Description

A mold connection mechanism for easy demoulding

technical field

The utility model relates to the technical field of moulds, in particular to a mould-connecting mechanism for easy demoulding.

Background technique

In the mold industry, various molds and tools are used for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry".

In a common mold, the material is heated and melted inside the heating device to a liquid state, and then the heating device is tilted so that the liquid material is introduced into the mold. After the liquid material enters the inside of the molding cavity of the mold, it is cooled and formed. After the liquid material is inside the forming cavity After cooling and forming, the mold is separated and the blank is taken out. This is a common way to use the mold. Since the common mold is usually composed of two parts, the upper mold and the lower mold, and the upper mold and the lower mold are connected by connecting structures (such as bolts, buckles, etc.) on the outside, the upper mold must be removed first when the blank is taken out Separate from the lower mold. When the blank is taken out, inconvenient demoulding is a common problem in the mold, and some molds have a placement slot at the bottom, and a top plate is installed inside, and the bottom of the top plate is equipped with a lifting structure. Cooperate with the top plate to eject the blank, but in this way, because the blank is closely attached to the inner wall of the mold forming cavity, the use of the ejection method is easy to cause damage to the blank and the inner wall of the mold forming cavity , which leads to the failure of mold processing, so a mold connection mechanism for easy demoulding is proposed.
