Device for cutting gate of injection molding product with lens

Abstract

The invention provides a device for cutting a gate of an injection molding product with a lens. The device separates a plurality of lenses from the molding product by automatically cutting the gate of the molding product; and the lenses are formed on each face of the molding product. The device comprises a lower part cutting component, a sliding component, an upper part cutting component, a lifting component and a controller, wherein the lower part cutting component is provided with a lower cutter; the sliding component allows the lower part cutting component to slide on the sliding component; the upper part cutting component is provided with an upper cutter; and the lifting component is used for raising and lowering the upper part cutting component. The lower part cutter separates the lenses from the molding product by cutting the gate of the molding product; the upper cutter is fixed relative to the lower cutter of the lower part cutting component so as to be combined with the lower cutter to cut the gate of the molding product; and the controller is used for controlling the lower part cutting component, the upper part cutting component, the sliding component and the lifting component.

Description

technical field [0001] The present invention relates to a device for cutting a gate of an injection molding product (injection molding product) having a lens body, more particularly, relates to a device for cutting a gate of an injection molding product having a lens body, The apparatus separates a plurality of lens bodies formed on respective faces of the molded product from the molded product by automatically cutting a gate of the molded product. Background technique [0002] An optical pickup lens (hereinafter referred to as 'lens') is used in devices for reading data recorded on eg compact discs (CD) or digital video discs (DVD). A method for manufacturing such an optical pickup tube lens body includes forming a molded product having a plurality of lens body parts integrally formed by hot die casting; cutting the molded product into a plurality of lens bodies; loading the cut lens body coating the lens body on the lens holding jig; and coating both sides of the lens bod...

AI Technical Summary

Problems solved by technology

[0009] However, if figure 2 As shown, in the case of mass-producing a molded product 10 in which a plurality of lens bodies 14 are formed on a support roll 12 oriented in four directions, the disclosed device cannot cut the gate 13 from the molded product 10 due to its structure.

Thus, the patented device is not applicable in this case

In addition, the device is difficult to manufacture due to its complex structure, so its manufacturing and maintenance costs are relatively high

[0010] In addition, since the conventional device is only applicable to the molded product 1 including a small number of lens bodies 5, there is a problem of low productivity.
