Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with rapid mold change. Background Art
[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. Its advantages include high production speed, high efficiency, automated operation, a wide variety of designs and colors, shapes ranging from simple to complex, and sizes ranging from large to small. Furthermore, it produces precise product dimensions, is easily updated, and can produce complex shapes. Injection molding is suitable for mass production and the molding of complex products.
[0003] Existing injection molds are generally used in conjunction with injection machines, and the entire device is a system. Therefore, when the injection mold needs to be replaced, the mold is generally removed from the entire system. However, since the mold is compact and heavy, even a small injection mold is difficult to carry manually. In the existing technology, the mold is generally replaced by a mold changing trolley. The surface of the mold changing trolley is provided with slide rails and pulleys, which can easily slide the mold into the installation position of the injection machine. However, this process requires the mold changing trolley to constantly adjust its position so that the slide rails on its surface can be aligned with the installation position of the mold. This makes mold changing more troublesome and inefficient. Therefore, a quick mold changing injection mold is needed to solve this problem. Utility Model Content
