Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and more specifically to an injection mold for an automobile instrument panel. Background Art

[0002] The car dashboard is an important part of the car. The car dashboard injection mold is a precision mold specially used to manufacture car dashboard parts. During the manufacturing process of the car dashboard, the molten material is injected into the mold, and the finished product is taken out after cooling to obtain a beautiful car dashboard.

[0003] China Patent Authorization Announcement No.: CN 209775422 U provides an efficient and portable automobile instrument panel injection mold. The portability of the injection mold is improved by installing a universal self-locking wheel under the injection mold, making the movement of the mold more convenient. When it needs to be fixed, it is only necessary to detent the brake on one side of the universal self-locking wheel. A thermometer is arranged on the outer wall of the movable mold plate. The thermometer can observe the temperature of the mold cavity after the injection of the glue, and the mold can be demoulded as soon as the temperature cools down, thereby improving work efficiency.

[0004] In actual use of the prior art, since the molten material is easily mixed with air when injected into the mold, the gas in the mold cannot be completely squeezed out, leaving bubbles. The bubbles will cause dents, pitting and other defects on the surface of the molded automobile dashboard, affecting the quality of the product. Therefore, an automobile dashboard injection mold is proposed. Utility Model Content
