Description

Technical Field

[0001] The invention belongs to the technical field of molds, and in particular relates to a multi-color car lamp injection mold with rotary demoulding. Background Art

[0002] With the development of society, people's requirements for life experience are getting higher and higher, and the existing multi-color car lights are becoming more and more popular among people.

[0003] In order to make the light source area of ​​the existing multi-color headlights larger, many multi-color headlights are in the shape of long strips. Due to the length of the long strip headlights, a set of molds is usually suitable for producing products of one color of plastic raw material. The production of existing multi-color headlights is usually to produce the product with one color material on a set of molds first, and then take it to another set of molds to produce it with another color material. Multiple sets of molds are needed to complete the production. After a set of molds is completed by injection molding, it is necessary for personnel to move it to the next set of molds until the production of the multi-color headlights is completed.

[0004] In the above production process, after the production of the previous set of molds is completed, the product is taken out and sent to the next set of molds and placed on the injection molding station of the mold, and then the molds are closed to perform injection molding of the next color. However, during the mold closing process, due to the cooperation between the various components of the molds, the position of the product formed by the previous set of molds may be slightly shifted during the re-closing of the molds, causing the next set of molds to perform injection molding of another color on the product injected by the previous set of molds, so that there may be some slight position deviations when the molded products of different colors are combined, thereby affecting the injection molding quality of the products. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to propose a multi-color car lamp injection mold with rotary demoulding. The technical problem to be solved by the present invention is: how to improve the injection molding quality of multi-color car lamps.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions:

The multi-color car light injection mold with rotary demolding also includes a rotating part. The plurality of fixed molds are arranged on the rotating part and the rotating part can drive the plurality of fixed molds to rotate. Each movable mold can be molded with the corresponding fixed mold to form an injection molding cavity. The fixed mold is connected to a guide part, and a slanted ejector block is slidably connected to the guide part. The slanted ejector block can slide obliquely along the guide part. The slanted ejector block has a clamping portion that can be clamped with a workpiece formed in the injection molding cavity. A movable ejector rod is passed through the guide part. The ejector rod is connected to the slanted ejector block and the ejector rod can drive the slanted ejector block to disengage from the workpiece formed in the injection molding cavity.

[0008] Injection molding is performed on multi-color headlights, where one of the movable molds is molded together with the corresponding fixed mold to form an injection molding cavity, and one color of plastic is injected into the injection molding cavity. After the workpiece is formed in the injection molding cavity, the movable mold and the fixed mold of the mold are opened, and the rotating part rotates to drive the fixed mold to the next movable mold position. During the process of the rotating part driving the fixed mold to rotate, the inclined ejector block is connected to the ejector rod, the inclined ejector block is connected to the guide member, and the guide member is connected to the fixed mold. The inclined ejector block, the ejector rod and the guide member are fixed in position with each other, and the inclined ejector block, the ejector rod and the guide member are fixed in position with each other. The clamping part on the block clamps the workpiece formed in the above injection molding cavity, so that the workpiece always keeps its position fixed on the fixed mold, and the fixed mold rotates to a relative position with the next movable mold, so that the next movable mold and the fixed mold are molded together to form an injection molding cavity. During the mold closing process, the clamping part on the inclined top block clamps the workpiece formed in the above injection molding cavity, so it will not cause the position of the injection molded workpiece to be offset due to the mold closing. Therefore, the workpiece formed on the fixed mold can always remain in position, and the plastic of another color can be placed on the fixed mold. Inject it into the injection molding cavity, so that the workpiece is added with another color of plastic injection molding on the basis of the workpiece formed in the previous injection molding cavity, so that the workpiece formed by the plastic material of another color in the injection molding cavity can be combined with the workpiece formed in the previous injection molding cavity without deviation, and inject different color materials into the injection molding cavity formed by the fixed mold and the corresponding movable mold in sequence according to the above steps until the product injection molding is completed.
