Problems solved by technology

[0003] However, conventionally, when the fixed-side mold and the movable-side mold used for molding optical devices etc. are combined, the alignment accuracy is low
In particular, even in the case of using the method of the prior art document, since the tapered concave portion and the tapered convex portion need to be processed separately, the assembly processing technology is required to have high alignment accuracy, and since the upper and lower parts There is a gap between the fixed side product core and the movable side product core related to the fixed side molding surface and the movable side molding surface, and the decenter (decenter) that causes the center deviation between the upper and lower cavities is difficult to carry out. fix

Embodiment Construction

[0042]The purpose, specific advantages, and innovative features of the present invention will become more apparent from the following detailed description and preferred embodiments associated with the accompanying drawings. In this specification, when referring to the components of each drawing, the reference symbols are limited to the same components, and even if they are shown in different drawings, the same symbols are used as much as possible. In addition, terms such as "one side", "the other side", "first", and "second" are used to distinguish one constituent element from other constituent elements, and the constituent elements themselves are not limited by the terms. In particular, the upper and lower directions of the present invention are Figure 2b Based on the drawing shown in , the part forming the upper core and upper formwork on one side is called "upper part", and the part on the other side forming the lower core and lower formwork plate is called "lower part". ...

Abstract

Provided are a molding device and a method for operating the same. Unilateral of the present invention is formed inside an upper template and a lower template. The molding device arranges combination of cavities of the upper and lower pin cores on one inner surface of the upper or lower template by forming a fitting line of an upper core and a lower core, in which cavity is formed, in either upper or lower direction from the fitting line of the upper and lower templates.

Description

technical field [0001] The present invention relates to forming apparatus and methods of operation thereof. Background technique [0002] In general, for optical devices made of resin materials such as lenses, the fixed side mold and the movable side mold are formed on the upper and lower parts respectively, and the molding surfaces are aligned and combined to form a cavity between the two. Molten resin is injected into the cavity for molding. In order to align the arrangement of the optical components, a cylindrical guide sleeve is generally provided on the fixed side mold for injecting a guide pin protruding from the lower surface of the movable side mold to align the fixed side. The arrangement that the mold and the movable side mold are combined at the upper and lower parts. For example, as described in Japanese Laid-Open Publication No. 2009-120097, the bottom surface of the tapered groove and the tapered convex part are respectively formed for the injection combinati...
