After the first injection molded product 15 is completed, the male mold 11 and the female mold 12 are opened, and then the lateral slider 13 is controlled laterally by the actuation link 14 After moving, the male mold 11 and the female mold 12 are again clamped, and the second injection molded product 16 is formed on the first injection molded product 15 of M394238 99. 6.2 9 (see the first tT1^T: Therefore, by the operation of the heavy composite mold, the injection, and the mold opening, it is possible to form a finished product including two different materials of the first injection molded product 15 and the second injection molded product 16. However, please refer to Section 2 The first injection molded article 15 is basically formed by a male mold buckle, a female mold 12 (refer to the left side of FIG. 1), and a mold hole surrounded by the lateral slider 13, and is formed by emitting a sleek plastic, and the second shot is formed. Producing 16 phases, and repeatedly applying the shots to the first injection molded article 15 as shown in Fig. 2, therefore, The final appearance (in the current round type, that is, the second injection molded article 16 outer surface, however, some of the products may also be part of the outer surface of the first injection molded article 15 due to design) will be affected by the side The slider line 161 is formed on the surface of the sliding, between the blocks 13, and between the male mold n and the female mold 12; although the structure is not defective, the overall appearance is ' However, it is very influential, especially because the appearance of consumer electronics products has a considerable impact on the subjective impression scores of consumers. Therefore, electronic products are not favored by consumers, in other words, the competitiveness of products will be greatly reduced. [New Content] In the above-mentioned topics, the main purpose of this creation is to provide a two-stage injection molding mold that uses a two-stage molding method with a movable male mold and a push-up mechanism, thereby eliminating the appearance of the final product. The line of the line greatly improves the aesthetics of the finished product and thus the competitive potential of the product. Therefore, in order to achieve the above objectives, the present invention discloses a seamless two-shot injection molding mold. The utility model comprises a male mold base, a female mold, a full sliding slider, a movable male mold, and a pushing mechanism; the bottom of the female mold has a recess and is disposed above the male mold base, and the lateral sliding block is disposed on the lateral side of the female mold , and the yoke can't be combined with the male mold base and the female mold to shoot the mold cavity, and the molded first-injection molded product can be injected. After the mold is opened, the lateral slider is withdrawn. The mechanism is a good model, so that the movable male mold placed on the outside of the base of the male mold moves up and closes to the bottom of the female mold, and forms a second injection mold hole and shoots the second injection molded product. Injection molding. 4 M394238 正9V·/9曰 Complementary, by the two-stage production method, in the second injection molding, the screen is removed by the conventional method, and the movable male model is used. The second injection molded product is directly formed by breaking the bottom of the female mold; therefore, the conventional gap between the lateral sliders and the gap between the male and female molds can be eliminated. Slider line that greatly enhances the overall appearance of the final product and Observability, and to improve product competitiveness. In order to further understand the purpose, characteristics and functions of this creation, the following is a detailed description of the following: σ 1 [Embodiment] ± According to the seamless two-shot injection molding die disclosed in this creation, please refer to Figure 3. This is the stereoscopic circle of the appearance of the seamless double-shot injection molding die exposed by the author. According to the creation of the seamless double-shot injection molding die, the male mold base 20, the female mold 30, the lateral slider 40, the movable male mold core 50, and the push-up mechanism 6〇 are included. The figure shows that the 'male base 2〇, the movable male mold 5〇, the lateral slider 40 and the female mold 30 are stacked vertically in a schematic manner, and the push-up mechanism 6〇 is disposed on one side and is in the movable male mold 50. . The top surface of the male mold base 20 has the appearance shape of the finished product to be formed, and the bottom of the female mold has a recess 31 and is disposed above the base 2 of the male mold; after the mold is closed, the lateral slider moves to be disposed in the female mold. 30 lateral direction, as shown in Fig. 4, it can only be seen that the lateral slider 40 is located at _ (there are one lateral slider 4〇 on each side), which is three-dimensional, and therefore can have one side on each side. To the slider 4 (a total of four complete closed 30 shape 31, and together with the top surface of the male mold base 2 (), the bottom surface of the base 3 to form the first injection hole 71. In order to ensure that the parts are combined In the process of the mold, there is no damage. After the mold is clamped to the mold base 2 and the mold is clamped, the side to the relative position is better. ^ = This can be injected for the -first injection mold hole 71, and the injection is melted.
