frame away from the fixing frame, and the outer surface of the fixing frame is fixedly connected to the limiting frame, and the sliding rod is slidably connected to the inner wall of the limiting frame. The end of the sliding rod is fixedly connected to the extrusion sleeve, and the extrusion sleeve is extruded and adapted with the eccentric cylinder, and the extrusion sleeve is fixedly connected to the connecting frame at the side away from the eccentric cylinder, and the inner wall of the connecting frame is fixedly connected to the track tube. The number of the track tubes is several, and the several track tubes are evenly distributed. The inner wall of the track tube is slidably connected with a sliding block, the top of the sliding block is fixedly connected to the extrusion block, and the extrusion block is extruded and adapted with the bottom mold, and the bottom end of the sliding block is fixedly connected to a spring, and the bottom end of the spring is fixedly connected to the inner wall of the track tube.

[0012] By setting a motor, the rotating rod can drive the eccentric cylinder to rotate after the power is connected and the switch is turned on. By setting a limit column and a limit sleeve, the eccentric cylinder can be limited to make the eccentric cylinder rotate. By setting a limit frame, the sliding rod can be limited to make the sliding rod move in the inner cavity of the limit frame, thereby driving the extrusion sleeve to move. By setting an extrusion sleeve, the eccentric cylinder can be squeezed on the extrusion sleeve when the eccentric cylinder rotates. By setting a track tube, the extrusion sleeve can be vibrated when it is squeezed. By setting a sliding block, it can move in the inner cavity of the track tube, and then when the extrusion sleeve vibrates, the extrusion block is squeezed on the lower surface of the bottom mold. By setting a spring, the extrusion block can be squeezed, so that the extrusion block is always subjected to an upward extrusion force.

[0013] As can be seen from the above, an automatic mold ejecting machine for contact lens production has the following improvements and advantages compared with the prior art:

[0014] First: by setting up a mold mechanism, the contact lens can be shaped, and after the contact lens is shaped, the bottom mold can be rotated and the bottom mold can be brought into contact with the demoulding mechanism to complete the demoulding of the contact lens. By setting a limit rod, the rotating frame can be limited so that the rotating frame can drive the second fixed plate and the bottom mold to rotate.

[0015] Secondly, by setting up a demoulding mechanism, after the contact lens is formed, the bottom of the bottom mold can be impacted, and the contact lens located in the inner cavity of the bottom mold can be separated during the impact. BRIEF DESCRIPTION OF THE DRAWINGS
