Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with undercut demoulding. Background Art

[0002] Injection mold with undercut body demoulding is a common mold type in the injection molding process. During the injection molding process, plastic material is usually injected into the mold. After cooling and solidification, the molded parts need to be removed from the mold. Injection mold with undercut body demoulding refers to a specially designed mold. Its characteristic is that when demoulding, the mold is inverted and a certain force is applied to make the molded parts fall off the mold.

[0003] In the prior art, an injection mold with an inverted main body for demolding needs to be cooled during demolding. However, most cooling tubes cannot be replaced. Long-term use may cause some impurities to remain inside the cooling tubes, which may deteriorate the cooling effect. The cooling tubes may even be damaged and cannot be used, resulting in a shortened service life. Therefore, in view of the above shortcomings, an injection mold with an inverted demolding is proposed. Utility Model Content
