Description

Technical Field

[0002] The injection molding device is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding, also known as injection molding, is a molding method that combines injection and molding. Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to the high-pressure injection of the heated and melted plastic into the mold cavity by the injection molding machine, and after cooling and solidification, a molded product is obtained. 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 complex-shaped parts. Injection molding is suitable for mass production and complex-shaped products and other molding processing fields. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and after cooling and solidification, a molded product is obtained. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods. However, during the removal of the upper mold, the plastic product cannot be completely adhered to the lower mold side, and some of it adheres to the upper mold, causing the product to be stretched and deformed.

[0031] In this embodiment, the cooled mold is pushed upward by the push rod 13 and the upper mold 10 is restored to its initial state. Then, the mold falls to the top of the lower mold 11 under the action of gravity, and the remaining residue in the gate 7 is cooled together with the mold. Then, the hydraulic pump drives the hydraulic telescopic rod 2402 to extend, and the hydraulic telescopic rod 2402 pushes the push plate 2403 to move the mold toward the cutting knife 2407. Then, under the action of the cutting knife 2407, the excess part of the mold is cut off. Then, as the push plate 2403 continues to push, the mold is pushed away from the guide plate 2408. The remaining waste enters the waste box 2405 for collection and then is reused after processing, saving raw materials.
