Description

Optical component mold

The present invention relates to an optical member mold, and more particularly to an optical member which can prevent the plastic injection molding from being scratched or deformed when it is separated from the molding chamber of the male mold, thereby improving the use efficiency of the injection molding mold. Mold.

According to the optical component mold 1, as shown in FIG. 1 and FIG. 2, the mold 1 has a female mold 11 and a male mold 12, and the female mold 11 is provided with a plurality of female mold core holes 111, and the female mold core holes 111 are interposed. The female mold core 112 is provided, and the end of the female mold core 112 is concavely provided with a molding chamber 113; the male mold 12 corresponding to the female mold 11 is also provided with a plurality of male mold holes 121, which are inside the male mold hole 121 A male mold core 122 is inserted, and the end of the male mold core 122 is also recessed with a molding chamber 123, and the plastic molding chambers 113 and 123 can be injection molded.

As shown in FIG. 1 and FIG. 2, in order to allow the optical member to smoothly perform the demolding operation, the operator will set a pin 13 on the side of the male mold core 122 of the male mold 12, and the top pin 13 is used to push the topping material. The column A is thereby used to release the molded article of the optical member from the molding chamber 123 of the male mold core 122, thereby completing the demolding operation of the plastic molded article.

The optical member mold 1 of the above-mentioned conventional use, by providing a top pin 13 on the male mold 12 to assist in demolding the plastic injection molding, has been able to achieve the purpose of facilitating demolding of the optical member. However, when the optical member is too light, such as an optical lens, due to the conventional optical structure The die 1 has a top pin 13 spaced from the male die 122 of the male die 12, thereby causing the optical member to have a long arm with the top stack A1 of the column A, so when the pin 13 is When the top member A is pushed to disengage the optical member from the molding chamber 123 of the male mold core 122, it is very easy to cause the optical member to be scratched or deformed in the molding chamber 123 of the male mold core 122, and further The optical member is discarded as a defective product.

Therefore, how to provide an optical member mold to prevent the optical member from being scratched or deformed in the molding chamber during demolding has become an urgent problem for the injection molding mold manufacturer.

The main object of the present invention is to provide an optical member mold, whereby the conventional optical member can be easily worn out of the molding chamber of the male mold without being scratched or deformed.

The main technical means adopted for the above purpose is to provide an optical component mold, the mold comprising a master mold and a male mold corresponding to the master mold, the master mold is provided with a mother mold acupoint. The female mold core is provided with a female mold core, the end surface of the female mold core is provided with a molding chamber, and the molding chamber is connected with the material passage; the male mold is provided with a male mold core hole, and the male mold core hole is provided therein. There is a male mold, the end surface of the male mold is provided with a molding chamber, and the molding chamber is connected to the material passage, and at least one top pin is arranged in the molding chamber of the male mold.

The effect that the present invention can achieve by the above technical means is that at least a second top pin is disposed in the molding cavity of the male mold of the male mold by the mold, and the second top pin is corresponding to the optical member. a non-optical zone whereby the second pin can push the non-optical zone of the optical member, thereby preventing the optical component from being scratched or deformed when it is detached from the molding cavity of the male die after injection molding, At the same time, the optical member can be prevented from being produced in the non-optical area after injection molding. The raw cuts can simplify the processing of the optical component after injection molding, thereby improving the use efficiency of the optical component mold.

In order to make it easier for your examiner to understand the structure of the creation and the effect it can achieve, the following is a description of the following: First, please refer to Figure 3, the injection molding die 2 of the present invention includes a female mold 3 and a A male mold 4 corresponding to the master mold 3.

Referring to FIG. 3, the female mold 3 is provided with a plurality of female mold cores 31. The female mold cores 31 are provided with a female mold core 32. The end surface of the female mold core 32 is provided with a molding chamber 33. The forming chamber 33 communicates with the channel 34.

As shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the male mold 4 is provided with a plurality of male molds, which are provided with male molds 42 in which the end faces of the male molds 42 are formed. The chamber 43 is connected to the material channel 44. The male mold core 42 is provided with a first top pin 45 at the side of the near-mold core hole 41. The first top pin 45 can be used for the top strip B. Another public The mold core 42 is provided with at least one second top pin 46. The second top pin 46 is disposed in the molding chamber 43. The second top pin 46 is provided with a plurality of branches. The optical member P has An optical zone P1 for light penetration and operation, and a non-optical zone P2 for mounting the optical component P to a lens barrel (not shown), the second top pin 46 is disposed in the molding cavity 43 And corresponding to the non-optical zone P2 of the optical member P, more specifically the second top pin 46 can push the non-optical zone P2 of the optical member P.

For the implementation of the creation mold 2, please refer to the joints of the third, fourth and fifth joints. The mold 2 is mainly used as the molding chamber 33 of the molding part of the female mold core 32 and the molding chamber 43 of the male mold core 42 when the plastic is used. When the molding chamber 33 of the female mold core 32 of the mold 2 and the molding chamber 43 of the male mold core 42 are molded and then demolded, the first top pin 45 and the second top pin of the male mold 4 are demolded. 46, the optical member P can be pushed up at the same time, that is, the first top pin 45 pushes the column B of the optical member P, and the second pin 46 pushes the non-optical area P2 of the optical member P. The optical member P is released from the molding chamber 43 of the male mold core 42, thereby completing the action of demolding. It should be noted that, since the second top pin 46 disposed in the male mold core 42 pushes the non-optical area P2 of the optical member P, that is, the second top pin 46 is directly located on the optical member P. In the non-optical zone P2, the force arm between the two is shortened, so that the optical member P can be smoothly separated from the molding cavity 43 of the male mold core 42 without being scratched or deformed. At the same time, the optical member P can be prevented from producing a processed slit in the non-optical region P2 after injection molding, thereby simplifying the processing of the optical member P after injection molding.

The effect of the present invention is that at least one second top pin 46 is provided in the molding chamber 43 of the male mold core 42 of the male mold 4 by the mold 2, and the second top pin 46 corresponds to the optical member. a non-optical zone P2 of P, whereby the second pin 46 can push the optical member P The non-optical zone P2 can thereby prevent the optical component P from being scratched or deformed when it is separated from the molding cavity 43 of the male mold 42 after injection molding, and can prevent the optical component P from being avoided after the injection molding. The optical zone P2 produces a machined slit, which in turn simplifies the processing of the optical member P after injection molding, thereby improving the use efficiency of the optical component mold 2.

In summary, the optical component mold of the present invention can effectively improve the use efficiency of the optical component mold by the above structure, and should meet the requirements of novelty, practicability and advancement, and propose a new patent application according to law. Please ask your examiner for a detailed examination and grant permission to approve the new patent.
