Problems solved by technology
[0003] At present, automobile wiper grille products are generally 1.6 meters long and 0.7 meters wide. Therefore, if the existing two-color injection molding process is used to produce, the equipment will be expensive and costly. At the same time, two sets of injection molds need to be produced, one set of hard plastic injection molds, one Soft plastic injection mold, so the cost of producing automobile wiper grille injection molding parts will be invisible and the mold manufacturing cycle will be lengthened

Embodiment
[0034] Example: see Figures 1 to 6 , a method for forming an automobile wiper grille provided in this embodiment, the injection molded part is composed of hard rubber and soft rubber, and the product is divided into a hard rubber part 1 and a soft rubber part 2 according to different functions, which includes the following steps:
[0035] (1) Prepare an injection molding machine and an injection mold, set the injection mold on the injection molding machine, and control its working state through the injection molding machine;
[0036] (2) The injection mold includes a soft and hard rubber inlet on the body, a flow channel for draining hard and soft rubber from the inlet into the mold cavity, a soft and hard rubber molding cavity, and a mold that matches the shape of the soft rubber cavity. The slider mechanism, and the moving space reserved for the slider mechanism to move forward and backward, to close or to let out the soft rubber cavity;
[0037] (3) The slider mechanism i...

The invention discloses an automobile windshield wiper grille molding method and an injection mold. The injection mold comprises a flexible and hard glue feeding opening, a flow way, a flexible and hard glue molding cavity, a sliding block mechanism and moving space; the flexible and hard glue feeding opening is formed in a body, and the flow way drains hard glue and flexible glue to flow into a mold cavity from the feeding opening; the sliding block mechanism is matched with a flexible glue cavity in shape; and the moving space is reserved for the sliding block mechanism so as to allow the sliding block mechanism to advance, retreat and move, and the moving space is closed or enables the flexible glue cavity to be empty. The sliding block mechanism comprises a fixed mold sliding block body, a front mold sliding block insert arranged on the fixed mold sliding block body, a sliding block insert matched with the flexible glue cavity, an oil cylinder, springs, limit screws and a pulling buckle mechanism; and the sliding block insert further comprises a locking block connected with the sliding block insert, and the locking block is used for controlling the advancing and retreating motion of the sliding block insert matched with the flexible glue cavity. When the windshield wiper grille injection mold is adopted for carrying out production, the mold is different from a traditional double-color cold; and the mold does not need to be exerted and rotated, and through design and improvement of the sliding block mechanism, the injection molding problem of two different materials is effectively solved, and new attempt and exploration are made for manufacturing of the double-color injection mold.
Description
technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a method for forming an automobile wiper grille and an injection mold for implementing the method. Background technique [0002] The car wiper grill is a plastic part that connects the hood and the front windshield. Its upper part is connected to the windshield with hard glue, usually made of PP material, and the lower part of the wiper is sealed, usually made of soft glue TPS material. This requires that the product injection molding needs to use two or more materials. [0003] At present, automobile wiper grille products are generally 1.6 meters long and 0.7 meters wide. Therefore, if the existing two-color injection molding process is used for production, the equipment will be expensive and costly. At the same time, two sets of injection molds need to be produced, one set of hard plastic injection molds and one set of Soft plastic injection mold, so the cost of pro...
