Description

Technical Field

[0001] The utility model relates to the technical field of plastic mold demoulding, in particular to an automatic demoulding plastic mold mechanism. Background Art

[0002] Molds are generally used in industrial production, using various presses and special tools installed on the presses to press metal or non-metal materials into parts or products of the desired shape through pressure. This special tool is collectively called a mold, which is composed of several groups of parts. This combination has a molding cavity. During injection molding, the mold is clamped on the injection molding machine, and the molten plastic is injected into the molding cavity and cooled and shaped in the cavity. Then the upper and lower molds are separated, and the product is ejected from the mold cavity by the ejection system. Finally, the mold is closed for the next injection molding. The entire injection molding process is carried out in a cycle, and this operation step is called demolding operation.

[0003] In addition, during the demolding operation after the plastic mold is formed, the principle of mold demolding is to use the friction and air pressure difference between the mold and the processed product. In the injection molding production process, mold demolding is a key step to remove the plastic product from the mold by using a demolding mechanism after opening the mold, such as an ejection mechanism, a pull rod mechanism or a push plate mechanism. However, in the existing processing and production links, it is not convenient to perform automatic demolding operations when demolding the plastic mold. Therefore, it is necessary to design an automatic demolding plastic mold mechanism. Utility Model Content
