Rotating core type dual-color injection mold and machining device

Abstract

The invention discloses a rotating core type dual-color injection mold and a machining device, and belongs to the field of plastic processing. The rotating core type dual-color injection mold and themachining device are used for solving the problems that in practice, after mold separating, two moving molds are in an external state, after the two moving molds rotate by 180 degrees, residual liquidon the moving molds is prone to being leaked, finally, overall sealing of an injection molding machine is not tight, and the phenomenon of glue leaking is caused. The rotating core type dual-color injection mold comprises a fixed mold, a moving mold and a dual-color injection mold assembly used for communicating with the moving mold. The dual-color injection mold comprises a rotating core rotating mold, a rotating core rotating plate, a rotating core connecting plate, a first injection molding mechanism and a second injection molding mechanism. A first color channel is arranged in the first injection molding mechanism, and a second color channel is arranged in the second injection molding mechanism. According to the rotating core type dual-color injection mold and the machining device, afirst injection molding sealing protection sleeve and a second injection molding sealing protection sleeve are reasonably utilized, the phenomenon of glue leaking generated on a joint is reduced, andeven though glue is leaked, generated glue can only be blocked in the first injection molding sealing protection sleeve and the second injection molding sealing protection sleeve.

AI Technical Summary

Problems solved by technology

However, in the prior art, there are still the following defects. Due to the influence of the purpose of making products, the two-color injection molding machine needs to be equipped with two identical machine plasticizing injection devices, that is, two moving molds and two fixed molds. During injection molding, the two movable molds are required to be able to rotate 180°, the movable mold and the fixed mold are repeatedly divided and closed, and the two movable molds are required to be interchangeable after the mold is divided. In practice, the two movable molds are in the In the external state, after the two movable molds are rotated 180°, it is easy to cause the residual liquid on the movable mold to leak, and eventually the overall seal of the injection molding machine is not tight, and glue leakage will occur

In particular, once the glue leaks on the heating ring, the heating ring will be wrapped due to the leaking glue, which will cause a short circuit of the heating ring
