Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of injection mold, more particularly, to a rapid demolding injection mold. BACKGROUND

[0002] Injection molding machine is a mechanical device commonly used in industrial production, which principle is to heat the plastic raw material to a molten state, get the melt formed by the plastic raw material, and then inject the melt into the mold prepared in advance, and then extrude the model in the mold to get the product after the melt is cooled.

[0003] When the injection molding is completed and the injection molding model needs to be taken out, the model is difficult to take out because the plastic raw material in the molten state is formed by pressurizing in the mold, and the high temperature causes the model to adhere to the inner wall of the mold. Generally, the model needs to be cooled before being taken out, and then the model is pushed out by the ejector pin in the mold. The existing cooling method of the mold is relatively single, which only cools the mold through the cooling liquid in the water cooling channel in the mold, and cannot quickly cool the mold, thereby delaying the time of taking down the model. In order to better take down the model in the mold, the mold is usually sprayed with a mold release agent before injection molding, so that the mold needs to be heated after spraying to form a thin film of the mold release agent between the mold and the model, preventing the rubber plastic or other materials from being bonded to the mold, and facilitating the separation of the model and the mold. However, the mold needs to be heated to the temperature at which the mold release agent becomes a thin film after spraying, thereby wasting a lot of time in the process of cooling the model and heating the mold to the temperature at which the mold release agent becomes a thin film, resulting in low efficiency of the injection molding model and causing loss to a certain extent.

[0004] Therefore, the present application provides a rapid demolding injection mold to solve the above problems. SUMMARY
