Description

Technical Field

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods.

[0003] In traditional equipment, the shell after injection molding often requires a long time to cool naturally or slowly cool through external auxiliary equipment, which not only prolongs the production cycle, but may also cause shell deformation and dimensional instability, affecting the assembly accuracy and feel of the final product.

Then the first cylinder 7 drives the injection mold 5 to move upward, and then the conductive part 13 contacts with the limiter 17, and then the injection molded part is demolded by the demolding part 11. Then the second cylinder 15 is started again, so that the connection between the limiter 17 and the conductive part 13 is disconnected, and the demolding part 11 is reset by the spring 14 to prepare for the next round of injection molding.
