Injection molds make the mass production of plastic molded products a reality. Injection molds as an important equipment for injection molding. Its design level, the level of technical content of the performance of plastic products has an important significance.
【Introduction of two-plate mold】
Two-plate mold，it means that the mold frame of a mold consists of a front mold and a back mold.
Two-plate mold features:
①Two-plate mold is the most common, its structure is simple, various forms, easy maintenance.
②Two-plate inlet gate is not convenient to directly into the product .
The two-plate mold opening movement process diagram:
Step-by-step decomposition of two-plate mold opening motion:
①When the mold is installed on the injection molding machine, cavity is fixed on the front panel of the injection molding machine and cannot moved. Core can move with the injection molding machine.Due to the tension of the injection molding machine, the core will be separated from the cavity It will separate and stop at a set distance.
②、Under the push of the ejector pin of the injection molding machine, the ejector pin plate drives the ejector mechanism (ejector pin, cylinder, angle ejector , etc.) to start ejecting movement, and the finished product is ejecting (automatically falling or taken out by the manipulator).
【Introduction of three-plate mold】
Three plate mold refers to the mold frame has three pieces, the front mold, the back mold and a removable stripper plate on the front mould.
Three-panel mold features:
①、Three-platen molds are relatively expensive
②、The location of the gate on the surface of the product is more flexible, leaving only a small point on the surface of the product, which is suitable for products with high appearance requirements.
Three-plate mold opening movement process diagram:
Step-by-step decomposition of the three-plate mold opening motion:
①、The mold is first opened from parting surface
②、Continue to open the mold, from the parting surface 2 open the mold. Prepare the product for removal.
③、Finally, open the mold in the parting line 3 to separate the runner from the runner plate. Remove product and runner.
