Problems solved by technology

[0002] At present, the two-color molds of the prior art either need two sets of moulds, or two upper molds, or the mold core needs to be rotated. These two-color molds all have one thing in common, that is, after the upper mold or the movable mold is opened, the mold can be closed again. For injection molding of another color material, the overall mold is larger and the ejection mechanism is more complicated. The maintenance cycle of the mold is shorter and the maintenance cost is higher. At the same time, the entire production cycle is also longer and the production efficiency is lower. lead to higher production costs

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 Shown, a kind of two-color mold, it comprises fixed mold 1 and movable mold 2 (certainly also comprises other components, but because do not relate to the invention point of the present invention, so do not repeat them here), described fixed mold 1 After closing with the movable mold 2, a mold cavity is formed, and the mold cavity is divided into a soft rubber cavity 3 and a hard rubber cavity 4, and the fixed mold 1 is provided with a soft rubber gate 5 and a hard rubber gate 6 , and the soft rubber gate 5 and the hard rubber gate 6 communicate with the soft rubber mold cavity 3 and the hard rubber mold cavity 4 respectively, and the movable mold 2 is slidably connected with the soft rubber mold cavity 3 and the hard rubber mold ...

Abstract

A bi-color die comprises a fixed die body (1) and a movable die body (2). A die cavity is divided into a soft glue die cavity body (3) and a hard glue die cavity body (4). A soft glue sprue (5) and a hard glue sprue (6) are formed in the fixed die body (1) and communicated with the soft glue die cavity body (3) and the hard glue die cavity body (4) respectively. A blade (7) for separating the soft glue die cavity body (3) from the hard glue die cavity body (4) is connected to the movable die body (2) in a sliding manner. One end of the blade (7) is located in the soft glue die cavity body (3). The lower plane of the blade (7) is in flush with the transition position of the soft glue die cavity body (3) and the hard glue die cavity body (4). The end face of one end of the blade (7) is the same as the inner wall of the opposite soft cavity die cavity body (3) in shape. The other end of the blade (7) is located in the fixed die body (2). A drive mechanism for controlling the blade (7) to slide is arranged in the fixed die body (2). Compared with the prior art, the bi-color die has the beneficial effects of being smaller in size, simple in structure, low in maintenance cost and high in production efficiency.

Description

technical field [0001] The invention relates to a two-color mold. Background technique [0002] At present, the two-color molds of the prior art either need two sets of moulds, or two upper molds, or the mold core needs to be rotated. These two-color molds all have one thing in common, that is, after the upper mold or the movable mold is opened, the mold can be closed again. For injection molding of another color material, the overall mold is larger and the ejection mechanism is more complicated. The maintenance cycle of the mold is shorter and the maintenance cost is higher. At the same time, the entire production cycle is also longer and the production efficiency is lower. lead to higher production costs. Contents of the invention [0003] Aiming at the above problems, the present invention provides a two-color mold with relatively small volume, simple structure, low maintenance cost and high production efficiency. [0004] The technical solution used by the present in...
