Abstract

The utility model provides a prevent mould that double-colored injection moulding product drops, includes that one penetrates injection molding chamber and two and penetrates injection molding chamber, and one penetrates including one in the injection molding chamber and penetrates the structure, and two penetrate including two penetrate structure one and penetrate the structure and two penetrate the structure and be unsmooth cooperation structure at the boundary line position of its contact surface in the injection molding chamber. The concave-convex matching structure is in a dovetail structure shape. The utility model increases the combination area of the first injection structure and the second injection structure, enhances the combination force, effectively prevents the separation and falling-off phenomena of the double-color product in the later period of experiment, and has the advantages of simple structure, easy mold stripping, mold cost saving and the like.

Description

Prevent mould that double-colored injection moulding product drops

The technical field is as follows:

the utility model relates to the field of machinery, in particular to an injection mold, and particularly relates to a mold for preventing a double-color injection product from falling off.

Background

In the current central control electronic part of an automobile, a double-color injection molding product is more and more widely applied, in the prior art, two materials used by the double-color product can be selected with different colors or different plastics according to design requirements, and one product is formed by injecting twice on the same injection molding machine through a double-color mold.

The utility model content is as follows:

the utility model aims to provide a double-shot injection mold which increases the combination area of a first-shot structure and a second-shot structure and enhances the combination force of the first-shot structure and the second-shot structure aiming at the defects in the prior art.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model discloses a mold for preventing a double-color injection molding product from falling off, which comprises an injection molding cavity and two injection molding cavities, wherein the injection molding cavity comprises a first injection structure, the two injection molding cavities comprise second injection structures, and the first injection structure and the second injection structure are in a concave-convex matching structure at the boundary line position of the contact surfaces of the first injection structure and the second injection structure.

Furthermore, the concave-convex matching structure is in a dovetail structure shape.

Specifically, the first injection molding cavity, the second injection molding cavity, the first injection structure and the second injection structure are well known in the injection mold industry, and are known to those skilled in the art, and are not described herein again.

Compared with the prior art, the utility model has positive and obvious effect. The utility model effectively prevents the separation and falling-off phenomena of the double-color product in the later period of experiment and the use process, and has the advantages of simple structure, easy demoulding, mold cost saving and the like.

Detailed Description

Example (b):

as shown in fig. 1, the mold for preventing a two-color injection molding product from falling off of the present invention includes an injection molding cavity and two injection molding cavities, the injection molding cavity includes a first injection structure 1, the two injection molding cavities include a second injection structure 2, and the first injection structure 1 and the second injection structure 2 are in a concave-convex matching structure at a boundary line 3 of their contact surfaces.

Further, as shown in fig. 2, the concavo-convex matching structure is in a dovetail structure shape. The dovetail structure enables the tenon-and-mortise structure formed by the first ejection structure 1 and the second ejection structure 2 to be in high-strength joint, so that the first ejection structure and the second ejection structure are prevented from being separated when stressed, and the dovetail structure has good mechanical property and further enhances the binding force between the first ejection structure 1 and the second ejection structure 2.

The utility model not only increases the contact area between the first-shot structure 1 and the second-shot structure 2, but also enhances the binding force between the first-shot structure and the second-shot structure, so that the double-color product can not fall off in the later experiment or use process.
