Improved structure of the die device for continuous forming

This creation is related to polymer molding processing technology, and in particular to an improved structure of a die-making device for continuous molding.

The technique of providing the cavity space required for the polymer molding process by the first mold chamber and the second mold chamber space which are separately formed by the multilayer mold is widely known, but the same mold is specific. There are still differences in the application of the process, especially when the polymer materials of different compositions constitute different parts of the same finished product, the method is still different, for example: As shown in the first figure, the raw materials of different compositions are first injected into the first mold chamber (2) and the second mold chamber (3) of the mold (1) to be formed into the embryo body (2a) (3a). Then, the formed embryo body (2a) (3a) is placed in a third mold chamber (4) and molded into a finished product (4a).

In addition, as shown in the second figure, a material of a specific composition is first injected into the first mold chamber (2), and molded into a correspondingly shaped embryo body (2b), so that the embryo body (2b) is located. In the third mold chamber (4), another material of a specific composition is injected into the third mold chamber (4), and is combined with the existing embryo body (2b) and molded into a finished product.

In order to reduce the number of clamping mechanisms required for mold clamping, the first, second and third molding chambers (2) and (3) are usually present in the same multilayer mold ( 1), the same clamping mechanism can be used to provide the clamping force, and the specific technical content utilizes the first mold chamber (2) and the second mold chamber (3) The respective portions, after being butted against each other, constitute the third mold chamber (4), that is, as shown in the first figure, the first mold chambers (2) are respectively formed on the mold (1) above the mold (1a) Between the middle mold piece (1b), the second mold chamber (3) is formed between the mold piece (1b) and the lower mold piece (1c) in the mold (1), and is drawn away from the middle mold piece (1) After 1b), the third mold chamber (4) is formed between the upper mold piece (1a) and the lower mold piece (1c).

The technical content of forming the third mold chamber (4) by withdrawing the middle mold piece (1b) is limited to those that are necessary for using the same mold mechanism, but in the middle mold Before and after the sheet (1b) is pulled out, the shape of the mold (1) is completely different. Thus, the raw material supply device corresponding to the injection device, such as the injection device, is temporarily unavailable due to the lack of the mold of the corresponding type, for example, In the technique shown in the third figure, a first supply device for supplying the raw material for forming the embryo body (2b), and then supplying the raw material into the first mold chamber (2), and supplying the other material for supply When the raw material is supplied to the second supply device in the third mold chamber (4) for feeding operation, the first supply device is idle and unusable, and when the first supply device is operated, the first The two supply devices are also idle, and the conventional technology is not perfect in terms of manufacturing efficiency and efficient use of equipment.
