[0002] The mold frame is the skeleton of the mold, which is used to fix the mold core during the injection molding process. Before injection molding, the staff needs to place the designed mold core in the mold, and then inject the molten plastic material into the mold core through the injection port set at the top of the mold. This ensures that the plastic material fills the entire mold cavity and forms the desired product shape. The design and setting of the mold frame can facilitate and quickly carry out injection molding production, improve production efficiency and product quality.

This solution has a simple structure and is easy to operate. The bevel block is reset when the first module and the second module are fitted together. BRIEF DESCRIPTION OF THE DRAWINGS
