Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with easy demolding. Background Technique

[0002] Plastic parts are generally produced and processed by injection molding. For example, the dust suction connecting pipe on a vacuum cleaner is produced and processed by injection molding. Injection molds are usually used in the production and processing process.

[0003] Among them, the injection mold, also known as the injection molding mold, is one of the molds used to produce plastic products. The production process of the injection mold requires the use of advanced numerical control processing technology to ensure the accuracy and quality of the mold. The injection mold is an essential tool in the injection molding process. Its main function is to inject molten plastic into the mold for cooling and forming. The design and manufacture of the injection mold can be customized according to the requirements of the product's shape, size, material, etc. to ensure the production of qualified products.

[0004] In the existing injection mold for plastic part processing, during use, the mold cannot be cooled and dissipated heat in a cycle, resulting in the influence on the mold forming efficiency, which is not convenient for the user to use, thus reducing the applicability of the injection mold. To solve the above technical problems, relevant patents have been proposed in the prior art. For example, the application number is 202020720578.5, the authorized publication number is CN212603048U, and the invention name is an injection mold for plastic part processing. The above patent discloses an injection mold for plastic part processing, including a bottom plate and a water tank. Four corners of the top of the bottom plate are fixedly connected with support rods. The top of the support rods is fixedly connected with a cross plate. Both sides of the bottom of the cross plate are fixedly connected with electric telescopic rods. The bottom end of the electric telescopic rod is fixedly connected with a connecting plate. The bottom of the connecting plate is fixedly connected with an upper mold. The top of the bottom plate is fixedly connected with a cooling seat. A cooling groove is opened at the top of the cooling seat. The bottom of the inner cavity of the cooling groove is fixedly connected with a lower mold.

[0005] The above patent has the advantages of fast forming efficiency and recyclable coolant, and solves the problem that the existing injection mold for plastic part processing cannot cool and dissipate heat in a cycle, resulting in the influence on the mold forming efficiency, thus reducing the applicability of the injection mold. As is well known, generally, after injection and cooling and forming of plastic parts, the formed workpieces are usually unloaded by means of ejection. However, due to the special structure of the dust suction connecting pipe of the vacuum cleaner, it cannot be directly ejected, and forced ejection will cause damage to the workpiece, which has certain deficiencies.
