Description

Technical Field

[0001] The present invention relates to the technical field of injection molds, and in particular to a two-color molding mold for a door lock transmission component of a new energy vehicle. Background Art

[0002] like Figure 2-Figure 4 As shown, this product is a small component in the car door lock, which plays a transmission role. Figure 3 The structure shown is the hard plastic part. Figure 4 The structure shown is the soft rubber part. The hard rubber and soft rubber have different structures and colors. The soft rubber part plays a sealing role to prevent dust from entering the structure and causing abnormal noise. In order to ensure the integrity of the structure, it is generally produced by injection molding. Since two injection molding processes are required, the traditional method requires the first injection molded product to be transferred to the second injection mold, resulting in inability to produce continuously and low production efficiency. At the same time, during the second injection molding process, the soft rubber part is directly injected on the hard rubber part, and two columns are provided at the bottom of the soft rubber part to be inserted into the round holes of the hard rubber. This structure results in poor anti-slip effect of the soft rubber part. Summary of the invention

[0068] The working steps of the present invention are as follows:

[0069] S1. The first shot upper mold 2 and the corresponding lower mold 1 below are molded together. At this time, the insertion rod 2301 is inserted into the insertion hole 1204. During the downward movement of the insertion rod 2301, the slide plate 1203 is pushed to move and the second spring 1206 begins to be compressed. At this time, the circular hole mold core rod 1306 moves upward with the movement of the wave groove 1207 and is inserted into the circular hole of the hard rubber part. Fig. 20 As shown;

[0070] S2, inject glue into the first shot glue cup 2101, the glue liquid enters the first shot glue channel 1303 after passing through the first shot glue cup 2102 and the first shot glue tube 2203, and is divided into four paths through the first shot glue channel 1303 to flow to four first shot product cavities. After the injection molding is completed, cooling water circulates in each cooling pipeline to start cooling;

[0071] S3, after the first shot molding, the first shot upper mold 2 is opened. When the mold is opened, the insert rod 2301 moves upward, and the slide plate 1203 is reset under the action of the second spring 1206. The circular hole mold core rod 1306 moves downward along the wave groove 1207 to flow out of the injection molding cavity for the boss structure at the bottom of the soft rubber part;

[0072] S4, the lower mold 1 is transferred to the bottom of the second-shot upper mold 3 under the action of the turntable 4, the second-shot upper mold 3 and the lower mold 1 are molded together, and then glue is injected into the second-shot glue cup 3101, and the glue enters the second-shot glue channel 3402 through the second-shot glue cup 3102 and the second-shot glue injection tube 3203, and is divided into two paths through the second-shot glue channel 3402 to flow to the two second-shot glue injection branch pipes 3403, and is injected into the second-shot product cavity through the second-shot glue injection branch pipes 3403; at the same time, another lower mold 1 and the first-shot upper mold 2 perform a first-shot injection molding process;

[0073] S5. After the second shot is cooled and molded, the second shot upper mold 3 is opened, and the ejector plate 1101 moves upward under the action of the ejector cylinder of the injection molding machine, thereby driving the ejector pin 1102 to move upward, and the final molded product is ejected. After taking it out, the other lower mold with the first shot molded product is transferred to the bottom of the second shot upper mold 3, and the second shot injection molding process is continued. In this way, the two lower molds 1 can perform the first shot injection molding process and the second shot injection molding process alternately.

[0074] The present invention provides a turntable, two lower molds, a one-shot upper mold and a two-shot upper mold. The one-shot molded product does not need to be transferred, and the two-shot molds can be directly produced. At the same time, the two lower molds can be produced continuously and uninterruptedly, and the production efficiency is high. By providing a slide plate seat and an insertion rod, the circular hole mold core rod can move down when the one-shot upper mold is opened and move up when the mold is closed, so that the soft rubber part can be clamped on the hard rubber part through a convex boss, which further has an anti-slip effect and has good product molding quality.

[0075] The present invention provides a turntable 4, two lower molds 1, a first-shot upper mold 2, and a second-shot upper mold 3, so that the first-shot molded product does not need to be transferred, and the second-shot mold can be directly performed. At the same time, the two lower molds 1 can be continuously and uninterruptedly produced, and the production efficiency is high; the present invention provides a slide plate seat 12 and an insert rod 2301, so that the round hole mold core rod 1306 can move downward when the first-shot upper mold 2 is opened and move upward when the mold is closed, so that the soft rubber part can be moved through a convex boss (such as Figure 4 As shown) is clipped onto the hard rubber part, which further prevents it from falling off and ensures good product molding quality;
