[0002] With the rapid development of automobiles, the degree of refinement of automobiles is getting higher and higher, and the requirements for auto parts are also getting higher and higher. This requirement is not only reflected in the quality of parts, but also in the control of the manufacturing process of parts. The protective shell of the electronic equipment inside the car is usually produced by injection molding into the mold, but the current technical considerations are not perfect, and it has the following disadvantages: 1. When the raw material for automotive injection molding is too thick, it is easy to generate air bubbles after the raw material is injected into the mold cavity. porosity, thereby reducing the density of the injection plastic, and at the same time, cracks are prone to occur during the cooling molding process, resulting in a decrease in quality; The left and right ends are not completely separated from the mold, which causes the finished product to be subjected to the thrust of the bottom and the torque on both sides, resulting in rubbing marks on the surface of both sides when the finished product is pushed out, which affects the appearance of the product

The invention discloses a precision rapid prototyping automotive electronics mold based on vibration wave processing. Adjust the structure, during the working process of the mold, after the raw material is injected into the mold cavity, the vibration transmission structure forms a transverse mechanical wave on the raw material, so that the raw material injection is distributed more evenly in the mold, and at the same time eliminates the air bubbles in the raw material to avoid cracks after cooling In addition, during the demoulding process, it can effectively avoid rubbing marks on the left and right sides of the molded product, and improve the smoothness of the surface of the molded product.
