Description

Technical Field

[0001] This utility model relates to the field of demolding equipment technology, and in particular to an automatic demolding device for automotive dashboards. Background Technology

[0002] The car dashboard is an important part of a car. The car dashboard is made of plastic and is usually made by injection molding. The injection mold is an indispensable tool in the injection molding process. The injection molding of the car dashboard involves injecting hot molten plastic material into a closed cavity in the injection mold that has the shape of the car dashboard. After the plastic material cools and solidifies, the mold is opened and the solidified car dashboard product is ejected to obtain the molded product.

[0003] In existing injection molds, the plastic material is heated during the injection process. Even after the plastic material cools and solidifies, the resulting car dashboard still retains heat. When unloading the car dashboard after it has been formed, workers usually unload it directly with the help of demolding components. As a result, workers are at risk of burns when unloading the hot car dashboard, which poses a high risk to them.

[0004] While the patent with publication number CN221161365U solved the problem of burns caused by workers directly cutting materials, its technical solution still has the following drawbacks. For example, there is no guiding mechanism to limit the upper mold when it is raised and lowered, and there is no positioning device for the lower mold before and after flipping. This makes it easy for the upper and lower molds to misalign when they are closed and connected, which affects the quality of the product. In addition, its demolding component is only equipped with one ejector rod, which results in small force on the entire product and uneven force distribution, affecting the demolding effect.

[0005] Therefore, this application proposes an automatic demolding device for automotive dashboards to solve the aforementioned problems. Utility Model Content
