Description

Injection molding die structure

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

Pressing and molding the 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 inserted. 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 plastic injection molding to smoothly complete the demolding action, the manufacturer will set a pin 13 on the side of the male mold core 122 of the male mold 12, and push the top pin 13 The top column A is used to release the plastic injection molded article from the molding chamber 123 of the male mold core 122, thereby completing the demolding action of the plastic molded article.

The above-mentioned conventional injection molding die 1 assists in the release of the plastic injection molding by providing a top pin 13 on the male mold 12, although the injection molding can be easily released. However, when the injection molding is too large or too light, such as optical lenses, etc., In the conventional injection molding die 1, the top pin 13 is kept at a distance from the male die 122 of the male die 12, so that the plastic injection molding has a long arm with the top stack A1 of the column A, so When the top pin 13 pushes the column A to disengage the plastic injection molding from the molding chamber 123 of the male mold core 122, the plastic injection molding is very likely to be generated in the molding chamber 123 of the male mold core 122. In the case of scratching or deformation, the plastic injection molded product is discarded as a defective product.

Therefore, how to provide an injection molding die structure to prevent the plastic injection molding from being scratched or deformed in the molding cavity during demolding has become an urgent problem for the injection molding mold manufacturer.

The main purpose of the present invention is to provide an injection molding die structure, whereby the plastic injection molding of the conventional injection molding die can be easily worn out of the molding cavity of the male mold, and the scratching or deformation is easily caused.

The main technical means adopted for the above purpose is to provide an injection molding die structure, the mold comprising a mother die and a male die corresponding to the master die, the master die being provided with a mother die a female mold core is disposed in the mother mold cavity, the end surface of the female mold core is provided with a molding chamber, and the molding chamber is connected to the material passage; the male mold is provided with a male mold hole, and the male mold is in the acupoint A male mold is provided, and 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 pin is disposed in the male mold.

The effect that the present invention can achieve by the above technical means is that a second top pin is provided in the male mold of the male mold by the mold, and the second top pin can push the column adjacent to the plastic injection molding. Thereby, the plastic injection molding can be prevented from being scraped when it is separated from the molding chamber of the male mold. The loss of injury or deformation is generated to further improve the use efficiency of the injection molding 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, as shown in Figure 3, the injection molding mold 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 and FIG. 4 together, the male mold 4 is provided with a plurality of male mold cores 41. The male mold core 41 is provided with a male mold core 42. The end surface of the male mold core 42 is provided with a molding chamber 43. The molding chamber 43 is connected to the material channel 44. The male mold 4 is provided with a first top pin 45 near the side of the male mold core 41. The first top pin 45 can be used to remove the material column B, and the male mold core A second top pin 46 is disposed in the vicinity of the molding chamber 43. The second top pin 46 can push the column B adjacent to the plastic injection molding 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 injection molded and released from the mold, the first top pin 45 and the second top pin 46 of the male mold 4 can simultaneously The column B of the plastic injection molded material P is pushed up to disengage the plastic injection molded article P from the molding chamber 43 of the male mold core 42, thereby completing the demolding action. It should be noted that the second top pin 46 disposed in the male mold core 42 is adjacent to the plastic injection molded product P, that is, the distance between the second top pin 46 and the plastic injection molded product P is short. (i.e., the force arm between the two is shortened), so that the plastic injection molded article P can be more smoothly separated from the molding chamber 43 of the male mold core 42 without being scratched or deformed.

The effect of the present invention is that a second top pin 46 is disposed in the male mold core 42 of the male mold 4 by the mold 2, and the second top pin 46 can push the column B adjacent to the plastic injection molding P. Thereby, the plastic injection molding P can be prevented from being scratched or deformed when it is separated from the molding chamber 43 of the male mold core 42, thereby improving the use efficiency of the injection molding mold 2.
