Description

Technical Field

[0001] This utility model relates to a double-shot mold and a two-color molding machine, belonging to the field of mold technology. Background Technology

[0002] When molding assemblies, such as Figure 5 The product to be molded shown should be molded in the male mold according to the general mold parting concept. For example, the parting surface indicated by PL should be molded in the male mold. In general two-shot molding, the glue position of the second shot must be on the nozzle side of the injection machine. The cavity on this side can be made into different shapes. However, part of the glue position of this product is on the rotating side of the injection machine, so ordinary two-shot molding cannot be used. The traditional practice in the industry is to use two molds to mold separately on the injection molding machine. Specifically, after molding the first assembly in the first mold, the first assembly is pre-embedded in the second mold, and then the second assembly is molded.

[0003] While this method can achieve the molding of assemblies, the cumbersome steps make it difficult to guarantee molding efficiency. Therefore, in order to ensure molding efficiency, there is an urgent need for a double-shot mold that can continuously mold. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a double-shot mold and a two-color molding machine. By setting a first set of molds, a first-shot female mold slider and a first-shot female mold core, a first male mold slider and a first male mold core are set together. A second set of molds is formed by a second-shot female mold slider, a second-shot female mold core, a second male mold slider and a second male mold core. During double-shot molding, the mold mechanism is changed by rotating the machine base to complete the exchange of different glue positions, which can realize continuous molding on a two-color molding machine.

[0005] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution:

[0032] like Figures 1-4 As shown, this embodiment provides a double-shot mold, including a first telescopic mechanism 1, a second telescopic mechanism 2, a third telescopic mechanism 3, a fourth telescopic mechanism 4, a first-shot female mold slider 5, a second-shot female mold slider 6, a first-shot female mold core 7, a second-shot female mold core 8, a first male mold slider 9, a first male mold core 10, a second male mold slider 11, and a second male mold core 12, wherein...

[0033] The first telescopic mechanism 1 is connected to one end of the female mold slider 5, and the other end of the female mold slider 5 is engaged with the female mold core 7, the first male mold slider 9 and the first male mold core 10;

[0034] The second telescopic mechanism 2 is connected to one end of the second female mold slider 6, and the other end of the second female mold slider 6 is engaged with the second male mold slider 11 and the second male mold core 12;

[0035] The third telescopic mechanism 3 is connected to one end of the first male mold slider 9, and the other end of the first male mold slider 9 is engaged with the female mold slider 5, the female mold core 7 and the first male mold core 10.

[0036] The fourth telescopic mechanism 4 is connected to one end of the second male mold slider 11, and the other end of the second male mold slider 11 is engaged with the second female mold slider 6, the second female mold core and the second male mold core;

[0037] In the mold-closed state, the first injection female mold slider 5, the first injection female mold core 7, the first male mold slider 9, and the first male mold core 10 form the first cavity;

[0038] In the mold-closed state, the second-shot female mold slider 6, the second-shot female mold core 8, the second male mold slider 11, and the second male mold core 12 form the second cavity.

[0039] In the above technical solution, a first set of molds is formed by setting a first injection female mold slider 5, a first injection female mold core 7, a first male mold slider 9, and a first male mold core 10. A second set of molds is formed by setting a second injection female mold slider 6, a second injection female mold core 8, a second male mold slider 11, and a second male mold core 12. During double injection molding, the mold mechanism is changed by rotating the machine base to complete the exchange of different glue positions, which can realize continuous molding on a two-color molding machine.

[0040] In practical use, the two sets of molds are positioned and installed on the same two-color molding machine. The female mold side is positioned on the nozzle side of the machine, and the male mold side is positioned on the turntable side of the machine. It is essential that the female mold core 7 of the first injection is installed at the first injection nozzle position, and the female mold core 8 of the second injection is installed at the second injection nozzle position. During the first molding process, the first cavity formed by the female mold slider 5, the female mold core 7, the first male mold slider 9, and the first male mold core 10 forms the first product. Then, the first telescopic mechanism 1 retracts the female mold slider 5, and secondly, during the separation of the moving and fixed molds, the third telescopic mechanism 3 retracts the first male mold slider 9. This set of molds forms the shape of the first-injection product. However, this product is still covered by the male mold side and is not ejected (the molding machine at the first injection position does not have an ejection mechanism).

[0041] Simultaneously, in another set of molds, the first molding is also completed. The second cavity, composed of the second-shot female mold slider 6, the second-shot female mold core 8, the second male mold slider 11, and the second male mold core 12, forms the second product. First, the second telescopic mechanism 2 retracts from the second-shot female mold slider 6. Then, during the separation of the moving and fixed molds, the fourth telescopic mechanism 4 retracts from the second male mold slider 11. The product formed by this set of molds has a cavity structure including both first-shot and second-shot processes, so it is not a double-shot product (only the second-shot nozzle fills the entire cavity). Finally, the product is ejected by the machine.

[0042] After completing the above actions, the male mold side rotates 180° under the rotational force of the machine turntable. This allows the male mold side of the first injection to close with the female mold side of the second injection, and vice versa. That is, the first cavity, composed of the female mold slider 5, the female mold core 7, the second male mold slider 11, and the second male mold core 12, forms the first product; the second cavity, composed of the female mold slider, the female mold core 8, the first male mold slider 9, and the first male mold core 10, forms the second product (this cavity also contains the first product formed by the first cavity), thus completing the entire double-shot molding process. Example 2

[0043] The double-shot mold provided in this embodiment differs from the double-shot mold provided in Embodiment 1 in that:

[0044] like Figure 4 As shown, the two-shot master mold slider 6 has a two-shot forming groove 13 on the basis of the one-shot master mold slider 5.

[0045] The first male mold slider 9 and the second male mold slider 11 have the same structure, and the first male mold core 10 and the second male mold core 12 have the same structure.

[0046] The first telescopic mechanism 1, the second telescopic mechanism 2, the third telescopic mechanism 3, and the fourth telescopic mechanism 4 all include hydraulic cylinders.

[0047] It also includes a first limiting rail, of which there are two. The two first limiting rails are symmetrically installed on the fixed end of the first telescopic mechanism 1 or the second telescopic mechanism 2 and are located on both sides of the telescopic direction of the first injection mold slider 5 or the second injection mold slider 6. The first limiting rail is adapted to the first injection mold slider 5 or the second injection mold slider 6.

[0048] It also includes a second limiting rail, of which there are two. The two second limiting rails are symmetrically installed on the fixed end of the third telescopic mechanism 3 or the fourth telescopic mechanism 4 and located on both sides of the telescopic direction of the first male mold slider 9 or the second male mold slider 11. The second limiting rail is adapted to the first male mold slider 9 or the second male mold slider 11. Example 3

[0049] This embodiment provides a two-color molding machine. By adapting to the two-shot mold described in Embodiment 1, the mold mechanism is changed by rotating the machine base during two-shot molding to complete the exchange of different glue positions, thereby enabling continuous molding on a single two-color molding machine.

[0050] The female mold side of the two-color molding machine is positioned on the nozzle side of the machine base, and the male mold side is positioned on the turntable side of the machine base. The first female mold core 7 is installed at the first nozzle position of the two-color molding machine, and the second female mold core 8 is installed at the second nozzle position.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
